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

The  terms  “mineral  reserve”,  “proven  mineral  reserve”  and  “probable  mineral  reserve”  are  Canadian  mining  terms 
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 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. “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 pre-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 U.S. 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  that  any  part  of  the 
mineralized material will ever be confirmed or converted into SEC Industry Guide 7 compliant “reserves”.  Investors are 
cautioned not to assume that all or any part of the mineralized material will ever be confirmed or converted into reserves 
or that mineralized material can be economically or legally extracted. 

GLOSSARY 

“acid rock drainage (ARD)” results from the interaction of meteoric water with oxidizing sulfide minerals. 

“arsenopyrite”  means  an  iron  arsenic  sulfide.  It  is  the  most  common  arsenic  mineral  and  the  primary  ore  of  arsenic 
metal.

“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 large (greater than two millimeters in diameter) rounded 
particles.  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  the  project. The 
confidence level of the study will be higher than that of a pre-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.

“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.   

“granitoid” means a variety of coarse grained plutonic rock similar to granite, which are composed predominantly of 
feldspar or quartz.

“greywackes” means fine-grained sandstone generally characterized by its hardness, dark color and poorly sorted angular 
grains of quarts, 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 can be 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”  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 pre-feasibility or feasibility level as appropriate that include application of mining, 
processing,  metallurgical,  infrastructure,  economic,  marketing,  legal,  environmental,  social  and  governmental  factors. 
Such studies demonstrate that, at the time of reporting, extraction could reasonably be justified.  

3 

 
 
 
 
 
 
 
 
 
 
 
 
“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 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. 

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

“preliminary feasibility study”, “PFS” and “pre-feasibility study” as defined by the CIM 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  the  realistically  assumed  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 pre-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 
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.

PART I 

ITEM 1.  BUSINESS.  

Overview 

Vista  Gold  Corp.  and  its  subsidiaries  (collectively,  “Vista,”  the  “Company,”  “we,”  “our,”  or  “us”)  are  engaged  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, royalty 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.  

The  Company’s  flagship  asset  is  its  100%  owned  Mt  Todd  gold  project  (“Mt  Todd”)  in  Northern  Territory  (“NT”), 
Australia.  Completion  of  a  feasibility  study  or  the  development  of  the  project  is  not  justified  at  this  time  due  to  the 
current  low  gold  price.  With  the  completion  of  the  environmental  impact  statement  (“EIS”)  in  2014  and  the  previous 
completion of a significant amount of the project engineering and design, much of which is contained in the previously 

9 

 
 
 
 
 
 
released  preliminary  feasibility  study,  management  believes  that  the  permitting  risk  is  substantially  reduced  and  the 
potential development timeline at Mt Todd is well defined. We believe that we are well positioned, subject to sustained 
improvement in gold prices, to move forward quickly with the completion of the Mt Todd feasibility study. At the time 
the  May  2013  PFS  was  completed,  because  of  the  high  level  of  detail  in  the  work  completed  for  the  study,  it  was 
estimated that the feasibility study could be completed within six months of its start at a cost of approximately $2,500.  

We do not currently generate cash  flows from  mining operations. The prices for gold equities, particularly those  with 
early stage projects, have decreased significantly during the past few years, and capital raising on reasonable terms has 
become more difficult for mining companies which do not have producing assets.  These market conditions are expected 
to  continue  for  the  foreseeable  future,  and  could  affect  our  ability  to  raise  sufficient  capital  to  advance  Mt  Todd  on 
reasonable terms, if at all.   

Since  2013  we  have  raised  sufficient  cash  to  operate  our  business  without  share  dilution,  and  we  have  significantly 
reduced our costs to strengthen our balance sheet and mitigate the effects of these difficult markets. We believe we have 
sufficient  cash  to  fund  our  currently  planned  programs  into  2018,  while  retaining  opportunities  to  access  additional 
financing  from  non-dilutive  sources  such  as  the  sale  of  our  used  mill  equipment  and  monetization  of  other  non-core 
assets.  

We  plan  to  continue  to  evaluate  and  execute  programs  that  could  position  us  to  quickly  advance  Mt  Todd  to 
development when economic conditions permit. In addition, with our improved treasury and strong management team 
we are in a position to judiciously evaluate and pursue other near-term value creating opportunities. 

Vista  Gold  Corp.  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 
Gold  continued  from  British  Columbia  to  the  Yukon  Territory,  Canada  under  the  Business  Corporations  Act  (Yukon 
Territory).    On  June  11,  2013,  Vista  Gold  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

Corporate Organization Chart 

The name, place of incorporation, continuance or organization and percent of equity securities that we own or control as 
of February 15, 2016 for each of its subsidiaries is set out below.  

Employees 

As of December 31, 2015, we had 13 employees globally. In addition, we use consultants  with specific skills to assist 
with various aspects of our project evaluation, due diligence, corporate governance and property management. 

Geographic and Segment Information 

We  have  one  reportable  segment,  consisting  of  evaluation,  acquisition  and  exploration  activities  which  are  focused 
principally in Australia and North America.  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 
focused  principally  in  Australia  and  North  America.  We  reported  no  operating  revenues  during  the  years  ended 
December 31, 2015 and 2014. 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 

Significant Developments in 2015 

In 2015, the Company received an A$13,470 ($10,220) Research & Development (“R&D”) Tax Incentive refund, net of 
costs to prepare and file. These amounts were paid under the Australian Government’s R&D Tax Incentive Program, a 
program  designed  to  encourage  industry  to  engage  in  R&D  activities  that  benefit  Australia;  and  relate  to  costs  we 
incurred  during  the  2012  and  2013  fiscal  years  for  qualifying  R&D  programs.  This  R&D  Tax  Incentive  program  is  a 
self-assessment  process,  and  as  such,  the  Australian  Government  has  the  right  to  review  the  qualifying  programs  and 
expenditures for a period of four years.        

In March 2015, we sold 8,000,000 Midas Gold Corp. common shares (“Midas Gold Shares”) for net proceeds of $2,772.

In January 2015, the Company amended the payment terms for the sale of its 100% interest in the Los Cardones gold 
project in Baja California Sur, Mexico.  Under the amended terms the Company accepted a final payment of $2,994, net 
of legal costs, for the project.  

See  the  section  heading  “Item  7.  Management’s  Discussion  and  Analysis  of  Financial  Condition  and  Results  of 
Operations – Financial Position, Liquidity and Capital Resources”, below.   

Reclamation 

We  generally  will  be  required  to  mitigate  long-term  environmental  impacts  by  stabilizing,  contouring,  re-sloping  and 
revegetating 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  Vista’s  involvement  with  the  project  remains  the  responsibility  of  the  NT 
Government until 30 days after 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 will not give such notice until a production decision has 
been  made, the project is fully permitted to construct  the  mine, and the necessary financing for construction has been 
arranged.   

Government Regulation 

Our  exploration  and  development  activities  are  subject  to  various  national,  state,  provincial  and  local  laws  and 
regulations  in  the  United States,  Mexico,  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 that 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.  Management  of  the  Company  is  not  aware  of  any  current  orders  or 
directions relating to us with respect to the foregoing laws and regulations.  

Australia Laws  

Mineral projects in the Northern Territory are subject to Australian federal and Northern Territory laws and regulations 
regarding environmental matters and the discharge of hazardous wastes and materials. As with all mining projects, Mt 
Todd would be expected to have a variety of environmental impacts should development proceed. 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  Australia,  environmental  legislation  plays  a  significant  role  in  the  mining  industry. 
Various  environmental  documents,  such  as  the  Mt  Todd  EIS,  covering  studies  on  inter  alia,  air,  water,  pollution, 
hazardous and toxic wastes, reclamation of mining area, etc., must be prepared and submitted to the Northern Territory 
Minister  for  Mines  &  Energy  and  Environment  and  the  Australian  Government  Minister  For  Sustainability, 
Environment,  Water,  Population  and  Communities  for  approval.    During  September  2014,  the  EIS  for  Mt  Todd  was 
approved.  The Environmental Protection Agency of the Northern Territory Government (“NTEPA”) has advised that it 
has assessed the environmental impacts of the Mt Todd gold mine and concluded that it can proceed, subject to a number 
of  recommendations  which  are  outlined  in  the  assessment  report.  We  must  also  comply  with  Aboriginal  heritage 
legislation  requirements,  which  require  heritage  survey  work  to  be  undertaken  prior  to  the  commencement  of  mining 
operations. All these recommendations/conditions  may result in the occurrence of significant pre-production costs and 
may delay potential production at Mt Todd. 

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 

12 

 
 
 
 
 
 
 
  
 
 
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,  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,  and  additional  regulatory  requirements  could  impact  the 
economics of our projects. 

During 2015, none of our project sites had any material non-compliance occurrences with any applicable environmental 
regulations.   

Competition 

We compete with other mining companies in connection with the acquisition, exploration, financing and development of 
gold properties. There is competition for the limited number of gold acquisition and exploration opportunities, some of 
which is with other companies having substantially greater financial resources than we have. As a result, we may have 
difficulty  acquiring  attractive  gold  projects  at  reasonable  prices.  We  use  consultants  and  compete  with  other  mining 
companies for the man hours of consulting time required to complete our studies.  We also compete with other mining 
companies for 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.

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 immaterial 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 operating 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.  There can be no assurance that the results 
of the feasibility study will be positive or that such study will be completed when expected.  If the Mt Todd feasibility 
study is favorable, and if the project can be financed, there is no assurance that actual production rates, revenues, capital 
and operating costs at Mt Todd will not vary unfavorably from the estimates and assumptions included in the 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  will 
depend on several factors,  including a  favorable feasibility study, acquisition of  the requisite permits,  macroeconomic 
conditions,  and  future  gold  prices.  Uncontrollable  factors  such  as  lower  gold  prices,  unanticipated  operating  or 
permitting challenges, perception of environmental impact, illiquidity in the debt markets or a further dislocation in the 
gold mining equity markets as experienced in recent years, could prohibit our ability to finance Mt Todd on acceptable 
terms, if 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 we provide 30 days notice to NT Government of our intention to take over and 
assume the management, operation and rehabilitation of Mt Todd.  At that time, we will be required to provide a bond in 
a form satisfactory to the NT Government (in whose jurisdiction Mt Todd is located) that would cover the prospective 
expense of the reclamation of 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 will have no reserves under SEC Industry Guide 7 and NI 43-
101, which would result in an impairment of the carrying value of the project. 

