Letters to Shareholders 

Dear Shareholders, 

During 2023, a challenging year, the Board and Management team worked together focusing on the most important 
operational issues that could improve performance and shareholder returns. These efforts resulted in a smaller and 
more efficient workforce, management team and board of directors that will continue to align the company objectives 
with shareholders’ interests without sacrificing on safety or corporate governance. 

In 2024, we will continue to work through a lower than historical annual production output while we chart a course to 
the higher-grade resources discovered in last year’s drilling campaign. Metal prices have been working in our favor 
during the first quarter  and more recently, the foreign exchanges rates have been  improving as well that  have a 
positive economic impact on our Mexican operations. 

We shall strive to maintain a safe, fair and diversified workplace, with attention to our environment stewardship along 
with a continuance to contribute to our local communities in a significant way. Reflective of our 2024 objectives, there 
has been little change to our compensation policies, and we have taken measures to limit stock-based compensation 
and dilution during a period of share price underperformance. 

To ensure the long-term success of the company, the board has mandated to management that capital resources, 
which would otherwise have been applied to dividends, be redirected to our exploration program at the Don David 
Gold Mine. We remain committed to a maintaining a disciplined balance sheet with a focus to expand our mineral 
resources and cash balance through exploration, improved operational returns and potentially an accretive merger 
and acquisition target. 

We are grateful for the continued support of our shareholders and various stakeholders throughout 2023 and onto 
2025. 

Kind regards, 

Ron Little 
Interim Chair, Gold Resource Corporation 

 
 
 
 
 
 
 
Letters to Shareholders 

Dear Shareholders, 

As the President and Chief Executive Officer of Gold  Resource Corporation, I’m  proud of the team that we  have 
established and what we accomplished during a very difficult year. Throughout the year, we continued to build on a 
strong  foundation  for  the  Company  and  further  identify  the  best  path  forward  that  will  ensure  sustainability  of 
operations and create long term value for our Gold Resource shareholders and the communities in which we operate. 
I must reiterate that we have an excellent technical and management team and that we have the right  people in 
place to successfully drive Gold Resource Corporation as we move through and beyond 2024. 

Exploration activities at our Mexico operation, the Don David Gold Mine, during 2023 resulted in positive results and 
increased the grade of the material in reserves and resources. This exploration work will continue into 2024, including 
in the areas of mineralization known as the Three Sisters, Gloria, and Morena areas, from which will form a large 
part of the Company’s future. Steps have also been made during the year by our operations team to identify and 
implement  cost  reduction  practices  and  improve  our  existing  processes  and  procedures.  We  have  undergone  a 
series of testing throughout our plant to find ways to increase recovery and we are seeing positive results from this 
review. We have also continued to significantly improve our adherence to safety standards and expand the training 
programs for employees. 

In October 2023, we published our preliminary economic analysis of the Back Forty project, and it confirmed our 
initial  assumptions  of  the  project  when  we  acquired  it.  The  new  project  layout  and  mine  plan  has  a  much  lower 
environmental  impact  and  carries  a  life  of  mine  NPV  at  6%  discount  of  $215  million  using  very  conservative 
commodity prices and demonstrates the economic viability of the project. The company will continue to monitor the 
economic environment to determine the best time to move forward with the Back Forty project. 

For our stakeholder base, including our investors, our strategy is to provide optimal near and long-term value by 
unlocking  the  full  potential  from  our  assets  and  execution  on  strategic  growth  opportunities.  The  foundation  to 
achieve  this  objective  for  near-  and  long-term  will  center  around  the  Don  David  Gold  Mine  and  identifying  other 
strategic growth opportunities. For Mexico operations, our focus is to identify and progress on highly prospective 
underground  exploration  targets,  optimize  mine  sequencing,  and  achieve  maximum  mill  processing  efficiencies. 
Concerning  other  strategic  growth  opportunities,  we  will  work  to  identify  accretive  targets  with  an  emphasis  on 
leveraging bullish commodity prices, generating free cash flow, and limiting jurisdictional risk. 

While we did experience some challenges in 2023, we were able to focus on areas within our control to continue to 
lay out a strong foundation from which to deliver positive operational results and grow the Company. I look forward 
to reporting on our progress throughout the year. 

Kind regards, 

Allen Palmiere 
President & CEO, Gold Resource Corporation

2023 HIGHLIGHTS 

Highlights  for  the  full-year  ended  December  31,  2023  are  summarized  below  and  discussed  further  in  our  Management’s 

Discussion and Analysis: 

Corporate and Financial: 
 

The Company closed the year with a $6.3 million cash balance as at December 31, 2023. The decrease of $17.4 million 
from December 31, 2022 is mainly attributable to a cash outflow of $12.5 million for capital investments and a cash outflow 
of $5.2 million from operating activities for 2023, which included $7.8 million of income tax payments for the tax years 
2022  and  2023,  exploration  investment  of  $4.2  million  at  the  Don  David  Gold  Mine  (“DDGM”),  and  $1.6  million  in 
spending on the Back Forty Project optimization work, offset by a $0.2 million increase in the value of cash due to the 
strengthening of the peso. 

  Working capital at December 31, 2023, was $15.2 million, a 29% decrease from the December 31, 2022, working capital 

of $21.4 million. The decrease is primarily driven by the decline in cash balance discussed above. 

  DDGM total cash costs (after co-product credits) and total all-in sustaining cost per gold equivalent (“AuEq”)1 ounce sold 
were  $1,250  and  $1,630,  respectively.  See  Item  7.  Management’s  Discussion  and  Analysis  of  Financial  Condition  and 
Results  of  Operations—Non-GAAP  Measures  below  for  a  reconciliation  of  non-GAAP  measures  to  applicable  GAAP 
measures. 
The Company’s At-The-Market Offering Agreement with H.C. Wainwright & Co., LLC (the “Agent”), which was entered 
into in November 2019 (the “ATM Agreement”), pursuant to which the Agent agreed to act as the Company’s sales agent 
with respect to the offer and sale from time to time of the Company’s common stock having an aggregate gross sales price 
of up to $75.0 million, was renewed in June 2023. 

 

  On February 13, 2023, the Company announced the suspension of future quarterly dividends to protect the balance sheet 

 

and to focus capital resources on exploration and resource and reserve development.  
In November 2023, the Company’s Board of Directors decided to initiate a formal review process, with the assistance of 
outside financial and legal advisors, to evaluate strategic alternatives for the Company. The comprehensive process, which 
is ongoing, is evaluating a broad range of options to maximize shareholder value, including a potential sale or merger of 
the Company. 
Don David Gold Mine: 
 
 

The DDGM safety program aims to bolster the overall health and safety culture of our employees. 
In  2023,  two  incidents  resulting  in  lost  time  were  recorded.  Despite  their  low  potential  for  harm,  comprehensive 
investigations were conducted, and requisite measures were implemented accordingly. 
The full-year lost time injury frequency rate per million hours was 0.96, which is substantially below the 3.95 Camimex 
(Mexican Chamber of Mines) benchmark.2 

 

  DDGM received the Mexican Empresa Socialmente Responsable (“ESR”) award in 2023 for the ninth consecutive year. 
  DDGM produced and sold a total of 31,085 gold equivalent ounces, comprising of 18,534 gold ounces and 1,036,229 silver 

ounces, sold at an average price per ounce of $1,955 and $23.68, respectively. 

  During the year, our exploration program was executed as planned, maintaining a dual focus on both infill and expansion 
drilling,  with  encouraging  results  from  targets  in  the  Switchback,  Arista,  and  Three  Sisters  vein  systems.  The  2023 
expansion (step-out) drilling program proved highly successful, culminating in the discovery of the Gloria vein system, 
located immediately north of the Three Sisters system, as well as successfully testing the projected northern extensions of 
the Splay 31 and Marena North veins of the Arista system. 
The Company purchased over two thousand tonnes of tailings material for $0.3 million from a third-party mining operation 
as a collaborative initiative with the local community at the end of 2022. Some of this material was processed in early 2023 
to ensure the proper environmental treatment and storage of the material. 

 

  During the fourth quarter of 2023, negotiations were successfully undertaken to decrease the royalty fee from 5% to 3% for 

the mining claims at La Tehuana, El Aguila, and Mina El Aire. 

Back Forty Project: 
  Optimization work related to the metallurgy and the economic model for the Back Forty Project in Michigan, USA was 
completed, and the Company filed the Back Forty Project Technical Report Summary, which was prepared in accordance 
with subpart 1300 of Regulation S-K (“S-K 1300”), as Exhibit 96.1 to the Form 8-K filed on October 26, 2023 (the “Back 
Forty Project Technical Report Summary”). Results of the work indicate a more robust economic project with no planned 
impacts to wetlands that is more protective of the environment, which should facilitate a successful mine permitting process. 

1 Gold equivalent is determined by taking gold ounces produced and sold, plus silver ounces produced and sold, converted to gold equivalent ounces 
using the gold to silver average realized price ratio for the period.

FORWARD-LOOKING STATEMENTS 

This report contains “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933 
and Section 21E of the Securities Exchange Act of 1934. We use the words “anticipate,” “continue,” “likely,” “estimate,”

Forward-looking statements are neither historical facts nor assurances of future performance. Rather, they are based 
only on our current beliefs, expectations, and assumptions regarding the future of our business, future plans and strategies, 
projections, anticipated events and trends, the economy, and other future conditions. Because forward-looking statements 
relate  to  the  future,  they  are  subject  to  inherent  uncertainties,  risks,  and  changes  in  circumstances  that  are  difficult  to 
predict, and many of which are outside of our control. Our actual results and financial condition may differ materially 
from those indicated in the forward-looking statements. Therefore, you should not rely on any of these forward-looking 
statements. Important factors that could cause our actual results and financial condition to differ materially from those 
indicated in the forward-looking statements include, among others, the following: 

  The extent of the impact of any pandemic, including the duration, spread, severity, and any repeated resurgence 
of  a  pandemic,  the  duration  and  scope  of  related  government  orders  and  restrictions,  the  impact  on  our 
employees, and the extent of the impact of a pandemic on our mining operations; 

  Commodity price fluctuations;  
  Mine protests and work stoppages; 
  Rock  formations,  faults  and  fractures,  water  flow,  possible  CO2  gas  exhalation,  or  other  unanticipated 

geological challenges; 

  Unexpected  changes  in  business  and  economic  conditions,  including  supply  chain  challenges,  the  rate  of 

inflation, and their impact on operating and capital costs;  

  Changes in interest rates and currency exchange rates;  
  The Company’s inability to secure financing when needed; 
  Adverse technological changes and cybersecurity threats;  
  Unanticipated increases in our operating costs and other costs of doing business;  
  Access to land and availability of materials, equipment, supplies, labor and supervision, power, and water;

Interpretation of drill hole results and the geology, grade, and continuity of mineralization;  

  Results of current and future feasibility studies;  
 
  Litigation by private parties or regulatory action by governmental entities;  
  Acts of God, such as floods, earthquakes, and any other natural disasters; 
  The uncertainty of Mineral Resource and Mineral Reserve estimates; and 
  Such other factors are discussed below under “Risk Factors”. 

Many  of  these  factors  are  beyond  our  ability  to  control  or  predict.  Although  we  believe  that  the  expectations 
reflected  in  our  forward-looking  statements  are  based  on  reasonable  assumptions,  such  expectations  may  prove  to  be 
materially incorrect due to known and unknown risks and uncertainties. You should not unduly rely on any of our forward-
looking statements. These statements speak only as of the date of this annual report on Form 10-K. Except as required by 
law, we are not obligated to publicly release any revisions to these forward-looking statements to reflect future events or 
developments. All subsequent written and oral forward-looking statements attributable to us and persons acting on our 
behalf are qualified in their entirety by the cautionary statements contained in this section and elsewhere in this annual 
report on Form 10-K.

BUSINESS 

History and Organization 

PART I 

In this report, “Company,” “GRC,” “our,” “us,” and “we” refer to Gold Resource Corporation together with its 

subsidiaries, unless the context otherwise requires. See Item 2. Properties—Glossary for additional definitions. 

Gold Resource Corporation was organized under the laws of Colorado, USA on August 24, 1998. Since 2010, GRC 
has produced gold and silver doré and copper, lead, and zinc concentrates in Oaxaca, Mexico at our subsidiary, Don David 
Gold Mexico S.A. de C.V. (“Don David Gold Mine” or “DDGM”). The Don David Gold Mine holds six (6) properties 
which are all located in what is known as the San Jose structural corridor. Our properties span 55 continuous kilometers 
of this structural corridor, which include three historic mining districts in Oaxaca. 

On  December  10,  2021,  the  Company  successfully  completed  the  acquisition  of  all  the  issued  and  outstanding 
common shares of Aquila Resources Inc (the “Aquila Transaction”). Aquila’s principal asset is its 100% interest in the 
Back  Forty  Project  located  in  Menominee  County,  Michigan,  USA.  The  Back  Forty  Project  has  a  polymetallic  (gold, 
silver, copper, lead, and zinc) Volcanogenic Massive Sulfide deposit. The Back Forty Project controls surface and mineral 
rights through ownership and leases with the State of Michigan. Optimization work related to metallurgy and the economic 
model was completed during the third quarter of 2023, and the Company filed the Back Forty Project Technical Report 
Summary on October 26, 2023. Results of the work indicate a more robust economic project with no planned impacts to 
wetlands that is more protective of the environment, which should facilitate a successful mine permitting process. The 
Board continues to evaluate options that could lead to the development of the Project. 

Review of Strategic Alternatives 

Notwithstanding the technical successes noted above, in light of the continued challenges facing the Company, the 
Company’s Board of Directors has decided to initiate a formal review process, with the assistance of outside financial and 
legal advisors, to evaluate strategic alternatives for the Company. The comprehensive process is evaluating a broad range 
of options to maximize shareholder value, including a potential sale of the Company. 

There is no deadline or definitive timetable for completion of the strategic alternatives review process, and there 
can be no assurance regarding the results or outcome of this review. The Company does not intend to comment further on 
this strategic review process until it has been completed or the Company determines that a disclosure is required by law 
or otherwise deemed appropriate.

Mexico Production Stage Properties: 

The primary production stage properties at DDGM commenced operations in 2010. The current operations include 
the Arista underground mine and the DDGM processing facility. The DDGM processing facility currently produces doré 
and metal concentrates from ore mined at the Arista Mine. The Arista Mine was expanded in 2016 with the development 
of  the  Switchback  vein  system.  The  Arista  Mine  portal  is  located  approximately  two  kilometers  from  the  processing 
facility.  Additionally,  underground  mining  at  the  Alta  Gracia  mine  was  conducted  from  2017  to  2019.  Alta  Gracia  is 
approximately 32 kilometers from the processing facilities.  

The Arista and Alta Gracia mines include a total of approximately 30,000 hectares of mining concessions, access 
roads from a major highway, haul roads, a processing facility and adjoining buildings, an assay lab, a now depleted open 
pit, underground mines, tailings facilities, and other infrastructure. Please see Item 2. Properties for additional information.  

Mexico Exploration Prospects: 

The current company land package sits within the highly prospective 55-kilometer-long San Jose structural corridor, 
in Oaxaca, Mexico. Multiple volcanic domes of various scales, and likely non-vented intrusive domes, dominate the district 
geology. These volcanogenic features are imposed on a pre-volcanic basement of sedimentary rocks. Gold and silver, as 
well as base metal mineralization in this district is related to the manifestations of this classic volcanogenic system and is 
considered epithermal in character. The Company intends to advance organic growth and to unlock the value of the mine, 
existing infrastructure, and our large property position by continuing to invest in exploration and development. Please see 
Item 2. Properties for additional information.

Back Forty Project: 

Processing Plant at Night 

There is a long history of exploration at the Back Forty Project. After acquisition of Aquila and the Back Forty 
Project  by  the  Company  in  2021,  optimization  work  was  initiated  to  address  the  mine’s  footprint,  potential  for  an 
underground mine, wetland mitigation, and other key construction and design decisions. This optimization work related 
to a change in mine design, tailings relocation, metallurgy, and the economic model was completed, and the Company 
filed the Back Forty Project Technical Report Summary on October 26, 2023. Results of the work indicate a more robust 
economic project with no planned impacts to wetlands that is more protective of the environment, which should facilitate 
a successful mine permitting process. The Board continues to evaluate options that could lead to the development of the 
Project. Please see Item 2. Properties for additional information. 

Before the Aquila Transaction, Aquila’s common shares were traded on the Toronto Stock Exchange (“TSX”) under 
the ticker symbol AQA. Effective December 10, 2021, Aquila ceased to be a reporting issuer in British Columbia, Alberta, 
Saskatchewan, Ontario, and Nova Scotia. At the same time, GRC became a reporting issuer in British Columbia, Alberta, 
Saskatchewan, Ontario, and Nova Scotia by virtue of the completion of the acquisition. As a Canadian Issuer, GRC is now 
required to file reports on the System for Electronic Document Analysis and Retrieval (“SEDAR”) in Canada. All financial 
statements filed on SEDAR will conform to United States Generally Accepted Accounting Principles (“U.S. GAAP”). 

Administrative Offices: 

Our principal executive offices are located at 7900 E. Union Ave, Suite 320, Denver, Colorado 80237, and our 
telephone number is (303) 320-7708. The Company maintains a website at www.goldresourcecorp.com. Information on

For  the  year  ended  December 31, 2023,  the  Company  reported  a  net  loss  of  $16.0  million.  The  loss  is  mainly 
attributable  to  a  high  inflationary  environment  and  the  strengthening  of  the  Mexican  Peso,  which  resulted  in  higher 
production and capital costs (including but not limited to energy, payroll, services, and equipment costs). Financial results 
for 2023 include revenue of $97.7 million and mine gross loss of $5.3 million. The Company achieved solid production 
results for the year totaling 20,328 gold ounces, 1,142,138  silver ounces, 1,287 copper tonnes, 5,068 lead tonnes, and 
13,513 zinc tonnes, as planned, despite achieving lower production than in 2022 due to mine planning. 

For  the  ninth  consecutive  year,  the  DDGM  received  the 
prestigious ESR award from the Mexican Center for Philanthropy 
(“CEMEFI”). Awards are given to organizations that demonstrate a 
commitment  to  supporting  social  and  environmental  protection 
programs within their local communities. 

Our  2023  exploration  activities  were  focused  on  drilling  at 
the Arista and Switchback vein systems in the Arista Mine. During 
the  year,  we  completed  168  underground  diamond  drill  holes 
totaling 36,350 meters, including 18 expansion drill holes totaling 
10,293 meters and 150 infill drill holes totaling 26,057 meters in the 
Arista mine. In addition to exploration drilling, 520 meters of drift 
development  was  completed  to  support  the  expansion  and  infill 
drilling programs. 

During 2023, exploration was strategically directed towards 
infill  and  expansion  drilling  of  multiple  high-grade,  polymetallic 
epithermal veins within the Switchback vein system, both up- and 
down-dip  and  along  strike  of  existing  workings,  as  well  as  in  the 
Three Sisters and newly discovered Gloria vein systems to define 
additional  Mineral  Reserves  and  Mineral  Resources.  The  Gloria 
vein system, located near existing mine infrastructure and comprised 
of no fewer than three distinct veins, is located between and north of 
the Arista and Switchback vein systems. Both the Gloria and Three 
Sisters  vein  systems  will  be  a  primary  focus  of  the  2024  drilling 
program.  The  2023  drilling  program  successfully  targeted  the 
expansion of the Arista vein system along strike to the north-west, 
with particular focus on the Splay 31 and Marena North veins, to 
define additional Mineral Resources. Surface exploration activity during 2023 focused on the Alta Gracia property with 
the interpretation of surface mapping and soil geochemistry results received late 2022. This work has identified several 
targets  for  future  follow-up  exploration  activity.  Our  continued  investment  in  exploration  efforts  demonstrate  our 
commitment to long-term investment in Oaxaca, Mexico. 

Ninth consecutive ESR award 

For the Back Forty Project, work in 2023 focused on the optimization of the mine design, project layout, metallurgy, 
and the economic model which was completed and filed by the Company in a Technical Report Summary on October 26, 
2023.  Results  of  the  work  indicate  a  more  robust  economic  project  with  no  planned  impacts  to  wetlands  that  is  more 
protective  of  the  environment,  which  should  facilitate  a  successful  mine  permitting  process.  The  Board  continues  to 
evaluate options that could lead to the development of the Project.  

In  June  2023,  the  petition  by  the  Menominee  Indian  Tribe  of  Wisconsin  (“MITW”)  to  have  an  area  along  the 
Menominee  River  registered  as  a  cultural  landscape  with  the  Keeper  of  the  National  Register  of  Historic  Places  was 

Gold Resource Corporation 
8 

 
 
 
 
 
 
approved. Anaem Omot is an area around the Menominee River known as the Sixty Islands. This area is known to have 
culturally significant archeological findings. The Company helped identify these artifacts to ensure that proper procedures 
are deployed to protect cultural resources and to avoid and mitigate intrusions to the cultural landscape, as required. In 
addition  to  identifying  these  culturally  significant  resources,  the  Company  has  incorporated  them  into  the  Back  Forty 
Project designs and permitting strategy. 

We  are  also  monitoring  the  U.S.  Army  Corps  of  Engineers’  review  of  a  petition  by  the  MITW  to  have  the 
Menominee  River  designated  as  Navigable  under  Section  10  of  the  Rivers  and  Harbor  Act.  The  MITW  asked  the 
Environmental Protection Agency and the U.S. Army Corps of Engineers’ to revisit whether they—as opposed to the state 
of Michigan—should exercise authority over Aquila’s Back Forty permit applications. In response to a petition from the 
MITW, the U.S. Army Corps of Engineers is updating its navigability study on the Menominee River, which is expected 
to be completed in 2025.

Dividends  

In  February  2023,  we  announced  the  suspension  of  our  quarterly  dividend  until  such  time  that  it  may  become 
practicable to reinstate. Please see Item 5. Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer 
Purchase of Equity Securities for additional information regarding our Dividend Policy. 

Insurance 

Our business is capital intensive and requires ongoing investment for the replacement, modernization, or expansion 
of equipment and facilities. For more information, please see Item 7. Management’s Discussion and Analysis of Financial 
Condition and Results of Operations—Liquidity and Capital Resources below. We maintain insurance policies against 
property loss and business interruption and insure against most risks that are typical in the operation of our business in 
amounts  that  we  believe  to  be  reasonable.  Such  insurance,  however,  contains  exclusions  and  limitations  on  coverage, 
particularly with respect to property loss, environmental liability, and political risk. There can be no assurance that claims 
would be paid under such insurance policies in connection with a particular event. Please see Item 1A. Risk Factors below 
for additional information. 

Competitive Business Conditions 

The acquisition of gold and silver properties is subject to intense competition. Identifying and evaluating potential 
mining prospects is a costly and time-consuming endeavor. In 2021, we successfully acquired the Back Forty Project as 
discussed  above.  We  expect  to  continue  our  significant  investment  in  exploration  and  growth  activities  in  the  future; 
however, competition for acquiring mineral prospects will continue to be intense. 

Government Regulations and Permits  

In connection with mining, milling, and exploration activities in Mexico, we are subject to Mexican federal, state, 
and local laws and regulations governing the protection of the environment, including laws and regulations relating to the 
protection  of  air  and  water  quality,  hazardous  waste  management,  mine  reclamation,  as  well  as  the  protection  of 
endangered  or  threatened  species.  The  government  department  responsible  for  environmental  protection  in  Mexico  is 
Secretaria  de  Medio  Ambiente  y  Recursos  Naturales  (“SEMARNAT”).  SEMARNAT  has  broad  authority  over 
environmental regulations and standards. Potential areas of environmental consideration for mining companies, such as 
ours, include but are not limited to acid rock drainage, cyanide containment and handling, contamination of water sources, 
dust, and noise. 

For operations at our Don David Gold Mine, we have secured and continue to maintain various regulatory permits 
from federal, state, and local agencies. These governmental and regulatory permits generally govern the processes being 
used to operate, the stipulations concerning air quality, water issues, hazardous and waste management, and the plans and 
obligations for reclamation of the properties at the conclusion of operations. These laws and regulations are continually 
changing and are generally becoming more restrictive.  

Our production stage mines in Mexico have reclamation plans in place that we believe meet all applicable legal and 
regulatory requirements. As of December 31, 2023, $11.4 million has been accrued on our Consolidated Balance Sheets 
for reclamation costs relating to our production and exploration stage properties in Mexico. In addition, we accrued $0.4 
million for drill-hole capping in Michigan. 

The  State  of  Michigan  has  been  delegated  authority  under  federal  environmental  law  to  issue  all  necessary 
environmental permits required for the Back Forty project. The State of Michigan’s “Natural Resource Environmental 
Protection Act” provides rules and regulations for the State Department of Environment, Great Lakes and Energy (EGLE) 
to issue permits for mining, treated wastewater discharge, air emissions, and related environmental permits necessary for 
the project.

Customers 

During the year ended December 31, 2023, three customers accounted for 98% of our revenue from DDGM. In the 
event that our relationship with any of the customers is interrupted for any reason, we believe that we would be able to 
locate another entity to purchase our products in a timely manner on substantially similar terms. However, any interruption 
could  temporarily  disrupt  the  sale  of  our  principal  products  and  materially  adversely  affect  our  operating  results.  We 
periodically review our options for alternative sales outlets to mitigate the concentration of risk in case of any unforeseen 
disruptions. 

Human Capital Resources 

We value excellence and recognize that embracing the diverse backgrounds, skills, and perspectives of the local 
workforce  will  lead  to  a  competitive  advantage.  We  are  committed  to  leading  by  example  and  maintaining  a  fair  and 
inclusive work environment built on mutual respect and integrity. Diversity means understanding, accepting, respecting, 
and valuing differences among people regardless of age, gender, race, ethnicity, culture, religion or spiritual practices, 
disabilities, sexual orientation, gender identity, family status, or veteran status. 

