CAUTIONARY  NOTE  TO  INVESTORS  REGARDING  ESTIMATES  OF  MEASURED,  INDICATED  AND 
INFERRED RESOURCES AND PROVEN AND PROBABLE MINERAL RESERVES 

Our  technical  report  entitled  “NI  43-101  Technical  Report  Mt  Todd  Gold  Project  50,000  tpd  Preliminary  Feasibility 
Study Northern Territory, Australia” with an effective date of September 10, 2019 and an issue date of October 7, 2019, 
referenced herein, uses the terms “mineral reserve”, “proven mineral reserve” and “probable mineral reserve” as defined 
in Canadian National Instrument 43-101 – Standards of Disclosure for Mineral Projects (“NI 43-101”) and the Canadian 
Institute  of  Mining,  Metallurgy  and  Petroleum  (the “CIM”)  –  CIM  Definition  Standards  on  Mineral  Resources  and 
Mineral Reserves, adopted by the CIM Council, as amended (the “CIM Definition Standards”). These definitions differ 
from  the  definitions  in  the  United States  Securities  and  Exchange  Commission  (“SEC”)  Industry  Guide  7 
(“SEC Industry Guide 7”) under the United States Securities Act of 1933, as amended (the “Securities Act”). Under SEC 
Industry  Guide  7 standards,  a  “final”  or  “bankable”  feasibility  study  is  required  to  report  reserves,  the  three-year 
historical  average  metal  price  is  used  in  any  reserve  or  cash  flow  analysis  to  designate  reserves,  and  the  primary 
environmental analysis or report must be filed with the appropriate governmental authority. 

In  addition,  the  terms  “mineral  resource”,  “measured  mineral  resource”,  “indicated  mineral  resource”  and  “inferred 
mineral resource” are defined in and required to be disclosed by NI 43-101; however, these terms are not defined terms 
under SEC Industry Guide 7 and are normally not permitted to be used in reports and registration statements filed with 
the SEC. Investors are cautioned not to assume that all or any part of a mineral deposit in these categories will ever be 
converted into reserves under SEC Industry Guide 7. “Inferred mineral resources” have a great amount of uncertainty as 
to their existence, and great uncertainty as to their economic, technical and legal feasibility. It cannot be assumed that all, 
or any part, of an inferred mineral resource will ever be upgraded to a higher category. Under Canadian rules, estimates 
of inferred mineral resources may not form the basis of feasibility or preliminary feasibility studies, except in rare cases. 
Investors  are  cautioned  not  to  assume  that  all  or  any  part  of  an  inferred  mineral  resource  exists  or  is  economically, 
technically or legally mineable. Disclosure of “contained ounces” in a resource is permitted disclosure under Canadian 
regulations; however, the SEC normally only permits issuers to report mineralization that does not constitute “reserves” 
by SEC standards as in place tonnage and grade without reference to unit measures. 

Accordingly,  information  contained  in  this  report  and  the  documents  incorporated  by  reference  herein  contain 
descriptions of our mineral deposits that may not be comparable to similar information made public by other companies 
subject  to  the  reporting  and  disclosure  requirements  under  the  United States  federal  securities  laws  and  the  rules  and 
regulations thereunder.  

The term “mineralized material” as used in this annual report on Form 10-K, although permissible under SEC Industry 
Guide  7,  does  not  indicate  “reserves”  by  SEC  Industry  Guide  7  standards.  We  cannot  be  certain  and  investors  are 
cautioned not to assume that all or any part of the mineralized material will ever be confirmed or converted into SEC 
Industry Guide 7 compliant “reserves” that can be economically or legally extracted. 

The SEC has adopted amendments to its disclosure rules to modernize the mineral property disclosure requirements for 
issuers whose securities are registered with the SEC. These amendments became effective February 25, 2019 (the “SEC 
Modernization  Rules”)  and,  following  a  two-year  transition  period,  the  SEC  Modernization  Rules  will  replace  the 
historical  property  disclosure  requirements  for  mining  registrants  that  are  included  in  SEC  Industry  Guide  7.  The 
Company  is  not  required  to  provide  disclosure  on  its  mineral  properties  under  the  SEC  Modernization  Rules  until  its 
fiscal year beginning January 1, 2021. Under the SEC Modernization Rules, the definitions of “proven mineral reserves” 
and  “probable  mineral  reserves”  have  been  amended  to  be  substantially  similar  to  the  corresponding  CIM  Definition 
Standards and the SEC has added definitions to recognize “measured mineral resources”, “indicated mineral resources” 
and  “inferred  mineral  resources”  which  are  also  substantially  similar  to  the  corresponding  CIM  Definition  Standards; 
however  there  are  differences  in  the  definitions  and  standards  under  the  SEC  Modernization  Rules  and  the  CIM 
Definition Standards and therefore once the Company begins reporting under the SEC Modernization Rules there is no 
assurance that the Company’s mineral reserve and mineral resource estimates will be the same as those reported under 
CIM Definition Standards as contained in the technical report or that the economics for the Mt Todd project estimated in 
the technical report will be the same as those estimated in any technical report prepared by the Company under the SEC 
Modernization Rules in the future.

metal. 

“assay”  means  to  test  ores  or  minerals  by  chemical  or  other  methods  for  the  purpose  of  determining  the  amount  of 
valuable metals contained. 

“bedding” means the characteristic structure of sedimentary rock in which layers of different composition, grain size or 
arrangement are layered one on top of another in a sequence with oldest on the bottom and youngest at the top.

“chalcopyrite” means a brass-yellow colored sulfide of copper and iron. It is a copper mineral. 

“claim”  means  a  mining  title  giving  its  holder  the  right  to  prospect,  explore  for  and  exploit  minerals  within  a 
defined area. 

“clastic” refers to sedimentary rock (such as shale or siltstone) or sediment. An accumulation of transported weathered 
debris.  

“comminution” means the process in which solid materials are broken into small fragments by crushing, grinding, and 
other processes.  

“conglomerate” refers to clastic sedimentary rock that contains rounded particles that are greater than two millimeters in 
diameter. The space between the pebbles is generally filled with smaller particles and/or a chemical cement that binds 
the rock together.  

“cut-off grade” means the grade below which mineralized material will be considered waste. 

“deposit” is an informal term for an accumulation of mineralized material. 

“exploration stage enterprise” refers to an issuer engaged in the search for mineral deposits (reserves) which are not in 
either the development or production stage, per SEC Industry Guide 7. A development stage enterprise is engaged in the 
preparation of an established, commercially minable deposit (reserve) which is not in the production stage. A production 
stage enterprise is engaged in the exploitation of commercially viable mineral deposits (reserves). 

“facies” means the characteristics of a rock mass that reflects its depositional environment.  

“fault” means a fracture in rock along which there has been displacement of the two sides parallel to the fracture. 

“feasibility  study”  is  a  comprehensive  technical  and  economic  study of  the  selected development  option for  a  mineral 
project  that  includes  appropriately  detailed  assessments  of  realistically  assumed  mining,  processing,  metallurgical, 
economic,  marketing,  legal,  environmental,  social  and  governmental  considerations  together  with  any  other  relevant 
operational  factors  and  detailed  financial  analysis,  that  are  necessary  to  demonstrate  at  the  time  of  reporting  that 
extraction is reasonably justified or economically viable. The results of the study may reasonably serve as the basis for a 
final  decision  by  a  proponent  or  financial  institution  to  proceed  with,  or  finance,  the  development  of  a  project.  The 
confidence level of the study will be higher than that of a preliminary feasibility study. 

“felsic” is a term used to describe an igneous rock that has a large percentage of light-colored minerals such as quartz, 
feldspar  and  muscovite.  Felsic  rocks  are  generally  rich  in  silicon  and  aluminum  and  contain  only  small  amounts  of 
magnesium and iron.

“ferruginous” means containing iron oxides or rust. 

“foliation” means planar arrangement of structural or textural features in any rock type. 

“fold” is a bend or flexure in a rock unit or series of rock units caused by crust movements.  

“g Au/t” means grams of gold per tonne.  

“galena” means a lead sulfide mineral commonly found in hydrothermal veins; it is the primary ore of lead. 

“geosyncline” means a major trough or downwarp of the Earth’s crust, in which great thicknesses of sedimentary and/or 
volcanic rocks have accumulated.  

“greywackes” means fine-grained sandstone generally characterized by its hardness, dark color and poorly sorted angular 
grains of quartz, feldspar and small rock fragments set in a compact, clay-fine matrix.  

“heap leach” means a gold extraction method that percolates a cyanide solution through ore heaped on an impermeable 
pad or base. 

“hornfels”  refers  to  nonfoliated  metamorphic  rock  that  is  typically  formed  by  contact  metamorphism  around  igneous 
intrusions. 

“indicated mineral resource” and “indicated resource” means “indicated mineral resource” as defined by the CIM in the 
CIM Definition Standards and is that part of a mineral resource for which quantity, grade or quality, densities, shape and 
physical  characteristics  are  estimated  with  sufficient  confidence  to  allow  the  appropriate  application  of  technical  and 
economic  parameters  in  sufficient  detail  to  support  mine  planning  and  evaluation  of  the  economic  viability  of  the 
deposit. Geological evidence is derived from adequately detailed and reliable exploration, sampling and testing and is 
sufficient  to  assume  geological  and  grade  or  quality  continuity  between  points  of  observation.  An  indicated  mineral 
resource has a lower level of confidence than that applying to a measured mineral resource and may only be converted to 
a probable mineral reserve. 

“inferred  mineral  resource”  and  “inferred  resource”  means  “inferred  mineral  resource”  as  defined  by  the  CIM  in  the 
CIM Definition Standards and is that part of a mineral resource for which quantity and grade or quality are estimated on 
the  basis  of  limited  geological  evidence  and  sampling.  Geological  evidence  is  sufficient  to  imply  but  not  verify 
geological  and  grade  or  quality  continuity.  An  inferred  mineral  resource  has  a  lower  level  of  confidence  than  that 
applying to an indicated mineral resource and must not be converted to a mineral reserve. It is reasonably expected that 
the majority of inferred mineral resources could be upgraded to indicated mineral resources with continued exploration. 

“intrusion”  refers  to  an  igneous  rock  body  that  formed  from  magma  that  forced  its  way  into,  through  or  between 
subsurface rock units.  

“intrusives” refers to igneous rocks that crystallize below the earth’s surface. 

“ironstone”  is  a  sedimentary  rock,  either  deposited  directly  as  a  ferruginous  sediment  or  created  by  chemical 
replacement,  that  contains  a  substantial  proportion  of  an  iron  compound  from  which  iron  either  can  be  or  once  was 
smelted commercially.  

“joint” means a fracture in a rock along which there has been no displacement. 

“measured mineral resource” and “measured resource” means “measured mineral resource” as defined by the CIM in 
the CIM Definition Standards and is that part of a mineral resource for which quantity, grade or quality, densities, shape 
and physical characteristics are estimated with confidence sufficient to allow the application of technical and economic 
parameters to support detailed mine planning and final evaluation of the economic viability of the deposit. Geological

evidence is derived from detailed and reliable exploration, sampling and testing and is sufficient to confirm geological 
and  grade  or  quality  continuity  between  points  of  observation.  A  measured  mineral  resource  has  a  higher  level  of 
confidence  than  that  applying  to  either  an  indicated  mineral  resource  or  an  inferred  mineral  resource.  It  may  be 
converted to a proven mineral reserve or to a probable mineral reserve. 

“mica”  any  of  a  group  of  phyllosilicate  minerals  having  similar  chemical  compositions  and  highly  perfect  basal 
cleavage. 

“mineral  reserve”  means  the  economically  mineable  part  of  a  measured  mineral  resource  and/or  indicated  mineral 
resource.  It  includes  diluting  materials  and  allowances  for  losses,  which  may  occur  when  the  material  is  mined  or 
extracted and is defined by studies at preliminary feasibility or feasibility level as appropriate that include application of 
mining,  processing,  metallurgical,  infrastructure,  economic,  marketing,  legal,  environmental,  social,  governmental  or 
other relevant factors. Such studies demonstrate that, at the time of reporting, extraction could reasonably be justified.  

“mineral resource” means a concentration or occurrence of solid material of economic interest in or on the earth’s crust 
in  such  form,  grade  or  quality  and  quantity  that  there  are  reasonable  prospects  for  eventual  economic  extraction.  The 
location,  quantity,  grade  or  quality,  continuity  and  other  geological  characteristics  of  a  mineral  resource  are  known, 
estimated or interpreted from specific geological evidence and knowledge, including sampling.  

“mineralization” means the concentration of valuable minerals within a body of rock. 

“mineralized  material”  under  SEC Industry  Guide  7 is  a  mineralized  body  that  has  been  delineated  by  appropriately 
spaced  drilling  and/or  underground  sampling  to  support  a  sufficient  tonnage  and  average  grade  of  metal(s).  Such  a 
deposit does not qualify as a reserve until a comprehensive evaluation based upon unit cost, grade, recoveries, and other 
material factors conclude legal and economic feasibility. Mineralized material is generally equivalent to measured plus 
indicated mineral resources but does not include inferred mineral resources. 

“mudstone” is a fine-grained sedimentary rock whose original constituents were clays or muds.  

“ore”  means  material  containing  minerals  in  such  quantity,  grade  and  chemical  composition  that  they  can  be 
economically extracted. 

“ore  sorting”  means  technology  that  separates  “ore”  and  “waste”  based  on  physical  and/or  chemical  properties  of  the 
material being sorted.  

“oxide”  means  mineralized  rock  in  which  some  of  the  original  minerals  have  been  oxidized  (i.e.,  combined  with 
oxygen). Oxidation tends to make the ore more porous and permits a more complete permeation of cyanide solutions so 
that minute particles of gold in the interior of the minerals will be more readily dissolved. 

“preliminary  economic  assessment”  as  defined  by  NI  43-101  is  a  study,  other  than  a  preliminary  feasibility  study  or 
feasibility study, that includes an economic analysis of the potential viability of mineral resources.  

“preliminary feasibility study” and “PFS” as defined by the CIM in the CIM Definition Standards is a comprehensive 
study of  a range  of options for  the  technical  and  economic  viability  of  a  mineral  project  that  has  advanced  to  a  stage 
where a preferred mining method, in the case of underground mining, or the pit configuration, in the case of an open pit, 
is  established  and  an  effective  method  of  mineral  processing  is  determined.  It  includes  a  financial  analysis  based  on 
reasonable  assumptions  on  mining,  processing,  metallurgical,  economic,  marketing,  legal,  environmental,  social  and 
government considerations and the evaluation of any other relevant factors which are sufficient for a qualified person, 
acting reasonably, to determine if all or part of the mineral resource may be converted to a mineral reserve at the time of 
reporting. A preliminary feasibility study is at a lower confidence level than a feasibility study. 

“probable  reserves”  under  SEC Industry  Guide  7 means  reserves  for  which  quantity  and  grade  and/or  quality  are 
computed  from  information  similar  to  that  used  for  proven  reserves,  but  the  sites  for  inspection,  sampling  and 

4 

 
 
 
 
 
 
 
 
 
 
 
 
measurement are farther apart or are otherwise less adequately spaced. The degree of assurance, although lower than that 
for proven reserves, is high enough to assume continuity between points of observation. 

“probable mineral reserves” as defined by the CIM in the CIM Definition Standards is the economically mineable part 
of  an  indicated  and,  in  some  circumstances,  a  measured  mineral  resource.  The  confidence  in  the  mining,  processing, 
metallurgical, economic, and other relevant factors applying to a probable mineral reserve is lower than that applying to 
a proven mineral reserve. 

“proven  reserves”  under  SEC Industry  Guide  7 means  reserves  for  which  (a) quantity  is  computed  from  dimensions 
revealed  in  outcrops,  trenches,  workings  or  drill holes; grade  and/or  quality  are  computed  from  the  results  of detailed 
sampling and (b) the sites for inspection, sampling and measurement are spaced so closely and the geologic character is 
so well defined that size, shape, depth and mineral content of reserves are well established. 

“proven mineral reserves”, as defined by the CIM in the CIM Definition Standards, is the economically mineable part of 
a measured mineral resource A proven mineral reserve implies a high degree of confidence in the mining, processing, 
metallurgical, economic and other relevant factors. 

“pyrrhotite” means a bronze-colored magnetic ferrous sulfide mineral consisting of iron and sulfur.  

“pyrite” means a pale brass-yellow colored iron sulfide mineral consisting of iron and sulfur. 

“qualified  person”  as  defined  under  NI 43-101 means  an  individual  who  (a) is  an  engineer  or  geoscientist  with  a 
university degree, or equivalent accreditation, in an area of geoscience, or engineering, relating to mineral exploration or 
mining;  (b)  has  at  least  five  years  of  experience  in  mineral  exploration,  mine  development  or  operation,  or  mineral 
project  assessment  or  any  combination  of  these  that  is  relevant  to  his  or  her  professional  degree  or  area  of  practice; 
(c) has experience relevant to the subject matter of the mineral project and the technical report; (d) is in good standing 
with  a  professional  association;  and  (e)  in  the  case  of  a  professional  association  in  a  foreign  jurisdiction,  has  a 
membership designation that (i) requires attainment of a position of responsibility  in their profession that requires the 
exercise  of  independent  judgment;  and  (ii)  requires  (A)  a  favorable,  confidential  peer  evaluation  of  the  individual’s 
character, professional judgment, expertise and ethical fitness; or (B) a recommendation for membership by at least two 
peers,  and  demonstrated  prominence  or  expertise  in  the  field  of  mineral  exploration  or  mining.  Note:  a  professional 
association  is  a  self-regulatory  organization  of  engineers,  geoscientists  or  both  that,  among  other  criteria,  requires 
compliance  with  the  professional  standards  of  competence  and  ethics  established  by  the  organization  and  has 
disciplinary powers over its members. 

“recovery”  means  that  portion  of  the  metal  contained  in  the  ore  that  is  successfully  extracted  by  processing  and  is 
expressed as a percentage. 

“sampling” means selecting a fractional, but representative, part of a mineral deposit for analysis. 

“scats” means material in a ball mill or sag mill that has become rounded and no longer susceptible to additional size 
reduction. Basically, this material may be rejected from the grinding circuit for additional crushing because it contributes 
to higher energy consumption within the mill.  

“schist” is a metamorphic rock containing abundant particles of mica, characterized by strong foliation and originating 
from a metamorphism in which directed pressure played a significant role.  

“sediment” means solid material settled from suspension in a liquid. 

“sedimentary  rock”  means  rock  formed  from  the  accumulation  and  consolidation  of  sediment,  usually  in  layered 
deposits.  

“shale”  is  a  fine grained,  clastic  sedimentary  rock  composed of  mud  that  is  a  mix  of  flakes of clay  minerals  and  tiny 
fragments (silt-sized particles) or other minerals, especially quartz and calcite.  

5 

 
 
 
 
 
 
 
 
 
 
 
 
 
“silicified” means to become converted into or impregnated with silica. 

“siltstone” is a sedimentary rock that has a grain size in the silt range, finer than sandstone and coarser than claystones. 

“sphalerite” means a zinc sulfide mineral commonly found in hydrothermal veins; it is the primary ore of zinc. 

“strike” when used as a noun, means the direction, course or bearing of a vein or rock formation measured on a level 
surface and, when used as a verb, means to take such direction, course or bearing. 

“sulfide” means a compound of sulfur and some other element. From a metallurgical perspective, sulfide rock is primary 
ore that has not been oxidized. Both ore and waste may contain sulfide minerals. 

“tailings” means material rejected from a mill after most of the valuable minerals have been extracted. 

“tonne” means a metric tonne and has the weight of 1,000 kg or 2,204.6 pounds. 

“tpd” means tonnes per day.  

“tuffs” are a type of rock consisting of consolidated volcanic ash ejected from vents during a volcanic eruption.  

“vein” means a fissure, fault or crack in a rock filled by minerals that have traveled upwards from some deep source. 

“waste” means rock lacking sufficient grade and/or other characteristics of ore.

ITEM 1. BUSINESS.  

Overview 

PART I 

Vista Gold Corp. and its subsidiaries (collectively, “Vista,” the “Company,” “we,” “our,” or “us”) operate in the gold 
mining  industry. We  are  focused  on  the  evaluation,  acquisition,  exploration  and  advancement  of gold  exploration and 
potential development projects that may lead to gold production or value adding strategic transactions such as earn-in 
right agreements, option agreements, leases to third parties, joint venture arrangements with other mining companies, or 
outright sales of assets for cash and/or other consideration. We look for opportunities to improve the value of our gold 
projects through exploration drilling and/or technical studies focused on optimizing previous engineering work. We do 
not currently generate cash flows from mining operations. 

The  Company’s  flagship  asset  is  its  100%  owned  Mt  Todd  gold  project  (“Mt  Todd”  or  the  “Project”)  in  Northern 
Territory (“NT”) Australia. Mt Todd is the largest undeveloped gold project in Australia. We have invested substantial 
amounts  to  evaluate,  engineer,  permit  and  de-risk  the  Project.  We  believe  these  efforts  have  added  to  the  underlying 
value of the Project and demonstrate strong development potential. In January 2018, the Company announced positive 
results  of  an  updated  preliminary  feasibility  study  for  Mt  Todd  (the  “2018  PFS”).  In  2018  and  2019,  we  continued 
additional metallurgical testing that demonstrated improved gold recovery compared to the 2018 PFS. These test results, 
other findings and the outcome of an independent benchmarking study were incorporated into an updated preliminary 
feasibility  study,  which  was  issued  in  October  2019  (as  further  described  below,  the  “2019  PFS”).  The  2019  PFS 
successfully  confirmed  the  efficiency  of  ore  sorting  across  a  broad  range  of  head  grades,  the  natural  concentration  of 
gold in the screen undersize material prior to sorting, the economics of fine grinding and the resulting improved gold 
recoveries, and the selection of FLSmidth’s VXP mill as the preferred fine grinding mill. 

Vista  was  originally  incorporated  on  November 28,  1983  under  the  name  “Granges  Exploration Ltd.”  It  amalgamated 
with  Pecos  Resources  Ltd.  during  June  1985  and  continued  as  Granges  Exploration  Ltd.  In  June  1989,  Granges 
Exploration Ltd. changed its name to Granges Inc. Granges Inc. amalgamated with Hycroft Resources & Development 
Corporation during May 1995 and continued as Granges Inc. Effective November 1996, Da Capo Resources Ltd. and 
Granges,  Inc.  amalgamated  under  the  name  “Vista  Gold  Corp.”  and,  effective  December  1997,  Vista  continued  from 
British Columbia to the Yukon Territory, Canada under the Business Corporations Act (Yukon Territory). On June 11, 
2013,  Vista  continued  from  the  Yukon  Territory,  Canada  to  the  Province  of  British  Columbia,  Canada  under  the 
Business  Corporations  Act  (British  Columbia).  The  current  addresses,  telephone  and facsimile  numbers of our  offices

Corporate Organization Chart  

The name, place of incorporation, continuance or organization and percent of equity securities that we own or control as 
of February 6, 2020 for each of our subsidiaries is set out below.  