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

Delays in commencement of construction could result from factors such as availability and performance of engineering 
and  construction  contractors,  suppliers  and  consultants;  availability  of  required  equipment;  and  availability  of  capital. 
Any delay in the performance of any one or more of the contractors, suppliers, consultants 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.   

14 

 
 
 
 
 
 
 
 
 
 
 
 
Increased costs could impede our ability to become profitable. 

Costs at any particular mining location frequently 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 price of commodities, fuel, electricity, operating supplies and labor. These 
costs are at times subject to volatile price movements, including increases that could make future production at Mt Todd 
less  profitable  or  uneconomic.  This  could  have  a  material  adverse  effect  on  our  financial  condition,  cash  flows  and 
results of operations.  

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

Water at Mt Todd is expected to be provided from a fresh  water reservoir  which is fed by seasonal rains. Insufficient 
rainfall,  or  drought-like  conditions  in  the  area  feeding  the  reservoir  could  limit  or  extinguish  this  water  supply,  and 
insufficient water resources may not be available leading to operations stopping until the water supply is replenished.   

We could be subject to litigation 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 required to respond to or defend against these claims which will divert resources away from our principal business. 
There  can  be  no  assurance  that  our  defense  of  such  claims  would  be  successful,  and  we  may  be  required  to  make 
material  settlements.  This  could  have  a  material  adverse  effect  on  our  financial  condition  and  cash  flows,  results  of 
operations, 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”)  which  may  earn  the  right  to 
obtain a majority 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 difficulties, 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  co-
venturers.   

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

Our property and royalty interests are subject to environmental regulation. Environmental legislation is becoming more 
restrictive in some countries or jurisdictions in a manner that will require stricter standards and enforcement, increased 
fines and penalties for non-compliance, more stringent environmental assessments of proposed projects and a heightened 
degree  of  responsibility  for  companies  and  their  officers,  directors  and  employees.  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 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.

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 perhaps reduce 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.  

Our  property  and  royalty  interests  in  Mexico  and  Indonesia  are  subject  to  risks  from  political  and  economic 
instability.  

We have property and royalty interests in Mexico and Indonesia that may be affected by risks associated with political or 
economic instability in those countries. The risks include, but are not limited to, military repression, extreme fluctuations 
in  currency  exchange  rates,  labor  instability  or  militancy,  mineral  title  irregularities  and  high  rates  of  inflation.  In 
addition, changes in mining or investment policies or shifts in political attitude in these countries may adversely affect 
our  business.  We  may  be  affected  in  varying  degrees  by  government  regulation  with  respect  to  restrictions  on 
production,  price  controls,  export  controls,  income  taxes,  expropriation  of  property,  maintenance  of  claims, 
environmental legislation, land use, land claims of local people, water use and mine safety. The effect of these factors 
cannot be accurately predicted. 

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 on a daily basis 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 positions taken by significant investors or traders in gold; 
the relative strength of the U.S. dollar; 
expectations of the future rate of inflation; 
interest rates; 
changes to economic activity 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; 
reduce our existing estimated mineral resources and reserves by removing ores from these estimates that could 
not be economically processed at the lower gold price;  
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. 

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 market and industry factors including the 
price of gold, we believe the current market value of our common stock does not reflect the fair value of the Company’s 

16 

 
 
 
 
 
 
 
 
 
 
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, 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. 

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/or  debt,  and  selling  non-core 
assets. In addition, during 2015 we received refunds related to the Australian Government’s Research and Development 
Tax Incentive Program (“R&D Refunds”).    

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 R&D 
Refunds. We expect to continue to incur losses for the foreseeable future. We have no history of paying cash dividends 
and we do not expect to pay cash dividends or to make any similar distribution in the foreseeable future. 

We may be unable to raise additional capital on favorable terms, if 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, and/or to acquire attractive gold projects, we will 
have to raise additional funds from the sale of non-core assets and / or external sources. There can be no assurance that 
we  will  be  successful  in  selling  non-core  assets  or  that  additional  financing  will  be  available  at  all  or  on  acceptable 
terms. If we cannot raise sufficient additional financing, we may have to substantially reduce or cease operations. 

Our exploration and development activities or any acquisition activities may not be commercially successful. 

Substantial  expenditures  are  required  to  acquire  gold  properties,  to  establish  mineral  reserves  through  drilling  and 
analysis,  to  develop  metallurgical  processes  to  extract  metal  from  the  ore  and  to  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, established or discovered will be in sufficient quantities to justify commercial operations or that the 
funds invested in them will ever be recovered. 

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 
mining companies with greater financial and technical resources than ours.  We compete with other mining companies 
for attractive  mining claims,  for capital,  for equipment and supplies,  for outside services and  for qualified  managerial 
and  technical  employees.  Competition  for  capital  has  reduced  the  amount  of  capital  available  and  increased  the 
associated cost of raising capital.  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,  which  is  what  we  have  done  at  Mt  Todd,  for 
example. 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 
results of operations, cash flows, financial condition and corporate reputation.    

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  not  to  have  insurance  for  certain  risks  because  of  the  high  premiums  associated  with  insuring  those  risks  or  for 

17 

 
 
 
 
 
 
 
 
 
 
 
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 could result in significant losses that could materially adversely 
affect our financial condition and our ability to fund our business.   

Our stock price may be volatile and your investment in our common stock could suffer a decline in value.  

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

• 
• 

• 
• 
• 
• 
• 
• 

changes in financial estimates by us or by any securities analysts who might cover our stock; 
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 stock, 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 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.  

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 during 
the taxable year ended December 31, 2015, 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.” 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.

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 an ore deposit may differ  materially  from the 
estimates. 

Feasibility studies are estimates only and subject to uncertainty.  

Feasibility  studies  are  used  to  determine  the  economic  viability  of  an  ore  deposit,  as  are  pre-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 pre-feasibility studies and plus or minus 35-40% for 
preliminary  economic  assessments.  These  levels  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 differ materially from these estimates.  

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  pressure  to  increase  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  financial 
condition.  

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. 

19 

 
 
 
 
 
 
 
 
 
 
 
 
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  future  international 
mining operations.

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. 

Cautionary  Note  to  U.S. 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 U.S. 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. U.S. 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  U.S. 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  pre-
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. U.S. 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. 

Please see “Cautionary Note to U.S. Investors Regarding Estimates of Measured, Indicated and Inferred Resources and 
Proven and Probable Reserves” above for further discussion on the differences between terms under NI 43-101 and SEC 
Industry Guide 7. 

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

Units of measurement are reported by the qualified person in compiling reports on a project vary by country, Imperial 
units  for  properties  in  the  U.S.  and  metric  units  for  properties  outside  the  U.S.  We  use  the  units  of  measurement  as

reported  by  the  qualified  persons  in  their  respective  reports,  regardless  of  property  location,  in  order  to  correspond  to 
those units as reported by the qualified persons. 

Mt Todd Gold Project, Northern Territory, Australia 

Property Description and Location 

In  2006,  we  acquired  the  concession  rights  to  Mt  Todd  from  the  Deed  Administrators  for  Pegasus  Gold  Australia 
Pty Ltd.  (“Pegasus”),  NT  Government  and  the  Jawoyn  Association  Aboriginal  Corporation  (“JAAC”).  In  2014,  the 
agreement was extended through the end of 2018. Mt Todd was an operating mine in the late 1990’s, 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  250  kilometers 
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. 

in 

the  Batman  deposit  at 

in  sheeted  veins  within  silicified 
Gold  mineralization 
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 1.6 km 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  project  occurs 

The  Mt  Todd  Base  Case  (defined  below)  is  designed  to  be  a  conventional,  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  large 
comminution  circuit  consisting  of  a  gyratory  crusher,  two  cone  crushers,  two  High  Pressure  Grinding  Roll  (“HPGR”) 
crushers, and three ball 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  1990’s.    Liability  for  the  reclamation  of  the 
environmental  conditions  existing  prior  to  Vista’s  involvement  with  the  project  remains  the  responsibility  of  the  NT 
Government until 30 days after 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 will not give such notice until a production decision has 
been  made, the project is fully permitted to construct  the  mine, and the necessary financing for construction 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.

Total land holdings controlled by Vista Gold Australia are approximately 140,000 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 follows.  Substantially all of the estimated mineral resources at Mt Todd are located in the Batman pit.

The surface land in the area of the contiguous MLs and ELs (excluding EL28321) 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 the use of and access to the land. 

In 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% NSR royalty on other metals, subject to a minimum payment of A$50 per year. 

We are required annually to submit a Mine Management Plan 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 in the 1990’s, 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 
project  access  control  point,  a  small  shop  and  office,  and  the  flotation  plant  building,  as  well  as  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 and heap leach pad have resulted in acid rock 
drainage  which  is  controlled  to  the  extent  possible  through  collection  in  retention  ponds,  storage,  pH  adjustment  and 
controlled release of acidic or treated water into the Edith River when water levels were high enough, in accordance with 
the waste discharge license.   

Water Treatment 

We completed the installation of a lime silo and slaker for water treatment in 2009. The treated water was initially stored 
in the existing  tailings impoundment  facility, but the above average rainfall experienced in the 2010-2011  wet  season 
raised the  level of  water in the tailings impoundment  facility  which resulted in  the  suspension of  water treatment.  In 
2011,  we  started  pumping  water  from  the  tailings  impoundment  facility  into  the  Batman  pit.  Following  extensive 
chemical  and  toxicological  testwork,  in  2012  we  received  authorization  from  the  NT  Government  to  in  situ  treat  the 
water stored in the Batman Pit to  neutralize the acidity and to precipitate the contained  metals. In February 2013,  we 
received  a  waste  discharge  license  from  the  NT  Government  that  authorized  the  release  of  treated  water  from  the  Mt 
Todd  site  during  the  wet  season  in  accordance  with  higher  environmental  protection  standards.  We  have  operated  in 
compliance with the new standards. We will have to dewater substantially the entire pit before mining operations can be 
started.  

Geology, Mineralization, and Exploration 

Mt Todd is situated within the southeastern portion of the Early Proterozoic Pine Creek Geosyncline. Meta-sediments, 
granitoids, 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 moderately 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 1789 Ma to 1730 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 2,200  meters in length 
by 365 to 450 meters in true 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.  

24 

 
 
 
 
 
 
 
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. 

Preliminary Feasibility Study 

An amended and restated pre-feasibility study (“PFS”) for Mt Todd pursuant to NI 43-101 was filed on SEDAR on July 9, 
2014, and is entitled “NI 43-101 Technical Report - Mt Todd 50,000 tpd Preliminary Feasibility Study – Northern Territory, 
Australia” with an effective date of July 7, 2014.  This PFS is based on the same scientific and technical data as in the May 
2013 PFS.  