We believe we have good morale and a dedicated workforce. Our human capital resources objectives include, as 
applicable,  identifying,  recruiting,  retaining,  incentivizing,  and  integrating  our  existing  employees  and  new  hires.  The 
principal purposes of our equity incentive plans are to attract, retain, and motivate selected employees and directors by 
granting stock-based compensation awards that align employee compensation with shareholder returns. 

DDGM Employee Housing 

As  of  December  31,  2023,  the  Company  had  488  employees  at  DDGM.  There  were  16  full-time  corporate 
employees, three of whom serve as executive officers, and three full-time employees in Michigan who are fully dedicated 
to progressing the Back Forty Project.

RISK FACTORS 

Our business, and the mining industry in general, is influenced by significant risks and uncertainties. These risks 
include those described below and may include additional risks and uncertainties not presently known to us or that we 
currently  deem  immaterial.  Our  business,  financial  condition,  and  results  of  operations  could  be  materially  adversely 
affected by any of these risks, and the trading price of our common stock could decline by virtue of these risks. These risks 
should be read in conjunction with the other information in this annual report on Form 10-K. 

Financial Risks 

Our results of operations, cash flows, and the value of our properties are highly dependent on the market prices 

of gold, silver, and certain base metals, and these prices can be volatile.  

The profitability of our mining operations and the value of our mining properties are directly related to the market 
price of gold, silver, copper, lead, and zinc. The price of gold and silver may also significantly influence the market price 
of our  common  stock.  The market  prices of  these  metals  historically  have  fluctuated significantly  and  are  affected  by 
numerous factors beyond our control, including (i) global or regional consumption patterns; (ii) supply of and demand for 
silver and gold on a worldwide basis; (iii) speculative and hedging activities; (iv) expectations for inflation; (v) political 
and economic conditions; (vi) supply of, and demand for, consumables required for extraction and processing of metals, 
and (vii) general economic conditions worldwide. Over the last five years (as reported on the London Bullion Market 
Association using the London PM Fix for gold and silver), gold prices have fluctuated from a low of $1,270 per ounce to 
a high of $2,078 per ounce, and silver prices have fluctuated from a low of $12.01 per ounce to a high of $29.59 per ounce. 
On December 28, 2023, The London PM Fix gold price was $2,078 per ounce and on December 29, 2023, the London PM 
silver price was $23.79 per ounce.  

Currently, we do not use hedging transactions with respect to any of our metal production. Accordingly, we are 
fully exposed to price fluctuations in precious metals. In the event metal prices decline or remain low for prolonged periods 
of time, we might be unable to develop our exploration properties, which may materially adversely affect our results of 
operations,  financial  performance,  and  cash  flows.  An  asset  impairment  charge  may  result  from  the  occurrence  of 
unexpected adverse events that impact our estimates of expected cash flows generated from our mining operations or the 
market value of our non-producing properties, including a material diminution in the price of metals.  

We may not achieve profitability. 

Our DDGM property is the only property we own that produces revenue, and it may not generate sufficient cash 
flow  to  cover  our  operating,  development,  exploration,  general  and  administrative,  and  other  costs  due  to  certain  risk 
factors. Unexpected interruptions in our mining business may cause us to incur losses, or the revenue that we generate 
from extraction may not be sufficient to fund continuing operations, including exploration and mine development costs. 
Our failure to generate future profits may materially adversely affect the price of our common stock, and stockholders may 
lose all or part of their investment. Metal prices and foreign currency rates have a significant impact on our profit margin, 
and there is no assurance that we will be profitable in the future. Please see Item 1A. Risk Factors—General Risks – Our 
results of operations, cash flows, and the value of our properties are highly dependent on the market prices of gold, silver, 
and certain base metals and these prices can be volatile. 

We may not have access to sufficient future capital. 

We may be required to expend significant funds to develop, access, and determine if Mineral Reserves exist at any 
of our non-producing properties, continue exploration, and if warranted, develop our existing properties and identify and 
acquire additional properties to diversify our property portfolio.  

Our  ability  to obtain necessary  funding for  these purposes,  in  turn, depends upon  several factors,  including our 
historical and prospective results of operations, the status of the national and worldwide economy, the price of gold, silver, 

Gold Resource Corporation 
12 

 
 
 
 
and other metals, the condition of the debt and equity markets, the costs associated with extracting and acquiring minerals, 
and the market value for our common stock. We may not be successful in generating or obtaining the required financing, 
or if we can obtain such financing, such financing may not be on terms that are favorable to us and our shareholders. We 
also may be unable to obtain funding by monetizing additional non-core exploration or other assets at an acceptable price. 

We cannot provide assurance we will be able to obtain financing to fund our general and administrative costs and 
other working capital needs to fund our continuing business activities in the future on favorable terms or at all. Failure to 
obtain  financing  could  result  in  delay  or  indefinite  postponement  of  further  mining  operations,  exploration,  and 
construction, as well as the possible partial or total loss of our interest in our properties. 

Our ability to recognize the benefits of deferred tax assets is dependent on future cash flows and taxable income. 

We recognize deferred tax assets when the tax benefit is more likely than not to be realized; otherwise, a valuation 
allowance is applied against deferred tax assets. Assessing the recoverability of deferred tax assets requires management 
to make significant estimates related to expectations of future taxable income. Estimates of future taxable income are based 
on forecasted cash flows from operations and the application of existing tax laws in each jurisdiction. To the extent that 
future cash flows and taxable income differ significantly from estimates, our ability to realize the deferred tax assets could 
be impacted. Additionally, future changes in tax laws could limit our ability to realize the future tax benefits represented 
by our deferred tax assets. 

Our accounting and other estimates may be imprecise. 

Preparing financial statements requires management to make estimates and assumptions that affect the reported 
amounts  and  related  disclosure  of  assets,  liabilities,  revenue,  and  expenses  at  the  date  of  the  consolidated  financial 
statements and reporting periods. The more significant areas requiring the use of management assumptions and estimates 
relate to: 

  Mineral Resources that are the basis for future income and cash flow estimates; 
  Mineral  Reserves  that  are  the  basis  for  units-of-production  depreciation,  depletion,  and  amortization 

calculations; 

  Future ore grades, throughput, and recoveries; 
  Future metals prices; 
  Future capital and operating costs; 
  Environmental, reclamation, and closure obligations;  
  Gold and Silver Stream Agreements; 
  Contingent Consideration Liabilities; 
  Permitting and other regulatory considerations; 
  Asset impairments; 
  The valuation of our investments in equity securities; 
  Asset acquisition accounting, including the valuation of the transaction and related instruments; 
  Future foreign exchange rates, inflation rates, and applicable tax rates; and 
  Deferred tax asset valuation allowance. 

Future  estimates  and  actual  results  may  differ  materially  from  these  estimates  as  a  result  of  using  different 
assumptions or conditions. For additional information, see Item 7. Management’s Discussion and Analysis of Financial 
Condition and Results of Operations. 

We may be required to repay a significant amount if we default under certain gold and silver stream agreements. 

In connection with the Aquila Transaction, the Company assumed substantial liabilities related to the gold and silver 
stream agreements with Osisko Bermuda Limited (“Osisko”). Under the agreements, Osisko deposited a total of $37.2 
million upfront in exchange for a portion of the future gold and silver production from the Back Forty Project. The stream 

Gold Resource Corporation 
13 

 
 
 
 
agreements contain customary provisions regarding default and security. In the event that our subsidiary defaults under 
the stream agreements, including by failing to achieve commercial production by an agreed upon date, it may be required 
to repay the deposit plus accumulated interest at a rate agreed with Osisko. If the Company fails to do so, Osisko may elect 
to enforce its remedies as a secured party and take possession of the assets that comprise the Back Forty Project. 

Operational Risks 

Our  production  is  derived  from  a  single  operating  unit,  and  any  interruptions  or  stoppages  in  our  mining 

activities at that operating unit would materially adversely affect our revenue. 

We are dependent on revenues from a single operating unit to fund our operations. Any interruption in our ability 
to mine this location, such as a labor strike, natural disaster, or loss of permits would negatively impact our ability to 
generate revenue following such interruption. Additionally, if we are unable to develop additional mines economically, 
we will eventually deplete the body of mineralized material and will no longer generate cash flow sufficient to fund our 
operations. A decrease in, or cessation of, our mining operations at this operating unit would materially adversely affect 
our financial performance and may eventually cause us to cease operations. 

Since our current property portfolio is limited to one operating unit, our ability to be profitable over the long-
term will depend on our ability to (1) expand the known Arista and Switchback vein systems and /or identify, explore, 
and develop additional properties in Mexico, (2) successfully develop the Back Forty Project in Michigan, USA, or (3) 
acquire and develop an alternative project.  

Gold and silver producers must continually replace reserves depleted by production to maintain production levels 
over the long-term and provide a return on invested capital. Depleted reserves can be replaced in several ways, including 
expanding known ore bodies, locating new deposits, or acquiring interests in reserves from third parties. Exploration is 
highly speculative in nature, capital intensive, involves many risks, and frequently unproductive. Our current or future 
exploration programs may not result in new mineralization. Even if significant mineralization is discovered, it will likely 
take many years from the initial phases of exploration until commencement of production, during which time the economic 
feasibility of production may change. 

From time to time, we may acquire mineral interests from other parties. Such acquisitions are based on an analysis 
of  a  variety  of  factors,  including  historical  exploration  results,  estimates  and  assumptions  regarding  the  extent  of 
mineralized material and/or reserves, the timing of production from such reserves, and cash and other operating costs. In 
addition, we may rely on data and reports prepared by third parties, which may contain information or data that we are 
unable to independently verify or confirm. All of these factors are uncertain and may impact our ability to develop the 
mineral interests. 

As a result of these uncertainties, our exploration programs and any acquisitions which we may pursue may not 
result in the expansion or replacement of our current production with new ore reserves or operations, which could have a 
material adverse effect on our business, prospects, results of operations, and financial position.  

Gold Resource Corporation 
14 

 
 
 
 
Increased operating and capital costs could materially adversely affect our results of operations.  

Costs at our mining properties are subject to fluctuation due to a number of factors, such as variable ore grade, 
changing metallurgy, and revisions to mine plans in response to the physical shape and location of the ore body, as well 
as the age and utilization rates for the mining and processing-related facilities and equipment. In addition, costs are affected 
by the price and availability of input commodities, such as fuel, electricity, labor, chemical reagents, explosives, steel, 
concrete, and mining and processing related equipment and facilities. Commodity costs are often subject to volatile price 
movements,  including  increases  that  could  make  mineral  extraction  less  profitable.  Further,  changes  in  laws  and 
regulations can affect commodity prices, uses, and transport. Reported costs may also be affected by changes in accounting 
standards. A material increase in costs could significantly affect our results of operations and operating cash flow. 

We could have significant increases in capital and operating costs over the next several years in connection with 
developing  new  projects  in  challenging  jurisdictions  and  sustaining  and/or  expanding  existing  mining  and  processing 
operations. Costs associated with capital expenditures may increase in the future as a result of factors beyond our control, 
such as inflation. Increased capital expenditures may have an adverse effect on the results of operations and cash flow 
generated  from  existing  operations,  as  well  as  the  economic  returns  anticipated  from  new  projects,  or  may  make  the 
development of future projects uneconomic. 

Competition in the mining industry is intense, and we have limited financial and personnel resources with which 

to compete. 

In  the  mining  industry,  competition  for  desirable  properties,  investment  capital,  and  human  capital  is  intense. 
Numerous  companies  headquartered  in  the  United  States,  Canada,  and  worldwide  compete  for  properties  and  human 
capital on a global basis. We are a small participant in the mining industry due to our limited financial and human capital 
resources. We presently operate with a limited number of people, and we anticipate operating in the same manner going 
forward. We compete with other companies in our industry to hire qualified employees and consultants when needed to 
operate our mines successfully and to advance our exploration properties. We may be unable to attract the necessary human 
capital to fully explore, and if warranted, develop our properties and be unable to acquire other desirable properties. We 
believe that competition for acquiring mineral properties, as well as the competition to attract and retain qualified human 
capital, will continue to be intense in the future. 

Estimates  of  proven  and  probable  Mineral  Reserves  and  measured  and  indicated  Mineral  Resources  are 

uncertain, and the volume and grade of ore actually recovered may vary from our estimates.  

The proven and probable Mineral Reserves stated in this report represent the amount of gold, silver, copper, lead, 
and zinc that we estimated at December 31, 2023, that could be economically and legally extracted or produced at the time 
of the reserve determination. Estimates of proven and probable Mineral Reserves and measured and indicated Mineral 
Resources are subject to considerable uncertainty. Such estimates are largely based on the prices of gold, silver, copper, 
lead, and zinc, as well as interpretations of geologic data obtained from drill holes and other exploration techniques. These 
prices and interpretations are subject to change. If we determine that certain of our estimated Mineral Reserves or Mineral 
Resources  have  become  uneconomic,  we  may  be  forced  to  reduce  our  estimates.  Actual  production  from  proven  and 
probable Mineral Reserves may be significantly less than we expect. There can be no assurance that estimates of Mineral 
Resources will be upgraded to Mineral Reserves or may ultimately be extracted.  

Any material changes in Mineral Reserve or Mineral Resource estimates and grades of mineralization may affect 
the  economic  viability  of  our  current  operations,  our  decision  to  place  a  new  property  into  production,  and/or  such 
property’s  return  on  capital.  There  can  be  no  assurance  that  mineral  recoveries  in  small-scale  laboratory  tests  will  be 
duplicated in a large-scale on-site operation in a production environment. Declines in market prices for contained metals 
may render portions of our Mineral Reserve or Mineral Resource estimates uneconomic and result in reduced reported 
mineralization  or  materially  adversely  affect  the  commercial  viability  of  one  or  more  of  our  properties.  Any  material 
reductions in estimates of mineralization, or of our ability to extract this mineralization, could have a material adverse 
effect on our results of operations or financial condition. 

Gold Resource Corporation

Products processed from our operating mines or other mines in the future could contain higher than expected 

contaminants, thereby negatively impacting our financial condition. 

Contracts for treatment charges paid to smelters and refineries include penalties for certain deleterious elements that 
exceed contract limits. If the material mined from our operating mines includes higher than expected contaminants, this 
will  result  in  higher  treatment  expenses  and  penalty  charges  that  could  increase  our  costs  and  negatively  impact  our 
business, financial condition, and results of operations. This could occur due to unexpected variations in the occurrence of 
these elements in the material mined, problems that occur during blending of material from various locations in the mine 
prior to processing, and other unanticipated events. 

Continuation of our mining and processing activities is dependent on the availability of sufficient water supplies 

to support our mining activities. 

Water is critical to our business, and the increasing pressure on water resources requires us to consider both current 
and future conditions in our management approach. Across the globe, water is a shared and regulated resource. Mining 
operations require significant quantities of water for mining, ore processing, and related support facilities. Many of our 
properties in Mexico are in areas where water is scarce, and competition among users for continuing access to water is 
significant. Continuous production and mine development depend on our ability to acquire and maintain water rights and 
defeat claims adverse to current water use in legal proceedings. Although we believe that our operations currently have 
sufficient water rights and claims to cover operating demands, we cannot predict the potential outcome of future legal 
proceedings relating to water rights, claims, and uses. Water shortages may also result from weather or environmental and 
climate impacts beyond our control. Shortages in water supply could result in production and processing interruptions. In 
addition, the scarcity of water in certain regions could result in increased costs to obtain sufficient quantities of water to 
conduct our operations. The loss of some or all water rights, in whole or in part, ongoing shortages of water to which we 
have  rights,  or  significantly  higher  costs  to  obtain  sufficient  quantities  of  water  (or  the  failure  to  procure  sufficient 
quantities of water) could result in our inability to maintain mineral extraction at current or expected levels, require us to 
curtail or shut down mining operations, and prevent us from pursuing expansion or any development opportunities. Laws 
and regulations may be introduced in some jurisdictions where we operate, which could also limit access to sufficient 
water resources, thus materially adversely affecting our operations. 

The nature of mineral exploration, mining, and processing activities involves significant hazards, a high degree 

of risk, and the possibility of uninsured losses. 

Exploration  for  and  the  production  of  minerals  is  highly  speculative  and  involves  greater  risk  than  many  other 
businesses. Many exploration programs do not result in the discovery of mineralization, and any mineralization discovered 
may not be of sufficient quantity or quality to be profitably mined. Our operations are, and any future mining operations 
or construction we may conduct will be, subject to all of the operating hazards and risks normally incident to exploring for 
and mining of mineral properties, such as, but not limited to: 

  Fluctuation in production costs that make mining uneconomic; 
  Fluctuation in commodity prices; 
  Social,  community,  or  labor  force  disputes  resulting  in  work  stoppages  or  delays,  or  related  loss  of  social 

acceptance of community support; 

  Changes to legal and regulatory requirements;  
  Unanticipated variations in grade and other geologic problems; 
  Environmental hazards, noxious fumes, and gases; 
  Ground and water conditions; 
  Difficult surface or underground conditions; 
 
Industrial accidents; 
  Security incidents;  
  Failure of unproven or evolving technologies or loss of information integrity or data;  
  Metallurgical and other processing problems;

  Mechanical and equipment performance problems; 
  Failure of pit walls, dams, declines, drifts, and shafts; 
  Unusual or unexpected rock formations; 
  Personal injury; 
  Pandemics; 
  Fire, flooding, cave-ins, seismic activity, landslides, or other inclement weather conditions, including those 

impacting operations or the ability to access and supply sites; and 

  Decrease in the value of mineralized material due to lower gold, silver, and metal prices. 

These  occurrences  could  result  in  damage  to—or  destruction  of—mineral  properties,  processing  facilities,  and 
equipment; personal injury or death; environmental damage; reduced extraction and processing; delays in mining; asset 
write-downs; monetary losses; and possible legal liability. Although we maintain insurance in amounts that we consider 
reasonable for general commercial liability claims, physical assets at our Arista and Alta Gracia mines, and risks inherent 
in  the  conduct  of  our  business,  this  insurance  contains  exclusions  and  limitations  on  coverage  and  will  not  cover  all 
potential risks associated with mining and exploration activities. As such, the related liabilities might exceed policy limits. 
As a result of any or all of the foregoing, we could incur significant liabilities and costs that may exceed the limits of our 
insurance coverage or that we may elect not to insure against because of premium costs or other reasons, which could 
materially  adversely  affect  our  results  of  operations  and  financial  condition.  We  may  also  not  be  insured  against  all 
interruptions to our operations. Losses from these or other events may cause us to incur significant costs which could 
materially adversely affect our financial condition and our ability to fund activities on our properties. A significant loss 
could force us to reduce or suspend our operations and development. 

Revenue  from  the  sale  of  metal  concentrate  may  be  materially  adversely  affected  by  loss  or  damage  during 

shipment and storage at our buyer’s facilities. 

We  rely  on  third-party  transportation  companies  to  transport  our  metal  concentrate  to  the  buyer’s  facilities  for 
processing and further refining. The terms of our sales contracts with the buyers require us to rely, in part, on assay results 
from samples of our metal concentrate that are obtained at the buyer’s warehouse to determine the final sales value for our 
metals. Once the metal concentrate leaves our processing facility, we no longer have direct custody and control of these 
products. Theft, loss, road accidents, improper storage, fire, natural disasters, tampering, or other unexpected events while 
in transit or at the buyer’s location may lead to the loss of all or a portion of our metal concentrate products. Such losses 
may not be covered by insurance and may lead to a delay or interruption in our revenue, and as a result, our operating 
results may be materially adversely affected. 

A  significant delay  or  disruption  in  sales of  doré  or  concentrates as a  result of  the unexpected disruption  in 

services provided by smelters or refiners could have a material adverse effect on results of operations.  

We rely on third-party smelters and refiners to refine and process and, in some cases, purchase, the gold and silver 
doré and copper, lead, and zinc concentrate produced from our mines. Access to smelters and refiners on economic terms 
is critical to our ability to sell our products to buyers and generate revenues. We periodically enter into agreements with 
smelters and refiners, some of which operate their smelting or refining facilities outside the United States, and we believe 
we currently have contractual arrangements with a sufficient number of smelters and refiners so that the loss of any one 
refiner  or  smelter  would  not  significantly  or  materially  impact  our  operations  or  our  ability  to  generate  revenues. 
Nevertheless, services provided by a refiner or smelter may be disrupted by operational issues, new or increased tariffs, 
duties or other cross-border trade barriers, the bankruptcy or insolvency of one or more smelters, or refiners or the inability 
to agree on acceptable commercial or legal terms with a refiner or smelter. Such an event or events may disrupt an existing 
relationship with a refiner or smelter, or result in the inability to create a contractual relationship with a refiner or smelter, 
which may leave us with limited, uneconomical, or no access to smelting or refining services for short or long periods of 
time. Any such delay or loss of access may significantly impact our ability to sell doré and concentrate products. We 
cannot ensure that alternative smelters or refiners would be available or offer comparable terms if the need for them arose 
or  that  we  would  not  experience  delays  or  disruptions  in  sales  that  would  materially  adversely  affect  the  results  of 
operations. 

Gold Resource Corporation

We  rely  on  contractors  to  conduct  a  significant  portion  of  our  exploration,  development,  and  construction 

projects.  

A significant portion of our development and construction projects are currently conducted in whole or in part by 
contractors. As a result, our operations are subject to a number of risks, some of which are outside our control, including: 

  Negotiating agreements with contractors on acceptable terms; 
  New foreign or domestic legislation limiting or altering the ability to utilize contractors or outsourced resources;  
  The  difficulty  and  inherent  delay  in  replacing  a  contractor  and  its  equipment  in  the  event  that  either  party 

terminates the agreement; 

  Reduced control and oversight over those aspects of the work which are the responsibility of the contractor; 
  Failure of a contractor to perform under its agreement; 
 

Interruption of development and construction or increased costs in the event that a contractor ceases its business 
due to insolvency or other unforeseen events; 
 
Injuries or fatalities on the job as a result of the failure to implement or follow adequate safety measures; 
  Failure  of  a  contractor  to  comply  with  applicable  legal  and  regulatory  requirements,  to  the  extent  it  is 

responsible for such compliance; and 

  Problems of a contractor managing its workforce, labor unrest, or other related employment issues. 

In addition, we may incur liability to third parties as a result of the actions of our contractors. The occurrence of 

one or more of these risks could materially adversely affect our results of operations and financial position. 

Risks Related to our Exploration Activities 

The exploration of our mineral properties is highly speculative in nature, involves substantial expenditures, and 

is frequently non-productive. 

Mineral  exploration  is highly  speculative  in  nature  and  frequently  results  in  no  or very little  return on  amounts 
invested in evaluating a particular property. The probability of an individual prospect ever having Mineral Reserves that 
meets the requirements of S-K 1300 is low. Even if we do eventually discover Mineral Reserves or Mineral Resources on 
our exploration properties, there can be no assurance that we can develop a mine and extract those minerals. Substantial 
expenditures are required to (i) establish the existence of a potential ore body through drilling and metallurgical and other 
testing techniques; (ii) determine metal content and metallurgical recovery processes to process metal from the ore; (iii) 
determine  the  feasibility  of  mine  development  and  production;  and  (iv)  construct,  renovate  or  expand  mining  and 
processing facilities. If we discover a deposit or ore at a property, it usually takes several years from the initial phases of 
exploration until mineral extraction is possible, if at all. During this time, the economic feasibility of a project may change 
because of increased costs, lower metal prices, or other factors. As a result of these uncertainties, our exploration programs 
may not result in the identification of proven and probable Mineral Reserves in sufficient quantities to justify developing 
a particular property. 

We  have  and  may  in  the  future  acquire  additional  mining  properties;  and  our  business  may  be  negatively 
impacted if Mineral Reserves are not located on acquired properties or if we are unable to successfully execute and/or 
integrate the acquisitions. 

We have in the past, and may in the future, acquire additional mining properties. There can be no assurance that 
reserves will be identified on any properties that we acquire. We may experience negative impacts on the trading price of 
our common stock or on our ability to access capital if we successfully complete acquisitions of additional properties and 
reserves are not located on these properties.  

In December 2021, we acquired the Back Forty Project when we purchased Aquila Resources Inc. The acquisition 
may result in various material adverse impacts on our business and the trading price of our common stock. Adverse impacts 
may  include,  without  limitation,  the  risk  that  the  acquisition  does  not  achieve  the  expected  benefits,  increased  cash 

Gold Resource Corporation 
18 

 
 
 
 
 
outflows, the unavailability of capital to develop the project, and the risk of potential material adverse tax consequences 
for  our  company  and  shareholders.  Additional  risks,  difficulties,  and  uncertainties  may  result  from  the  separation  of 
previously co-mingled businesses, including necessary ongoing relationships. While we have invested significant time, 
money,  and  equity  in  acquiring  the  Back Forty  Project,  there  can  be  no  assurance  that  the  Back  Forty  Project will  be 
permitted or will ultimately be productive.  

The success of any future acquisition would depend on a number of factors, including, but not limited to: 

 
Identifying suitable candidates for acquisition and negotiating acceptable terms; 
  Obtaining approval from regulatory authorities and potentially our shareholders; 
 

Implementing our standards, controls, procedures, and policies at the acquired business and addressing any 
pre-existing liabilities or claims involving the acquired business; and 

  To the extent the acquired operations are in a country where we have not operated historically, understanding 

the regulations and challenges of operating in that new jurisdiction. 