Employees 

As of December 31, 2019, we had 15 full-time and no part-time employees globally. In addition, we use consultants with 
specific  skills  to  assist  with  various  aspects  of  our  corporate  affairs,  project  evaluation,  due  diligence,  corporate 
governance and property management. 

Segment Information 

We  have  one  reportable  segment,  consisting  of  evaluation,  acquisition  and  exploration  activities  which  are  focused 
principally in Australia. We evaluate, acquire, explore and advance gold exploration and potential development projects, 
which  may  lead  to  gold  production  or  value  adding  strategic  transactions  such  as  earn-in  right  agreements,  option 
agreements,  leases  to  third  parties,  joint  venture  arrangements,  or  outright  sales  of  assets.  We  reported  no  operating 
revenues during the years ended December 31, 2019 and 2018. Geographic location of mineral properties and plant and 
equipment  is  provided  in  Notes  4  –  Mineral  Properties  and  5  –  Plant  and  Equipment  to  our  Consolidated  Financial 
Statements under the section heading “Item 8. Financial Statements and Supplementary Data” below. 

Reclamation 

We generally will be required to mitigate long-term environmental impacts by stabilizing, contouring, re-sloping and re-
vegetating various portions of a site after mining and mineral processing operations are completed. These reclamation 
efforts would be conducted in accordance with detailed plans, which must be reviewed and approved by the appropriate 
regulatory agencies. 

The  Mt  Todd  site  was  not  reclaimed  when  the  mine  closed  in  the  late  1990’s.  Liability  for  the  reclamation  of  the 
environmental conditions existing prior to the 2006 commencement of Vista’s involvement with the Project remains the 
responsibility  of  the  NT  Government  until  after  we  have  provided  notice  to  the  NT  Government  that  we  intend  to 

12 

 
 
 
 
 
 
 
 
 
 
proceed  with  development  and  assume  rehabilitation  liability  for  Mt  Todd.  Vista  does  not  expect  to  give  such  notice 
until a production decision has been made, the Project is fully permitted to construct the mine, and necessary financing 
for Project construction can be arranged.  

In 2016, the Province of British Columbia Ministry of Energy and Mines (“MEM”) requested that the Company prepare 
and present to MEM a reclamation plan for closure and abandonment of certain mining claims in British Columbia that 
the Company disposed of in 1996. Vista presented a reclamation plan to MEM in April 2017; however, execution of the 
reclamation plan has not started, as acceptance by MEM is pending. Assuming no other potentially responsible parties 
are identified and based on preliminary estimates of the reclamation and other related costs, we have accrued $240 as of 
December 31, 2019. 

Government Regulation 

Our exploration and development activities and other property interests are subject to various national, state, provincial 
and  local  laws  and  regulations  in  Australia  and  other  jurisdictions,  which  govern  prospecting,  development,  mining, 
production,  exports,  taxes,  labor  standards,  occupational  health,  waste  disposal,  protection  of  the  environment,  mine 
safety,  hazardous  substances  and  other  matters.  We  have  obtained  or  have  pending  applications  for  those  licenses, 
permits or other authorizations currently required to conduct our exploration and other programs. We believe we are in 
compliance in all material respects with applicable mining, health, safety and environmental statutes and regulations in 
all of the jurisdictions in which we operate. With the exception of the British Columbia claims noted above, management 
of  the  Company  is  not  aware  of  any  current  orders  or  directions  relating  to  the  Company  with  respect  to  the 
aforementioned laws and regulations.  

Australia Laws  

Mineral  projects  in  the  NT  are  subject  to  Australian  federal  and  NT  laws  and  regulations  regarding  environmental 
matters and the discharge of hazardous wastes and materials. As with all mining projects, Mt Todd is expected to have a 
variety of environmental impacts should development proceed. In Australia, environmental legislation plays a significant 
role  in  the  mining  industry.  We  are  required  under  Australian  laws  and  regulations  (federal,  state  and  territorial)  to 
acquire  permits  and  other  authorizations  before  Mt  Todd  can  be  developed  and  mined.  In  September  2014,  the 
environmental  impact  statement  (“EIS”)  for  Mt  Todd  was  approved.  The  Environmental  Protection  Agency  of  the 
Northern Territory Government (“NTEPA”) advised that it had assessed the environmental impacts of the proposed gold 
mine at Mt Todd and authorized the Company to proceed with development, subject to a number of recommendations as 
outlined  in  the  assessment  report  (the  “Assessment  Report”).  The  Assessment  Report  included  a  request  for 
authorization under the federal Environmental Protection and Biodiversity Conservation Act 1999 (“EPBC”) as it relates 
to the Gouldian Finch. In January 2018, the authorization under the EPBC was approved by the Australia Department of 
the Environment and Energy. We must comply with the terms of our Authority Certificate under the Northern Territory 
Aboriginal Sacred Sites Act 1989 which deals with the handling of archeological material within sacred sites. We are 
also subject to statutory requirements under the Mining Management Act, which includes the requirement to complete a 
Mine Management Plan (“MMP”) before the start of mining operations. The Mt Todd MMP was formally submitted in 
November 2018 and is under review by the NT Department of Primary Industries and Resources (“DPIR”). 

Environmental Regulation 

Our projects are subject to various federal, state and local laws and regulations governing protection of the environment. 
These laws are continually changing and, in general, are becoming more restrictive. Our policy is to conduct business in 
a  way  that  safeguards  public  health  and  the  environment.  We  believe  that  our  operations  are  conducted  in  material 
compliance with applicable laws and regulations. 

Changes  to  current  local,  territorial,  state  or  federal  laws  and  regulations  in  the  jurisdictions  where  we  operate  could 
require additional capital expenditures and increased operating and/or reclamation costs. We are unable to predict what 
additional legislation, if any, might be proposed or enacted, or what additional regulatory requirements could impact the 
economics of our projects. 

13 

 
 
 
 
  
 
 
 
 
During 2019, none of our project sites had any material non-compliance occurrences with any applicable environmental 
regulations. See “Item 1. Business – Reclamation” above.  

Competition 

We compete with other mining companies in connection with the acquisition, exploration, financing and development of 
gold properties. There is competition among mining companies for a limited number of gold acquisition and exploration 
opportunities. Some of these competing mining companies have substantially greater financial and technical resources 
than Vista. As a result, we may have difficulty acquiring attractive gold projects at reasonable prices. We compete with 
other  mining  companies  to  retain  expert  consultants  required  to  complete  our  geological  and  project  development 
studies. We also compete with other mining companies to hire mining engineers, geologists and other skilled personnel 
in the mining industry, and for exploration and development services. 

Gold Price History 

The price of gold is volatile and is affected by numerous factors, all of which are beyond our control, such as the sale or 
purchase of gold by various central banks and financial institutions, inflation, recession, fluctuation in the relative values 
of the U.S. dollar and foreign currencies, changes in global gold demand and political and economic conditions. 

The following table presents the high, low and average afternoon fixed prices in U.S. dollars for an ounce of gold on the

ITEM 1A. RISK FACTORS. 

An investment in our securities involves a high degree of risk. The risks described below are not the only ones facing the 
Company  or  otherwise  associated  with  an  investment  in  our  securities.  Additional  risks  not  presently  known  to  us  or 
which we currently consider not material may also adversely affect our business. If any of the following risks actually 
occur, our business, financial condition and operating results could be materially adversely affected. 

Operating Risks 

We cannot be assured that Mt Todd is feasible or that a feasibility study will accurately forecast economic results. 

Mt Todd is our principal asset. Our future profitability depends largely on the economic feasibility of the Project. Before 
arranging financing for Mt Todd, we will have to complete a feasibility study. The results of our feasibility study may 
not  be  as  favorable  as  the  results  of  our  prefeasibility  studies.  There  can  be  no  assurance  that  the  mining  and 

14 

 
 
 
 
 
 
 
 
 
 
    
     
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
comminution processes including ore sorting, gold production rates, revenue, capital and operating costs including taxes 
and royalties will not vary unfavorably from the estimates and assumptions included in such feasibility study. 

Mt Todd requires substantial capital investment and we may be unable to raise sufficient capital on favorable terms 
or at all.  

The construction and operation of Mt Todd will require significant capital. Our ability to raise sufficient capital and/or 
secure  a  development  partner  on  satisfactory  terms,  if  at  all,  will  depend  on  several  factors,  including  a  favorable 
feasibility study, acquisition of the requisite permits, macroeconomic conditions, and future gold prices. Uncontrollable 
factors  or  other  factors  such  as  lower  gold  prices,  unanticipated  operating  or  permitting  challenges,  perception  of 
environmental impact or, illiquidity in the debt markets or equity markets, could impede our ability to finance Mt Todd 
on acceptable terms, or at all. 

If  we  decide  to  construct  the  mine  at  Mt  Todd,  we  will  be  assuming  certain  reclamation  obligations  resulting  in  a 
material financial obligation.  

The Mt Todd site was not reclaimed when the original mine closed. Although we are not currently responsible for the 
reclamation of these historical disturbances, we will accept full responsibility for them if and when we make a decision 
to finance and construct the mine and provide notice to the NT Government of our intention to take over and assume the 
management,  operation  and  rehabilitation  of  Mt  Todd.  At  such  time,  we  will  be  required  to  provide  a  bond  or  other 
surety in a form and amount satisfactory to the NT Government (in whose jurisdiction Mt Todd is located) that would 
cover the prospective expense to reclaim the property. In addition, the regulatory authorities may increase reclamation 
and  bonding  requirements  from  time  to  time.  The satisfaction of  these  bonding  requirements  and  continuing  or future 
reclamation obligations will require a significant amount of capital.  

We may not be able to get the required permits to begin construction at Mt Todd in a timely manner or at all.  

Any  delay  in  acquiring  the  requisite  permits,  or  failure  to  receive  required  governmental  approvals  could  delay  or 
prevent the start of construction of Mt Todd. If we are unable to acquire permits to mine the property, then the Project 
cannot be developed and operated. In addition, the property would have no reserves under SEC Industry Guide 7 and NI 
43-101, which could result in an impairment of the carrying value of the Project. 

There may be other delays in the construction of Mt Todd. 

Delays in commencing construction could result from factors such as availability and performance of engineering and 
construction  contractors,  suppliers,  consultants,  and  employees;  availability  of  required  equipment;  and  availability  of 
capital.  Any  delay  in  performance  by  any  one  or  more  of  the  contractors,  suppliers,  consultants,  employees  or  other 
persons  on  which  we  depend,  or  lack  of  availability  of  required  equipment,  or  delay  or  failure  to  receive  required 
governmental approvals, or financing could delay or prevent commencement of construction at Mt Todd. There can be 
no  assurance  of  whether  or  when  construction  at  Mt  Todd  will  start  or  that  the  necessary  personnel,  equipment  or 
supplies will be available to the Company if and when construction is started.  

Increased costs could impede our ability to become profitable. 

Capital and operating costs at mining operations are subject to variation due to a number of factors, such as changing ore 
grade, changing metallurgy, and revisions to mine plans in response to the physical shape and location of the ore body. 
In addition, costs are affected by the cost of capital, tax and royalty regimes, trade tariffs, the global cost of mining and 
processing equipment, commodity prices, foreign exchange rates, fuel, electricity, operating supplies and appropriately 
skilled labor. These costs are at times subject to volatile price movements, including increases that could make future 
development and production at Mt Todd less profitable or uneconomic. This could have a material adverse effect on our 
business prospects, results of operations, cash flows and financial condition.

We cannot be assured that we will have an adequate water supply for mining operations at Mt Todd. 

Water  at  Mt  Todd  is  expected  to  be  provided  from  a  fresh  water  reservoir  that  is  fed  by  seasonal  rains.  Insufficient 
rainfall, or drought-like conditions in the area feeding the reservoir could limit or extinguish this water supply. Sufficient 
water  resources  may  not  be  available,  resulting  in  curtailment  or  stoppage  of  operations  until  the  water  supply  is 
replenished. This could have a material adverse effect on our business prospects, results of operations, cash flows and 
financial condition. 

We could be subject to litigation, allegations or other legal claims. 

Our assets or our business activities may be subject to disputes that may result in litigation or other legal claims. We may 
be subject to allegations through press, social media, the courts or other mediums that may or may not be founded. We 
may be required to respond to or defend against these claims and/or allegations, which will divert resources away from 
our principal business. There can be no assurance that our defense of such claims and/or allegations would be successful, 
and  we  may  be  required  to  make  material  settlements.  This  could  have  a  material  adverse  effect  on  our  business 
prospects, results of operations, cash flows, financial condition and corporate reputation. 

We rely on third parties to fulfill their obligations under agreements. 

Our business strategy includes entering into agreements with third-parties (“Partners”), who may earn the right to obtain 
an  interest  in  certain  of  our  projects,  in  part  by  managing  the  respective  project.  Whether  or  not  we  hold  a  majority 
interest in a respective project, our Partner(s) may: (i) have economic or business interests or goals that are inconsistent 
with or opposed to ours; (ii) exercise veto rights to block actions that we believe to be in the best interests of the project; 
(iii)  take  action  contrary  to  our  policies  or  objectives;  or  (iv)  as  a  result  of  financial  or  other  reasons,  be  unable  or 
unwilling to fulfill their obligations under the respective joint venture, option, earn-in right or other agreement(s), such 
as contributing capital for the expansion or maintenance of projects. Any one or a combination of these could result in 
liabilities  for  us  and/or  could  adversely  affect  the  value  of  the  related  project(s)  and,  by  association,  damage  our 
reputation and consequently our ability to acquire or advance other projects and/or attract future Partners. 

Our exploration and development interests are subject to evolving environmental regulations. 

Our property and royalty interests are subject to environmental regulations. Environmental legislation is becoming more 
restrictive  in  some  jurisdictions,  with  stricter  standards  and  enforcement,  increased  fines  and  penalties  for  non-
compliance, more stringent environmental assessments of proposed projects, and a heightened degree of responsibility 
for companies and their officers, directors and employees. There is no assurance that future changes in environmental 
regulation,  if  any,  will  not  adversely  affect  our  interests.  Currently,  our  property  and  royalty  interests  are  subject  to 
government environmental regulations in Australia, Indonesia, Mexico and the U.S. 

We could be subject to environmental lawsuits. 

Neighboring landowners and other third parties could file claims based on environmental statutes and common law for 
personal injury and property damage allegedly caused by environmental nuisance, the release of hazardous substances or 
other waste material into the environment  on or around our properties. There can be no assurance that our defense of 
such  claims  would  be  successful.  This  could  have  a  material  adverse  effect  on  our  business  prospects,  financial 
condition, results of operation, and corporate reputation.  

We may have material undisclosed environmental liabilities of which we are not aware.  

Vista has been engaged in gold exploration since 1983. Since inception the Company has been involved in numerous 
exploration projects in many jurisdictions. There may be environmental liabilities associated with disturbances at any of 
these  projects  for  which  the  Company  may  be  identified  as  a  potentially  responsible  party,  regardless  of  its  level  of 
involvement  in  creating  the  related  disturbance.  We  may  not  be  aware  of  such  claims  against  the  Company  until 
regulators provide notice thereof. Consequently, we may have material undisclosed environmental responsibilities which 

16 

 
 
 
 
 
 
 
 
 
 
 
could negatively affect our business prospects, financial condition and cash flows, results of operations, and corporate 
reputation.  

There may be challenges to our title to mineral properties. 

There  may  be  challenges  to  our  title  to  our  mineral  properties.  If  there  are  title  defects  with  respect  to  any  of  our 
properties, we may be required to compensate other persons or reduce or lose our interest in the affected property. Also, 
in any such case, the investigation and resolution of title issues could divert Company resources from our core strategies.  

Opposition to Mt Todd could have a material adverse effect. 

There  is  generally  an  increasing  level  of  public  concern  relating  to  extractive  industries.  Opposition  to  extractive 
industries, or our development and operating plans at Mt Todd specifically, could have adverse effects on our reputation 
and  support  from  other  stakeholders.  As  a  result,  we  may  be  unable  to  attract  a  partner,  secure  adequate  financing  or 
complete other activities necessary to continue our planned activities. Any resulting delays or an inability to develop and 
operate Mt Todd as planned could have a material adverse effect on our business prospects, results of operations, cash 
flows, financial condition and corporate reputation. 

Our  exploration  and  development  activities,  strategic  transactions,  or  any  acquisition  activities  may  not  be 
commercially successful and could fail to lead to gold production or fail to add value. 

Substantial expenditures are required to acquire gold properties, establish mineral reserves through drilling and analysis, 
develop  metallurgical  processes  to  extract  metal  from  the  ore  and  develop  the  mining  and  processing  facilities  and 
infrastructure  at  any  site  chosen  for  mining.  We  cannot  be  assured  that  any  mineral  reserves  or  mineral  resources 
acquired,  discovered  or  established  will  be  in  sufficient  quantities  or  at  sufficient  grades  to  justify  commercial 
operations, attract a strategic partner or strategic transaction, or that the funds invested in them will ever be recovered. 

Financial and Business Risks 

A substantial or extended decline in gold prices would have a material adverse effect on the value of our assets, on 
our ability to raise capital and could result in lower than estimated economic returns.  

The value of our assets, our ability to raise capital and our future economic returns are substantially dependent on the 
price  of  gold.  The  gold  price  fluctuates  continually  and  is  affected  by  numerous  factors  beyond  our  control.  Factors 
tending to influence gold prices include:  

 

 
 
 
 
 

 
 
 
 

gold  sales  or  leasing  by  governments  and  central  banks  or  changes  in  their  monetary  policy,  including  gold 
inventory management and reallocation of reserves;  
speculative short or long positions on futures markets; 
the relative strength of the U.S. dollar; 
expectations of the future rate of inflation; 
interest rates; 
changes  to  economic  conditions  in  the  United  States,  China,  India  and  other  industrialized  or  developing 
countries; 
geopolitical conflicts; 
changes in jewelry, investment or industrial demand; 
changes in supply from production, disinvestment and scrap; and 
forward sales by producers in hedging or similar transactions. 

A substantial or extended decline in the gold price could: 

 
 

negatively impact our ability to raise capital on favorable terms, or at all; 
jeopardize the development of Mt Todd; 

17 

 
 
 
 
 
 
 
 
 
 
 
 
 

 
 
 

reduce  our  existing  estimated  mineral  resources  and  reserves  by  removing  material  from  these  estimates  that 
could not be economically processed at lower gold prices;  
reduce the potential for future revenues from gold projects in which we have an interest;  
reduce funds available to operate our business; and 
reduce the market value of our assets, including our investment in Midas Gold Shares. 

General economic conditions may have material adverse consequences. 

General  economic  conditions  and  financial  market  turmoil  may  arise  from  many  sources.  These  conditions  could 
potentially  impact  the  natural  resource  sector  and  Vista.  This  could  include  contraction  in  credit  markets  resulting  in 
widening of credit risk, imposition of trade tariffs among various countries, devaluations, high volatility in global equity, 
commodity,  foreign  exchange  and  gold  markets,  and  a  lack  of  market  liquidity.  These  and  other  factors  could  have  a 
material adverse effect on our business prospects, results of operations, cash flows and financial condition. 

Industry consolidation could result in the acquisition of a control position in the Company for less than fair value.  

Consolidation  within  the  industry  is  a  growing  trend.  As  a  result  of  the  broad  range  of  market  and  industry  factors 
including the price of gold, we believe the current market value of the common shares in the capital of the Company (the 
“Common  Shares”)  does  not  reflect  the  fair  value  of  the  Company’s  assets.  These  conditions  could  result  in  the 
acquisition of a control position, or attempted acquisition of a control position in the Company at what we believe to be 
less than fair value. This could result in substantial costs to us and divert our management’s attention and resources. A 
completed acquisition could result in realized losses of shareholder value.  

We have a history of losses, and we do not expect to generate earnings from operations or pay dividends in the near 
term, if at all. 

We  are  an  exploration  stage  enterprise.  As  such,  we  devote  our  efforts  to  exploration,  analysis  and,  if  warranted, 
development of our projects. We do not currently produce gold and do not currently generate operating earnings from 
gold production. We finance our business activities principally by issuing equity and selling non-core assets.  

We  have  incurred  losses  in  all  periods  since  1998,  except  for  the  year  ended  December  31,  2011,  during  which  we 
recorded non-cash net gains, and the year ended December 31, 2015 during which we recorded gains related to research 
and development (“R&D”) refunds. We expect to continue to incur losses. We have no history of paying cash dividends 
and we do not expect to be able to pay cash dividends or to make any similar distribution in the foreseeable future, if at 
all. 

We may be unable to raise additional capital on favorable terms, or at all. 

Our  exploration  and,  if  warranted,  development  activities  and  the  construction  and  start-up  of  any  mining  operation 
require substantial amounts of capital. In order to develop Mt Todd, acquire attractive gold projects, and/or continue our 
business,  we  will  have  to  secure  a  development  partner  or  otherwise  source  sufficient  equity  and  debt  capital,  raise 
additional funds from the sale of non-core assets and / or seek additional sources of capital from other external sources. 
There can be no assurance that we will be successful in raising additional capital on acceptable terms. If we cannot raise 
sufficient additional capital, we may be required to substantially reduce or cease operations, any of which may affect our 
ability to continue as a going concern. 

Our business is subject to evolving corporate governance and public disclosure regulations that have increased both 
our compliance costs and the risk of noncompliance. 

We  are  subject  to  changing  rules  and  regulations  promulgated  by  a  number  of  governmental  and  self-regulated 
organizations,  including  the  British  Columbia  Securities  Commission,  the  SEC,  the  Toronto  Stock  Exchange  (the 
“TSX”), the NYSE American, and the Financial Accounting Standards Board. These rules and regulations continue to 
evolve in scope and complexity and many new requirements have been created in response to laws enacted by the United 

18 

 
 
 
 
 
 
 
 
 
 
  
States Congress, making compliance increasingly more difficult and uncertain, which could have an adverse effect on 
reputation and our stock price. 

We face intense competition in the mining industry. 

The mining industry is intensely competitive in all of its phases. Some of our competitors are much larger, established 
companies  with  greater  financial  and  technical  resources  than  ours.  We  compete  with  other  companies  for  attractive 
mining properties, for capital, for equipment and supplies, for outside services and for qualified managerial and technical 
employees.  Access  to  financing,  equipment,  supplies,  skilled  labor  and  other  resources  may  also  be  affected  by 
competition from non-mining related commercial sectors. If we are unable to raise sufficient capital, we will be unable 
to  execute  exploration  and  development  programs  or  such  programs  may  be  reduced  in  scope.  Competition  for 
equipment  and  supplies  could  result  in  shortage  of  necessary  supplies  and/or  increased  costs.  Competition  for outside 
services  could  result  in  increased  costs,  reduced  quality  of  service  and/or  delays  in  completing  services.  If  we  cannot 
successfully  retain  or  attract  qualified  employees,  our  ability  to  advance  the  development  of  Mt  Todd,  to  attract 
necessary financing, to meet all of our environmental and regulatory responsibilities, or to take opportunities to improve 
our business, could be negatively affected. This could have a material adverse effect on our business prospects, results of 
operations, cash flows and financial condition. 