The PFS evaluates two development scenarios including a 50,000 tpd project that develops more of the Mt Todd resource 
(the “Base Case”) and generates a larger Net Present Value (“NPV”) and a smaller and higher-grade 33,000 tpd project that 
focuses on maximizing internal rate of return and operating margins (the “Alternate Case”).  

Highlights of the 50,000 tpd Base Case include: 

• 

• 

• 

• 
• 

• 

estimated measured and indicated mineral resource categories of 7.40 million ounces of gold (280 million tons 
at 0.82 g Au/t) and estimated proven and probable mineral reserves of 5.90 million ounces of gold (223 million 
tonnes at 0.82 g Au/t) at a cut-off grade of 0.40 g Au/t (1); 
average  annual  production  of  369,850  ounces  of  gold  per  year  over  the  mine  life,  including  average  annual 
production of 481,316 ounces of gold per year during the first five years of operations; 
life of mine average cash costs of $773 per ounce, including average cash costs of $662 per ounce during the 
first five years of operations; 
a 13 year operating life; 
after-tax  NPV5%  of  $591.3  million  and  internal  rate  of  return  of  15.9%  at  $1,450  per  ounce  gold  prices, 
increasing to $876.6 million and 21.1%, respectively, at $1,600 per ounce gold prices; and 
initial capital requirements of $1,046 million. 

Highlights of the 33,000 tpd Alternate Case include: 

• 

• 

• 

• 
• 

• 

estimated proven and probable  mineral reserves of 3.56  million ounces of  gold (124 million tonnes at 0.90 g 
Au/t) at a cut-off grade of 0.45 g Au/t(1); 
average  annual  production  of  262,826  ounces  of  gold  per  year  over  the  mine  life,  including  average  annual 
production of 294,502 ounces of gold per year during the first five years of operations; 
life of mine average cash costs of $684 per ounce, including average cash costs of $676 per ounce during the 
first five years of operations; 
an 11 year operating life; 
after-tax  NPV 5%  of  $440.2  million  and  internal  rate  of  return  of  16.9%  at  $1,450  per  ounce  gold  prices, 
increasing to $615.6 million and 21.4%, respectively, at $1,600 per ounce gold prices; and  
Initial capital requirements of $761 million.

The following table presents a breakdown of Base Case operating costs. The project includes a 76MW gas-fired power 
plant in the initial capital.  The Base Case project consumes all power generated during the operating life. Self-generated 
power creates significant savings in operating costs compared to a grid-sourced power solution. During the four years of 
reclamation  and  closure,  the  PFS  assumes  we  will  continue  to  generate  power  and  will  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 50,000 tpd Base Case  mine plan contains 209.5  million tonnes of  material  mined  from  the Batman open pit plus 
13.4 million tonnes of material from the existing heap leach pad that is processed through the mill at the end of the mine 
life.  Together, 222.8 million tonnes of material containing 5.901 million ounces of gold at an average grade of 0.82 g 
Au/t  are  processed  over  the  13  year  operating  life.   Total  gold  recovered  is  expected  to  be  4.808  million 
ounces.  Average annual gold production over the life of mine is 369,850 ounces, averaging 481,316 ounces during the 
first  five  years  of  operations,  with  580,472  ounces  produced  in  the  first  year  of  operations.   Commercial  production 
would begin following two years of construction and commissioning.

Alternative Case Scenario Presented in PFS 

The key differences between the Base Case and the alternative case include: 

• 

• 

a 33,000 tpd processing facility versus a 50,000 tpd facility in the Base Case with associated lower mining rates 
and a smaller fleet; and 
an  ultimate  pit  design  based  on  a  reserve  pit  shell  of  $925/oz  versus  $1,360/oz  in  the  Base  Case  and  the 
application of a higher cut-off grade (0.45g Au/t versus 0.40g Au/t).

The 33,000 tpd Alternate Case mine plan contains 110.4 million tonnes of material mined from the Batman open pit plus 
13.4 million tonnes of material from the existing heap leach pad that is processed through the mill at the end of the mine 
life.  Together, 123.7 million tonnes of material containing 3.562 million ounces of gold at an average grade of 0.90 g 
Au/t  are  processed  over  the  11  year  operating  life.    Total  gold  recovered  is  expected  to  be  2.891  million  ounces.  
Average annual gold production over the life of mine is 262,826 ounces, averaging 294,502 ounces during the first five 
years of operations, with 417,166 ounces produced in the first year of operations.  Commercial production would begin 
following two years of construction and commissioning.

Metallurgy, Processing and Infrastructure 

Our metallurgic test work programs support: (1) ore hardness estimates at the Batman deposit that are consistent and do 
not  change  at  depth;  (2)  the  selection  of  HPGR  technology  as  part  of  the  comminution  circuit;  (3)  estimated  gold 
recovery rates based on optimized grind size and leach conditions; and (4) the processing of material from the historic 
heap leach pad at the end of the proposed mine life. 

Ore Hardness 

Samples  used  for  the  test  work  program  were  sourced  from  eight  holes  from  the  Company's  2010  and  2011  drilling 
program  that  were  oriented  to  intersect  the  main  Batman  deposit  beneath  the  existing  pit  and  are  believed  to  be 
representative of the material within the limits of the preliminary feasibility pit. 

Twenty  of  the  samples  were  subjected  to  Bond  ball  mill  work  index  (“BWi”)  tests,  the  SMC  Test  (drop-weight  and 
specific  gravity tests) as  well as  Compressive  Strength Tests and Crushing Work Index tests.  The results of the BWi 
tests  show  an  average  BWi  value  of  25  kWh/t  with  a  maximum  value  of  28.2  kWh/t  and  a  minimum  value  of  23.6 
kWh/t. 

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 at the Batman deposit does not change at depth. 

This  test  work  validates  the  Company’s  prior  test  work  and  supports  Vista's  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 Selection 

The  proposed  Base  Case  comminution  circuit  incorporates  the  use  of  a  large  gyratory  crusher  and  two  large  cone 
crushers for the primary and secondary stages, respectively, and contemplates the use of two HPGRs as the third-stage of 
the crushing circuit.  Much of our test work has focused on evaluating and confirming the use of HPGRs. 

Initially, we ran a series of parallel tests comparing a semi-autogenous grinding (“SAG”)/ball mill circuit with an HPGR 
crushing and ball mill circuit.  Based on the test work completed, HPGR technology was selected.  Industry experience 
has shown HPGRs to produce micro-fracturing in particles that reduce the overall particle strength and generate a greater 
distribution of fine material in the ball mill feed, reducing downstream ball mill energy requirements.  The material at 
the  Batman  deposit  consists  of  silicified  greywackes/shales/siltstones  and  test  work  has  shown  the  HPGRs  tend  to 
fracture  material  at  the  Batman  deposit  along  the  bedding  planes  more  than  micro-fracturing.   The  result,  however,  is 
consistent  with  other  industry  HPGR  applications  in  that  the  HPGR  product  produces  a  lower  BWi  feed  for  the  ball 
mills.  The test results indicate the SAG mill circuit produced a product with an average BWi of 26.4 kWh/t compared to 
the HPGR crushed product with an average BWi of 24.8 kWh/t, a reduction of over 6%. 

Additionally, material crushed in the HPGR test resulted in approximately 10% of the HPGR product being fine enough 
to by-pass the ball mills entirely and proceed straight to the leach circuit.  Vista has incorporated this HPGR advantage 
in its comminution circuit design. 

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/ball  mill  circuit  to  generate  a  P80  passing  90  μm 
product.   The  assessment  concluded  that  the  3-stage  HPGR/ball  mill  circuit  has  a  significantly  lower  specific  energy 
requirement than the primary/SAG/ball mill option and that a finer grind size can be achieved with the HPGR crushed 
material compared to conventionally crushed material ground for the same period of time. 

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

Gold Recoveries 

Our  focus  was  to  solve  the  high  reagent  consumption,  poor  gold  recovery  and  copper  leaching  issues  encountered  by 
previous  operators.   Historic  core  samples  indicated  the  presence  of  cyanide  soluble  secondary  copper  mineralization 
(chalcocite and bornite) in material at the Batman deposit, and as such, our initial focus was to develop a flowsheet that 
incorporated the production of a copper concentrate. 

However our drill programs from 2007–2012 indicated a significant change in the mineralogy of material at the Batman 
deposit  with  depth  with  copper  mineralogy  changing  from  cyanide  soluble  secondary  copper  to  non-cyanide  soluble 
primary copper mineralization (chalcopyrite).  The change in mineralogy occurs at approximately 40 meters below the 
existing  surface  and  the  majority  of  the  ore  containing  cyanide  soluble  secondary  copper  was  mined  by  previous 
operators.  As a result, more than 96% of material at the Batman deposit contains low-to-non-cyanide soluble primary 
copper  mineralization.   Therefore,  our  recovery  circuit  has  been  simplified  and  focuses  only  on  recovering  gold  from 
material at the Batman deposit through a conventional CIP circuit. 

The remainder of our test work relating to gold recovery focused on optimal grind size, pre-conditioning of ore with lime 
(to reduce cyanide consumption), the identification of a reagent to suppress copper leaching (lead nitrate was selected), 
and optimal cyanide concentration. 

After determining the optimal leach conditions, 99 samples covering a range of head grades from throughout the Batman 
deposit were subjected to leach tests resulting in gold extraction between 75% and 85%, with an average of 81.7%, net 
of solution losses.  Cyanide consumption was estimated at 0.77kg/t and lime consumption was estimated at 0.91kg/t.

This test work validates our prior recovery estimates (82%), indicates minimal gold recovery variability throughout the 
Batman deposit, and supports Vista's recovery plant design utilizing a conventional, industry-proven, CIP circuit. 

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 on 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 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. 

We subsequently submitted two heap leach variability composites and two drill hole composites from the leach pad for 
CIP cyanidation leach test work.  The samples were ground to P80 passing 90 μm and pre-treated with lime and 100g/t 
of lead nitrate to suppress copper leaching.  The material was then leached for 24 hours.  These results support recovery 
rates of 70% for this material when processed through the CIP plant. 

The 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 reduces the scope of related reclamation by limiting the scope of reclamation to the pad liner 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  overruns  in  the 
mining industry over the last decade.  Existing mining infrastructure items include: 

• 

• 

• 

• 
• 
• 

an existing tailings storage facility that will receive two raises and is expected to contain the initial 62 million 
tonnes of material processed with two operating raises of the embankment; 
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. 

