“EroCopper’s ESG performance and commitment 
to sustainability are focus areas of the Board and 
Management and we look forward to executing on 
the sustainability goals we set in 2020.”

Our balance sheet is the strongest it has been
since the Company’s inception. Record annual
copper production, strong copper and gold
commodity prices and a weak Brazilian Real
relative to the US Dollar contributed to our record
performance in 2020. Amendments made to the
Company’s existing credit
facilities in the first
quarter of 2020 provide financial flexibility as we
advance our organic growth initiatives in the years
to come.

2020 Highlights 

2020 Operational Highlights 

Strong year-end – full-year production guidance achieved, below revised operating cost guidance range 

• 

Increased year-on-year copper production at high-end of Company’s guidance range with 42,814 tonnes 
of copper produced in concentrate.   

•  Approximately  2.3  million  tonnes  of  ore  grading  2.08%  copper  processed  with  average  metallurgical 

recoveries of 90.5%. 

•  C1 cash cost of $0.67 per pound of copper produced, $0.03 cents below the low-end of the Company’s 

revised guidance range of $0.70 to $0.85 per pound of copper produced for 2020. 

•  Full-year  C1  cash  costs  reflect  a  year-on-year  reduction  of  $0.26  per  pound  of  copper  produced  as 

compared to 2019. 

•  Advanced  several  key  capital  programs  in  2020  including  completion  of  the  Company’s  high-intensity 
grinding  (“HIG”)  Mill  installation,  ore-sorting  pilot  plant  program,  and  drilling  and  integration  of  the 
Deepening Extension Project (as defined below) into the Company’s recently announced life-of-mine plan 
update for 2020.  

•  Achieved one-year without a lost-time injury at the Company’s MCSA Mining Complex prior to the end of 

2020, a record in the mine’s 40 plus year operating history. 

•  Total annual gold and silver production at the NX Gold Mine of 36,830 ounces gold and 22,694 ounces 
silver at C1 cash costs of $457 per ounce of gold produced, in-line with the Company’s revised 2020 NX 
Gold guidance, and AISC of $628 per ounce of gold produced. 

2020 Financial Highlights 

Cash  position  and  available  lines  of  credit:  Total  cash  and  cash  equivalents  and  available  lines  of  credit  at 
December 31, 2020 was $62.5 million and $11.6 million compared to $21.5 million and $30.0 million, respectively, 
at the end of 2019. The Company’s working capital improved from a deficit of $4.9 million at the end of 2019 to a 
surplus  of  $35.8  million  at  the  end of 2020,  primarily  as  a  result  of  a  record  $162.8  million  in cash  flow from 
operations for Fiscal 2020, compared with $127.8 million in cash flow from operations for Fiscal 2019. As at the 
end of 2020, the Company had R$60.4 million in available undrawn lines of credit in Brazil. 

Revenue: The Company increased year-on-year revenues from its copper operations at MCSA by 6.0%, totalling 
$260.9 million in 2020 compared to $246.2 million in 2019. The increase in revenue was primarily attributed to an 
increase in realized copper prices. 

Year-on-year increase in gold revenue from the Company’s gold operations at NX Gold was a result of increased 
gold and silver prices and increased production volumes, resulting in an increase in gold revenue of 63.5% to $63.2 
million in 2020 compared to $38.6 million in 2019. 

Mine gross profit: The Company significantly increased year-on-year mine gross profit from its copper operations 
at MCSA totaling $146.4 million in 2020 compared to $105.6 million in 2019. The increase in mine gross profit was 
primarily driven by increased revenues from higher realized copper prices, increased copper concentrate sales, 
lower operating costs over the prior year as a result of higher grades processed, and a weakened BRL against the 
USD. The Company also recognized mine gross profit of $41.8 million in 2020 compared to $11.4 million in 2019 
from its gold operations at NX Gold as a result of higher gold production volumes, higher gold sales, and higher 
realized gold prices.   

Net income: The Company recognized net income attributable to the Company of $51.6 million (net income per 
share, basic, of $0.60) in 2020 compared to $91.9 million (net income per share, basic, of $1.08) in 2019. While 
revenue and mine gross profit increased, net income decreased, primarily driven by increased foreign exchange 
losses  from  the  weakening  of  the  BRL  against  the  USD  and  increased  income  tax  expense,  partially  offset  by 
decreased  costs  associated  with  the  weakened  BRL  in  which  cost  is  incurred.  Additionally,  during  2019,  the 
Company recognized a recovery of $21.6 million in net income related to value added taxes in Brazil due to a 2017 
Brazil  Supreme  Court  ruling  that  concluded  the  relevant  tax  authorities  had  historically  used  an  incorrect 

E R O   C O P P E R  |     2 0 2 0   A N N U A L   R E V I E W     |   1 0  

 
 
 
methodology to determine such taxes, as well as a $28.3 million net deferred tax recovery primarily resulting from 
the recognition of available tax losses and tax credits in MCSA. No such recoveries were recognized during 2020.  

Q4 2020 Highlights 

Proactive mitigation of the potential impacts of the COVID-19 pandemic throughout 2020 

•  The Company continues to have no material disruption to operations, supply chains or sales channels as 
a result of the COVID-19 pandemic. Since the onset of the COVID-19 pandemic in early 2020, the Company 
has continued to take extraordinary measures to mitigate the impact of COVID-19 on its workforce and 
operations. Some of these measures include: 

(i)  eliminating all non-essential travel to and from the Company’s mining operations;  
(ii)  routine  engagement  with  all  suppliers  and  active  stockpiling  of  key  consumables  to  protect 

against any supply chain disruptions; 

(iii) reducing  physical  interaction  throughout  the  organization  as  much  as  possible  by  closing 
administrative offices and moving to a work-from-home format, increasing social distancing by 
limiting the number of employees travelling on provided buses between the Company’s mining 
communities  and mines,  limiting the  number of employees  in the cafeteria  at any  given time, 
cancelling all group meetings, implementing social-distancing for essential line-out meetings and 
encouraging work-from-home and video/telephone conferencing where feasible; 

(iv) establishing COVID-19 committees with senior leadership and local health administrators for the 

regions in which the Company operates;  

(v)  purchasing thousands of COVID-19 testing kits for the Company’s operations, with the donation 
of  a  portion of  these  test kits,  as well  as other  personal  protective  equipment,  to each  of  the 
Company’s local municipalities to facilitate rapid testing throughout each community; and, 
(vi) implementing  wellness  education,  health  screenings,  and  self-isolation  protocols  along  with 

enhanced sanitization throughout the Company’s operations. 

•  The Company continues to closely monitor the COVID-19 pandemic and is engaged in active operational 
and  financial  contingency  planning  to  prudently  manage  the  potential  impact  of  the  pandemic  on  its 
operations. 

Strong operational performance at MCSA Mining Complex and NX Gold Mine during Q4 2020 

•  483,447 tonnes processed grading 2.26% copper producing 10,018 tonnes of copper in concentrate after 

metallurgical recoveries that averaged 91.7% during Q4 2020 at the MCSA Mining Complex. 

•  45,574  tonnes  of  ore  grading  7.72  grams  per  tonne  gold  producing  10,789  ounces  of  gold  and  6,763 
ounces of silver as by-product after metallurgical recoveries that averaged 95.4% during Q4 2020 at the 
NX Gold Mine. 

•  Q4 2020 C1 cash costs of $0.69 per pound of copper produced at the MCSA Mining Complex, C1 cash costs 
of $405 per ounce of gold produced and AISC of $608 per ounce of gold produced at the NX Gold Mine 
(see Non-IFRS Measures). 

•  As  a  result  of  strong  operating  and  financial  performance  throughout  2020,  the  Company  ended  the 
period  with  a  robust  cash  and  cash  equivalents  position  of  $62.5  million,  a  quarter-on-quarter 
improvement of $8.2 million and a $41.0 million improvement since December 31, 2019. 

2020 updated mineral resource, reserve and life-of-mine plans outline significant increases in mineral reserves 
and extension of mine life across the Company’s operations 

•  At the MCSA Mining Complex, significant year-on-year increases in contained copper within the Proven 
and Probable mineral reserves, Measured and Indicated, and Inferred mineral resource categories, were 
outlined with each increasing by 23%, 29% and 62% respectively, inclusive of the newly defined Deepening 
Extension Zone at the same long-term copper price assumption of US$2.75 per pound.  

•  Updated life-of-mine copper production for the MCSA Mining Complex, totalling approximately 480,800 
tonnes of copper at an average C1 cash costs of $0.97 per pound of copper produced, at a US Dollar to 
Brazilian Real foreign exchange rate of 5.00.

•  At the NX Gold Mine, a 78% increase in contained gold within the Probable mineral reserve category was 
outlined, totalling 862,134 tonnes grading 8.83 grams per tonne containing 244,650 ounces of gold. 
•  Updated life-of-mine gold production from the NX Gold Mine totalling approximately 227,000 ounces of 
gold produced over a six-year mine life, at an average annual production rate of approximately 36,000 
ounces of gold (approximately 41,400 ounces over the first four years) at life-of-mine (“LOM”) average C1 
cash costs of US$505 per ounce of gold produced and life-of-mine average AISC of US$720 per ounce (see 
Non-IFRS Measures). 

MCSA exploration programs continue to demonstrate continuity of high-grade mineralization post life-of-mine 
plan update as well as newly discovered PGM occurrences throughout the Curaçá Valley  

• 

•  During  the  period,  the  Company  identified  an  unexpected  new  zone  of  high-grade  “Superpod”  style 
mineralization in the south-central section of the zone that has the potential to meaningfully increase 
copper grades within the Deepening Extension Zone of the Pilar Mine. Results in this area include hole 
FC48155 that intersected 46.5 meters grading 4.96% copper including 36.5 meters grading 6.08% copper 
and  6.0  meters  grading  11.98%  copper.  On  the  same  section,  hole  FC48161  intersected  20.3  meters 
grading 4.76% copper including 9.5 meters grading 7.12% copper providing further evidence of high-grade 
mineralization. 
In addition, a new target zone, interpreted as a potential parallel lens at depth within the Pilar Mine, was 
identified approximately 70 to 120 meters east of the main Deepening Extension Zone. Initially defined 
by hole FC47173 that intersected 7.2 meters grading 3.28% copper including 3.0 meters grading 4.35% 
copper  and  hole  FC5381  that  intersected  6.0 meters  grading  1.07%  copper,  drilled  approximately 300 
meters apart, the zone has been interpreted to extend approximately 600 meters in strike length.  
•  Exploration drilling in the Southern Vermelhos Corridor of the Vermelhos District continued to intercept 
stacked  mineralized  lenses  within  a  modeled  structural  corridor,  extending  over  700  meters  in  strike 
length.  Five  drill  rigs  are  scheduled  to  systematically  drill  this  target  area  during  2021  and  down-hole 
electromagnetic (“EM”) targeting work remains ongoing.  
Initial results from a program designed to evaluate platinum group metal (“PGM”) associations within the 
Curaçá  Valley  were  received  during  the  period.  The  program,  which  commenced  in  early-2020,  has 
resulted  in  the  interpretation  of  three  distinct  styles  of  PGM  mineralization  that  can  be  observed  in 
samples throughout each of the Company’s main operating districts. Occurrences of elevated PGMs have 
now  been  documented  from  near-surface  open  pit  deposits  to  the  deepest  known  extent  of 
mineralization within the Pilar Mine. Results for each style of mineralization are highlighted by: 

• 

(i)  Style 1, high-grade copper-nickel-PGMs (this style of mineralization shows similarities to footwall 
zones described within the Sudbury District, Canada and localized copper-rich mineralized zones 
at  Noril’sk,  Russia),  highlighted  by  previously  announced  Siriema  results:  FSI-40,  9.1  meters 
grading  2.59%  copper,  1.74%  nickel  and  1.61  grams  per  tonne  (“gpt”)  4PGE+Au  including  5.6 
meters  grading  3.37%  copper,  2.59%  nickel  and  2.28gpt  4PGE+Au  (platinum  group  elements 
(“PGEs”) in this context are defined as platinum, palladium, rhodium and ruthenium); 

(ii)  Style  2,  high-grade  PGM 

low-sulphide  content,  reef-style  mineralization  (this  style  of 
mineralization shows similarities described in PGM deposits, such as the Bushveld Complex, South 
Africa  and  some  zones  within  the Marathon  Intrusion,  Canada),  highlighted  by:  hole  FC47139, 
within the Pilar Deepening Extension, 1.0 meter grading 0.76% copper, 0.05% nickel and 4.12gpt 
4PGE+Au; and, 

(iii) Style 3, copper-palladium rich (this style of mineralization shows similarities to zones described 
within  the  Sudbury  District  and  Marathon  Intrusion),  highlighted  by:  FS-E002,  a  near-surface 
sample from beneath the Surubim open pit mine, 27.0 meters grading 2.04% copper, 0.06% nickel 
and  0.33gpt  4PGE+Au  including  6.0  meters  grading  3.03%  copper,  0.13%  nickel  and  0.87gpt 
4PGE+Au. 

•  Based upon these results, a comprehensive review of PGM occurrences, comprising approximately 5,000 
additional samples, is underway to better understand continuity and significance of these initial results.

Exploration  of  the  Santo  Antonio  Vein  at  the  NX  Gold  Mine  continues  to  demonstrate  continuity  of 
mineralization  

•  The Company continued to have success in demonstrating down-plunge continuity and extensions of the 
high-grade mineralization of the Santo Antonio Vein at the NX Gold Mine. The results were highlighted 
during  the  period  by  hole  SA89  that  intersected  2.7  meters  grading  15.38  grams  per  tonne  gold, 
representing the deepest intercept drilled to date by the Company at the Santo Antonio Vein. 

Q4 2020 Financial Report 

•  Cash flow from operations: Q4 2020 cash flow from operations was $38.6 million, an increase of $2.7 

million from $35.9 million in Q4 2019. 

•  Adjusted net income per share (see Non-IFRS Measures): Q4 2020 adjusted net income per share was 
$0.43 and $0.40, on a basic and diluted basis, respectively, compared with Q4 2019 adjusted net income 
per share of $0.47 and $0.44, on a basic and diluted basis, respectively. 

•  Unrealized foreign exchange gains: Q4 2020 financial results were impacted by the strengthening of the 
BRL against the USD in comparison to the end of the third quarter of 2020, mainly through the change in 
the mark-to-market valuation of derivatives used to hedge BRL revenues. During Q4 2020, the Company 
recognized a $27.7 million non-cash valuation gain on its USD/BRL foreign exchange collars.   
-  The  Company  uses  these  structures  to  hedge  Brazilian  Real  measured  revenues.  As  a  result  of  the 
COVID-19  pandemic  and  its  impact  on  macro-economic  interrelationships,  there  was  a  continual 
increase in implied volatility of the BRL versus USD.  

-  Generally accepted accounting standards dictate that the liability be recognized at fair value, which 
requires  management  to  estimate  fair  value  using  a  Black-Scholes  valuation  methodology  and 
assumptions for the foreign exchange rate and volatility.  

-  The  Company  does  not  believe  that  this  impact  on  the  income  statement  reflects  the  underlying 
profitability  of  the  Company  as  it  provides  no  offset  for  the  expected  future  benefits/costs  of  a 
lower/higher BRL/USD exchange rate on operating costs and capital expenditures of the Company’s 
underlying business. These benefits/costs may outweigh the Company’s projected hedge losses/gains 
that may result from these collars. 

•  Credit facilities amendment: Subsequent to the year ended December 31, 2020, the Company’s existing 
US$75  million  term  facility  and  US$75  million  revolving  credit  facility  previously  entered  into  with  a 
syndicate of Canadian financial institutions were amended with a US$150 million senior secured revolving 
credit facility (the “New Revolving Credit Facility”) payable entirely on March 31, 2025.  

Benefits  of  the  amendment  include  a  reduction  of  up  to  25  basis  points  in  the  Company’s  cost  of 
borrowing, depending on consolidated leverage ratio. The New Revolving Credit Facility will bear interest 
on  a  sliding  scale  at  a  rate  of  LIBOR  plus  2.25%  to  4.25%  depending  on  the  Company’s  consolidated 
leverage ratio at the time. Commitment fees for any undrawn portion of the Revolving Credit Facility will 
also be on a sliding scale between 0.56% to 1.06%.  

The  New  Credit  Facility  includes  standard  and  customary  terms  and  conditions  with  respect  to  fees, 
representations, warranties, and financial covenants that remain unchanged from prior amendments.

REVIEW OF OPERATIONS 

Mineração Caraíba S.A. (Vale do Curaçá):  

Q4 2020 was the culmination of a strong operating year for the Company’s MCSA Mining Complex, which despite 
the COVID-19 pandemic, continued to perform well. Quarter-on-quarter declines in tonnes mined, were offset by 
increases in copper grades (2.26% vs. 2.18% copper in Q3 2020) and metallurgical recoveries (91.7% vs. 90.8% in 
Q3  2020).  Improved  metallurgical  recoveries  were  driven,  in  part,  by  the  installation  of  commissioning  of  the 
Company’s new HIG Mill, which was completed at the end of Q3 2020. While feed system work remained ongoing 
during Q4 2020, the Company continues to expect an improvement in metallurgical recoveries in the future as a 
result of the successful implementation to date. 

At  the Pilar  Mine,  356,016  tonnes  of ore were  mined  grading  1.74%  copper  during  Q4  2020  (as  compared  to 
375,296 tonnes of ore mined grading 1.36% copper during Q3 2020). At the Vermelhos Mine, 187,659 tonnes of 
ore were mined grading 3.19% copper (as compared to 227,963 tonnes of ore mined grading 3.76% copper during 
Q3 2020).  In total,  contributions  from  both mines  during  the  period  resulted  in  543,675 tonnes  of  ore  mined 
grading 2.24% copper. For the full-year 2020, a total of 2,345,002 tonnes of ore grading 2.10% copper was mined. 
During Q4 2020, 483,447 tonnes of ore grading 2.26% copper was processed, producing 10,018 tonnes of copper 
after average metallurgical recoveries of 91.7%. For the full-year of 2020, a total of 2,271,625 tonnes of ore grading 
2.08% copper was processed, producing 42,814 tonnes of copper after average metallurgical recoveries of 90.5%. 

C1 cash costs per pound of copper produced averaged $0.69 (see Non-IFRS Measures) during Q4 2020, reflecting 
strong operational performance at the Company’s MCSA operations, continued weakness of the BRL versus the 
US dollar and strength in the price of gold and silver produced as by-products. Decreased copper production, a 
strengthening of the BRL vs. the US dollar relative to the prior period, and scheduled mill maintenance at year-
end contributed to a $0.06 increase in C1 cash costs per pound of copper produced as compared to Q3 2020. Full-
year 2020 C1 cash costs averaged $0.67 per pound of copper produced – a $0.26 decrease as compared to 2019.  

During Q4 2020, the Company announced updated mineral resources, mineral reserves and an updated LOM plans 
for the MCSA Mining Complex encompassing the exploration drill programs conducted during the year. Within 
the MCSA Mining Complex LOM production plan, for the 2020 update, the Company included production, capital 
and operating cost projections based upon the mineral reserves derived from the Measured and Indicated mineral 
resources from within the Deepening Extension Zone of the Pilar Mine (the “Deepening Extension Project”), which 
was  a  core  objective  of  the  Company  during  the  year.  In  addition,  the  Company  included  an  independent 
preliminary  economic  assessment  based  upon  the  Inferred mineral resources within  the  Deepening  Extension 
Zone of the  Pilar Mine  (the  “Deepening Inferred  Project”),  that  shows the expected synergies associated with 
utilizing the infrastructure that will be built in support of the Deepening Extension Project. With the inclusion of

the Deepening Extension Project at the Pilar Mine, a significant increase in production from the current 1.2 million 
tonnes per annum of ore mined to approximately 2.2 million tonnes of ore mined is planned. The expansion of 
the Pilar  Mine  will be  supported by the  installation of a new  4.5 meter diameter  external shaft, scheduled to 
commence construction in Q3 2021, that will not only support the planned increases in copper production at the 
Pilar Mine, as outlined in the LOM, but has also been designed to support the potential for longer term copper 
production  increases  from  both  the  Deepening  Inferred  Project  and  as  additional  mineralization  is  defined.  In 
keeping with the Company’s return on invested capital focus, the expansion of the mine and development of the 
infrastructure in support of the Deepening Extension Project is expected to be delivered at a low capital-intensity 
ratio of approximately US$1,677 per tonne of incremental copper production delivered. 