The occurrence of events for which we are not insured may affect our cash flow and overall profitability.  

We  maintain  insurance  policies  that  mitigate  certain  risks  related  to  our  operations.  This  insurance  is  maintained  in 
amounts that we believe to be reasonable based on the circumstances surrounding each identified risk. However, we may 
elect to limit or not have insurance for certain risks because of the high premiums associated with insuring those risks or 
for  various  other  reasons.  In  other  cases,  insurance  may  not  be  available  for  certain  risks.  We  do  not  insure  against 
political risk. Occurrence of events for which we are not insured adequately, or at all, could result in significant losses 
that could materially adversely affect our financial condition and our ability to fund our business.  

Our share price may be volatile and your investment in our Common Shares could suffer a decline in value.  

Broad  market  and  industry  factors  may  adversely  affect  the  price  of  our  Common  Shares,  regardless  of  our  actual 
operating  performance.  Factors  that  could  cause  fluctuation  in  the  price  of  our  Common  Shares  may  include,  among 
other things: 

 

 

 
 
 
 
 
 

changes  in  financial  estimates  by  us  or  by  any  securities  analysts  who  might  cover  our  stock  market 
performance; 
stock market price and volume fluctuations of other publicly traded companies and, in particular, those that are 
in the mining industry; 
speculation about our business in the press or the investment community; 
conditions or trends in our industry or the economy generally; 
changes in the prices of gold; 
announcements by us or our competitors of significant acquisitions, strategic partnerships or divestitures; 
additions or departures of key personnel; and 
sales of our Common Shares, including sales by our directors, officers or significant stockholders. 

In the past, securities class action litigation has often been instituted against companies following periods of volatility in 
their stock price. This type of litigation could result in substantial costs to us and divert our management’s attention and 
resources. 

Currency fluctuations may adversely affect our costs. 

We  have  material  property  interests  in  Australia.  Most  costs  in  Australia  are  incurred  in  the  local  currency.  The 
appreciation of the Australian dollar, if any, against the U.S. dollar effectively increases our cost of doing business in 
Australia. This could have the effect of increasing the amount of capital required to continue to explore and develop Mt 
Todd, and/or reducing the pace at which it is developed.  

19 

 
 
 
 
 
 
 
 
 
 
Our Australian R&D grants are subject to review.  

The  Australian  R&D  tax  incentive  program,  under  which  we  have  received  certain  grants  related  to  qualifying  R&D 
programs and expenditures, is a self-assessment process, and as such, the Australian Government has the right to review 
our  qualifying  programs  and  related  expenditures.  If  such  a  review  were  to  occur,  and  as  a  result  of  the  review  and 
failure  of  a  related  appeal  a  qualified  program  and  related  expenditures  were  disqualified,  the  respective  R&D  grant 
could be recalled with penalties and interest.  

The Company is likely a “passive foreign investment company,” which will likely have adverse U.S. federal income 
tax consequences for U.S. shareholders.  

U.S. shareholders of our Common Shares should be aware that the Company believes it was classified as a PFIC up to 
and including the taxable year ended December 31, 2019, and based on current business plans and financial projections, 
management believes there is a significant likelihood that the Company will be a PFIC during the current taxable year. If 
the Company is a PFIC for any year during a U.S. shareholder’s holding period, then such U.S. shareholder generally 
will be required to treat any gain realized upon a disposition of Common Shares, or any so-called “excess distribution” 
received  on  their  Common  Shares,  as  ordinary  income,  and  to  pay  an  interest  charge  on  a  portion  of  such  gain  or 
distributions, unless the shareholder makes a timely and effective “qualified electing fund” (“QEF Election”) or a “mark-
to-market” election with respect to the Common Shares. A U.S. shareholder who makes a QEF Election generally must 
report on a current basis its share of the net capital gain  and ordinary earnings for any year in which the Company is 
PFIC, whether or not the Company distributes any amounts to its shareholders. U.S. shareholders should be aware that 
there can be no assurance that the Company will satisfy record keeping requirements that apply to a QEF Election, or 
that the Company will supply U.S. shareholders with information that such U.S. shareholders require to report under the 
QEF Election rules, in event that the Company is a PFIC and a U.S. shareholder wishes to make a QEF Election. Thus, 
U.S. shareholders may not be able to make a QEF Election with respect to their Common Shares. A U.S. shareholder 
who  makes  the  mark-to-market  election  generally  must  include  as  ordinary  income  each  year  the  excess  of  the  fair 
market value of the Common Shares over the taxpayer’s basis therein. This paragraph is qualified in its entirety by the 
discussion below in “Item 5. Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases 
of  Equity  Securities  -  “Certain  U.S.  Federal  Income  Tax  Considerations  for  U.S.  Residents.”  Each  U.S.  shareholder 
should consult his or her own tax advisor regarding the U.S. federal, U.S. state and local, and foreign tax consequences 
of the PFIC rules and the acquisition, ownership, and disposition of Common Shares.  

The Company may experience cybersecurity threats. 

Vista  relies  on  secure  and  adequate  operations  of  information  technology  systems  in  the  conduct  of  its  operations. 
Access to and security of the information technology systems are critical to Vista’s operations. To Vista’s knowledge, it 
has  not  experienced  any  material  losses  relating  to  disruptions  to  its  information  technology  systems.  Vista  has 
implemented ongoing policies, controls and practices to manage and safeguard Vista and its stakeholders from internal 
and  external  cybersecurity  threats  and  to  comply  with  changing  legal  requirements  and  industry  practice.  Given  that 
cyber risks cannot be fully mitigated and the evolving nature of these threats, Vista cannot assure that its information 
technology systems are fully protected from cybercrime or that the systems will not be inadvertently compromised, or 
without  failures  or  defects.  Potential  disruptions  to  Vista’s  information  technology  systems,  including,  without 
limitation, security breaches, power loss, theft, computer viruses, cyber-attacks, natural disasters, and noncompliance by 
third party service providers and inadequate levels of cybersecurity expertise and safeguards of third party information 
technology service providers, may adversely affect the operations of Vista as well as present significant costs and risks 
including, without limitation, loss or disclosure of confidential, proprietary, personal or sensitive information and third 
party data, material adverse effect on its financial performance, compliance with its contractual obligations, compliance 
with  applicable  laws,  damaged  reputation,  remediation  costs,  potential  litigation,  regulatory  enforcement  proceedings 
and heightened regulatory scrutiny. 

20 

 
 
 
 
 
 
 
 
 
The Company is subject to anti-bribery and anti-corruption laws. 

Vista’s  operations  are  governed  by,  and  involve  interactions  with,  many  levels  of  government  in  numerous  countries. 
Vista is required to comply with anti-corruption and anti-bribery laws in the countries in which we conduct our business. 
In  recent  years,  there  has  been  a  general  increase  in  both  the  frequency  of  enforcement  and  the  severity  of  penalties 
under such laws, resulting in greater scrutiny and punishment to companies convicted of violating anti-corruption and 
anti-bribery laws. Furthermore, a company may be found liable for violations by not only its employees, but also by its 
contractors and third-party agents. Although we have adopted internal control policies to mitigate such risks, there can 
be  no  assurance  that  our  internal  control  policies  and  procedures  always  will  protect  us  from  recklessness,  fraudulent 
behavior,  dishonesty  or  other  inappropriate  acts  committed  by  our  affiliates,  employees  or  agents  and  such  measures 
may not always be effective in ensuring that we, our employees, contractors or third-party agents will comply strictly 
with such laws. If we find ourselves subject to an enforcement action or are found to be in violation of such laws, this 
could  lead  to civil  and  criminal  fines  and penalties,  litigation, and  loss  of operating  licenses or  permits,  resulting  in  a 
material adverse effect on our reputation and results of operations. 

Certain directors and officers may serve as directors and officers of other companies in the natural resources sector. 

While  there  are  no known  existing  or potential  conflicts of  interest between  Vista  and  any  of  its directors or officers, 
certain of the directors and officers may serve as directors and officers of other natural resource companies and therefore 
it is possible that a conflict may arise between their duties as a director or officer of Vista and their duties as a director or 
officer  of  such  other  companies.  The  directors  and  officers  of  Vista  are  aware  of  the  existence  of  laws  governing 
accountability  of  directors  and  officers  for  corporate  opportunity  and  disclosure  of  conflicts  of  interest.  Should  any 
director  or  officer  breach  the  duties  imposed  upon  them  by  applicable  laws,  such  actions  or  inactions  could  have  a 
material  adverse  effect  on  our  business  prospects,  results  of  operations,  cash  flows,  financial  condition  and  corporate 
reputation. 

Industry Risks 

Calculations of mineral reserves and mineral resources are estimates only and subject to uncertainty. 

The estimating of mineral reserves and mineral resources is an imprecise process and the accuracy of such estimates is a 
function  of  the  quantity  and  quality  of  available  data,  the  assumptions  used  and  judgments  made  in  interpreting 
engineering and geological information and estimating future capital and operating costs. There is significant uncertainty 
in any reserve or resource estimate, and the economic results of mining a mineral deposit may differ materially from the 
estimates as additional data are developed or interpretations change. 

Estimated mineral reserves and mineral resources may be materially affected by other factors. 

In addition to uncertainties inherent in estimating mineral reserves and mineral resources, other factors may adversely 
affect estimated mineral reserves and mineral resources. Such factors may include but are not limited to metallurgical, 
environmental,  permitting,  legal,  title,  taxation,  socio-economic,  marketing,  political,  gold  prices,  and  capital  and 
operating costs. Any of these or other adverse factors may reduce or eliminate estimated mineral reserves and mineral 
resources and could have a material adverse effect on our business prospects, results of operations, cash flows, financial 
condition and corporate reputation. 

Feasibility studies are estimates only and subject to uncertainty.  

Feasibility studies are used to determine the economic viability of an ore deposit, as are preliminary feasibility studies 
and  preliminary  economic  assessments.  Feasibility  studies  are  the  most  detailed  studies  and  reflect  a  higher  level  of 
confidence in the estimated production rates, and capital and operating costs. Generally accepted levels of confidence are 
plus or minus 15% for feasibility studies, plus or minus 25-30% for preliminary feasibility studies and plus or minus 35-
40% for preliminary economic assessments. These thresholds reflect the levels of confidence that exist at the time the 
study  is  completed.  Subsequent  changes  to  metal  prices,  foreign  exchange  rates  (if  applicable),  reclamation 
requirements, operating and capital costs may cause actual results of economic viability to differ materially from these 

21 

 
 
 
 
 
 
 
 
 
 
estimates. Results of subsequent Mt. Todd prefeasibility or final feasibility studies may be less favorable than the current 
study. 

Mining  companies  are  increasingly  required  to  consider  and  provide  benefits  to  the  communities  and  countries  in 
which they operate, and are subject to extensive environmental, health and safety laws and regulations.  

As a result of public concern about the real or perceived detrimental effects of economic globalization and global climate 
impacts, businesses in general and the mining industry in particular, face increasing public scrutiny of their activities. 
These businesses are under pressure to demonstrate that as they seek to generate satisfactory returns on investment to 
shareholders,  other  stakeholders,  including  employees,  governments,  indigenous  peoples,  communities  surrounding 
operations and the countries in which they operate, benefit and will continue to benefit from their commercial activities. 
The potential consequences of these pressures include reputational damage, legal suits, increased costs, increased social 
investment  obligations,  difficulty  in  acquiring  permits,  and  increased  taxes  and  royalties  payable  to  governments  and 
communities.  

Mining exploration, development and operating activities are inherently hazardous.  

Mineral exploration involves many risks that even a combination of experience, knowledge and careful evaluation may 
not be able to overcome. Operations in which we have direct or indirect interests will be subject to all the hazards and 
risks normally incidental to exploration, development and production of gold and other metals, any of which could result 
in work stoppages, damage to property, physical harm and possible environmental damage. The nature of these risks is 
such that liabilities might exceed any liability insurance policy limits. It is also possible that the liabilities and hazards 
might not be insurable, or, we could elect not to be insured against such liabilities due to high premium costs or other 
reasons,  in  which  event,  we  could  incur  significant  costs  that  could  have  a  material  adverse  effect  on  our  business 
prospects, results of operations, cash flows, financial condition and corporate reputation. 

Regulations and pending legislation involving climate change could result in increased operating costs.  

Gold  production  is  energy  intensive,  resulting  in  a  significant  carbon  footprint.  A  number  of  governments  and/or 
governmental  bodies  have  introduced  or  are  contemplating  regulatory  changes  in  response  to  various  climate  change 
interest groups and the potential impact of climate change. This type of legislation and possible future legislation and 
increased regulation regarding climate change could impose significant costs related to increased energy requirements, 
capital equipment, environmental monitoring and reporting and other costs to comply with such regulations. 

22 

 
 
 
 
 
 
 
Pending initiatives involving taxation could result in increased tax and operating costs.  

There  is  growing  attention  from  the  media  and  the  public  on  perceived  international  tax  avoidance  techniques  which 
could  result  in  escalating  rates  of  poverty,  inequality  and  unemployment  in  host  countries.  Initiatives  like  the  Base 
Erosion and Profit Shifting project being led by the Organization for Economic Cooperation and Development aim  to 
reform  the  system  of  international  taxation  to  minimize  international  tax  avoidance  techniques.  This  initiative  and 
possible future initiatives could result in increased tax expense and related compliance costs for Mt Todd or other future 
mining operations. 

Newly  adopted  rules  regarding  mining  property  disclosure  by  companies  reporting  with  the  SEC  may  result  in 
increased operating and legal costs. 

On October 31, 2018, the SEC adopted new rules to modernize mining property disclosure in reports filed with the SEC 
in order to harmonize SEC disclosure requirements with international standards. These rules are not effective until the 
Company’s first full fiscal year beginning on or after January 1, 2021. The Company currently reports mineral resources 
and reserves in compliance with NI 43-101. Because the Company files its reports with the SEC on U.S. domestic forms, 
under  the  new  rules,  the  Company  will  be  required  to  comply  with  the  new  SEC  mining  property  disclosure 
requirements and not make disclosure in accordance with NI 43-101 in the reports it files with the SEC. It is not clear at 
this time if the Company will be required to prepare separate technical reports under the two reporting regimes or may 
rely on one technical report prepared in accordance with both reporting standards. Further, while the Company currently 
utilized its reports as filed with the SEC in meeting its reporting obligations in Canada, if its future reports have mining 
property  disclosure  that  is  not  NI  43-101  compliant,  the  Company  may  have  to  prepare  separate  reports  or  a 
supplemental NI 43-101 mining property report. All these changes to the Company’s reporting requirements could result 
in increased compliance costs.

ITEM 2. PROPERTIES.  

The  following  scientific  and  technical  disclosures  about  Mt  Todd  have  been  reviewed  and  approved  by  Mr.  John  W. 
Rozelle, Senior Vice President of Vista. Mr. Rozelle is a qualified person as defined by NI 43-101. 

All dollar amounts in ITEM 2. are in U.S. dollars and thousands, unless otherwise indicated. 

Cautionary Note to Investors:  This section and other sections of this annual report on Form 10-K contain the terms 
“measured mineral resources,” “indicated mineral resources,” “inferred mineral resources,” “proven mineral reserves,” 
and  “probable  mineral  reserves”  as  defined  in  accordance  with  NI 43-101.  Please  note  the  following  regarding 
these terms: 

 

 

“Measured  mineral  resources”  and  “indicated  mineral  resources”  –  We  advise  investors  that  although 
these terms are recognized and required by Canadian regulations, these terms are not defined in SEC Industry 
Guide 7 and the SEC does not normally permit such terms to be used in reports and registration statements filed 
with  the  SEC.  Investors  are  cautioned  not  to  assume  that  any  part  or  all  of  the  mineral  deposits  in  these 
categories will ever be converted into reserves. 

“Inferred  mineral  resources”  –  We  advise  investors  that  although  this  term  is  recognized  by  Canadian 
regulations, the SEC does not recognize it. “Inferred mineral resources” have a great amount of uncertainty as 
to  their  existence,  and  great  uncertainty  as  to  their  economic,  technical  and  legal  feasibility.  It  cannot  be 
assumed that all or any part of an inferred mineral resource will ever be upgraded to a higher category. Under 
Canadian  rules,  estimates  of  inferred  mineral  resources  may  not  form  the  basis  of  a  feasibility  study  or 
preliminary  feasibility  study,  except  in  rare  cases.  The  SEC  normally  only  permits  an  issuer  to  report 
mineralization  that  does  not  constitute  “reserves”  as  in-place  tonnage  and  grade  without  reference  to  unit 
measures. Investors are cautioned not to assume that any part or all of an inferred mineral resource exists or is 
economically or legally minable. 

 

“Proven  mineral  reserves”  and  “probable  mineral  reserves”  –  The  definitions  of  proven  and  probable 
mineral reserves used in NI 43-101 differ from the definitions for “proven reserves” and “probable reserves” as 
found in SEC Industry Guide 7. Accordingly, our disclosures of mineral reserves herein may not be comparable 
to information from U.S. companies subject to reporting and disclosure requirements of the SEC. 

Cautionary  Note  To  All  Investors  Concerning  Economic  Assessments  That  Include Mineral  Resources:  Mineral 
resources that are not mineral reserves have no demonstrated economic viability.

Mt Todd Gold Project, Northern Territory, Australia 

Current Technical Report 

The 2019 PFS for Mt Todd pursuant to NI 43-101 was filed on SEDAR on October 7, 2019 and furnished on EDGAR 
on  October  15,  2019  and  is  entitled  “NI  43-101  Technical  Report  -  Mt  Todd  Gold  Project  -  50,000  tpd  Preliminary 
Feasibility  Study  –  Northern  Territory,  Australia”  with  an  effective  date  of  September  10,  2019  and  an  issue  date  of 
October  7,  2019  prepared  by  Rex  Clair  Bryan,  Ph.D.,  Anthony  Clark,  P.E.,  Thomas  L.  Dyer,  P.E.,  Amy  L.  Hudson, 
Ph.D., CPG, REM, Chris Johns, M.Sc., P.Eng., Deepak Malhotra, Ph.D., Zvon Ponos, BE, MIEAust, CPeng, NER, Guy 
Roemer,  P.E., Vicki  J.  Scharnhorst,  P.E.,  LEED  AP,  Jessica  I.  (Spriet) Monasterio,  P.E.,  Keith  Thompson,  CPG,  PG, 
each of whom is a qualified person under NI 43-101. 

The following description of Mt Todd has been sourced, in part, from the 2019 PFS and readers should consult the 2019 
PFS  to  obtain  further  particulars  regarding  Mt  Todd.  The  2019  PFS  is  available  for  review  under  our  profile  at 
www.sedar.com and www.sec.gov. The 2019 PFS is not incorporated by reference into this annual report on Form 10-K. 

Certain capitalized terms in this section not otherwise defined have the meanings ascribed to them in the 2019 PFS.  

Preliminary Feasibility Study Results: Base Case  

The  2019  PFS  successfully  confirmed  the  efficiency  of  ore  sorting  across  a  broad  range  of  head  grades,  the  natural 
concentration  of  gold  in  the  screen  undersize  material  prior  to  sorting,  the  efficiency  of  fine  grinding  and  the  resulting 
improved gold recoveries at a final grind size of P80 40 µm, and the selection of FLSmidth’s VXP mill as the preferred fine 
grinding mill. The 2019 PFS incorporates these changes and evaluates two development scenarios: a 50,000 tpd project that 
develops more of the Mt Todd resource and generates a larger net present value (“NPV”) (the “Base Case”); and a smaller 
and higher-grade 33,000 tpd project (the “Alternate Case”). The Alternate Case as presented in the 2019 PFS supersedes a 
similar alternate case presented in the 2018 PFS. The 2019 Alternate Case is not deemed material in light of the superior 
economics demonstrated by the 2019 Base Case.  

The Base Case (50,000 tpd) includes: 

  Estimated proven and probable mineral reserves of 5.848 Moz of gold (221 Mt at 0.82 g Au/t) at a cut-off 

grade of 0.40 g Au/t(1)(2); 

  Average  annual  production  of  413,400  ounces  of  gold  over  the  mine  life,  including  average  annual 
production of 495,100 ounces of gold per year during the first five years of operations  excluding ramp-up 
and commissioning; 

  Life of Mine average cash costs of $645 per ounce, including average cash costs of $575 per ounce during 

the first five years of operations (excluding ramp-up and commissioning); 

  A 13-year operating life; 

  After-tax  NPV5%  of  $823  million  and  internal  rate  of  return  (“IRR”)  of  23.4%  at  a  price  of  $1,350  per 

ounce of gold and a AUD:USD exchange rate of 0.70, and 

 

Initial capital requirements of $826 million. 

(1)  Cautionary  note  to  investors:  Proven  and  probable  mineral  reserves  are  estimated  in  accordance  with  NI  43-101  and  do  not 
constitute SEC Industry Guide 7 compliant reserves. See the section heading “Cautionary Note to Investors Regarding Estimates 
of Measured, Indicated and Inferred Resources and Proven and Probable Mineral Reserves” above.

Note: Amounts may not add due to rounding. Asset sale and salvage value assumptions include end of life re-sale values for mining 
and processing equipment; and recycle value for steel and pipe from the process plant and other facilities. We assume the power plant 
will be sold as a going concern.  

(1) Net of asset sales.  

The Base Case includes a 70MW gas-fired power plant in the initial capital. The Project consumes all power generated 
during the operating life. Self-generated power creates significant savings in operating costs compared to grid-sourced 
power. During the four years of reclamation and closure, the 2019 PFS assumes we will continue to generate ~20MW of 
power and sell that power into the NT electrical grid, for which there is a known market and indicative purchase rates 
have been provided by the government-owned utility.

The  life  of  mine  production  schedule  contemplates  221.0  million  tonnes  of  ore  containing  an  estimated  5.85  million 
ounces  of  gold  at  an  average  grade  of  0.82  g  Au/t  to  be  processed  over  a  13-year  operating  life  of  the  Project.  Total 
recovered  gold  is  expected  to  be  5.3  million  ounces.  Average  annual  gold  production  over  the  life  of  the  Project  is 
expected  to  be  413,400  ounces,  averaging  495,100  ounces  during  the  first  five  years  of  commercial  operations. 
Commercial  production  is  anticipated  to  begin  after  two  years  of  construction  and  six  months  of  commissioning  and 
ramp-up.

Property Description, Location and Access 

In 2006, through an agreement with the Deed Administrators for Pegasus Gold Australia Pty. Ltd. (“Pegasus”), the NT 
Government  and  the  Jawoyn  Association  Aboriginal  Corporation  (“JAAC”),  we  acquired  the  concession  rights  and 
access  to  Mt  Todd.  Also  in  2006,  through  an  agreement  with  the  NT  Government,  we  established  the  rights  and

obligations of both parties with respect to Mt Todd site care and maintenance and potential future development. In 2017, 
the latter agreement was extended through the end of 2023.  