Other benefits of Mt Todd’s NT location include: 

• 
• 
• 

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

Permitting 

In June 2013, we completed and submitted an initial EIS to the NTEPA for review. This submission started concurrent 
agency review and public consultation periods, the latter of which completed during August 2013.  Following closure of 
the public consultation and agency review periods, the NTEPA provided a consolidated set of comments to us, which we 
responded to in a final EIS which was submitted for approval during November 2013. During September 2014, the EIS 
was approved. In its formal notification to us (the “Assessment Report”), the NTEPA has advised that it has assessed the 
environmental  impacts  of  the  Mt  Todd  gold  mine  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.   Four  of  these  recommendations  must  be  addressed 
under  the  federal  Environmental  Protection  and  Biodiversity  Conservation  Act  1999  (“EPBC  Act”)  as  they  relate 
directly to the Gouldian Finch.  See ‘2015 Programs and 2016 Plans’ below. 

Exploration Potential 

Based on airborne geophysical survey data, we have identified five 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 PFS, as part of the overall project sampling and assaying methodology.  

Based  on  Tetra  Tech’s  resource  analysis,  at  a  cut-off  grade  of  0.50  g  Au/t,  under  SEC Industry  Guide  7 guidelines, 
mineralized material for the Quigleys deposit is estimated at 6,076,000 tonnes grading 0.92 g Au/t. 

Under CIM Definition Standards, at the same cut-off grade of 0.50 g Au/t, measured mineral resources are estimated at 
511,000 tonnes grading 1.04 g Au/t, indicated mineral resources are estimated at 5,565,000 tonnes grading 0.91 g Au/t 
and inferred mineral resources are estimated at 9,416,000 tonnes grading 0.95 g Au/t. Cautionary Note to U.S. Investors: 
see  the  section  heading  “Cautionary  Note  to  United  States  Investors  Regarding  Estimates  of  Measured,  Indicated  and 
Inferred Resources and Proven and Probable Reserves” above.     

2015 Programs and 2016 Plans 

The  focus  of  our  activities  at  Mt  Todd  during  2015  was  principally  on  water  management  and  related  activities; 
permitting,  specifically  the  authorization  required  under  the  EPBC  Act  as  it  relates  to  the  Gouldian  Finch;  and 
identifying and evaluating project optimization opportunities.  

The work to obtain the authorization required under the EPBC Act was well advanced through 2015 and the request for 
authorization was submitted in December. We expect that this authorization will be granted in the first half of 2016.   

Through 2015 we completed proof-of-concept drilling programs at our Wandie and Snowdrop targets on the EL’s.  A 
total of 6 core holes were drilled, three on each target (280 meters at Wandie and 750 meters at Snowdrop) to test targets 
identified based on geophysical and soil sampling anomalies. While we did not intersect any significant, sustained gold

mineralization, we have learned more about the geologic settings of these two distinct targets which could form the basis 
for future programs, subject to the availability of funding.  

In  addition  we  drilled  two  deep  holes  to  the  south  of  the  Batman  deposit  to  test  a  geologic  hypothesis  related  to  the 
plunging higher-grade zone at the core of the deposit. This hole encountered the intrusive contact several hundred meters 
higher than expected, which has caused us to reevaluate our interpretation of the intrusive contact and the potential for a 
deep, high grade extension of the deposit. Because this drilling was undertaken approximately 200 meters south of the 
proposed pit limits and almost 600 meters deeper than that the proposed pit, it has no impact on our current  geologic 
interpretation of the Batman deposit.  

Given the history of Mt Todd, the general lack of capital for new gold mining projects and our continued goal to develop 
a  project  that  will  appropriately  reward  our  shareholders,  we  believe  an  unlevered  after  tax  internal  rate  of  return  in 
excess  of  20%  will  be  required  for  development  of  Mt  Todd.  Accordingly,  we  continue  to  closely  monitor  the 
macroeconomic  factors that affect the Mt Todd project IRR. These include the gold price,  weakness in the  Australian 
dollar, global softening of mining and process equipment prices, growing availability of skilled mining professionals in 
Australia as a result of softening demand for commodities such as iron ore and coal and weak global economic growth. 
Currently,  the  USD:AUD  exchange  rate  has  stabilized  in  the  $0.70  range.    With  60%-70%  of  the  project  capital  and 
operating costs denominated in Australian dollars, this exchange rate has a material favorable impact on the economics 
of Mt Todd significantly mitigating the negative effects of the current lower gold price.  

We plan to continue our focus on Mt Todd and have retained a team of experts to review the key areas of the project, 
concentrating on metallurgical recovery, process engineering and plant design, pit slope rock mechanics, mine plans and 
scheduling,  and  the  gas-fired  power  plant,  and  to  make  recommendations  that  may  lead  to  improved  project 
economics.  In addition, subject to availability of funding, we continue to consider other selected discretionary programs, 
mainly consisting of technical studies and exploration programs, that could be expected to add value to Mt Todd and 
better position us to quickly advance the project to development when economic conditions warrant. 

Mt Todd is without known mineral reserves under SEC Industry Guide 7. 

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

During  April  2014,  Minera  Gold  Stake  S.A.  de  C.V.  (“MGS”),  Vista’s  wholly-owned  subsidiary,  entered  into  a 
definitive option agreement (the “Option Agreement”) to option a 70% interest in the Guadalupe de los Reyes gold/silver 
project  in  Sinaloa,  Mexico  to  Great  Panther  Silver  Limited  (formerly  Cangold  Limited)  (“Great  Panther”)  for 
consideration of  $5,000 in five payments over a three-year period, with payments totaling $1,000 in the first year ($500 
received in 2014 and $496 net of legal costs was received in March 2015), $1,500 due in February 2016 (postponed from 
January  2016)  and  $2,500  due  in  January  2017.  The  Option  Agreement  provided  that  all  cash  payments  are  non-
refundable and optional to Great Panther, and in the event Great Panther failed to pay any of the required amounts on the 
scheduled dates or failed to comply with its other obligations, the Option Agreement would terminate and Great Panther 
would have no interest in the Guadalupe de los Reyes gold/silver project. 

On February 25, 2016 Vista received notification from Great Panther that it is terminating the Option Agreement and the 
$1,500  option  payment  due  in  February  2016  was  not  made.    Pursuant  to  the  terms  of  the  Option  Agreement,  Vista 
retains all amounts already paid by Great Panther and 100% of the Guadalupe de los Reyes gold/silver project.  

We do not consider Guadalupe de los Reyes gold/silver project a material project. We intend to seek partners to advance 
the project. 

Guadalupe de los Reyes is without known mineral reserves under SEC Industry Guide 7. 

Los Cardones Gold Project  

In  October  2013,  we  sold  our  100%  debt  and  equity  participation  in  the  Los  Cardones  gold  project  located  in  Baja 
California  Sur,  Mexico  (“Los  Cardones  Sale”)  to  Invecture  Group,  S.A.  de  C.V.  (“Invecture”)  and  RPG  Structured 

34 

 
 
 
 
 
 
 
 
 
 
 
Finance  S.a.R.L.  (together,  the  “Purchasers”)  for  a  total  of  $13,000  ($7,000  of  which  was  paid  in  October  2013  and 
$6,000 was originally payable January 2014 (the “Subsequent Payment”) subject to the Purchasers’ option to elect to not 
make the Subsequent Payment).  In 2014, the due date for the Subsequent Payment was extended to January 30, 2015 for 
additional consideration of $500 payable. In October 2014, Invecture announced that the Los Cardones gold project, had 
been suspended because the conditions for its development were not favorable at that time, which introduced substantial 
doubt that the Subsequent Payment would be made. After making this announcement, there were no apparent significant 
favorable  changes  to  incentivize  Invecture  to  lift  the  suspension.  In  January  2015,  we  agreed  to  amend  the  payment 
terms (the “Amendment”) of the Los Cardones Sale. Under the Amendment, the Company received a payment of $2,994 
net of legal costs from the Purchasers as full and final payment for 100% of the Company’s interest in the project, which 
resulted in a realized gain of approximately $1,958.  
.  
Long Valley Gold Project, California  

We acquired the Long Valley gold project in January 2003. The property consists of 95 contiguous, unpatented mining 
claims that cover an area of approximately 1,963 acres. The surface rights covering the area of the claims are owned by 
the U.S. government, and are subject to a surface grazing lease. The project is subject to a 1% NSR royalty.  

Because  of  other  priorities,  we  have  no  immediate  plans  for  developing  the  Long  Valley  gold  project,  and  it  is 
considered an immaterial project to the Company at this time. The Long Valley gold project is without known mineral 
reserves under SEC Industry Guide 7. 

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 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 DISCOSURES. 

We consider health, safety and environmental stewardship to be a core value for 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,  2015,  our  U.S 
exploration properties 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.

Securities Authorized for Issuance under Equity Compensation Plans 

See “Part III Item 11. Executive Compensation” for information relating to our equity compensation plan. 

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) is  resident  solely  in  the  United States,  (ii)  is  entitled  to  the  benefits  of  the 
Convention, (iii)  holds all Common Shares as capital property, (iii) holds no Common Shares that are “taxable Canadian 
property” (as defined in the Canadian Tax Act) of the holder, (iv) deals at arm’s length with and is not affiliated with

Vista Gold, (v) does not and is not deemed to use or hold any Common Shares in a business carried on in Canada, and 
(vi) 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) may not in all circumstances be regarded by the Canada Revenue Agency (the “CRA”) as 
entitled  to the benefits of the Convention. Members of or  holders of an interest in such an entity that  holds  Common 
Shares should consult their own tax advisers regarding the extent, if any, to which the CRA will extend the benefits of 
the Convention to the entity in respect of its Common Shares. 

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 (i.e. speculation), 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 constitute “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 true: 

(i) 

the holder or any one or more persons with whom the holder does not deal at arm’s length owned, alone or in 
any combination, 25% or more of the issued shares of any class of the capital stock of Vista Gold at any time in 
the 60 months preceding the particular time; 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 so defined), or options or interests therein, at any 
time in the 60 months preceding the particular time. 

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. 

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 Gold pays or is deemed to pay a dividend on the holder’s Common Shares 
will  be  subject  to  Canadian  withholding  tax,  and  Vista  Gold  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, but should generally be reduced under the Convention to 15% 
(or, if the U.S. Resident Holder owns at least 10% of the voting stock of Vista Gold, 5%) 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 

37 

 
 
 
 
 
 
 
 
 
 
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 "passive foreign 
investment company" (commonly known as 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  “passive  foreign  investment 
company”, 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 2015, 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 
three  years  ended  December 31,  2015,  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.