There can be no assurance that we will be able to successfully conclude any acquisitions, or that any acquisition 
will achieve the anticipated synergies or other anticipated positive results. Any material problems that we encounter in 
connection  with  such  an  acquisition  could  have  a  material  adverse  effect  on  our  business,  results  of  operations,  and 
financial position. These factors may materially adversely affect the trading price of our common stock. 

Regulatory Risks 

Our operations are subject to ongoing permitting requirements, which could result in the delay, suspension, or 

termination of our operations. 

Our operations,  including our  ongoing  exploration drilling  programs  and  mining,  require  ongoing  permits  from 
governmental  and  local  authorities.  We  may  also  be  required  to  obtain  certain  property  rights  to  access  or  use  our 
properties. Obtaining or renewing licenses and permits, and acquiring property rights, can be complex and time-consuming 
processes. There can be no assurance that we will be able to acquire all required licenses, permits, or property rights on 
reasonable terms or in a timely manner, or at all, and that such terms will not be adversely changed; that required extensions 
will be granted; or that the issuance of such licenses, permits or property rights will not be challenged by third parties. If 
we cannot obtain or maintain the necessary permits, or if there is a delay in receiving future permits, our timetable and 
business plan will be materially adversely affected. 

Our  operating  properties  located  in  Mexico  are  subject  to  changes  in  political  or  economic  conditions  and 

regulations in that country. 

The  risks  with  respect  to  operating  in  Mexico  or  other  developing  countries  include,  but  are  not  limited  to: 
nationalization of properties, military repression, extreme fluctuations in currency exchange rates, increased security risks, 
labor  instability  or  militancy,  mineral  title  irregularities,  and  high  rates  of  inflation.  In  addition,  changes  in  mining  or 
investment policies or shifts in political attitudes in Mexico may materially adversely affect our business. We may be 
affected in varying degrees by government regulation concerning restrictions on production, price controls, export controls, 
income taxes, expropriation of property, maintenance of claims, environmental legislation, land use, land claims of local 
people, opposition from non-governmental organizations, labor legislation, water use, and mine safety. The effect of these 
factors cannot be accurately predicted and may adversely impact our operations. 

Most  of  our  properties  are  subject  to  extensive  environmental  laws  and  regulations,  which  could  materially 

adversely affect our business. 

Our exploration and mining operations are subject to extensive laws and regulations governing land use and the 
protection of the environment, which control the exploration and mining of mineral properties and their effects on the 
environment, including air and water quality, mine reclamation, waste generation, handling and disposal, the protection of 
different species of flora and fauna, and the preservation of lands. These laws and regulations require us to acquire permits 
and  other  authorizations  for  conducting  certain  activities.  In  many  countries,  there  is  relatively  new  comprehensive 

Gold Resource Corporation 
19 

 
 
 
 
 
environmental legislation, and the permitting and the authorization process may not be established or predictable. We may 
not be able to acquire necessary permits or authorizations on a timely basis, if at all. Delays in acquiring any permit or 
authorization could increase the cost of our projects and could suspend or delay the commencement of extraction and 
processing of mineralized material. 

Environmental legislation in Mexico and in many other countries is evolving in a manner that will require stricter 
standards and enforcement, increased fines and penalties for non-compliance, more stringent environmental assessments 
of proposed projects, and a heightened degree of responsibility for companies and their officers, directors, and employees. 
Future changes in environmental regulation in the jurisdictions where our properties are located may materially adversely 
affect  our  business,  make  our  business  prohibitively  expensive,  or  prohibit  it  altogether.  We  cannot  predict  what 
environmental legislation or regulations will be enacted or adopted in the future or how future laws and regulations will 
be administered or interpreted. Compliance with more stringent laws and regulations, as well as potentially more vigorous 
enforcement policies or regulatory agencies or stricter interpretation of existing laws, may (i) necessitate significant capital 
outlays, (ii) cause us to delay, terminate, or otherwise change our intended activities with respect to one or more projects, 
or (iii) materially adversely affect our future exploration activities. 

Climate change and climate change legislation or regulations could impact our business.  

We  are  subject  to  physical  risks  associated  with  climate  change,  which  could  seriously  harm  our  results  of 
operations and increase our costs and expenses. The occurrence of severe adverse weather conditions, including increased 
temperatures and droughts, fires, longer wet or dry seasons, increased precipitation, floods, hail, snow, or more severe 
storms may have a potentially devastating impact on our operations. Adverse weather may result in physical damage to 
our operations, instability of our infrastructure and equipment, washed-out roads to our properties, and altered water and 
electricity supply to our projects. Increased temperatures may also decrease worker productivity at our projects and raise 
ventilation and cooling costs. Should the impacts of climate change be material in nature or occur for lengthy periods of 
time  in  the  areas  in  which  we  operate,  our  financial  condition  or  results  of  operations  could  be  materially  adversely 
affected. 

Changes in the quantity of water, whether in excess or deficient amounts, may impact exploration and development 
activities, mining and processing operations, water storage and treatment facilities, tailings storage facilities, closure and 
reclamation  efforts,  and  may  increase  levels  of  dust  in  dry  conditions,  and  land  erosion  and  slope  stability  in  case  of 
prolonged  wet  conditions.  Increased  precipitation  and  extreme  rainfall  events  may  potentially  impact  tailings  storage 
facilities by flooding the water management infrastructure, exceeding surface water runoff network capacity, overtopping 
the facility, or undermining the slope stability of the structure. Further, increased amounts of water may result in extended 
periods of flooding to the mine pits and site infrastructure or may exceed the current water treatment facility capacity to 
store and treat water physical conditions, resulting in an unintended overflow either on or off the mine site property. 

U.S. and international legislative and regulatory actions intended to ensure the protection of the environment are 
constantly changing and evolving in a manner expected to result in stricter standards and enforcement, larger fines and 
liability, and potentially increased capital expenditures and operating costs. Transitioning our business to meet regulatory, 
societal, and investor expectations may cause us to incur higher costs and lower economic returns than originally estimated 
for new exploration projects and development plans of existing operations. 

Our continuing reclamation obligations at our operations could require significant additional expenditures. 

We are responsible for the reclamation obligations related to disturbances located on all of our properties and have 
recorded a liability on our Consolidated Balance Sheets to cover the estimated reclamation obligation. However, there is 
a  risk  that  any  reserve  could  be  inadequate  to  cover  the  actual  costs  of  reclamation  when  carried  out.  Continuing 
reclamation obligations will require a significant amount of capital. There is a risk that we will be unable to fund these 
obligations and that the regulatory authorities may increase reclamation requirements to such a degree that it would not be 
commercially reasonable to continue mining and exploration activities, which may materially adversely affect our results 
of operations, financial performance, and cash flows.

Title to mineral properties can be uncertain, and in the event of a dispute regarding the title to our Mexican 
properties, it will likely be necessary for us to resolve the dispute in Mexico, where we would be faced with unfamiliar 
laws and procedures. 

Our ability to explore and operate our properties depends on the validity of our title to that property. Uncertainties 
inherent in mineral properties relate to such things as the sufficiency of mineral discovery, proper posting and marking of 
boundaries, assessment work and possible conflicts with other claims not determinable from public record. There may be 
valid  challenges  to  the  title  to  our  properties  which,  if  successful,  could  impair  development  and/or  operations.  The 
resolution of disputes in foreign countries can be costly and time consuming. In a foreign country, we face the additional 
burden of understanding unfamiliar laws and procedures. Not like in the U.S., we may not be entitled to a jury trial. Further, 
to litigate in any foreign country, we would be faced with the necessity of hiring lawyers and other professionals who are 
familiar with the foreign laws. For these reasons, we may incur unforeseen costs if we are forced to resolve a dispute in 
Mexico or any other foreign country. 

In most of the countries where we operate, failure to comply with applicable laws and regulations relating to mineral 
right applications and tenure could result in loss, reduction or expropriation of entitlements, or the imposition of additional 
local or foreign parties as joint venture partners. Any such loss, reduction, or imposition of partners could have a material 
adverse effect on our financial condition, results of operations, and prospects. 

Under the laws of Mexico, Mineral Resources belong to the United States of Mexico, and government concessions 
are required to explore for or exploit Mineral Reserves. Mineral rights derive from concessions granted, on a discretionary 
basis, by the Ministry of Economy, pursuant to the Mexican mining law and regulations thereunder. Our concessions in 
Mexico  are  subject  to  continuing  government  regulation,  and  failure  to  adhere  to  such  regulations  will  result  in  the 
termination of the concession. A title defect could result in losing all or a portion of our right, title, and interest in and to 
the properties to which the title defect relates. 

Additionally, in 2014, new mining concessions became subject to additional review and approval by the Mexico 

Ministry of Energy, and in recent years, the federal government has been reluctant to issue new mining concessions. 

Mining  concessions  in  Mexico  give  exclusive  exploration  and  exploitation  rights  to  the  minerals  located  in  the 
concessions  but  do  not  include  surface  rights  to  the  real  property,  which  requires  that  we  negotiate  the  necessary 
agreements with surface landowners. Many of our mining properties are subject to the Mexican Ejido system, requiring 
us to contract with the local communities surrounding the properties in order to obtain surface rights to land needed in 
connection with our mining exploration activities. Please see Item 1A. Risk Factors—Regulatory Risks—Our ability to 
develop our Mexican properties is subject to the rights of the Ejido (agrarian cooperatives) who use or own the surface 
for agricultural purposes. 

Our ability to develop our Mexican properties is subject to the rights of the Ejido (agrarian cooperatives), who 

use or own the surface for agricultural purposes. 

Our ability to mine minerals is subject to maintaining satisfactory arrangements and relationships with the Ejido for 
access and surface disturbances. Ejidos are groups of local inhabitants who were granted rights to conduct agricultural 
activities  on  the  property.  We  must negotiate  and  maintain  a  satisfactory  arrangement  with  these residents  in order  to 
disturb or discontinue their rights to farm. While we have successfully negotiated and signed such agreements related to 
the DDGM operations, our inability to maintain these agreements or consummate similar agreements for new projects 
could impair or impede our ability to successfully explore, develop, and mine the properties, which in turn could materially 
adversely affect our future cash flow. 

A significant amount of our mining properties are subject to exchange control policies, the effects of inflation, 

and currency fluctuations between the U.S. dollar and the Mexican peso. 

 Our revenue and external funding are primarily denominated in U.S. dollars. However, certain mining, processing, 
maintenance, and exploration costs are denominated in Mexican pesos. These costs principally include electricity, labor, 
water, maintenance, local contractors, and fuel. The appreciation of the peso against the U.S. dollar increases expenses 
and the cost of purchasing capital assets in U.S. dollar terms in Mexico, which can adversely impact our operating results 

Gold Resource Corporation 
21 

 
 
 
 
and cash flows. Conversely, the depreciation of the Mexican peso decreases operating costs and capital asset purchases in 
U.S.  dollar  terms.  When  inflation  in  Mexico  increases  without  a  corresponding  devaluation  of  the  Mexican  peso,  our 
financial position, results of operations, and cash flows could be materially adversely affected. The annual average inflation 
rate in Mexico was approximately 5.55% in 2023 and 7.89% in 2022. Current and future inflationary effects may be driven 
by, among other things, supply chain disruptions, governmental stimulus or fiscal policies, and geopolitical instability, 
including the ongoing conflicts between Ukraine and Russia and in Gaza. For additional information, please see Item 1A. 
Risk  Factors—General  Risks—The  Israel-Palestinian  conflict  in  Gaza,  the  conflict  in  Ukraine,  and  the  related  price 
volatility and geopolitical instability could negatively impact our business. Continuing increases in inflation could increase 
our costs of labor and other costs related to our business, which could have an adverse impact on our business, financial 
position, results of operations, and cash flows.  

At the same time, the peso has been subject to fluctuation, which may not have been proportionate to the inflation 
rate and may not be proportional to the inflation rate in the future. The value of the peso increased by 14.6% in 2023 and 
increased  by  6.3%  in 2022.  In  addition, fluctuations  in  currency  exchange rates  may have  a  significant  impact on our 
financial results. There can be no assurance that the Mexican government will maintain its current policies with regard to 
the  peso  or  that  the  peso's  value  will  not  fluctuate  significantly  in  the  future.  We  cannot  assure  you  that  currency 
fluctuations, inflation, and exchange control policies will not have an adverse impact on our financial condition, results of 
operations, earnings, and cash flows. 

Lack of infrastructure could forestall or prevent further exploration and advancement. 

Exploration activities, as well as any advancement activities, depend on adequate infrastructure. Reliable roads, 
bridges, power sources, and water supply are important factors that affect capital and operating costs and the feasibility 
and  economic  viability  of  a  project.  Unanticipated  or  higher  than  expected  costs  and  unusual  or  infrequent  weather 
phenomena, or government or other interference in the maintenance or provision of such infrastructure, could materially 
adversely affect our business, financial condition, and results of operations. 

Risks Related to our Common Stock 

Our stock price may be volatile, and as a result, shareholders could lose part or all of their investment. 

In addition to other risk factors identified in this annual report on Form 10-K, and due to volatility associated with 
equity securities in general, the value of a shareholder’s investment could decline due to the impact of numerous factors 
upon the market price of our common stock, including: 

  Changes in the worldwide price for the metals we mine; 
  Adverse results from our exploration, development, or production efforts; 
  Changes to the dividend program, including suspensions; 
  Producing at rates lower than those targeted; 
  Political and regulatory risks and social unrest, including the conflicts between Ukraine and Russia and in Gaza; 
  Weather conditions and extreme weather events, including unusually heavy rains; 
  Failure to meet our revenue or profit goals or operating budget; 
  Decline in demand for our common stock; 
  Downward revisions in securities analysts’ estimates or changes in global financial markets, global economies, 

and general market conditions; 

Investor perception of our industry or our prospects; 

  Technological innovations by competitors or in competing technologies; 
 
  Lawsuits; 
  Economic impact from the spread of any disease; 
  Our ability to integrate and operate the companies and the businesses that we acquire; 
  Actions by government or central banks; and 
  General economic trends. 

Gold Resource Corporation 
22 

 
 
 
 
 
Stock  markets  in  general  have  experienced  extreme  price  and  volume  fluctuations,  and  the  market  prices  of 
individual securities have been highly volatile. These fluctuations are often unrelated to operating performance and may 
materially adversely affect the market price of our common stock. As a result, shareholders may be unable to sell their 
shares at a desired price. 

Past payments of dividends on our common stock are not a guaranty of future payments of dividends. 

In 2010, we began paying cash dividends to the holders of our common stock. However, our ability to pay dividends 
in  the  future  will  depend  on  a  number  of  factors,  including  free  cash  flow,  expected  operational  performance,  mine 
construction  requirements  and  strategies,  other  acquisition  and/or  construction  projects,  spot  metal  prices,  taxation, 
government-imposed royalties, and general market conditions. Further, a portion of our cash flow is expected to be retained 
to  finance  our  operations,  explorations,  and  development  of  mineral  properties.  In  February  2023,  we  announced  the 
suspension of our quarterly dividends. There is no assurance that the Board will elect to re-institute a dividend payment in 
the near-term or at all. 

Issuances of our stock in the future could dilute existing shareholders and materially adversely affect the market 

price of our common stock. 

We have the authority to issue up to 200,000,000 shares of common stock, 5,000,000 shares of preferred stock, and 
to issue options and warrants to purchase shares of our common stock, in some cases without shareholder approval. As of 
March 20, 2024, there were 88,757,610 shares of common stock outstanding. Future issuances of our securities could be 
at prices substantially below the price paid for our common stock by our current shareholders. We can issue significant 
blocks of our common stock without further shareholder approval. Because we have issued less common stock than many 
of our larger peers, the issuance of a significant amount of our common stock may have a disproportionately large impact 
on our share price compared to larger companies. 

General Risks 

Our operations may be disrupted, and our financial results may be materially adversely affected by any future 

pandemic. 

 Any pandemic may pose a risk to our business and operations. If a significant portion of our workforce becomes 
unable  to  work  or  travel  to  our  operations  due  to  illness  or  state  or  federal  government  restrictions  (including  travel 
restrictions  and  “shelter-in-place”  and  similar  orders  restricting  certain  activities  that  may  be  issued  or  extended  by 
authorities), we may be forced to reduce or suspend exploration activities and/or development projects, which may impact 
liquidity and financial results. These restrictions have significantly disrupted economic activity in both the world, national 
and local economies and have caused volatility in capital markets. 

To the extent any pandemic materially adversely affects our business and financial results, as discussed above, it 
may also have the effect of heightening many of the other risks described in this “Risk Factors” section, such as those 
relating  to  our  operation,  indebtedness,  and  financing.  We  are  unable  to  predict  the  ultimate  adverse  impact  of  any 
pandemic  on  our  business,  which  will  depend  on  numerous  evolving  factors  and  future  developments,  including  the 
pandemic’s ongoing effect on the demand for silver and gold, as well as the response of the overall economy and the 
financial  markets  after  the  pandemic  and  response  measures  come  to  an  end,  the  timing  of  which  remains  highly 
unpredictable. 

The Israel-Palestinian conflict in Gaza, the conflict in Ukraine, and the related price volatility and geopolitical 

instability could negatively impact our business. 

On October 7, 2023, the Palestinian Sunni Islamist group, Hamas, led surprise attacks against Israel from the Gaza 
Strip. In response to the attacks, Israel’s cabinet formally declared war on Hamas. Although we do not have operations in 
the region, the extent and duration of the military action and resulting market disruptions could be significant and could 

Gold Resource Corporation 
23 

 
 
 
 
potentially have a substantial negative impact on the global economy and/or our business. The magnitude of these risks 
cannot be predicted, including the extent to which these conflicts may heighten other risks disclosed herein. 

In late February 2022, Russia launched significant military action against Ukraine, and the war remains ongoing. 
The extent and duration of the military action, sanctions, and resulting market disruptions could be significant and could 
potentially have a substantial negative impact on the global economy and/or our business for an unknown period of time. 
The  ramifications  of  the  hostilities  and  sanctions  may  not  be  limited  to  Russia, Ukraine, and  Russian  or  Ukrainian 
companies, and may spill over to and negatively impact other regional and global economic markets (including in Europe 
and  in  the  United  States),  companies  in  other  countries  (particularly  those  that  have  done  business  with  Russia 
and Ukraine), and various sectors, industries, and markets for securities and commodities globally. Any such volatility and 
disruptions may also magnify the impact of other risks described in this “Risk Factors” section. 

We may not be able to operate successfully if we are unable to recruit, hire, retain, and develop key personnel 
and maintain a qualified and diverse workforce. In addition, we are dependent upon our employees being able to safely 
perform their jobs, but there is risk of physical injuries or illness. 

We depend upon the services of a number of key executives and management personnel. These individuals include 
our executive officers and other key employees. If any of these individuals were to die, become disabled, or leave our 
company, we would be forced to identify and retain individuals to replace them. We may be unable to hire a suitable 
replacement on favorable terms should that become necessary.  

Our success is also dependent on the contributions of our highly skilled and experienced workforce. Our ability to 
achieve our operating goals depend upon our ability to recruit, hire, retain, and develop qualified and diverse personnel to 
execute on our strategy. There continues to be competition over highly skilled personnel in our industry. If we lose key 
personnel or one or more members of our senior management team; or if we fail to develop adequate succession plans; or 
if  we  fail  to  hire,  retain,  and  develop  qualified  and  diverse  employees;  our  business,  financial  condition,  results  of 
operations, and cash flows could be harmed.  

We are dependent on information technology systems, which are subject to certain risks, including cybersecurity 

risks, data leakage risks, and risks associated with implementation and integration. 

We are dependent upon information technology systems in the conduct of our business. Any significant breakdown, 
invasion,  virus,  cyberattack,  security  breach,  destruction,  or  interruption  of  these  systems  by  employees,  others  with 
authorized  access  to  our  systems,  or  unauthorized  persons  could  negatively  impact  our  business.  To  the  extent  any 
invasion, cyberattack, or security breach results in disruption to our business; such as loss or disclosure of, or damage to 
our  data  or  confidential  information;  our  reputation,  business,  results  of  operations,  and  financial  condition  could  be 
materially  adversely  affected.  We  have  implemented  various  measures  to  manage  our  risks  related  to  information 
technology  systems  and  network  disruptions.  However,  given  the  unpredictability  of  the  timing,  nature,  and  scope  of 
information  technology  disruptions,  we  could  potentially  be  subject  to  production  downtimes,  operational  delays,  the 
compromising  of  confidential  or  otherwise  protected  information,  destruction  or  corruption  of  data,  security  breaches, 
other manipulation or improper use of our systems, and networks or financial losses from remedial actions, any of which 
could have a material adverse effect on our cash flows, competitive position, financial condition, or results of operations. 
Our systems and insurance coverage for protecting against cyber security risks may not be sufficient. Although to date we 
have not experienced any material losses relating to cyberattacks, we may suffer such losses in the future. We may be 
required to expend significant additional resources to continue to modify or enhance our protective measures. We also 
may be subject to significant litigation, regulatory investigation, and remediation costs associated with any information 
security vulnerabilities, cyberattacks, or security breaches. 

We may also be materially adversely affected by system or network disruptions if new or upgraded information 
technology systems are defective, not installed properly, or not properly integrated into our operations. If we are unable to 
successfully implement system upgrades or modifications, we may have to rely on manual reporting processes and controls 
over  financial  reporting  that  have  not  been  planned,  designed,  or  tested.  Various  measures  have  been  implemented  to 

Gold Resource Corporation 
24 

 
 
 
 
manage our risks related to the system upgrades and modifications, but system upgrades and modification failures could 
have a material adverse effect on our business, financial condition, and results of operations and could, if not successfully 
implemented, adversely impact the effectiveness of our internal controls over financial reporting. 

Our business is subject to the U.S. Foreign Corrupt Practices Act and similar worldwide anti-bribery laws, a 
breach  or  violation  of  which  could  lead  to  civil  and  criminal  fines  and  penalties,  loss  of  licenses  or  permits,  and 
reputational harm. 

We  operate  in  certain  jurisdictions  that  have  experienced  some  degree  of  governmental  and  private  sector 
corruption, and in certain circumstances, strict compliance with anti-bribery laws may conflict with certain local customs 
and  practices.  The  U.S.  Foreign  Corrupt  Practices  Act  and  anti-bribery  laws  in  other  jurisdictions  generally  prohibit 
companies and their intermediaries from making improper payments for the purpose of obtaining or retaining business or 
other commercial advantages. Our Code of Ethics and other corporate governance mandate compliance with these anti-
bribery laws, which often carry substantial penalties. However, there can be no assurance that our internal control policies 
and  procedures  will  always  protect  us  from  recklessness,  fraudulent  behavior,  dishonesty,  or  other  inappropriate  acts 
committed  by our  affiliates, employees,  contractors,  or  agents. As  such,  our  corporate  policies  and processes  may not 
prevent  all  potential  breaches  of  law  or  other  governance  practices.  Violations  of  these  laws,  or  allegations  of  such 
violations, could lead to civil and criminal fines and penalties, litigation, loss of operating licenses or permits, and may 
damage  our  reputation,  which  could  have  a  material  adverse  effect  on  our  business,  financial  position,  and  results  of 
operations, or cause the market value of our common stock to decline.

CYBERSECURITY 

Risk Management and Strategy 

We  have  established  policies  and  processes  for  assessing,  identifying,  and  managing  material  risk  from 
cybersecurity threats and have integrated these processes into our overall risk management systems and processes. We 
routinely assess material risks from cybersecurity threats, including any potential unauthorized occurrence on or conducted 
through our information systems that may result in adverse effects on the confidentiality, integrity, or availability of our 
information systems or any information residing therein. 

We conduct periodic risk assessments to identify cybersecurity threats, as well as assessments in the event of a 
material change in our business practices that may affect information systems that are vulnerable to such cybersecurity 
threats. These risk assessments include identification of reasonably foreseeable internal and external risks, the likelihood 
and potential damage that could result from such risks, and the sufficiency of existing policies, procedures, systems, and 
safeguards in place to manage such risks. 

Governance 

One of the key functions of our Board of Directors is informed oversight of our risk management process, including 
risks  from  cybersecurity  threats.  Our  Board  is  responsible  for  monitoring  and  assessing  strategic  risk  exposure,  and 
management  is  responsible  for  the  day-to-day  management  of  any  material  risks  that  may  arise.  The  Board  receives 
periodic updates from management regarding cybersecurity matters and is notified between such updates regarding any 
significant  new  cybersecurity  threats  or  incidents.  We  do  not  believe  that  there  are  currently  any  known  risks  from 
cybersecurity threats that are reasonably likely to materially affect us or our business strategy, results of operations, or 
financial condition. 

 Management  is  responsible  for  the  operational  oversight  of  company-wide  cybersecurity  strategy,  policy,  and 
standards across relevant departments to assess and help prepare us to address cybersecurity risks. As part of our overall 

Gold Resource Corporation 
25 

 
 
 
 
 
 
risk management system, we monitor and test our safeguards and train our employees on these safeguards. Personnel at 
all levels and departments are made aware of our cybersecurity policies through trainings. 

Cybersecurity Threats 

As of December 31, 2023, we have not identified an indication of a cybersecurity incident that would have a material 
impact on our business and consolidated financial statements. For further discussion of cybersecurity risks, please refer to 
Item 1A. Risk Factors.

PROPERTIES 

Glossary  

The following terms used in this report shall have the following meanings:  

Andesite: 

Concentrate: 

Doré: 

Drift: 

Epithermal: 

Exploration: 

Grade: 

Hectare: 

An extrusive igneous, volcanic rock, of intermediate composition, with aphanitic to porphyritic
texture characteristic of subduction zones, such as the western margin of South America. 