Mt Todd was an operating mine in the mid-1990s, but the project had been closed due to bankruptcy and was held by 
these organizations. The failure of the project was primarily a result of inefficiencies in the comminution circuit, poor 
gold recoveries and low gold prices. We hold Mt Todd through our wholly-owned subsidiary Vista Gold Australia Pty. 
Ltd. (“Vista Gold Australia”). 

Mt Todd is located 56 kilometers by road northwest of Katherine, NT, Australia, and approximately 290 kilometers by 
road southeast of Darwin. Access is by existing paved public roads and approximately four kilometers of paved private 
road. We control and maintain the private paved road. 

Total land holdings controlled by Vista Gold Australia are approximately 160,000 hectares. A map showing the location 
of the mineral licenses (“MLs”) and exploration licenses (“ELs”) and a table with a list of MLs and ELs and the holding 
requirements are set out below. All of the estimated mineral resources are located within the boundaries of the MLs and 
substantially all of the estimated mineral resources at Mt Todd are located in the Batman deposit.  

Gold  mineralization  in  the  Batman  deposit  occurs  in  sheeted  veins  within  silicified  greywackes/shales/siltstones.  The 
Batman  deposit  strikes  north-northeast  and  dips  steeply  to  the  east.  Higher  grade  zones  of  the  deposit  plunge  to  the 
south.  The  core  zone  is  approximately  200-250  meters  wide  and  1.5  kilometers  long,  with  several  hanging  wall 
structures providing additional width to the orebody. Mineralization is open at depth as well as along strike, although the 
intensity of mineralization weakens to the north and south along strike. 

The  Mt  Todd  Base  Case  is  designed  to  be  a  large  open-pit  mining  operation  that  will  utilize  large-scale  mining 
equipment  in  a  drill/blast/load/haul  operation.  Ore  is  planned  to  be  processed  in  a  comminution  circuit  consisting  of 
large-scale  equipment,  including:  a  gyratory  crusher,  cone  crushers,  high  pressure  grinding  roll  (“HPGR”)  crushers 
followed by X-ray transmission (“XRT”) and laser sorting, and primary ball mills, followed by VXP Mills, as discussed 
in greater detail below. Vista plans to recover gold in a conventional carbon-in-pulp (“CIP”) recovery circuit. 

The  Mt  Todd  site  was  not  reclaimed  when  the  mine  closed  in  the  late  1990s.  Liability  for  the  reclamation  of  the 
environmental conditions existing prior to Vista’s involvement remains the responsibility of the NT Government until 
we have provided notice to the NT Government that we intend to take over and assume the management, operation, and 
rehabilitation of Mt Todd. Vista does not plan to give such notice until a production decision has been made, the Project 
is fully permitted to construct the mine, and the necessary construction financing has been arranged.  

The  area  has  a  sub-tropical  climate  with  a  distinct  wet  season  and  dry  season.  The  area  receives  most  of  its  rainfall 
between  the  months  of  January  and  March.  Temperatures  are  moderate,  allowing  for  year-round  mining  operations. 
Topography  is  relatively  flat.  The  tenements  encompass  a  variety  of  habitats  forming  part  of  the  northern  Savannah 
woodland region, which is characterized by eucalypt woodland with tropical grass understories. Surface elevations are 
approximately 130 to 160 meters above sea level in the area of the previous and planned plant site and waste dump. 

The Batman and Quigleys deposits are located within the MLs. Should a deposit be discovered on the ELs, the portion of 
the related EL would have to be converted to an ML before mining operations could start.

The surface land in the area of the contiguous MLs and ELs (excluding EL 28321) is freehold land owned by the JAAC. 
Because the JAAC have title to the land, such land is not part of the lands classified by the government as indigenous 
lands, and as a result such lands are not subject to an Indigenous Land Use Agreement. Vista has a private agreement 
with the JAAC for access to the land. 

Under the terms of our agreement with the JAAC, we must offer the JAAC the opportunity to establish a joint venture 
with Vista holding 90% and the JAAC holding a 10% participating interest in Mt Todd. In addition, the JAAC will be 
entitled to cash payments, or payment in kind, equal to 1% of the value of the annual gold production from the current 
MLs, and a 1% net smelter return royalty (“NSR”) on other metals, subject to a minimum payment of A$50 per year. 

We are required annually to submit an MMP to the DPIR that details work to be done on the property. We have received 
approval for all work done on the Project to date and obtained approval for the EIS. Further permitting will be required

before mine development can start. The related permitting processes are relatively straight-forward and are not expected 
to  impede,  to  a  material  extent,  our  exploration  and  future  development  plans.  Any  future  mining  will  require  an 
approved closure plan and sufficient surety bonding to fund that closure.  

Following the bankruptcy of the previous operator, most of the processing equipment and facilities were removed from 
the  site;  but  some  basic  infrastructure  which  may  be  of  use  in  a  future  operation  is  still  in  place,  including  a  fully 
functioning  tailings  impoundment  facility  that  has  capacity  to  store  additional  mill  tailings  and  a  fresh  water  storage 
reservoir. In addition, a medium voltage power line supplies the site with electrical power, and a natural gas pipeline, 
used for power generation by the former operators, is still in place. Mt Todd is located sufficiently close to the city of 
Katherine and the town of Pine Creek to allow for an easy commute for workers.  

Because the Mt Todd site was not reclaimed when the mine closed, the dumps and heap leach pad require ongoing care 
and maintenance, which we provide. Precipitation on the waste dumps, low-grade ore stockpiles and scats have resulted 
in acid rock drainage which is managed through collection in retention ponds, storage, pH adjustment followed by the 
controlled release of treated water into the Edith River, in accordance with the Waste Discharge License (“WDL”).  

History 

The Batman gold prospect is located in the Pine Creek Geosyncline goldfield that was worked from early in the 20th 
century. Gold and tin were discovered in the Mt Todd area in 1889. Most deposits were worked in the period from 1902 
to 1914. A total of 7.80 tonnes of tin concentrate was obtained from cassiterite-bearing quartz-kaolin lodes at the Morris 
and Shamrock mines. The Jones Brothers reef was the most extensively mined gold-bearing quartz vein, with a recorded 
production  of  28.45  kg  Au.  This  reef  consists  of  a  steeply  dipping  ferruginous  quartz  lode  within  tightly  folded 
greywackes. 

The Yinberrie Wolfram field, discovered in 1913, is located 5 kilometers west of Mt Todd. Tungsten, molybdenum and 
bismuth  mineralization  was  discovered  in  greisenized  aplite  dykes  and  quartz  veins  in  a  small  stock  of  the  Cullen 
Batholith. Recorded production from numerous shallow shafts is 163 tonnes of tungsten, 130 kg of molybdenite and a 
small quantity of bismuth. 

Exploration for uranium began in the 1950s. Small uranium prospects were discovered in sheared or greisenized portions 
of the Cullen Batholith in the vicinity of the Edith River.  

Australian  Ores  and  Minerals  Limited  (“AOM”)  in  a  joint  venture  with  Wandaroo  Mining  Corporation  and  Esso 
Standard Oil took out a number of mining leases in the Mt Todd area during 1975. Initial exploration consisted of stream 
sediment  sampling,  rock  chip  sampling,  and  geological  reconnaissance  for  a  variety  of  commodities.  A  number  of 
geochemical anomalies were found primarily in the vicinity of old workings. Follow-up work concentrated on alluvial 
tin  and,  later,  auriferous  reefs.  Backhoe  trenching,  costeaning,  and  ground  follow-up  were  the  favored  mode  of 
exploration. Two diamond drillholes were drilled at Quigleys. Despite determining that the gold potential of the reefs in 
the area was promising, AOM ceased work around Mt Todd. 

The  Arafura  Mining  Corporation,  CRA  Exploration,  and  Marriaz  Pty  Ltd  all  explored  the  Mt  Todd  area  at  different 
times  between  1975  and  1983.  In  late  1981,  CRA  Exploration  conducted  grid  surveys,  geological  mapping  and  a  14 
diamond  drillhole  program,  with  an  aggregate  meterage  of  676.5  m,  to  test  the  gold  content  of  Quigleys  Reef  over  a 
strike length of 800 meters. Following this program CRA Exploration did not proceed with further exploration. 

During  late  1986,  Pacific  Gold  Mines  NL  (“Pacific”)  undertook  exploration  in  the  area  which  resulted  in  small-scale 
open cut mining on the Quigleys and Golf reefs, and limited test mining at the Alpha, Bravo, Charlie and Delta pits. Ore 
was  transported  to  a  CIP  plant  owned  by  Pacific  at  Moline.  This  continued  until  December  1987.  Pacific  ceased 
operations  in  the  area  in  February  1988  having  produced  approximately  86,000  tonnes  grading  4  g  Au/t  (historic 
reported  production,  not  NI  43-101  compliant).  Subsequent  negotiations  between  the  joint  venture  partners  Shell 
Company of Australia (“Billiton”), Zapopan NL (“Zapopan”) and Pacific resulted in the acquisition of this ground and 
incorporation into the joint venture. 

32 

  
 
 
 
 
 
 
 
 
 
Billiton, who was the managing partner in an exploration program in the joint venture with Zapopan, discovered the Mt 
Todd mineralization, or more specifically the Batman deposit, in May 1988. In 1992, Pegasus Gold Australia Pty. Ltd. 
(“Pegasus”)  acquired  a  share  holding  in  Zapopan,  following  which  Zapopoan  acquired  Billiton’s  interest.  Pegasus 
progressively increased their shareholding until they acquired full ownership of Zapopan in July 1995. 

Feasibility studies (not NI 43-101 compliant) for Phase I, a heap leach operation which focused predominately on the 
oxide  portion  of  the  deposit,  commenced  during  1992  culminating  in  an  engineering,  procurement,  construction 
management  (“EPCM”)  award  to  Minproc  in  November  of  that  year.  The  Phase  I  project  was  predicated  upon  a  4 
million  tonne  per  year  (“Mtpy”)  heap  leach  plant,  which  came  on  stream  in  late  1993.  The  treatment  rate  was 
subsequently expanded to a rate of 6 Mtpy in late 1994.

Phase  II  involved  expanding  to  8  Mtpy  and  treatment  through  a  flotation  and  carbon-in-leach  circuit.  The  feasibility 
study  was  conducted  by  a  joint  venture  between  Bateman  Kinhill  and  Kilborne  (“BKK”)  and  was  completed  in  June 
1995. 

The Pegasus board approved the project on August 17, 1995, and awarded an EPCM contract to BKK in October 1995. 
Commissioning  commenced  in  November  1996.  Final  capital  costs  to  complete  the  project  were  AUD232  million 
(USD181 million). 

Design capacity was never achieved due to inadequacies in the 3rd and 4th stages of the crushing circuit. A throughput 
rate  of  just  under  7  Mtpy  was  achieved  by  mid-1997;  however,  problems  with  the  flotation  circuit  which  resulted  in 
reduced recoveries necessitated closure of this circuit. Subsequently, high reagent consumption, as a result of cyanide 
soluble copper minerals, further hindered efforts to reach design production. Operating costs were above those predicted 
in  the  feasibility  study.  The  spot  price  of  gold  deteriorated  from  above  USD400  in  early  1996  to  below  USD300  per 
ounce  at  the  end of  1997.  This,  combined with  underperformance  of  the  project  and higher operating  costs  led  to  the 
mine being closed and placed on care and maintenance on November 14, 1997. 

In  February  1999,  General  Gold  Resources  Pty.  Ltd.  (“General  Gold”)  agreed  to  form  a  joint  venture  with  Multiplex 
Resources Pty Ltd (“Multiplex”) and Pegasus to own, operate, and explore the mine. Initial equity participation in the 
joint venture was General Gold 2%, Multiplex 93%, and Pegasus 5%. The joint venture appointed General Gold as mine 
operator, which contributed the operating plan in exchange for a 50% share of the net cash flow generated by the project, 
after allowing for acquisition costs and environmental sinking fund contributions. General Gold operated the mine from 
March  1999  to  July  2000.  Operations  ceased  in  July  2000,  and  Pegasus,  through  the  Deed  Administrators,  regained 
possession of various parts of the mine assets in order to recoup the balance of purchase price owed to it. Most of the 
equipment was sold in June 2001 and removed from the mine.  

33 

 
 
 
 
 
 
 
In March 2006, Vista acquired the concession rights from the Deed Administrators, surface rights from the JAAC and 
entered into a contract with the Government of the Northern Territory of Australia. 

Geological Setting, Mineralization, and Deposit Type 

Mt Todd is situated within the southeastern portion of the Early Proterozoic Pine Creek Geosyncline. Meta-sediments, 
granitites, basic intrusives, acidic and intermediate volcanic rocks occur within this geological province. Within the Mt 
Todd region, the oldest outcropping rocks are assigned to the Burrell Creek Formation. These rocks consist primarily of 
interbedded greywackes, siltstones, and shales of turbidite affinity, which are interspersed with the minor volcanics. The 
Burrell  Creek  Formation  is  overlain  by  interbedded  greywackes,  mudstones,  tuffs,  minor  conglomerates,  mafic  to 
intermediate volcanics and banded ironstone of the Tollis Formation. The Burrell Creek Formation and Tollis Formation 
comprise  the  Finniss  River  Group.  The  Finniss  River  Group  strata  have  been  folded  about  northerly  trending  F1  fold 
axes.  The  folds  are  closed  to  open  style  and  have  moderate  westerly  dipping  axial  planes  with  some  sections  being 
overturned.  A  later  north-south  compression  event  resulted  in  east-west  trending  open  style  upright  D2  folds.  The 
Finniss  River Group  has  been regionally  metamorphosed to  lower  green  schist facies. Late  and  Post Orogenic granite 
intrusions of the Cullen Batholith occurred from 1,789 Ma to 1,730 Ma, and brought about local contact metamorphism 
to hornblende hornfels facies.  

The Batman pit geology consists of a sequence of hornfelsed interbedded greywackes and shales with minor thin beds of 
felsic  tuff.  Bedding  consistently  strikes  at  325  degrees,  dipping  40  degrees  to  60  degrees  to  the  southwest.  Northerly 
trending sheeted quartz sulfide veins and joints striking at 0 degrees to 20 degrees and dipping 60 degrees to the east are 
the major controls for mineralization in the Batman pit. The veins are 1 to 100 millimeters in thickness with an average 
thickness of around 8 to 10 millimeters and occur in sheets with up to 20 veins per horizontal meter. These sheeted veins 
are the main source of gold mineralization in the Batman pit. In general, the Batman pit extends 1,600 meters in length 
by 1,100 meters in width and has been drill tested to a depth of 800 meters down-dip. The deposit is open along strike 
and at depth.  

The  mineralization  within  the  Batman  pit  is  directly  related  to  the  intensity  of  the  north-south  trending  quartz  sulfide 
veining. The lithological units impact on the orientation and intensity of mineralization. Sulfide minerals associated with 
the gold mineralization are pyrite, pyrrhotite and lesser amounts of chalcopyrite, bismuthinite and arsenopyrite. Galena 
and sphalerite are also present, but appear to be post-gold mineralization, and are related to calcite veining in the bedding 
plains and the east-west trending faults and joints. Two main styles of mineralization have been identified in the Batman 
pit. These are the north-south trending vein mineralization and bedding parallel mineralization.  

Based  on  our  review  of  the  historic  project  files,  we  believe  that  approximately  21.4 million  tonnes  grading  1.05 
grams gold per tonne and containing 723,795 ounces of gold were extracted between 1993 and the termination of mining 
in 2000. Processing was by a combination of heap leach production from oxide ore and cyanidation of sulfide ore. The 
remaining mineralization consists of sulfide mineralization lying below and along strike of the existing open pit, and in 
hanging wall structures parallel to the main zone in the existing open pit. 

Exploration Licenses 

Since  acquiring  the  Mt  Todd  ELs,  Vista  has  conducted  an  ongoing  exploration  program  that  includes  prospecting, 
geologic mapping, rock and soil sampling, geophysical surveys and exploration drilling. Equipment and personnel were 
mobilized  from  the  site  or  from  an  exploration  base  camp  established  in  the  central  part  of  the  ELs.  The  work  was 
conducted by geologists and field technicians. 

The exploration effort initially focused on follow up work on targets developed by Pegasus during their tenure on the 
property.  These  included  the  RKD  target,  Tablelands,  and  Silver  Spray.  During  a  review  of  Pegasus’  airborne 
geophysical survey data, five distinct magnetic highs were observed located within sedimentary rocks that should have a 
low  magnetic  signature.  These  features  are  similar  to  those  at  Batman,  which,  as  a  result  of  the  included  pyrrhotite, 
exhibits a strong magnetic high. The geophysical targets were prioritized following review of historic work in the area 

34 

 
 
 
 
 
 
 
 
 
and site visits. To date, two of the geophysical targets, Golden Eye and Snowdrop, have been drilled and a third, Black 
Hill, has been covered by soil sampling.  

The  Wandie  target  has  a  different  magnetic  signature.  Field  examination  identified  small  scale  pits  on  an  iron-rich 
outcropping.  

There  are no  reportable resources  and reserves  on  the  ELs. No data from  the  ELs  are  used  in  the development  of  the 
2019 PFS results.

Based  on  airborne  geophysical  survey  data,  we  have  identified  several  magnetic  targets  within  our  controlled  land 
holdings  surrounding  the  Batman  pit.  The  targets  are  distinct  magnetic  highs  located  within  sedimentary  rocks  that 
should have a low magnetic signature. These features are similar to those at Mt Todd, which, as a result of the included 
pyrrhotite, exhibits a strong magnetic high.  

Mineralization  at  the  Quigleys  deposit  is  interpreted  to  occur  within  a  series  of  mineralized  shears  that  strike  north 
northwest and dip 30 to 35 degrees to the west. The main shear extends for nearly one kilometer along the strike and has 
been drilled to a vertical depth of 230 meters. The mineral resource estimate has been defined by 632 drill holes drilled 
by  Pegasus  and  Billiton  Australia  Gold  Pty.  Ltd.  in  the  late  1980s  through  the  mid-1990s.  Tetra  Tech  reviewed  the 
integrity  of  the  drill-hole  database  and  developed  a  computer  model  to  estimate  and  classify  the  estimated  mineral 
resources.  The  model  reflected  Tetra  Tech’s  geological  interpretation  of  the  deposit,  which  constrained  the 
mineralization  to  the  shear  zones  using  geological  information  and  assays  from  49,178  samples  obtained  from  the 
drilling.  Lower  grade,  erratic  mineralization  in  the  hanging  wall  of  the  shears  has  not  been  included  in  the  mineral 
resource estimate. 

Sampling and assaying was done under the supervision of prior operators in conjunction with evaluation of the Batman 
pit and are discussed in the 2019 PFS, as part of the overall Project sampling and assaying methodology.  

Based on Tetra Tech’s resource analysis, at a cut-off grade of 0.40 g Au/t, measured mineral resources are estimated at 
457,000 tonnes grading 1.27 g Au/t, indicated mineral resources are estimated at 5.7 million tonnes grading 1.12 g Au/t 
and inferred mineral resources are estimated at 1.6 million tonnes grading 0.84 g Au/t. Cautionary Note to Investors: see

Batman Deposit Drilling 

The Batman deposit resource drillhole database consists of both pre-Vista and Vista drill holes.  All of the Vista resource 
drill holes are HQ-size core holes.  Vista has drilled a total of 92 HQ diamond drill holes totaling 58,863 meters.  All of 
the Vista diamond drill core samples were sawn into half splits for assaying purposes. 

The pre-2007 exploration database (pre-Vista) consists of 743 drill holes, of which 226 are diamond drill holes and 517 
are percussion drill holes.  These drill holes total approximately 98,000 meters.  The diamond core was a combination of 
NQ and HQ sizes, with the NQ core being sawed into half splits and the HQ core being sawed into quarter splits.   

There  has  been  no  additional  resource  drilling  since  the  issuance  of  the  2018  PFS.  The  2019  PFS  utilizes  the  same 
resource model as the 2018 PFS. 

Sampling, Analysis and Data Verification 

The sampling method and approach for drillholes completed between 2012 and 2018 has remained consistent. The drill 
core, upon removal from the core barrel, is placed into plastic core boxes. The plastic core boxes are transported to the 
sample  preparation  building where  the  core  is  marked, geologically  logged, geotechnically  logged, photographed,  and 
cut into halves. One-half is placed into sample bags as nominal one-meter sample lengths, and the other half retained for 
future  reference.  The  only  exception  to  this  is  when  a  portion  of  the  remaining  core  has  been  flagged  for  use  in  the 
ongoing metallurgical testwork. 

The bagged samples have sample tags placed both inside and on the outside of the sample bags. The individual samples 
are grouped into “lots” for submission to Northern Analytical Laboratories for preparation and analytical testing. All of 
this work was done under the supervision of a Vista geologist. 

The following section describes the sample preparation, analyses and security undertaken by Vista through the March 
2018 resource update. 

The diamond drilling program was conducted under the supervision of the geologic staff composed of a chief geologist, 
several experienced geologists, and a core handling/cutting crew. The core handling crew was recruited locally. 

Facilities  for  the  core  processing  included  an  enclosed  logging  shed  and  a  covered  cutting  and  storage  area  that  was 
fenced  in.  Both  of  these  facilities  were  considered  to be  limited  access areas  and kept  secured when  work  was not  in 
progress. 

The diamond drill core was boxed and stacked at the rig by the drill crews. Core was then picked up daily by members 
of the core handling crew and transported directly into the logging shed. Processing of the core included photographing, 
geotechnical  and  geologic  logging,  and  marking  the  core  for  sampling.  The  nominal  sample  interval  was  one  meter. 
When  this  process  was  completed,  the  core  was  moved  into  the  core  cutting/storage  area  where  it  was  laid  out  for 
sampling. The core was logged using the following procedures: 

  One-meter depth intervals were marked out on the core by a member of the geologic staff; 
  Core orientation (bottom of core) was marked with a solid line when at least three orientation marks aligned 
and used for structural measurements. When orientation marks were insufficient an estimation orientation was 
indicated by a dashed line; 

  Geologic logging was then done by a member of the geologic staff. Assay intervals were selected at that time 
and a cut line marked on the core. The standard sample interval was one-m, with a minimum of 0.4 meters and 
a maximum of 1.4 meters; 

  Blind  sample  numbers  were  then  assigned  based  on  pre-labeled  sample  bags.  Sample  intervals  were  then 

indicated in the core tray at the appropriate locations; 

36 

 
 
 
 
 
 
 
 
 
 
 
 
  Each  core  tray  was  photographed  and  restacked  on  pallets  pending  sample  cutting  and  stored  on  site 

 

indefinitely; and 
9,635 assays were added for the October 2012 resource update, an additional 7,601 assay intervals were added 
for the March 2013 resource, and 729 assay intervals were added for the 2017 model update. 