In addition, integration of ore sorting into the Company’s LOM plan for the Vermelhos District open pit deposits 
of N8/N9 and Siriema is expected to contribute to improved mill head-grades and maintaining first-quartile C1 
cash costs over the LOM. In total, approximately 20 million tonnes of ore grading 0.56% are expected to be mined 
and sorted, producing a sorted mill-feed of approximately 8.9 million tonnes of ore grading 1.18% copper. As a 
result of the integration of ore sorting approximately 11.0 million tonnes of waste material will be prevented from 
being transported and processed at the Company’s mill over the LOM. In  addition to the associated economic 
benefits, this reduction is expected to substantially reduce consumption of fresh-water, diesel and electricity as 
well as reduce flotation tailings generated per tonne of copper produced, further advancing the Company’s long-
term environmental and sustainability commitments within the Curaçá Valley. 

Please refer to the Company’s press releases dated November 30, 2020 for complete information related to the 
LOM plan for the MCSA Mining Complex.  

On  exploration,  the  Company’s  organic  growth  strategy  remains  supported  by  one  of  the  world’s  largest 
exploration programs, which continued following the release of the latest LOM plan update. During Q4 2020, the 
Company continued to focus its exploration efforts on three primary exploration areas within the Curaçá Valley 
(please  refer  to  the  Company’s  press  release  dated  December  15,  2020  for  complete  results).  These  areas 
included: 

(i) 

continued drilling of the Pilar Mine Deepening Extension Zone in an effort to further demonstrate high-
grade continuity outside the previously known limits of mineralization within the mine;  

(ii)  extensional drilling of the Southern Vermelhos  Corridor, a target zone extending over 700 meters in 
strike length between Siriema and the Vermelhos Mine to further evaluate continuity of mineralization 
and the potential for multiple “stacked” high-grade lenses; and, 
(iii)  a strategic review of PGM occurrences throughout the Curaçá Valley. 

In the Pilar Mine, exploration activities during the period sought to commence a new phase of drilling following 
the release of the Company’s updated LOM to further demonstrate continuity of mineralization as well as upgrade 
the  inferred mineral  resources  that  comprise  the  Deepening  Inferred  Project.  A  surface  drill  program  utilizing 
directional drilling technology to evaluate the mineralized potential of the Deepening Extension Zone north of 
section 57 continued as planned during the period and this program will continue into 2021. The known limits of 
mineralization within the Deepening Extension Zone, which remain open, extend over approximately 900 meters 
in strike length, over a total depth of approximately 525 meters and over average thicknesses ranging from 10 to 
20 meters with localized thickening throughout the zone. Within the total strike length, a higher-grade continuous 
zone of approximately 400 to 500 meters in strike length continues to be supported in the central and northern 
segments of the target area, and a new zone of high-grade mineralization is emerging at depth in the south-central 
segment of this area. The zone remains open to the north and to depth. Five underground exploration drill rigs 
will continue to systematically drill the defined exploration target area within the Deepening Extension Zone in 
2021.  

Also within the Pilar Mine, a new zone of parallel mineralization at depth, and a new target zone, was identified 
during the period, located approximately 70 to 120 meters east of the main Deepening Extension Zone. Results

during the period are highlighted by hole FC47173 that intersected 7.2 meters grading 3.28% copper including 3.0 
meters grading 4.35% copper and hole FC5381 that intersected 6.0 meters grading 1.07% copper. The intercept 
in hole FC47173 is approximately 300 meters south of the intercept in hole FC5381, approximately 80 meters to 
the east of the main Deepening Extension Zone and approximately 400 meters south of previously drilled holes 
that also intersected this target area. The potential for a new, parallel structure extends over a north-south strike 
length of approximately 600 meters. 

In the Vermelhos District, approximately 80 kilometers to the north of the Caraíba Mill complex, which includes 
the  high-grade  operating  Vermelhos  Mine,  exploration  activities  during  the  period  focused  on  two  primary 
objectives: (i) testing continuity of high-grade copper mineralization within the Southern Vermelhos Corridor and 
(ii)  conducting  down-hole  EM  surveys  to  identify  high-grade  exploration  targets.  Preliminary  results  of  this 
program, which remains ongoing, continues to demonstrate the presence of multiple stacked mineralized lenses, 
including high-grade mineralization within the corridor. Five drill rigs are expected to be operational within the 
Southern Vermelhos Corridor during 2021 focused on systematic drill testing. The program has been designed on 
50 meter drill spacing. Initially, the focus will be the northern section of the Southern Vermelhos Corridor given 
its proximity to the existing mine infrastructure of the Vermelhos Mine and the potential for exploration success 
to meaningfully enhance the near-term base-case grade profile through replacement of lower grade production 
in addition to extending mine life. 

Following the discovery of the Siriema Deposit (within the Vermelhos District) in mid-2019 and, the discovery of 
the high-grade Keel Zone at Siriema at the end of 2019 (including new massive sulphide breccia zones containing 
elevated copper, nickel, cobalt and PGMs), the Company collected and sent a series of samples from each of the 
Company’s  three  primary  operating  districts  of  Vermelhos,  Pilar  and  Surubim  for  additional  PGM  analysis  to 
further evaluate the prevalence of PGMs within the broader Curaçá Valley. Based upon the assay results from this 
initial program, which were delayed due to the impacts of COVID-19, occurrences of elevated PGMs can be found 
throughout the entirety of the Curaçá Valley.  

The  results,  while  preliminary,  demonstrate  that  elevated  PGM  grades  within  the  Curaçá  Valley  occur  in 
association with both the high-sulphide copper and copper-nickel mineralized envelopes of deposits such as the 
Keel Zone of Siriema, as well as outside of the primary copper-mineralized zones where the highest-grade PGM 
samples collected to date occur in low-sulphide reef-style mineralized envelopes lying in zones that traditionally 
would have been classified as waste due to their inherently low association with copper. To date, the Company 
has observed three distinct styles of PGM mineralization, which are supported by relevant examples from the 
early-2020 sample program and previously released multi-element results from within the Keel Zone.  

The Company has commenced a comprehensive program comprised of approximately 5,000 additional samples 
to continue evaluating the potential for additional occurrences of PGMs as well as evaluate continuity of PGM 
mineralization within zones identified to date. Approximately 3,000 samples of the total 5,000 sample program 
have been submitted to third-party laboratories for PGM analysis, and the Company has commenced integrating 
systematic PGM assaying into its ongoing exploration efforts. This effort is supported by the Company’s new in-
house  PGM  assay  capability,  built  in  response  to  early  results  from  this  program.  The  Company  continues  to 
undertake  additional  quality-assurance,  quality-control  procedures  on  its  newly  installed  multi-element 
Inductively Coupled Plasma analytical equipment to transition away from third-party laboratories in the future.

NX Gold S.A. 

At the NX Gold Mine, continued quarter-on-quarter improvement in tonnes and grade mined and processed, along 
with record metallurgical performance, contributed to increased gold production during the period. Production 
during Q4 2020 totaled 10,789 ounces of gold and 6,673 ounces of silver (as by-product) from total mill feed of 
45,574 tonnes grading 7.72 g/t gold after metallurgical recoveries of 95.4% during the period. Ore mined and gold 
production improved in Q4 2020 by 9% and 14%, respectively relative to Q3 2020, and gold production increased 
by 37% as compared to the first quarter of 2020. These quarter-on-quarter improvements have been driven by 
both increases in the number of working faces in operation within the Santo Antonio Vein and improvements in 
metallurgical recoveries. The NX Gold Mine achieved record quarterly C1 cash costs during Q4 2020 of $405 per 
ounce of gold produced, resulting in full-year 2020 C1 cash costs of $457 per ounce of gold produced (see Non-
IFRS Measures). AISC during Q4 2020 averaged $608 per ounce of gold produced resulting in full-year 2020 AISC 
of $628 per ounce of gold produced (see Non-IFRS Measures).  

During  Q4  2020,  the  Company  announced  updated mineral  resources,  mineral  reserves  and  an  updated  LOM 
production plan for the NX Gold Mine encompassing the exploration drill programs conducted during the year.  

The Company’s updated LOM production plan, prepared in conjunction with the updated mineral resource and 
reserve estimate, outlines a six-year LOM with total production of approximately 227,000 ounces and average 
annual  production  of  approximately  41,400  ounces  of  gold  over  the  first  four  years.  In  total,  approximately 
860,000 tonnes of ore are projected to be mined and processed grading an average of approximately 8.80 grams 
per tonne of gold. LOM average C1 cash costs are projected to be US$505 per ounce of gold produced with LOM 
average AISC of US$720 per ounce (see Non-IFRS Measures). 

The updated LOM plan at the NX Gold Mine reflects the culmination of a multi-year commitment to organically 
grow the asset by the Company, beginning in mid-2018 with the first real exploration program conducted at the 
property since 2012. The updated LOM  production plan outlines a highly profitable six-year operation with an 
actionable road-map to further grow production and extend mine-life through conversion of newly defined high-
grade  Inferred  mineral  resources  (573,772  tonnes  grading  10.55  grams  per  tonne  containing  approximately 
194,556 ounces of gold). During the fourth quarter and into 2021, the Company has committed to continue  its 
organic growth efforts at NX Gold as evidenced through the installation of a modular paste-fill plant, expected to 
be operational during the second half of 2021, as well as additional allocation of capital for exploration at the 
mine. The Company ramped up drilling efforts to encompass eight drill rigs at year-end operating on both near-
mine and regional programs throughout the extensive land package controlled by NX Gold.

Please refer to the Company’s press releases dated November 15, 2020 for complete information as it relates to 
the updated LOM production plan for the NX Gold Mine.  

Following the release of the updated LOM, exploration at the NX Gold Mine continued to focus primarily on testing 
down-plunge extensions of the Santo Antonio Vein. Drill results during the period further extended the known 
limits of mineralization within the Santo Antonio Vein. Results are highlighted by the deepest intercept drilled 
within the Santo Antonio Vein drilled to date. In addition, the first regional exploration campaign continued to 
progress at the NX Gold Mine during the period targeting both near-mine targets as well as distal exploration 
targets up to 20 kilometers from the mine.

Boa Esperança 

A full review of the Boa Esperança Feasibility Study[1] remains ongoing with the goal of extending the potential 
mine life and increasing copper production among other desktop optimization initiatives. As a result of an ongoing 
internal  technical  review,  several  potential  opportunities  were  identified  to  optimize  and  further  realize  the 
potential of the Boa Esperança project, including, but not limited to: 

•  Separating  high-grade  and  low-grade  copper  domains  within  the  mineral  resource  estimate  to  better 

• 

optimize mining sequence, mineral reserve conversion and improve overall project economics; 
Increasing the overall size of the open pit, targeting an increase in in-pit mineral reserves, extension of 
mine life and an increase in life-of-mine copper production; 
Implementing bulk ore-sorting with the goal of enhancing mine selectivity; and, 

• 
•  Re-designing  processing  plant  reflecting  optimization  initiatives  around  selective  mining  and  the 

implementation of ore-sorting. 

The  Company’s  technical  team  continues  to  actively  review  these  opportunities  and  is  making  headway  in 
advancing them into actionable deliverables. Should this work continue to yield favorable results, the Company 
will commission an Optimized Feasibility Study (“OFS”), incorporating these initiatives. The Company expects to 
provide additional guidance on these developments mid-year 2021.

1.  Revenues for Q4 2020 from copper sales was $72.6 million (Q4 2019 - $67.7 million), which included the sale of 10,265 copper tonnes 
in concentrate as compared to 11,595 copper tonnes for Q4 2019. The increase in revenues is primarily attributed to higher realized 
prices, partially offset by lower sales volume. Revenues for Q4 2020 from gold sales was $18.6 million (Q4 2019 - $8.0 million), which 
included the sale of 10,100 ounces of gold, compared to 5,810 ounces of gold for Q4 2019, at a significantly higher average gold price 
than in the comparative quarter. 

2.  Cost of product sold for Q4 2020 from copper sales was $25.8 million (Q4 2019 - $35.6 million) which consisted of $8.0 million (Q4 
2019 - $11.1 million) in depreciation and depletion, $6.2 million (Q4 2019 - $9.4 million) in salaries and benefits, $3.8 million (Q4 2019 
- $4.6 million) in materials and consumables, $3.1 million (Q4 2019 - $3.9 million) in maintenance costs, $2.9 million (Q4 2019 - $4.3 
million) in contracted services, $1.7 million (Q4 2019 - $2.2 million) in utilities, and $0.1 million (Q4 2019 - $0.2 million) in other costs.     

Cost of product sold for Q4 2020 from gold sales was $5.5 million (Q4 2019 - $7.4 million) which primarily comprised of $1.4 million 
(Q4 2019 - $2.2 million) in salaries and benefits, $1.2 million (Q4 2019 - $0.9 million) in depreciation and depletion, $1.1 million (Q4 
2019 - $1.2 million) in contracted services, $0.9 million (Q4 2019 - $1.1 million) in materials and consumables, $0.5 million (Q4 2019 - 
$0.7 million) in utilities, and $0.4 million (Q4 2019 - $1.2 million) in maintenance costs. 

The overall decrease in cost of product sold in Q4 2020 as compared to Q4 2019 is primarily attributable to the weakened BRL, in 
which cost is incurred, against the USD, in which cost is reported. 

3.  General and administrative expenses for Q4 2020 include $5.0 million (Q4 2019 - $10.3 million) with respect to MCSA for salaries and 
incentive payments, professional fees, office and sundry and provisions for tax, legal and labour claims, $0.6 million (Q4 2019 - $0.5 
million) with respect to NX Gold for salaries and incentive payments, professional fees, office and sundry and provisions for tax, legal 
and labour claims, and $2.6 million (Q4 2019 - $1.9 million) with respect to the corporate head office in Vancouver. Corporate head 
office costs are primarily comprised of $2.2 million (Q4 2019 - $1.4 million) in salaries, incentive payments, and consulting fees, $0.2 
million (Q4 2019 - $0.2 million) in accounting and legal costs, and $0.2 million (Q4 2019 - nominal) in office and sundry costs. General 
and administrative expenses in Q4 2020 decreased from that in Q4 2019, primarily attributable to a decrease in incentive payments, 
and a weakened BRL, in which costs from MCSA and NX Gold are incurred, against the USD, in which cost is reported.

Finance expense for Q4 2020 was $2.6 million (Q4 2019 - $2.0 million) and is primarily comprised of interest on loans at the corporate 
head office of $1.6 million (Q4 2019 - $2.0 million), interest on loans and borrowings at MCSA and NX Gold of $0.5 million (Q4 2019 - 
$0.7 million), loss on interest rate swap derivatives of $0.7 million (Q4 2019 - $0.2 million gain), accretion of the asset retirement 
obligations of $0.2 million (Q4 2019 - $0.2 million recovery), and nominal commitment fees (Q4 2019 - $0.5 million), partially offset by 
other finance income of $0.6 million (Q4 2019 - $1.0 million). 

Foreign exchange gain for Q4 2020 was $27.1 million (Q4 2019 - $4.4 million). This amount is primarily comprised of foreign exchange 
gain on unrealized derivative contracts of $27.7 million (Q4 2019 - $1.4 million) and a foreign exchange gain on USD denominated debt 
of $7.7 million (Q4 2019 - $3.8 million) in MCSA for which the functional currency is the BRL, partially offset by  a realized foreign 
exchange loss on derivative contracts of $7.8 million (Q4 2019 - $0.5 million) and other foreign losses of $0.4 million (Q4 2019 - $0.2 
million gain). The foreign exchange gains were primarily a result of a strengthening of BRL against USD in Q4 2020 as compared to the 
prior quarter. The foreign exchange gains on unrealized derivative contracts are a result of mark-to-market calculations at period end 
and  may  not  represent  the  amount  that  will  ultimately  be  realized,  which  will  depend  on  future  changes  to  the  USD/BRL  foreign 
exchange rates. 

In  Q4  2020,  the  Company  recognized  a  recovery  of  $8.9  million  (Q4  2019  -  $nil)  in  net  income  related  to  value  added  taxes.  The 
recovery  was  recognized  as  a  result  of  a  study  conducted  to  revisit  certain  tax  positions  which  concluded  that  it  is  probable  that 
additional tax credits are available to be used to offset a variety of taxes. 

In  Q4  2020,  the  Company  recognized  $13.2  million  in  income  tax  expense  (Q4  2019  -  $25.2  million  recovery).  Income  taxes  from 
operations  are  partially  offset  by  the  recognition  of  temporary  deductible  differences  associated  with  MCSA’s  unrealized  foreign 
exchange losses on derivatives and loans and borrowings denominated in USD. In Q4 2019 the Company recognized a $25.2 million 
income tax recovery, primarily resulting from the recognition of previously unrecognized available tax losses and tax credits in MCSA, 
partially offset by current tax expense in the period. At December 31, 2019 the Company considered taxable income generated since 
acquisition of MCSA and forecasted future taxable income and determined that it was probable that the benefit of these losses and 
tax credits in MCSA would be realized.   

8. 

The foreign currency translation gain is a result of a strengthening of the BRL against the USD during Q4 2020 when translating the net 
assets of the Company’s Brazilian subsidiaries to USD for presentation in the Company’s consolidated financial statements.

Notes: 

1.  Revenues for Fiscal 2020 from copper sales was $260.9 million (Fiscal 2019 - $246.2 million), which included the sale of 42,813 copper 
tonnes in concentrate as compared to 42,759 copper tonnes for Fiscal 2019. Revenues for Fiscal 2020 from gold sales was $63.2 million 
(Fiscal 2019 - $38.6 million), which included the sale of 35,855 ounces of gold, compared to 29,755 ounces of gold for Fiscal 2019, at 
a significantly higher average gold price than the comparative period. The increase in revenues is primarily attributed to higher realized 
prices from copper and gold sales. 

2.  Cost of product sold for Fiscal 2020 from copper sales was $109.6 million (Fiscal 2019 - $135.6 million) which consisted of $35.7 million 
(Fiscal 2019 - $40.1 million) in depreciation and depletion, $24.6 million (Fiscal 2019 - $33.7 million) in salaries and benefits, $15.1 
million (Fiscal 2019 - $17.9 million) in materials and consumables, $14.8 million (Fiscal 2019 - $20.5 million) in contracted services, 
$12.5 million (Fiscal 2019 - $14.1 million) in maintenance costs, $6.5 million (Fiscal 2019 - $8.7 million) in utilities, and $0.4 million 
(Fiscal 2019 - $0.7 million) in other costs.     

Cost of product sold for Fiscal 2020 from gold sales was $21.0 million (Fiscal 2019 - $27.2 million) which primarily comprised of $5.5 
million (Fiscal 2019 - $7.1 million) in salaries and benefits, $3.8 million (Fiscal 2019 - $3.9 million) in materials and consumables, $3.7 
million (Fiscal 2019 - $3.2 million) in contracted services, $3.5 million (Fiscal 2019 - $5.9 million) in depreciation and depletion, $2.2 
million (Fiscal 2019 - $2.5 million) in utilities, $2.1 million (Fiscal 2019 - $4.3 million) in maintenance costs, and $0.2 million (Fiscal 2019 
- $0.3 million) in other costs. 

The overall decrease in cost of product sold for Fiscal 2020 as compared to Fiscal 2019 is primarily attributable to the weakened BRL, 
in which cost of products sold are incurred, against the USD, in which cost is reported. 

3.  General and administrative expenses for Fiscal 2020 include $16.5 million (Fiscal 2019 - $21.0 million) with respect to MCSA for salaries 
and incentive payments, professional fees, office and sundry and provisions for tax, legal and labour claims, $1.7 million (Fiscal 2019 - 
$2.3 million) with respect to NX Gold for salaries and incentive payments, professional fees, office and sundry and provisions for tax, 
legal and labour claims, and $9.7 million (Fiscal 2019 - $9.5 million) with respect to the corporate head office in Vancouver. Corporate 
head office costs are primarily comprised of $7.3 million (Fiscal 2019 - $6.7 million) in salaries, incentive payments, and consulting 
fees, $0.9 million (Fiscal 2019 - $0.7 million) in office and sundry costs, $0.5 million (Fiscal 2019 - $1.2 million) in travel-related costs, 
$0.5 million (Fiscal 2019 - $0.5 million) in professional fees, and $0.3 million (Fiscal 2019 - $0.2 million) in transfer agent and filing fees.  

General and administrative expenses in Fiscal 2020 decreased compared to that in Fiscal 2019, reflecting slightly lower general and 
administrative  expenses  at  the  corporate  head  office  from  reduced  consulting  fees  and  travel-related  costs  during  a  period  of 
pandemic-imposed travel restrictions, and the weakening of the BRL, in which costs from MCSA and NX Gold are incurred, against the 
USD, in which cost is reported. 

