CAUTIONARY  NOTE  TO  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  metal  price  is  used  in  any  reserve  or  cash  flow  analysis  to  designate  reserves,  and  the  primary 
environmental analysis or report must be filed with the appropriate governmental authority. 

In  addition,  the  terms  “mineral  resource”,  “measured  mineral  resource”,  “indicated  mineral  resource”  and  “inferred 
mineral resource” are defined in and required to be disclosed by NI 43-101; however, these terms are not defined terms 
under SEC Industry Guide 7 and are normally not permitted to be used in reports and registration statements filed with 
the SEC. Investors are cautioned not to assume that all or any part of a mineral deposit in these categories will ever be 
converted into reserves. “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  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” 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.

valuable metals contained. 

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

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

“bismuthinite” means a mineral consisting of bismuth sulfide; it is an ore for bismuth.

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

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

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

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

“conglomerate” refers to clastic sedimentary rock that contains rounded particles that are greater than two millimeters in

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.

“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 quartz, feldspar and small rock fragments set in a compact, clay-fine matrix.  

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

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

“indicated mineral resource” and “indicated resource” means “indicated mineral resource” as defined by the CIM in the 
CIM Definition Standards and is that part of a mineral resource for which quantity, grade or quality, densities, shape and 
physical characteristics 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, 

3 

 
 
 
 
 
 
 
 
 
 
 
 
processing,  metallurgical,  infrastructure,  economic,  marketing,  legal,  environmental,  social,  governmental  or  other 
relevant factors. Such studies demonstrate that, at the time of reporting, extraction could reasonably be justified.  

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

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

“mineralized  material”  under  SEC Industry  Guide  7 is  a  mineralized  body  that  has  been  delineated  by  appropriately 
spaced  drilling  and/or  underground  sampling  to  support  a  sufficient  tonnage  and  average  grade  of  metal(s).  Such  a 
deposit does not qualify as a reserve until a comprehensive evaluation based upon unit cost, grade, recoveries, and other 
material factors conclude legal and economic feasibility. Mineralized material is 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 “PEA” 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 in the CIM Definition Standards 
is  a  comprehensive  study  of  a  range  of  options  for  the  technical  and  economic  viability  of  a  mineral  project  that  has 
advanced to a stage where a preferred mining method, in the case of underground mining, or the pit configuration, in the 
case of an open pit, is established and an effective method of mineral processing is determined. It includes a financial 
analysis  based  on  reasonable  assumptions  on  mining,  processing,  metallurgical,  economic,  marketing,  legal, 
environmental,  social  and  government  considerations  and  the  evaluation  of  any  other  relevant  factors  which  are 
sufficient for a qualified person, acting reasonably, to determine if all or part of the mineral resource may be converted 
to a mineral reserve at the time of reporting. A 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. 

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

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

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

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

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

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

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

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

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

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

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

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

“tpd” means tonnes per day.  

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

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

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

ITEM 1.  BUSINESS.  

Overview 

PART I 

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

The Company’s flagship asset is its 100% owned Mt Todd gold project (“Mt Todd”) in the Northern Territory (“NT”) 
Australia.  Mt  Todd  is  the  largest  undeveloped  gold  project  in  Australia.  In  January  2018,  the  Company  received 
authorization for the last major environmental permit and we announced the positive results of an updated preliminary 
feasibility study (the “PFS”) for Mt Todd. Subsequently, Vista has completed additional metallurgical testing, including 
ongoing  fine  grinding  evaluations,  which  demonstrate  further  improvements  in  gold  recovery.  With  these  important 
milestones  and  subsequent  project  improvements  complete,  Vista  is  in  a  better  position  to  identify  and  pursue  those 
strategic alternatives that may provide the best opportunity for shareholders to realize fair value for Mt Todd. We also 
hold 7.8 million of the outstanding common shares in the capital of Midas Gold Corp. (“Midas Gold Shares”), a non-
core project in Mexico and royalty interests in the United States and Indonesia. 

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

Corporate Organization Chart  

The name, place of incorporation, continuance or organization and percent of equity securities that we own or control as 
of February 6, 2019 for each of our subsidiaries is set out below.  

Employees 

As of December 31, 2018, we had 14 full-time and no part-time 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.  We evaluate, acquire, explore and advance gold exploration and potential development projects, 
which may lead to gold production or value adding strategic transactions.   We reported no operating revenues during the 
years  ended  December  31,  2018  and  2017.  Geographic  location  of  mineral  properties  and  plant  and  equipment  is 
provided in Notes 4 – Mineral Properties and 5 – Plant and Equipment to our Consolidated Financial Statements under 
the section heading “Item 8. Financial Statements and Supplementary Data” below. 

Reclamation 

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

The  Mt  Todd  site  was  not  reclaimed  when  the  mine  closed  in  the  late  1990’s.    Liability  for  the  reclamation  of  the 
environmental  conditions  existing  prior  to  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 does not expect to give such notice until a production 
decision  has  been  made,  the  project  is  fully  permitted  to  construct  the  mine,  and  the  necessary  financing  for  project 
construction has been arranged.   