The  core  was  then  cut  using  diamond  saws  with  each  interval  placed  in  sample  bags.  At  this  time,  the  standards  and 
blanks were also placed in plastic bags for inclusion in the shipment. A reference standard or a blank was inserted at a 
minimum ratio of 1 in 10 and at suspected high-grade intervals additional blanks sample were added. Standard reference 
material was sourced from Ore Research & Exploration Pty Ltd and provided in 60 g sealed packets. When a sequence 
of five samples was completed, they were placed in a shipping bag and closed with a zip tie. All of these samples were 
kept in the secure area until crated for shipping. 

Samples  were  placed  in  crates  for  shipping  with  100  samples  per  crate  (20  shipping  bags).  The  crates  were  stacked 
outside the core shed until picked up for transport.

sample preparation. After preparation, samples were then forwarded on to ALS in Malaga, Western Australia for assay 
analyses. One in every 20 pulp or reject was sent from ALS in Alice Springs to Northern Australian Laboratories (NAL), 
Vista was notified by email which samples were sent to NAL. For the 2011-2012 drilling campaign samples for assay 
were  sent  to  NAL  lab  in  Pine  Creek,  NT.  Check  assays  on  one  in  every  20  pulps  or  rejects  were  completed  by  NT 
Environmental Laboratories. Following completion of assay results, all pulps and reject material was shipped back to the 
Project site and stored. 

Vista is completely independent of each of the above listed analytical testing entities, other than the engagement of said 
entities as a service provider. 

Sample Security 

NAL is the primary laboratory we use for analysis of drill core assays. The NAL laboratory is located in the town of Pine 
Creek, approximately 50 kilometers distant by road from the Project site. Samples were picked up and transported by 
NAL employees. 

37 

 
 
 
 
 
 
 
 
 
 
Sample shipments were scheduled for approximately once a week. The sealed crates were picked up on site by NAL for 
direct road transport to the assay lab. A sample transmittal form was prepared and included with each shipment and a 
copy was filed in the geology office on site. 

When the shipment left site, sample transmittals were prepared and e-mailed to NAL. When the shipment arrived at the 
preparation facility the samples were lined out and a confirmation of sample receipt was e-mailed back to Vista. 

Statistical  analyses  of  the  various  drilling  populations  and  quality  assurance/quality  control  (QA/QC)  samples  have 
neither  identified  nor  highlighted  any  reasons  to  not  accept  the  data  as  representative  of  the  tenor  and  grade  of  the 
mineralization estimated at the Batman deposit. 

Mineral Resources and Mineral Reserve Estimates 

The table below illustrates the updated mineral reserve and resource estimate for the project. The effective date of the

Batman mineral reserves are reported using a  0.40 cut-off grade and a $1,250 per ounce gold price. Unit costs used: $1.90/tonne 
mined, milling cost $7.80/tonne processed, tailings cost $0.90 per tonne processed, G&A cost $0.46/tonne processed, water treatment 
$0.10/tonne processed, 1% gross royalty. Ore processing at 50,000 TPD, 355 Days/Yr., for a total of 17,750,000 TPY. Au recovery: 
sulfide 85%, transition 80%, oxide 80%. Because all of the heap-leach pad reserves are to be fed through the mill, these reserves are 
reported without a cutoff grade applied.

any of which may result in a reduction or elimination of reported mineral reserves and mineral resources. See “Item 
1A. Risk Factors.” 

The tables below show the resource classification criteria and variogram parameters for the Batman resource model. 

Mining Operations 

Only  open-pit  mining  methods  are  considered  for  mining  at  Mt  Todd.  Mt  Todd  has  been  planned  as  a  conventional, 
owner-operated,  truck  and  shovel  operation,  that  will  use  large-scale  mining  equipment  in  a  drill/blast/load/haul 
operation. The truck and shovel method provides reasonable cost benefits and selectivity for this type of deposit.  

39 

 
 
 
 
 
 
 
 
 
Mineral Processing  

The  flowsheet  consists  of  open-circuit  primary  crushing,  closed-circuit  secondary  crushing,  closed-circuit  tertiary 
crushing using HPGR crushers, ore sorting, two-stage grinding, cyclone classification, pre-leach thickening, leach and 
adsorption, elution electrowinning and smelting, carbon regeneration, tailings detoxification and disposal to conventional 
tailings storage facility (“TSF”). The flowsheet for the Base Case is illustrated below. 

Metallurgical Testing 

Our metallurgical test work programs have confirmed: (1) ore hardness estimates at the Batman deposit are consistent 
throughout  the  deposit  and  do  not  change  at  depth;  (2)  the  selection  of  HPGR  crusher  technology  as  part  of  the 
comminution circuit; (3) the selection of ore sorting technology to eliminate low-grade material after crushing and prior 
to grinding; (4) estimated gold recovery rates based on optimized grind size and leach conditions; and (5) the processing 
of material from the historic heap leach pad at the end of the proposed mine life. 

The test work results collated from the 2011 and 2012 testing campaigns and additional metallurgical and process test 
work  conducted  in  2016,  2017,  2018,  and  2019,  together  with  the  process  design  criteria,  were  used  to  develop  the 
process flow sheet and mass balance. 

40 

 
 
 
 
 
 
 
Ore Hardness 

Bond  ball  mill  work  indices  (“BWi”)  were  determined  at  a  grind  size  of  P80  of  100  mesh  for  the  various  products, 
namely HPGR crusher, ore-sorting, composite samples and waste material.  

The test results indicate the following: 

  The BWi for the ore sorter feed (plus 5/8” screened HPGR crusher product) was higher than the composite 
samples prepared from the minus 5/8” screened HPGR crusher product. Hence, it is reasonable to conclude 
that the uncrushed material in the HPGR is harder than the crushed product. 

  The  waste  material  had  a  BWi  higher  than  the  composite  sample  prepared  from  the  minus  5/8”  HPGR 

crusher product, as well as the XRT ore sorting products that are returned to the HPGR crushers. 

  The BWi for the products ranged from 23.10 to 24.28. A BWi of 24.50 was selected for the design of the 

primary ball mill circuit. 

The results of this test work support two main conclusions: (1) that the hardness of ore at the Batman deposit is relatively 
constant; and (2) that ore hardness at the Batman deposit does not change at depth. 

This test work validates the Company’s prior test work and supports Vista’s revised comminution circuit design, which 
is designed to crush and grind material with an average BWi of 26.2 kWh/t, a 5% factor of safety above the average BWi 
and closer to the 75th percentile of BWi test results. 

HPGR Crusher Selection 

The proposed Base Case comminution circuit incorporates the use of a gyratory crusher and two cone crushers for the 
primary  and  secondary  stages,  respectively,  and  contemplates  the  use  of  two  HPGR  crushers  as  the  third-stage  of  the 
crushing circuit.  

The  test  work  also  assessed  the  difference  in  power  requirements  between  a  primary/SAG/ball  mill  circuit,  a 
conventional 3-stage crush/ball mill circuit, and a 3-stage HPGR crush/ball mill circuit (with 3rd stage HPGR crushing 
and 2-stage grinding) to generate a P80 passing 40 μm product.  

This test work also confirms our prior test work and supports our comminution circuit design. The use of HPGR crushers 
is  anticipated  to  (a)  produce  a  product  that  can  be  ground  more  efficiently  (lower  BWi);  and  (b)  reduce  energy 
requirements when compared to a SAG mill design. 

Ore Sorting 

The bulk ore sorting tests comprised four, five-tonne composites prepared from 3.75" drill core. Three of the composites 
contained  predominately  sulfide  mineralization  and  one  composite  contained  mixed  oxide/sulfide  material  that  is 
encountered on the periphery of the deposit. The drill core was HPGR crushed and screened at plus 5/8” at the facilities 
of  Thyssen  Krupp  Industries  near  Dusseldorf,  Germany.  The  plus  5/8”  material  was  sent  to  the  test  facility  of  Tomra 
Sorting  Solutions  near  Hamburg,  Germany  where  this  material  was  initially  sorted  using  XRT  sorting.  A  total  of  12 
sorting tests were completed. The XRT rejects were then subjected to laser sorting to produce a final reject. All material 
(minus 5/8” HPGR crushed, XRT product, laser product and sorting reject) was sent to the metallurgical laboratory of 
Resource  Development  Inc.  in  Wheat  Ridge,  Colorado  for  subsequent  sample  preparation,  assaying  and  additional 
metallurgical testing. 

On a material  mass basis, the combined XRT and laser sorting tests confirmed the Company’s expectation that it can 
reject approximately 10% of the run-of-mine feed as waste (test results range from 6.8% to 11.0%). The average grade 
of the rejected material is estimated to be 0.12 g Au/t (results range from 0.06 g Au/t to 0.23 g Au/t) compared to the 
mine  cut-off  grade  of  0.4  g  Au/t,  resulting  in  a  gold  loss  from  the  rejected  waste  of  approximately  1.3%.  The 

41 

 
 
 
 
 
 
 
 
 
improvement in mill feed grade is expected to be approximately 8%, resulting in run-of-mine average mill feed grade of 
0.91 g Au/t compared to the life-of-mine Batman Pit mineral reserve grade of 0.84 g Au/t. 

Gold Recoveries 

We continued evaluating gold recoveries using two-stage grinding and a finer product size. This test work has confirmed 
that the introduction of ore sorting to reduce the leach tonnage by approximately 10% and finer grinding to P80 of 40 µm 
yields an increase in recovery to ~91.9% net of solution losses.  

A  total  of  71  additional  leach  tests  were  completed  using  the  above  mentioned  two-staged  grinding  to  confirm  our 
resulting leach recoveries of 91.9%, net of solution losses. This test work has also confirmed a cyanide consumption rate 
of 0.88 kg per tonne.  

Our recovery plant design utilizing a conventional, industry-proven, CIP circuit remains unchanged.  

Existing Heap Leach Pad 

In addition to analysis of freshly-mined material from the Batman deposit, Vista has analyzed the potential to process 
nearly 13.4 million tonnes of material from the existing heap leach pad at Mt Todd. The original Mt Todd started as a 
heap  leach  operation  with  historic  records  indicating  that  the  average  grade  of  material  placed  on  the  pad  was  0.96  g 
Au/t. Although the material was partially leached in the mid-1990s, Vista has drilled 24 air-rotary holes into the heap 
leach pad and assayed 361 samples, and Tetra Tech created a 3D resource model that has an average grade of 0.54 g 
Au/t. 

Initial evaluation efforts focused on re-starting the heap leach pad. Bottle roll and column tests were completed, both of 
which  supported  the  leachability  of  the  material  with  gold  recovery  rates  around  35%.  However,  poor  in  situ 
permeability rates caused Vista to ultimately abandon plans to re-start the heap. 

A  total  of 16  tests  were  completed  on  composites  taken  from  11  of  the heap  leach  pad  drill  holes. The  samples  were 
ground to the size of P80 of 40 μm and pre-treated with lime and 100 g/t of lead nitrate to suppress copper leaching. The 
material was then leached for 24 hours. These results ranged between 71 and 91% with the average being 82.2%for this 
material when processed through the CIP plant. 

The 2019 PFS assumes that the existing heap leach pad will be left in place and processed through the mill at the end of 
mine  life.  This  ultimately  is  expected  to  reduce  the  scope  of  reclamation  of  the  heap  leach  pad  to  the  pad  liner  and 
regrading only. 

Infrastructure 

Because Mt Todd was an operating mine, infrastructure exists that reduces initial capital expenditure and significantly 
reduces capital risk related to infrastructure construction, which has been a major source of capital cost overruns in the 
mining industry over the last decade. Existing mining infrastructure items include: 

 

 

 

 
 
 

an  existing  tailings  storage  facility  that  is  expected  to  contain  approximately  87  million  tonnes  of  material 
processed; 
an  existing  fresh  water  storage  reservoir  that  will  receive  a  two-meter  dam  raise  and will  harvest  stormwater 
sufficient to provide process water for year-round operations for a 50,000 tpd operation; 
a  natural  gas  pipeline  at  site  that  can  supply  sufficient  natural  gas  to  meet  the  project’s  energy  requirements 
which,  coupled  with  the planned power generating plant,  would  save  considerably  on  Project operating  costs 
compared to grid-supplied power; 
a paved road to site; 
current electrical connection to the NT electric grid; and 
reduced earthworks costs due to the process plant location being the same as the previous process plant, which 
has already been cleared and graded. 

42 

 
 
 
 
 
 
 
 
 
 
 
Other benefits of Mt Todd’s NT location include: 

 
 
 

the Stuart highway – the main North / South highway in the NT is less than 15 kilometers from the Project site; 
rail line parallel to the Stuart highway; and 
the  regional  center of Katherine  (population  approximately  12,000)  less  than 60 kilometers  from  site  and  the 
NT capital of Darwin less than 300 kilometers from the Project site, which has port access. 

The area has both historic and current mining activity and therefore a portion of the skilled workforce will be sourced 
locally. In addition, Katherine offers the necessary support functions that are found in a medium-sized city with regard to 
supplies, accommodations, communications, etc.  

Planned infrastructure for the site includes the following: 

  Ammonium Nitrate and Fuel Oil (ANFO) Facility; 

  Mine  Support  Facilities  (Heavy  Vehicle  (HV)  Workshop,  Lube  Farm,  Washdown  and  Tire  Change, 

Warehouse, Fuel Farm, Mining Offices, Core Storage Facility); 

  Heap Leach Facility; 

  Small Accommodation Camp for occasional contractor use; 

  Water Treatment Plant (WTP); 

  Power Supply; 

  Pit Dewatering; 

  Mine Services; 

  Communications; 

  Gatehouse; and 

  Expanded existing and additional TSF.  

Permitting 

During September 2014, the EIS was approved. In its Assessment Report, the NTEPA advised that it had assessed the 
environmental impacts of Vista’s development plans for Mt Todd and concluded that it can proceed, subject to a number 
of  recommendations  which  are  outlined  in  the  Assessment  Report.  The  NTEPA  Assessment  Report  includes  28 
recommendations which are to be addressed as part of the MMP.  

The approval of the EIS resulted in the requirement to obtain an authorization of a controlled activity as required under 
the  EPBC  as  it  relates  to  the  Gouldian  Finch.  The  EPBC  authorization  was  submitted  for  approval  to  the  Australian 
Commonwealth  Department  of  Environment  and  Energy  during  December  2015  and  the  authorization  was  granted  in 
January 2018.  

In November 2018, we applied for the MMP approval, which is the operating permit that sets out how mine operating 
strategy will be implemented throughout the mine life in compliance with the EIS and EPBC requirements. The MMP is 
currently under review by the DPIR. 

Environmental, Social and Community Factors 

A  number  of  environmental  studies  have  been  conducted  at  Mt  Todd  in  support  of  the  EIS  and  as  required  for 
environmental  and  operational  permits.  Studies  conducted  have  investigated  soils,  climate  and  meteorology,  geology, 
geochemistry,  biological  resources,  cultural  and  anthropological  sites,  socio-economics,  hydrogeology,  and  water 
quality. 

43 

 
 
 
 
 
 
 
 
 
 
 
The EIS for the project was submitted in June 2013. The document was prepared by independent consultants GHD Pty 
Ltd to identify potential environmental, social, transport, cultural and economic impacts associated with reopening and 
operating  the  mine.  NTEPA  provided  its  final  assessment  of  the  project  in  June  2014.  Final  approval  was  given  in 
September 2014. 

In January 2018, the “authorization of a controlled activity” was received for the project as required under the EBPC as 
it relates to the Gouldian Finch, and as such has received approval from the Australian Commonwealth Department of 
Environment and Energy. 

The  Jawoyn  people  have  been  consulted  with  and  involved  in  the  planning  of  the  project.  Areas  of  aboriginal 
significance have been designated, and the mine plan has avoided development in these restricted works areas. 

Water Treatment 

We have an approved WDL from the NT Government that authorizes the release of treated water from the Mt Todd site 
during the wet season in accordance with higher environmental protection standards. We operate in compliance with the 
standards.  The  existing  Batman  pit  has  the  capacity  to  contain  approximately  11.5  gigaliters  of  water.  At  the  end  of 
December 2019, the pit only contains 3.3 gigaliters of water due to previous dewatering operations. Under normal wet 
season discharge conditions, we are able to discharge approximately 2.5 gigaliters of water. Accordingly, we expect that 
dewatering of the pit will not present any major issues when resuming operations in the Batman pit. 

2019 Program Results 

In  January  2019,  we  announced  the  results  of  ore  sorting  tests  on  high-grade  samples.    These  tests  demonstrated  the 
efficiency  of  using  ore  sorting  across  a  wider  range  of  feed  grades.    Specifically,  the  results  demonstrated  a  natural 
concentration of gold in the fine fraction of the HPGR crusher product and lower gold losses from sorting high grade ore 
compared to sorting average or low grade ore. 

Subsequent metallurgical testing was completed to evaluate the optimal grind size.  Testing was completed to evaluate 
the efficiency of, and determine operating parameters for the IsaMill and VXP mill across a range of final grind sizes.  
Grinding  test  products  were  leached  to  provide  additional  data  about  the  relationship  between  grind  size  and  gold 
recovery.  The test program demonstrated that in our proposed application, the VXP mills could be expected to consume 
less power.  These results formed the basis for updated designs in the process plant and improved gold recoveries. 

In September 2019, we announced the results of an updated preliminary feasibility study.  This study incorporated the 
metallurgical test results and process area design changes, a gold price of US$1,350 per ounce, and a foreign exchange 
rate of US$0.70 per AUD.   

2020 Plans 

Our 2020 plans  will  leverage  the 2019  PFS  to further  advance  the  Project  and  demonstrate  that  Mt  Todd  is  poised  to 
become a major Australian gold producer. Among our priorities is to secure a development partner for Mt Todd. We also 
intend to continue de-risking and enhancing the value of Mt Todd in a cost-effective manner. This includes working with 
the  DPIR  to  gain  approval  of  the  MMP,  continuing  productive  engagement  with  the  JAAC  and  maintaining  our 
environmental  stewardship  programs.  We  expect  to  incur  approximately  $2,800  during  2020  for  these  activities  and 
other fixed costs associated with Mt Todd. Other discretionary programs consistent with these 2020 plans may also be 
undertaken, but no budgeted amounts have been determined at this time.  

Mt Todd is without known mineral reserves under SEC Industry Guide 7 and the project remains exploratory in nature. 

Guadalupe de los Reyes Gold/Silver Project, Sinaloa, Mexico 

During October 2017, we entered into an agreement (the “Option Agreement”) to option our interest in the Guadalupe de 
los  Reyes  gold  and  silver  project  in  Sinaloa,  Mexico  (“Los  Reyes”)  to  Minera  Alamos  Inc.  and  its  subsidiary  Minera 

44 

 
 
 
 
 
 
 
 
 
 
 
 
 
Alamos  de  Sonora  S.A. de C.V.  (“Minera  Alamos”).  In June  2019,  the  Option  Agreement  was  assigned  from  Minera 
Alamos  to  ePower  Metals  Inc.  by way of  an  assignment agreement  (the  “Assignment Agreement”), with our  consent. 
ePower  Metals  Inc.  subsequently  changed  its  name  to  Prime  Mining  Corporation  (“Prime  Mining”).  The  Assignment 
Agreement provides that in certain circumstances, the rights under the Option Agreement will revert from Prime Mining 
to Minera Alamos. 

Pursuant  to  the  terms  of  the Option Agreement  and  the Assignment  Agreement,  we granted  Minera  Alamos  or  Prime 
Mining, as applicable, (the “Optionholder”) an exclusive right and option right to earn a 100% interest in the Los Reyes 
project by: 

  making  payments  totaling  $6,000,  comprised  of  a  payment  of  $1,500  made  at  the  execution  of  the  Option 
Agreement (the “Option Grant Date”); two successive payments of $1,500 each to be made at the one-year and 
two-year anniversaries of the Option Grant Date; and a final $1,500 payment to be made before the four-year 
anniversary of the Option Grant Date; 

  maintaining the concessions comprising the Los Reyes project in good standing; 
 

fulfilling all obligations to the Ejido La Tasajera (the “Ejido”) as set out in the temporary occupation contract 
between us and the Ejido; 
granting  us  a  capped  net  smelter  return  royalty  (“NSR”)  on  production  from  open  pit  mining  (the  “Open  Pit 
NSR”) at rates that range from 1% (at gold prices of $1,400/oz or less) to a maximum of 2% (at gold prices 
above $1,600/oz) up to an aggregate of $2,000 in royalty payments; 
granting us a perpetual NSR on production from underground mining (the “Underground NSR”) at rates that 
range from 1% (at gold prices of $1,400/oz or less) to a maximum of 2% (at gold prices above $1,600/oz); and 
granting us the right to assume a 49% non-carried interest in an underground project if the Optionholder decides 
to develop an underground mine at the Los Reyes project (the “Back-in Right”). 

 

 

 

The Option Agreement provides that all cash payments are non-refundable and optional to the Optionholder, and in the 
event the Optionholder fails to pay any of the required amounts as set out in the Option Agreement, or fails to comply 
with  its  other obligations,  the  Option  Agreement  will  terminate  and  the  Optionholder will  have  no  interest  in  the Los 
Reyes project. Provided it is not in breach of the Option Agreement, the Optionholder may, at its discretion, accelerate 
the above payment schedule.  

Subject to the Optionholder timely making all the option payments, and fulfilling its other obligations with respect to the 
Option Agreement, we will transfer 100% of the shares of the Company’s 100% owned subsidiary Minera Gold Stake 
S.A. de C.V., the entity which owns the Los Reyes project, to the Optionholder and the Open-Pit NSR and Underground 
NSR will be granted to us. 

If the Optionholder discovers and decides to develop an underground mine at the Los Reyes project and we exercise the 
Back-in  Right,  we  and  the  Optionholder  have  agreed  to  form  a  joint  venture  to  develop  and  operate  the  underground 
mine. If the joint venture is formed, the Underground NSR will terminate. 

In October 2018, the Company agreed to extend the due date for the second $1,500 option payment under the Los Reyes 
Option  Agreement  by  six  months  to  April  23,  2019,  at  which  time  the  payment  was  made.  As  consideration  for  the 
deferral, the Company received an additional $150 in cash, $50 paid on October 24, 2018 and $100 paid on January 23, 
2019. In addition, the Optionholder paid interest of $67 at a rate of 1.5% per month on the unpaid balance of the $1,500 
payment beginning January 24, 2019. The third $1,500 option payment was received in October 2019. 

Guadalupe de los Reyes is without known mineral reserves under SEC Industry Guide 7 or NI 43-101 and the Company 
does not consider it a material mineral property at the time of this report. 

ITEM 3. LEGAL PROCEEDINGS. 

We are not aware of any material pending litigation or of any proceedings known to be contemplated by governmental 
authorities that are, or would be, likely to have a material adverse effect upon us or our operations, taken as a whole. 
There are no known material proceedings pursuant to which any of our directors, officers or affiliates or any owner of 

45 

 
 
 
 
 
 
 
 
record or beneficial owner of more than 5% of our securities or any associate of any such director, officer or security 
holder is a party adverse to us or has a material interest adverse to us.  