Finance expense for Fiscal 2020 was $15.4 million (Fiscal 2019 - $20.4 million) and was primarily comprised of interest on loans at the 
corporate head office of $6.7 million (Fiscal 2019 - $8.3 million), interest on loans and borrowings at MCSA and NX Gold of $3.2 million 
(Fiscal 2019 - $3.0 million), loss on interest rate swap derivatives of $2.7 million (Fiscal 2019 - $1.8 million), other finance expenses of 
$1.2 million (Fiscal 2019 - $1.8 million), and accretion of asset retirement obligations of $0.9 million (Fiscal 2019 - $3.5 million). 

Foreign exchange loss for Fiscal 2020 was $79.8 million (Fiscal 2019 - $5.1 million). This amount was primarily comprised of a foreign 
exchange  loss  on  unrealized  derivative  contracts  of  $34.5  million  (Fiscal  2019  -  $0.3  million),  a  foreign  exchange  loss  on  USD 
denominated debt of $24.2 million (Fiscal 2019 - $4.4 million) in MCSA for which the functional currency is the BRL, and a realized 
foreign exchange loss on derivative contracts of $20.8 million (Fiscal 2019 - $1.0 million). The foreign exchange losses were primarily 
a result of a strengthening of the USD against the BRL during a time of worldwide instability as a result of the COVID-19 pandemic. The 
foreign  exchange  loss  on  unrealized  derivative  contracts  are  a  result  of  mark-to-market  calculations  at  period  end  and  may  not 
represent the amount that will ultimately be realized, which will depend on future changes to the USD/BRL foreign exchange rates. 

In  Fiscal  2019,  the  Company  recognized  a  loss  on  debt  settlement  of  $1.8  million,  which  represented  the  difference  between  the 
accounting fair value made to legally extinguish a bank loan held by MCSA and the carrying value of the loan at the time. 

In  Fiscal  2020,  the  Company  recognized  a  recovery  of  $8.9  million  in  net  income  related  to  value  added  taxes.  The  recovery  was 
recognized as a result of a study conducted to revisit certain tax positions which concluded that it is probable that additional tax credits 
are available to be used to offset a variety of taxes.

7. 

In Fiscal 2019, the Company recognized a recovery of $21.6 million in net income related to value added taxes previously paid on sales 
in  Brazil.  The  recovery  was  recognized  as  a  result  of  a  Brazil  Supreme  Court  ruling  in  2017  that  concluded  that  the  relevant  tax 
authorities had historically used an incorrect methodology to determine such taxes. The ruling set a precedent for all companies in 
Brazil but was required to be confirmed for the Company’s specific claim, which approval was received in July 2019. These credits can 
be used to offset a variety of other taxes, including taxes on future sales.

9. 

In Fiscal 2020, the Company recognized a $8.9 million income tax expense (Fiscal 2019 - income tax recovery of $17.6 million), primarily 
comprised  of  current  tax  arising  from  taxable  income  in  mining  operations.  In  Fiscal  2019,  the  Company  recognized  a  significant 
deferred income tax recovery primarily resulting from the recognition of previously unrecognized available tax losses and tax credits 
in MCSA, partially offset by current tax expense in the period. At December 31,  2019 the Company considered the taxable income 
generated since the acquisition of MCSA, forecasted future taxable income, and determined that it was considered probable that the 
benefit of those losses and tax credits in MCSA would be realized. Accordingly, a tax recovery of $25.2 million was recognized related 
to these losses in 2019. 

The foreign currency translation loss is a result of a strengthening of the USD against the BRL during a time of worldwide instability as 
a result of the COVID-19 pandemic when translating the net assets of the Company’s Brazilian subsidiaries to USD for presentation in 
the Company’s consolidated financial statements.  

SUMMARY OF QUARTERLY RESULTS 

The following table presents selected financial information for each of the most recent eight quarters. Tabular 
amounts are in millions of US Dollars, except share and per share amounts. 

Notes: 
1.  During  Q4  2020,  the  Company  recognized  $27.1  million  in  foreign  exchange  gains.  The  foreign  exchange  gains  were  primarily 
comprised  of  foreign  exchange  gain  on  unrealized  derivative  contracts  of  $27.7  million  and  a  foreign  exchange  gain  on  USD 
denominated debt of $7.7 million in MCSA for which the functional currency is the BRL, partially offset by a realized foreign exchange 
loss on derivative contracts of $7.8 million and other foreign losses of $0.4 million. The foreign exchange gains were primarily a result 
of a strengthening of BRL against USD in Q4 2020. The foreign exchange gains on unrealized derivative contracts are a result of mark-
to-market calculations at period end and may not represent the amount that will ultimately be realized, which will depend on future 
changes to the USD/BRL foreign exchange rates.  

During Q4 2020, the Company recognized a recovery of $8.9 million in net income related to value added taxes. The recovery was 
recognized as a result of a study conducted to revisit certain tax positions which concluded that it is probable that additional tax credits 
are available to be used to offset a variety of taxes. 

2.  During the  quarter ended June 30, 2020, the Company had an  overall net income of $7.7 million, despite $16.3 million in foreign 
exchange losses. The foreign exchange losses were comprised of a foreign exchange loss on unrealized derivative contracts of $8.5 
million, a foreign exchange loss on realized derivative contracts of $4.4 million, and a foreign exchange loss on USD denominated debt 
of $3.0 million in MCSA for which the functional currency is the BRL. As with the preceding quarter, the foreign exchange losses were 
unusually high this quarter due to volatility in the foreign exchange rates between the  USD and BRL resulting from the worldwide 
instability in currency rates as a result of the COVID-19 pandemic. 

3.  During the quarter ended March 31, 2020, the Company recognized a $81.9 million in foreign exchange losses. The foreign exchange 
losses were mainly comprised of a $26.9 million loss associated with USD denominated debt held by MCSA, whose functional currency 
is the BRL, and $52.7 million losses associated with unrealized losses on foreign exchange currency  collar contracts. These foreign 
exchange losses were unusually high this quarter due to volatility in the foreign exchange rates between the USD and the BRL resulting 
from the worldwide instability in currency rates as a result of the COVID-19 pandemic.

4.  During Q4 2019, the Company recognized a $25.2 million income tax recovery primarily resulting from the recognition of available tax 
losses and tax credits in MCSA. At December 31, 2019, the Company considered the taxable income generated since acquisition of 
MCSA and forecasted future taxable income and determined that it was now considered probable that the benefit of these losses and 
tax credits in MCSA would be realized. 

5.  During the quarter ended September 30, 2019, the Company recognized a recovery of $21.6 million in net income related to value 
added taxes previously paid on sales in Brazil.  The recovery was recognized as a result of a Brazil Supreme Court ruling in 2017 that 
concluded that the relevant taxing authorities had historically used an incorrect methodology to determine such taxes.  The ruling set 
a precedent for all companies in Brazil but was required to be confirmed for the Company’s specific claim,  for which approval was 
received in July 2019.  These credits can be used to offset a variety of other taxes, including income taxes and taxes on future sales.

The Company’s primary sources of capital are comprised of cash from operations, and cash and cash equivalents 
on hand. The Company will continuously monitor its capital structure and, based on changes in operations and 
economic conditions, may adjust such structure by issuing new common shares or new debt as necessary. While 
the Company has been successful in securing financing to date, there are no guarantees that it will be able to 
secure such financing in the future on terms acceptable to the Company, if at all. Taking into consideration cash 
flow from existing operations, management believes that the Company has sufficient working capital and financial 
resources to maintain its planned operations and activities for the foreseeable future.

At December 31, 2020, we had unrestricted cash and cash equivalents of $62.5 million compared to $21.5 million 
at December 31, 2019. The increase is primarily due to an increase in cash from operations.  

The Company’s $150 million Facilities are fully drawn at December 31, 2020. The Company is required to comply 
with  certain  financial  covenants.  As  of  the  date  of  the  consolidated  financial  statements,  the  Company  is  in 
compliance  with  these  covenants.  Subsequent  to  December  31,  2020,  the  Company  amended  terms  of  the 
Facilities. Refer to sub-section titled “Q4 2020 Financial Report” within the “Highlights” section in this MD&A. 

Contractual Obligations and Commitments 

Certain loan agreements contain operating and financial covenants that could restrict the ability of the Company 
and its  subsidiaries, MCSA, Ero Gold,  and NX  Gold S.A., to, among other things, incur additional indebtedness 
needed to fund its respective operations, pay dividends or make other distributions, make investments, create 
liens, sell or transfer assets or enter into transactions with affiliates. There are no other restrictions or externally 
imposed capital requirements of the Company. 

MANAGEMENT OF RISKS AND UNCERTAINTIES 

The Company thoroughly examines the various financial instruments and risks to which it is exposed and assesses 
the impact and likelihood of those risks. These risks may include credit risk, liquidity risk, currency risk, commodity 
price risk and interest rate risk. Where material, these risks are reviewed and monitored by the Board. 

COVID-19 Pandemic Risk 

The  outbreak  of  COVID-19  has  had  a  significant  impact  on  the  volatility  of  commodity  prices  and  USD/BRL 
exchange rates, and governmental actions to contain the outbreak may impact our ability to transport or market 
our  concentrate or  cause disruptions  in  our  supply  chains  or  interruption  of  production.  A material  spread  of 
COVID-19 in jurisdictions where we operate could impact our ability to staff operations. A reduction in production 
or  other  COVID-19  related  impacts,  including  but  not  limited  to,  low  copper  prices  could  cause  a  significant 
reduction in profitability of ongoing operations. 

The global pandemic could cause temporary closure of businesses in regions that are significantly impacted by the 
health crises, or cause  governments to take  or continue  to take  preventative measures such as the  closure of 
points of entry, including ports and borders. 

Credit risk  

Credit risk is the risk of financial loss to the Company if a customer or counterparty to a financial instrument fails 
to meet its contractual obligations and arises principally from the Company’s receivables from customers. The 
carrying amount of the financial assets below represents the maximum credit risk exposure as at December 31, 
2020 and December 31, 2019: 

The Company invests cash and cash equivalents with financial institutions that are financially sound based on their 
credit rating. The Company’s exposure to credit risk associated with accounts receivable is influenced mainly by 
the individual characteristics of each customer. The Company currently has only three significant customers, all of 
which have no history of credit default with the Company. The Company has not incurred credit losses during the

year ended December 31, 2020 nor recognized a provision for credit losses.     

Liquidity risk  

Liquidity  risk  is  the  risk  associated  with  the  difficulties  that  the  Company  may  have  meeting  the  obligations 
associated  with  financial  liabilities  that  are  settled  with  cash  payments  or  with  another  financial  asset.  The 
Company's approach to liquidity management is to ensure as much as possible that sufficient liquidity exists to 
meet their maturity obligations on the expiration dates, under normal and stressful conditions, without causing 
unacceptable losses or with risk of undermining the normal operation of the Company.  

The table below shows the Company's maturity of non-derivative financial liabilities on December 31, 2020: 

The  Company  also  has  derivative  financial  liabilities  for  foreign  exchange  and  interest  rate  derivatives  whose 
notional amounts and maturity information is disclosed below under foreign exchange currency risk and interest 
rate risk. 

Foreign exchange currency risk  

The Company may use derivatives, including forward contracts, collars and swap contracts, to manage market 
risks. At December 31, 2020, the Company has entered into foreign exchange collar contracts at  zero cost  for 
notional amounts of $285.7 million with an average floor rate of 4.05 BRL to US Dollar and an average cap rate of 
4.76 BRL to US Dollar (December 31, 2019 - notional amount of $336.6 million in foreign exchange forward collar 
contracts). The maturity dates of these contracts are from January 27, 2021 to July 27, 2022 and are financially 
settled on a net basis. The fair value  of these  contracts at December 31, 2020 was  a liability of $34.5 million, 
(December 31, 2019 - $nil) which is included in Derivatives in the statement of financial position. The fair value of 
these forward contracts as at December 31, 2020 was determined using an option pricing mode with the following 
assumptions:  discount  rate  of  5.015%,  foreign  exchange  rate  of  approximately  5.20,  and  volatility  of  7.46%  - 
21.20%. The change in fair value of foreign exchange collar contracts was a loss of $34.5 million for the year ended 
December 31, 2020 (a loss of $0.3 million for the year ended December 31, 2019) and has been recognized in 
foreign exchange loss.  In addition, during the year ended December 31, 2020, the Company recognized a realized 
loss of $20.8 million ($1.0 million for the year ended December 31, 2019) related to the settlement of foreign 
currency forward collar contracts. 

Interest rate risk 

The Company is principally exposed to the variation in interest rates on loans and borrowings with variable rates 
of interest. Management reduces interest rate risk exposure by entering into loans and borrowings with fixed 
rates of interest or by entering into derivative instruments that fix the ultimate interest rate paid. 

The Company is principally exposed to interest rate risk through its Term Facilities of $150.0 million, Brazilian Real 
denominated bank loans of $4.5 million, Brazilian Real denominated lines of credit of $1.4 million, and Brazilian 
Real denominated equipment finance loans of $1.1 million.  Based on the Company’s net exposure at December 
31, 2020, a 1% change in the variable rates would have an impact of $1.6 million on pre-tax annual net income, 
without consideration of the effects of the interest rate swap contract below.

In order to mitigate the above volatility due to variable rates on loans, as at December 31, 2020, the Company has 
entered  into  an  interest  rate  swap  contract  to  manage  interest  rate  risk.  At  December  31,  2020,  the  floating 
interest on a notional amount of $60.0 million was swapped for a fixed interest rate of 2.69%. This interest rate 
swap transaction is in effect for the majority of the term of the Company’s term facility, with the notional amount 
reduced over time. The fair value of this contract at December 31, 2020 was a liability of $2.5 million (December 
31, 2019 - $1.7 million) and was included in Derivatives in the statement of financial position. The fair value of this 
swap contracts as at December 31, 2020 was determined using a discounted cash flow model with the following 
assumptions: discount rates of 0.017%  – 0.298%  and forward foreign exchange  rates of 0.421%  - 0.164%. The 
realized loss on the interest rate swap contract was $1.2 million for the year ended December 31, 2020 (realized 
loss of $0.1 million for the year ended December 31, 2019) and was included in finance expense. In addition, the 
Company  recognized  an  unrealized  loss  of $0.8  million  on  the  interest  rate  swap  contract  for  the year  ended 
December 31, 2020 (unrealized loss of $1.6 million for the year ended December 31, 2019), which was included 
in finance expense. 

In addition, as at December 31, 2020, MCSA has entered into an interest rate and currency swap contract on the 
Plural Loan.  At December 31, 2020, the floating interest on a notional amount of BRL $12 million was swapped 
for a fixed interest rate of 9.9% and the BRL currency on the loan was swapped for USD at a rate of 3.95.  The fair 
value of this contract at December 31, 2020 was a liability of $0.3 million (December 31, 2019 - nil) and is included 
in Derivatives in the statement of financial position. The realized loss on this swap contract was $0.4 million for 
the year ended December 31, 2020 and was included in finance expense. In addition, the Company recognized an 
unrealized  loss  of  $0.3  million  on  the  swap  contract  for  the  year  ended  December  31,  2020,  which  was  also 
included in finance expense.   

Price risk 

The Company may use derivatives, including forward contracts, collars and swap contracts, to manage commodity 
price risks. At December 31, 2020, the Company has not entered into any commodity derivative contracts. The 
Company  recognized  a  realized  loss  of  $1.4  million  for  the  year  ended  December  31,  2019  related  to  the 
settlement of commodity forward contracts. 

For  a  discussion  of  additional  risks  applicable  to  the Company  and  its  business and  operations,  including risks 
related to the Company’s foreign operations, the environment and legal proceedings, see “Risk Factors” in the 
Company’s Annual Information Form for the year ended December 31, 2020 and dated March 16, 2021 (the “AIF”). 

OTHER FINANCIAL INFORMATION 

Off-Balance Sheet Arrangements 

As at December 31, 2020, the Company had no material off-balance sheet arrangements.  

Contingencies 

MCSA is subject to a number of claims (including claims related to tax, labour and social security matters and civil 
action)  in  the  course  of  its  business  which  individually  are  not  material  and  have  not  been  accrued  for  in  the 
Company’s financial statements as it is not probable that a material cash outflow will occur. While the Company 
believes  that  these  claims  are  unlikely  to  be  successful,  if  all  such  existing  claims  were  decided  against  it,  the 
Company could be exposed to a liability of up to approximately $21.8 million as at December 31, 2020 (December 
31, 2019  -  $31.1 million), which could have  an adverse impact on the Company’s business, financial condition, 
results of operations, cash flows or prospects.  

Outstanding Share Data 

At March 16, 2021, the Company had 88,101,909 common shares, 4,485,781 stock options, 1,533,330 warrants, 
and 727,761 performance share units issued and outstanding.

Related Party Disclosures 

For the three months and year ended December 31, 2020, amounts paid to related parties were incurred in the 
normal  course  of  business  and  measured  at  the  exchange  amount,  which  is  the  amount  agreed  upon  by  the 
transacting parties and on terms and conditions similar to non-related parties.  

The aggregate value of compensation paid to key management personnel for the year ended December 31, 2020 
was $7.4 million ($7.5 million for the year ended December 31, 2019).  In addition, 287,281 options, 197,269 share 
units and 79,230 DSUs were issued to key management personnel and non-executive directors during the year 
ended December 31, 2020 (444,265 options and 171,754 share units for the year ended December 31, 2019). For 
key  management  personnel,  $5.1  million  was  recognized  in  share-based  compensation  expense  for  the  year 
ended December 31, 2020 for options, share units, and DSUs issued ($4.1 million for the year ended December 
31, 2019).   

During the year ended December 31, 2020, key management personnel exercised 408,555 options and 1,266,666 
warrants for total cash proceeds to the Company of $2.7 million (286,666 options and 300,000 warrants for total 
cash proceeds of $1.0 million for the year ended December 31, 2019). 

As at December 31, 2020, $3.7 million was payable to key management as incentive compensation and is included 
in  accounts  payable  and  accrued  liabilities  in  the  statement  of  financial  position  (December  31,  2019  -  $3.9 
million). Such amounts are unsecured, non-interest bearing and will be paid under normal trade terms. 

ACCOUNTING POLICIES, JUDGMENTS AND ESTIMATES 

Critical Accounting Judgments and Estimates 

The  preparation  of  consolidated  financial  statements  in  conformity  with  IFRS  requires  management  to  make 
judgments,  estimates  and  assumptions  about  future  events  that  affect  the  reported  amounts  of  assets  and 
liabilities at the date of the financial statements and the reported amounts of revenue and expenses during the 
reporting period. Although these estimates are based on management’s best knowledge of the amount, events 
or actions, actual results may differ from these estimates.  

The  Company’s  significant  accounting  policies  and  accounting  estimates  are  contained  in  the  Company’s 
December  31,  2020  consolidated  financial  statements.  Certain  of  these  policies,  such  as,  capitalization  and 
depreciation  of  property,  plant  and  equipment  and  mining 
instruments,  and 
decommissioning liabilities provisions involve critical accounting estimates because they require management of 
the Company to make subjective or complex judgments about matters that are inherently uncertain, and because 
of the likelihood that materially different amounts could be reported under different conditions or using different 
assumptions.  

interests,  derivative 

In preparing its financial statements, management has made judgments, estimates and assumptions that affect 
the application of the Company’s accounting policies and the reported amounts of the assets, liabilities, revenues, 
and expenses.  Actual results may differ from these estimates.   

The  estimates  and  assumptions  are  reviewed  on  an  ongoing  basis.  Revisions  to  estimates  are  recognized 
prospectively.

Critical Judgments  

Functional currency 

The  functional  currency of  the  Company  and  each of  its  subsidiaries  is  the  currency  of  the  primary  economic 
environment in which the entities operate.  The Company has determined that the functional currency for the 
Company is the US dollar while the functional currency for MCSA and NX Gold is the Brazilian Real. Assessment of 
functional  currency  involves  certain  judgements  to  determine  the  primary  economic  environment  and  the 
Company reconsiders the functional currency of its entities if there is a change in events and conditions which 
determined the primary economic environment. 

Legal claims and contingent liabilities 

The recognition of legal provisions and contingent liabilities involves the assessment of claims made against the 
Company and each of its subsidiaries.  The recognition of a legal provision, or disclosure of a contingent liability, 
involves certain judgements to determine the probability of whether a cash outflow will occur.  In making this 
judgment, management has assessed various criteria and also relies on the opinions of its legal advisers to assist 
in making this assessment. 

Key Sources of Estimation Uncertainty  

The preparation of financial statements in conformity with IFRS requires management  to make estimates and 
assumptions that affect the reported amounts of assets and liabilities and the disclosure of assets and liabilities 
at the date of the consolidated financial statements and the reported amounts of expenses during the reporting 
periods.  Actual  results  could  differ  from  those  estimates  and  such  differences  could  be  significant.  Significant 
estimates made by management affecting the consolidated financial statements include:  

Derivative instruments 

The fair value of derivative  instruments is determined using either present value  techniques  or option pricing 
models that utilize a variety of inputs that are a combination of quoted prices and market-corroborated inputs, 
including assumptions for forward interest and foreign exchange rates, volatilities  and discount rates. The fair 
value of the Company’s derivative contracts includes an adjustment for credit risk for either the Company or the 
counter party as applicable. Changes in the assumptions for inputs into the models affect the fair value of the 
derivatives recognized in the statement of financial position as well as the unrealized gains or losses recognized 
in net income.   