11 

 
 
 
 
 
 
 
 
 
 
In 2016, the Province of British Columbia Ministry of Energy and Mines (“MEM”) requested that the Company prepare 
and  present  to  MEM  a  reclamation  plan  for  closure  and  abandonment  of  certain  mining  claims  in  British  Columbia 
which the Company had disposed of in 1996. Vista has presented a reclamation plan to MEM, however, execution of the 
reclamation plan has not started, as acceptance by MEM is pending. Assuming no other potentially responsible parties 
are identified and based on preliminary estimates of the reclamation and other related costs, we have accrued $242 as of 
December 31, 2018. 

Government Regulation 

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

Australia Laws  

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

Environmental Regulation 

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

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

During 2018, none of our project sites had any material non-compliance occurrences with any applicable environmental 
regulations.  See “Item 1. Business - Reclamation” above.

Competition 

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

Gold Price History 

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

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 
mining  and  comminution  processes  including  ore  sorting,  gold  production  rates,  revenue,  capital  and  operating  costs 
including  taxes  and  royalties  will  not vary unfavorably  from  the  estimates  and  assumptions  included in  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  equity  markets,  could 
impede 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 provide 30 days’ notice to the 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 and amount 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.   

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 
sufficient water resources may not be available leading to operations stopping until the water supply is replenished.   

14 

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

Our assets or our business activities may be subject to disputes that may result in litigation or other legal claims. We may 
be  subject  to  allegations  through  press,  social  media  or  other  mediums  that  may  or  may  not  be  founded.  We  may  be 
required  to  respond  to  or  defend  against  these  claims  and/or  allegations  which  will  divert  resources  away  from  our 
principal business. There can be no assurance that our defense of such claims and/or allegations would be successful, 
and  we  may  be  required  to  make  material  settlements.  This  could  have  a  material  adverse  effect  on  our  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  an  interest  in  certain  of  our  projects,  in  part  by  managing  the  respective  project.  Whether  or  not  we  hold  a 
majority  interest  in  a  respective  project,  our  Partner(s)  may:  (i)  have  economic  or  business  interests  or  goals  that  are 
inconsistent with or opposed to ours; (ii) exercise veto rights to block actions that we believe to be in the best interests of 
the project; (iii) take action contrary to our policies or objectives; or (iv) as a result of financial or other 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 Partners. 

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

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

We could be subject to environmental lawsuits. 

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

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

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

15 

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

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  an 
ability to execute a strategic transaction, or that the funds invested in them will ever be recovered. 

Financial and Business Risks 

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

The value of our assets, our ability to raise capital and our future economic returns are substantially dependent on the 
price of gold. The gold price fluctuates 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  or long positions on futures markets; 
the relative strength of the U.S. dollar; 
expectations of the future rate of inflation; 
interest rates; 
changes to economic 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  material  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  range  of  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 assets.  These conditions could result in the acquisition of a control position, or attempted acquisition of 
a control position in the Company at what we believe to be less than fair value. This could result in substantial costs to 
us  and  divert  our  management’s  attention  and  resources.  A  completed  acquisition  could  result  in  realized  losses  of 
shareholder value.  

16 

 
 
 
 
 
 
 
 
 
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.  

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

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

We  are  subject  to  changing  rules  and  regulations  promulgated  by  a  number  of  governmental  and  self-regulated 
organizations,  including  the  British  Columbia  Securities  Commission,  the  SEC,  the  Toronto  Stock  Exchange  (the 
“TSX”), the NYSE American, and the Financial Accounting Standards Board. These rules and regulations continue to 
evolve in scope and complexity and many new requirements have been created in response to laws enacted by the United 
States Congress, making compliance increasingly more difficult and uncertain, which could have an adverse effect on 
reputation and our stock price. 

We face intense competition in the mining industry. 

The mining industry is intensely competitive in all of its phases. Some of our competitors are much larger, established 
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.  If  we  are  unable  to  raise  sufficient  capital,  we  will  be  unable  to  execute  exploration  and 
development programs or such programs may be reduced in scope. Competition for equipment and supplies could result 
in shortage of necessary supplies and/or increased costs. Competition for outside services could result in increased costs, 
reduced  quality  of  service  and/or  delays  in  completing  services.  If  we  cannot  successfully  retain  or  attract  qualified 
employees,  our  ability  to  advance  the  development  of  Mt  Todd,  to  attract  necessary  financing,  to  meet  all  of  our 
environmental  and  regulatory  responsibilities,  or  to  take  opportunities  to  improve  our  business,  could  be  negatively 
affected.  This  could  have  a  material  adverse  effect  on  our  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 
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.   

17 

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

Broad  market  and  industry  factors  may  adversely  affect  the  price  of  our  common  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  market 
performance; 
stock market price and volume fluctuations of other publicly traded companies and, in particular, those that are 
in the mining industry; 
speculation about our business in the press or the investment community; 
conditions or trends in our industry or the economy generally; 
changes in the prices of gold; 
announcements by us or our competitors of significant acquisitions, strategic partnerships or divestitures; 
additions or departures of key personnel; and 
sales of our common 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, if any, against the U.S. dollar effectively increases our cost of doing business in 
Australia. This could have the effect of increasing the amount of capital required to continue to explore and develop Mt 
Todd, and/or reducing the pace at which it is developed.  