Overview 

Vista  Gold  Corp.  and  its  subsidiaries  (collectively,  “Vista,”  the  “Company,”  “we,”  “our,”  or  “us”)  are  engaged  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.  

The Company’s flagship asset is its 100% owned Mt Todd gold project (“Mt Todd”). Completion of a feasibility study 
or  the  development  of  the  project  is  not  justified  at  this  time  due  to  the  current  low  gold  price.  However,  with  the 
completion of the environmental impact statement in 2014 and the previous completion of a significant amount of the 
project engineering and design, much of which is contained in the previously released preliminary feasibility study, we 
believe  that  the  permitting  risk  is  substantially  reduced  and  the  potential  development  timeline  at  Mt  Todd  is  well 
defined.  We  believe  we  are  now  well  positioned,  subject  to  sustained  improvement  in  gold  prices,  to  move  forward 
quickly with the completion of the Mt Todd feasibility study. At the time the May 2013 PFS was completed, because of 
the high proportion of work that was already completed to feasibility study standards, it was estimated that the feasibility 
study could be completed within six months of its start at a cost of approximately $2,500.  

Outlook 

We do not currently generate cash  flows from  mining operations. The prices for gold equities, particularly those  with 
early stage projects, have decreased significantly during the past few years, and capital raising on reasonable terms has 

38 

 
 
  
 
 
 
 
 
 
 
 
 
 
become more difficult for mining companies which do not have producing assets.  These market conditions are expected 
to  continue  for  the  foreseeable  future,  and  could  affect  our  ability  to  raise  sufficient  capital  to  advance  Mt  Todd  on 
reasonable terms, if at all.   

Since 2013 we have financed our business without share dilution and we have significantly reduced our costs to mitigate 
the effects of these difficult markets. We believe  we have sufficient cash to fund our currently planned programs into 
2018, while retaining opportunities to access additional financing from non-dilutive sources.  Potential future sources of 
non-dilutive financing include the sale of our used mill equipment (which we have recently cleaned and repainted), other 
non-core  assets  including  Guadalupe  de  los  Reyes  (defined  in  “Item  2:  Properties”  above),  and,  depending  on  market 
conditions, our remaining common shares of Midas Gold Corp. (“Midas Gold Shares”).  Future R&D grants from the 
Government of Australia, if any, are expected to be significantly smaller than those received in 2015. 

As a result of cost cutting measures introduced during 2013 and 2014 and continued to date, and a favorable Australian 
dollar exchange rate, the Company’s 2016 fixed costs, those cash expenditures necessary to ensure that we preserve our 
property rights and meet all of our safety, regulatory and environmental responsibilities, are expected to average $1,400 
to $1,600 per quarter, with seasonal fluctuations. Subject to availability of funding, we will continue to consider selected 
discretionary programs, mainly consisting of technical studies and exploration programs, that could be expected to add 
value  to  Mt  Todd  and  better  position  us  to  quickly  advance  the  project  to  development  when  economic  conditions 
warrant.    In  addition,  with  our  improved  treasury  and  strong  management  team  we  are  in  a  position  to  judiciously 
evaluate and pursue other near-term value creating opportunities. 

Results from Operations 

Summary 

As a result of our commitment to non-dilutive financing, together with our strict cost management policies, the Company 
continues to be well funded and able to execute selected strategic discretionary programs. 

Consolidated net income for the year ended December 31, 2015 was $1,011 or $0.01 per basic share. Consolidated net 
loss for the year ended December 31, 2014 was $18,926 or $0.23 per basic share.  The principal components of our 2015 
net income and these year-over-year changes are discussed below. 

Exploration, property evaluation and holding costs 

Exploration,  property  evaluation  and  holding  costs,  including  fixed  cash  costs,  cash  discretionary  programs,  and  non-
cash  stock-based  compensation,  were  $4,265  and  $3,991  during  the  years  ended  December  31,  2015,  and  2014, 
respectively.    These  costs  are  predominantly  associated  with  Mt  Todd.  2015  fixed  costs,  those  cash  expenditures 
necessary  to  ensure  that  we  preserve  our  property  rights  and  meet  all  of  our  safety,  regulatory  and  environmental 
responsibilities,  were  substantially  unchanged  from  2014,  consistent  with  our  expectations.  Unlike  2014  however,  in 
2015  we  completed  discretionary  proof-of-concept  drilling  programs  on  the  exploration  licenses  and  on  the  mineral 
licenses at a total cost of A$888 ($653).   

Included in the 2015 and 2014 costs is non-cash stock-based compensation of $244 and $251, respectively.  

The weaker Australian dollar in 2015 compared to 2014 resulted in a U.S. dollar cost reduction of approximately $642.    

Corporate administration  

Corporate  administration  costs,  including  fixed  cash  costs,  cash  discretionary  programs,  and  non-cash  stock-based 
compensation, were $3,888 and $3,798 for the years ended December 31, 2015, and 2014 respectively.  Discretionary 
programs totaling $520 are included in the 2015 costs; there were no similar programs in 2014. The 2014 cost included 
$148 of severance costs resulting from the 2013 staff reductions; there were no severance costs in 2015.   

Included in the 2015 and 2014 costs is non-cash stock-based compensation of $573 and $875, respectively.

Gain on disposal of mineral property 

In  October  2013,  we  sold  our  100%  debt  and  equity  participation  in  the  Los  Cardones  gold  project  located  in  Baja 
California  Sur,  Mexico  (“Los  Cardones  Sale”)  to  Invecture  Group,  S.A.  de  C.V.  (“Invecture”)  and  RPG  Structrued 
Finance  S.a.R.L.  (together,  the  “Purchasers”)  for  a  total  of  $13,000  ($7,000  of  which  was  paid  in  October  2013  and 
$6,000 was originally payable January 2014 (the “Subsequent Payment”) subject to the Purchasers’ option to elect to not 
make the Subsequent Payment).  In 2014, the due date for the Subsequent Payment was extended to January 30, 2015 for 
additional consideration of $500 payable. In October 2014, Invecture announced that the Los Cardones gold project, had 
been suspended because the conditions for its development were not favorable at that time, which introduced substantial 
doubt that the Subsequent Payment would be made. After making this announcement, there were no apparent significant 
favorable  changes  to  incentivize  Invecture  to  lift  the  suspension.  In  January  2015,  we  agreed  to  amend  the  payment 
terms (the “Amendment”) of the Los Cardones Sale. Under the Amendment, the Company received a payment of $2,994 
net of legal costs from the Purchasers as full and final payment for 100% of the Company’s interest in the project, which 
resulted in a realized gain of $1,958.  

Write-down value-added tax receivable 

For the year ended December 31, 2015, we incurred a non-cash write-down associated with value-added tax (“VAT”) 
receivable  in  Mexico  of  $572.  The  Mexican  tax  authorities  have  denied  our  claim  for  the  VAT  recovery;  we  are 
contesting their position.  No similar write-down occurred during the year ended December 31, 2014.  

Write-down of Amayapampa interest 

In December 2014, the owner of the Amayapampa gold project completed the sale of 100% of the project to a private 
investor. Accordingly, at that time, we evaluated the carrying value of our interest in Amayapampa. Given the frequency 
of ownership changes over the past several years, the conditions in the gold market, and the political climate in Bolivia, 
we  concluded  that  there  is  no  more  than  a  remote  possibility  that  the  Amayapampa  project  would  be  successfully 
developed and operated within the foreseeable future; and an impairment amount equal to the $4,813 carrying value was 
included  in  our  Consolidated  Statements  of  Income/(Loss)  and  Comprehensive  Income/(Loss)  for  the  year  ended 
December 31, 2014. There were no similar charges for the year ended December 31, 2015.  

Write-down of mineral properties 

During 2014, we completed a review of the permitting process and probable impediments to developing the Long Valley 
gold project, and concluded that the permitting process  would consume an inordinate amount of our limited resources 
and time. Accordingly, we will not attempt to advance this project in the foreseeable future.  As a result, an impairment 
amount  equal  to  the  $750  carrying  value  was  taken  for  the  year  ended  December  31,  2014.  There  were  no  similar 
charges for the year ended December 31, 2015.  

Non-operating income and expenses   

Loss on Other Investments 

Loss on other investments was $1,593 and $4,112 for the years ended December 31, 2015 and 2014, respectively.  These 
amounts are the result of changes in fair value of our Midas Gold Shares.  The 2015 loss includes a realized loss of $348 
on the sale of 8,000,000 Midas Gold Shares; the 2014 loss is net of a realized gain of $155 on the sale of 16,000,000 
Midas Gold Shares.   

Research and development grant 

During  the  year  ended  December  31,  2015,  the  Company  received  Research  &  Development  (“R&D”)  Tax  Incentive 
payments totaling A$13,470 ($10,220), net of costs to prepare and file. These amounts were paid under the Australian 

40 

 
 
 
 
 
 
 
 
 
 
 
 
 
Government’s R&D Tax Incentive Program, a program designed to encourage industry to engage in R&D activities that 
benefit Australia; and relate to costs we incurred during the 2012 and 2013 fiscal years for qualifying R&D programs.  

This R&D Tax Incentive program is a self-assessment process, and as such, the Australian Government has the right to 
review the qualifying programs and expenditures for a period of four years.        

There were no similar grants for the year ended December 31, 2014.   

Financial Position, Liquidity and Capital Resources 

Operating Activities 

Net cash provided by/(used in) operating activities was $3,009 and $(7,058) for the years ended December 31, 2015, and 
2014, respectively.  Cash provided in 2015 includes  grants totaling $10,220, net of costs to prepare and  file, from the 
Government of Australia related to research and development expenditures we incurred in 2012 and 2013.  Other factors 
that contributed to the positive year-over-year change are discussed in “Results from Operations” above.   

Investing Activities 

The Company continues to monetize non-core assets as a non-dilutive means of financing. Cash provided by investing 
activities for the for the year ended December 31, 2015 was comprised of proceeds received from the Los Cardones Sale 
(defined  in  “Item  2:  Properties”  above)  of  $2,994  net  of  legal  costs,  the  Guadalupe  de  los  Reyes  Option  Agreement 
(defined in “Item 2: Properties” above) of $496 net of legal costs, and the sale of 8,000,000 Midas Gold Shares for net 
proceeds of $2,772.  $11,990 was used to purchase U.S. and Australian Government Treasury bills, net of redemptions.   