Mineral reserve and resource estimates including life of mine plan 

The Company estimates its mineral reserves and mineral resources based on information compiled by competent 
individuals.    Mineral  reserves  are  used  in  the  calculation  of  depreciation,  impairment  assessments  and  for 
forecasting the timing of payment of mine closure and rehabilitation costs. 

There are numerous uncertainties inherent in estimating mineral reserves, and assumptions that are valid at the 
time of estimation may change significantly when new information becomes available.  Changes in the estimation 
methodology, forecasted prices of commodities, exchange rates, production costs or recovery rates may change 
the economic status of mineral reserves and may, ultimately, result in changes in the mineral reserves. 

The carrying amounts of the Company’s mineral properties, plant and equipment are depleted in part based on 
recoverable  mineral  reserve  tonnes  processed,  depending  on  the  use  of  the  asset.    Changes  to  estimates  of 
recoverable quantities of metals, mineral reserve tonnes and depletable costs, including changes resulting from 
revisions to the Company’s mine plans and changes in metals prices forecasts, can result in a change to future

depreciation and depletion rates and may result in impairment charges. 

Mine closure and rehabilitation costs 

Significant estimates and assumptions are made in determining the provision for mine closure and rehabilitation 
as there are numerous factors that will affect the ultimate liability payable.  These factors include estimation of 
the  extent  and  cost  of  rehabilitation  activities,  timing  of  future  cash  flows,  discount  rates,  inflation  rate,  and 
regulatory requirements. 

Changes in the above factors can result in a change to the provision recognized by the Company.  Changes to mine 
closure and rehabilitation costs are recorded with a corresponding change  to the  carrying amounts of related 
mineral properties, plant and equipment.  Adjustments to the carrying amounts of related mineral properties, 
plant and equipment can result in a change to future depreciation and depletion expense. 

Significant assumptions used to determine mine closure and rehabilitation costs are included in Note 11(a) to the 
consolidated financial statements.  

Income taxes 

The determination of the Company’s tax expense for the period and deferred tax assets and liabilities involves 
significant estimation and judgement by management. In determining these amounts, management interprets tax 
legislation in a variety of jurisdictions and makes estimates of the expected timing of the reversal of deferred tax 
assets  and  liabilities.  Management  also  makes  estimates  of  future  earnings,  which  affect  the  extent  to  which 
potential future tax benefits may be used. The Company is subject to assessments by various taxation authorities, 
which may interpret legislation differently. These differences may affect the final amount or the timing of the 
payment  of  taxes.  The  Company  provides  for  such  differences  where  known  based  on  management’s  best 
estimate of the probable outcome of these matters. 

The Company operates in Brazil where tax authorities may audit income tax treatments and the resolution of such 
audits  may  span  multiple  years.  Tax  law  in  Brazil  is  complex  and  often  subject  to  changes  and  to  varied 
interpretations; accordingly, the ultimate outcome with respect to income tax treatments may differ from the 
amounts recognized. The Company’s assessment of whether it is probable that uncertain income tax treatments 
will be accepted by tax authorities in Brazil is a significant management judgment. 

New Accounting Standards and Interpretations Adopted in the Year 

The following new and amended IFRS pronouncements were adopted effective January 1, 2020 and had no impact 
to the Company’s financial statements: 

•  Amendments to References to the Conceptual Framework in IFRS Standards 
• 

In September 2019, the IASB issued first phase amendments IFRS 9 Financial Instruments, IAS 39 Financial 
Instruments: Recognition and Hedging, and IFRS 7 Financial Instrument Disclosures to address the financial 
reporting impact of the reform on interest rate benchmarks, such as the discontinuance of the interbank 
offered rates. The first phase amendment is focused on the impact to hedge accounting requirements. The 
Company  adopted  the  first  phase  amendment  and  there  was  no  material  impact  on  its  consolidated 
financial statements. The Company will continue to assess the effect of amendments related to the interest 
rate benchmark reform on its consolidated financial statements. 

The  following  amendment  to  accounting  standards  has  been  issued  but  not  yet  adopted  in  the  financial 
statements: 

•  On May 14, 2020, the IASB published a narrow scope amendment to IAS 16 Property, Plant and Equipment 
- Proceeds before Intended Use. The amendment prohibits deducting from the cost of property, plant and 
equipment amounts received from selling items produced while preparing the asset for its intended use. 

E R O   C O P P E R  |     2 0 2 0   A N N U A L   R E V I E W     |   3 2  

 
 
 
 
 
 
 
 
 
 
Instead,  amounts  received  will  be  recognized  as  sales  proceeds  and  related  cost  in  profit  or  loss.  The 
effective date is for annual periods beginning on or after January 1, 2022. The Company does not expect 
to  adopt  this  amendment  until  the  effective  date,  and  does  not  anticipate  a  material  impact  on  its 
consolidated financial statements.

Capital Expenditures 

The following table presents capital expenditures at the Company’s operations. 

NON-IFRS MEASURES 

Financial results of the Company are prepared in accordance with IFRS. The Company utilizes certain non-IFRS 
measures, including C1 cash cost of copper produced (per lb), C1 cash cost of gold produced (per ounce), AISC of 
gold  produced  (per  ounce),  EBITDA,  Adjusted  EBITDA,  Adjusted  net  income  attributable  to  owners  of  the 
Company, Adjusted net income per share, net debt, working capital (deficit) and available liquidity, which are not 
measures recognized under IFRS. The Company believes that these measures, together with measures determined 
in accordance with IFRS, provide investors with an improved ability to evaluate the underlying performance of the 
Company. Non-IFRS measures do not have any standardized meaning prescribed under IFRS, and therefore they 
may  not  be  comparable  to  similar  measures  employed  by  other  companies.  The  data  is  intended  to  provide 
additional information and should not be considered in isolation or as a substitute for measures of performance 
prepared in accordance with IFRS.  The tables below provide a reconciliation of these non-IFRS measures to the 
most directly comparable IFRS measures as contained in the Company’s financial statements. 

Unless otherwise noted, the non-IFRS measures presented below have been calculated on a consistent basis for 
the periods presented.

C1 Cash Cost of Copper Produced (per lb)  

C1 cash cost of copper produced (per lb) is the sum of production costs, net of capital expenditure development 
costs and by-product credits, divided by the copper pounds produced. C1 cash costs reported by the Company 
include  treatment,  refining  charges,  offsite  costs,  and  certain  tax  credits  relating  to  sales  invoiced  to  the 
Company’s Brazilian customer on sales. By-product credits are calculated based on actual precious metal sales 
(net of treatment costs) during the period divided by the total pounds of copper produced during the period. C1 
cash cost of copper produced per pound is a non-IFRS measure used by the Company to manage and evaluate 
operating performance of the Company’s operating mining unit and is widely reported in the mining industry as 
benchmarks  for  performance  but  does  not  have  a  standardized  meaning  and  is  disclosed  in  addition  to  IFRS 
measures.   

The following table provides a reconciliation of C1 cash cost of copper produced per pound to cost of goods sold, 
its most directly comparable IFRS measure.

C1 Cash Cost of Gold produced (per ounce) and AISC of Gold produced (per ounce)  

C1 cash cost of gold produced (per ounce) is the sum of production costs, net of capital expenditure development 
costs and silver by-product credits, divided by the gold ounces produced.  By-product credits are calculated based 
on actual precious metal sales during the period divided by the total ounces of gold produced during the period.  
C1 cash cost of gold produced per ounce is a non-IFRS measure used by the Company to manage and evaluate 
operating performance of the Company’s operating mining unit and is widely reported in the mining industry as 
benchmarks  for  performance  but  does  not  have  a  standardized  meaning  and  is  disclosed  in  addition  to  IFRS 
measures.   

AISC of gold produced (per ounce) is the sum of production costs, site general and administrative costs, accretion 
of mine closure and rehabilitation provision, sustaining capital expenditures, sustaining leases, and royalties and 
production taxes, net of silver by-product credits, divided by the gold ounces produced. By-product credits are 
calculated based on actual precious metal sales during the period divided by the total ounces of gold produced 
during the period. All-in sustaining cost of gold produced per ounce is a non-IFRS measure used by the Company 
to manage and evaluate operating performance of the Company’s operating mining unit and is widely reported in 
the mining industry as benchmarks for performance but does not have a standardized meaning and is disclosed 
in addition to IFRS measures.   

The following table provides a reconciliation of C1 cash cost of gold produced per ounce and AISC of gold produced

Earnings before interest, taxes, depreciation, and amortization (“EBITDA”) and Adjusted EBITDA 

EBITDA  represents  earnings  before  interest  expense,  income  taxes,  depreciation,  and  amortization.  Adjusted 
EBITDA includes further adjustments for non-recurring items and/or items not indicative to the future operating 
performance of the Company.  The Company believes EBITDA and adjusted EBITDA are appropriate supplemental 
measures of debt service capacity and performance of its operations. 

Adjusted EBITDA is calculated by removing the following income statement items: 

-  Recovery of valued added taxes 
- 
Foreign exchange loss (gain) 
- 
Loss on gold hedge contracts 
- 
Share based compensation 
- 
Incremental costs in response to COVID-19 pandemic 
- 
Loss on debt settlement 

Note: In Q4 2020 and Fiscal 2020, incremental costs in response to COVID-19 pandemic is included as an adjustment to the calculation of Adjusted EBITDA. 
In Q4 2020 and Fiscal 2020, recovery of value added taxes was not included as an adjustment to the calculation of Adjusted EBITDA. 

Adjusted  net  income  attributable  to  owners  of  the  Company  and  Adjusted  net  income  per  share 
attributable to owners of the Company 

The  Company  uses  the  financial  measure  “Adjusted  net  income  attributable  to  owners  of  the  Company”  and 
“Adjusted  net  income  per  share  attributable  to  owners  of  the  Company”  (“Adjusted  EPS”)  to  supplement 
information  in  its  consolidated  financial  statements.    The  Company  believes  that,  in  addition  to  conventional 
measures prepared in accordance with IFRS, the Company and certain investor and analysts use this information 
to evaluate the Company’s performance.  The Company excludes the following items from net income to provide 
a  measure  which  allows  the  Company  and  investors  to  evaluate  the  operating  results  of  the  underlying  core 
operations: i) net recovery of value added taxes, ii) share based compensation, iii) unrealized foreign exchange 
loss (gain) on USD denominated debt in MCSA, iv) unrealized loss (gain) on foreign exchange derivative contracts, 
net  of  tax,  v)  incremental  costs  in  response  to  COVID-19  pandemic,  vi)  unrealized  loss  (gain)  on  interest  rate 
derivative  contracts,  vii)  loss  on  debt  settlement,  and  viii)  unrealized  loss  on  gold  hedge  contracts.  The 
presentation of Adjusted EPS is not meant to substitute the net income (loss) per share attributable to owners of 
the Company (“EPS”) presented in accordance with IFRS, but rather it should be evaluated in conjunction with 
such IFRS measures. 

The following table provides a detailed reconciliation of net income (loss) attributable to owners of the Company 
as reported in the Company’s consolidated financial statements to adjusted net income attributable to owners of 
the Company and Adjusted EPS.

Net Debt 

Net debt is determined based on cash and cash equivalents, restricted cash and loans and borrowings as reported 
in the Company’s consolidated financial statements. The Company uses net debt as a measure of the Company’s 
ability to pay down its debt.  The following table provides a calculation of net debt based on amounts presented 
in the Company’s consolidated financial statements as at December 31, 2020, September 30, 2020, and December 
31, 2019. 

Working Capital (Deficit) and Available Liquidity 

Working  capital  is  determined  based  on  current  assets  and  current  liabilities  as  reported  in  the  Company’s 
consolidated financial statements. The Company uses working capital as a measure of the Company’s short-term 
financial health and operating efficiency.  Available liquidity includes the Company’s working capital and undrawn 
revolving credit facilities in place. The following table provides a calculation for these based on amounts presented

Disclosure Controls and Procedures and Internal Control over Financial Reporting 

The  Company’s  management,  with  the  participation  of  the  CEO  and  CFO,  is  responsible  for  establishing  and 
maintaining adequate disclosure controls and procedures (“DC&P”) and internal control over financial reporting 
(“ICFR”).  

The  Company’s  DC&P  are  designed  to  provide  reasonable  assurance  that  material  information  related  to  the 
Company is identified and communicated on a timely basis.  

The Company’s ICFR is a process designed to provide reasonable assurance regarding the reliability of financial 
reporting and the preparation of financial statements for external purposes in accordance with IFRS.  Any system 
of ICFR, no matter how well designed, has inherent limitations and cannot provide absolute assurance that all 
misstatements  and  instances  of  fraud,  if  any,  within  the  Company  have  been  prevented  or  detected.  The 
Company’s ICFR is designed to provide reasonable assurance regarding the reliability of financial reporting and 
the preparation of financial statements for external purposes in accordance with IFRS.  

The Company uses the Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring 
Organizations of the Treadway Commission.  

The Company’s management, under the supervision of the CEO and CFO, has evaluated the design and operating 
effectiveness of the Company’s DC&P and ICFR and concluded that the Company’s DC&P and ICFR were effective 
as of December 31, 2020. 

There  were  no  changes  in  the  Company’s  DC&P  and  ICFR  that  materially  affected,  or  are  reasonably  likely  to 
materially affect, ICFR during Q4 2020.

Forward-looking  information  includes  statements  that  use  forward-looking  terminology  such  as  “may”,  “could”, 
“would”,  “will”,  “should”,  “intend”,  “target”,  “plan”,  “expect”,  “budget”,  “estimate”,  “forecast”,  “schedule”, 
“anticipate”,  “believe”,  “continue”,  “potential”,  “view”  or  the  negative  or  grammatical  variation  thereof  or  other 
variations  thereof  or  comparable  terminology.  Such  forward-looking  information  includes,  without  limitation, 
statements with respect to mineral reserve and mineral resource estimates as well as LOM plans; targeting additional 
mineral resources and expansion of deposits; the Company’s expectations, strategies and plans for the MCSA Mining

development  and  production  activities;  the  significance  of  any  particular  exploration  program  or  result  and  the 
Company’s  expectations  for  current  and  future  exploration  plans  including,  but  not  limited  to,  planned  areas  of 
additional exploration, the significance of any drill results or new discoveries and targets, including without limitation, 
extensions of defined mineralized zones, possibilities for mine life extensions or continuity of high-grade mineralization, 
the recoverable value of any metals other than copper, further extensions and expansion of mineralization near  the 
Company’s existing operations and throughout the Curaçá Valley or the NX Gold Mine, the timing and advancement of 
ongoing projects including the Deepening Extension Project and the re-start of the Surubim open pit mine; estimated 
completion  dates  for  certain  milestones;  successfully  adding  or  upgrading  mineral  resources  and  successfully 
developing new deposits; the costs and timing of future exploration and development including but not limited to the 
Deepening Extension Project at the MCSA Mining Complex; the significance of any potential optimization initiatives in 
connection with the Boa Esperança Property and the potential issuance, and timing of, an OFS; the impact of the COVID-
19 pandemic on the Company’s planned drill programs; the timing and amount of future production at the MCSA Mining 
Complex and the NX Gold Property; the representativeness of the material tested in the Company’s ore sorting trial 
campaign to actual results of each of the mines tested during the campaign and the potential benefits of ore sorting in 
the LOM plans at any of the Company's operations including the Vermelhos District as well as any potential savings on 
transport  costs,  any  potential  reduction  in  water,  diesel  and  electricity  use,  as  well  as  any  proposed  reductions  in 
flotation tailings as a result of ore sorting implementation, which may or may not occur in any capacity at the Company's 
operations  or  life-of-mine  plans  now  or  in  the  future,  the  Company's  ability  to  service  its  ongoing  obligations,  the 
Company's  future  production  outlook,  cash  costs,  capital  resources,  expenditures,  the  impact  of  new  accounting 
standards and amendments on the Company's financial statements, and current global macroeconomic uncertainty 
stemming  from  the  COVID-19  pandemic  and  its  impact  on  the  Company’s  business,  financial  condition,  results  of 
operations, cash flows and prospects. 

Forward-looking information is not a guarantee of future performance and is based upon a number of estimates and 
assumptions of management in light of management’s experience and perception of trends, current conditions and 
expected  developments,  as  well  as  other  factors  that  management  believes  to  be  relevant  and  reasonable  in  the 
circumstances, as of the date of this MD&A including, without limitation, assumptions about: continued effectiveness 
of the measures taken by the Company to mitigate the possible impact of COVID-19 on its workforce and operations; 
favourable equity and debt capital markets; the ability to raise any necessary additional capital on reasonable terms to

exchange rates and interest rates; operating conditions being favourable such that the Company is able to operate in a 
safe,  efficient  and  effective  manner;  work  force  conditions  to  remain  healthy  in  the  face  of  prevailing  epidemics, 
pandemics or other health risks (including COVID-19), political and regulatory stability; the receipt of governmental, 
regulatory and third party approvals, licenses and permits on favourable terms; obtaining required renewals for existing 
approvals, licenses and permits on favourable terms; requirements under applicable laws; sustained labour stability; 
stability  in  financial  and  capital  goods  markets;  availability  of  equipment  and  critical  supplies,  spare  parts  and 
consumables;  positive  relations  with  local  groups  and  the  Company’s  ability  to  meet  its  obligations  under  its 
agreements with such groups; and satisfying the terms and conditions of the Company’s current loan arrangements. 
While the Company considers these assumptions to be reasonable, the assumptions are inherently subject to significant 
business,  social,  economic,  political,  regulatory,  competitive,  global  health,  and  other  risks  and  uncertainties, 
contingencies  and  other  factors  that  could  cause  actual  actions,  events,  conditions,  results,  performance  or 
achievements to be materially different from those projected in the forward-looking information. Many assumptions 
are based on factors and events that are not within the control of the Company and there is no assurance they will 
prove to be correct. 

Furthermore, such forward-looking information involves a variety of known and unknown risks, uncertainties and other 
factors which may cause the actual plans, intentions, activities, results, performance or achievements of the Company 
to be materially different from any future plans, intentions, activities, results, performance or achievements expressed 
or implied by such forward-looking information. Such risks include, without limitation the risk factors listed under the 
heading “Risk Factors” in the AIF.    

Although the Company has attempted to identify important factors that could cause actual actions, events, conditions, 
results, performance or achievements to differ materially from those described in forward-looking information, there 
may be other factors that cause actions, events, conditions, results, performance or achievements to differ from those 
anticipated, estimated or intended. 

The Company cautions that the foregoing lists of important assumptions and factors are not exhaustive. Other events 
or circumstances could cause actual results to differ materially from those estimated or projected and expressed in, or 
implied  by,  the  forward-looking  information  contained  herein.  There  can  be  no  assurance  that  forward-looking 
information will prove to be accurate, as actual results and future events could differ materially from those anticipated 
in such information. Accordingly, readers should not place undue reliance on forward-looking information. 

Forward-looking information contained herein is made as of the date of this MD&A and the Company disclaims any 
obligation to update or revise any forward-looking information, whether as a result of new information, future events 
or results or otherwise, except as and to the extent required by applicable securities laws. 

Cautionary Notes Regarding Mineral Resource and Reserve Estimates  

In accordance with applicable Canadian securities regulatory requirements, all mineral reserve and mineral resource 
estimates of the Company disclosed or incorporated by reference in this MD&A have been prepared in accordance with 
NI 43-101 and are classified in accordance with the Canadian Institute of Mining, Metallurgy and Petroleum (“CIM”) 
Definition Standards for Mineral Resources and Mineral Reserves, adopted by the CIM Council on May 10, 2014 (the 
“CIM Standards”). 

Mineral resources which are not mineral reserves do not have demonstrated economic viability. Pursuant to the CIM 
Standards, mineral resources have a higher degree of uncertainty than mineral reserves as to their existence as well as 
their economic and legal feasibility. Inferred mineral resources, when compared with Measured or Indicated mineral 
resources, have the least certainty as to their existence, and it cannot be assumed that all or any part of an Inferred 
mineral resource will be upgraded to an Indicated or Measured mineral resource as a result of continued exploration. 
Pursuant to NI 43-101, Inferred mineral resources may not form the basis of any economic analysis. Accordingly, readers 
are cautioned not to  assume that all or any part of a mineral resource exists, will ever be converted into a mineral 
reserve, or is or will ever be economically or legally mineable or recovered.