A product from a mineral processing facility, such as gravity separation or flotation, in which
the  valuable  constituents  have  been  upgraded  and  unwanted  gangue  materials  rejected  as
waste. 

Composite gold and silver bullion, usually consisting of approximately 90% precious metals
that will be further refined to separate pure metals. 

A horizontal tunnel generally driven within or alongside an ore body and aligned parallel to
the long dimension of the ore. 

Used to describe gold deposits found on or just below the surface close to vents or volcanoes,
formed at low temperature and pressure. 

Prospecting,  sampling,  mapping,  diamond-drilling,  and  other  work  involved  in  locating  the
presence of economic deposits and establishing their nature, shape, and grade. 

The  concentration  of  an  element  of  interest  expressed  as  relative  mass  units  (percentage,
ounces per ton, grams per tonne (“g/t”), etc.). 

A  metric  unit  of  measurement,  for  surface  area.  One  hectare  equals  1/200th  of  a  square 
kilometer, 10,000 square meters, or 2.47 acres. A hectare is approximately the size of a soccer
field. 

Long-hole Stoping: 

Mining method which uses holes drilled by a production drill to a predetermined pattern by a
mining engineer. Long-hole stoping is a highly selective and productive method of mining and
can cater for varying ore thicknesses and dips (0 - 90 degree). Blasted rock is designed to fall 
into  a  supported  drawpoint  or  be  removed  with  remote  control LHD  (load,  haul,  dump 
machine).  

Net Smelter Return 
(“NSR”): 

The net revenue that the owner of a mining property receives from the sale of the mine's metal
products,  less transportation and  refining  costs.  As  a  royalty,  it  refers  to  the  fraction of  net
smelter return that a mine operator is obligated to pay the owner of the royalty agreement.  

Mineral Deposit: 

Rocks that contain economic amounts of minerals in them and that are expected to be profitably
mined.

Tonne: 

A metric ton. One tonne equals 1000 kg. It is equal to approximately 2,204.62 pounds. 

Volcanogenic: 

Of volcanic origin. 

Volcanic domes: 

These are mounds that form when viscous lava is erupted slowly and piles up over the vent,
rather than moving away as lava flow. The sides of most domes are very steep and typically 
are mantled with unstable rock debris formed during or shortly after dome emplacement. Most
domes are composed of silica-rich lava, which may contain enough pressurized gas to cause
explosions during dome extrusion. 

Overview 

We  classify  our  mineral  properties  into  three  categories:  “Production  Stage  Properties,”  “Development  Stage 
Properties,” and “Exploration Stage Properties.” Production Properties are properties for which we operate a producing 
mine. 

At our Don David Gold Mine, we currently have 100% interest in six properties, including two Production Stage 
Properties  and  four  Exploration  Stage  Properties,  located  in  Oaxaca,  Mexico,  along  the  San  Jose  structural  corridor. 
Because of their proximity and relatively integrated operations, we collectively refer to the six properties as the Don David 
Gold Mine. The two Production Stage Properties are the only two of the six properties that make up the Don David Gold 
Mine that we consider to be independently material at this time. Please see Item 2. Properties – Don David Gold Mine for 
further discussion of the properties. 

The Company also has 100% interest in the Back Forty Project, an advanced Exploration Stage Property, located 
in Menominee County, Michigan, USA. We do not consider the Back Forty Project to be independently material to the 
Company at this time. Please see Item 2. Properties – Back Forty Project for further discussion of the property. 

Mineral Resources 

Under S-K 1300, a Mineral Resource is defined as “a concentration or occurrence of material of economic interest 
in or on the Earth’s crust in such form, grade or quality, and quantity that there are reasonable prospects for economic 
extraction.” A Mineral Resource is a “reasonable estimate of mineralization, taking into account relevant factors such as 
cut-off  grade,  likely  mining  dimensions,  location  or  continuity,  that,  with  the  assumed  and  justifiable  technical  and 
economic conditions, is likely to, in whole or in part, become economically extractable. It is not merely an inventory of 
all mineralization drilled or sampled.”

1.  Mineral Resources estimated at December 31, 2022 are based on $1,650/oz for Gold, $20.00/oz for Silver, $3.40/pound Copper, $0.90/pound 
Lead and $1.35/pound Zinc. As a result of market volatility in 2022, these prices are based on conservative estimates which closely approximate 
the 12-month low for Gold ($1,620/oz), Silver ($18/oz), Copper ($3.35/pound), Lead ($0.80/pound), and Zinc ($1.25/pound). 
The definitions for Mineral Resources in S-K 1300 were followed which are consistent with CIM (2014) definitions and are exclusive of Mineral

During  2023,  we  performed  a  comprehensive  review  of  our  geological  database  and  interpretation  of  the 
mineralization, the block models derived from them, and ultimately the mine plan to ensure more reliable and accurate 
mine  planning  and  forecasting.  In  addition,  metallurgy,  mining  methods,  ground  control,  and  other  parameters  were

reviewed. As a result of this review, Measured and Indicated Mineral Resources decreased from approximately 1.6 million 
tonnes at December 31, 2022 to approximately 0.7 million tonnes at December 31, 2023. The contributing factors to this 
decrease was the reclassification of Measured and Indicated Mineral Resource to Proven and Probable Reserves resulting 
in  a  decrease  of  0.7  million  tonnes,  the  application  of  economic  constraining  parameters  (engineering)  resulting  in  a 
decrease of 1.4 million tonnes, and change in the NSR cutoff grade from $80/tonne to $100/tonne resulting in a decrease 
of 0.6 million tonnes. These reductions were partially offset by the addition of 1.8 million tonnes related to the 2023 infill 
and step-out drilling program. The total Inferred Mineral Resources decreased from approximately 2.1 million tonnes at 
December 31, 2022 to approximately 1.6 million tonnes at December 31, 2023. The decrease in Inferred Mineral Resources 
was mainly due to infill drilling and the reclassification of Inferred Mineral Resources to Measured and Indicated Mineral 
Resources along with optimized mine planning. 

More information regarding the assumptions, methodologies, and procedures utilized in the estimation of Mineral 
Resources at DDGM can be found in the updated Don David Gold Mine Technical Report Summary filed as Exhibit 96.2

Resources at Back Forty can be found in the Back Forty Technical Report Summary incorporated by reference as Exhibit 
96.1 to this Form 10-K. 

Mineral Reserves 

Under S-K 1300, a Mineral Reserve is defined as “an estimate of tonnage and grade or quality of indicated and 
measured  Mineral  Resources  that,  in  the  opinion  of  the  qualified  person,  can  be  the  basis  of  an  economically  viable 
project.”

Notes on Mineral Reserves: 

1.  Mineral Reserves estimated at December 31, 2022 are based on $1,650/oz for Gold, $20.00/oz for Silver, $3.40/pound Copper, $0.90/pound 
Lead  and  $1.35/pound  Zinc.  As  a  result  of  market  volatility  in  2022,  these  prices  are  based  on  conservative  estimates  which  closely 
approximate the 12-month low for Gold ($1,620/oz), Silver ($18/oz), Copper ($3.35/pound), Lead ($0.80/pound), and Zinc ($1.25/pound). 
The Arista Mine cut-off grades for Mineral Reserves are $80/tonne NSR. 

2. 
3.  No appreciable amounts of base metals are present in the Alta Gracia veins identified to-date. A breakeven cut-off grade of 2.35 g/t AuEq 

was used for Mineral Reserves using gold and silver only to calculate gold equivalencies. 

4.  Rounding of tonnes, average grades, and contained ounces may result in apparent discrepancies with total rounded tonnes, average grades, 

and total contained ounces.

Proven  and  Probable  Mineral  Reserves  decreased from  1.4 million  tonnes  at December 31,  2022  to 1.1 million 
tonnes  at  December  31,  2023.  The  largest  contributing  factors  for  this  decrease  were  the  depletion  of  reserves  by  0.5 
million tonnes related to 2023 mining activities, the reduction of 0.6 million tonnes due to the increase of the NSR cutoff 
grade from $80/tonne to $120/tonne. The deductions were partially offset by the reclassification of 0.7 million tonnes from 
Measured and Indicated Mineral Resources to Proven and Probable Mineral Reserves as a result of detailed engineering 
for the Arista Mine. 

More information regarding the assumptions, methodologies, and procedures utilized in the estimation of Mineral 

Reserves can be found in the DDGM Technical Report Summary filed as Exhibit 96.2 to this Form 10-K. 

Don David Gold Mine 

All of the properties that make up our Don David Gold Mine are located in Oaxaca, Mexico, in what is known as

Arista & Alta Gracia Mines 

History: The Arista and Alta Gracia mines are in the regional Tlacolula mining district within Oaxaca State, in 
southern  Mexico.  According  to  the  Mexican  Geological  Survey,  the  Servicio  Geologico  Mexicano  (“SGM”)  mining 
activity was initiated in the early 1880s in the Tlacolula mining district, producing some 300,000 ounces of gold and silver 
from  an  ore  shoot  in  the  La  Leona  mine.  However,  no  separate  amounts  of  production  were  reported  for  each  metal. 
According to the SGM, in 1892 two smelters were built and operated (Magdalena Teitipac and O'Kelly) near the village 
of Tlacolula for processing ores from the Alta Gracia La Soledad, San Ignacio y Anexas, La Leona, La Victoria, and San 
Rafael silver mines. Subsequently, in 1911, Mr. Sken Sanders investigated the Totolapam mining region with a particular 
interest in the Margaritas mine. Most of these historical mines are within DDGM's mining concessions. 

While the DDGM Arista Mine and Alta Gracia Mine are in the smaller mining subdistricts of San Jose de Gracia 
and Alta Gracia, respectively, only small-scale artisanal mining was historically conducted in these areas’ subdistricts. No 
reliable production records exist for the historic production performed in the Arista and Alta Gracia Project areas. 

Arista Mine 

Background: The Arista Mine currently holds 18 mining concessions aggregating 24,372 hectares. 

In 2002, the initial three concessions were leased from a third-party. Two of the concessions are part of the Arista 
Mine, and the third concession comprises the Margaritas property. The lease agreement is subject to a 4% net smelter 
return royalty where production is sold in the form of gold/silver doré and 5% for production sold in concentrate form. 
Subject to meeting minimum exploration requirements, there is no expiration term for the lease. We may terminate it at 
any time upon written notice to the lessor, and the lessor may terminate it if we fail to fulfill any of our obligations, which 
primarily consist of paying the appropriate royalty to the lessor. 

In August 2003, initial drilling and exploration program commenced at the Arista mine. Through the end of 2023, 
we  have  drilled  a  total  of  1,794  core  holes  (both  surface  and  underground)  totaling  482,271  meters  and  166  reverse 
circulation holes equaling 14,367 meters, for a total of 1,960 holes totaling 496,638 meters.

 In 2010, additional concessions were acquired from a third-party at no additional cost, which are subject to a 2% 
royalty. We filed for and received additional concessions from the Mexican government which are also not part of the 
concessions leased or acquired from the third-party. Two concessions are considered within the Arista mine. 

Location and Access: The Arista mine is located in the Sierra Madre del Sur Mountains of southern Mexico in the 
central part of the State of Oaxaca. The property is located along a major paved highway approximately 120 kilometers 
southeast of Oaxaca City, the state’s capital city. The property is approximately four kilometers northwest from the village 
of San Jose de Gracia. We have constructed gravel and paved roads from the village to the mine and processing facility, 
which provide adequate access to the property.  

The climate of the Arista mine area is dry and warm to very warm with most rainfall occurring in June through 
September, and annual precipitation averaging 423.7 mm. The average yearly temperature is 26.6 degrees centigrade. The 
area is very rocky with arid vegetation. Subsistence farming occurs, and the main agricultural crop is agave cactus that is 
cultivated for the production of mescal.

Geology  and  Mineralization:  The  Arista  mine  is  located  in  the  San  Jose  de  Gracia  Mining  District  in  Oaxaca. 
Multiple volcanic domes of various scales, and likely non-vented intrusive domes, dominate the district geology. These 
volcanogenic features are imposed on a pre-volcanic basement of sedimentary rocks. Gold and silver mineralization in 
this district is related to the manifestations of this classic volcanogenic system and is considered epithermal in character.  

Historically, we have produced ore from two locations on the Arista mine, the open pit mine and the underground 
mine. The open pit mineralization is considered low sulfidation epithermal-type with consisting primarily of gold with 
some silver and no base metals. In 2021, mining activities were completed in the open pit, and it is now being backfilled 
and  reclaimed  by  filtered  dry  stack  tailings  deposition.  The  Arista  underground  mine  mineralization  is  considered 
intermediate epithermal-type consisting of gold, silver, copper, lead, and zinc. The host rock in the Arista vein system is 
primarily andesite. 

Facilities: The processing facility and other infrastructure at the Arista mine was constructed for approximately $35 
million in 2009, and the processing facility was expanded in 2012 and 2013 for additional $23 million. The flotation mill 
expansion, completed at the end of 2013, increased the number of flotation cells, added a second ball mill to allow for 
additional  processing  capacity,  and  added  a  Knelson  gravity  concentrator.  In  2014,  a  doré  processing  facility  was 
completed. In 2019, an increase in pumping capacity to the cyclones in the plant resulted in plant capacity increasing to 
nominal  2,000  tonnes  per  day.  The  DDGM  processing  facility  is  flexible  in  its  ability  to  process  several  types  of 
mineralization.  It  has  a  differential  flotation  section  capable  of  processing  polymetallic  ore  and  producing  up  to  three 
separate concentrate products. The facility also has an agitated leach circuit capable of producing gold and silver doré.  

We obtained water rights from the Mexican government for an amount of water that we believe is sufficient to meet 
our operating requirements and pump it approximately five kilometers to the site from a permitted well located near the 
Totolapam River. 

Gold Resource Corporation 
34 

 
 
 
 
 
Additional improvements at the site include electrical power lines connecting to the Mexican national power grid, 
installation of backup diesel generation power plants and switch gear, paving a three-kilometer section of the road from 
the mine to the processing facility, construction of a surface maintenance garage and fuel station, construction of haul 
roads from the mine site to the processing facility, office space at the processing facility, an assay lab, an exploration 
office, tailings impoundment facilities and lift, a paste fill plant, mine camp facilities, the filtration plant, the dry stack 
facility, and other infrastructure. 

Exploration Activities: In 2023, an extensive underground drilling campaign at the Arista mine was successfully 
executed, completing 168 diamond drill holes totaling 36,350 meters. This program included a total of 150 underground 
infill drill holes, totaling 26,057 meters, with a specific emphasis on upgrading Mineral Resources to Mineral Reserves 
and delineating the multiple sub-parallel veins within the Switchback system. Drilling here identified a number of high-
grade zones up- and down-dip of existing workings, both within and peripheral to existing Mineral Resources. In late 
2023, infill drilling also got underway in the Three Sisters vein system to begin converting Inferred Mineral Resources, 
identified earlier in the year during expansion drilling, to Mineral Reserves. 

Underground expansion drilling activities were also completed at the Arista mine during 2023, encompassing a 
total of 18 drill holes totaling 10,293 meters. Expansion drilling focused on the Three Sisters and North Arista vein systems, 
as well as on the newly discovered Gloria vein system identified through expansion drilling during the first quarter of 
2023. The objective of expansion drilling is to delineate additional Mineral Resources. Both the Arista and Switchback 
vein systems extend for over 1.5 kilometers in strike length, and both systems remain open along strike and in the vertical 
extent. The Gloria vein system, a new discovery, is located between and north of the Arista and Switchback vein systems, 
near existing mine infrastructure. Expansion drilling of the Gloria vein system in 2023 has defined a minimum of three 
new veins with true widths locally in excess of six meters. The Three Sisters vein system lies at the northern limit of the 
Arista mine underground workings and also between the Switchback and Arista vein systems. The Tree Sisters drilling 
during 2023 focused on the Sandy veins, which are open to the northwest and up- and down-dip. Both the Gloria and Three 
Sisters vein systems will be a primary focus of continued infill and expansion drilling in 2024. 

Surface  exploration  activity  during  2023  focused  on  the  Alta  Gracia  property with  the  interpretation  of  surface 
mapping and soil geochemistry results generated in late 2022. This work has identified several targets for future follow-
up  exploration  activity.  Our  exploration  efforts  on  the  Arista,  Alta  Gracia,  and  other  properties  demonstrate  our 
commitment to long-term investment and the potential to extend our operations into the future in Oaxaca, Mexico.  

Please see Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations for 

additional information concerning our mining operations at the Alta Gracia project.  

Alta Gracia Mine 

Background: In 2008, we were granted claims adjacent to the Margaritas property in the Alta Gracia Mining District 
by filing three mining concessions known as the David Fracción I, the David Fracción II, and La Herradura, totaling 5,175 
hectares. 

As of December 31, 2016, proven and probable reserves had been established for the Mirador Underground Mine 
on our Alta Gracia property. In July 2017, mine development reached the economic ore zone of the Mirador vein, and 
mining began.  

Location and Access: The Alta Gracia project is approximately 20 kilometers northeast of the village of San Pedro 
Totalapam, in the Municipality of San Pedro Totolapam. Access to the project is by a gravel road that departs the paved 
highway approximately 13 kilometers east of the village of San Pedro Totalapam. The haulage distance by road from Alta 
Gracia to the DDGM processing facility is approximately 32 kilometers. 

Gold Resource Corporation 
35 

 
 
 
 
Geology  and  Mineralization:  The  sedimentary  and  volcanic  units  mapped  at  Alta  Gracia  are  similar  to  those 
observed at the Arista mine. The district is dominated by tertiary-age rhyolite flows and tuffs, which are underlain by 
andesite flows and tuffs. Granodiorite and felsic intrusives are observed to crop out to the north and east of the Mirador 
mine. Known vein occurrences at Alta Gracia are mainly hosted in andesite and rhyolite. The veins at Alta Gracia are 
considered low sulfidation epithermal mineralization with economic values only for gold and silver. 

Facilities: During 2016, we received our operating permit for the Mirador Mine. In 2017, two mine portals were 
developed  to  provide  access  to  the  Mirador  vein.  Mine  site  offices  and  a  mobile  equipment  maintenance  shop  were 
established. Additionally, a diesel power generation plant, a compressed air system, and a mine water pumping station 
were developed and put into service. In 2018, old workings were improved to create a second access to the vein system 
called  Independencia.  The  portal  for  this  access  is  located  approximately  500 meters  southwest of  the  Mirador portal. 
Development was established to access the mineralization, delineated by drill campaigns completed during 2018 and 2019 
on the Mirador’s Independencia vein. 

Ore from the Mirador Mine, primarily silver ore, was transported by contracted haul trucks to and processed at our 

agitated leach plant at the DDGM processing facility, with the final product being doré. 

Exploration Activities: In 2023, surface exploration activity was centered around the Alta Gracia property area. In 
late  2022  and  continuing  into  early  2023,  a  surface  mapping  and  soil  geochemical  program  was  carried  out  in  the 
Aguacatillo prospect over an area to the south-west, west, and north-west of the Independencia and Mirador mines. The 
objective of this work was to test for possible westerly extensions of mineralization extending from the Independencia and 
Mirador mines. The program was successful in identifying several anomalous zones, which will be used to target follow-
up  detailed  mapping  to  identify  additional  potential  targets  for  future  surface  drilling.  In  addition,  analysis  and 
interpretation  was  completed  in  2023  of  the  geochemical  results  generated  from  a  regional  soil  sampling  program 
completed in late 2022 in the La Fundicion prospect area located immediately south-southeast of the Independencia and 

Gold Resource Corporation 
36 

 
 
 
 
 
Mirador mines. This interpretation was successful in identifying three distinct clusters of anomalous gold- and silver-in-
soil anomalies, which will be followed up with detailed geologic mapping and rock chip sampling. 

Exploration Properties 

Margaritas Property  

The Margaritas property is made up of the La Tehuana concession, which is approximately 925 hectares, located 

within the 55-kilometer San Jose structural corridor and adjacent to the Arista mine. 

In 2023, we continued to review results from previous surface drilling, surveying, detailed geological mapping, and 
rock chip channel sampling for the Margaritas property. We completed the work required to maintain the claims during 
2023, with work focused on analysis of spectral and geophysical information to identify new targets of interest. We expect 
to target a similar amount of work in 2024, along with identifying opportunities to strengthen our relationship in the local 
communities. 

Chamizo Property 

In  June  2011,  we  acquired  an  exploration  concession  from  the  Mexican  government  of  approximately  17,898 
hectares referred to as Chamizo. In March 2013, we acquired a property known as Cerro Colorado from Almaden Minerals, 
Ltd. (“Almaden”) consisting of approximately 1,860 hectares. The Cerro Colorado property is surrounded by our Chamizo 
concession,  and  we  include  it  as  part  of  the  Chamizo  property.  The  Chamizo  Property  is  adjacent  to  the  Alta  Gracia 
property. Any future production from the Cerro Colorado concession is subject to a 2% net smelter return royalty in favor 
of Almaden. 

During 2022, surface mapping and geochemical sampling were begun in the Jabali prospect area. Results of this 
work were reviewed and analyzed in 2023 in order to plan additional detailed follow up geologic mapping and target 
evaluation. Different targets within the Chamizo property will continue to be evaluated in 2024, while also looking to 
identify opportunities to strengthen our relationship in the local communities to facilitate future work. 

Fuego Property 

In March 2013, we acquired the Fuego property from Almaden subject to a 2% net smelter return royalty. The 
Fuego property consists of approximately 2,554 hectares and is located south of our Alta Gracia and Chamizo properties. 
In 2013, Fuego was included in the property-wide airborne geophysical survey. Geologic mapping and surface sampling 
have been conducted on the Fuego property, which allows us to meet the acceptable amount of work required to maintain 
the claims. We do not anticipate any significant exploration activities at Fuego in 2024. However, we do plan to conduct 
the work required to maintain the claims. 

Rey Property 

The Rey property consists of concessions on the far north-west end of our 55-kilometer structural corridor in the 
State  of  Oaxaca  known  as El  Rey,  El  Virrey,  La  Reyna, and El  Marquez,  totaling  2,335  hectares.  We  acquired  the El 
Virrey concession  from  a  third-party,  and  it  is  subject  to  a  2%  net  smelter  return  royalty.  We  obtained  the  remaining 
concessions by staking claims and filing for concessions with the Mexican government. 

The Rey  property  is  located  approximately  64  kilometers  by  road  from  the  Arista  mine.  There  is  no  plant  or 
equipment on the Rey property. If exploration is successful, any mining would probably require an underground mine 
where ore could be trucked to the DDGM processing facility for processing. To date, we have drilled 48 core holes for a 
total of 5,273 meters at the Rey property. Early in 2012, we completed a small amount of work to finish refurbishing and 
extending an existing shaft on the property to permit underground exploratory drilling. We ceased work at the Rey property 
during  2012,  following  a  request  to  obtain  additional  approvals  from  local  community  agencies.  In  2024,  we  plan  to 
continue working with the local agencies to understand and address any concerns the community may have, but we have 

Gold Resource Corporation 
37 

 
 
 
 
no assurance that we will be able to resume our exploration activities in the near term. Once community support is obtained, 
we plan to conduct follow-up drilling and exploration based on the drilling done in 2007 and 2008. While negotiations 
continue, we will complete enough work to maintain the claims in good standing. 

Mining Concessions and Regulations in Mexico 

Mineral rights in Mexico belong to the Mexican federal government and are administered pursuant to Article 27 of 
the Mexican Constitution. All of our mining concessions are exploitation concessions, which may be granted or transferred 
to Mexican citizens and corporations. Our leases or concessions are held by our Mexican subsidiary DDGM. Exploitation 
concessions have a term of 50 years and can be renewed for another 50 years. Concessions grant us the right to explore 
and exploit all minerals found in the ground. Maintenance of concessions requires the semi-annual payment of mining 
duties (due in January and July) and the performance of assessment work, on a calendar year basis, with assessment work 
reports required to be filed in the month of May for the preceding calendar year. The amount of mining duties and annual 
assessments  are  set  by  regulation,  may  increase  over  the  life  of  the  concession,  and  include  periodic  adjustments  for 
inflation. Failure to pay the mining duties can lead to the cancelation of the relevant concession. 

Mexican mining law does not require payment of finder’s fees to the government, except for a discovery premium 
in connection with national Mineral Reserves, concessions and claims, or allotments contracted directly from the Mexican 
Geological Survey. None of the claims held by DDGM are under such a discovery premium regime.  

Ejido Lands and Surface Right Acquisitions in Mexico  

Surface  lands  within  DDGM  are  Ejido  lands  (agrarian  cooperative  lands  granted  by  the  federal  government  to 
groups of Campesinos pursuant to Article 27 of the Mexican Constitution of 1917). Prior to January 1, 1994, Ejidos could 
not transfer Ejido lands into private ownership. Amendments to Article 27 of the Mexican Constitution in 1994 now allow 
individual  property  ownership  within  Ejidos  and  allow  Ejidos  to  enter  into  commercial  ventures  with  individuals  or 
entities,  including  foreign  corporations.  We  have  an  agreement  with  the  local  San  Pedro  Totolapam  Ejido,  allowing 
exploration and exploitation of mineralization at the Arista mine and some of our surrounding properties.  

Mexican law recognizes mining as a land use generally superior to agriculture. However, the law also recognizes 
the rights of the Ejidos to compensation in the event mining activity interrupts or discontinues their use of the agricultural 
lands. Compensation is typically made in the form of a cash payment to the holder of the agricultural rights. The amount 
of such compensation is generally related to the perceived value of the agricultural rights as negotiated in the first instance 
between the Ejidos and the owner of the mineral rights. If the parties are unable to reach an agreement on the amount of 
the compensation, the decision can be referred to the government.  