 Net cash provided by investing activities of $11,641 for the year ended December 31, 2014 was primarily due to the sale 
of 16,000,000 Midas Gold Shares for net proceeds of $10,560 and $1,028 received from the Los Cardones sale and the 
Guadalupe de los Reyes Option Agreement.   

Financing Activities 

There were no cash transactions from financing activities during year ended December 31, 2015. 

Net cash used in financing activities was $6,344 for the year ended December 31, 2014 was a result of the repayment of 
the loan facility entered into in 2013.  

Liquidity and Capital Resources 

Cash flows  generated during the  year ended December 31, 2015 included the receipt of $2,772 net proceeds from the 
sale of 8,000,000 Midas Gold Shares; the receipt of $2,994 net of legal costs as the final payment for the Los Cardones 
gold  project;  the  receipt  of  a  scheduled  $496  option  payment  net  of  legal  costs  for  the  Guadalupe  de  los  Reyes 
gold/silver  project;  and  receipt  of  grants  totaling  $10,220,  net  of  costs  to  prepare  and  file,  from  the  Government  of 
Australia related to  Research  & Development (“R&D”) Tax Incentive  for qualifying R&D expenditures  we incurred in 
2012 and 2013.  As a result of these transactions, our cash and short term investments (comprised of U.S. and Australian 
Government Treasury Bills) as of December 31, 2015  increased to $12,892, from $3,714 as at December 31, 2014; and 
our working capital increased to $14,399 compared with working capital of $10,535 at December 31, 2014.  

The  continuing  long-term  viability  of  the  Company  is  dependent  upon  our  ability  to  secure  sufficient  funding  and 
ultimately to generate future profits from operations. 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 fund exploration and development activities that could lead to profitable production or proceeds from the disposition 
of these assets.

Fair Value Accounting 

The following table sets forth the Company’s assets measured on a recurring basis 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 significant to the fair value measurement.

Our marketable securities and investment in Midas Gold 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 used mill equipment value is based on third party assessments of the projected sale value, net of commissions and 
other costs to sell, giving full consideration to current market conditions and an orderly sale process. 

At December 31, 2015, the assets classified within Level 3 of the fair value hierarchy represent 78% of the total assets 
measured  at  fair  value.  There  have  been  no  transfers  between  levels  in  2015  nor  have  there  been  any  changes  in 
valuation techniques. 

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 

During November 2015, we entered into a two-year lease agreement to store our used mill equipment.  Monthly rent for 
the term of the lease is C$18 ($13). 

Critical Accounting Policies and Recent Accounting Pronouncements 

Critical accounting policies 

Use of Estimates 

The  Company’s  Consolidated  Financial  Statements  have  been  prepared  in  accordance  with  generally  accepted 
accounting  principles  in  the  United  States  (“U.S.  GAAP”).  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  including  marketable 
securities;  useful  lives  of  assets  for  asset  depreciation  purposes;  valuation  allowances  for  deferred  tax  assets;  the  fair 
value and accounting treatment of stock-based compensation; and asset impairments (including impairments long-lived 
assets and investments). 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 differ from the amounts estimated 
in these financial statements.

Foreign Currency Transactions 

Our functional currency is the U.S. dollar. Gains and losses resulting from foreign currency transactions denominated in 
currency other than the functional currency are recorded at the approximate rate of exchange at the transaction date in 
other expense. For each of the years ended December 31, 2015 and 2014, 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  and  Australian  government  treasury  bills  and/or  notes.  Australian  dollar 
denominated  treasury  bills  may  result  in  currency  risk  associated  with  fluctuation  in  exchanges  rates.  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 
in accordance with U.S. GAAP and SEC Industry Guide 7 reserves are established, the costs then incurred 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 or impaired, 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 additional capital for these purposes.   

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). 

Assets held for sale 

Plant and equipment is classified as held for sale when the following conditions are met: (i) assets (or group of assets) 
are actively marketed for a price which reasonably approximates the fair value at the time of sale; (ii) management has 

43 

 
 
 
 
 
 
 
 
 
 
 
 
committed to a plan to sell the assets (or group of assets); (iii) the assets (or group of assets) are available  for sale in 
current condition; and (iv) sale is probable within the next 12 months. Assets held for sale are not depreciated.  

Stock-Based Compensation 

Under our stock option and long-term equity incentive plans, stock incentive options and restricted stock units may be 
granted  to  executives,  employees,  consultants  and  non-employee  directors.  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  the  options  are  calculated  using  the  Black-
Scholes option pricing model and forfeiture rates are based on historic trends and future projections, as appropriate. The 
fair value of restricted stock units is based on the closing price of our common shares on the grant date and forfeiture 
rates are based on historic trends and future projections, as appropriate. 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. 

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, 
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, is accounted for using the fair value option based 
on quoted market prices in an active market and is included in Level 1 of the fair value hierarchy.  

Research and Development (“R&D”) Grants 

The Company has received Research and Development Tax Incentive payments from the Australian Government.  The 
Company’s activities in Australia do not generate revenue subject to Australian income tax. Consequently, the R&D Tax 
Incentive payment is considered a government grant, as opposed to an income tax refund.  Grants are recognized when 
there is reasonable assurance that the grant will be received and that conditions attached to the grant have been met.  

Recent accounting pronouncements 

Financial  Instruments  –  Overall:  Recognition  and  Measurement  of  Financial  Assets  and  Financial  Liabilities 
(Accounting Standard Update 2016-01) 

44 

 
 
 
 
 
 
 
 
 
 
 
 
In January 2016, the FASB issued guidance related to accounting for equity investments, financial liabilities under the 
fair value option, presentation and disclosure requirements for financial instruments and the valuation allowance analysis 
regarding unrealized losses on available-for-sale debt securities.  The guidance with respect to equity investments only 
will  affect  the  Company.  Equity  investments,  not  accounted  for  utilizing  the  equity  method,  will  be  measured  at  fair 
value  with  changes  flowing  through  the  statement  of  income/loss  rather  than  through  accumulated  comprehensive 
income/loss on the balance sheet.  The classification of available-for-sale for equity securities is eliminated.  Finally, the 
impairment  analysis  for  these  equity  investments  will  be  a  one-step  approach  whereby  companies  are  required  to 
qualitatively assess for impairment at the end of each reporting period by estimating the fair value of the investment and 
recognizing in the current period an impairment loss equal to the difference between the fair value and the carrying value 
of  the  investment.    The  standard  is  effective  for  fiscal  years  beginning  after  December  15,  2017,  with  early  adoption 
permitted. We expect to early adopt this guidance in the first quarter of 2016 and do not anticipate that the adoption of 
this guidance will have a material impact on our financial statements. 

Balance Sheet Classification of Deferred Taxes (Accounting Standards Update 2015-17) 

In November 2015, the FASB issued guidance regarding the presentation of deferred taxes on the balance sheet.  The 
new  guidance  requires  that  all  deferred  tax  assets  and  liabilities,  including  any  corresponding  valuation  allowance,  be 
classified  as  noncurrent  on  the  balance  sheet.  The  requirement  for  jurisdiction-by-jurisdiction  analysis  remains 
unchanged.  The guidance is effective for fiscal years beginning after December 15, 2016, inclusive of interim periods, 
with  early  adoption  permitted,  and  may  be  applied  either  prospectively,  for  all  deferred  tax  assets  and  liabilities,  or 
retrospectively.  We  have  early  adopted  this  guidance,  retrospectively,  thus  adjusting  our  December  31,  2014  balance 
sheet  and  related  disclosures  as  if  the  guidance  had  been  implemented  at  that  time.  As  our  deferred  tax  assets  and 
liabilities offset, and are in the same jurisdiction, we do not present deferred tax assets and liabilities separately on our 
balance sheet.  

Presentation of Financial Statements - Going Concern (Subtopic 205-40) 

In  August  2014,  the  FASB  issued  guidance  related  to  financial  statement  presentation  regarding  disclosures  about  an 
entity’s  ability  to  continue  as  a  going  concern.    The  new  guidance  addresses  management’s  responsibility  to  evaluate 
whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related footnote 
disclosures. Management’s evaluation should be based on relevant conditions and events that are known and reasonably 
knowable at the date that the financial statements are issued. The standard is effective for the first interim period within 
annual  reporting  periods  ending  after  December  15,  2016,  with  early  adoption  permitted.  We  do  not  expect  to  early

Management’s Report on Internal Control Over Financial Reporting  

The management of Vista Gold Corp. (the “Company”) 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, 2015. 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,  2015,  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, 2015  has 
been audited by EKS&H LLLP, an independent registered public accounting firm, as stated in their report which appears 
herein.

Report of Independent Registered Public Accounting Firm 

Board of Directors and Shareholders 
Vista Gold Corp. 
Littleton, Colorado 

We have audited the accompanying consolidated balance sheets of Vista Gold Corp. and subsidiaries (the “Company”) 
as of December 31, 2015 and 2014, and the related consolidated statements of income (loss) and comprehensive income 
(loss),  shareholders’  equity,  and  cash  flows  for  the  years  then  ended.  We  have  also  audited  the  Company’s  internal 
control over financial reporting as of December 31, 2015, based on criteria established in Internal Control—Integrated 
Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission (“COSO”). 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 these financial statements and an opinion on the Company’s internal control over financial reporting based on 
our audits. 

We conducted our audits in accordance with the standards of the Public Company Accounting Oversight Board (United 
States). Those standards require that we plan and perform the audits to obtain reasonable assurance about  whether the 
financial statements are free of material misstatement and whether effective internal control over financial reporting was 
maintained in all material respects. Our audits of the financial statements included examining, on a test basis, evidence 
supporting  the  amounts  and  disclosures  in  the  financial  statements,  assessing  the  accounting  principles  used  and 
significant  estimates  made  by  management,  and  evaluating  the  overall  financial  statement  presentation.  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. 

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 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. 

In  our  opinion,  the  consolidated  financial  statements  referred  to  above  present  fairly,  in  all  material  respects,  the 
financial  position  of  Vista  Gold  Corp.  and  subsidiaries  as  of  December  31,  2015  and  2014,  and  the  results  of  their 
operations  and  their  cash  flows  for  each  of  the  years  then  ended  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,  2015,  based  on  criteria  established  in  Internal 
Control—Integrated  Framework  (2013)  issued  by  the  Committee  of  Sponsoring  Organizations  of  the  Treadway 
Commission (“COSO”).

1. Nature of Operations 

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. 