Key Audit Matters 

Key  audit  matters  are  those  matters  that,  in  our  professional  judgment,  were  of  most 
significance in our audit of the financial statements for the year ended December 31, 2020. 
These matters were addressed in the context of our audit of the financial statements as a 
whole, and in forming our opinion thereon, and we do not provide a separate opinion on 
these matters. 

We  have  determined  the  matter  described  below  to  be  the  key  audit  matter  to  be 
communicated in our auditors’ report. 

Assessment  of  recognition  of  uncertainties  over  income  tax  treatments  in 
Brazil 

Description of the matter 

We draw your attention to Notes 2(d), 3(e) and 11(c)(ii) to the financial statements.  

Uncertainties  over  income  tax  treatments  are  evaluated on  the  basis  of whether  it  is 
probable 
taxing 
authorities.  These uncertainties impact the amount of income taxes recognized. 

they  will  be  accepted  upon  examination  by 

the  relevant 

that 

The Entity operates in Brazil where tax authorities may audit income tax treatments and 
the resolution of such audits may span multiple years. Tax law in Brazil is complex and 
often subject to changes and to varied interpretations; accordingly, the ultimate outcome 
with respect to income tax treatments may differ from the amounts recognized. The Entity’s 
assessment of whether it is probable that uncertain income tax treatments will be accepted 
by tax authorities in Brazil is a significant management judgment. 

Why the matter is a key audit matter 

We identified the assessment of recognition of uncertainties over income tax treatments in 
Brazil  as  a  key  audit  matter.  This  matter  represented  an  area  of  significant  risk  of 
misstatement  given  the  high  degree  of  subjectivity  and  judgment  required  in  evaluating 
management’s significant judgement.  As a result, specialized skills and knowledge were 
required in evaluating management’s significant judgement. 

How the matter was addressed in the audit 

The  primary  procedures  we  performed  to  address  this  key  audit  matter  included  the 
following: 

We  involved  income  tax  and  legal  professionals  in  Brazil  with  specialized  skills  and 
knowledge who assisted in assessing whether it was probable that uncertain income tax 
treatments would be accepted by:   

–  Developing  an 

independent  assessment  based  on  our  understanding  and 

interpretation of tax laws in Brazil

– 

– 

Inspecting correspondence documents with Brazilian tax authorities and evaluating the 
implications of the matters raised by such authorities   

Inspecting opinions provided by the Entity’s tax and legal advisors.  

We also assessed whether it was probable that uncertain income tax treatments would be 
accepted by obtaining legal enquiry letter responses from law firms related to identified tax 
claims and contingencies. 

Other Information 

Management is responsible for the other information. Other information comprises: 

– 

– 

the  information  included  in  Management’s  Discussion  and  Analysis  filed  with  the 
relevant Canadian Securities Commissions; and 

information,  other  than  the  financial  statements  and  the  auditors’  report  thereon, 
included in a document likely to be entitled “Annual Report”. 

Our opinion on the financial statements does not cover the other information and we do 
not and will not express any form of assurance conclusion thereon.  

In connection with our audit of the financial statements, our  responsibility is to read the 
other information identified above and, in doing so, consider whether the other information 
is materially inconsistent with the financial statements or our knowledge obtained in the 
audit and remain alert for indications that the other information appears to be materially 
misstated. 

We obtained the information included in Management’s Discussion and Analysis filed with 
the relevant Canadian Securities Commissions as at the date of this auditors’ report.   If, 
based on the work we have performed on this other information, we conclude that there is 
a material misstatement of this other information, we are required to report that fact in the 
auditors’ report.  We have nothing to report in this regard. 

The  information,  other  than  the  financial  statements  and  the  auditors’  report  thereon, 
included  in  a  document  likely  to  be  entitled  “Annual  Report”  is  expected  to  be  made 
available to us after the date of this auditors’ report.  If, based on the work we will perform 
on this other information, we conclude that there is a material misstatement of this other 
information, we are required to report that fact to those charged with governance.    

Responsibilities  of  Management  and  Those  Charged  with 
Governance for the Financial Statements 

Management  is  responsible  for  the  preparation  and  fair  presentation  of  the  financial 
statements in accordance with International Financial Reporting Standards, and for such 
internal  control  as  management  determines  is  necessary  to  enable  the  preparation  of 
financial statements that are free from material misstatement, whether due to fraud or error. 

In preparing the financial statements, management is responsible for assessing the Entity’s 
ability to continue as a going concern, disclosing as applicable, matters related to going 
concern  and  using  the  going  concern  basis  of  accounting  unless  management  either 

E R O   C O P P E R  |     2 0 2 0   A N N U A L   R E V I E W     |   4 7  

 
 
 
 
 
 
 
 
 
 
intends to liquidate the Entity or to cease operations, or has no realistic alternative but to 
do so. 

Those  charged  with  governance  are  responsible  for  overseeing  the  Entity‘s  financial 
reporting process.  

Auditors’  Responsibilities  for  the  Audit  of  the  Financial 
Statements 

Our objectives are to obtain reasonable assurance about whether the financial statements 
as a whole are free from material misstatement, whether due to fraud or error, and to issue 
an auditors’ report that includes our opinion.  

Reasonable assurance is a high level of assurance, but is not a guarantee that an audit 
conducted in accordance with Canadian generally accepted auditing standards will always 
detect a material misstatement when it exists.  

Misstatements can arise from fraud or error and are considered material if, individually or 
in the aggregate, they could reasonably be expected to influence the economic decisions 
of users taken on the basis of the financial statements. 

As part of an audit in accordance with Canadian generally accepted auditing standards, 
we exercise professional judgment and maintain professional skepticism throughout the 
audit.  

We also: 

– 

Identify  and  assess  the  risks  of  material  misstatement  of  the  financial  statements, 
whether due to fraud or error, design and perform audit procedures responsive to those 
risks, and obtain audit evidence that is sufficient and appropriate to provide a basis for 
our opinion.  

The risk of not detecting a material misstatement resulting from fraud is higher than for 
one resulting from error, as fraud may involve collusion, forgery, intentional omissions, 
misrepresentations, or the override of internal control. 

–  Obtain an understanding of internal control relevant to the audit in order to design audit 
procedures  that  are  appropriate  in  the  circumstances,  but  not  for  the  purpose  of 
expressing an opinion on the effectiveness of the Entity's internal control.  

–  Evaluate the appropriateness of accounting policies used and the reasonableness of 

accounting estimates and related disclosures made by management. 

–  Conclude on the appropriateness of management's use of the going concern basis of 
accounting and, based on the audit evidence obtained, whether a material uncertainty 
exists related  to  events or  conditions  that  may cast significant  doubt  on  the  Entity's 
ability to continue as a going concern. If we conclude that a material uncertainty exists, 
we are required to draw attention in our auditors’ report to the related disclosures in 
the financial statements or, if such disclosures are inadequate, to modify our opinion. 
Our  conclusions  are  based  on  the  audit  evidence  obtained  up  to  the  date  of  our 
auditors’ report. However, future events or conditions may cause the Entity to cease to 
continue as a going concern.

–  Evaluate  the  overall  presentation,  structure  and  content  of  the  financial  statements, 
including  the  disclosures,  and  whether  the  financial  statements  represents  the 
underlying transactions and events in a manner that achieves fair presentation. 

–  Communicate with those charged with governance regarding, among other matters, 
the planned scope and timing of the audit and significant audit findings, including any 
significant deficiencies in internal control that we identify during our audit.  

–  Provide those charged with governance with a statement that we have complied with 
relevant ethical requirements regarding independence, and communicate with them all 
relationships  and  other  matters  that  may  reasonably  be  thought  to  bear  on  our 
independence, and where applicable, related safeguards. 

–  Obtain sufficient appropriate audit evidence regarding the financial information of the 
entities  or  business  activities  within  the  group  Entity  to  express  an  opinion  on  the 
financial  statements.  We  are  responsible 
the  direction,  supervision  and 
performance of the group audit. We remain solely responsible for our audit opinion.

Notes to Consolidated Financial Statements 
(Tabular amounts in thousands of US Dollars, except share and per share amounts) 

1.  Nature of Operations  

Ero Copper Corp. (“Ero" or the "Company") was incorporated on May 16, 2016 under the Business Corporations 
Act (British Columbia) and maintains its head office at Suite 1050, 625 Howe Street, Vancouver, BC, V6C 2T6.  
The Company’s shares are publicly traded on the Toronto Stock Exchange under the symbol “ERO”. 

The Company’s principal asset is its 99.6% ownership interest in Mineração Caraíba S.A. (“MCSA”).  The Company 
also currently owns a 97.6% ownership interest in NX Gold S.A. (“NX Gold”) indirectly through its wholly-owned 
subsidiary, Ero Gold Corp. (“Ero Gold”).   

MCSA is a Brazilian company which holds a 100% interest in the MCSA Mining Complex and the Boa Esperança 
Property (Note 7).  MCSA’s predominant activity is the production and sale of copper concentrate from the MCSA 
Mining Complex, located in Bahia, Brazil, with gold and silver produced and sold as by-products. The Company 
currently mines copper ore from the Pilar underground mine (“Pilar UG Mine”) and the Vermelhos underground 
mine (“Vermelhos UG Mine”).  The Boa Esperança Property is located within the municipality of Tucumã in the 
southeastern part of the state of Pará, Brazil, and consists of a single mineral concession covering an area of 
4,034 hectares (“ha”).   

NX Gold is a Brazilian gold mining company focused on the exploration and commercialization of gold as its main 
product  and  silver  as  its  by-product.    NX  Gold  wholly  owns  a  31,096  ha  property,  located  approximately  18 
kilometers west of the town of Nova Xavantina, in southeastern Mato Grosso State, Brazil, consisting of a single 
mining concession covering an area of 620 ha, where all gold mining and processing activities occur.    

On  March  11,  2020,  the  COVID-19  outbreak  was  declared  a  pandemic  by  the  World  Health  Organization. 
Although COVID-19 has not materially impacted the Company’s operations during the year ended December 31, 
2020, the situation is dynamic and the ultimate duration and magnitude of the impact on the economy and our 
business are not known at this time. These impacts could include an impact on the Company’s ability to obtain 
debt and equity financing, impairment of investments, impairments in the value of long-lived assets, continued 
fluctuation  in  the  value  of  the  Brazilian  Real  or  potential  future  decreases  in  revenue  or  the  profitability  of 
ongoing operations.   

2.  Basis of Preparation 

a)  Statement of Compliance 

These  consolidated  financial  statements  have  been  prepared  in  accordance  with  International  Financial 
Reporting  Standards  (“IFRS”)  as  issued  by  the  International  Accounting  Standards  Board  (“IASB”)  and 
interpretations of the International Financial Reporting Interpretations Committee. 

These consolidated financial statements were authorized for issue by the Board of Directors of the Company 
(the “Board”) on March 16, 2021. 

b)  Basis of Presentation and Principles of Consolidation 

These consolidated financial statements have been prepared on a historical cost basis except for fair-value 
through-profit-or-loss and derivative financial instruments, which are measured at fair value. 

These  consolidated  financial  statements  include  the  accounts  of  the  Company  and  its  subsidiaries.  
Subsidiaries are entities controlled by the Company.  Control over a subsidiary is defined to exist when the 
Company is exposed to variable returns from involvement with an investee and has the ability to affect the 
returns through power over the investee.  All intercompany balances and transactions are eliminated upon 
consolidation.

Ero Copper Corp. 
Notes to Consolidated Financial Statements 
(Tabular amounts in thousands of US Dollars, except share and per share amounts) 

The  Company  applies  the  acquisition  method  to  account  for  business  combinations.  The  consideration 
transferred by the Company to obtain control of a subsidiary is calculated as the sum of the acquisition-date 
fair values of assets transferred, liabilities assumed and the equity interests issued by the Company, which 
includes  the  fair  value  of  any  asset  or  liability  arising  from  a  contingent  consideration  arrangement. 
Acquisition costs are expensed as incurred. 

The  Company  recognizes  identifiable  assets  acquired  and  liabilities  assumed  in  a  business  combination 
regardless of whether they have been previously recognized in the acquiree’s financial statements prior to 
the acquisition. Assets acquired and liabilities assumed are generally measured at their acquisition-date fair 
values. 

Goodwill arising from acquisitions is the excess of the sum of a) fair value of consideration transferred, b) 
the recognized amount of any non-controlling interest in the acquiree and c) acquisition-date fair value of 
any existing equity interest in the acquiree, over the acquisition-date fair values of identifiable net assets. If 
the  fair  values  of  identifiable  net  assets  exceed  the  sum  calculated  above,  the  excess  amount  would  be 
recognized in profit or loss immediately.   

Since the Company does not own 100% of its interests in MCSA and NX Gold, the  interest attributable to 
non-controlling  shareholders  is  reflected  in  non-controlling  interests.    Adjustments  to  non-controlling 
interests that do not involve the loss of control are accounted for as equity transactions and adjustments are 
based on a proportionate amount of the net assets of the subsidiary.   

c)  Foreign Currency Translation 

The functional currency and presentation currency of the Company is the US dollar. The monetary assets and 
liabilities of the Company that are denominated in foreign currencies are translated at the rate of exchange 
at  the  statement  of  financial  position  date  while  non-monetary  assets  and  liabilities  are  translated  at 
historical rates.  Revenues and expenses are translated at the exchange rates approximating those in effect 
on the date of the transactions.  Exchange gains and losses arising on translation are included in profit or 
loss.   

The functional currency of MCSA and NX Gold is the Brazilian Real (“BRL”).  The assets and liabilities of MCSA 
and  NX  Gold  are  translated  into  the  US  dollar  presentation  currency  using  the  rate  of  exchange  at  the 
statement  of  financial  position  date  while  revenues  and  expenses  are  translated  at  the  exchange  rates 
approximating  those  in  effect  on  the  date  of  the  transactions.    Exchange  gains  and  losses  arising  on 
translation are included in a separate component of shareholders’ equity. 

d)  Use of Estimates and Judgments  

In preparing these financial statements, management has made judgments, estimates and assumptions that 
affect  the  application  of  the  Company’s  accounting  policies  and  the  reported  amounts  of  the  assets, 
liabilities, revenues and expenses.  Actual results may differ from these estimates.   

The estimates and assumptions are reviewed on an ongoing basis.  Revisions to estimates are recognized 
prospectively. 

Critical Judgments  

Functional currency 

The functional currency of the Company and each of its subsidiaries is the currency of the primary economic 
environment in which the entities operate.  The Company has determined that the functional currency for 
the  Company  is  the  US  dollar  while  the  functional  currency  for  MCSA  and  NX  Gold  is  the  Brazilian  Real.

Ero Copper Corp. 
Notes to Consolidated Financial Statements 
(Tabular amounts in thousands of US Dollars, except share and per share amounts) 

Assessment  of  functional  currency  involves  certain  judgements  to  determine  the  primary  economic 
environment and the Company reconsiders the functional currency of its entities if there is a change in events 
and conditions which determined the primary economic environment. 

Legal claims and contingent liabilities 

The recognition of legal provisions and contingent liabilities involves the assessment of claims made against 
the Company and each of its subsidiaries.  The recognition of a legal provision, or disclosure of a contingent 
liability, involves certain judgements to determine the probability of whether a cash outflow will occur.  In 
making this judgment, management has assessed various criteria and also relies on the opinions of its legal 
advisers to assist in making this assessment. 

Key Sources of Estimation Uncertainty  

The preparation of financial statements in conformity with IFRS requires management to make estimates 
and assumptions that affect the reported amounts of assets and liabilities and the disclosure of assets and 
liabilities at the date of the consolidated financial statements and the reported amounts of expenses during 
the  reporting  periods.  Actual  results  could  differ  from  those  estimates  and  such  differences  could  be 
significant.  Significant  estimates  made  by  management  affecting  the  consolidated  financial  statements 
include:  

Derivative instruments 

The fair value of derivative instruments is determined using either present value techniques or option pricing 
models  that  utilize  a  variety of  inputs  that  are  a  combination  of  quoted  prices  and  market-corroborated 
inputs, including assumptions for forward interest and foreign exchange rates, volatilities and discount rates.  
The fair  value of the Company’s derivative contracts includes an adjustment  for credit  risk for either the 
Company or the counter party as applicable.  Changes in the assumptions for inputs into the models affect 
the fair value of the derivatives recognized in the statement of financial position as well as the unrealized 
gains or losses recognized in net income.   

Mineral reserve and resource estimates including life of mine plan 

The  Company  estimates  its  mineral  reserves  and  mineral  resources  based  on  information  compiled  by 
competent individuals.  Mineral reserves are used in the calculation of depreciation, impairment assessments 
and for forecasting the timing of payment of mine closure and rehabilitation costs. 

There are numerous uncertainties inherent in estimating mineral reserves, and assumptions that are valid at 
the time of estimation may change significantly when new information becomes available.  Changes in the 
estimation methodology,  forecasted prices of commodities, exchange rates, production costs or recovery 
rates  may  change  the  economic  status  of  mineral  reserves  and  may,  ultimately,  result  in  changes  in  the 
mineral reserves. 

The carrying amounts of the Company’s mineral, property, plant and equipment are depleted in part based 
on recoverable mineral reserve tonnes processed, depending on the use of the asset.  Changes to estimates 
of recoverable quantities of metals, mineral reserve tonnes and depletable costs, including changes resulting 
from revisions to the Company’s mine plans and changes in metals prices forecasts, can result in a change to 
future depreciation and depletion rates and may result in impairment charges.

Mine closure and rehabilitation costs 

Significant  estimates  and  assumptions  are  made  in  determining  the  provision  for  mine  closure  and 
rehabilitation  as  there  are  numerous  factors  that  will  affect  the  ultimate  liability  payable.    These  factors 
include estimation of the extent and cost of rehabilitation activities, timing of future cash flows, discount 
rates, inflation rate, and regulatory requirements. 

Changes in the above factors can result in a change to the provision recognized by the Company.  Changes 
to mine closure and rehabilitation costs are recorded with a corresponding change to the carrying amounts 
of related mineral, property, plant and equipment.  Adjustments to the carrying amounts of related mineral, 
property, plant and equipment can result in a change to future depreciation and depletion expense. 

Significant assumptions used to determine mine closure and rehabilitation costs are included in Note 11(a). 

Income taxes 

The  determination  of  the  Company’s  tax  expense  for  the  period  and  deferred  tax  assets  and  liabilities 
involves significant estimation and judgement by management. In determining these amounts, management 
interprets  tax  legislation  in  a  variety  of  jurisdictions  and  makes  estimates  of  the  expected  timing  of  the 
reversal of deferred tax assets and liabilities. Management also makes estimates of future earnings, which 
affect the extent to which potential future tax benefits may be used. The Company is subject to assessments 
by various taxation authorities, which may interpret legislation differently. These differences may affect the 
final amount or the timing of the payment of taxes. The Company provides for such differences where known 
based on management’s best estimate of the probable outcome of these matters. 

The Company operates in Brazil where tax authorities may audit income tax treatments and the resolution 
of such audits may span multiple years. Tax law in Brazil is complex and often subject to changes and to 
varied interpretations; accordingly, the ultimate outcome with respect to income tax treatments may differ 
from the amounts recognized. The Company’s assessment of whether it is probable that uncertain income 
tax treatments will be accepted by tax authorities in Brazil is a significant management judgment. 

e) New Accounting Standards and Interpretations Adopted in the Year

The following new and amended IFRS pronouncements were adopted effective January 1, 2020 and had no
impact to the Company’s financial statements:

•

•

Amendments to References to the Conceptual Framework in IFRS Standards

In September  2019, the IASB issued first  phase amendments IFRS 9 Financial Instruments, IAS 39
Financial  Instruments:  Recognition  and  Hedging  and  IFRS  7  Financial  Instrument  Disclosures  to
address  the  financial  reporting  impact  of  the  reform  on  interest  rate  benchmarks,  such  as  the
discontinuance of the interbank offered rates. The first phase amendment is focused on the impact
to hedge accounting requirements. The Company adopted the first phase amendment and there was
no material impact on its consolidated financial statements.  The Company will continue to assess
the effect of amendments related to the interest rate benchmark reform on its consolidated financial
statements.

The  following  amendment  to  accounting  standards has  been  issued  but  not  yet  adopted  in  the  financial 
statements: 

• On  May  14,  2020,  the  IASB  published  a  narrow  scope  amendment  to  IAS  16  Property,  Plant  and
Equipment  - Proceeds before Intended Use. The amendment  prohibits deducting from the cost of
property, plant and equipment amounts received from selling items produced while preparing the
asset for its intended use. Instead, amounts received will be recognized as sales proceeds and related

cost in profit or loss. The effective date is for annual periods beginning on or after January 1, 2022. 
The  Company  does  not  expect  to  adopt  this  amendment  until  the  effective  date,  and  does  not 
anticipate a material impact on its consolidated financial statements. 