ITEM 4. MINE SAFETY DISCLOSURES. 

We consider health, safety and environmental stewardship to be a core value of the Company. 

Pursuant to Section 1503(a) of the United States Dodd-Frank Wall Street Reform and Consumer Protection Act of 2011 
(the “Dodd-Frank Act”), issuers that are operators, or that have a subsidiary that is an operator, of a coal or other mine in 
the  United  States  are  required  to  disclose  in  their  periodic  reports  filed  with  the  SEC  information  regarding  specified 
health  and  safety  violations,  orders  and  citations,  related  assessments  and  legal  actions,  and  mining-related  fatalities 
under the regulation of the Federal Mine Safety and Health Administration (“MSHA”) under the United States Federal 
Mine  Safety  and  Health  Act  of  1977  (the  “Mine  Act”).  During  the  fiscal  year  ended  December  31,  2019,  we  had  no 
properties in the United States and were not subject to regulation by the MSHA under the Mine Act and consequently no 
disclosure is required under Section 1503(a) of the Dodd-Frank Act.

Exchange Controls 

There are no governmental laws, decrees or regulations in Canada that restrict the export or import of capital, including 
foreign exchange controls, or that affect the remittance of dividends, interest or other payments to non-resident holders 
of  the  securities  of  Vista,  other  than  Canadian  withholding  tax.  See  “Certain  Canadian  Federal  Income  Tax 
Considerations for U.S. Residents” below.

Certain Canadian Federal Income Tax Considerations for U.S. Residents 

The  following  summarizes  certain  Canadian  federal  income  tax  consequences  generally  applicable  under  the  Income 
Tax Act  (Canada)  and  the  regulations  enacted  thereunder  (collectively,  the  “Canadian  Tax Act”)  and  the  Canada-
United States Income Tax Convention (1980) (the “Convention”) to the holding and disposition of Common Shares. 

Comment  is  restricted  to  holders  of  Common  Shares  each  of  whom,  at  all  material  times  for  the  purposes  of  the 
Canadian Tax Act and the Convention,  

(i) 
(ii) 
(iii) 
(iv) 

(v) 
(vi) 
(vii) 

is resident solely in the United States,  
is entitled to the benefits of the Convention, 
holds all Common Shares as capital property, 
holds no Common Shares that are “taxable Canadian property” (as defined in the Canadian Tax Act) of the 
holder,  
deals at arm’s length with and is not affiliated with Vista,  
does not and is not deemed to use or hold any Common Shares in a business carried on in Canada, and  
is not an insurer that carries on business in Canada and elsewhere  

(each such holder, a “U.S. Resident Holder”). 

Certain  U.S.-resident  entities  that  are  fiscally  transparent  for  United States  federal  income  tax  purposes  (including 
limited liability companies) are generally not themselves entitled to the benefits of the Convention. However, members 
of or holders of an interest in such entities that hold Common Shares may be entitled to the benefits of the Convention 
for income denied through such entities. Such members or holders should consult their own tax advisors in this regard. 

Generally, a holder’s Common Shares will be considered to be capital property of the holder provided that the holder is 
not a trader or dealer in securities, did not acquire, hold or dispose of the Common Shares in one or more transactions 
considered to be an adventure or concern in the nature of trade and does not hold the Common Shares as inventory in the 
course of carrying on a business.  

Generally, a holder’s Common Shares will not be “taxable Canadian property” of the holder at a particular time at which 
the Common Shares are listed on a “designated stock exchange” (which currently includes the TSX) unless both of the 
following conditions are met at any time during the 60 month period ending at the particular time: 

(i) 

the holder, persons with whom the holder does not deal at arm’s length, or any partnership in which the holder 
or persons with whom the holder did not deal at arm’s length holds a membership interest directly or indirectly 
through one or more partnerships, alone or in any combination, owned 25% or more of the issued shares of any 
class of the capital stock of Vista; and 

(ii)  more than 50% of the fair market value of the Common Shares was derived directly or indirectly from, or from 
any combination of, real or immovable property situated in Canada, “Canadian resource properties” (as defined 
in  the  Canadian  Tax  Act),  “timber  resource  properties”  (as  defined  in  the  Canadian  Tax  Act),  or  options  in 
respect of or interests in such properties. 

In certain other circumstances, a Common Share may be deemed to be “taxable Canadian property” for purposes of the 
Canadian Tax Act. 

This  summary  is  based  on  the  current  provisions  of  the  Canadian  Tax Act  and  the  Convention  in  effect  on  the  date 
hereof, all specific proposals to amend the Canadian Tax Act and Convention publicly announced by or on behalf of the 
Minister  of  Finance  (Canada)  on  or  before  the  date  hereof,  and  the  current  published  administrative  and  assessing 
policies of the CRA. It is assumed that all such amendments will be enacted as currently proposed, and that there will be 
no  other  material  change  to  any  applicable  law  or  administrative  or  assessing  practice,  although  no  assurance  can  be 
given in these respects. Except as otherwise expressly provided, this summary does not take into account any provincial, 
territorial or foreign tax considerations, which may differ materially from those set out herein. 

48 

 
 
 
 
 
 
 
 
 
 
 
This  summary  is  of  a  general  nature  only,  is  not  exhaustive  of  all  possible  Canadian  federal  income  tax 
considerations, and is not intended to be and should not be construed as legal or tax advice to any particular U.S. 
Resident Holder. U.S. Resident Holders are urged to consult their own tax advisers for advice with respect to their 
particular circumstances. The discussion below is qualified accordingly. 

A U.S. Resident Holder who disposes or is deemed to dispose of one or more Common Shares generally should 
not  thereby  incur  any  liability  for  Canadian  federal  income  tax  in  respect  of  any  capital  gain  arising  as  a 
consequence of the disposition. 

A U.S. Resident Holder to whom Vista pays or is deemed to pay a dividend on the holder’s Common Shares will 
be  subject  to  Canadian  withholding  tax,  and  Vista  will  be  required  to  withhold  the  tax  from  the  dividend  and 
remit it to the CRA for the holder’s account. The rate of withholding tax under the Canadian Tax Act is 25% of 
the gross amount of the dividend (subject to reduction under the provisions of an applicable tax treaty). Under 
the Convention, a U.S. Resident Holder who beneficially owns the dividend will generally be subject to Canadian 
withholding tax at the rate of 15 % (or 5%, if the U.S. Resident Holder who beneficially owns the dividend is a 
company that is not fiscally transparent and which owns at least 10% of the voting stock of Vista) of the gross 
amount of the dividend. 

Certain United States Federal Income Tax Considerations for U.S. Residents 

There may be material tax consequences to U.S. Residents in relation to an acquisition or disposition of Common Shares 
or other securities of the Company. U.S. Residents should consult their own legal, accounting and tax advisors regarding 
such tax consequences under United States, state, local or foreign tax law regarding the acquisition or disposition of our 
Common Shares or other securities, in particular, the tax consequences of the Company likely being a PFIC within the 
meaning of Section 1297 of the United States Internal Revenue Code. See the section “Item 1A. – Risk Factors – The 
Company is likely a PFIC, which will likely have adverse U.S. federal income tax consequences for U.S. shareholders” 
above. 

Unregistered Sales of Equity Securities 

None. 

Repurchase of Securities 

During 2019, neither Vista nor any affiliate of Vista repurchased Common Shares of Vista registered under Section 12 of 
the Exchange Act.

ITEM 7.  MANAGEMENT’S  DISCUSSION  AND  ANALYSIS  OF  FINANCIAL  CONDITION  AND  RESULTS 
OF OPERATIONS. 

The following discussion and analysis should be read in conjunction with our consolidated financial statements for the 
two years ended December 31, 2019 and 2018, and the related notes thereto, which have been prepared in accordance 
with  generally  accepted  accounting  principles  in  the  United  States  (“U.S.  GAAP”).  This  discussion  and  analysis 
contains  forward-looking  statements  that  involve  risks,  uncertainties  and  assumptions.  Our  actual  results  may  differ 
materially  from  those  anticipated  in  these  forward-looking  statements  as  a  result  of  many  factors,  including,  but  not 
limited to, those set forth under the section heading “Item 1A. Risk Factors” above and elsewhere in this annual report 
on Form 10-K. See section heading “Note Regarding Forward-Looking Statements” above. 

All  dollar  amounts  stated  herein  are  in  U.S. dollars  in  thousands,  unless  specified  otherwise,  except  per  share 
amounts. References to C$ refer to Canadian currency, AUD or A$ to Australian currency, and USD or $ to United 
States currency. 

Overview 

Vista  Gold  Corp.  and  its  subsidiaries  (collectively,  “Vista,”  the  “Company,”  “we,”  “our,”  or  “us”)  operate  in  the  gold 
mining  industry.  We  are  focused  on  the  evaluation,  acquisition,  exploration  and  advancement  of  gold  exploration  and 
potential development projects, which may lead to gold production or value adding strategic transactions such as earn-in 
right  agreements,  option  agreements,  leases  to  third  parties, joint  venture  arrangements  with  other  mining  companies,  or 
outright  sales  of  assets  for  cash  and/or  other  consideration.  We  look  for  opportunities  to  improve  the  value  of  our  gold 
projects through exploration drilling and/or technical studies focused on optimizing previous engineering work. We do not 
currently generate cash flows from mining operations. 

The  Company’s  flagship  asset  is  its  100%  owned  Mt  Todd  gold  project  (“Mt  Todd”  or  the  “Project”)  in  the  Northern 
Territory (“NT”) Australia. Mt Todd is the largest undeveloped gold project in Australia. In January 2018, the Company 
received  authorization  for  the  last  major  environmental  permit.  Vista  has  completed  additional  metallurgical  testing, 
including  ongoing  fine  grinding  evaluations,  which  demonstrate  further  improvements  in  gold  recovery.  In  September 
2019, the Company announced the results of an updated preliminary feasibility study. With these important milestones and 
subsequent project improvements complete, Vista is in a better position to identify and pursue a development partner that 
may provide the best opportunity for shareholders to realize fair value for Mt Todd. This also positions us to continue de-
risking and enhancing the value of Mt Todd in a cost-effective manner. We also hold 6.9 million shares of the outstanding 
common  shares  in  the  capital  of  Midas  Gold  Corp.  (“Midas  Gold  Shares”),  a  non-core  project  in  Mexico  and  royalty 
interests in the United States and Indonesia. 

Results from Operations 

Summary 

Consolidated net loss for the year ended December 31, 2019 was $9,386, or $0.09 per common share in the capital of 
Vista (each, a “Common Share”). Consolidated net loss and comprehensive loss for the year ended December 31, 2018 
was  $8,714  or  $0.09  per  Common  Share.  The  principal  components  of  our  2019  net  loss  and  these  year-over-year 
changes are discussed below. 

The Company had $7,756 of working capital and no debt as of December 31, 2019. 

Exploration, property evaluation and holding costs 

Exploration, property evaluation and holding costs, including fixed costs, discretionary programs, and non-cash stock-
based compensation, were $4,093 and $4,803 during the years ended December 31, 2019 and 2018, respectively. These 
costs are predominantly associated with Mt Todd and are comprised of fixed costs and discretionary costs.  

50 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
For the years ended December 31, 2019 and 2018 our fixed costs totaled $3,028 and $3,603, respectively. These costs 
include expenditures necessary to ensure that we preserve our property rights and meet all of our safety, regulatory and 
environmental responsibilities. The principal components of this decrease include a favorable AUD:USD exchange rate, 
which reduced costs in USD terms by about $300, non-discretionary exploration activities reduced by $170 in 2019, and 
water management costs which were $110 lower in 2019. 

Mt  Todd  2019  discretionary  programs  totaled  approximately  $1,065,  principally  for  additional  ore  sorting  testing  and 
update  of  the  Mt  Todd  preliminary  feasibility  study  which  was  completed  in  the  third  quarter  of  2019.  The  2018 
discretionary programs totaled approximately $1,200. The 2018 discretionary programs included large-scale ore sorting 
tests with subsequent metallurgical and grinding studies, and exploration drilling at Mt Todd.  

Included  in  the  2019  and  2018  exploration,  property  evaluation  and  holding  costs  were  non-cash  stock-based 
compensation of $172 and $249, respectively.  

Corporate administration  

Corporate  administration  costs  were  $3,940  and  $4,072  during  the  years  ended  December  31,  2019  and  2018, 
respectively.  Included  in  the  2019  and  2018  corporate  administration  costs  is  non-cash  stock-based  compensation  of 
$593 and $733 respectively. Other corporate administration costs were generally consistent during 2019 and 2018. 

Depreciation 

Depreciation costs were $52 and $983 during the years ended December 31, 2019 and 2018, respectively. Depreciation 
in  2018  includes  $695  to  adjust  the  net  book  value  of  plant  and  equipment  to  account  for  the  cumulative  effect  of 
immaterial calculation differences in prior years. 

Impairment of Used Mill Equipment 

In 2018, the Company evaluated the value of the mill equipment for recoverability. Based on an independent valuation 
by a qualified third party, and allowing for selling commissions and costs, the Company recorded a Level 3 impairment 
charge of $1,000 for the year ended December 31, 2018. Another valuation was conducted as of December 31, 2019, and 
no further impairment charge was required. 

Non-operating income and expenses   

Gain/(loss) on Other Investments 

Gain/(loss)  on  other  investments  was  $(1,643)  and  $1,716  for  the  years  ended  December  31,  2019  and  2018, 
respectively.  These  amounts  are  the  result  of  changes  in  fair  value  of  our  marketable  securities,  mainly  Midas  Gold 
Shares.  The  Company  sold  approximately  900,000  shares  of  Midas  Gold  and  received  net  proceeds  of  $413  with  a 
realized loss of $2 during the year ended December 31, 2019. There were no Midas Gold Share sales during the year 
ended December 31, 2018.  

Financial Position, Liquidity and Capital Resources 

Operating Activities 

Net  cash  used  in  operating  activities  was  $7,053  and  $8,567  for  the  years  ended  December  31,  2019  and  2018, 
respectively.  This  decline  of  $1,514  resulted  from  cash  of  $1,186  used  during  2018  to  reduce  accounts  payable  and 
accrued liabilities that resulted from relatively high discretionary program activity, including the 2018 PFS; $710 lower 
cash  expenditures  for  exploration  during  2019  compared  to  2018;  and  other  net  increases  in  cash  used  for  operating 
activities during 2019 of $382. 

51 

  
   
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Investing Activities 

Cash provided by investing activities of $7,377 for the year ended December 31, 2019 resulted primarily from $3,737 
received  for  net  redemptions  of  short-term  investments  comprised  of  U.S.  Government  Treasury  bills  and  notes  and 
receipt of $3,167 under the Guadalupe de los Reyes option agreement.  

Cash provided by investing activities of $8,304 for the year ended December 31, 2018 resulted primarily from $8,147 
received for net redemption of short-term investments comprised of U.S. Government Treasury bills and notes. 

Financing Activities 

Net cash of $13 for the year ended December 31, 2019 was provided by $89 received from exercised stock options less 
$76 for payment of certain employee withholding tax obligations in lieu of the issuance of common shares. 

Net cash of $97 for the year ended December 31, 2018 was provided by $86 received from exercised stock options less 
$122 utilized for the payment of certain employee withholding tax obligations in lieu of the issuance of common shares 
and $61 used to buy back stock options. 

Liquidity and Capital Resources 

Our cash and short-term investments as of December 31, 2019 decreased to $4,668 from $8,068 at December 31, 2018 
due mainly to operating activities as discussed above, partially offset by net proceeds from investing activities other than 
short  term  investments.  Our  net  working  capital  decreased  to  $7,756  as  at  December  31,  2019  from  $13,198  at 
December 31, 2018 due mainly to the decrease in cash and short-term investments to fund operating activities and the 
reduction  in  fair  value  of  our  Midas  Gold  Shares,  partially  offset  by  receipts  of  $3,167  under  the  Los  Reyes  Option 
Agreement.  

Although  working  capital  continued  to  decline  during  2019,  we  believe  our  existing  working  capital,  together  with 
potential future sources of non-dilutive financing, will be sufficient to fully fund for more than 12 months our currently 
planned corporate expenses and project holding costs, which we expect to be generally consistent with 2019 costs, and 
discretionary programs.  

Potential future sources of non-dilutive financing that management is seeking to convert to additional working capital 
include  monetization  of  royalty  interests  held  by  the  Company,  future  option  payments  under  the  Los  Reyes  Option 
Agreement and sales of non-core assets such as our used mill equipment. Vista has entered into agreements to monetize 
certain royalty interests during 2020 and 2021; however, payments to Vista are at the discretion of the counterparties. 
Should  any  of  the  counterparties  not  make  payments  when  due,  Vista  will  retain  the  respective  royalty  interests  and 
believes other monetization alternatives exist. The Los Reyes Option Agreement has one remaining option payment due, 
at  the  discretion  of  Prime  Mining,  in  October  2021.  The  used  mill  equipment  is  being  marketed  by  a  third-party  pre-
owned  mining  equipment  dealer.  The  Company  plans  to  continue  its  focus  on  monetizing  our  non-dilutive  potential 
sources of funding as existing working capital decreases.  

In  addition  to  existing  working  capital  and  other  potential  sources  of  non-dilutive  financing  highlighted  above,  the 
Company  has  an  at-the-market  offering  agreement  (the  “ATM  Agreement”)  with  H.  C.  Wainwright  &  Co.,  LLC 
(“Wainwright”) to provide additional balance sheet flexibility at a low cost. Under the ATM Agreement the Company 
may, but is not obligated to, issue and sell Common Shares through Wainwright as sales manager in an at-the-market 
offering  under  a  prospectus  supplement  to  a  base  shelf  prospectus  for  aggregate  sales  proceeds  of  up  to  $10,000  (the 
“ATM Program”). The ATM Agreement will remain in full force and effect until the earlier of August 31, 2020, or the 
date  that  the  ATM  Agreement  is  terminated  in  accordance  with  the  terms  therein.  Offers  or  sales  of  Common  Shares 
under the ATM Program will be made only in the United States, subject to an effective registration statement under the 
U.S. Securities Act of 1933, as amended, and no offers or sales of Common Shares under the ATM Agreement will be 
made in Canada. The Common Shares will be distributed at-the-market prices prevailing at the time of sale. As a result, 
prices of the Common Shares sold under the ATM Program may vary during the period of distribution. At December 31, 
2019 no offers or sales had been made under the ATM Program.

Vista’s viability beyond 12 months is dependent upon our ability to maintain our low expenditure profile, realize value 
from  non-dilutive  assets  and,  if  necessary,  issue  additional  equity  to  secure  sufficient  funding  to  advance  significant 
value-adding programs that will focus on generating future cash flows and positive equity returns to our shareholders. 
The  underlying  value  and  recoverability  of  the  amounts  shown  as  mineral  properties  and  plant  and  equipment  in  our 
Condensed Consolidated Balance Sheets are dependent on our ability to attract sufficient capital resources to execute our 
strategy and the ultimate success of our programs to enhance value, most importantly at Mt Todd. 

Fair Value Accounting 

The following table sets forth the Company’s assets measured at fair value within the fair value hierarchy. As required 
by accounting guidance, assets are classified in their entirety based on the lowest level of input that is significant to the 
fair value measurement.

Our other investments are classified as Level 1 of the fair value hierarchy as they are valued at unadjusted quoted market 
prices in an active market. Marketable securities are included in other current assets on the Consolidated Balance Sheets 
for each period presented.  

The mill equipment is classified as Level 3 of the fair value hierarchy as its value at 2018 was based on an independent 
third-party  valuation.  The  mill  equipment  is  included  in  plant  and  equipment  on  the  Consolidated  Balance  Sheets  for 
each period presented.  

There were no material transfers between levels nor were there any changes in valuation techniques in 2019. 

Off-Balance Sheet Arrangements 

We have no off-balance sheet arrangements required to be disclosed in this annual report on Form 10-K. 

Contractual Obligations 

We have no material contractual obligations as of December 31, 2019.

Critical Accounting Policies and Recent Accounting Pronouncements 

Critical accounting policies 

Principles of Consolidation 

The  Consolidated  Financial  Statements  include  the  accounts  of  Vista  and  more-than-50%-owned  subsidiaries  that  it 
controls.  All  significant  intercompany  balances  and  transactions  have  been  eliminated.  The  Consolidated  Financial 
Statements have been prepared in accordance with U.S. GAAP. 

Use of Estimates 

The  preparation  of  the  Company’s  Consolidated  Financial  Statements  requires  the  Company  to  make  estimates  and 
assumptions that affect the reported amounts of assets, liabilities, income and expenses during the reporting period. The 
more  significant  areas  requiring  the  use  of  management  estimates  and  assumptions  are:  the  fair  value  and  accounting 
treatment  of  financial  instruments;  useful  lives  of  assets  for  asset  depreciation  purposes;  valuation  allowances  for 
deferred  tax  assets;  the  fair  value  and  accounting  treatment  of  stock-based  compensation;  the  provision  for 
environmental  liabilities;  and  asset  impairments.  The  Company  bases  its  estimates  on  historical  experience  and  on 
various  other  assumptions  that  are  believed  to  be  reasonable  under  the  circumstances.  Actual  results  will  likely  differ 
from the amounts estimated in these financial statements.  

Cash and cash equivalents 

Cash and cash equivalents include cash on hand and government securities with original maturities of three months or 
less  when  purchased.  Because  of  the  short  maturity  of  these  investments,  the  carrying  amounts  approximate  their  fair 
values. 

Foreign Currency Transactions 

Our  functional  currency  is  the  U.S.  dollar.  Foreign  currency  transactions  denominated  in  currency  other  than  the 
functional  currency  are  recorded  at  the  approximate  rate  of  exchange  at  the  transaction  date  and  any  gains/(losses) 
resulting  therefrom  are  recorded  in  other  expense.  For  each  of  the  years  ended  December  31,  2019  and  2018,  we 
recorded insignificant net foreign currency gains/(losses).  

Short-term Investments 

Short-term investments consist of securities with original maturity dates greater than ninety days and less than one year. 
These securities are typically United States government treasury bills and/or notes. Short-term investments are recorded 
at amortized cost and are classified as debt securities held-to-maturity as the Company has the intention and ability to 
hold these instruments until their original maturity date at the time of purchase. 

Mineral Properties 

Mineral property acquisition costs, including directly related costs, are capitalized when incurred, and mineral property 
exploration costs are expensed as incurred. When we determine that a mineral property can be economically developed 
and  reserves  are  established  under  SEC  Industry  Guide  7,  costs  incurred  thereafter  to  develop  such  property  will  be 
capitalized. Capitalized costs will be depleted using the units-of-production method over the estimated life of the proven 
and probable reserves. If mineral properties are subsequently abandoned, any undepleted costs will be charged to loss in 
that period.  