We have established surface rights agreements with the San Pedro Totolapam Ejido and the individuals impacted 
by  our  proposed  operations  which  allow  disturbance  of  the  surface  where  necessary  for  our  exploration  activities  and 
mining operations. 

Office Facilities  

We  constructed  an  administrative  office  building  adjacent  to  the  DDGM  processing  facility  and  a  mine  office 
adjacent to the Arista Mine portal. We also lease approximately 3,000 square feet of office space in Oaxaca City, Oaxaca. 
The lease commenced in 2012 and was renewed in December 2021 through the end of 2024.

Back Forty Project 

The Back Forty Project is an advanced Exploration Stage Property located in Menominee County, Michigan, USA 
in the mineral rich Penokean Volcanic Belt. Our property is made up of approximately 1,304 hectares (3,222 acres) of 
private and public (State of Michigan) mineral lands. The project is centered at latitude 46 degrees 27 North and longitude 
87 degrees 51 West. Because of the exploratory nature of the property, we do not currently consider the Back Forty Project 
to be independently material to the Company. 

Background: On December 10, 2021, the Company successfully completed the acquisition of all the issued and 
outstanding common shares of Aquila Resources Inc. Aquila’s principal asset is its 100% interest in the Back Forty Project 
located in Menominee County, Michigan, USA. The Back Forty Project has a polymetallic (gold, silver, copper, lead, and 
zinc)  Volcanogenic  Massive  Sulfide  deposit.  The  Back  Forty  Project  controls  surface  and  mineral  rights  through 
ownership, leases with the State of Michigan, and royalties with private parties. 

Optimization work related to the metallurgy and the economic model for the Back Forty Project was completed, 
and  the  Company  released  the  Back  Forty  Project  Technical  Report  Summary,  which  is  incorporated  by  reference  as 
Exhibit 96.1 to this Form 10-K. Results of the work indicate a more robust economic project with no planned impacts to 
wetlands that is more protective of the environment, which should facilitate a successful mine permitting process. The 
Board continues to evaluate options that could lead to the development of the Project. Please see Item 2. Properties for 
additional information. 

Permitting:  The  State  of  Michigan  governs  and  regulates  the  permitting  process  as  it  relates  to  the  Back  Forty 

Project. 

Community: Tribal engagement has been very important to the Project, especially considering the cultural resources 
near the site. Outreach to local Tribes, including the Menominee Indian Tribe of Wisconsin, began as early as June of

2010. Aquila conducted extensive archeological studies throughout the affected and unaffected areas. As agreed with the 
authorities, Aquila identified areas for permanent protection and established appropriate buffers.  

Office Facilities: In Michigan, we own and operate an administrative office building in Stephenson, MI and another 

field office close to the location of the potential future mine facilities.

LEGAL PROCEEDINGS  

In February 2020, a local Ejido community (who claim to be an indigenous community) filed an injunction against 
the  Mexican  federal  government  through  which  they  demanded  the  cancelation  of  several  concession  titles,  including 
concessions  currently  granted  to  DDGM.  The  federal  government  ordered  a  suspension  to  prevent  work  related  to 
excavating, drilling, opening tunnels, and exploiting the Mineral Resources on the surface and subsoil of the concessions 
named in the injunction in the lands of the indigenous community. Presently, DDGM does not perform such works in the 
named  concessions  in  lands  of  the  indigenous  community.  The  lawsuit  filed  in  February  2020  at  the  First  District 
Courthouse in the state of Oaxaca remains under review by the courts.

MANAGEMENT’S  DISCUSSION  AND  ANALYSIS  OF  FINANCIAL  CONDITION  AND 
RESULTS OF OPERATIONS  

Except  for  the  historical  information,  the  following  discussion  contains  forward-looking  statements  that  are 
subject to risks and uncertainties. We caution you not to put undue reliance on any forward-looking statements, which 
speak only as of the date of this report. See “Forward-Looking Statements” above. Our actual future results or actions 
may differ materially from these forward-looking statements for many reasons, including but not limited to the risks 
described in “Item 1A. Risk Factors” and elsewhere in this annual report and other reports filed by us with the SEC. 
This discussion and analysis of our financial condition and results of operations should be read in conjunction with 
the audited consolidated financial statements and related notes included in this report and with the understanding that 
our actual future results may be materially different from what we currently expect. 

Introduction 

We are a mining company that pursues gold and silver projects that are expected to achieve both low operating 
costs and high returns on capital. DDGM holds six properties and includes mineral production primarily from the Arista 
underground mine. We produce gold and silver doré and metal concentrates which contain precious metals of gold and 
silver and base metals of copper, lead, and zinc. 

The following discussion summarizes our results of operations for the two fiscal years ended December 31, 2023 
and 2022 and our financial condition as of December 31, 2023 and 2022, with a particular emphasis on the year ended 
December 31, 2023.  

The  discussion  also  presents  certain  non-GAAP  financial  measures  that  are  important  to  management  in  its 
evaluation of our operating results and which are used by management to compare our performance with what we perceive 
to be peer group mining companies and are relied on as part of management’s decision-making process. Management 
believes these measures may also be important to investors in evaluating our performance. For a detailed description of 
each of the non-GAAP financial measures, please see the discussion under Item 7. Management’s Discussion and Analysis 
of Financial Condition and Results of Operations below. 

In our financial statements, we report the sale of all precious and base metals as revenue, and we periodically review 
our revenue streams to ensure that this treatment remains appropriate. We consider precious metals to be the long-term 
primary driver of our economic decisions and believe that base metals are secondary products for non-GAAP financial 
measures. 

Gold  equivalent  is determined by  taking gold  ounces produced  and sold, plus  silver ounces  produced  and  sold, 

converted to gold equivalent ounces using the gold to silver average realized price ratio for the period.

(1)  During the first and second quarter of 2022 and during the first quarter of 2023, tonnes milled includes 1,043, 215, and 1,060 purchased tonnes, 
respectively, related to a collaborative initiative with a local community to ensure the proper environmental treatment and storage of the material. 

(2)  Based on actual days the mill operated during the period. 
(3)  The difference between what we report as "ounces/tonnes produced" and "payable ounces/tonnes sold" is attributable to the difference between the 
quantities of metals contained in the concentrates we produce versus the portion of those metals actually paid for according to the terms of our sales 
contracts. Differences can also arise from inventory changes incidental to shipping schedules, or variances in ore grades and recoveries, which 
impact the amount of metals contained in concentrates produced and sold.

Full-year 2023 compared to full-year 2022 

Key drivers in the production and financial results for the twelve months ended December 31, 2023, as compared 
to the same period in 2022, relate to the lower tonnes mined and changes in metal grades. These results align with the 2023 
mine plan and were considered in the 2023 guidance disclosed in the 2022 Annual Report. Financial results have also been 
impacted unfavorably by the strengthening Mexican peso and the lower zinc price realized in 2023. 

Grades & Recoveries 

During the twelve months ended December 31, 2023, we processed ore with an average gold grade of 1.73 g/t, as 
compared to 2.56 g/t for the same period in 2022. Full-year average gold grade was approximately 32% lower than the 
prior year, in line with our mine sequencing plan. The average silver grade for the year ending 2023 increased 2% to 85 
g/t. While silver grade and recovery were similar to prior year, recovery for gold declined 5% in 2023 and is in line as per 
mine plan. As shown in the DDGM Technical Report Summary filed as Exhibit 96.2 to this Form 10-K, gold and silver 
grades are expected to decline over time, in line with the life of mine average shown in the Mineral Reserve and Mineral 
Resource tables. As grades decline, recoveries are expected to decline as well; however, there are other factors that may 
influence this general assumption. 

Our base metal average grades for the twelve months ended December 31, 2023 were 0.36% for copper, 1.52% for 
lead, and 3.45% for zinc, compared to 0.39% for copper, 1.80% for lead, and 4.36% for zinc in 2022. Copper, Lead and 
zinc grades for the 12 months ending December 31, 2023 declined by 8%, 16% and 21%, respectively, in line with our 
mine sequencing plan. As shown in the DDGM Technical Report Summary filed as Exhibit 96.2 to this Form 10-K, future 
recoveries and grades are expected to be in line with the life of mine average shown in the Mineral Reserve and Mineral 
Resource tables. 

Production 

For the year ended December 31, 2023, the Oaxaca operations processed 459,171 tonnes of ore, at an average rate 
of 1,436 daily tonnes, a decrease of 7% in material processed and a decrease of 2% in tonnes milled per day from prior 
year. 20,328 gold ounces and 1,142,138 silver ounces were produced, reflecting a decrease of 40% and 6%, respectively, 
from  the  same  period  in  2022.  The  production  decrease  for  gold  is  directly  related  to  the  decrease  in  gold  grade  and 
recovery in 2023 as compared to the same periods in 2022. Production for copper, lead, and zinc decreased by 10%, 24%, 
and 25%, respectively, for the three months ending December 31, 2023, compared the same period in 2022. Production 
decreases are mostly related to the decrease in base metal grades in 2023 compared to the same periods in 2022, as well 
as a result of lower tonnes processed, as expected and in line with the 2023 mine plan. 

Metals produced and sold is less than the amount of metals produced because a portion of the metals present in the 
materials  shipped  is  withheld  by  the  purchaser  of  our  doré  and  concentrates  under  the  terms  of  the  Company’s  sales 
contracts,  as  explained  above.  The  percentage  payable  metal—the  amount  of  metal  sold  as  a  percent  of  the  metal 
produced—were higher for all metals for the twelve months ended December 31, 2023, compared to same period in 2022, 
due to the minerology of the material mined.

Full-year 2023 compared to full-year 2022 

Metal Sold 

During the twelve months ended December 31, 2023, gold sales of 18,534 ounces, silver sales of 1,036,229 ounces, 
copper sales of 1,231 tonnes, lead sales of 4,501 tonnes, and zinc sales of 10,954 tonnes decreased by 38%, 2%, 9%, 17%, 
and 23%, respectively, as compared to the same period in 2022. These decreases were expected due to mine sequencing. 

Average metal prices realized 

During the twelve months ended December 31, 2023, the average metal prices were $1,955 per ounce for gold, 
$23.68  per  ounce  for  silver,  $8,513  per  tonne  for  copper,  $2,158  per  tonne  for  lead,  and  $2,621  per  tonne  for  zinc. 
Compared to the same period in 2022, the average metal price for gold, silver, and lead increased by 9%, 10%, and 1%, 
respectively, while the average metal price for copper and zinc decreased by 3% and 26%, respectively.

Full-year 2023 compared to full-year 2022 

Sales, net 

DDGM net sales of $97.7 million for the year ended December 31, 2023 decreased by $41.0 million, or 30%, when 
compared to 2022. The decrease in 2023 sales is the result of lower tonnes processed and lower grades for gold and base 
metals. 

Treatment charges 

Treatment charges for the twelve months ended December 31, 2023, were $11.6 million, or $697 per tonne of base 
metal produced and sold, as compared to $12.1 million, or $578 per tonne of base metal produced and sold for the same 
period in 2022. This 21% cost increase in treatment charge per metal tonne sold due to a 32% increased contractual rate 
for copper treatment charges and for a 21% increase in zinc treatment charges which are based on spot and benchmark 
rates. These are slightly offset by a 30% decrease in contractual rate for lead treatment charges. 

Total cost of sales 

Total cost of sales of $103.0 million in 2023 decreased by $5.9 million, or 5%, compared to 2022. The primary 

driver is the $4.8 million, or 6% decrease in production costs from $80.9 million in 2022 to $76.1 million in 2023, and a 
$1.1 million, or 4% decrease in depreciation expense. The decrease in production costs is related to lower production in 
2023.

Mine gross (loss) profit 

For the year ended December 31, 2023, mine gross loss and mine gross loss percent totaled $5.3 million and 5% 
respectively, as compared to a mine gross profit and mine gross profit percent of $29.7 million and 21% for the same 
period in 2022. The decrease in mine gross profit and loss and mine gross profit and loss percent of $35.1 million and 
27%, respectively, when compared to the same period in 2022, primarily resulted from the $41.0 million decrease in net 
sales year-over-year. 

The relationship between sales and operating costs, and therefore mine gross profit or loss, is not perfectly correlated 
to the tonnes of ore processed. While both sales and operating costs are impacted by the tonnes of ore processed, other 
factors—the grade of ore processed, metal commodity prices, and operating cost unit prices—tend to have a greater impact 
on the relationship to mine gross profit. For example, in 2023, the volume of ore processed decreased 7% compared to 
2022, with net sales also decreasing by 30% and operating costs decreasing by 40%. The decrease in 2023 net sales when 
compared to 2022 is explained by the 32% decrease in gold grade and the base metal grade decreases for copper, lead, and 
zinc of 8%, 16%, and 21%, respectively. The decrease in operating costs is explained chiefly by the targeted decreases in 
exploration and general and administrative expenses. 

We expect grades to vary from period to period based on the annual mine plan. The gold grades are expected to 
trend downwards over time, toward the average grade of 1.29 g/t (exclusive of silver, copper, lead, and zinc contained 
grades), reflected in our Mineral Reserves estimate. However, as capital intensive mine development progresses and infill 
drilling occurs, opportunities to refine mining methods and eliminate dilution may have a favorable impact on future mined 
grades. 

One component of gross profit or loss is concentrate treatment charges, which are netted against concentrate sales. 
These treatment charge agreements are negotiated on an annual basis with the spot rate adjusted quarterly on zinc. The 
decrease in treatment charges in 2023 compared to 2022 was the result of lower metals production and therefor decreased 
revenue as compared to 2022 due to both reduced tonnes mined and processed, and lower grades realized on the tonnage. 

Net loss 

For the year ended December 31, 2023, we recorded a net loss from operations of $16.0 million, as compared to 

$6.3 million net loss during the same period in 2022. The change was attributable to the factors noted above.

General and administrative expenses: For the year ended December 31, 2023, general and administrative expenses 
totaled $6.6 million compared to $8.0 million for the same period of 2022. The $1.4 million decrease in the twelve months 
ended December 31, 2023, as compared to the same period in 2022, is due allocating more job duties directly related to 
production at DDGM from corporate employees in 2023. 

DDGM  Exploration  expenses:  For  the  years  ended  December  31,  2023  and  2022  DDGM  exploration  expenses

work was completed in October 2023. 

Stock-based compensation: For the year ended December 31, 2023, stock-based compensation expense totaled $0.7 
million as compared to $2.0 million for the year ended December 31, 2022. This decrease is due to personnel changes and 
lower share price in 2023. 

Other expense, net: For the year ended December 31, 2023, we recorded other expense of $3.4 million compared 
to $4.3 million during the year ended December 31, 2022. The $0.9 million decrease from 2022 was due to $0.7 million 
lower realized and unrealized currency gains and losses and lower other expense that includes $0.7 million lower expense 
related to the contingent consideration, offset by $0.6 million higher interest on the streaming liabilities and $0.9 million 
higher severance payments in 2023 due to planned reduction of work force. Please see Item 8. Financial Statements and 
Supplementary Data—Note 17. Other (Income) Expense, Net for additional information. 

Provision for income taxes. For the year ended December 31, 2023, income tax benefit increased to $5.7 million 
from an $8.6 million income tax expense for the same period in 2022. The 2023 income tax benefit is primarily driven by 
the  decrease  in  pre-tax  income  at  DDGM.  Please  see  Item  8.  Financial  Statements  and  Supplementary  Data—Note  4. 
Income Taxes for additional information.

Other Non-GAAP Financial Measures 

Certain Non-GAAP financial measures are discussed below. For a detailed description of each of these measures 
and a reconciliation to GAAP financial measures, please see the discussion under Item 7. Management’s Discussion and 
Analysis of Financial Condition and Results of Operations—Non-GAAP Measures below. 

Full-year 2023 compared to full-year 2022 

Total cash cost after co-product credits per AuEq oz sold: For the twelve months ended December 31, 2023, the 
total cash cost after co-product credits per AuEq oz sold was $1,250 compared to $458 for the same period in 2022. The 
increase is due to the lower amount of co-product credits we received during the twelve months ended December 31, 2023, 
the 27% decrease in total number of AuEq ounces sold, and the 4% decrease in treatment and refining charges as a result 
of an increase in the zinc treatment charge benchmark and spot price. Although production costs were lower for the twelve 
months ended December 31, 2023 compared to the same period last year, the strengthening peso and increased energy 
costs negatively impacted production costs and, therefore, the cost per tonne processed and the total cash cost after co-
product credits per AuEq oz sold. 

Total consolidated all-in sustaining cost after co-product credits per AuEq oz sold: For the twelve months ended 
December 31, 2023, the total consolidated all-in sustaining cost after co-product credits per AuEq oz sold was $1,864 
compared  to  $1,093  for  the  same  period  in  2022.  The  increase  is  directly  related  to  the  higher  cash  costs  per  ounce 
discussed above, partially offset by lower sustaining capital expenditures. 

Total all-in cost after co-product credits per AuEq oz sold: For the twelve months ended December 31, 2023, the 
total all-in cost after co-product credits per AuEq oz sold was $2,062 compared to $1,442 for the same period in 2022. 
The increase is due to the higher all-in sustaining costs discussed above, offset by lower Back Forty costs due to completion 
of the optimization work in October 2023. 

For a detailed description of each of  the non-GAAP financial measures and a reconciliation to GAAP financial 
measures, please see the discussion below under Item 7. Management’s Discussion and Analysis of Financial Condition

The  Company’s  investment  in  Mexico  totaled  $15.1  million  in  2023.  Our  investment  in  Mexico  is  focused  on 
favorably  impacting  our  environmental,  social,  and  governance  programs  while  creating  operational  efficiencies  and 
longevity. At the Back Forty Project, $1.6 million was spent to wrap up the optimization work and to release the Back 
Forty Project Technical Report Summary, which was filed as Exhibit 96.1 to the Form 8-K filed on October 26, 2023.

Underground and Exploration Development: Mine development during the quarter included ramps and accesses to 
different areas of the deposit, vertical shafts, and exploration development drifts. A total of 2,420 meters of underground 
development and exploration development, at a cost of $5.9 million, was completed during the year, including access to 
new exploration drill stations for both infill and expansion programs. 

Back Forty Feasibility and Permitting: Work on optimizing the Back Forty Project was completed during the third 
quarter of 2023. Mine planning, process plant design, site layout, and infrastructure were largely completed during 2022. 
As a result, the Company filed the Back Forty Project Technical Report Summary on October 26, 2023. Results of the 
work  indicate  a  more  robust  economic  project  with  no  planned  impacts  to  wetlands  that  is  more  protective  of  the 
environment, which should facilitate a successful mine permitting process. The Board continues to evaluate options that 
could lead to the development of the Project.

Non-GAAP Measures  

Throughout this report, we have provided information prepared or calculated according to U.S. GAAP and have 
referenced some non-GAAP performance measures which we believe will assist with understanding the performance of 
our business. These measures are based on precious metal gold equivalent ounces sold and include cash cost before co-
product  credits  per ounce,  total  cash cost after  co-product credits per ounce,  and  total all-in  sustaining  cost per  ounce 
(“AISC”).  Because  the  non-GAAP  performance  measures  do  not  have  any  standardized  meaning  prescribed  by  U.S. 
GAAP,  they  may  not  be  comparable  to  similar  measures  presented  by  other  companies.  Accordingly,  these  measures 
should not be considered in isolation or as a substitute for measures of performance prepared in accordance with U.S. 
GAAP.  These  non-GAAP  measures  are  not  necessarily  indicative  of  operating  profit  or  cash  flow  from  operations  as 
determined under GAAP.  

For financial reporting purposes, we report the sale of base metals as part of our revenue. Revenue generated from 
the sale of base metals in our concentrates is considered a co-product of our gold and silver production for the purpose of 
our total cash cost after co-product credits for our Don David Gold Mine. We periodically review our revenues to ensure 
that our reporting of primary products and co-products remains appropriate. Because we consider copper, lead, and zinc 
to be co-products of our precious metal production, the value of these metals continues to be applied as a reduction to total 
cash costs in our calculation of total cash cost after co-product credits per gold equivalent ounce sold. Gold equivalent is 
determined by taking gold ounces produced and sold, plus silver ounces produced and sold, converted to gold equivalent 
ounces using the gold to silver average realized price ratio for the period. We believe the identification of copper, lead, 
and zinc as co-product credits is appropriate because of their lower individual economic value compared to gold and silver 
and due to the fact that gold and silver are the primary products we intend to produce. 

Total  cash  cost,  after  co-product  credits,  is  a  measure  developed by  the  Gold  Institute  in  an  effort  to  provide  a 
uniform standard for comparison purposes. AISC is calculated based on the current guidance from the World Gold Council. 

 Total cash cost before co-product credits includes all direct and indirect production costs related to our production 
of metals (including mining, milling, and other plant facility costs, royalties, and site general and administrative costs) less 
stock-based compensation allocated to production costs plus treatment and refining costs. 

Total cash cost after co-product credits includes total cash cost before co-product credits, less co-product credits 

(revenues earned from base metals). 

 AISC includes total cash cost after co-product credits plus other costs related to sustaining production, including 
sustaining allocated general and administrative expenses and sustaining capital expenditures. We determined sustaining 
capital expenditures as those capital expenditures that are necessary to maintain current production and execute the current 
mine plan. 

 Cash cost before co-product credits per ounce, total cash cost after co-product credits per ounce, and AISC are 
calculated  by  dividing  the  relevant  costs,  as  determined  using  the  cost  elements  noted  above,  by  precious  metal  gold 
equivalent ounces sold for the periods presented.

Liquidity and Capital Resources  

As of December 31, 2023, our working capital was $15.2 million, a decrease of $6.2 million from $21.4 million at 
December 31, 2022. Our working capital balance at December 31, 2023 reflects a decrease in cash, partially offset by a 
decrease  in  current  liabilities  related  to  income  tax  payable,  accounts  payable,  and  the  contingent  consideration.  The 
decrease of $17.4 million of cash and cash equivalents from December 31, 2022 is attributable to a cash outflow of $12.5 
million for capital investments, as well as a cash outflow of $5.2 million from operating activities for 2023 that includes 
$7.8 million of income tax payments for the tax years 2022 and 2023, exploration investment of $4.2 million in DDGM, 
and $1.6 million of spending on the Back Forty Project optimization work. The cash outflow from operating activities is 
partially the result of higher energy prices due to inflation and the strengthening of the Mexican Peso. Our working capital 
balance fluctuates as we use cash to fund our operations, financing, and investing activities, including exploration and 
mine  development.  We  believe  that  as  a  result  of  our  cash  balances,  the  performance  of  our  current  and  expected 
operations, and current metals prices, we will be able to meet our obligations and other potential cash requirements during 
the next 12 months from the date of this report.  

The actual amount of cash receipts that we receive during the period from operations may vary significantly from 
the planned amounts due to, among other things: (i) unanticipated variations in grade, (ii) unexpected challenges associated 
with our proposed mining plan, (iii) decreases in commodity prices below those used in calculating the estimates shown 
above,  (iv)  variations  in  expected  recoveries,  or  (v)  interruptions  in  mining  at  DDGM.  The  actual  amount  of  cash 
expenditures that we incur during the twelve-month period ending December 31, 2024 may vary significantly from the 
planned amounts and will depend on a number of factors, including, among other things: (i) unexpected challenges in 
operations, including exploration and development, (ii) increases in operating costs above those used in calculating the 
estimates  shown  above,  (iii)  possible  strategic  transactions,  and  (iv)  continued  inflationary  pressure.  Likewise,  if  cash 
expenditures are greater than anticipated or if cash receipts are less than anticipated, we may need to take certain actions 
to adjust our spending over the next twelve months. Although it is not likely, given the current share price, we may also 
utilize the At-The-Market Offering Agreement (“ATM”) program, if necessary. Please see Item 8. Financial Statements 
and Supplementary Data—Note 12. Shareholders’ Equity in for additional information about the ATM. 

Long-term liabilities assumed with the Aquila acquisition, capital requirements to develop the Back Forty Project, 
and potential project financing may have an impact on liquidity in the long term. These long-term liabilities are contingent 
upon  the  Back  Forty  Project  securing  project  financing  and  achieving  commercial  production.  Project  financing 
requirements will not be determined until the Company Board of Directors approves a decision to proceed on the Project. 
The Board continues to evaluate options that could lead to the development of the Project. 

Cash and cash equivalents as of December 31, 2023 decreased to $6.3 million from $23.7 million as of December 
31, 2022, a net decrease in cash of $17.4 million. The decrease is primarily due to the $5.2 million cash outflows from 
operations and the $12.5 million cash spent on investing activities for capital investments, offset by $0.2 million increase 
in value due to the strengthening of the peso. 

Net cash used in operating activities for the years ended December 31, 2023 was $5.2 million, compared to net cash 
provided by operating activities of $14.2 million in 2022. The decrease is mainly attributable to reduced net sales resulting 
from lower mined and processed tonnages, lower grades realized on said tonnages, and lower realized metal prices for 
copper and zinc. Other attributable impacts to production costs included higher inflation and a stronger average Mexican 
Peso in 2023 as compared to 2022 that resulted in increased costs offset by lower mining and processing related costs 
resulting from lower tonnage. 

Net cash used in investing activities for the year ended December 31, 2023 was $12.5 million compared to $19.4 
million during the same period in 2022. The decrease in investing activities is primarily attributable to non-recurring capital 
projects undertaken in 2022 (including efforts to improve stabilization and ventilation of the Don David mine and the 
completion of the filtration plant) and in addition, the lower Back Forty expenses related to the optimization work in 2023, 
as compared to 2022.