Our principal asset is our flagship Mt Todd gold project (“Mt Todd”) in Northern Territory (“NT”), Australia. We also 
hold 4.9% of the outstanding common shares of Midas Gold Corp. (“Midas Gold Shares”), non-core projects in Mexico 
and the United States and a royalty interest in a project in Indonesia. 

2. Significant Accounting Policies 

Principles of Consolidation 

The Consolidated Financial Statements include the accounts of Vista Gold Corp. and more-than-50%-owned subsidiaries 
that  it  controls  and  entities  over  which  control  is  achieved  through  means  other  than  voting  rights.  All  significant 
intercompany  balances  and  transactions  have  been  eliminated.  The  Consolidated  Financial  Statements  have  been 
prepared in accordance with generally accepted accounting principles in the United States (“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 including marketable securities; useful lives of assets for asset depreciation purposes; 
valuation allowances for deferred tax assets; the fair value and accounting treatment of stock-based compensation; and 
asset  impairments  (including  impairments  long-lived  assets  and  investments).  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 differ from the amounts estimated in these financial statements.  

Foreign Currency Transactions 

Our functional currency is the U.S. dollar.  Gains and losses resulting from foreign currency transactions denominated in 
currency other than the functional currency are recorded at the approximate rate of exchange at the transaction date in 
other expense. For each of the years ended December 31, 2015 and 2014, we recorded insignificant net foreign currency 
gains/(losses).  

Short-term Investment 

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  and  Australian  government  treasury  bills  and/or  notes.  Australian  dollar 
denominated  treasury  bills  may  result  in  currency  risk  associated  with  fluctuation  in  exchanges  rates.  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 
in accordance with U.S. GAAP and SEC Industry Guide 7 reserves are established, the costs then incurred to develop 
such  property  will  be  capitalized.    Capitalized  costs  will  be  depleted  using  the  units-of-production  method  over  the 

53 

 
 
 
 
 
 
 
 
 
 
 
 
 
estimated life of the proven and probable reserves.  If mineral properties are subsequently abandoned or impaired, 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 additional capital for these purposes.    

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). 

Assets held for sale 

Plant and equipment is classified as held for sale when the following conditions are met: (i) assets (or group of assets) 
are actively marketed for a price reasonable to the fair value at the time of sale; (ii) management has committed to a plan 
to sell the assets (or group of assets); (iii) the assets (or group of assets) are available for sale in current condition; and 
(iv) sale is probable within the next 12 months. Assets held for sale are not depreciated.  

Stock-Based Compensation 

Under our stock option and long-term equity incentive plans, stock incentive options and restricted stock units may be 
granted  to  executives,  employees,  consultants  and  non-employee  directors.  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  the  options  are  calculated  using  the  Black-
Scholes option pricing model and forfeiture rates are based on historic trends and future projections, as appropriate. The 
fair value of restricted stock units is based on the closing price of our common shares on the grant date and forfeiture 
rates are based on historic trends and future projections, as appropriate. 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.   

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: 

54 

 
 
 
 
 
 
 
 
 
 
•  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, 
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, is accounted for using the fair value option based 
on quoted market prices in an active market and is included in Level 1 of the fair value hierarchy.  

Research and Development (“R&D”) Grants 

The  Company  has  received  Research  and  Development  Tax  Incentive  payments  from  the  Australian  Government. 
Accounting practice generally refers to International Accounting Standard 20 “Accounting for Government Grants and 
Disclosure  of  Government  Assistance”  (“IAS  20”)  to  determine  the  most  appropriate  accounting  for  payments  of  this 
type.  The Company’s activities in  Australia do not generate revenue subject to Australian income tax. Consequently, 
under IAS 20, the R&D Tax Incentive payment is considered a government grant, as opposed to an income tax refund.  
Grants are recognized when there is reasonable assurance that the grant will be received and that conditions attached to 
the grant have been met. 

Recent accounting pronouncements   

Financial  Instruments  –  Overall:  Recognition  and  Measurement  of  Financial  Assets  and  Financial  Liabilities 
(Accounting Standard Update 2016-01) 

In January 2016, the FASB issued guidance related to accounting for equity investments, financial liabilities under the 
fair value option, presentation and disclosure requirements for financial instruments and the valuation allowance analysis 
regarding unrealized losses on available-for-sale debt securities.  The guidance with respect to equity investments only 
will  affect  the  Company.  Equity  investments,  not  accounted  for  utilizing  the  equity  method,  will  be  measured  at  fair 
value  with  changes  flowing  through  the  statement  of  income/loss  rather  than  through  accumulated  comprehensive 
income/loss on the balance sheet.  The classification of available-for-sale for equity securities is eliminated.  Finally, the 
impairment  analysis  for  these  equity  investments  will  be  a  one-step  approach  whereby  companies  are  required  to 
qualitatively assess for impairment at the end of each reporting period by estimating the fair value of the investment and 
recognizing in the current period an impairment loss equal to the difference between the fair value and the carrying value 
of  the  investment.    The  standard  is  effective  for  fiscal  years  beginning  after  December  15,  2017,  with  early  adoption 
permitted. We expect to early adopt this guidance in the first quarter of 2016 and do not anticipate that the adoption of 
this guidance will have a material impact on our financial statements. 

Balance Sheet Classification of Deferred Taxes (Accounting Standards Update 2015-17) 

In November 2015, the FASB issued guidance regarding the presentation of deferred taxes on the balance sheet.  The 
new  guidance  requires  that  all  deferred  tax  assets  and  liabilities,  including  any  corresponding  valuation  allowance,  be 
classified  as  noncurrent  on  the  balance  sheet.  The  requirement  for  jurisdiction-by-jurisdiction  analysis  remains 
unchanged.  The guidance is effective for fiscal years beginning after December 15, 2016, inclusive of interim periods, 

55 

 
 
 
 
 
 
 
 
 
 
 
with  early  adoption  permitted,  and  may  be  applied  either  prospectively,  for  all  deferred  tax  assets  and  liabilities,  or 
retrospectively.  We  have  early  adopted  this  guidance,  retrospectively,  thus  adjusting  our  December  31,  2014  balance 
sheet  and  related  disclosures  as  if  the  guidance  had  been  implemented  at  that  time.  As  our  deferred  tax  assets  and 
liabilities offset, and are in the same jurisdiction, we do not present deferred tax assets and liabilities separately on our 
balance sheet.  

Presentation of Financial Statements - Going Concern (Subtopic 205-40) 

In  August  2014,  the  FASB  issued  guidance  related  to  financial  statement  presentation  regarding  disclosures  about  an 
entity’s  ability  to  continue  as  a  going  concern.    The  new  guidance  addresses  management’s  responsibility  to  evaluate 
whether there is substantial doubt about an entity’s ability to continue as a going concern and to provide related footnote 
disclosures. Management’s evaluation should be based on relevant conditions and events that are known and reasonably 
knowable at the date that the financial statements are issued. The standard is effective for the first interim period within 
annual  reporting  periods  ending  after  December  15,  2016,  with  early  adoption  permitted.  We  do  not  expect  to  early 
adopt this guidance and do not believe that the adoption of this guidance will have a material impact on our financial 
statements.  

3. Other Investments 

Midas Gold Corp. Combination 

During February 2014, we sold 16,000,000 Midas Gold Shares at a price of C$0.80 ($0.73) per Midas Gold Share for net 
proceeds  of  $10,560  reducing  the  total  of  our  Midas  Gold  Shares  to  15,802,615  or  approximately  11.2%    of  the 
outstanding Midas Gold Shares outstanding, on a non-dilutive basis, at that time.  This sale resulted in a realized gain on 
other investments of  $155  based on the realized  value at the time of the sale compared to the fair value of the Midas 
Gold Shares at December 31, 2013, net of costs to sell.  

During March 2015, we sold 8,000,000 Midas Gold Shares, at a price of C$0.46 ($0.36) per Midas Gold Share, for net 
proceeds  of  $2,772,  reducing  the  total  Midas  Gold  Shares  we  own  to  7,802,615  or  approximately  4.9%  of  the  Midas 
Gold Shares outstanding, on a non-dilutive basis. This sale resulted in a realized loss on other investments of $348 based 
on the realized value at the time of the sale compared to the fair value of the Midas Gold Shares at December 31, 2014, 
net of costs to sell.  

Upon initial recognition of its investment in the Midas Gold Shares, Vista elected to apply the fair value option, and as 
such, the investment is 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.   

The following table summarizes our investment in Midas Gold Shares as at December 31, 2015 and 2014.

During  April  2014,  Minera  Gold  Stake  S.A.  de  C.V.  (“MGS”),  Vista’s  wholly-owned  subsidiary,  entered  into  a 
definitive option agreement (the “Option Agreement”) to option a 70% interest in the Guadalupe de los Reyes gold/silver 
project  in  Sinaloa,  Mexico  to  Great  Panther  Silver  Limited  (formerly  Cangold  Limited)  (“Great  Panther”)  for 
consideration of  $5,000 in five payments over a three-year period, with payments totaling $1,000 in the first year ($500 
received in 2014 and $496 net of legal costs was received in March 2015), $1,500 due in February 2016 (postponed from 
January  2016)  and  $2,500  due  in  January  2017.  The  Option  Agreement  provided  that  all  cash  payments  are  non-
refundable and optional to Great Panther, and in the event Great Panther failed to pay any of the required amounts on the 
scheduled dates or failed to comply with its other obligations, the Option Agreement would terminate and Great Panther 
would have no interest in the Guadalupe de los Reyes gold/silver project. 

On February 25, 2016 Vista received notification from Great Panther that it is terminating the Option Agreement and the 
$1,500  option  payment  due  in  February  2016  was  not  made.    Pursuant  to  the  terms  of  the  Option  Agreement,  Vista 
retains all amounts already paid by Great Panther and 100% of the Guadalupe de los Reyes gold/silver project.  

Although  the  termination  of  the  Option  Agreement  indicates  the  potential  for  impairment  of  the  carrying  value  of 
Guadalupe  de  los  Reyes  mineral  property,  our  review  has  concluded  that  the  $1,728  carrying  value  should  not  be 
impaired considering the quantity of mineral resources contained in the concessions, and the strategic value that these 
resources represent.   