The  recoverability  of  the  carrying  values  of  our  mineral  properties  is  dependent  upon  economic  reserves  being 
discovered  or  developed  on  the  properties,  permitting,  financing,  start-up,  and  commercial  production  from,  or  the 
sale/lease  of,  or  other  strategic  transactions  related  to  these  properties.  Development  and/or  start-up  of  any  of  these 
projects will depend on, among other things, management’s ability to raise sufficient capital for these purposes. Proceeds 

54 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
received  from  option or sale  agreements are  ascribed  to recovery  of  the carrying value  of  the  related  project  until  the 
carrying value reaches zero. Thereafter, any additional proceeds received are recognized as a contract liability (deferred 
option gain) until control has transferred to the buyer or the related contract terminates. 

We assess the carrying cost of our mineral properties for impairment whenever information or circumstances indicate the 
potential for impairment. This would include events and circumstances such as our inability to obtain all the necessary 
permits,  changes  in  the  legal  status  of our mineral  properties,  government  actions,  the  results  of  exploration  activities 
and  technical  evaluations  and  changes  in  economic  conditions,  including  the  price  of  gold  and  other  commodities  or 
input prices. Such evaluations compare estimated future net cash flows with our carrying costs and future obligations on 
an undiscounted basis. If  it  is  determined  that  the  estimated  future undiscounted  cash  flows  are  less  than  the  carrying 
value of the property, a write-down to the estimated fair value will then be reported in our Consolidated Statement of 
Income/(Loss)  and  Comprehensive  Income/(Loss)  for  the  period.  Where  estimates  of  future  net  cash  flows  are  not 
determinable  and  where  other  conditions  indicate  the  potential  for  impairment,  management  uses  available  market 
information  and/or  third-party  valuation  experts  to  assess  if  the  carrying  value  can  be  recovered  and  to  estimate  fair 
value.  

Impairment  

Carrying  values  of  long-lived  assets,  other  than  mineral  properties,  are  evaluated  for  impairment  at  such  time  that 
information becomes available indicating that the carrying value may not be recoverable. If it is determined that the fair 
value is less than the carrying value an impairment charge equal to the difference between the fair value and the carrying 
value will be recorded in our Consolidated Statements of Income/(Loss) and Comprehensive Income/(Loss). 

Stock-Based Compensation 

Under  our  stock  option,  long-term  incentive,  and  deferred  share  unit  plans,  the  Company  can  grant  stock  incentive 
options, restricted share units, and deferred share units to executives, employees, consultants and non-employee directors 
as applicable. Compensation expense for such grants is recorded in the Consolidated Statements of Income/(Loss) and 
Comprehensive  Income/(Loss)  as  a  component  of  exploration,  property  evaluation  and  holding  costs  and  corporate 
administration, with a corresponding increase to Common Shares in the Consolidated Balance Sheets. The fair values of 
options are calculated using the Black-Scholes option pricing model. The fair value of restricted and deferred share units 
is based on the closing price of our Common Shares on the grant date. The expense is based on the fair values of the 
grant on the grant date and is recognized over the vesting period specified for each grant. Forfeitures of unvested awards 
for all stock-based compensation result in expense reversal upon forfeiture.  

Financial Instruments 

Accounting Standards Codification Topic 820, Fair Value Measurements and Disclosures (“ASC 820”) of the Financial 
Accounting Standards Board (“FASB”) requires an entity to maximize the use of observable inputs and minimize the use 
of  unobservable  inputs  when  measuring  fair  value.  ASC  820  establishes  a  fair  value  hierarchy  based  on  the  level  of 
independent,  objective  evidence  surrounding  the  inputs  used  to  measure  fair  value.  A  financial  instrument’s 
categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value 
measurement. ASC 820 prioritizes the inputs into three levels that may be used to measure fair value: 

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

unrestricted assets or liabilities.  

  Level 2 – Observable inputs other than quoted prices included within Level 1 that are observable for the asset or 
liability, either directly or indirectly, including quoted prices for similar assets and liabilities in active markets; 
quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are 
observable or can be corroborated by observable market data by correlation or other means.  

  Level 3 – Prices or valuation techniques requiring inputs that are both significant to the fair value measurement 

and unobservable.  

55 

 
 
 
 
 
 
 
 
 
 
Our  financial  instruments  include  cash  and  cash  equivalents,  marketable  securities,  short-term  investments,  accounts 
payable  and  certain other  current  assets  and  liabilities.  Due  to  the  short-term  nature  of our  cash  and  cash  equivalents, 
short-term investments, accounts payable and certain other current assets and liabilities, we believe that their carrying 
amounts  approximate  fair  value.  Our  marketable  securities  are  classified  as  available-for-sale.  Accordingly,  these 
securities are carried at fair value, which is based upon quoted market prices in an active market and included in Level 1 
of the fair value hierarchy. Our other investments, comprised of Midas Gold Shares and other investments, are accounted 
for using the fair value option based on quoted market prices in an active market and are included in Level 1 of the fair 
value hierarchy. The mill equipment was valued using a third-party appraisal and is included in Level 3 of the fair value 
hierarchy.  

Recent accounting pronouncements   

Leases 

In February 2016, the FASB issued ASU No. 2016-02, Leases. This new standard established a right-of-use (“ROU”) 
model that requires a lessee to record an ROU asset and a lease liability on the balance sheet for all leases with terms 
longer  than  12  months.  Leases  are  classified  as  either finance or operating,  with  classification  affecting  the pattern  of 
expense recognition in the income statement. The Company adopted the standard on January 1, 2019 using the modified 
retrospective approach. We recognized additional liabilities of $186 on adoption, with corresponding ROU assets of the 
same amount, based on the present value of the remaining lease payments. Adoption of the standard did not affect lease 
classification or expense recognition. The discount rate used for discounting future payments was 13.6%. The Company 
does not include short term leases in its ROU asset and lease liability calculations. As of December 31, 2019, the ROU 
asset was $89 and the lease liability was $89, comprised of $81 included in accrued liabilities and other, and $8 in non-
current liabilities. The Company’s leases had remaining terms ranging from 0.3 to 2.3 years as of December 31, 2019. 

Non-U.S. GAAP Financial Measures 

In this report, we have provided information prepared or calculated according to U.S. GAAP, as well as provided some 
non-U.S.  GAAP  prospective  financial  performance  measures.  Because  the  non-U.S.  GAAP  performance  measures  do 
not  have  any  standardized  meaning  prescribed  by  U.S.  GAAP,  they  may  not  be  comparable  to  similar  measures 
presented by other companies. These measures should not be considered in isolation or as substitutes for measures of 
performance  prepared  in  accordance with U.S. GAAP.  There  are  limitations  associated with  the use  of  such  non-U.S. 
GAAP measures. Since these measures do not incorporate revenues, changes in working capital and non-operating cash 
costs, they are not necessarily indicative of potential operating profit or loss, or cash flow from operations as determined 
in accordance with U.S. GAAP.  

The non-U.S. GAAP measures Total Cash Costs, Cash Costs per ounce and All-in Sustaining Costs (“AISC”) per ounce 
are not, and are not intended to be, presentations in accordance with U.S. GAAP. As referenced in the 2019 PFS, these 
measures represent, respectively, our prospective cash costs and all-in sustaining costs related to our Project.  

We believe that these metrics help investors understand the economics of the Project. We present the Non-U.S. GAAP 
financial measures for our Project in the tables below. Actual U.S. GAAP results may vary from the amounts disclosed. 
Other companies may calculate these measures differently. 

Total Cash Costs and All-In Sustaining Costs 

Total Cash Costs, Cash Costs per ounce, and AISC per ounce are non-U.S. GAAP metrics developed by the World Gold 
Council to provide transparency into the costs associated with producing gold and provide a comparable standard. The 
Company reports Cash Costs and AISC per ounce because it believes that these metrics more completely reflect mining 
costs over the life of a mine. These metrics are widely used in the gold mining industry as a benchmark for performance.  

Total Cash Costs consist of operating costs net of power sales, refining costs, and non-government royalties, and exclude 
depreciation and amortization. The sum of these costs is divided by the corresponding gold ounces estimated to be sold 

56 

 
  
 
 
 
 
 
 
 
 
 
to  determine  a  Cash  Cost  per  ounce  amount.  The  Company’s  Total  Cash  Costs  exclude  the  allocation  of  corporate 
general and administrative costs. 

AISC consist of Total Cash Costs (as described above), plus sustaining capital costs. The sum of AISC is divided by the 
corresponding gold ounces estimated to be sold to determine AISC per ounce. 

Costs  excluded  from  Total  Cash  Costs  and  All-in  Sustaining  Costs  are  income  taxes,  government  royalties,  financing 
charges, costs related to business combinations, asset acquisitions other than sustaining capital, and asset dispositions. 

The following table reconciles the Mt Todd Total Cash Costs, Cash Costs per ounce and AISC per ounce amounts with 
the Project costs described in the 2019 PFS.

ITEM 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA. 

Management’s Report on Internal Control Over Financial Reporting  

The management of Vista Gold Corp. and its subsidiaries (collectively, “Vista,” the “Company,” “we,” “our,” or “us”) is 
responsible  for  establishing  and  maintaining  adequate  internal  control  over  financial  reporting.  Internal  control  over 
financial  reporting  is  a  process  designed  by,  or  under  the  supervision  of,  the  Company’s  principal  executive  and 
principal  financial  officers  and  effected  by  the  Company’s  board  of  directors  (the  “Board”),  management  and  other 
personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial 
statements  for  external  purposes  in  accordance  with  generally  accepted  accounting  principles.  Because  of  its  inherent 
limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any 
evaluation of effectiveness to future periods are subject to risk that controls may become inadequate because of changes 
in conditions, or that the degree of compliance with the policies or procedures may deteriorate.  

The  Company’s  management  assessed  the  effectiveness  of  the  Company’s  internal  control  over  financial  reporting  at 
December 31, 2019. In making this assessment, the Company’s management used the criteria set forth by the Committee 
of Sponsoring Organizations of the Treadway Commission Internal Control-Integrated Framework in 2013. Based upon 
its  assessment,  management  concluded  that,  at  December  31,  2019,  the  Company’s  internal  control  over  financial 
reporting was effective.  

The effectiveness of the Company’s assessment of internal control over financial reporting at December 31, 2019 has 
been audited by Plante & Moran, PLLC, an independent registered public accounting firm, as stated in their report titled 
Report of Independent Registered Public Accounting Firm which appears herein.

Report of Independent Registered Public Accounting Firm 

To the Stockholders and Board of Directors of Vista Gold Corp. 

Opinions on the Financial Statements and Internal Control over Financial Reporting 

We have audited the accompanying consolidated balance sheets of Vista Gold Corp. (the “Company”) as of December 
31, 2019 and 2018, the related consolidated statements of income/(loss) and comprehensive income/(loss), stockholders' 
equity,  and  cash  flows  for  each  of  the  years  in  the  two-year  period  ended  December  31,  2019,  and  the  related  notes 
(collectively  referred  to  as  the  “financial  statements”).  We  also  have  audited  the  Company's  internal  control  over 
financial reporting as of December 2019, based on criteria established in Internal Control-Integrated Framework (2013) 
issued by the Committee of Sponsoring Organizations of the Treadway Commission (the “COSO framework”). 

In our opinion, the financial statements referred to above present fairly, in all material respects, the financial position of 
the Company as of December 31, 2019 and 2018, and the results of its operations and its cash flows for each of the years 
in  the  two-year  period  ended  December  31,  2019,  in  conformity  with  accounting  principles  generally  accepted  in  the 
United  States  of  America.  Also,  in  our  opinion,  the  Company  maintained,  in  all  material  respects,  effective  internal 
control over financial reporting as of December 31, 2019, based on criteria established in the COSO framework. 

Basis for Opinion 

The Company's management is responsible for these financial statements, for maintaining effective internal control over 
financial reporting, and for its assessment of the effectiveness of internal control over financial reporting, included in the 
accompanying Management’s Report on Internal Control Over Financial Reporting. Our responsibility is to express an 
opinion  on  the  Company’s  financial  statements  and  an  opinion  on  the  Company's  internal  control  over  financial 
reporting  based  on  our  audits.  We  are  a  public  accounting  firm  registered  with  the  Public  Company  Accounting 
Oversight  Board  (United  States)  (“PCAOB”)  and  are  required  to  be  independent  with  respect  to  the  Company  in 
accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange 
Commission and the PCAOB. 

We  conducted  our  audits  in  accordance  with  the  standards  of  the  PCAOB.  Those  standards  require  that  we  plan  and 
perform  the  audits  to  obtain  reasonable  assurance  about  whether  the  financial  statements  are  free  of  material 
misstatement,  whether  due  to  error  or  fraud,  and  whether  effective  internal  control  over  financial  reporting  was 
maintained in all material respects. 

Our audits of the financial statements included performing procedures to assess the risks of material misstatement of the 
financial  statements,  whether  due  to  error  or  fraud,  and  performing  procedures  that  respond  to  those  risks.  Such 
procedures  included  examining,  on  a  test  basis,  evidence  regarding  the  amounts  and  disclosures  in  the  financial 
statements.  Our  audits  also  included  evaluating  the  accounting  principles  used  and  significant  estimates  made  by 
management, as well as evaluating the overall presentation of the financial statements. Our audit of internal control over 
financial  reporting  included  obtaining  an  understanding  of  internal  control  over  financial  reporting,  assessing  the  risk 
that  a  material  weakness  exists,  and  testing  and  evaluating  the  design  and  operating  effectiveness  of  internal  control 
based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the 
circumstances. We believe that our audits provide a reasonable basis for our opinions. 

Definition and Limitations of Internal Control over Financial Reporting 

A company's internal control over financial reporting 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 
generally accepted accounting principles. A company's internal control over financial reporting includes those policies 
and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the 
transactions  and  dispositions  of  the  assets  of  the  company;  (2)  provide  reasonable  assurance  that  transactions  are 
recorded  as  necessary  to  permit  preparation  of  financial  statements  in  accordance  with  generally  accepted  accounting 
principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of 
management  and  directors  of  the  company;  and  (3)  provide  reasonable  assurance  regarding  prevention  or  timely 

58 

 
 
detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the 
financial statements. 

Because  of  its  inherent  limitations,  internal  control  over  financial  reporting  may  not  prevent  or  detect  misstatements. 
Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become 
inadequate  because  of  changes  in  conditions,  or  that  the  degree  of  compliance  with  the  policies  or  procedures  may 
deteriorate.

VISTA GOLD CORP. 
NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS 
(Dollar amounts in U.S. dollars and in thousands, except share amounts and per ounce amounts) 

1. Nature of Operations 

Vista operates in the gold mining industry. We are focused on the evaluation, acquisition, exploration and advancement 
of  gold  exploration,  and  potential  development  projects,  that  may  lead  to  gold  production  or  value  adding  strategic 
transactions such as earn-in right agreements, option agreements, leases to third parties, joint venture arrangements with 
other  mining  companies,  or  outright  sales  of  assets  for  cash  and/or  other  consideration.  We  look  for  opportunities  to 
improve  the  value  of  our  gold  projects  through  exploration  drilling  and/or  technical  studies  focused  on  optimizing 
previous engineering work. We do not currently generate cash flows from mining operations. 

The Company’s flagship asset is its 100% owned Mt Todd gold project (“Mt Todd” or the “Project”) in the Northern 
Territory Australia. Mt Todd is the largest undeveloped gold project in Australia. We have invested substantial amounts 
to evaluate, engineer, permit and de-risk the Project. We believe these efforts have added to the underlying value of the 
Project and demonstrate strong development potential. In January 2018, the Company announced positive results of an 
updated preliminary feasibility study for Mt Todd (the “2018 PFS”). Later in 2018 and in 2019, we continued additional 
metallurgical  testing  that  demonstrated  improved  gold  recovery  compared  to  the  2018  PFS.  These  test  results,  other 
findings  and  the  outcome  of  an  independent  benchmarking  study  were  incorporated  into  an  updated  preliminary 
feasibility study, which was issued in October 2019 .  

As of December 31, 2019, the Company holds 6.9 million shares of Midas Gold Corp. (“Midas Gold Shares”), a non-
core project in Mexico subject to a third-party option agreement, royalty interests in the United States and Indonesia, and 
other miscellaneous holdings of third-party equity securities. 

All  dollar  amounts  stated  herein  are  in  U.S. dollars  in  thousands,  except  per  share  amounts  and  per warrant  amounts 
unless specified otherwise. References to C$ refer to Canadian currency, AUD or A$ to Australian currency, and USD or 
$ to United States currency. 

2. Significant Accounting Policies 

Principles of Consolidation 

The  Consolidated  Financial  Statements  include  the  accounts  of  Vista  and  more-than-50%-owned  subsidiaries  that  it 
controls.  All  significant  intercompany  balances  and  transactions  have  been  eliminated.  The  Consolidated  Financial 
Statements have been prepared in accordance with U.S. GAAP. 

Use of Estimates 

The  preparation  of  the  Company’s  Consolidated  Financial  Statements  requires  the  Company  to  make  estimates  and 
assumptions that affect the reported amounts of assets, liabilities, income and expenses during the reporting period. The 
more  significant  areas  requiring  the  use  of  management  estimates  and  assumptions  are:  the  fair  value  and  accounting 
treatment  of  financial  instruments;  useful  lives  of  assets  for  asset  depreciation  purposes;  valuation  allowances  for 
deferred  tax  assets;  the  fair  value  and  accounting  treatment  of  stock-based  compensation;  the  provision  for 
environmental  liabilities;  and  asset  impairments.  The  Company  bases  its  estimates  on  historical  experience  and  on 
various other assumptions  that  are believed  to be reasonable under  the circumstances.  Accordingly, actual  results will 
likely differ from the amounts estimated in these financial statements.  

Cash and cash equivalents 

Cash and cash equivalents include cash on hand and government securities with original maturities of three months or 
less  when  purchased.  Because  of  the  short  maturity  of  these  investments,  the  carrying  amounts  approximate  their  fair 
values. 

64 

 
 
 
 
 
 
 
 
 
 
 
 
 
Foreign Currency Transactions 

Our  functional  currency  is  the  U.S.  dollar.  Foreign  currency  transactions  denominated  in  currency  other  than  the 
functional  currency  are  recorded  at  the  approximate  rate  of  exchange  at  the  transaction  date  and  any  gains/(losses) 
resulting  therefrom  are  recorded  in  other  expense.  For  each  of  the  years  ended  December  31,  2019  and  2018,  we 
recorded insignificant net foreign currency gains/(losses).  

Short-term Investments 

Short-term investments consist of securities with original maturity dates greater than ninety days and less than one year. 
These securities are typically United States government treasury bills and/or notes. Short-term investments are recorded 
at amortized cost and are classified as debt securities held-to-maturity as the Company has the intention and ability to 
hold these instruments until their original maturity date at the time of purchase. 

Mineral Properties 

Mineral property acquisition costs, including directly related costs, are capitalized when incurred, and mineral property 
exploration costs are expensed as incurred. When we determine that a mineral property can be economically developed 
and  reserves  are  established  under  SEC  Industry  Guide  7,  costs  incurred  thereafter  to  develop  such  property  will  be 
capitalized. Capitalized costs will be depleted using the units-of-production method over the estimated life of the proven 
and probable reserves. If mineral properties are subsequently abandoned, any undepleted costs will be charged to loss in 
that period. 

The  recoverability  of  the  carrying  values  of  our  mineral  properties  is  dependent  upon  economic  reserves  being 
discovered  or  developed  on  the  properties,  permitting,  financing,  start-up,  and  commercial  production  from,  or  the 
sale/lease  of,  or  other  strategic  transactions  related  to  these  properties.  Development  and/or  start-up  of  any  of  these 
projects will depend on, among other things, management’s ability to raise sufficient capital for these purposes. Proceeds 
received  from  option or sale  agreements are  ascribed  to recovery  of  the carrying value  of  the  related  project  until  the 
carrying value reaches zero. Thereafter, any additional proceeds received are recognized as a contract liability (deferred 
option gain) until control has transferred to the buyer or the related contract terminates. 

We assess the carrying cost of our mineral properties for impairment whenever information or circumstances indicate the 
potential for impairment. This would include events and circumstances such as our inability to obtain all the necessary 
permits,  changes  in  the  legal  status  of our mineral  properties,  government  actions,  the  results  of  exploration  activities 
and  technical  evaluations  and  changes  in  economic  conditions,  including  the  price  of  gold  and  other  commodities  or 
input prices. Such evaluations compare estimated future net cash flows with our carrying costs and future obligations on 
an undiscounted basis. If  it  is  determined  that  the  estimated  future undiscounted  cash  flows  are  less  than  the  carrying 
value of the property, a write-down to the estimated fair value will then be reported in our Consolidated Statement of 
Income/(Loss)  and  Comprehensive  Income/(Loss)  for  the  period.  Where  estimates  of  future  net  cash  flows  are  not 
determinable  and  where  other  conditions  indicate  the  potential  for  impairment,  management  uses  available  market 
information  and/or  third-party  valuation  experts  to  assess  if  the  carrying  value  can  be  recovered  and  to  estimate  fair 
value.  

Impairment  

Carrying  values  of  long-lived  assets,  other  than  mineral  properties,  are  evaluated  for  impairment  at  such  time  that 
information becomes available indicating that the carrying value may not be recoverable. If it is determined that the fair 
value is less than the carrying value an impairment charge equal to the difference between the fair value and the carrying 
value will be recorded in our Consolidated Statements of Income/(Loss) and Comprehensive Income/(Loss). 

Stock-Based Compensation 

Under our stock option, long-term incentive, and deferred share unit plans, the Company can grant stock incentive 
options, restricted share units, and deferred share units to executives, employees, consultants and non-employee directors 

65 

 
 
 
 
 
 
 
 
 
 
 
as applicable. Compensation expense for such grants is recorded in the Consolidated Statements of Income/(Loss) and 
Comprehensive Income/(Loss) as a component of exploration, property evaluation and holding costs and corporate 
administration, with a corresponding increase to Common Shares in the Consolidated Balance Sheets. The fair values of 
options are calculated using the Black-Scholes option pricing model. The fair value of restricted and deferred share units 
is based on the closing price of our Common Shares on the grant date. The expense is based on the fair values of the 
grant on the grant date and is recognized over the vesting period specified for each grant. Forfeitures of unvested awards 
for all stock-based compensation result in expense reversal upon forfeiture. 

Financial Instruments 

Accounting Standards Codification Topic 820, Fair Value Measurements and Disclosures (“ASC 820”) of the Financial 
Accounting Standards Board (“FASB”) requires an entity to maximize the use of observable inputs and minimize the use 
of  unobservable  inputs  when  measuring  fair  value.  ASC  820  establishes  a  fair  value  hierarchy  based  on  the  level  of 
independent,  objective  evidence  surrounding  the  inputs  used  to  measure  fair  value.  A  financial  instrument’s 
categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value 
measurement. ASC 820 prioritizes the inputs into three levels that may be used to measure fair value: 

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

unrestricted assets or liabilities.  