Net  cash  used  in  financing  activities  for  the  year  ended  December  31,  2023  was  a  net  outflow  of  $0.1  million 
compared to a net outflow of $3.9 million in 2022. The lower financing costs are attributable to the suspension of the 
dividend program in 2023. 

Off-Balance Sheet Arrangements  

As of December 31, 2023, we have off-balance sheet arrangements related to equipment purchase obligations of 

$0.8 million.  

Accounting Developments  

Recent accounting pronouncements issued have been evaluated and do not presently impact our financial statements 

and supplemental data. 

Critical Accounting Estimates  

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and 
assumptions that affect the reported amount of assets, liabilities, and contingencies at the date of the financial statements, 
as well as the reported amounts of revenues and expenses during the reporting period. As a result, management is required 
to routinely make judgments and estimates about the effects of matters that are inherently uncertain. Actual results may 
differ from these estimates under different conditions or assumptions. The following discussion pertains to accounting 
estimates management believes are most critical to the presentation of our financial position and results of operations that 
require management’s most difficult, subjective, or complex judgments.  

Future Metals Prices 

Metals prices are key components in estimates that determine the valuation of some of our significant assets and 
liabilities, including properties, plant and equipment, deferred tax assets, and certain accounts receivable. Metals prices 
are also an important component in the estimation of reserves. As shown above in Item 1. – Business, metals prices have 
historically been volatile. Gold demand arises primarily from investment and consumer demand. Silver demand arises 
from investment demand, particularly in exchange-traded funds, industrial demand, and consumer demand. Investment 
demand for gold and silver can be influenced by several factors, including: the value of the U.S. dollar and other currencies, 
changing U.S.  budget deficits, widening  availability  of  exchange-traded funds,  interest rate  levels,  the  health of  credit 
markets,  and  inflationary  expectations.  The  investments  in  the  construction  industry,  rising  electrical  and  electronics 
production, and demand for industrial equipment are some of the major factors driving the demand for base metals and 
their prices. 

Mineral Resources and Mineral Reserves 

Critical  estimates  are  inherent  in  the  process  of determining our Mineral  Resources  and  Mineral  Reserves.  Our 
Mineral Resources and Mineral Reserves are affected largely by our assessment of future metals prices, as well as by 
engineering and geological estimates of ore grade, accessibility, and production costs. Metals prices used in estimating our 
Mineral Resources and Mineral Reserves closely approximate the average median consensus prices from analysts as at 
June 2023 for each of the five years starting 2024 through 2028. The consensus prices were based on estimates of 38 
financial institutions compiled by the Company. These consensus prices were subsequently compared to the actual 2023 
closing  spot  price  as  at  September  29,  2023  and  the  36-month  average  as  at  August  28,  2023  and  as  per  published 
exchanges (Comex for precious metals and London Metal Exchange (“LME”) for base metals) to ensure the prices used 
for the Mineral Resources and Mineral Reserves were still considered to be reasonably conservative estimates. Of note, 
the metal price estimates are applied to both the Back Forty Mine Project Technical Report Summary and the DDGM 
Technical Report Summary. Our assessment of Mineral Resources and Mineral Reserves occurs at least annually. Mineral 
Reserves are a key component in the valuation of our property, equipment, mine development, and related depletion and 
depreciation rates. 

Gold Resource Corporation—Management’s Discussion and Analysis of Financial Condition and Results of Operations 
58 

 
 
 
 
Mineral Reserve estimates are used in determining appropriate rates of units-of-production depreciation, with net 
book value of many assets depreciated over remaining estimated reserves. Mineral Resources and Mineral Reserves are 
also key components in forecasts of estimated future cash flows, which we compare to current asset values in an effort to 
ensure that carrying values are reported appropriately, as well as assessment of the recoverability of deferred tax assets 
related  to  expectations  of  future  taxable  income.  Mineral Resources  and  Mineral  Reserves  are  a  culmination  of  many 
estimates and are not guarantees that we will recover the indicated quantities of metals or that we will do so at a profitable 
level. 

Revenue 

Concentrate sales are initially recorded based on 100% of the provisional sales prices, net of treatment and refining 
charges, at the time of delivery to the customer, at which point the performance obligations are satisfied and control of the 
product is transferred to the customer. Adjustments to the provisional sales prices are made to take into account the mark-
to-market changes based on the forward prices of metals until final settlement occurs. The changes in price between the 
provisional sales price and final sales price are considered an embedded derivative that is required to be separated from 
the host contract for accounting purposes. The host contract is the receivable from the sale of the concentrates at the quoted 
metal prices at the time of delivery. The embedded derivative, which does not qualify for hedge accounting, is adjusted to 
market through revenue each period prior to final settlement. Market changes in the prices of metals between the delivery 
and final settlement dates will result in adjustments to revenues related to previously recorded sales of concentrate. Sales 
are recorded net of charges for treatment, refining, smelting losses, and other charges negotiated with the buyer. These 
charges are estimated upon delivery of concentrates based on contractual terms and adjusted to reflect actual charges at 
final settlement. Historically, actual charges have not varied materially from the Company’s initial estimates. 

Doré sales are recognized upon the satisfaction of performance obligations, which occurs when price and quantity 

are agreed upon with the customer. Doré sales are recorded using quoted metal prices, net of refining charges.  

Depreciation and Amortization 

Capitalized costs are depreciated or amortized using the straight-line method or unit-of-production (“UOP”) method 
at rates sufficient to depreciate such costs over the shorter of estimated productive lives of such assets or the useful life of 
the  individual  assets.  Significant  judgment  is  involved  in  the  determination  of  the  estimated  life  of  the  assets.  The 
Company’s estimates for Mineral Reserves is used in determining our UOP rates. The Company’s estimates of proven and 
probable  ore  reserves  may  change,  possibly  in  the  near  term,  resulting  in  changes  to  depreciation,  depletion,  and 
amortization rates in future reporting periods. Productive lives of the assets range from 1 to 10 years, but do not exceed 
the useful life of the individual asset. Please see Item 8. Financial Statements and Supplementary Data—Note 1. Nature 
of Operations and Summary of Significant Accounting Policies for depreciation rates of major asset categories.

Carrying Value of Stockpiles 

Stockpiles  represent  ore  that  has  been  extracted  from  the  mine  and  is  available  for  further  processing.  Mine 
sequencing may result in mining material at a faster rate than can be processed. We generally process the highest ore grade 
material first to maximize metal production; however, a blend of gold ore stockpiles may be processed to balance hardness 
and/or metallurgy in order to maximize throughput and recovery. Processing of lower grade stockpiled ore may continue 
after mining operations are completed. Stockpiles are measured by estimating the number of tonnes added and removed 
from the stockpile, the number of contained ounces (based on assay data), and the estimated metallurgical recovery rates. 
Stockpile  ore  tonnages  are  verified  by  periodic  surveys.  Costs  are  added  to  stockpiles  based  on  current  mining  costs, 
including  applicable  overhead,  depreciation,  and  amortization  relating  to  mining  operations  and  removed  at  each 
stockpile’s average cost per recoverable unit as material is processed. 

We record stockpiles at the lower of average cost or net realizable value, and carrying values are evaluated at least 
quarterly. Net realizable value represents the estimated future sales price based on short-term and long-term metals price 
assumptions that are applied to expected short-term (12 months or less) and long-term sales from stockpiles, less estimated 
costs to complete production and bring the product to sale. The primary factors that influence the need to record write-
downs of stockpiles include declines in short-term or long-term metals prices, increases in costs of production inputs such 
as labor, fuel and energy, materials and supplies, as well as realized ore grades and recovery rates. 

Other assumptions include future operating and capital costs, metal recoveries, production levels, commodity prices, 
Mineral Resource and Mineral Reserve quantities, engineering data, and other factors unique to each operation based on 
the life of mine plans. If short-term and long-term commodity prices decrease, estimated future processing costs increase, 
or other negative factors occur, it may be necessary to record a write-down of ore on stockpiles. A high degree of judgment 
is involved in determining such assumptions and estimates and no assurance can be given that actual results will not differ 
significantly from those estimates and assumptions. 

Impairment of Long-Lived Assets 

We evaluate the carrying value of long-lived assets to be held and used using a fair-value based approach when 
events and circumstances indicate that the related carrying amount of our assets may not be recoverable. The economic 
environment  and  commodity  prices  may  be  considered  as  impairment  indicators  for  the  purposes  of these  impairment 
assessments. In accordance with U.S. GAAP, the carrying value of a long-lived asset or asset group is considered impaired 
when the anticipated undiscounted cash flows from such asset or asset group are less than its carrying value. In that event, 
a loss will be recorded in our Consolidated Statements of Operations based on the difference between book value and the 
estimated fair value of the asset or asset group computed using discounted estimated future cash flows, or the application 
of an expected fair value technique in the absence of an observable market price. Future cash flows include estimates of 
recoverable  quantities  to  be  produced  from  estimated  Mineral  Resources  and  Mineral  Reserves,  commodity  prices 
(considering current and historical prices, price trends, and related factors), production quantities, production costs, and 
capital expenditures, all based on life-of-mine plans and projections. In estimating future cash flows, assets are grouped at 
the lowest level for which identifiable cash flows exist that are largely independent of cash flows from other asset groups. 
It is possible that actual future cash flows will be significantly different than the estimates, as actual future quantities of 
recoverable  minerals,  gold  and  other  commodity  prices,  production  levels  and  costs,  and  capital  are  each  subject  to 
significant risks and uncertainties. 

Asset Retirement Obligation/Reclamation and Remediation Costs 

Our mining and exploration activities are subject to various laws and regulations, including legal and contractual 
obligations  to  reclaim,  remediate,  or  otherwise  restore  properties  at  the  time  the  property  is  removed  from  service. 
Accounting for reclamation and remediation obligations requires management to make estimates of the future costs that 
we will incur to complete the work required to comply with existing laws and regulations. Actual costs may differ from 
the amounts estimated. Reclamation costs are allocated to expense over the life of the related assets and are periodically 
adjusted to reflect changes in the estimated present value resulting from the passage of time and revisions to the estimates 

Gold Resource Corporation—Management’s Discussion and Analysis of Financial Condition and Results of Operations 
60 

 
 
 
 
of either the timing or amount of the reclamation and remediation costs. Also, future changes to environmental laws and 
regulations could increase the extent of reclamation and remediation work required. 

Stock-based Compensation 

The  Company  accounts  for  stock-based  employee  compensation  plans  under  the  fair  value  recognition  and 
measurement provisions in accordance with applicable accounting standards, which require all stock-based payments to 
employees,  including  grants  of  stock  options,  restricted  stock  units  (“RSUs”),  performance  share  units  (“PSUs”),  and 
deferred share units (“DSUs”) to be measured based on the grant date fair value of the awards. The resulting expense is 
generally recognized on a straight-line basis over the period during which the employee is required to perform service in 
exchange  for  the  award.  For  stock-based  employee  compensation  that  is  expected  to  be  settled  in  cash,  a  liability  is 
established, and a quarterly mark-to-market adjustment is applied based on current stock price. 

Stock-based  compensation  expense  is  recorded  net  of  estimated  forfeitures  in  our  Consolidated  Statements  of 
Operations, and it is recorded for only those stock-based awards that we expect to vest. We estimate the forfeiture rate 
based on historical forfeitures of equity awards and adjust the rate to reflect changes in facts and circumstances, if any. 
We will revise our estimated forfeiture rate if actual forfeitures differ from our initial estimates. 

Income Taxes  

In  preparing  our  consolidated financial  statements,  we  estimate  the  actual  amount of  taxes  currently payable or 
receivable,  as  well  as  deferred  tax  assets  and  liabilities  attributable  to  temporary  differences  between  the  financial 
statement carrying amounts of existing assets and liabilities and their respective tax bases. Deferred income tax assets and 
liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which these temporary 
differences are expected to be recovered or settled. Changes in deferred tax assets and liabilities generally have a direct 
impact on earnings in the period of the changes. Mining taxes represent federal and state taxes levied on mining operations. 
As the mining taxes are calculated as a percentage of mining profits, we classify them as income taxes. Where applicable 
tax laws and regulations are either unclear or subject to varying interpretations, it is possible that changes in these estimates 
could occur that materially affect the amounts of deferred income tax assets and liabilities recorded in the consolidated 
financial statements. 

Each period, we evaluate the likelihood of whether some portion or all of each deferred tax asset will be realized 
and provide a valuation allowance for those deferred tax assets for which it is more likely than not that the related benefits 
will not be realized. When evaluating our valuation allowance, we consider historical and future expected levels of taxable 
income, the pattern and timing of reversals of taxable temporary timing differences that give rise to deferred tax liabilities, 
and tax planning initiatives. Levels of future taxable income are affected by, among other things, market gold and silver 
prices, production costs, quantities of Mineral Resources and Mineral Reserves, interest rates, federal and local legislation, 
and foreign currency exchange rates. If we determine that all or a portion of the deferred tax assets will not be realized, a 
valuation  allowance  will  be  recorded  with  a  charge  to  income  tax  expense.  Conversely,  if  we  determine  that  we  will 
ultimately be able to realize all or a portion of the related benefits for which a valuation allowance has been provided, all 
or a portion of the related valuation allowance will be reduced with a credit to income tax expense. 

In  addition,  the  calculation  of  income  tax  expense  involves  significant  management  estimation  and  judgment 
involving a number of assumptions. In determining these amounts, management interprets tax legislation in each of the 
jurisdictions  in  which  we  operate  and  makes  estimates  of  the  expected  timing  of  the  reversal  of  future  tax  assets  and 
liabilities. We make assumptions about future earnings, tax planning strategies, and the extent to which potential future 
tax  benefits  will  be  used.  We  are  also  subject  to  assessments  by  various  taxation  authorities,  which  may  interpret  tax 
legislation differently, which could affect the final amount or the timing of tax payments. 

In October 2023, the Company received a notification from the Mexican Tax Administration Services (“SAT”) with 
a sanction of 331 million pesos (approximately $19.5 million) as the result of a 2015 tax audit that began in 2021. The 
2015 tax audit performed by SAT encompassed various tax aspects, including but not limited to intercompany transactions,

mining royalty tax, and extraordinary mining tax. Management is in process of disputing this tax notification and sent a 
letter of protest to the tax authorities along with providing all requested documentation. Management intends to use all 
legal avenues of protest, including filing a lawsuit with the Mexico court system if needed, to see that these adjustments 
are removed. Management believes the 2015 tax return was prepared correctly, and that as of December 31, 2023, the 
Company has no liability. Please also see Item 8. Financial Statements and Supplementary Data—Note 4. Income Taxes. 

ITEM 7A. 

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK  

Our  exposure  to  market  risks  includes,  but  is  not  limited  to,  the  following  risks:  changes  in  commodity  prices, 
foreign currency exchange rates, provisional sales contract risks, changes in interest rates, and equity price risks. We do 
not use derivative financial instruments as part of an overall strategy to manage market risk; however, we may consider 
such arrangements in the future as we evaluate our business and financial strategy. 

Commodity Price Risk  

The results of our operations depend in large part upon the market prices of gold, silver, and base metal prices of 
copper, lead, and zinc. Gold and silver prices fluctuate widely and are affected by numerous factors beyond our control. 
The level of interest rates, the rate of inflation, the state of the global or national economies, the stability of exchange rates, 
the  world  supply  of  and  demand  for  gold,  silver,  and  other  metals,  among  other  factors,  can  all  cause  significant 
fluctuations  in  commodity  prices.  Such  external  economic  factors  are  in  turn  influenced  by  changes  in  international 
investment patterns, monetary systems, and political developments. The price of gold and silver has fluctuated widely in 
recent years, and future price declines could cause a mineral project to become uneconomic, thereby having a material 
adverse effect on our business and financial condition. We have not entered into derivative contracts to protect the selling 
price for gold or silver. We may in the future more actively manage our exposure through derivative contracts or other 
commodity price risk management programs. 

Effective  May  18,  2021,  the  Company  entered  into  a  Trading  Agreement  with  Auramet  International  LLC  that 
govern  non-exchange  traded,  over-the-counter,  spot,  forward,  and  option  transactions  on  both  a  deliverable  and  non-
deliverable basis involving various metals and currencies. Subsequently, the Company entered into zinc zero cost collars. 
These  derivatives  are  not  designated  as  hedges.  The  zero  cost  collars  were  used  to  manage  the  Company’s  near-term 
exposure to cash flow variability from zinc price risks; however, the current zinc program concluded on December 21, 
2022. We do not currently use financial instruments with respect to any of the other base metal production either. 

In addition to materially adversely affecting our reserve estimates, results of operations, and our financial condition, 
declining gold and silver prices could require a reassessment of the feasibility of a project. Even if a project is ultimately 
determined to be economically viable, the need to conduct such a reassessment may cause delays in the implementation 
of a project. 

Foreign Currency Risk  

Foreign currency exchange rate fluctuations can increase or decrease our costs to the extent that we pay costs in 
currencies other than the U.S. dollar. We are primarily impacted by Mexican peso rate changes relative to the U.S. Dollar, 
as we incur approximately 55-60% of costs in peso in Mexico. When the value of the peso rises in relation to the U.S. 
Dollar, some of our costs in Mexico may increase, thus affecting our operating results. Alternatively, when the value of 
the peso drops in relation to the U.S. Dollar, peso-denominated costs in Mexico will decrease in U.S. Dollar terms. These 
fluctuations do not impact our revenues since we sell our metals in U.S. dollars. Future fluctuations may give rise to foreign 
currency exposure, which may affect our financial results. 

As of December 31, 2023, we held 0.9 million Mexican Pesos ($0.1 million) and 0.2 million Canadian Dollars ($0.1 
million). We have not utilized market-risk sensitive instruments to manage our exposure to foreign currency exchange 
rates but may in the future actively manage our exposure to foreign currency exchange rate risk.

Provisional Sales Contract Risk 

We enter into concentrate sales contracts which, in general, provide for a provisional payment to us based upon 
provisional assays and prices. The provisionally priced sales contracts contain an embedded derivative that is required to 
be  separated  from  the  host  contract  for  accounting  purposes.  The  host  contract  is  the  receivable  from  the  sale  of 
concentrates determined at the quoted metal prices at the time of shipment. The embedded derivative, which does not 
qualify for hedge accounting, is adjusted to market through revenue each period prior to settlement. Changes in the prices 
of metals between the shipment and the final settlement date will result in adjustments to revenues related to the sales of 
concentrate previously recorded upon shipment. Please see Item 8. Financial Statements and Supplementary Data—Note 
13. Derivatives for additional information. 

Interest Rate Risk  

None.  

 Equity Price Risk  

We have in the past, and may in the future, seek to acquire additional funding by sale of common stock and other 
equity. The price of our common stock has been volatile in the past and may also be volatile in the future. As a result, there 
is a risk that we may not be able to sell our common stock at an acceptable price should the need for new equity funding 
arise.

Shareholders and Board of Directors 
Gold Resource Corporation 
Denver, Colorado 

Opinion on the Consolidated Financial Statements 

We  have  audited  the  accompanying  consolidated  balance  sheets  of  Gold  Resource  Corporation  (the 
“Company”)  as  of  December  31,  2023  and  2022,  the  related  consolidated  statements  of  operations, 
changes in shareholders’ equity, and cash flows for each of the years then ended, and the related notes 
(collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated 
financial statements present fairly, in all material respects, the financial position of the Company at 
December 31, 2023 and 2022, and the results of its operations and its cash flows for the years then 
ended, in conformity with accounting principles generally accepted in the United States of America. 

Basis for Opinion 

These  consolidated  financial  statements  are  the  responsibility  of  the  Company’s  management.  Our 
responsibility is to express an opinion on the Company’s consolidated financial statements based on our 
audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board 
(United  States)  (“PCAOB”)  and  are  required  to  be  independent  with  respect  to  the  Company  in 
accordance  with  the  U.S.  federal  securities  laws  and  the  applicable  rules  and  regulations  of  the 
Securities and Exchange Commission and the PCAOB. 

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that 
we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial 
statements  are  free  of  material  misstatement,  whether  due  to  error  or  fraud.  The  Company  is  not 
required  to  have,  nor  were  we  engaged  to  perform,  an  audit  of  its  internal  control  over  financial 
reporting. As part of our audits, we are required to obtain an understanding of internal control over 
financial  reporting  but  not  for  the  purpose  of  expressing  an  opinion  on  the  effectiveness  of  the 
Company’s internal control over financial reporting. Accordingly, we express no such opinion. 

Our  audits  included  performing  procedures  to  assess  the  risks  of  material  misstatement  of  the 
consolidated  financial  statements,  whether  due  to  error  or  fraud,  and  performing  procedures  that 
respond to those risks. Such procedures included examining, on a test basis, evidence regarding the 
amounts and disclosures in the consolidated financial statements. Our audits also included evaluating 
the accounting principles used and significant estimates made by management, as well as evaluating 
the overall presentation of the consolidated financial statements. We believe that our audits provide a 
reasonable basis for our opinion. 

Critical Audit Matter 

The critical audit matter communicated below is a matter arising from the current period audit of the 
consolidated financial statements that was communicated or required to be communicated to the audit 
committee  and  that:  (1)  relates  to  accounts  or  disclosures  that  are  material  to  the  consolidated 
financial statements and (2) involved our especially challenging, subjective, or complex judgments. The 
communication of the critical audit matter does not alter in any way our opinion on the consolidated 
financial statements, taken as a whole, and we are not, by communicating the critical audit matter 
below,  providing  separate  opinions  on  the  critical  audit  matter  or  on  the  accounts  or  disclosures  to 
which it relates.

Evaluation of Going Concern 

As described in Note 9 of the Company’s consolidated financial statements, the Company’s liabilities 
under  its  gold  and  silver  stream  agreements  were  approximately  $21  million  and  $24  million, 
respectively, as of December 31, 2023. The stream agreements contain certain customary provisions 
regarding  default  and  security,  including  certain  operational  covenants.  In  the  event  that  the 
Company’s subsidiary defaults under the stream agreements, it may be required to repay the deposit 
plus accumulated interest. The Company obtained  deferral to 2026 of certain operational covenants 
that  were  previously  due  in  2024,  as  more  fully  described  in  Note  9.  Additionally,  the  Company’s 
revenues declined by $41 million in 2023 as compared to 2022. Should the Company default under the 
terms of these operational covenants or otherwise be unable to fund its obligations as they become 
due, these conditions could raise substantial doubt regarding its ability to continue as a going concern.  

We identified management’s evaluation regarding the Company’s ability to continue as a going concern 
as a critical audit matter due to the significant judgments and assumptions used by management in (i) 
forecasting compliance with operational covenants in stream agreements, (ii) preparing its forecast of 
sources  of  cash  and  expenditures,  and  (iii)  expectations  of  future  metals  prices.  Auditing  these 
estimates  and  assumptions  involved  especially  challenging  auditor  judgment  due  to  the  nature  and 
extent of audit evidence and effort required to address these matters.  

The primary procedures we performed to address this critical audit matter included: 

  Obtaining the amendments to the Company’s stream agreements which deferred the compliance 

date of certain operational covenants. 

  Testing compliance with covenants in the stream agreements for a period of one year after the 

date the consolidated financial statements are issued. 

  Evaluating the appropriateness of management’s forecast of sources of cash and expenditures 
by  comparing  to  historical  forecasts  and  actual  results,  and  certain  planned  operational 
activities. 

  Evaluating  the  appropriateness  of  expected  future  metals  prices  by  comparing  to  historical 

results and published forecasted industry data.

(1)  Cash dividends declared and paid per share was $0.04 for 2022. On February 13, 2023, the Company announced the suspension of future quarterly dividends, thus no cash dividends were declared and 

paid in 2023. 

(2)  Aquila formerly issued shares related to RebGold/BacTech Mining Arrangement Agreement that expired in 2020. As these shares were not redeemed prior to expiration, the shares should have been struck 

by Aquila’s transfer agent prior to issuing GRC shares on December 10, 2021 in connection with the acquisition by GRC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS  

December 31, 2023 and 2022 

1. Nature of Operations and Summary of Significant Accounting Policies  

Nature of Operations 

Gold Resource Corporation (the “Company”) was organized under the laws of the State of Colorado on August 
24, 1998. The Company is a producer of doré containing gold and silver and metal concentrates that contain gold, silver, 
copper, lead, and zinc in Oaxaca, Mexico. The Company also has 100% interest in the Back Forty Project, an advanced 
Exploration Stage Property, located in Menominee County, Michigan, USA. 

Significant Accounting Policies  

Basis of Presentation  

The  consolidated  financial  statements  included  herein  are  expressed  in  United  States  dollars  and  conform  to 
accounting principles generally accepted in the United States of America (“U.S. GAAP”). The consolidated financial 
statements include the accounts of the Company, its Mexican subsidiary, Don David Gold Mexico S.A. de C.V., and 
Aquila Resources Inc (“Aquila) and its subsidiaries. Intercompany accounts and transactions have been eliminated in 
consolidation. 

Segment Reporting 

The Company has organized its operations into three geographic regions. The geographic regions include Oaxaca, 
Mexico, Michigan, U.S.A., and Corporate and Other. Oaxaca, Mexico represents the Company’s only production stage 
property. Michigan, U.S.A. is an advanced exploration stage property. The Company’s business activities that are not 
considered production stage or advanced exploration stage properties are included in Corporate and Other. Please see 
Note 21—Segment Reporting below for additional information. 