Los Cardones 

In  October  2013,  we  sold  our  100%  debt  and  equity  participation  in  the  Los  Cardones  gold  project  located  in  Baja 
California Sur, Mexico (“Los Cardones Sale”) to Invecture and RPG Structrued Finance S.a.R.L. (the “Purchasers”) for 
a  total  of  $13,000  ($7,000  of  which  was  paid  in  October  2013  and  $6,000  was  originally  payable  January  2014  (the 
“Subsequent Payment”) subject to the Purchasers’ option to elect to not make the Subsequent Payment).  In 2014, the 
due date for the Subsequent Payment was extended to January 30, 2015 for additional consideration of $500. In October 
2014,  Invecture  announced  that  the  Los  Cardones  gold  project,  had  been  suspended  because  the  conditions  for  its 
development were not favorable at that time, which introduced substantial doubt that the Subsequent Payment would be 
made.  After making this announcement, there were no apparent significant favorable changes to incentivize Invecture to 
lift the suspension. In January 2015, we agreed to amend the payment terms (the “Amendment”) of the Los Cardones 
Sale. Under the Amendment, the Company received a payment of $2,994 net of legal costs from the Purchasers as final 
payment for 100% of the Company’s interest in the project. This resulted in a realized gain of approximately $1,958. 

Long Valley 

We acquired the Long Valley gold project in 2003.  During 2014, we completed a review of the permitting process and 
probable impediments to developing the project, and concluded that the permitting process would consume an inordinate 
amount of our limited resources and time.  Accordingly,  we  will  not attempt to advance this project in the foreseeable 
future.  As  a  result,  an  impairment  amount  equal  to  the  $750  carrying  value  has  been  included  in  our  Consolidated 
Statements of Income/(Loss) and Comprehensive Income/(Loss) for the year ended December 31, 2014.

projected sale value, net of commissions and other costs to sell, giving full consideration to current market conditions 
and an orderly sale process. Although we continue to actively market this equipment, we no longer classify it as ‘held for 
sale’  on  our  balance  sheet  as  of  December  31,  2015  or  2014  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

Under our Stock Option Plan (the “Plan”) and our Long-Term Equity Incentive Plan (the “LTIP”), we may grant options 
and/or RSUs or restricted stock awards to our directors, officers, employees and consultants.  The combined maximum 
number  of  our  Common  Shares  that  may  be  reserved  for  issuance  under  the  Plan  and  the  LTIP  is  a  variable  number 
equal to 10% of the issued and outstanding Common Shares on a non-diluted basis. Options and RSUs under the Plan 
and LTIP, respectively, are granted from time to time at the discretion of the Board, with vesting periods and other terms

The fair value of stock options granted during the year ended December 31, 2014 (no stock options were granted for the 
year ended December 31, 2015) to employees, directors and consultants was estimated at the grant date using the Black-

8. 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, 
the  future  expenditures  that  may  be  required  for  compliance  with  these  laws  and  regulations  cannot  be  predicted. We 
conduct  our  operations  to  minimize  effects  on  the  environment  and  believe  our  operations  are  in  compliance  with 
applicable laws and regulations in all material respects. During May 2015, we settled a contract dispute for $295.  

Under our agreement with the Jawoyn Association Aboriginal Corporation (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 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  royalty  on  other  metals,  subject  to  a 
minimum payment of A$50 per year. 

During November 2015, we entered into a two-year lease agreement to store our used mill equipment.  Monthly rent for 
the term of the lease is C$18 ($13). 

9. Amayapampa Interest 

In December 2014, the owner of the Amayapampa gold project completed the sale of 100% of the project to a private 
investor. Accordingly, we evaluated the carrying value of our interest in Amayapampa, comprised of a right to receive 
an NSR royalty on future gold production, if any, plus certain additional cash payments if the project successfully starts 
commercial production. Given the  frequency of ownership changes over the past  several  years, the conditions in gold 
market,  and  the  political  climate  in  Bolivia,  we  concluded  that  there  is  no  more  than  a  remote  possibility  that  the 
Amayapampa project will be successfully developed and operated within the foreseeable future and that the asset was 
fully impaired, an impairment amount equal to the $4,813 carrying value was included in our Consolidated Statements of 
Income/(Loss) and Comprehensive Income/(Loss) for the year ended December 31, 2014.  

10.  Research and Development Grant 

During  the  year  ended  December  31,  2015,  the  Company  received  Research  &  Development  (“R&D”)  Tax  Incentive 
payments totaling $10,220, net of costs to prepare and file. These amounts were paid under the Australian Government’s

Australia; and relate to costs we incurred during the 2012 and 2013 fiscal years for qualifying R&D programs.  

This R&D Tax Incentive program is a self-assessment process, and as such, the Australian Government has the right to 
review the qualifying programs and expenditures for a period of four years.  No similar transactions occurred in 2014.  

11.  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 
significant to the fair value measurement.

Our marketable securities and investment in Midas Gold 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 used mill equipment value is based on third party assessments of the projected sale value, net of commissions and 
other costs to sell, giving full consideration to current market conditions and an orderly sale process. 

At December 31, 2015, the assets classified within Level 3 of the fair value hierarchy represent 78% of the total assets 
measured at fair value. There were no transfers between levels nor were there any changes in valuation methods in 2015.  

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

As of December 31, 2015 and 2014, all of our cash was held in liquid bank deposits and/or government treasury bills in 
the Unites States and Australia. 

There were no significant non-cash transactions for the year ended December 31, 2015 or 2014.  

During the year ended December 31, 2014, we paid interest associated with the 2013 Facility of $78.

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 $50,816, and $54,397 at December 
31,  2015  and  2014,  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.   

Loss Carryforwards 

The  Company  has  available  income  tax  losses  of  $63,684,  which  may  be  carried  forward  and  applied  against  future 
taxable income when earned. 

The losses expire as follows:

Of the total Canadian net operating loss, $20,033 relates to an equity component for share-issuance cost deduction for 
which no tax benefit for financial reporting purposes in the income statement will be recognized. 

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, 2015, 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 Authority for years ended on or before December 31, 
2012 or U.S. federal income tax examinations by the Internal Revenue Service for years ended on or before December 
31,  2012.    Some  U.S.  state  and  other  foreign  jurisdictions  are  still  subject  for  tax  examination  for  years  ended  on  or 
before December 31, 2011. 

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

14. 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  focused  principally  in  Australia  and  North 
America.  We  reported  no  revenues  during  the  years  ended  December  31,  2015  and  2014.  Geographic  location  of 
mineral properties and plant and equipment is provided in Notes 4 and 5, respectively.  

15. Subsequent Events  

Guadalupe de los Reyes Payment 

On February 25, 2016 Vista received notification from Great Panther Silver that it is terminating the Option Agreement 
and the $1,500 option payment due in February 2016 was not made.  See Note 4.

ITEM 9.  CHANGES IN AND DISAGREEMENTS WITH ACCOUNTANTS ON ACCOUNTING AND 
FINANCIAL DISCLOSURE. 

Effective  on  June  20,  2014,  the  Company,  upon  recommendation  from  its  audit  committee,  changed  auditors  from 
PricewaterhouseCoopers  LLP,  Denver,  Colorado  (“PwC”)  to  EKS&H  LLLP,  Denver,  Colorado  (“EKS&H”).    After 
completing a competitive process, the Company made the change as a result of ongoing efforts to reduce operating costs. 
On June 20, 2014 at the Company’s request and  upon  mutual agreement, PwC resigned as the independent registered 
public accounting  firm of  the Company.  The request  for resignation of PwC  was recommended and approved by the 
Company’s audit committee. 

PwC’s reports on the Company’s consolidated financial statements for each of the fiscal years ended December 31, 2013 
and  2012  did  not  contain  any  adverse  opinion  or  disclaimer  of  opinions  and  were  not  qualified  or  modified  as  to 
uncertainty, audit scope or accounting principles. 

During  the  two  fiscal  years  ended  December  31,  2013  and  2012  and  the  subsequent  interim  period  through  June  20, 
2014,  there  were  no  disagreements  with  PwC  on  any  matter  of  accounting  principles  or  practices,  financial  statement 
disclosure, or auditing scope or procedure, which disagreement(s), if not resolved to the satisfaction of PwC, would have 
caused it to make references to the subject matter of the disagreement(s) in connection with its reports on the Company’s 
consolidated financial statements for such years. 

No  reportable  events  (as  defined  in  Item  304(a)(1)(v)  of  Regulation  S-K)  occurred  during  the  two  fiscal  years  ended 
December 31, 2013 and 2012 and the subsequent interim period through June 20, 2014. 

PwC was provided the related disclosure on Form 8-K, and was provided a letter dated June 23, 2014 commenting on 
the disclosure, pursuant to Item 304(a)(3) of Regulation S-K, which was attached as Exhibit 16.1 to the Form 8-K (and 
was filed in Canada on SEDAR on June 23, 2014). 

Effective  June  20,  2014  the  Company,  upon  the  recommendation  of  its  audit  committee,  engaged  EKS&H  as  its 
principal independent registered public accountant. 

During  the  Company’s  two  fiscal  years  ended  December  31,  2013  and  2012  and  through  June  20,  2014,  neither  the 
Company nor anyone on its behalf consulted with EKS&H regarding either (i) the application of accounting principles to 
a  specific  transaction,  either  completed  or  proposed,  or  the  type  of  audit  opinion  that  might  be  rendered  on  the 
Company’s consolidated financial statements, nor did EKS&H provide either a written report or oral advice that EKS&H 
concluded  was  as  important  factor  considered  by  the  Company  in  reaching  a  decision  as  to  accounting  auditing  or 
financial  reporting  issues,  or  (ii)  any  matter  that  was  either  the  subject  of  a  disagreement  within  the  meaning  of  Item 
304(a)(1)(iv)  and  the  related  instruction  of  Regulation  S-K,  or  a  reportable  event  within  the  meaning  of  Item 
304(a)(1)(v) of Regulation S-K. 

ITEM 9A.  CONTROLS AND PROCEDURES. 

Disclosure Controls and Procedures. 

At the end of the period covered by this annual report on Form 10-K for the fiscal year ended December 31, 2015, an 
evaluation was carried out under the supervision of and with the participation of our management, including the Chief 
Executive Officer (“CEO”) and Chief Financial Officer (“CFO”), of the effectiveness of the design and operations of our 
disclosure controls and procedures (as defined in Rule 13a-15(e) and Rule 15d-15(e) under the Exchange Act). Based on 
that evaluation, the CEO and the CFO have concluded that as of the end of the period covered by this annual report, our 
disclosure  controls  and  procedures  were  effective  in  ensuring  that:  (i) information  required  to  be  disclosed  by  us  in 
reports  that  we  file  or  submit  to  the  SEC  under  the  Exchange  Act  is  recorded,  processed,  summarized  and  reported 
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.