3. Significant Accounting Policies

a) Revenue

Revenue  is  generated  from  the  sale  of  sale  of  metals  in  concentrate  and  gold  doré.  The  Company’s
performance obligations relate primarily to the delivery of the concentrate or gold doré to customers, with
each shipment representing a separate performance obligation.

Revenue from the sale of metals in concentrate and gold doré is recognized at the point the customer obtains
control of the product. Control is transferred when title has passed to the purchaser, the product is physically
delivered to the customer, the customer controls the risks and rewards of ownership and the Company has
a present right to payment for the product which is generally when the concentrate or ore is delivered to a
location designated by the customer.

The sales amount is typically based on quoted market and contractual prices which are fixed at the time the
shipment  is  received  at  the  customers’  premises.    In  certain  circumstances  the  sales  price  of  metals  in
concentrate may be determined in a period subsequent to the date of sale (provisionally priced sales) based
on the terms of specific copper concentrate contracts.  Provisionally priced sales are recognized based on an
estimate of metal contained using forward market prices corresponding with the expected date that final
sales  prices  will  be  fixed.    The  period  between  provisional  pricing  and  final  settlement  can  be  up  to  one
month.  The settlement receivable is recorded at fair value each reporting period by reference to forward
market  prices  until  the  date of  final  pricing,  with  the  changes  in  fair  value  recorded  as  an  adjustment  to
revenue.

b) Tax Incentives

The Company receives certain tax incentives in Brazil.  These tax incentives are recognized in profit or loss in
the  period  the  incentives  are  received  or  receivable  and  recorded  against  the  expenditure  that  they  are
intended to compensate.

c) Finance Income and Finance Expense

Finance income includes interest on cash and cash equivalents, restricted cash and financial investments,
and gains related to changes in the fair value of financial assets measured at fair value through profit or loss.
Interest income is recognized as it accrues in profit or loss, using the effective interest method.

Finance  expense  comprise  interest  expense  on  loans  and  borrowings,  unwinding  of  the  discount  on
provisions and leases, commitment fees and  losses related to changes in the fair value of financial assets
measured  at  fair  value  through  profit  or  loss.  Borrowing  costs  that  are  not  directly  attributable  to  the
acquisition, construction or production of a qualifying asset are recognized in profit or loss using the effective
interest method.

d) Employee Benefits

Short-term employee benefit obligations are recognized as personnel expenses as the corresponding service
is provided. Liabilities are recognized at the amount that is expected to be paid if the Company has a present
legal or constructive obligation to pay that amount based on past services rendered by the employee, and
the obligation can be estimated reliably.  There are no long-term employee benefit plans.

Notes to Consolidated Financial Statements 
(Tabular amounts in thousands of US Dollars, except share and per share amounts) 

e) Taxation

Income tax expense comprises current and deferred tax.  Current income tax is the expected tax payable or
receivable on the taxable income or loss for the year using tax rates enacted or substantively enacted at the
reporting date.

Deferred  income  tax  is  recognized  in  respect  of  temporary  differences  between  the  carrying  amounts  of
assets and liabilities for financial reporting purposes and the amounts used for taxation purposes.  Deferred
income tax is measured at the tax rates that are expected to be applied to temporary differences when they
reverse,  based  on  the  tax  laws  that  have  been  enacted  or  substantively  enacted  at  the  reporting  date.
Deferred income tax assets and liabilities are offset if there is a legally enforceable right to offset current tax
liabilities and assets, and they relate to income taxes levied by the same tax authority on the same taxable
entity.   Deferred income tax is not recognized for the initial recognition of assets or liabilities in a transaction
that is not a business combination and that effects neither accounting nor taxable income or loss, differences
related  to  investments  in  subsidiaries  to  the  extent  that  it  is  probable  that  they  will  not  reverse  in  the
foreseeable future and taxable differences arising from the initial recognition of goodwill.

A  deferred  income  tax  asset  is  recognized  for  unused  tax  losses,  tax  credits  and  deductible  temporary
differences, to the extent that it is probable that future taxable profits will be available against which they
can be utilized.  Deferred income tax assets are reviewed at each reporting date and are reduced to the
extent that it is no longer probable that the related tax benefit will be realized.

Uncertainties over income tax treatments are evaluated on the basis of whether it is probable that they will
be accepted upon examination by the relevant taxing authorities in Brazil.  These uncertainties impact the
amount  of  income  taxes  recognized.  If  it  is  determined  that  an  uncertain  income  tax  treatment  is  not
probable  of  being  accepted,  the  effect  of  the  uncertain  income  tax  treatment  is  reflected  in  the
determination  of  income  taxes  based  the  most  likely  amount  or,  if  there  are  a  wide  range  of  possible
outcomes, the expected value.

f)

Inventories

Inventories are measured at the lower of cost and net realizable value. The cost of consumable inventory is
determined on a weighted average acquisition cost basis.  Cost of stockpile inventory, products in progress
and finished goods is determined based on a weighted average production cost basis and includes the cost
of mining and processing ore including direct labour and materials; depreciation and amortization; and an
appropriate share of production overheads based on normal operating capacity.

Net realizable value of stockpile inventory, products in progress and finished goods is the estimated selling
price in the ordinary course of business, less estimated completion costs and selling expenses.

Provisions for low turnover or obsolete supplies and consumables inventory are established by management
as deemed necessary.

g) Mineral, Property, Plant and Equipment

Mineral, property, plant and equipment is measured at acquisition or construction cost, including capitalized
borrowing costs, less accumulated depreciation and accumulated impairment losses.

i) Acquisition and disposal

The cost of mineral, property, plant and equipment include expenditures directly attributable to an asset’s 
acquisition. The cost of assets constructed by Company includes the cost of materials and direct labor, any 

E R O   C O P P E R  |

2 0 2 0   A N N U A L   R E V I E W |   5 9

Ero Copper Corp. 
Notes to Consolidated Financial Statements 
(Tabular amounts in thousands of US Dollars, except share and per share amounts) 

other costs to bring the asset in the place and conditions required to be operated in the manner intended by 
management, costs of disassembly and restoration of the site and borrowing costs on qualifying assets. 

When parts of mineral, property, plant and equipment have different useful lives, they are accounted for as 
separate items (major components) of mineral, property, plant and equipment. 

Gains and losses on disposal of mineral, property, plant and equipment are determined by comparing the 
proceeds from disposal with the carrying amount of equipment and are recognized net within other income.  

ii) Subsequent costs

The cost of replacing plant and equipment is recognized in the carrying amount of the item if it is probable 
that the future economic benefits embodied within the item will flow to the Company and its cost can be 
measured reliably.  The carrying amount of the replaced item is derecognized.  The costs of the day-to-day 
servicing of equipment are included in profit or loss.   

iii) Development and construction-in-progress

When  economically  viable  mineral  reserves  have  been  determined  and  the  decision  to  proceed  with 
development has been approved, exploration and evaluation assets are first assessed for impairment, then 
reclassified to construction-in-progress or mineral properties. The expenditures related to development and 
construction are capitalized as construction-in-progress and are included within mineral, property, plant and 
equipment. Costs associated with the commissioning of new assets incurred before they are operating in the 
way intended by management, including directly attributable costs of testing, are capitalized. Construction-
in-progress includes the purchase price and any costs directly attributable to bringing the asset to the location 
and condition necessary for its intended use including advances on long-lead items.  Construction-in-progress 
is not depreciated.   

Once  the  asset  is  operating  in  the  way  intended  by  management,  construction-in-progress  costs  are 
reclassified to mineral properties or plant and equipment.  

Pre-production  costs  of  removing  overburden  to  access  ore  in  the  open  pit  mines  and  developing  access 
headings  in  the  underground  mines  are  capitalized  as  pre-production  stripping  or  development  costs 
respectively and are included within mineral, property, plant and equipment. Revenues earned during pre-
production periods are also capitalized.  

iv) Mineral properties

Mineral properties consist of the cost of acquiring and developing mineral properties.  Once in production, 
mineral properties are amortized on a units-of-production basis over the component of the ore body to which 
they relate. 

v) Stripping costs and development in the production phase

Where  open  pit  production  stripping  or  underground  development  activities  do  not  result  in  inventory 
produced, but does provide improved access to the ore body, the costs are classified as mineral properties 
when these activities meet all of the following criteria: (1) it is probable that the future economic benefit 
associated with the activity will flow to the Company; (2) the Company can estimate the mineral reserve of 
the ore body for which access has been improved; and (3) the costs relating to the activity associated with 
that mineral reserve can be measured reliably.  

For underground mines, costs incurred to access a mineral reserve of the ore body are capitalized to mineral 
properties or construction-in-progress and are depreciated on a units-of-production basis over the expected

Ero Copper Corp. 
Notes to Consolidated Financial Statements 
(Tabular amounts in thousands of US Dollars, except share and per share amounts) 

useful life of the identified mineral reserve of the ore body to which access has been improved as a result of 
the  development  activity.    For  open  pit  mines,  stripping  costs  are  capitalized  to  mineral  properties  or 
construction-in-progress  until  an  average  stripping  ratio  is  achieved  (waste/ore)  for  the  mine.    After  the 
stripping ratio is achieved, all stripping costs are classified as production costs.  The capitalized stripping costs 
are depreciated over the related mineral reserves accessed by the stripping activity. 

vi)  Mine closure and rehabilitation costs 

The  Company’s  provision  for  mine  closure  and  rehabilitation  liabilities  represents  management’s  best 
estimate  of  the  present  value  of  the  future  cash  outflows  required  to  settle  estimated  reclamation  and 
closure costs at the end of a mine’s life. The provision reflects estimates of future costs, inflation, movements 
in  foreign  exchange  rates  and  assumptions  of  risks  associated  with  the  future  cash  outflows,  and  the 
applicable risk-free interest rates for discounting the future cash outflows. Changes in the above factors can 
result in a change to the provision recognized by the Company. 

vii) Depreciation 

Items  of mineral, property, plant  and equipment  are depreciated on a straight-line method based on the 
estimated economic useful life of each component as follows: 

Buildings 
Mining equipment 
Mobile equipment & other assets 
Mineral properties 
Mine closure and rehabilitation costs 

Right of use assets 

Up to 25 years 
4 years 
5 years 
Units of production 
Units of production or 
period until remediation 
Shorter of the term of 
lease and life of asset 

The depletion of mineral, properties and mine closure and rehabilitation costs is determined based on the 
ratio of tons of copper/kg of gold contained in the ore mined and total proven and probable mineral reserve 
tonnes of contained copper/kg of contained gold.   

Depreciation methods, useful lives and residual values are reviewed at each financial year end and adjusted 
if appropriate.   

h)  Exploration and Evaluation Assets 

Exploration and evaluation costs relate to the initial search for a mineral deposit, the cost of acquisition of a 
mineral property interest or exploration rights and the subsequent evaluation to determine the  economic 
potential  of  the  mineral  deposit.  The  exploration  and  evaluation  stage  commences  when  the  Company 
obtains the legal right or license to begin exploration.  Once the legal rights or license is obtained, exploration 
and evaluation expenses are capitalized as exploration and evaluation assets.   Costs incurred prior to the 
Company obtaining the legal rights are expensed. 

When  the  exploration  and  evaluation  of  a  mineral  property  indicates  that  development  of  the  mineral 
property  is  technically  and  commercially  feasible,  the  future  economic  benefits  are  probable,  and  the 
Company has the intention and sufficient resources to complete the development and use or sell the asset, 
the  related  costs  are  transferred  from  exploration  and  evaluation  assets  to  mineral  property,  plant  and 
equipment. 

Management reviews the carrying value of capitalized exploration costs for indicators that the carrying value 
is impaired at least annually and when facts and circumstances suggest that the carrying amount may exceed

Ero Copper Corp. 
Notes to Consolidated Financial Statements 
(Tabular amounts in thousands of US Dollars, except share and per share amounts) 

the  recoverable  amount.  The  review  is  based  on  the  Company’s  intentions  for  further  exploration  and 
development  of the undeveloped property, results of drilling, commodity prices and other economic and 
geological factors. Subsequent recovery of the resulting carrying value depends on successful development 
or sale of the undeveloped project. If a property does not prove viable, all non-recoverable costs associated 
with the project, net of any previous impairment provisions, are written off. 

i) Financial Instruments

Non-derivative financial assets

The  Company  classifies  its  financial  assets  in  the  following  categories:  at  fair  value  through  profit  or  loss
(“FVTPL”),  at  fair  value  through  other  comprehensive  income  (“FVTOCI”)  or  at  amortized  cost.  The
classification depends on the purpose for which the financial assets were acquired.  Management determines
the  classification  of  its  financial  assets  at  initial  recognition.    Measurement  and  classification  of  financial
assets is dependent on the Company’s business model for managing the financial assets and the contractual
cash flow characteristics of the financial asset.  Financial assets are derecognized when they mature or are
sold, and substantially all the risks and rewards of ownership have been transferred.

Fair values

A number of the Company’s accounting policies and disclosures require the measurement of fair values, for
both financial and non-financial assets and liabilities.

When measuring the fair value of an asset or liability, the Company uses observable market data, as much as
possible. Fair values are classified into different levels in a hierarchy based on the inputs used in the valuation
techniques, as follows:

•

•

•

Level 1: quoted prices (without adjustments) in active markets for identical assets or liabilities.

Level 2: inputs other than Level 1 quoted prices, that are observable for the asset or liability, either
directly (i.e. as prices) or indirectly (i.e. derived from prices).

Level 3: inputs, for assets or liabilities, that are not based on observable market information (non-
observable inputs).

The Company recognizes transfers between levels of the hierarchy of fair value at the end of the reporting 
period during which the change occurred. 

When applicable, additional information on the assumptions used in the fair value calculations are disclosed 
in the specific notes of the corresponding asset or liability.   

Financial assets at FVTPL 

Financial assets carried at FVTPL are initially recorded at fair value and transaction costs are expensed in the 
income statement. Realized and unrealized gains and losses arising from changes in the fair  value of the 
financial asset held at FVTPL are included in profit or loss in the period in which they arise. Derivatives are 
also categorized as FVTPL unless they are designated as hedges. 

Financial assets at FVTOCI 

Investments  in  equity  instruments  at  FVTOCI  are  initially  recognized  at  fair  value  plus  transaction  costs. 
Subsequently  they  are  measured  at  fair  value,  with  gains  and  losses  arising  from  changes  in  fair  value 

E R O   C O P P E R  |

2 0 2 0   A N N U A L   R E V I E W |   6 2

Ero Copper Corp. 
Notes to Consolidated Financial Statements 
(Tabular amounts in thousands of US Dollars, except share and per share amounts) 

recognized in other comprehensive income. Gains or losses on financial assets classified as FVTOCI remain 
within accumulated other comprehensive income following the derecognition of the investment. 

Financial assets at amortized cost 

Financial assets at amortized cost are initially recognized at fair value and subsequently carried at amortized 
cost less any impairment. They are classified as current assets or non-current assets based on their maturity 
date. Gains and losses on derecognition of financial assets classified amortized cost are recognized in profit 
or loss. 

Financial liabilities 

Financial  liabilities  are  recognized  initially  at  fair  value,  net  of  transaction  costs  incurred,  and  are 
subsequently measured at amortized cost. Any difference between the amounts originally received, net of 
transaction costs, and the redemption value is recognized in profit and loss over the period to maturity using 
the effective interest method. 

Derivative instruments  

Derivative instruments, including embedded derivatives in executory contracts or financial liability contracts, 
are classified as at FVTPL and, accordingly, are recorded in the statement of financial position at fair value. 
Unrealized gains and losses on derivatives not designated in a hedging relationship are recorded as part of 
the revenue or expense item to which the derivative relates, depending on the nature of the derivative. Fair 
values for derivative instruments are determined using inputs based on market conditions existing at the 
balance sheet date or settlement date of the derivative. Derivatives embedded in non-derivative contracts 
are recognized separately unless they are closely related to the host contract.   

Trade receivables related to provisionally priced sales are measured at fair value with changes recognized in 
profit or loss. 

Compound instruments 

Equity components of compound instruments, such as convertible debt, are separated from the debt host 
contract  using  the  residual  method.  The  Company  determines  the  fair  value  of  the  debt  component  by 
discounting the expected principal and interest payments using an appropriate discount rate reflective of 
debt instruments with similar risks but without the equity component. The difference between the proceeds 
received and the amount assigned to the debt component is allocated to the equity component. 

Share capital 

Common shares are classified as equity.  Incremental costs directly attributable to the issuance of common 
shares and share options are recognized as a deduction from equity, net of any tax effects. The Company 
includes  the  value  of  share  purchase  warrants  included  in  the  issuance  of  equity  units,  which  consist  of 
common shares and warrants, in share capital. 

Classification and measurement  

The Company has assessed the classification and measurement of its financial assets and financial liabilities 
under IFRS 9 in the following table:  

E R O   C O P P E R  |     2 0 2 0   A N N U A L   R E V I E W     |   6 3

 
 
 
 
 
 
 
 
  
 
 
 
 
 
  
  
Ero Copper Corp. 
Notes to Consolidated Financial Statements 
(Tabular amounts in thousands of US Dollars, except share and per share amounts) 

Cash and cash equivalents, restricted cash and deposits 

Cash is comprised of cash on hand and demand deposits.  Cash equivalents, restricted cash and deposits are 
short-term,  highly  liquid  investments  with  original  maturities  of  three  months  or  less  that  are  readily 
convertible to known amounts of cash and which are subject to an insignificant risk of change in fair value.   

Trade receivables   

Trade receivables relate to amounts receivable from sales with fixed or determinable payments that are not 
quoted in an active market.  These receivables are non-interest bearing and are recognized at face amount, 
except  when  fair  value  is  materially  different,  and  are  subsequently  measured  at  amortized  cost.  Trade 
receivables recorded are net of lifetime expected credit losses.  

j) 

Impairment 

i)  Financial assets 

The Company recognizes a loss allowance for expected credit losses on financial assets that are measured at 
amortized cost. At each reporting date, the loss allowance for the financial asset is measured at an amount 
equal to the lifetime expected credit losses if the credit risk on the financial asset has increased significantly 
since initial recognition. If at the reporting date, the financial asset has not increased significantly since initial 
recognition, the loss allowance is measured for the financial asset at an amount equal to twelve months’ 
expected credit losses. For trade receivables the Company applies the simplified approach to providing for 
expected  credit  losses,  which  allows  the  use  of  a  lifetime  expected  loss  provision.  Impairment  losses  on 
financial  assets  carried  at  amortized  cost  are  reversed  in  subsequent  periods  if  the  amount  of  the  loss 
decreases  and  the  decrease  can  be  objectively  related  to  an  event  occurring  after  the  impairment  was 
recognized.    The  expected  lifetime  credit  loss  provision  for  trade  receivables  is  based  on  historical 
counterparty default  rates and adjusted for relevant  forward-looking information, when required. As  the 
Company’s  three  primary  significant  customers  are  considered  to  have  a  low  default  rate  and  historical 
default  rates  are  low,  the  lifetime  expected  credit  loss  allowance  for  trade  receivables  is  nominal  as  at 
December 31, 2020.  Accordingly, the Company did not record a provision for expected credit losses for trade 
receivables.   

ii)  Non-Financial assets 

At each reporting date the carrying amounts of the Company’s mineral, property, plant and equipment and 
exploration  and  evaluation  assets  are  reviewed  to  determine  whether  there  is  any  indication  that  those 
assets are impaired. If such indication exists, the recoverable amount of the asset is estimated in order to 
determine the extent of the impairment, if any.  The recoverable amount is the higher of fair value less costs 
to sell and value in use, which is the present value of future cash flows expected to be derived from the asset 
or its related cash generating unit.  For purposes of impairment testing, assets are grouped at the lowest 
levels that generate cash inflows from continuing use that are largely independent of the cash inflows of 
other assets or groups of assets (the “cash-generating unit”).

Ero Copper Corp. 
Notes to Consolidated Financial Statements 
(Tabular amounts in thousands of US Dollars, except share and per share amounts) 

If the recoverable amount of an asset or cash-generating unit is estimated to be less than its carrying amount, 
the carrying amount of the associated assets are reduced to their recoverable amount and the impairment 
loss is recognized in the profit or loss for the period. 