Use of Estimates 

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates 
and assumptions that affect the reported amount of assets and liabilities, the disclosure of contingent assets and liabilities 
at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting periods. 
The more significant areas requiring the use of management estimates and assumptions relate to Mineral Resources and 
Mineral  Reserves  that  are  the  basis  for  future  cash  flow  estimates  utilized  in  impairment  calculations  and  units-of-
production  depreciation  calculations;  future  metal  prices;  environmental  remediation,  reclamation  and  closure 
obligations; estimates of recoverable gold and other minerals in stockpiles; write-downs of inventory stockpiles to net 
realizable value; valuation allowances for deferred tax assets and liabilities; valuation of contingent considerations and 
gold and silver stream agreements; provisional amounts related to income tax effects of newly enacted tax laws; and 
stock-based compensation. Management routinely makes judgments and estimates about the effects of matters that are 
inherently uncertain and bases its estimates and judgments on historical experience and on various other factors that are 
believed to be reasonable under the circumstances. Actual results could differ from these estimates. 

Revisions of Previously Issued Financial Statements for Correction of Immaterial Errors  

In connection with the preparation of the Company’s financial statements for the period ended September 30, 
2023, the Company’s management identified an immaterial error in prior period financial statements, whereby deferred 

Gold Resource Corporation

tax liabilities and deferred tax assets attributable to different tax-paying components of the entity or to different tax 
jurisdictions were incorrectly offset. The Company has corrected the consolidated balance sheets as of December 31, 
2022, for this immaterial error. The effects of these revisions are as follows.

Cash and cash equivalents consist of all cash balances and highly liquid investments with a remaining maturity 
of three months or less when purchased. Cash held in Mexican Pesos or Canadian Dollars is converted to U.S. Dollars 
at the closing exchange rate at year end. 

Accounts Receivable, net 

Accounts receivable consists of trade receivables, which are recorded net of allowance for credit losses from the 
sale of doré and metals concentrates, as well as net of an embedded derivative based on mark-to-market adjustments for 
outstanding  provisional  invoices  based  on  forward  metal  prices.  Please  see  Item  8.  Financial  Statements  and 
Supplementary Data—Note 13. Derivatives and Item 8. Financial Statements and Supplementary Data—Note 19. Fair 
Value Measurement for additional information related to the embedded derivative. As of both December 31, 2023 and 
2022, the allowance for credit losses was nil.

Inventories 

The major inventory categories are set forth below: 

Stockpile  Inventories:  Stockpile  inventories  represent  ore  that  has  been  mined  and  is  available  for  further 
processing.  Stockpiles  are  measured  by  estimating  the  number  of  tonnes  added  and  removed  from  the  stockpile,  an 
estimate of the contained metals (based on assay data), and the estimated metallurgical recovery rates. Costs are allocated 
to stockpiles based on relative values of material stockpiled and processed using current mining costs incurred, including 
applicable  overhead,  depreciation,  and  amortization  relating  to  mining  operations.  Material  is  removed  at  each 
stockpile’s  average  cost  per  tonne.  Stockpiles  are  carried  at  the  lower  of  average  cost  or  net  realizable  value.  Net 
realizable value represents the estimated future sales price of the product based on current and long-term metals prices, 
less the estimated costs to complete production and to bring the product to sale. 

Concentrate  Inventories:  Concentrate  inventories  include  metal  concentrates  located  either  at  the  Company’s 
facilities or in transit to its customer’s port. Inventories consist of copper, lead, and zinc metal concentrates, which also 
contain  gold  and  silver  mineralization.  Concentrate  inventories  are  carried  at  the  lower  of  cost  of  production  or  net 
realizable value based on current metals prices. 

Doré Inventory: Doré includes gold and silver doré bars held at the Company’s facility. Doré inventories are 

carried at the lower of cost of production or net realizable value based on current metals prices. 

Materials and Supplies Inventories: Materials and supplies inventories consist of chemical reagents, parts, fuels, 
and other materials and supplies. Cost includes applicable taxes and freight. Materials and supplies inventory is carried 
at the lower of average cost or net realizable value. 

Write-downs  of  inventory,  when  needed,  are  charged  to  production  costs  on  the  Consolidated  Statements  of 

Operations. 

Property, Plant, and Mine Development 

Land  and  Mineral  Interests: The  costs  of  acquiring  land,  mineral  rights,  and  mineral  interests  are  considered 
tangible  assets.  Administrative  and  holding  costs  to  maintain  an  exploration  property  are  expensed  as  incurred.  If  a 
mineable mineral deposit is discovered, such capitalized costs are amortized when production begins using the units of 
production (“UOP”) method. If no mineable mineral deposit is discovered, or such rights are otherwise determined to 
have diminished value, costs are expensed in the period in which this determination is made.  

Mine Development: This includes the cost of engineering and metallurgical studies; drilling and other related 
costs  to  delineate  an  ore  body;  and  the  cost  of  building  access  ways,  shafts,  lateral  access,  drifts,  ramps,  and  other 
infrastructure. Costs incurred before mineralization is classified as Mineral Resources are expensed and classified as 
exploration expenses. Capitalization of mine development project costs that meet the definition of an asset begins once 
mineralization is classified as Mineral Resources. 

Drilling costs incurred during the production phase for operational ore control are recorded as mine development 

and amortized using UOP. All other drilling and related costs are expensed as incurred. 

Mine development costs are amortized using the UOP method based on estimated recoverable ounces in Mineral 

Reserves.  

Property and Equipment: All items of property and equipment are carried at cost. Normal maintenance and repairs 
are expensed as incurred, while expenditures for major maintenance and improvements are capitalized. Gains or losses 
on disposition are recognized in other expense, net. 

Gold Resource Corporation 
73 

 
 
Construction in Progress: Expenditures for new facilities or equipment are capitalized and recorded at cost. Once 
completed  and  ready  for  its  intended  use,  the  asset  is  transferred  to  property  and  equipment  to  be  depreciated  or 
amortized. 

Depreciation and Amortization: Capitalized costs are depreciated or amortized using the straight-line or UOP 
method at rates sufficient to depreciate such costs over the shorter of estimated productive lives of such assets or the 
useful life of the individual assets. The estimates for Mineral Reserves are a key component in determining the UOP 
depreciation rates. The estimates of Mineral Reserves may change, possibly in the near term, resulting in significant 
changes to depreciation and amortization rates in future reporting periods. The following are the estimated economic 
lives of depreciable assets: 

Asset retirement costs 
Furniture, computer and office equipment 
Light vehicles and other mobile equipment 
Machinery and equipment  
Mill facilities and related infrastructure 
Mine development and mineral interests 
Buildings and infrastructure 

Impairment of Long-Lived Assets 

Range of Lives   

  UOP 
  3 to 10 years 
  4 years 
  UOP to 8 years 
  UOP 
  UOP 
  UOP to 4 years 

The Company evaluates its long-lived assets for impairment when events or changes in circumstances indicate 
that the related carrying amounts may not be recoverable. Asset impairment is considered to exist if the total estimated 
future cash flows on an undiscounted basis are less than the carrying amount of the asset. If an impairment is indicated, 
a determination is made whether an impairment has occurred. Impairment losses are measured either 1) as the excess of 
carrying value over the total discounted estimated future cash flows, or 2) as the excess of carrying value over the fair 
value,  using  the  expected  fair  value  technique  in  the  absence  of  an  observable  market  price.  Losses  are  charged  to 
expense on the Company’s Consolidated Statements of Operations. In estimating future cash flows, assets are grouped 
at the lowest level for which there are identifiable cash flows that are largely independent of future cash flows from 
other asset groups.  

Existing Mineral Resources and Mineral Reserves are included when estimating the fair value in determining 
whether the assets are impaired. The Company’s estimates of future cash flows are based on numerous assumptions, 
including  expected  gold  and  other  commodity  prices,  production  levels  and  costs,  processing  recoveries,  capital 
requirements, and estimated salvage values. It is possible that actual future cash flows will be significantly different 
from the estimates, as actual future quantities of recoverable minerals, gold and other commodity prices, production 
levels and costs, and capital requirements are each subject to significant risks and uncertainties. 

Fair Value of Financial Instruments 

The recorded amounts of cash and cash equivalents, receivables from provisional concentrate sales, and accounts 
payable approximate fair value because of the short maturity of those instruments. The recorded amount for the equity 
investment in the common shares of Maritime is based on the closing share price of MAE.V on TSX-V. The company 
elected the fair value measurement option as the measurement basis for the equity investment in the common shares of 
Green Light Metals.

Treasury  stock  represents  shares of  the  Company’s  common  stock which have been repurchased on  the  open 
market at the prevailing market price at the time of purchase and have not been canceled. Treasury stock is shown at 
cost as a separate component of shareholders’ equity.  

Revenue Recognition  

The Company recognizes revenue from doré and concentrate sales. 

Doré  sales:  Doré  sales  are  recognized  upon  the  satisfaction  of  performance  obligations,  which  occurs  upon 
delivery of doré and when the price and quantity are agreed with the customer. Doré sales are recorded using quoted 
metal prices, net of refining charges.  

Concentrate sales: Concentrate sales are initially recorded based on 100% of the provisional sales prices, net of 
treatment and refining charges, at the time of delivery to the customer, at which point the performance obligations are 
satisfied and control of the product is transferred to the customer. Adjustments to the provisional sales prices are made 
to take into account the mark-to-market changes based on the forward prices of metals until final settlement occurs. The 
changes in price between the provisional sales price and final sales price are considered an embedded derivative that is 
required to be separated from the host contract for accounting purposes. The host contract is the receivable from the sale 
of the concentrates at the quoted metal prices at the time of delivery. The embedded derivative, which does not qualify 
for hedge accounting, is adjusted to market through revenue each period prior to final settlement. Market changes in the 
prices  of  metals  between  the  delivery  and  final  settlement  dates  will  result  in  adjustments  to  revenues  related  to 
previously recorded sales of concentrate. Sales are recorded net of charges for treatment, refining, smelting losses, and 
other charges negotiated with the buyer. These charges are estimated upon delivery of concentrates based on contractual 
terms and adjusted to reflect actual charges at final settlement, which normally occurs within three months. Historically, 
actual charges have not varied materially from the Company’s initial estimates. 

Production Costs 

Production costs include labor and benefits, royalties, concentrate and doré shipping costs, mining costs, fuel and 
lubricants,  legal  and  professional  fees  related  to  mine  operations,  stock-based  compensation  attributable  to  mine 
workers,  materials  and  supplies,  repairs  and  maintenance,  explosives,  site  support,  housing  and  food,  insurance, 
reagents, travel, medical services, security equipment, office rent, tools, and other costs that support mining operations. 

Exploration Costs 

Exploration costs are charged to expense as incurred. Costs to identify new Mineral Resources and to evaluate 
potential  Mineral  Resources  are  considered  exploration  costs.  Exploration  activities  conducted  within  the  defined 
Mineral Resources are capitalized.  

Stock-Based Compensation 

The  Company  accounts  for  stock-based  compensation  under  the  fair  value  recognition  and  measurement 
provisions  of  U.S.  GAAP.  Those  provisions  require  all  stock-based  payments,  including  grants  of  stock  options, 
restricted stock units (“RSUs”), performance share units (“PSUs”), and deferred share units (“DSUs”) to be measured 
based on the grant date fair value of the awards, with the resulting expense generally recognized on a straight-line basis 
in the Consolidated Statements of Operations over the period during which services are performed in exchange for the 
award. The majority of the awards are earned over a service period of three years. DSUs are earned immediately at grant 
and are expected to be paid out in cash in the future. PSUs and DSUs are considered liability instruments and marked-
to-market  each  reporting  period.  The  Company's  estimates  may  be  impacted  by  certain  variables  including,  but  not 
limited to, stock price volatility, employee stock option exercise behaviors, additional stock option grants, and estimates 
of forfeitures.

Reclamation and Remediation Costs 

Reclamation costs are allocated to expense over the life of the related assets and are periodically adjusted to reflect 
changes in the estimated present value resulting from the passage of time and revisions to the estimates of either the 
timing  or  amount  of  the  reclamation  and  remediation  costs.  Reclamation  obligations  are  based  in  part  on  when  the 
spending for an existing environmental disturbance will occur. The Company reviews the reclamation obligation at least 
on an annual basis. 

In 2014, the Company became a production stage company and therefore, started capitalizing asset retirement 
costs along with the asset retirement obligation. Please see Item 8. Financial Statements and Supplementary Data—Note 
10. Reclamation and Remediation in for additional information. 

Accounting for reclamation and remediation obligations requires management to make estimates unique to each 
mining operation of the future costs expected to be incurred to complete the reclamation and remediation work required 
to comply with existing laws and regulations. Actual costs  incurred in future periods could differ from the amounts 
estimated. Additionally, future changes to environmental laws and regulations could increase the extent of reclamation 
and  remediation  work  required.  Any  such  increases  in  future  costs  could  materially  impact  the  amounts  charged  to 
operations for reclamation and remediation.  

Accumulated Other Comprehensive Loss 

Accumulated other comprehensive loss is presented in the Consolidated Statements of Changes in Shareholders’ 
Equity. Accumulated other comprehensive loss is composed of foreign currency translation adjustment effects related 
to the historical adjustment when the functional currency was the Mexican peso for our Mexico subsidiary. This loss 
will remain on our Consolidated Balance Sheets until the sale or dissolution of our Mexico subsidiary. 

Income and Mining Royalty Taxes 

Income and Mining Royalty Taxes are computed using the asset and liability method. Deferred income taxes 
reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial 
and tax reporting purposes and the effect of net operating loss and foreign tax credit carryforwards using enacted tax 
rates  in  effect  in  the  years  in  which  the  differences  are  expected  to  reverse.  Deferred  tax  assets  and  liabilities  are 
evaluated to determine if it is more likely than not that they will be realized. Deferred tax liabilities and deferred tax 
assets attributable to different tax-paying components of the entity or to different tax jurisdictions are not netted against 
each  other.  Please  see  Item  8.  Financial  Statements  and  Supplementary  Data—Note  4.  Income  Taxes  for  additional 
information. 

Net Loss Per Share 

Basic loss per share is calculated based on the weighted average number of common shares outstanding for the 
period. Diluted loss per share reflects the dilution that could occur if potentially dilutive securities, as determined using 
the  treasury  stock  method,  are  converted  into  common  stock.  Potentially  dilutive  securities  are  excluded  from  the 
calculation when their inclusion would be anti-dilutive, such as periods when a net loss is reported or when the exercise 
price of the instrument exceeds the average fair market value of the underlying common stock.  

Foreign Currency 

The functional currency for all of the Company’s subsidiaries is the United States dollar (“U.S. dollar”).

Concentration of Credit Risk  

The  Company  has  considered  and  assessed  the  credit  risk  resulting  from  its  concentrate  sales  and  doré  sales 
arrangements with its customers. In the event that the Company’s relationships with its customers are interrupted for 
any reason, the Company believes that it would be able to locate another entity to purchase its metals concentrates and 
doré  bars;  however,  any  interruption  could  temporarily  disrupt  the  Company’s  sale  of  its  products  and  materially 
adversely affect operating results. 

Currently 100% of the Company’s total net sales from operations are coming from the Arista and Alta Gracia 
mines at DDGM, the Company’s Oaxaca, Mexico business segment. Sales from significant customers as a percentage 
of sales for the years ended December 31, 2023 and 2022 were the following:

Some  of  the  Company’s  operating  cash  balances  are  maintained  in  accounts  that  currently  exceed  federally 
insured limits. The Company believes that the financial strength of the depositing institutions mitigates the underlying 
risk of loss. To date, these concentrations of credit risk have not had a significant impact on the Company’s financial 
position or results of operations.  

Streaming Liabilities  

The Company presents the gold and silver streaming liabilities initially at fair value and subsequently accreted 
using a discount rate and risk factor probabilities. The discount rate is the Company’s estimated borrowing rate, and the 
probabilities consider the completion of the feasibility study, obtaining necessary permits, and the completion of the 
mine facilities. The adjustment in the value is the accretion of interest, which is included in other expense, net.

In the fourth quarter of 2023, the Company completed a study of the Internal Revenue Code section 382 (“382”) 
net operating loss limitations related to ownership changes in connection with the Back Forty Project acquisition. The 
study found that approximately $45.1 million of federal net operating losses and $12.3 million of Michigan net operating 
losses would be subject to potential limitation under 382. The study also concluded that, of those losses, $30.8 million 
of federal losses and $35.9 million of Michigan losses would be unable to offset future taxable income by the Company 
due to loss limitations under 382 and loss carryforward expirations. The annual limitation for the Company under 382 
is $1.3 million.

In accordance with ASC 740, the Company presents deferred tax assets net of its deferred tax liabilities on its 
Consolidated Balance Sheets on a jurisdictional basis. The net deferred tax liability of $0.8 million as of December 31,

million deferred tax asset related to Don David Gold Mine S.A. de C.V. (“DDGM”) in Mexico. No net deferred tax 
balances exist in Canada due to the existence of a full valuation allowance. 

The Company evaluates the evidence available to determine whether a valuation allowance is required on deferred 
tax assets. As of December 31, 2023, the Company determined that a valuation allowance of $28.3 million was necessary 
due to the uncertain utilization of specific deferred tax assets, primarily net operating loss carryforwards, with $18.8 
million in U.S. and $9.5 million in Canada; $19.5 million of the total valuation allowance of $28.3 million is related to 
Aquila in the U.S. and Canada. As of December 31, 2022, the Company determined that a valuation allowance of $31.8 
million  was  necessary  due  to  the  uncertain  utilization  of  specific  deferred  tax  assets,  primarily  net  operating  loss 
carryforwards,  with  $21.2  million  in  U.S.  and  $10.6  million  in  Canada;  $21.8  million  of  the  valuation  allowance  is 
related to Aquila. The net change in the Company’s valuation allowance was a decrease of $3.5 million for the year 
ended  December  31,  2023.  The  decrease  in  valuation  allowance  is  primarily  explained  by  expiration  of  foreign  tax 
credits and the write-off of net operating losses now expected to expire unutilized under 382 on a tax-effected basis as 
discussed above. 

At December 31, 2023, the Company has available U.S. federal loss carryforwards of $76.8 million, of which 
$56.2  million  have  no  expiration  date,  and  $20.6  million  that  expire  at  various  dates  between  2027  and  2037;  U.S. 
Foreign  Tax  Credits of $2.0 million  that  expire  at various  dates between  2024  and  2026;  state  of  Colorado  tax  loss 
carryforwards of $53.0 million, of which $29.8 million expire at various dates between 2024 and 2037 and $23.1 million 
that have no expiration; available state of Michigan tax loss carryforwards of $16.8 million expiring at various dates 
between  2024  and  2033;  Wisconsin  tax  loss  carryforwards  of  $4.0  million  expiring  in  2042;  and  Canadian  tax  loss 
carryforwards of $23.0 million that expire between 2026 and 2043. 

Mexico Mining Taxation 

Mining entities in Mexico are subject to two mining duties, in addition to the 30% Mexico corporate income tax: 
(i) a “special” mining duty of 7.5% of taxable income as defined under Mexican tax law (also referred to as “mining 
royalty tax”) on extraction activities performed by concession holders, and (ii) the “extraordinary” mining duty of 0.5% 
on gross revenue from the sale of gold, silver, and platinum. The mining royalty tax is generally applicable to earnings 
before income tax, depreciation, depletion, amortization, and interest. In calculating the mining royalty tax, there are no 
deductions  related  to  depreciable  costs  from  operational  fixed  assets,  but  prospecting  and  exploration  expenses  are 
amortized at 10% rate in a straight line. Both duties are tax deductible for income tax purposes. As a result, our effective 
tax rate applicable to the Company’s Mexican operations is substantially higher than Mexico’s statutory rate. 

The Company periodically transfers funds from its Mexican wholly-owned subsidiary to the U.S. in the form of 
dividends.  Mexico  requires  a  10%  withholding  tax  on  dividends  on  all  post-2013  earnings.  The Company  began 
distributing post-2013 earnings from Mexico in 2018. According to the existing U.S. – Mexico tax treaty, the dividend 
withholding tax between these countries is reduced to 5% if certain requirements are met. The Company determined that 
it had met such requirements and paid a 5% withholding tax on dividends received from Mexico, and as a result, paid 
$0.1 million and $1.3 million for years ending December 31, 2023 and 2022, respectively.  

Other Tax Disclosures 

The Company files U.S. and various state income tax returns, as well as foreign income tax returns in Canada and 
Mexico, with varying statutes of limitations. In general, the statute of limitations is three years in the United States and 
in Canada. However, the Company has net operating loss and tax credit carryforward balances beginning in the tax year 
ended December 31, 2007 for the United States and in the tax year ended December 31, 2006 for Canada. As a result, 
all tax years since 2007 remain open to examination in the United States and all tax years since 2006 remain open to 
examination in Canada. In Mexico, the statute of limitations is generally five years, which currently is 2018 and forward. 
The Company is under audit for the tax year ended December 31, 2015. All other years are closed to inspection outside 
of the standard statute of limitations window in Mexico.

The  U.S.  Treasury  Department  issued  final  regulations  in  July  2020  concerning  global  intangible  low-taxed 
income,  commonly  referred  to  as  GILTI  tax,  which  was  introduced  by  the  Tax  Act  of  2017.  The  GILTI  provisions 
impose a tax on foreign income in excess of a deemed return on tangible assets of foreign corporations. The final tax 
regulations allow income to be excluded from GILTI tax that are subject to an effective tax rate higher than 90% of the 
U.S. tax rate. The Company determined that it is not subject to GILTI tax due to this high tax exception rule. 

In October 2023, the Company received a notification from the Mexican Tax Administration Services (“SAT”) 
with a sanction of 331 million pesos (approximately $19.5 million) as the result of a 2015 tax audit that began in 2021. 
The  2015  tax  audit  performed  by  SAT  encompassed  various  tax  aspects,  including  but  not  limited  to  intercompany 
transactions,  mining  royalty  tax,  and  extraordinary  mining  tax.  Management  is  in  process  of  disputing  this  tax 
notification  and  sent  a  letter  of  protest  to  the  tax  authorities  along  with  providing  all  requested  documentation. 
Management  intends  to  pursue  legal  avenues  of  protest,  including  filing  a  lawsuit  with  the  Mexico  court  system  if 
necessary, to ensure that these adjustments are removed. Management believes the position taken on the 2015 income 
tax return meets the more likely than not threshold and that as of the years ended December 31, 2023 and 2022, the 
Company has no liability for uncertain tax positions. If the Company were to determine there was an unrecognized tax 
benefit,  the  Company  would  recognize  the  liability  and  related  interest  and  penalties  within  income  tax  (benefit) 
provision. 

5. Prepaid Expenses and Other Current Assets

IVA taxes receivable, net is a value added (“IVA”) tax in Mexico assessed on purchases of materials and services 
and sales of products. Likewise, businesses owe IVA taxes as the business sells a product and collects IVA taxes from 
its customers. Businesses are generally entitled to recover the taxes they have paid related to purchases of materials and 
services, either as a refund or credit to IVA tax payable. Amounts recorded as IVA taxes in the consolidated financial 
statements represent the net estimated IVA tax receivable or payable, since there is a legal right of offset of IVA taxes. 
As of December 31, 2023 and 2022, this resulted in an asset balance of $0.4 million and $0.8 million, respectively, 
which is included in other current assets above.

On September 22, 2022, the Company invested C$2.4 million (or $1.7 million) in the common shares of 
Maritime Resources Corp. The 47 million shares purchased represented 9.9% of the issued and outstanding shares of 
Maritime at the time of purchase. As of both December 31, 2023, and December 31, 2022, the fair value of this 
investment was $1.6 million. 

On December 28, 2022, Gold Resource Corporation received 12.25 million common shares of Green Light Metals 
as a settlement for a promissory note receivable acquired with the Aquila acquisition. This represented approximately 
28.5% ownership in Green Light Metals at the time. As of December 31, 2022, the fair value of this equity investment 
was $3.6 million. The contract included a top-up provision that would result in additional common shares being issued 
to the Company if any Green Light Metals financing was raised at less than C$0.40 per share before March 31, 2023. 
After this settlement and before March 31, 2023, additional financing was raised by Green Light Metals at C$0.40 per 
share. Therefore, the top-up provision was not triggered, and no additional shares were received. As of December 31, 
2023, and December 31, 2022, the fair value of this equity investment was $3.7 million and $3.6 million, respectively.

Under Mexican law, employees are entitled to receive statutory profit sharing (Participacion a los Trabajadores 
de las Utilidades or “PTU”) payments. The required cash payment to employees in the aggregate is equal to 10% of their 
employer’s profit subject to PTU, which differs from profit determined under U.S. GAAP. 

In 2023, $0.1 million for PTU was recorded in current liabilities and production costs, as well as $1.2 million for 
statutory employee severance benefits recorded in other long-term liabilities and other expenses. In 2022, $2.2 million

Periodic interest expense incurred based on an implied interest rate. The implied interest rate is determined based 
on  the  timing  and  probability  of  future  production  and  a  6%  discount  rate.  Interest  expense  is  recorded  to  the 
Consolidated Statements of Operations and the gold and silver stream agreement liability on the Consolidated Balance 
Sheet. 

The  stream  agreements  contain  customary  provisions  regarding  default  and  security.  In  the  event  that  our 
subsidiary defaults under the stream agreements, including by failing to achieve commercial production by an agreed 
upon date, it may be required to repay the deposit plus accumulated interest at a rate agreed with Osisko. If the Company 
fails to do so, Osisko may elect to enforce its remedies as a secured party and take possession of the assets that comprise 
the Back Forty Project. 