  Level 2 – Observable inputs other than quoted prices included within Level 1 that are observable for the asset or 
liability, either directly or indirectly, including quoted prices for similar assets and liabilities in active markets; 
quoted prices for identical or similar assets and liabilities in markets that are not active; or other inputs that are 
observable or can be corroborated by observable market data by correlation or other means.  

  Level 3 – Prices or valuation techniques requiring inputs that are both significant to the fair value measurement 

and unobservable.  

Our  financial  instruments  include  cash  and  cash  equivalents,  marketable  securities,  short-term  investments,  accounts 
payable  and  certain other  current  assets  and  liabilities.  Due  to  the  short-term  nature  of our  cash  and  cash  equivalents, 
short-term investments, accounts payable and certain other current assets and liabilities, we believe that their carrying 
amounts  approximate  fair  value.  Our  marketable  securities  are  classified  as  available-for-sale.  Accordingly,  these 
securities are carried at fair value, which is based upon quoted market prices in an active market and included in Level 1 
of the fair value hierarchy. Our other investments, comprised of Midas Gold Shares and other investments, are accounted 
for using the fair value option based on quoted market prices in an active market and are included in Level 1 of the fair 
value hierarchy. The mill equipment was valued using a third-party appraisal and is included in Level 3 of the fair value 
hierarchy.  

Recent accounting pronouncements   

Leases 

In February 2016, the FASB issued ASU No. 2016-02, Leases. This new standard established a right-of-use (“ROU”) 
model that requires a lessee to record an ROU asset and a lease liability on the balance sheet for all leases with terms 
longer  than  12  months.  Leases  are  classified  as  either finance or operating,  with  classification  affecting  the pattern  of 
expense recognition in the income statement. The Company adopted the standard on January 1, 2019 using the modified 
retrospective approach. We recognized additional liabilities of $186 on adoption, with corresponding ROU assets of the 
same amount, based on the present value of the remaining lease payments. Adoption of the standard did not affect lease 
classification or expense recognition. The discount rate used for discounting future payments was 13.6%. The Company 
does not include short term leases in its ROU asset and lease liability calculations. As of December 31, 2019, the ROU 
asset was $89 and the lease liability was $89, comprised of $81 included in accrued liabilities and other, and $8 in non-
current liabilities. The Company’s leases had remaining terms ranging from 0.3 to 2.3 years as of December 31, 2019.

3. Other Investments 

Short-term investments 

As  of  December  31,  2019  and  2018,  the  amortized  cost  basis  of  our  short-term  investments  was  $3,260  and  $6,997, 
respectively. The amortized cost basis approximates fair value at December 31, 2019 and 2018. Short-term investments 
at  December  31,  2019  and  2018  are  comprised  of  U.S.  Government  treasury  bills  and/or  notes,  all  of  which  have 
maturity dates greater than 90 days but less than one year. 

Other investments 

Investments in marketable securities are recorded at fair value in the Consolidated Balance Sheets. Subsequent changes 
in  fair  value  are  recorded  in  the  Consolidated  Statements  of  Income/(Loss)  and  Comprehensive  Income/(Loss)  in  the 
period in which they occur. Most of our other investments are our investment in Midas Gold. We held 7,802,615 shares 
of  Midas  Gold  at  December  31,  2018.  During  the  year  ended  December  31,  2019,  the  Company  sold  920,500  Midas 
Gold Shares for net proceeds of $413 and a loss of $2  compared to the  most recent measurement  period. Cumulative 
realized loss since acquisition of these Midas shares was $1,975, of which $1,973 was recognized in previous periods as 
unrealized loss, net. We held 6,882,115 shares of Midas Gold at December 31, 2019. The Company also held 1,333,334 
shares of Nusantara Resources Limited (“Nusantara Resources”) as of December 31, 2019. Of the $1,643 unrealized loss 
in 2019, $230 related to the 920,500 Midas Gold shares sold in 2019 and $1,413 related to the remaining Midas Gold 
and Nusantara Resources shares held at December 31, 2019. 

The following table summarizes our investments in marketable securities as at December 31, 2019 and 2018.

During October 2017, we entered into an agreement (the “Option Agreement”) to option our interest in the Guadalupe de 
los  Reyes  gold  and  silver  project  in  Sinaloa,  Mexico  (“Los  Reyes”)  to  Minera  Alamos  Inc.  and  its  subsidiary  Minera 
Alamos  de  Sonora  S.A. de C.V.  (“Minera  Alamos”).  In June  2019,  the  Option  Agreement  was  assigned  from  Minera 
Alamos  to  ePower  Metals  Inc.  by way of  an  assignment agreement  (the  “Assignment Agreement”), with our  consent. 
ePower  Metals  Inc.  subsequently  changed  its  name  to  Prime  Mining  Corporation  (“Prime  Mining”).  The  Assignment 
Agreement provides that in certain circumstances, the rights under the Option Agreement will revert from Prime Mining 
to Minera Alamos. 

Pursuant  to  the  terms  of  the Option Agreement  and  the Assignment  Agreement,  we granted  Minera  Alamos  or  Prime 
Mining, as applicable, (the “Optionholder”) an exclusive right and option right to earn a 100% interest in the Los Reyes 
project by: 

  making  payments  totaling  $6,000,  comprised  of  a  payment  of  $1,500  made  at  the  execution  of  the  Option 
Agreement (the “Option Grant Date”); two successive payments of $1,500 each to be made at the one-year and

two-year anniversaries of the Option Grant Date; and a final $1,500 payment to be made before the four-year 
anniversary of the Option Grant Date; 

  maintaining the concessions comprising the Los Reyes project in good standing; 
 

fulfilling all obligations to the Ejido La Tasajera (the “Ejido”) as set out in the temporary occupation contract 
between us and the Ejido; 
granting  us  a  capped  net  smelter  return  royalty  (“NSR”)  on  production  from  open  pit  mining  (the  “Open  Pit 
NSR”) at rates that range from 1% (at gold prices of $1,400/oz or less) to a maximum of 2% (at gold prices 
above $1,600/oz) up to an aggregate of $2,000 in royalty payments; 
granting us a perpetual NSR on production from underground mining (the “Underground NSR”) at rates that 
range from 1% (at gold prices of $1,400/oz or less) to a maximum of 2% (at gold prices above $1,600/oz); and 
granting us the right to assume a 49% non-carried interest in an underground project if the Optionholder decides 
to develop an underground mine at the Los Reyes project (the “Back-in Right”). 

 

 

 

The Option Agreement provides that all cash payments are non-refundable and optional to the Optionholder, and in the 
event the Optionholder fails to pay any of the required amounts as set out in the Option Agreement, or fails to comply 
with  its  other obligations,  the  Option  Agreement  will  terminate  and  the  Optionholder will  have  no  interest  in  the Los 
Reyes project. Provided it is not in breach of the Option Agreement, the Optionholder may, at its discretion, accelerate 
the above payment schedule.  

Subject to the Optionholder timely making all the option payments, and fulfilling its other obligations with respect to the 
Option Agreement, we will transfer 100% of the shares of the Company’s 100% owned subsidiary Minera Gold Stake 
S.A. de C.V., the entity which owns the Los Reyes project, to the Optionholder and the Open-Pit NSR and Underground 
NSR will be granted to us. 

If the Optionholder discovers and decides to develop an underground mine at the Los Reyes project and we exercise the 
Back-in  Right,  we  and  the  Optionholder  have  agreed  to  form  a  joint  venture  to  develop  and  operate  the  underground 
mine. If the joint venture is formed, the Underground NSR will terminate. 

In October 2018, the Company agreed to extend the due date for the second $1,500 option payment under the Los Reyes 
Option  Agreement  by  six  months  to  April  23,  2019,  at  which  time  the  payment  was  made.  As  consideration  for  the 
deferral, the Company received an additional $150 in cash, $50 paid on October 24, 2018 and $100 paid on January 23, 
2019. In addition, Minera Alamos paid interest of $67 at a rate of 1.5% per month on the unpaid balance of the $1,500 
payment beginning January 24, 2019. The third $1,500 option payment was received in October 2019. 

The Company has determined that control of the Los Reyes project has not been transferred for accounting purposes. 
Therefore, the first option payment of $1,500 received in October 2017 and the $150 for extension of the second option 
payment  were  accounted  for  as  a  reduction  to  carrying  value.  Receipt  of  the  second  option  payment  of  $1,500  and 
interest of $67 during April 2019 reduced the carrying value to zero and resulted in recognition of $1,392 as a deferred 
option gain. The third Los Reyes project option payment of $1,500 was received from Prime Mining in October 2019 
which increased the deferred option gain to $2,892. The deferred option gain will be recognized upon the earlier of the 
Optionholder completion the final option payment of $1,500 and transfer of title of the Los Reyes project or cancellation 
of  the  agreement.  Potential  royalty  revenue  and  scheduled  future  option  payments  have  not  been  recognized  for 
accounting purposes. 

Awak Mas 

On November 1, 2019, we entered into an agreement with PT Masmindo Dwi Area, the entity that holds the Awak Mas 
project,  to  amend  the  Company’s  royalty  agreement  with  Awak  Mas.  PT  Masmindo  Dwi  Area  is  a  wholly  owned 
subsidiary of Nusantara Resources. As consideration for entering into the amendment, Nusantara Resources made a $100 
payment and issued 666,667 of its shares with a value of $136 to Vista on November 1, 2019. Including shares acquired 
through  a  previous  transaction, Vista  now holds  a  total of  1,333,334  shares  of Nusantara  Resources,  representing  less 
than  1%  of  the  issued  and  outstanding  shares.  The  amendment  modifies  the  original  royalty  agreement  to  allow  PT 
Masmindo Dwi Area or a nominated party to make a $2,400 payment to Vista by April 30, 2020, which will cancel a 1% 
NSR on the first 1,250,000 ounces produced at Awak Mas and a 1.25% NSR on the next 1,250,000 ounces produced. If 

68

We  continue  to  actively  market  the  used  mill  equipment,  however,  we  do  not  classify  it  as  ‘held  for  sale’  on  our 
Consolidated  Balance  Sheets  as  of  December  31,  2019  or  2018  as  we  do  not  have  reasonable  assurance  that  the  mill 
equipment  will  sell  within  12  months.  We  are  not  currently  depreciating  the  used  mill  equipment  as  we  continue  to 
market it and it is not in use. Based on an independent valuation report prepared by a qualified third party, and allowing 
for  selling  commissions  and  costs,  the  Company  recorded  a  Level  3  impairment  charge  of  $1,000  for  the  year  ended 
December 31, 2018. The carrying value of the used mill equipment is $5,500 as of December 31, 2019 and 2018. 

December 31, 2018 cost basis and accumulated depreciation totals were adjusted for fully depreciated assets which were 
no longer in use and had been removed from service. The Company recorded additional depreciation of $695 in 2018 to 
adjust  the  net  book  value  of  plant  and  equipment  to  account  for  the  cumulative  effect  of  immaterial  calculation 
differences in prior years. No such adjustments were made in 2019.

Under the Company’s stock option plan (the “Plan”), we may grant options to purchase Common Shares in the capital of 
the  Company  (“Common  Shares”)  to  our  directors,  officers,  employees  and  consultants.  The  maximum  number  of 
Common  Shares  that  may  be  reserved  for  issuance  under  the  Plan,  together  with  all  other  stock-based  compensation 
arrangements, which include RSUs currently outstanding under the Company’s long term equity incentive plan (“LTIP”) 
and  deferred  share  units  (“DSUs”)  issuable  pursuant  to  the  Company’s  deferred  share  unit  plan  (“DSU  Plan”),  is  a 
variable number equal to 10% of the issued and outstanding Common Shares on a non-diluted basis at any one time. Any

cash. Options, RSUs, DSUs, and phantom units are granted from time to time at the discretion of the Board of Directors 
of the Company (the “Board”), with vesting periods and other terms as determined by the Board.

The fair value of stock options granted during the years ended December 31, 2019 and 2018 to employees, directors and 
consultants was estimated at the grant date using the Black-Scholes option pricing model using the following weighted-
average assumptions:  

Expected volatility 
Risk-free interest rate 
Expected life (years) 
Dividend yield 
Forfeiture assumption 

2019 
 61.1 %  
 2.0 %  
 2.8  

0 %  
0 %  

2018 
 76.2 %   
 2.7 %   
 5.0  

0 %   
0 %   

Option  pricing  models  require  the  input  of  highly  subjective  assumptions,  including  the  expected  price  volatility. 
Expected  price  volatility  is  based  on  the  historical  volatility  of our  Common  Shares.  Changes  in  the  subjective  input 
assumptions can materially affect the fair value estimate. The expected term of the options granted represents the period 
of time that the options granted are expected to be outstanding using the simplified approach. The risk-free rate for the 
periods within the contractual term of the option is based on the U.S. Treasury yield curve in effect at the date of grant. 

Option Amendment 

In July 2018, the Company amended certain 2013 stock option agreements, expiring December 30, 2018 subject to the 
potential  for  a  temporary  extension  under  the  terms  of  the  Plan,  for  seven  executives  and  directors  (the  “Option 
Amendment”).  The  amendment  provided  each  grantee  the  opportunity  to  receive  a  cash  buyout  of  certain  vested, 
unexercised 2013 options in lieu of exercising the option to purchase shares. This cash buyout was based on the intrinsic 
value of each option at the time of the buyout as determined by the Company’s Compensation Committee prior to the 
buyout. As a result of this modification, the Company accounted for these options as awards classified as liabilities. The 
options  were  previously  accounted  for  as  awards  classified  as  equity.  The  Company  recognized  no  additional 
compensation  expense  in  the  year  ended  December  31,  2018.  In  December  2018,  all  options  under  the  Option 
Amendment were settled with cash buyouts totaling $61 and the related options were cancelled.

During the years ended December 31, 2019 and 2018, the Company withheld shares equivalent to the value of employee 
withholding  tax  obligations  which  resulted  from  RSUs  vesting  in  the  period.  Shares  withheld  are  considered 
cancelled/forfeited.  

Under the LTIP, a portion of the RSU awards vest on a fixed future date provided the recipient continues to be affiliated 
with  Vista  on  that  date.  Other  RSU  awards  vest  subject  to  certain  performance  and  market  criteria,  including  the 
accomplishment  of  certain  corporate  objectives  and  the  Company’s  share  price  performance.  Of  the  unvested  RSUs, 
approximately 32% could vest based on a fixed future date, approximately 25% and 43% could vest on performance and 
market  criteria  respectively.  The  minimum  vesting  period  for  RSUs  is  one  year.  In  May  2019,  the  Company’s 
shareholders  approved  an  amendment  to  the  LTIP  such  that  non-employee  directors  are  excluded  from  future  grants 
under the LTIP. 

Deferred Share Units 

In  May  2019,  the  Company’s  shareholders  approved  the  DSU  Plan.  The  DSU  Plan  provides  for  granting  of  DSUs  to 
non-employee  directors. DSUs vest immediately, however the Company will  issue one Common Share for each DSU 
only  after  the  non-employee  director  has  ceased  to  be  a  director  of  the  Company.  At  the  time  the  DSU  Plan  was 
approved, the Board granted 366,000 DSUs and the Company recognized $209 in DSU expense. 

The following table summarizes the DSU activity under the DSU Plan as of December 31, 2019 and changes during the 
year then ended:

During the year ended December 31, 2018, the Company granted a total of 265,000 phantom units to certain employees. 
The value of each unit is equal to the Company’s share price on the vesting date and is payable in cash. The phantom 
units vest on fixed future dates provided the recipient continues to be affiliated with Vista on those dates. Unrecognized 
compensation  expense  on  these  units  is  based  on  the  Company’s  stock  price  at  year  end.  The  Company  accounts  for 
these units as awards classified as liabilities with $26 and $23 included in current liabilities as of December 31, 2019 and

Stock  options  to  purchase  1,437,000  Common  Shares,  unvested  RSUs  representing  1,491,301  Common  Shares,  and 
vested  DSUs  representing  366,000  unissued  Common  Shares  were  outstanding  at  December  31,  2019  but  were  not 
included in the computation of diluted weighted average Common Shares outstanding because their effect would have 
been  anti-dilutive.  Stock  options  to  purchase  1,319,149  Common  Shares,  unvested  RSUs  representing  1,002,670 
Common Shares, and 6,514,625 warrants to purchase Common Shares were outstanding at December 31, 2018 but were 
not  included  in  the  computation  of  diluted  weighted  average  Common  Shares  outstanding  because  their  effect  would 
have been anti-dilutive.  

During November 2017, the Company entered into an at-the-market offering agreement (the “ATM Agreement”) with 
H. C. Wainwright & Co., LLC (“Wainwright”), under which the Company may, but is not obligated to, issue and sell 
Common Shares through Wainwright as sales manager in an at-the-market offering under a prospectus supplement to a 
base shelf prospectus for aggregate sales proceeds of up to $10,000 (the “ATM Program”). The ATM Agreement will 
remain in full force and effect until the earlier of August 31, 2020, or the date that the ATM Agreement is terminated in 
accordance with the terms therein. Offers or sales of Common Shares under the ATM Program will be made only in the 
United States  and no  offers or  sales of  Common  Shares under  the  Agreement  will  be  made  in  Canada.  The  Common 
Shares will be distributed at the market prices prevailing at the time of sale. As a result, prices of the Common Shares 
sold  under  the  ATM  Program  may  vary  during  any  period  of  distribution.  At  December  31,  2019  and  December  31, 
2018 no offers or sales had been made under the ATM Program.  

7. Commitments and Contingencies 

Our exploration and development activities are subject to various laws and regulations governing the protection of the 
environment. These laws and regulations are continually changing and are generally becoming more restrictive. As such, 
future  expenditures  that  may  be  required  for  compliance  with  these  laws  and  regulations  cannot  be  predicted.  We 
conduct our operations in an effort to minimize effects on the environment and believe our operations are in compliance 
with applicable laws and regulations in all material respects. 

Under our agreement with the Jawoyn Association Aboriginal Corporation (the “JAAC”), the JAAC will be entitled to 
an annual cash payment, or payment in kind, equal to 1% of the value of the annual gold production from the current 
mining licenses, and a 1% NSR on other metals, subject to a minimum payment of A$50 per year. In addition, we have

the JAAC holding a 10% participating interest in Mt Todd. 

8. Fair Value Accounting 

The following table sets forth the Company’s assets measured at fair value by level within the fair value hierarchy. As 
required by accounting guidance, assets are classified in their entirety based on the lowest level of input that is

Our marketable securities and investment in Midas Gold Shares and Nusantara Resources shares are classified as Level 1 
of  the  fair  value  hierarchy  as  they  are  valued  at  quoted  market  prices  in  an  active  market.  Marketable  securities  are 
included in other current assets on the Consolidated Balance Sheets for each period presented.  

The mill equipment is classified as Level 3 of the fair value hierarchy as its value at 2018 was based on an independent 
third-party  valuation.  This  valuation  was  based  on  unobservable  inputs  obtained  by  our  valuation  specialists  and 
reviewed by the Company. These inputs may change as economic and industry conditions evolve. The mill equipment is 
included in plant and equipment on the Consolidated Balance Sheets for each period presented.  

There were no material transfers between levels nor were there any changes in valuation methods in 2019.  

9. Supplemental Cash Flow Information and Material Non-Cash Transactions 

As  of  December 31,  2019  and  2018,  all  of  our  cash  was  held  in  liquid  bank deposits  and/or  government  treasury 
bills/notes in the United States. 

At December 31, 2019, the Company held 1,333,334 shares of Nusantara Resources valued at $272; comprising 666,667 
shares  received  as  part  of  the  consideration  for  amending  the  Awak  Mas  royalty  agreement,  and  666,667  shares  not 
previously given accounting recognition as the amount was considered immaterial. There were no significant non-cash 
transactions for the year ended December 31, 2018.

Valuation Allowance on Canadian and Foreign Tax Assets 

We  establish  a  valuation  allowance  against  the  future  income  tax  assets  if,  based  on  available  information,  it  is  more 
likely than not that all of the assets will not be realized. The valuation allowance of $59,886 and $56,659 at December 
31,  2019  and  2018,  respectively,  relates  mainly  to  net  operating  loss  carryforwards,  in  Canada  and  other  foreign  tax 
jurisdictions, where the utilization of such attributes is not more likely than not. The Company continually assesses both 
positive and negative evidence to determine whether it is more likely than not that deferred tax assets can be realized 
prior to their expiration.

Accounting for uncertainty in taxes 

Accounting  Standards  Codification  Topic  740  guidance  requires  that  the  Company  evaluate  all  income  tax  positions 
taken, and recognize a liability for any uncertain tax positions that are not more likely than not to be sustained by the tax 
authorities.  As  of  December  31,  2019,  the  Company  believes  it  has  no  liability  for  unrecognized  tax  positions.  If  the 
Company  were  to  determine  there  were  any  uncertain  tax  positions,  the  Company  would  recognize  the  liability  and 
related interest and penalties within income tax expense.  

Tax statute of limitations 

The  Company  files  income  tax  returns  in  Canada,  U.S.  federal  and  state  jurisdictions  and  other  foreign  jurisdictions. 
There are currently no tax examinations underway for these jurisdictions. Furthermore, the Company is no longer subject 
to Canadian tax examinations by the Canadian Revenue Agency for years ended on or before December 31, 2016 or U.S. 
federal  income  tax  examinations  by  the  Internal  Revenue  Service  for  years  ended  on  or  before  December  31,  2016. 
Some  U.S.  state  and  other  foreign  jurisdictions  are  still  subject  to  tax  examination  for  years  ended  on  or  before 
December 31, 2015. 

Although certain tax years are closed under the statute of limitations, tax authorities can still adjust losses being carried 
forward into open years.

11. Geographic and Segment information 

The Company has one reportable operating segment, consisting of evaluation, acquisition, and exploration activities. We 
evaluate,  acquire,  explore  and  advance  gold  exploration  and  potential  development  projects,  which  may  lead  to  gold 
production  or  value  adding  strategic  transactions.  These  activities  are  currently  focused  principally  in  Australia.  We 
reported no revenues during the years ended December 31, 2019 or 2018. Geographic location of mineral properties and 
plant and equipment is provided in Notes 4 and 5, respectively.  

12. Provision for Environmental Liability  

During  2016,  the  Province of  British  Columbia  Ministry  of  Energy  and  Mines  (“MEM”)  requested  that  the  Company 
prepare  and  present  to  MEM  a  reclamation  plan  for  closure  and  abandonment  of  certain  mining  claims  in  British 
Columbia which the Company had disposed of in 1996. A plan was presented to MEM and we are awaiting a formal 
response. Assuming no other potentially responsible parties are identified, we have accrued estimated reclamation and 
other related costs, as of December 31, 2019 and 2018 on an undiscounted basis.

within the time periods specified in applicable rules and forms and (ii) material information required to be disclosed in 
our reports filed under the Exchange Act is accumulated and communicated to our management, including our CEO and 
CFO, as appropriate, to allow for accurate and timely decisions regarding required disclosure.