Impairment losses recognized in prior periods are assessed at each reporting date for any indications that 
the loss has decreased or no longer exists.  An impairment charge is reversed through profit or loss only to 
the extent  that the asset’s carrying amount  does not  exceed the carrying amount  that  would have been 
determined, net of any applicable depreciation, if no impairment loss had been recognized.    

k)  Provisions 

i)  Mine closure and rehabilitation provision 

The Company records the present value of estimated costs of legal and constructive obligations related to 
mine closure and rehabilitation in the period in which the obligation occurs.  Mine closure and rehabilitation 
activities include facility decommissioning and dismantling; removal and treatment of waste materials; site 
and land rehabilitation, including compliance with and monitoring of environmental regulations; and related 
costs  required  to  perform  this  work  and/or  operate  equipment  designed  to  reduce  or  eliminate 
environmental effects.  The provision is adjusted each period for new disturbances, and changes in regulatory 
requirements, the estimated amount of future cash flows required to discharge the obligation, the timing of 
such  cash  flows  and  the  pre-tax  discount  rate  specific  to  the  liability.    The  unwinding  of  the  discount  is 
recognized in profit or loss as a finance expense. 

When the provision is initially recognized, the corresponding cost is capitalized by increasing the carrying 
amount of the related asset and is amortized to profit or loss on a unit-of-production basis.   

ii)  Other provisions 

Other  provisions  are  recognized,  based  on  a  past  event,  when  the  Company  has  a  legal  or  constructive 
obligation  that  can  be  estimated  reliably,  and  it  is  probable  that  an  economic  mineral  resource  will  be 
required to settle the obligation. Provisions are measured by discounting the expected future cash flows at 
a pre-tax rate that reflects current market assessments of the time value of money and specific risks for the 
liability. The discount is unwound over the period over which the cash flows are expected to be incurred with 
the related expense included in finance expense. 

l)  Share-Based Compensation 

The  grant  date  fair  value  of  equity  settled  share-based  payment  awards  granted  to  employees  and 
consultants, including directors and officers, is recognized as an employee expense, with a corresponding 
increase in equity, over the period that the employees unconditionally become entitled to the awards. The 
amount recognized as an expense is adjusted to reflect the number of awards for which the related service 
and  non-market  vesting  conditions  are  expected  to  be  performed  or  satisfied  such  that  the  amount 
ultimately recognized as an expense is based on the number of awards that meet the related service and 
non-market performance conditions at the vesting date. Deferred share units are liability awards settled in 
cash and measured at the quoted market price at the grant date with the corresponding expense recognized 
over  the  period  that  the  employees  unconditionally  become  entitled  to  the  awards.    The  corresponding 
liability is adjusted for changes in fair value at each subsequent reporting date until the awards are settled. 

m) Leases 

A contract is or contains a lease when the contract conveys a right to control the use of an identified asset 
for a period of time in exchange for consideration.

Ero Copper Corp. 
Notes to Consolidated Financial Statements 
(Tabular amounts in thousands of US Dollars, except share and per share amounts) 

The Company recognizes a right-of-use asset and a lease liability at the lease commencement date.  The right-
of-use asset is initially measured at cost, and subsequently at cost less any accumulated depreciation and 
impairment losses, and adjusted for certain re-measurements of the lease liability. The cost of the right-of-
use asset includes the amount of the initial measurement of the lease liability, any lease payments made at 
or  before  the  commencement  date,  less  any  lease  incentives  received,  any  initial  direct  costs;  and  if 
applicable, an estimate of costs to be incurred by the Company in dismantling and removing the underlying 
asset, restoring the site on which it is located or restoring the underlying asset to the condition required by 
the terms and conditions of the lease.  

The lease liability is initially measured at the present value of the lease payments that are not paid at the 
commencement date, discounted using the interest rate implicit in the lease or, if that rate cannot be readily 
determined, the Company’s incremental borrowing rate. The incremental borrowing rate reflects the rate of 
interest that the lessee would have to pay to borrow the funds necessary to obtain an asset of similar value 
in  a  similar  economic  environment  with  similar  terms  and  conditions.  Generally,  the  Company  uses  its 
incremental borrowing rate as the discount rate.  

The lease liability is subsequently increased by the interest cost on the lease liability and decreased by lease 
payments made.  It is remeasured when there is a change in future lease payments arising from a change in 
an index or rate, a  change in the estimate of the amount  expected  to be payable under a  residual  value 
guarantee,  or  as  appropriate,  changes  in  the  assessment  of  whether  a  purchase  or  extension  option  is 
reasonably certain to be exercised or a termination option is reasonably certain not to be exercised. 

The Company does not recognize right-of-use assets and lease liabilities for leases of low-value assets and 
leases  with  lease  terms  that  are  less  than  12  months.  Lease  payments  associated  with  these  leases  are 
instead recognized as an expense over the lease term on either a straight-line basis, or another systematic 
basis if more representative of the pattern of benefit.   

The Company has applied judgement to determine the lease term for some lease contracts in which it is a 
lessee  that  include  renewal  options.    The  assessment  of  whether  the  Company  is  reasonably  certain  to 
exercise such options impacts the lease term, which significantly affects the amount of lease liabilities and 
right-of-use assets recognized. 

n) Income (Loss) per Share

Basic income (loss) per share is calculated by dividing the profit or loss attributable to common shareholders
of the Company by the weighted average number of common shares outstanding during the period.  Diluted
income (loss) per common share is calculated by adjusting the weighted average number of common shares
outstanding for the effect of conversion of all potentially dilutive share equivalents, such as stock options,
share  units  and  warrants.   The  dilutive  effect  of  share  options  and  warrants  assumes that  the  receipt  of
proceeds upon exercise of the options are used to repurchase common shares at the average market price
during the period.  The net effect of the shares issued less the shares assumed to be repurchased is added
to the basic weighted average shares outstanding.  For convertible instruments, the common shares to be
included in the diluted per share calculation assumes that the instrument is converted at the beginning of
the period (or the issue date if later). For Share Units (as defined herein, see note 12(b)), the common shares
to be included in the diluted per share calculation is based on the number of shares that would be issuable
if  the  reporting  date  were  the  end  of  the  vesting  period.    The  profit  or  loss  attributable  to  common
shareholders is adjusted to eliminate related interest costs of dilutive securities recognized in profit or loss
for the period.

6.  Mineral, Property, Plant and Equipment (continued) 

Of the additions to mineral, property, plant and equipment, $0.7 million (year ended December 31, 2019  – $8.6 
million) was obtained through financing arrangements with equipment suppliers.  

Certain equipment has been provided as security for the equipment finance loans (note 9). 

During  the  year  ended  December  31,  2020,  $7.3  million  (year  ended  December  31,  2019  -  $3.1  million)  was 
transferred from mineral resources to amortizable mineral reserves as a result of an update to MCSA’s proven and 
probable reserves during the year.  As such, there is no balance included in mineral, property, plant and equipment 
related to the value of mineral resources beyond proven and probable reserves not currently being amortized.  In 
addition, $56.8 million (December 31, 2019 - $52.7 million) related to projects in progress are not currently being 
amortized. 

7.  Exploration and Evaluation Assets 

Exploration and evaluation assets relate to the Boa Esperança Property located in the Municipality of Tucumã, in 
the state of Pará, Brazil which consists of a single mineral concession.  This prospective copper/gold property is in 
advanced stages of exploration with various geological mineral resource studies and is the subject of a completed 
feasibility study.

(a) Senior credit facility

The Company has a $150 million facility from a syndicate of Canadian financial institutions.  The facility is comprised 
of a $75 million (December 31, 2019 - $80 million) senior secured amortizing non-revolving credit facility (“Term 
Facility”)  and  a  $75  million  (December  31,  2019  -  $70  million)  senior  secured  revolving  term  credit  facility 
(“Revolving Credit Facility”) (collectively the “Facilities”).   

During the second quarter of 2019, the Company refinanced a loan held by the Company’s subsidiary, MCSA, by 
extending  the  Revolving  Credit  Facility.    The  credit  limit  of  the  Revolving  Credit  Facility  was  increased  by  $20.0 
million to $70.0 million.  All other terms of the Facilities remained unchanged.  Upon completion of the amendment, 
the Company drew $11.0 million to repay certain of its bank loans held by MCSA. 

On March 31, 2020, the Company amended the Facilities to reduce its cost of borrowing by 25 to 50 basis points, 
depending on the consolidated leverage ratio, and to defer the scheduled principal payments for two years. 

The Term Facility matures on March 31, 2024 and requires principal repayments on a quarterly basis commencing 
on March 31, 2022, while the Revolving Credit Facility is payable in full at maturity on March 31, 2024. The Facilities 
bear interest on a sliding scale at a rate of LIBOR plus 2.50% to 4.25% depending on the Company’s consolidated 
leverage ratio at the time.  Commitment fees for any undrawn portion of the Revolving Credit Facility are also on a 
sliding scale between 0.63%  to 1.06%.  The  Company determined that the amendments were a  non-substantial 
modification.  In March 2020, the Company drew down the remainder of the amount available under the Facilities 
totaling $14.0 million ($13.7 million net of transaction costs).  The Term Facility previously had a five-year term with 
equal quarterly principal payments beginning on December 13, 2020, while the Revolving Credit Facility was payable 
at maturity on December 13, 2022.  The Facilities previously bore interest on a sliding scale at a rate of LIBOR plus 
2.75% to 4.75% depending on the Company’s consolidated leverage ratio at the time.     

The  Facilities  include  standard  and  customary  terms  and  conditions  with  respect  to  fees,  representations, 
warranties, and financial covenants that remain unchanged from prior amendments.  

The Facilities are secured by pledges of shares of MCSA, NX Gold and Ero Gold Corp., a wholly owned subsidiary 
which  holds  the  Company’s  interest  in  NX  Gold.    The  Company  is  required  to  comply  with  certain  financial 
covenants.  As of the date of these consolidated financial statements, the Company is in compliance with these 
covenants. 

In January 2019, the Company entered into an interest rate swap transaction with a Canadian financial institution 
whereby the floating interest on a notional amount of $65.0 million of the Term Facility was swapped for a fixed 
interest  rate of 2.69%.  This interest  rate swap transaction is in effect for the  majority  of  the  term of the  Term 
Facility, with the notional amount reduced over time.  As at December 31, 2020, the notional amount of the interest 
rate swap transaction was $60.0 million.  Interest swap settlements are being made on a quarterly basis. 
Subsequent to the year ended December 31, 2020, the Facilities were amended with a $150.0 million senior secured 
revolving credit facility (“New Revolving Credit Facility”) payable entirely on March 31, 2025.  The New Revolving

Credit Facility will bear interest on a sliding scale at a rate of LIBOR plus 2.25 to 4.25% depending on the Company’s 
consolidated leverage ratio at the time.  Commitment fees for any undrawn portion of the Revolving Credit Facility 
will also be on a sliding scale between 0.56% to 1.06%.   

(b)  Bank loan and equipment finance loans 

The  bank  loan  (at  acquisition)  relates  to  the  Company’s  subsidiary,  MCSA,  and  was  recognized  at  the  date  of 
acquisition at fair value and has subsequently been recognized at amortized cost, net of settlements.  Interest is 
being recognized using the effective interest rate method at an interest rate of 11.29%.  

In June 2019, the Company repaid one of MCSA’s bank loans (at acquisition) in full using funds from the Company’s 
Revolving Credit Facility and recognized a loss on settlement of $1.8 million. 

As per the terms of one of MCSA’s bank loans, the Company was required to maintain a separate debt service bank 
account with sufficient funds to guarantee scheduled principal payments by MCSA.  At December 31, 2020, this loan 
has been repaid and the separate debt service bank account has been closed.  At December 31, 2019, $1.5 million 
was deposited in the designated debt service account and  was presented as restricted cash in the statement of 
financial position.   

MCSA is required to comply with certain financial covenants which MCSA is in compliance with at December 31, 
2020.  The equipment finance loans are secured by the corresponding equipment relating to them and a guarantee 
by the Company. 

(c)  MCSA and NX Gold lines of credit 

At December 31, 2020, the Company’s subsidiaries, MCSA and NX Gold, have the following credit facilities available: 

MCSA entered into a credit agreement in 2019 for a non-revolving line of credit of up to BRL $30.0 million at an 
interest rate of CDI (“Brazilian Interbank Deposit Rate”) + 9% per annum, which was available for draw down until 
November 30, 2020.  At December 31, 2020, BRL $7.5 million ($1.4 million) (December 31, 2019 - $nil) had been 
drawn from this credit facility and the draw down period has now expired.  The Company and NX Gold provide 
unsecured guarantees for this credit agreement and the amount drawn is due in March 2021. 

During the three months ended June 30, 2020, MCSA entered into a credit agreement for a line of credit of up to 
BRL $14.9 million at an interest rate of 14.30% per annum and MCSA drew down on the full amount of this line of 
credit. The Company and NX Gold provide unsecured guarantees for this credit agreement. During the three months 
ended December 31, 2020, the full amount of this line of credit was repaid, but the full amount of BRL $14.9 million 
remains available to be drawn at any time until May 24, 2021.

11.  Provisions and Contingent Liabilities 

(a)  Mine closure and rehabilitation 

The Company’s provision for mine closure and rehabilitation consists of costs accrued based on the current best 
estimate of mine closure and reclamation activities that will be required upon completion of mining. The Company’s 
provision for future site closure and reclamation costs is based on the level of known disturbance at the reporting 
date, known legal requirements and cost estimates prepared by a third-party specialist.  

Management used a pre-tax discount rates in the range of 5.75% – 7.37% (2019 – 4.34% - 6.5%) and an inflation 
factor in the range of 3.25% - 3.50% (2019 – 3.5% - 3.75%) in preparing the Company’s provision for mine closure 
and  rehabilitation.  Although  the  ultimate  amount  to  be  incurred  is  uncertain,  based  on  development,  legal 
requirements  and  estimated  costs  as  at  December  31,  2020,  the  undiscounted  inflation-adjusted  liability  for 
provision for mine closure and rehabilitation is estimated to be approximately $37.0 million (2019 - $45.7 million), 
of which $31.4 million (2019 - $36.8 million) relates to MCSA and $5.6 million (2019 - $8.9 million) relates to NX 
Gold. The cash expenditures are expected to occur over a period of time extending several years after the projected 
closure, which for MCSA is in a range from 2026 to 2034 and for NX Gold is 2027.   

(b)  Legal claims 

There are various legal actions that are in process against the Company’s Brazilian subsidiaries related to labor, 
civil and tax matters. Based on an analysis of individual judicial and administrative legal claims, the following 
provision has been made for probable losses associated with these claims: 

(i)  Labor claims 

The  labor  claims  related  primarily  to  claims  made  by  existing  and  former  employees  for  alleged  travel  time 
reimbursements, overtime and severance payments.  Of the claims made, the Company has assessed, with the 
assistance of its legal counsel, that the probable loss on such claims is $2.4 million and such amount has been 
accrued.

(ii) Tax claims

The provisions for tax claims relate to tax assessments, interest and penalties resulting from unpaid income and 
social contribution taxes by MCSA.   

In  relation  to  the  above-mentioned  claims  and  those  discussed  in  Note  11(c)  below,  MCSA  and  NX  Gold  were 
required to place a total of $0.5 million in trust as of December 31, 2020 (December 31, 2019 - $1.2 million), which 
is included in Deposits on the statement of financial position. 

(c) Contingent liabilities

As of December 31, 2020, based on the opinion of its legal advisers, the Company has not recognized a provision 
for the following claims of MCSA and NX Gold as it is not probable that a cash outflow will occur.   

(i) Social security tax

Social security claims relate to potential social security tax payments related to past payments to employees, 
including profit sharing, and payments made to external contractors.  The Company strongly believes, based 
on  precedent  court  case  rulings,  that  part  of  the  claim  will  be  cancelled  after  administrative  and  judicial 
discussions.  The estimated portion of the claim expected to be cancelled of $2.9 million is included in the table 
above.   

(ii) Tax

There are 121 tax claims (2019 – 129 tax claims) against MCSA which were evaluated as possible, but not probable, 
losses by external legal counsel.  The main subjects under discussion for the tax claims involve the validity of tax 
credits used to offset federal taxes.   

(iii) Mining

In  June  2019,  MCSA  was  notified  of  five  administrative  claims  filed  by  the  Nacional  Mining  Agency  regarding 
alleged differences in the calculation of certain sales taxes on mining revenue by MCSA.  The Company, based on 
the opinion of its legal advisors, does not believe such claims will result in a probable cash outflow. 

12. Share Capital

As at  December 31, 2020, the  Company’s  authorized share capital consists of an unlimited  number of common 
shares without par value.  As at December 31, 2020, 87,879,261 common shares were outstanding.

In determining the weighted average exercise price of all outstanding options in the tables above and below, the 
CAD prices were converted to USD at the December 31, 2020 exchange rate of 1.2732. 

The fair value of options granted in the years ended December 31, 2020 and 2019 was determined using the Black-
Scholes option pricing model.  The weighted average inputs used in the measurement of fair values at grant date of 
the options are the following: 

For the year ended December 31, 2020, the Company recorded share-based compensation of $3.9 million (year 
ended December 31, 2019 - $4.7 million) with respect to its outstanding stock options. 

Subsequent to December 31, 2020, 155,982 options were exercised for total proceeds of $1.0 million. 

(b)  Share Unit Plan

The Company has a share unit plan (the “Share Unit Plan”) pursuant to which the Compensation Committee may 
grant share units to any director, officer, employee, or consultant of the Company or its subsidiaries. At the time of 
grant of a share unit, the Compensation Committee, may establish performance conditions for the vesting of the 
share units. The performance conditions may be graduated such that different percentages (which may be greater 
or lower than 100%) of the  share units in a grant become vested depending on the satisfaction of one or more 
performance conditions. Performance conditions may include terms or conditions relating to: (i) the market price 
of the common shares; (ii) the return to holders of common shares, with or without reference to other comparable 
companies; (iii) the financial  performance or results of the Company or its subsidiaries; (iv) the achievement  of 
performance conditions or other performance criteria  relating to the Company or its subsidiaries; (v) any other 
terms and conditions the Compensation Committee may in its sole discretion determine with respect to vesting or 
the acceleration of vesting; and (vi) the vesting date of the share units. The Compensation Committee may, in its 
discretion, subsequent to the grant of a share unit, waive any such performance condition or determine that it has 
been satisfied subject to applicable law. Each share unit entitles the holder thereof to receive one common share, 
without payment of additional consideration, on the redemption date selected by the Compensation Committee 
following the date of vesting of such share unit, which will be within 30 days of the date of vesting, or at a later 
deferred date, subject to certain exception and restrictions. 

During the year ended December 31, 2020, 290,298 share units (year ended December 31, 2019 – 225,659 share 
units) were issued to certain officers, consultants and employees of the Company and as at December 31, 2020, 
727,761 share units (December 31, 2019 - 437,463 share units) are outstanding.  These share units will vest three 
years from the date of grant by the Compensation Committee and the number of share units that will vest may 
range  from  0%  to  200%  of  the  number  granted,  subject  to  the  satisfaction  of  certain  market  and  non-market 
performance conditions.  Each vested share unit entitles the holder thereof to receive on or about the applicable 
date of vesting of such share unit (i) one common share; (ii) a cash amount equal to the fair market value of one 
common  share  as  at  the  applicable  date  of  vesting;  or  (iii)  a  combination  of  (i)  and  (ii),  as  determined  by  the 
Compensation Committee in its sole discretion.  The Company currently intends to settle these share units using 
common shares.  Accordingly, they are classified as equity settled instruments.

(Tabular amounts in thousands of US Dollars, except share and per share amounts) 

For the share units with non-market performance conditions, the fair value of the share units granted was 
determined using the share price at the date of grant.  For the share units with market performance conditions, 
thefair value of the share units granted was determined using a Geometric Brownian Motion model.   The 
weighted average inputs used in the measurement of fair values at grant date of the share units issued are as 
follows: 

During the year ended December 31, 2020, the Company recorded share-based compensation of $3.9 million (year 
ended December 31, 2019 - $1.0 million) with respect to the share units. 

(c) Deferred Share Unit Plan

On December 12, 2019, a Deferred Share Unit Plan (“DSU Plan”) was established by the Board as a component of 
our compensation for independent directors. Only independent directors are eligible to participate and to receive 
deferred share units (“DSUs”) under the DSU Plan.  DSUs may be awarded by the Board from time to time to provide 
independent directors with appropriate equity-based compensation for the services they render to the Company 
and may be subject to terms and conditions with respect to vesting of such DSUs.  In addition, independent directors 
may elect to receive a portion or all of their respective annual cash remuneration in the form of DSUs, which will be 
fully vested upon such grant.  The number of DSUs to be awarded to a participant under the DSU Plan is determined 
by dividing the portion of that participant’s annual cash remuneration by the fair market value of a common share 
on the last day of the quarter in which such portion of the annual cash remuneration was earned. Pursuant to the 
DSU Plan, DSUs may only be settled by way of cash payment. A participant is not entitled to payment in respect of 
the DSUs until his or her death, retirement or removal from the Board.  The settlement amount of each DSU is based 
on the fair market value of a common share on the DSU redemption date multiplied by the number of DSUs being 
redeemed.  