Gold Streaming Agreement 

In November 2017, Aquila entered into a stream agreement with Osisko Bermuda Limited (“OBL”), a wholly-
owned  subsidiary  of  Osisko  Gold  Royalties  Ltd  (TSX  &  NYSE:  OR),  pursuant  to  which  OBL  agreed  to  commit 
approximately  $55  million  to  Aquila  through  a  gold  stream  purchase  agreement.  In  June  2020,  Aquila  amended  its 
agreement with Osisko, reducing the total committed amount to $50 million, as well as adjusting certain milestone dates 
under the gold stream to align with the current project development timeline. Aquila had received a total of $20 million 
of the committed funds at the time of the Gold Resource Corporation acquisition. Remaining deposits from OBL are $5 
million upon receipt of permits required for the development and operation of the Back Forty Project and $25 million 
upon  the  first  drawdown  of  an  appropriate  project  debt  finance  facility.  OBL  has  been  provided  a  general  security 
agreement over the Back Forty Project, which consists of the subsidiaries of Gold Resource Acquisition Sub. Inc., a 
100% owned subsidiary of Gold Resource Corporation. The initial term of the agreement is for 40 years, automatically 
renewable for successive ten-year periods. The agreement is subject to certain operating and financial covenants, which 
are in good standing as of December 31, 2023. Subsequent to year end, the Company secured an amendment to the 
stream agreement that deferred the required completion of certain operational milestones related to permitting from 2024 
to 2026. 

The  $20  million  received  from  OBL  through  December  31,  2023  is  shown  as  a  long-term  liability  on  the 
Consolidated Balance Sheet, along with an implied interest. The implied interest rate is applied on the OBL advance 
payments and calculated on the total expected life-of-mine production to be deliverable using an estimated gold price 
and a discount rate of 6%. As the remaining $30 million deposit is subject to the completion of specific milestones and 
the satisfaction of certain other conditions, this amount is not reflected on the Consolidated Balance Sheet.

Per the terms of the gold stream agreement, OBL will purchase 18.5% of the refined gold from Back Forty (the 
“Threshold Stream Percentage”) until the Company has delivered 105,000 ounces of gold (the “Production Threshold”). 
Upon satisfaction of the Production Threshold, the Threshold Stream Percentage will be reduced to 9.25% of the refined 
gold (the “Tail Stream”). In exchange for the refined gold delivered under the Stream Agreement, OBL will pay the 
Company ongoing payments equal to 30% of the spot price of gold on the day of delivery, subject to a maximum payment 
of $600 per ounce. Where the market price of gold is greater than the price paid, the difference realized from the sale of 
the  gold  will  be  applied  against  the  deposit  received  from  Osisko.  Please  see  Item  8.  Financial  Statements  and 
Supplementary Data—Note 11. Commitments and Contingencies for additional information. 

Silver Stream Agreement 

Through a series of contracts, Aquila executed a silver stream agreement with OBL to purchase 85% of the silver 
produced and sold at the Back Forty Project. A total of $17.2 million has been advanced under the agreement as of 
December 31, 2023. There are no future deposits remaining under the agreement. The initial term of the agreement is 
for 40 years, automatically renewable for successive ten-year periods. The agreement is subject to certain operating and 
financial covenants, which are in good standing as of December 31, 2023. Subsequent to year end, the Company secured 
an amendment to the stream agreement that deferred the required completion of certain operational milestones related 
to permitting from 2024 to 2026. 

Per the terms of the silver stream agreement, OBL will purchase 85% of the silver produced from the Back Forty 
Project at a fixed price of $4 per ounce of silver. Where the market price of silver is greater than $4 per ounce, the 
difference realized from the sale of the silver will be applied against the deposit received from Osisko. 

The  $17.2  million  received  from  OBL  through  December  31,  2023  is  shown  as  a  long-term  liability  on  the 
Consolidated  Balance  Sheet  and  includes  an  implied  interest  rate.  The  implied  interest  rate  is  applied  on  the  OBL 
advance payments  and  calculated on  the  total  expected  life-of-mine  production  to be deliverable using  an  estimated 
silver  price  and  a  discount  rate  of  6%.  Please  see  Item  8.  Financial  Statements  and  Supplementary  Data—Note  11.

In 2022, the Company updated its closure plan study, which resulted in a $6.4 million increase in the estimated liability and ARO asset. This 
increase is a result of formalizing a tailings storage facility closure plan, the addition of the dry stack facility and the filtration plant, and the 
increase of inflation in Mexico. In 2023, the Company updated its closure plan study to include current disturbances, which resulted in a $1.2 
million decrease in the estimated liability and ARO asset.

(2)  As of December 31, 2022, the Company reported the liability of $0.4 million to remediate exploration drill holes at the Back Forty Project in 
Michigan, USA in other non-current liabilities. As of March 31, 2023, this liability of $0.4 million was reclassified to non-current reclamation 
and remediation liabilities. 

The Company’s undiscounted reclamation liabilities of $2.2 million and $1.9 million as of December 31, 2023 
and  2022,  respectively,  are  related  to  DDGM  in  Mexico.  These  represent  reclamation  liabilities  that  were  expensed 
through 2013 before proven and probable Mineral Reserves were established and the Company was considered to be a 
development stage entity; therefore, most of the costs, including asset retirement costs, were not allowed to be capitalized 
as part of our property, plant, and mine development. 

 The Company’s asset retirement obligations reflect the additions to the asset for reclamation and remediation 
costs in property, plant & mine development, post 2013 development stage status, which were discounted using a credit 
adjusted risk-free rate of 8%. As of December 31, 2023 and 2022, the Company’s asset retirement obligation related to 
the Don David Gold Mine in Mexico was $9.6 million and $8.4 million, respectively. 

11. Commitments and Contingencies 

As  of  December  31,  2023  and  2022,  the  Company  had  equipment  purchase  commitments  aggregating 

approximately $0.8 million and $1.2 million, respectively. 

Contingent Consideration 

With the Aquila acquisition, the Company assumed a contingent consideration. On December 30, 2013, Aquila’s 
shareholders approved the acquisition of 100% of the shares of HudBay Michigan Inc. (“HMI”), a subsidiary of HudBay 
Minerals  Inc.  (“HudBay”),  effectively  giving  Aquila  100%  ownership  in  the  Back  Forty  Project  (the  “HMI 
Acquisition”).  Pursuant  to  the  HMI  Acquisition,  HudBay’s  51%  interest  in  the  Back  Forty  Project  was  acquired  in 
consideration for the issuance of common shares of Aquila, future milestone payments tied to the development of the 
Back  Forty  Project  and  a  1%  net  smelter  return  royalty  on  production  from  certain  land  parcels  in  the  project.  The 
issuance of shares and 1% net smelter obligations were settled before the Company acquired Aquila. 

The contingent consideration is composed of the following:  

The value of future installments is based on C$9 million tied to the development of the Back Forty project as 

follows: 

a.  C$3 million payable on completion of any form of financing for purposes including the commencement of 
construction of Back Forty, up to 50% of the C$3 million can be paid, at the Company’s option in Gold 
Resource Corporation shares with the balance payable in cash; 

b.  C$2 million payable in cash 90 days after the commencement of commercial production; 
c.  C$2 million payable in cash 270 days after the commencement of commercial production, and;  
d.  C$2 million payable in cash 450 days after the commencement of commercial production. 

Initially, the company intended to pay the first C$3 million in 2023 to prevent HudBay’s 51% buy-back option 
in the Back Forty Project. Management later decided that it was more likely than not that HudBay would not exercise 
its  buy-back  option,  and  consequently,  this  amount  was  not  paid.  Additionally,  since  financing  of  the  project  is  not 
expected in 2024, this liability was moved to long-term. As of the end of January 2024, by the contractual deadline, 
HudBay did not exercise its buy-back option, and thus, it is forfeited.  

The total value of the contingent consideration at December 31, 2023 and 2022 was $3.5 million and $4.4 million, 
respectively. The contingent consideration is adjusted for the time value of money and the likelihood of the milestone 
payments. Any future changes in the value of the contingent consideration is recognized in other expense, net, in the 
Consolidated Statements of Operations.

The Company has certain other contingencies resulting from litigation, claims, and other commitments and is 
subject to a variety of environmental and safety laws and regulations incident to the ordinary course of business. The 
Company currently has no basis to conclude that any or all of such contingencies will materially affect its financial 
position, results of operations, or cash flows. However, in the future, there may be changes to these contingencies, or 
additional contingencies may occur, any of which might result in an accrual or a change in current accruals recorded by 
the Company, and there can be no assurance that their ultimate disposition will not have a material adverse effect on the 
Company’s financial position, results of operations or cash flow. 

With the acquisition of Aquila Resources Inc. on December 10, 2021, the Company assumed substantial liabilities 
that  relate  to  the  gold  and  silver  stream  agreements  with  Osisko  Bermuda  Limited.  Under  the  agreements,  Osisko 
deposited a total of $37.2 million upfront in exchange for a portion of the future gold and silver production from the 
Back Forty Project. The stream agreements contain customary provisions regarding default and security. In the event 
that our subsidiary defaults under the stream agreements, including failing to achieve commercial production at a future 
date, it may be required to repay the deposit plus accumulated interest at a rate agreed with Osisko. If it fails to do so, 
Osisko may be entitled to enforce its remedies as a secured party and take possession of the assets that comprise the 
Back Forty Project. 

12. Shareholders’ Equity  

On  February  13,  2023,  the  Company  announced  the  suspension  of  future  quarterly  dividends  to  protect  our 
balance  sheet  and  to  focus  capital  resources  on  exploration  and  growth  opportunities.  Therefore,  in  the  year  ended 
December 31, 2023, the Company neither declared nor paid dividends. The Company declared and paid dividends of 
$3.5 million, or $0.04 per share, for the year ended December 31, 2022. 

The Company’s At-The-Market Offering Agreement with H.C. Wainwright & Co., LLC (the “Agent”), which 
was  entered  into  in  November  2019  (the  “ATM  Agreement”),  pursuant  to  which  the  Agent  agreed  to  act  as  the 
Company’s sales agent with respect to the offer and sale from time to time of the Company’s common stock having an 
aggregate gross sales price of up to $75.0 million, was renewed in June 2023. During the year ended December 31, 2023, 
an  aggregate  of  195,872  shares  of  the  Company’s  common  stock  were  sold  through  the  ATM  Agreement,  for  net 
proceeds to the Company, after deducting the Agent’s commissions and other expenses, of $0.1 million.

Embedded Derivatives 

Concentrate Sales 

Concentrate  sales  contracts  contain  embedded  derivatives  due  to  the  provisional  pricing  terms  for  shipments 
pending final settlement. At the end of each reporting period, the Company records an adjustment to accounts receivable 
and  revenue  to  reflect  the  mark-to-market  adjustments  for  outstanding  provisional  invoices  based  on  forward  metal 
prices. Please  see Item  8.  Financial  Statements  and  Supplementary  Data—Note  19.  Fair  Value  Measurement for 
additional information. 

The  following  table  summarizes  the  Company’s  unsettled  sales  contracts  at  December 31,  2023,  with  the

Derivative instruments that are not designated as hedging instruments are required to be recorded on the balance 
sheet at fair value. Changes in fair value impact the Company’s earnings through mark-to-market adjustments until the 
physical commodity is delivered or the financial instrument is settled. As of December 31, 2022, the hedge program 
concluded,  but  the  Company  may  utilize  similar  programs  in  the  future  to  manage near-term  exposure  to  cash  flow 
variability from metal prices. 

Effective May 18, 2021, GRC entered into a Trading Agreement with Auramet International LLC that governs 
nonexchange traded, over-the-counter, spot, forward, and option transactions on both a deliverable and non-deliverable 
basis involving various metals and currencies, and these contracts are not designated as hedging instruments. Due to the 
conclusion of the current program, in 2023, the Company had neither realized nor unrealized gains or losses, compared 
to a realized loss of $2.0 million and an unrealized gain of $1.8 million in 2022. 

The Company manages credit risk by selecting counterparties that it believes to be financially strong, by entering 
into netting arrangements with counterparties, and by requiring other credit risk mitigants, as appropriate. The Company 
actively  evaluates  the  creditworthiness  of  its  counterparties,  assigns  appropriate  credit  limits,  and  monitors  credit 
exposures against those assigned limits. 

14. Employee Benefits 

Effective October 2012, the Company adopted a profit-sharing plan (the “Plan”) which covers all U.S. employees. 
The Plan meets the requirements of a qualified retirement plan pursuant to the provisions of Section 401(k) of the Internal 
Revenue  Code.  The  Plan  also  provides  eligible  employees  the  opportunity  to  make  tax  deferred  contributions  to  a 
retirement trust account up to 90% of their qualified wages, subject to the IRS annual maximums. 

On April 23, 2021, a decree that reforms labor outsourcing in Mexico was published in the Federation’s Official 
Gazette. This decree amended the outsourcing provisions, whereby operating companies can no longer source their labor 
resources used to carry out the core business functions from service entities or third-party providers. Under Mexican

subject to PTU, which differs from profit determined under U.S. GAAP. Please see Item 8. Financial Statements and 
Supplementary Data—Note 8. Accrued Expenses and Other Liabilities for additional information. 

15. Stock-Based Compensation 

The  Company’s  compensation  program  comprises  three  main  elements:  base  salary,  an  annual  short-term 
incentive plan (“STIP”) cash award, and long-term equity-based incentive compensation (“LTIP”) in the form of stock 
options, restricted stock units (“RSUs”), performance stock units (“PSUs”), and deferred stock units (“DSUs”). 

The Gold Resource Corporation 2016 Equity Incentive Plan (the “Incentive Plan”) allows for the issuance of up 
to 5 million shares of common stock in the form of incentive and non-qualified stock options, stock appreciation rights, 
RSUs,  stock  grants,  stock  units,  performance  shares,  PSUs,  and  performance  cash.  Effective  January  1,  2021,  the 
Company’s Board of Directors, on the recommendation of the Compensation Committee, implemented a program to 
issue DSUs, which are qualifying instruments under the terms of the Company’s Incentive Plan, to eligible directors. 
Additionally, pursuant to the terms of the Incentive Plan, any award outstanding under the prior plan that is terminated, 
expired, forfeited, or canceled for any reason, will be available for grant under the Incentive Plan. 

The Company’s STIP provides for an annual cash bonus payable upon achievement of specified performance 
metrics for its management team. As of December 31, 2023, we accrued $0.8 million payable in cash related to the STIP 
program. As of December 31, 2022, we accrued $1.0 million related to the program. 

Stock-Based Compensation Expense 

Stock-based compensation expense for stock options, RSUs, PSUs, and DSUs is as follows:

The  estimated  unrecognized  stock-based  compensation  expense  from  unvested  options  and  RSUs,  as  of 
December 31, 2023, was nil and $0.7 million, respectively, and is expected to be recognized over the weighted average 
remaining periods of nil and 1.93 year, respectively. As DSUs are vested immediately at grant, the full amount of fair 
value is recognized as expense at the time of grant. In addition, a mark-to-market adjustment due to fluctuation of share 
price is recognized at the end of each period related to the DSUs. The fair value of the PSUs is recognized over their 
vesting period of three years, and similarly to the DSUs, a mark-to-market adjustment due to fluctuation of the share 
price, as well as due to changes in the performance, is recognized at the end of each period related to the proportionate 
number of units based on passage of time.

Starting in 2022, the Company’s Board of Directors approved granting performance share units to the Company’s 
management team. PSUs cliff vest in three years based on the relative total shareholder return of a predetermined peer 
group and are expected to be settled in cash. These awards contain a cash settlement feature and are therefore classified 
as  liability  and  are  marked  to  fair  value  each  reporting  period  based  on  the  relative  total  shareholder  return  of  a 
predetermined peer group and the Company’s stock price. As of December 31, 2023 and 2022, the Company has liability 
of $0.2 million and $0.3 million, respectively, related to PSUs. As of December 31, 2023, of the $0.2 million liability, 
$0.1 million is short-term and expected to be paid out in 2024 according to the terms of the grant agreements. 

PSUs of 534,890 and 695,041, respectively, were granted during the years ended December 31, 2023 and 2022, 
with  weighted-average  fair  value  of  $0.90  and  $1.99  per  unit,  respectively.  The  grant  date  fair  value  of  PSUs  is

Effective  January  1,  2021,  the  Company’s  Board  of  Directors,  on  the  recommendation  of  the  Compensation 
Committee, implemented a program to issue deferred stock units to members of the Company’s Board of Directors. 
Additionally, members of the Board may elect, at the beginning of each year, that a portion of their board fees be paid 
in DSUs rather than in cash. DSUs are qualifying instruments under the terms of the Company’s Incentive Plan, and 
therefore, do not require additional shareholder approval. The vesting and settlement terms of the DSUs are determined 
by the Compensation Committee at the time the DSUs are awarded.  

DSUs are vested immediately at grant and are redeemable in cash or shares—at the discretion of the Company—
at the earlier of 10 years or upon the eligible directors’ termination and expected to be paid in cash. Termination is 
deemed to occur on the earliest of (1) the date of voluntary resignation or retirement of the director from the Board; (2) 
the  date  of  death  of  the  director;  or  (3)  the  date  of  removal  of  the  director  from  the  Board  whether  by  shareholder 
resolution, failure to achieve re-election, or otherwise; and on which date the director is not a director or employee of 
the Company or any of its affiliates. These awards contain a cash settlement feature and are therefore classified as a 
liability and are marked to fair value each reporting period. As of December 31, 2023 and 2022, the Company has $0.2 
million and $0.6 million, respectively, of other non-current liability related to the DSUs, based on the fair value of the 
Company’s stock price. 

DSUs of 278,663 and 214,357 were granted to the Board of Directors during the years ended December 31, 2023 
and 2022, respectively. Additionally, DSUs of 108,011 and 14,382 were granted to the Board of Directors in lieu of 
board fees at their request during the years ended December 31, 2023 and 2022, respectively. DSUs of 212,407 and nil, 
respectively,  were  granted  in  lieu  of  executive  bonuses  during  the  years  ended  December  31,  2023  and  2022.  The 
weighted-average grant date fair value per share of DSUs granted during the years ended December 31, 2023 and 2022 
was $0.83 and $2.93, respectively. The grant date fair value of DSUs is determined by the 20-day volume weighted 
average price of the Company’s common shares at grant date. During the year ended December 31, 2022, no DSUs were 
redeemed  or  forfeited,  and  373,489  and  nil  DSUs,  respectively,  were  redeemed  and  forfeited  during  the  year  ended 
December 31, 2023.

nonexchange traded, over-the-counter, spot, forward and option transactions on both a deliverable and non-deliverable 
basis involving various metals and currencies. In 2022, the Company had a realized loss of $2.0 million and an unrealized 
gain of $1.8 million related to the program. As of December 31, 2022, the current program concluded; therefore, in 
2023, the Company had neither realized nor unrealized gains or losses related to the program. However, the Company 
may enter into similar zinc zero cost collar call and put options in the future. Please see Item 8. Financial Statements

18. Net Loss per Common Share 

Basic loss per common share is calculated based on the weighted average number of shares of common stock 
outstanding for the period. Diluted Loss per common share is calculated based on the assumption that stock options 
outstanding, which have an exercise price less than the average market price of the Company’s common stock during 
the period, would have been exercised on the later of the beginning of the period or the date granted and that the funds 
obtained from the exercise were used to purchase common shares at the average market price during the period. All of 
the Company’s restricted stock units are considered to be dilutive. 

The  effect  of  the  Company’s  dilutive  securities  is  calculated using  the  treasury  stock method,  and  only  those 
instruments that result in a reduction in net income per common share are included in the calculation. Options to purchase 
0.8 million shares of common stock at weighted average exercise prices of $2.99 were outstanding as of December 31, 
2023 but had no dilutive effect due to the net loss. Options to purchase 1.5 million shares of common stock at weighted 
average exercise prices of $2.90 were outstanding as of December 31, 2022 but had no dilutive effect due to the net loss.

Fair value accounting establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to 
measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical 
assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The 
three levels of the fair value hierarchy are described below:  

Level 1  Unadjusted  quoted  prices  in  active  markets  that  are  accessible  at  the  measurement  date  for  identical, 

unrestricted assets or liabilities;  

Level 2  Quoted  prices  in  markets  that  are  not  active,  or  inputs  that  are  observable,  either  directly  or  indirectly,  for 

substantially the full term of the asset or liability; and  

Level 3  Prices or valuation techniques that require inputs that are both significant to the fair value measurement and 

unobservable (supported by little or no market activity.)  

As required by accounting guidance, assets and liabilities are classified in their entirety based on the lowest level 
of input that is significant to the fair value measurement. These assets and liabilities are remeasured for each reporting 
period. The following tables set forth certain of the Company’s assets and liabilities measured at fair value by level 
within the fair value hierarchy as of December 31, 2023 and 2022:

The following methods and assumptions were used to estimate the fair value of each class of financial instrument: 

Cash and cash equivalents: Cash and cash equivalents consist primarily of cash deposits and are valued at cost, 

which approximates fair value.  

Accounts  receivable,  net:  Accounts  receivable,  net  include  amounts  due  to  the  Company  for  deliveries  of 
concentrates and doré sold to customers. Concentrate sales contracts provide for provisional pricing as specified in such 
contracts. These sales contain an embedded derivative related to the provisional pricing mechanism which is bifurcated 
and accounted for as a derivative. At the end of each reporting period, the Company records an adjustment to sales to 
reflect  the  mark-to-market  of  outstanding  provisional  invoices  based  on  the  forward  price  curve.  Because  these

provisionally priced sales have not yet settled as of the reporting date, the mark-to-market adjustment related to these 
invoices is included in accounts receivable as of each reporting date. At December 31, 2023 and 2022, the Company 
had  an  unrealized  gain  of  $0.3  million  and  $0.6  million,  respectively,  included  in  its  accounts  receivable  on  the 
accompanying  Consolidated  Balance  Sheets  related  to  mark-to-market  adjustments.  Please  see Item  8.  Financial 
Statements and Supplementary Data—Note 13. Derivatives for additional information. 

Investment in equity securities—Maritime: On September 22, 2022, Gold Resource Corporation invested C$2.4 
million (or $1.7 million) in the common shares of Maritime Resources Corp., ticker symbol MAE.V on TSX-V, in a 
private placement. The 47 million shares purchased represent less than 10% of the issued and outstanding shares of 
Maritime. As of both December 31, 2023 and 2022, the share price of Maritime was C$0.045. 

Investment  in  equity  securities—Green  Light  Metals:  Upon  maturity  on  December  28,  2022,  the  Company 
received 12,250,000 private shares of Green Light Metals, which settled the promissory note receivable from Green 
Light Metals. The shares received represented approximately 28.5% ownership. Management chose to account for this 
investment using the fair value option; therefore, these securities are carried at fair value. As of December 31, 2023, the 
value of this equity investment was C$4.9 million (or $3.7 million). The value of the issued shares was determined to 
be  C$0.40  per  share,  which  was  based  on  the  significant  unobservable  input  of  recent  Green  Light  Metals  equity 
transactions. Through December 31, 2023, there have been no gains or losses on the value of the shares the Company 
received, other than some foreign exchange gain. 

Gains and losses related to changes in the fair value of these financial instruments were included in the Company’s

As  of  December  31,  2023,  the  Company  has  organized  its  operations  into  three  geographic  regions.  The 
geographic regions include Oaxaca, Mexico, Michigan, U.S.A. and Corporate and Other. Oaxaca, Mexico represents 
the  Company’s  only  production  stage  property.  Michigan,  U.S.A.  is  an  advanced  exploration  stage  property. 
Intercompany revenue and expense amounts have been eliminated within each segment in order to report the net income 
(loss)  on  the  basis  that  management  uses  internally  for  evaluating  segment  performance.  The  Company’s  business 
activities that are not considered production stage or advanced exploration stage properties are included in Corporate 
and Other.

ITEM 9A. 

CONTROLS AND PROCEDURES  

Evaluation of Disclosure Controls and Procedures 

Our disclosure controls and procedures are designed to ensure that information required to be disclosed in the 
reports that we file under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), is recorded, processed, 
summarized,  and  reported  within  the  time  periods  specified  in  the  rules  and  forms  of  the  Securities  and  Exchange 
Commission,  and  that  such  information  is  accumulated  and  communicated  to  our  management,  including  our  Chief 
Executive Officer and Chief Financial Officer, as appropriate, to allow timely decisions regarding required disclosure. 
The  Chief  Executive  Officer and  the  Chief Financial  Officer,  with  assistance  from management, have  evaluated  the 
effectiveness  of  disclosure  controls  and  procedures  as  of  December 31, 2023.  Based  on  that  evaluation,  the  Chief 
Executive  Officer  and  the  Chief  Financial  Officer  have  concluded  that  our  disclosure  controls  and  procedures  were 
effective as of December 31, 2023. 

Management's Report on Internal Control over Financial Reporting  

Management is responsible for establishing and maintaining adequate internal control over financial reporting 
and for the assessment of the effectiveness of internal control over financial reporting as defined in Rules 13a-15(f) and 
15d-15(f) under the Exchange Act. Because of its inherent limitations, any system of internal control over financial 
reporting, no matter how well designed, may not prevent or detect misstatements due to the possibility that a control can 
be circumvented or overridden or that misstatements due to error or fraud may occur that are not detected. Also, because 
of changes in conditions, internal control effectiveness may vary over time. Management assessed the effectiveness of 
the Company’s internal control over financial reporting as of December 31, 2023 based on the framework set forth by 
the  Committee  of  Sponsoring  Organizations  of  the  Treadway  Commission  (“COSO”)  in  Internal  Control-Integrated 
Framework (2013) and concluded that the Company has maintained effective internal control over financial reporting 
as of December 31, 2023 based on the COSO criteria.  

Changes in Internal Control over Financial Reporting 

There have been no changes in our internal control over financial reporting (as defined in Rule 13a-15(f) under 
the Exchange Act) which occurred during the fourth quarter of our year ended December 31, 2023 that have materially 
affected, or are reasonably likely to materially affect, our internal control over financial reporting.