During  the  year  ended  December  31,  2020,  79,230  DSUs  (year  ended  December  31,  2019  -  nil)  were  issued  to 
independent directors.  
As at December 31, 2020, the fair value of the DSU liability was $1.3 million (December 31, 2019 - $nil) which has 
been recognized in accounts payable and accrued liabilities with a corresponding $1.3 million recognized in share-
based compensation expense for the year ended December 31, 2020. 

(d) Warrants

As  at  December  31,  2020,  1,599,996  (December  31,  2019  -  2,866,662)  common  share  purchase  warrants  were 
outstanding with a weighted average exercise price of $1.20 and a weighted average remaining contractual life of 
0.95 years.  1,266,666 warrants were exercised during the year ended December 31, 2020 for gross proceeds of 
$1.5 million (year ended December 31, 2019 – 466,666 warrants for gross proceeds of $0.6 million).   

Subsequent to December 31, 2020, 66,666 warrants were exercised for gross proceeds of $0.1 million.

sale  based  on  the  previous  month’s  average  copper  price.   The  final  sales  price  for  all  shipments  in  a  month  is 
determined at the end of the month in which the sale is recognized.  As at December 31, 2020, there were no sales 
subject to provisional pricing.  During the year ended December 31, 2020, the Company recognized $2.2 million 
(year ended December 31, 2019 - $0.2 million) in price adjustments related to provisionally priced sales.

18.  Recovery of Value Added Taxes 

During the year ended December 31, 2020, the Company recognized a recovery of $8.9 million in net income related 
to value added taxes based on the tax treatment applicable to depletion charges.  This recovery during 2020 was 
recognized as a result of a study conducted to revisit certain tax positions, which concluded that it is probable that 
additional tax credits are available to be used to offset a variety of taxes.   During the year ended December 31, 
2019, the Company recognized a recovery of $21.6 million in net income related to value added taxes previously 
paid on sales in Brazil.  The recovery during 2019 was recognized as a result of a Brazil Supreme Court ruling in 2017 
that concluded that the relevant taxing authorities had historically used an incorrect methodology to determine 
such  taxes.   The  ruling  set  a  precedent  for  all  companies  in  Brazil  but  was  required  to  be  confirmed  for  the 
Company’s  specific  claim  and  were  not  recorded  until  such  amounts  were  considered  probable  of  being 
confirmed.  These credits can be used to offset the payment of a variety of other taxes, including income taxes and 
taxes on future sales.

Recognized deferred tax and assets and liabilities consist of the following: 

Deferred tax assets of $13.5 million (December 31, 2019 - $11.7 million) have not been recognized for the following 
deductible  temporary  differences  as  it  is  not  probable  that  the  benefits  of  these  temporary  differences  will  be 
realized: 

The Company has loss carry forwards in Brazil totalling $46.7 million (December 31, 2019 - $83.0 million) which may 
be carried forward indefinitely to offset future taxable income in Brazil. Use of these losses is limited to 30%  of 
taxable income annually.  The Company also has loss carry forwards in Canada totalling $24.9 million (December 
31, 2019 - $15.4 million) which may be carried forward for 20 years to offset future taxable income, which expire 
between 2036 and 2040.

20.  Related Party Transactions 

Key  management  personnel  consist  of  the  Company’s  directors  and  officers  and  their  compensation  includes 
director retainer fees and management salaries paid to these individuals, as well as share-based compensation.  The 
aggregate value of compensation paid to key management personnel for the year ended December 31, 2020 was 
$7.4 million ($7.5 million for the year ended December 31, 2019).  In addition, 287,281 options, 197,269 share units  
and 79,230 DSUs were issued to key management personnel and non-executive directors during the year ended 
December 31, 2020 (444,265 options and 171,754 share units for the year ended December 31, 2019).  For key 
management  personnel,  $5.1  million  was  recognized  in  share-based  compensation  expense  for  the  year  ended 
December 31, 2020 for options, share units, and DSUs issued ($4.1 million for the year ended December 31, 2019).   

During the year ended December 31, 2020, key management personnel exercised 408,555 options and 1,266,666 
warrants for total cash proceeds to the Company of $2.7 million (286,666 options and 300,000 warrants for total 
cash proceeds of $1.0 million for the year ended December 31, 2019). 

As at December 31, 2020, $3.7 million was payable to key management as incentive compensation and is included 
in accounts payable and accrued liabilities in the statement of financial position (December 31, 2019 - $3.9 million).  
Such amounts are unsecured, non-interest bearing and will be paid under normal trade terms. 

21.  Financial Instruments 

Fair value 

Fair values of financial assets and liabilities are determined based on available market information and valuation 
methodologies appropriate to each situation. However, some judgments are required in the interpretation of the 
market data to produce the most appropriate fair value estimates.  The use of different market information and/or 
evaluation methodologies may have a material effect on the fair value amounts. 

As at December 31, 2020, derivatives were measured at fair value based on Level 2 inputs.   

The carrying values of cash and cash equivalents, accounts receivable, deposits, and accounts payable and accrued 
liabilities  approximate  their  fair  values  due  to  their  short terms  to  maturity  or  market  rates  of  interest  used  to 
discount amounts.  The carrying value of value added, payroll and other taxes approximate fair value based on the 
discount rate applied.  At December 31, 2020, the carrying value of loans and borrowings is $168.1 million while the 
fair value is approximately $169.9 million.  The stated interest rates are a close approximation of market rates of 
interest at December 31, 2020 (Level 2 of the fair value hierarchy).  

Credit risk  

Credit risk is the risk of financial loss to the Company if a customer or counterparty to a financial instrument fails to 
meet its contractual obligations and arises principally from the Company’s receivables from customers. The carrying 
amount of the financial assets below represents the maximum credit risk exposure as at December 31, 2020 and 
December 31, 2019:

The Company invests cash and cash equivalents with financial institutions that are financially sound based on their 
credit rating.  The Company’s exposure to credit risk associated with accounts receivable is influenced mainly by 
the individual characteristics of each customer.  The Company currently has only three significant customers, all of 
which have no history of credit default with the Company.  The Company has not incurred credit losses during the 
years ended December 31, 2020 and 2019 nor recognized a provision for credit losses.     

Liquidity risk  

Liquidity  risk  is  the  risk  associated  with  the  difficulties  that  the  Company  may  have  meeting  the  obligations 
associated  with  financial  liabilities  that  are  settled  with  cash  payments  or  with  another  financial  asset.  The 
Company's approach to liquidity management is to ensure as much as possible that sufficient liquidity exists to meet 
their  maturity  obligations  on  the  expiration  dates,  under  normal  and  stressful  conditions,  without  causing 
unacceptable losses or with risk of undermining the normal operation of the Company.  

The table below shows the Company's maturity of non-derivative financial liabilities on December 31, 2020: 

The  Company  also  has  derivative  financial  liabilities  for  foreign  exchange  and  interest  rate  derivatives  whose 
notional amounts and maturity information is disclosed below under foreign exchange currency risk and interest 
rate risk. 

Market risk  

Market risk is the risk of loss that may arise from changes in market factors such as interest rates, foreign exchange 
rates,  and  commodity  prices.    The  purpose  of  market  risk  management  is  to  manage  and  control  exposures  to 
market risks, within acceptable parameters, while optimizing return. 
The Company may use derivatives, including forward contracts and swap contracts, to manage market risks.   

(i) Foreign exchange currency risk  

The Company’s subsidiaries in Brazil are exposed to exchange risks related to the US dollars and Euros.  In order to 
minimize  currency  mismatches,  the  Company  monitors  its  cash  flow  projections  considering  future  sales 
expectations indexed to US dollar variation in relation to the cash requirement to settle the existing financings. 

The Company's exposure to foreign exchange currency risk at December 31, 2020 relates to $7.4 million (December 
31, 2019 – $9.6 million) in loans and borrowings of MCSA denominated in US dollars and Euros.  In addition, the 
Company  is  also  exposed  to  foreign  exchange  currency  risk  at  December  31,  2020  on  $83.1  million  due  to  an 
intercompany  loan  balance  (December  31,  2019  -  $97.8  million)  which  has  contractual  repayment  terms.  
Strengthening (weakening) in the Brazilian Real against the US dollar at December 1, 2020 by 10% and 20%, would 
have increased (decreased) pre-tax net income by $8.9 million and $17.7 million, respectively (2019 – $10.3 million 
and $20.7 million). Strengthening (weakening) in the Brazilian Real against the Euro at December 31, 2020 by 10% 
and 20%, would have increased (decreased) pre-tax net income by $0.2 million and $0.4 million, respectively (2019 
–  $0.4  million  and  $0.8  million).  This  analysis  is  based  on the  foreign  currency  exchange  variation  rate  that  the 
Company considered to be reasonably possible at the end of the year. The analysis assumes that all other variables, 
especially interest rates, are held constant.

Ero Copper Corp. 
Notes to Consolidated Financial Statements 
(Tabular amounts in thousands of US Dollars, except share and per share amounts) 

The Company may use derivatives, including forward contracts, collars and swap contracts, to manage market risks. 
At December 31, 2020, the Company has entered into foreign exchange collar contracts at zero cost for notional 
amounts of $285.7 million with an average floor rate of 4.05 BRL to US Dollar and an average cap rate of 4.76 BRL 
to US Dollar (December 31, 2019 - notional amount of $336.6 million in foreign exchange forward collar contracts).  
The maturity dates of these contracts are from January 27, 2021 to July 27, 2022 and are financially settled on a net 
basis.  The fair value of these contracts at December 31, 2020 was a liability of $34.5 million, (December 31, 2019 - 
$nil) which is included in Derivatives in the statement of financial position.  The fair value of these forward contracts 
as at December 31, 2020 was determined using an option pricing mode with the following assumptions: discount 
rate of 5.015%, foreign exchange rate of approximately 5.20, and volatility of 7.46% - 21.20%. The change in fair 
value of foreign exchange collar contracts was a loss of $34.5 million for the year ended December 31, 2020 (a loss 
of  $0.3  million  for  the  year  ended  December  31,  2019)  and  has  been  recognized  in  foreign  exchange  loss.    In 
addition, during the year ended December 31, 2020, the Company recognized a realized loss of $20.8 million ($1.0 
million  for  the  year  ended  December  31,  2019)  related  to  the  settlement  of  foreign  currency  forward  collar 
contracts. 

(ii) Interest rate risk

The Company is principally exposed to the variation in interest rates on loans and borrowings with variable rates of 
interest.   Management reduces interest rate risk exposure by entering into loans and borrowings with fixed rates 
of interest or by entering into derivative instruments that fix the ultimate interest rate paid. 

The Company is principally exposed to interest rate risk through its Term Facilities of $150.0 million, Brazilian Real 
denominated bank loans of $4.5 million, Brazilian Real denominated  lines of credit of $1.4 million, and Brazilian 
Real denominated equipment finance loans of $1.1 million.  Based on the Company’s net exposure at December 31, 
2020, a 1% change in the variable rates would have an impact of $1.6 million on pre-tax annual net income, without 
consideration of the effects of the interest rate swap contract below. 

In order to mitigate the above volatility due to variable rates on loans, as at December 31, 2020, the Company has 
entered into an interest rate swap contract to manage interest rate risk (see note 9(a)).  At December 31, 2020, the 
floating interest on a notional amount of $60.0 million was swapped for a fixed interest rate of 2.69%.  This interest 
rate swap transaction is in effect for the majority of the term of the Term Facility (note 9), with the notional amount 
reduced over time.  The fair value of this contract at December 31, 2020 was a liability of $2.5 million (December 
31, 2019 - $1.7 million) and was included in Derivatives in the statement of financial position.  The fair value of this 
swap contracts as at December 31, 2020 was determined using a discounted cash flow model with the following 
assumptions:  discount  rates  of  0.017%  –  0.298%  and  forward  foreign  exchange  rates  of  0.421%  -  0.164%.  The 
realized loss on the interest rate swap contract was $1.2 million for the year ended December 31, 2020 (realized 
loss of $0.1 million for the year ended December 31, 2019) and was included in finance expense.  In addition, the 
Company  recognized  an  unrealized  loss  of  $0.8  million  on  the  interest  rate  swap  contract  for  the  year  ended 
December 31, 2020 (unrealized loss of $1.6 million for the year ended December 31, 2019), which was included in 
finance expense. 

In addition, as at December 31, 2020, MCSA has entered into an interest rate and currency swap contract on the 
Plural Loan (see note 9).  At December 31, 2020, the floating interest on a notional amount of BRL$12 million was 
swapped for a fixed interest rate of 9.9% and the BRL currency on the loan was swapped for USD at a rate of 3.95.  
The fair value of this contract at December 31, 2020 was a liability of $0.3 million (December 31, 2019 - nil) and is 
included  in  Derivatives  in  the  statement  of  financial  position.    The  realized  loss  on  this  swap  contract  was  $0.4 
million for the year ended December 31, 2020 and was included in finance expense.  In addition, the Company 
recognized an unrealized loss of $0.3 million on the swap contract for the year ended December 31, 2020, which 
was also included in finance expense.

(iii) Price risk

The Company may use derivatives, including forward contracts, collars and swap contracts, to manage commodity 
price risks.  At December 31, 2020, the Company has not entered into any commodity derivative contracts.  The 
Company recognized a realized loss of $1.4 million for the year ended December 31, 2019 related to the settlement 
of commodity forward contracts. 

22. Capital Management

The Company’s objectives when managing capital are to safeguard the Company’s ability to continue as a going 
concern in order to pursue the development and production of its mine properties and to maintain a flexible capital 
structure for its projects for the benefit of its stakeholders. 

In the management of capital, the Company includes the components of shareholders’ equity and debt facilities. 

The  Company  manages  the  capital  structure  and  makes  adjustments  to  it  considering  changes  in  the  economic 
conditions and the risk characteristics of the underlying assets.  To maintain or adjust the capital structure, the 
Company may attempt to issue new loans and borrowings, common shares, or acquire or dispose of assets. 

Management reviews the capital structure on a regular basis to ensure that the above-noted objectives are met. 

Certain loan agreements contain operating and financial covenants that could restrict the ability of the Company 
and  its  subsidiary,  MCSA,  to,  among  other  things,  incur  additional  indebtedness  needed  to  fund  its  respective 
operations,  pay  dividends  or make  other  distributions,  make  investments,  create  liens,  sell  or  transfer  assets  or 
enter into transactions with affiliates.  There are no other restrictions or externally imposed capital requirements 
of the Company.

This Annual Report contains “forward-looking information” within the meaning of applicable Canadian securities laws. Forward-looking information
includes statements that use forward-looking terminology such as “may”, “could”, “would”, “will”, “should”, “intend”, “target”, “plan”, “expect”,
“budget”, “estimate”, “forecast”, “schedule”, “anticipate”, “believe”, “continue”, “potential”, “view” or the negative or grammatical variation thereof or
other variations thereof or comparable terminology. Such forward-looking information includes, without limitation, statements with respect to mineral
reserve and mineral resource estimates as well as LOM plans; targeting additional mineral resources and expansion of deposits; the Company’s
expectations, strategies and plans for the MCSA Mining Complex, the NX Gold Property and the Boa Esperança Property, including the Company’s
planned exploration, development and production activities; the significance of any particular exploration program or result and the Company’s
expectations for current and future exploration plans including, but not limited to, planned areas of additional exploration, the significance of any drill
results or new discoveries and targets, including without limitation, extensions of defined mineralized zones, possibilities for mine life extensions or
continuity of high-grade mineralization, the recoverable value of any metals other than copper, further extensions and expansion of mineralization near
the Company’s existing operations and throughout the Curaçá Valley or the NX Gold Mine, the timing and advancement of ongoing projects including
the Deepening Extension Project and the re-start of the Surubim open pit mine; estimated completion dates for certain milestones; successfully adding
or upgrading mineral resources and successfully developing new deposits; the costs and timing of future exploration and development including but
not limited to the Deepening Extension Project at the MCSA Mining Complex; the significance of any potential optimization initiatives in connection
with the Boa Esperança Property and the potential issuance, and timing of, an OFS; the impact of the COVID-19 pandemic on the Company’s planned
drill programs; the timing and amount of future production at the MCSA Mining Complex and the NX Gold Property; ; the representativeness of the
material tested in the Company’s ore sorting trial campaign to actual results of each of the mines tested during the campaign and the potential benefits
of ore sorting in the LOM plans at any of the Company's operations including the Vermelhos District as well as any potential savings on transport costs,
any potential reduction in water, diesel and electricity use, as well as any proposed reductions in flotation tailings as a result of ore sorting
implementation, which may or may not occur in any capacity at the Company's operations or life-of-mine plans now or in the future, the Company's
ability to service its ongoing obligations, the Company's future production outlook, cash costs, capital resources, expenditures, the impact of new
accounting standards and amendments on the Company's financial statements, and current global macroeconomic uncertainty stemming from the
COVID-19 pandemic and its impact on the Company’s business, financial condition, results of operations, cash flows and prospects.

Forward-looking information is not a guarantee of future performance and is based upon a number of estimates and assumptions of management in
light of management’s experience and perception of trends, current conditions and expected developments, as well as other factors that management
believes to be relevant and reasonable in the circumstances, as of the date of this Annual Report including, without limitation, assumptions about:
continued effectiveness of the measures taken by the Company to mitigate the possible impact of COVID-19 on its workforce and operations;
favourable equity and debt capital markets; the ability to raise any necessary additional capital on reasonable terms to advance the production,
development and exploration of the Company’s properties and assets; future prices of copper and other metal prices; the timing and results of
exploration and drilling programs; the accuracy of any mineral reserve and mineral resource estimates; the geology of the MCSA Mining Complex, NX
Gold Property and the Boa Esperanҫa Property being as described in the technical reports for these properties; production costs; the accuracy of
budgeted exploration and development costs and expenditures; the price of other commodities such as fuel; future currency exchange rates and
interest rates; operating conditions being favourable such that the Company is able to operate in a safe, efficient and effective manner; work force
conditions to remain healthy in the face of prevailing epidemics, pandemics or other health risks (including COVID-19), political and regulatory
stability; the receipt of governmental, regulatory and third party approvals, licenses and permits on favourable terms; obtaining required renewals for
existing approvals, licenses and permits on favourable terms; requirements under applicable laws; sustained labour stability; stability in financial and
capital goods markets; availability of equipment and critical supplies, spare parts and consumables; positive relations with local groups and the
Company’s ability to meet its obligations under its agreements with such groups; and satisfying the terms and conditions of the Company’s current
loan arrangements. While the Company considers these assumptions to be reasonable, the assumptions are inherently subject to significant business,
social, economic, political, regulatory, competitive, global health, and other risks and uncertainties, contingencies and other factors that could cause
actual actions, events, conditions, results, performance or achievements to be materially different from those projected in the forward-looking
information. Many assumptions are based on factors and events that are not within the control of the Company and there is no assurance they will
prove to be correct.

Furthermore, such forward-looking information involves a variety of known and unknown risks, uncertainties and other factors which may cause the
actual plans, intentions, activities, results, performance or achievements of the Company to be materially different from any future plans, intentions,
activities, results, performance or achievements expressed or implied by such forward-looking information. Such risks include, without limitation the
risk factors listed under the heading “Risk Factors” in the Annual Information Form for the year ended December 31, 2020 and dated March 16, 2021.

Although the Company has attempted to identify important factors that could cause actual actions, events, conditions, results, performance or
achievements to differ materially from those described in forward-looking information, there may be other factors that cause actions, events,
conditions, results, performance or achievements to differ from those anticipated, estimated or intended.

The Company cautions that the foregoing lists of important assumptions and factors are not exhaustive. Other events or circumstances could cause
actual results to differ materially from those estimated or projected and expressed in, or implied by, the forward-looking information contained herein.
There can be no assurance that forward-looking information will prove to be accurate, as actual results and future events could differ materially from
those anticipated in such information. Accordingly, readers should not place undue reliance on forward-looking information.

Forward-looking information contained herein is made as of the date of this Annual Report and the Company disclaims any obligation to update or
revise any forward-looking information, whether as a result of new information, future events or results or otherwise, except as and to the extent

C1 cash cost of copper produced (per lb) is the sum of production costs, net of capital expenditure development costs and by-product credits, divided
by the copper pounds produced. C1 cash costs reported by the Company include treatment, refining charges, offsite costs, and certain tax credits
relating to sales invoiced to the Company’s Brazilian customer on sales. By-product credits are calculated based on actual precious metal sales (net of
treatment costs) during the period divided by the total pounds of copper produced during the period. C1 cash cost of copper produced per pound is
a non-IFRS measure used by the Company to manage and evaluate operating performance of the Company’s operating mining unit, and is widely
reported in the mining industry as benchmarks for performance, but does not have a standardized meaning and is disclosed in addition to IFRS
measures.