Our Australian R&D grants are subject to review.  

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

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

U.S. shareholders of our common shares should be aware that the Company believes it was classified as a PFIC during 
the taxable year ended December 31, 2018, 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 

18 

 
 
 
 
 
 
 
 
 
 
makes the mark-to-market election generally  must include as ordinary income each year the excess of the fair market 
value  of  the  Common  Shares  over  the  taxpayer’s  basis  therein.    This  paragraph  is  qualified  in  its  entirety  by  the 
discussion below in “Item 5. Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases 
of  Equity  Securities  -  “Certain  U.S.  Federal  Income  Tax  Considerations  for  U.S.  Residents.”  Each  U.S.  shareholder 
should consult his or her own tax advisor regarding the U.S. federal, U.S. state and local, and foreign tax consequences 
of the PFIC rules and the acquisition, ownership, and disposition of Common Shares.   

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 thresholds reflect the levels of confidence that exist at the time the study is 
completed.    Subsequent  changes  to  metal  prices,  foreign  exchange  rates  (if  applicable),  reclamation  requirements, 
operating and capital costs may cause actual results of economic viability to differ materially from these 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  increased  taxes  and  royalties  payable  to  governments  and 
communities.  

Mining exploration, development and operating activities are inherently hazardous.  

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

19 

 
 
 
 
 
 
 
 
 
 
 
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. 

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. 

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

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

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

 

 

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

“Inferred  mineral  resources”  –  We  advise  investors  that  although  this  term  is  recognized  by  Canadian 
regulations, the SEC does not recognize it. “Inferred mineral resources” have a great amount of uncertainty as 
to  their  existence,  and  great  uncertainty  as  to  their  economic,  technical  and  legal  feasibility.  It  cannot  be 
assumed that all or any part of an inferred mineral resource will ever be upgraded to a higher category. Under 

20 

 
 
 
 
 
 
 
 
 
 
 
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. Investors are 
cautioned not to assume that any part or all of an inferred mineral resource exists or is economically or legally 
minable. 

 

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

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

Units of measurement 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 

Current Technical Report 

The  PFS  for  Mt  Todd  pursuant  to  NI  43-101  was  filed  on  SEDAR  on  March  2,  2018  and  is  entitled  “NI  43-101 
Technical  Report  -  Mt  Todd  Gold  Project  -  50,000  tpd  Preliminary  Feasibility  Study  –  Northern  Territory,  Australia” 
with  an  effective  date  of  January  24,  2018  and  an  issue  date  of  March  2,  2018  prepared  by  Rex  Clair  Bryan,  Ph.D., 
Anthony Clark, P.E., Thomas L. Dyer, P.E., Amy L. Hudson, Ph.D., CPG, REM, Chris Johns, M.Sc., P.Eng., Benjamin 
S.  Johnson,  P.E.,  Deepak  Malhotra,  Ph.D.,  Zvon  Ponos,  BE,  MIEAust,  CPeng,  NER,  Guy  Roemer,  P.E.,  Vicki  J. 
Scharnhorst, P.E., LEED AP, D. Erik Spiller, QP, Jessica I. Spriet, P.E., Keith Thompson, CPG, PG, each of whom is a 
qualified person under NI 43-101.  

The following description of Mt Todd has been sourced, in part, from the PFS and readers should consult the PFS to 
obtain further particulars regarding Mt Todd.  The PFS is available for review under our profile at www.sedar.com. 

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

Pre-Feasibility Study Results: Base Case and Alternate Case 

The  PFS  evaluates  two  development  scenarios:  a  50,000  tpd  project  that  develops  more  of  the  Mt  Todd  resource  and 
generates a larger Net Present Value (“NPV”) (the “Base Case”); and a smaller and higher-grade 33,000 tpd project (the 
“Alternate Case”).  

The Base Case (50,000 tpd) includes: 

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

0.40 g-Au/t(1); 

  Average  annual  production  of  381,211  ounces  of  gold  over  the  mine  life,  including  average  annual 

production of 479,450 ounces of gold per year during the first five years of operations; 

  Life  of  Mine  (“LoM”)  average  cash  costs  of  $645  per  ounce,  including  average  cash  costs  of  $571  per 

ounce during the first five years of operations; 

  A 13 year operating life; 

  After-tax NPV5% of $679 million and internal rate of return (IRR) of 20.5% at $1,300 per ounce gold price 

and a USD:AUD exchange rate of 0.80, and 

21 

 
 
 
 
 
 
 
 
 
 
 
 

Initial capital requirements of $839 million. 

The Alternate Case (33,000 tpd) includes: 

  Estimated proven and probable reserves of 3.557 Moz of gold (128 Mt at 0.86 g-Au/t) at a cut-off grade of 

0.40 g-Au/t(1); 

  Average  annual  production  of  273,000  ounces  of  gold  over  the  mine  life,  including  average  annual 

production of 301,778 ounces of gold per year during the first five years of operations; 

  LoM average cash costs of $593 per ounce, including average cash costs of $581 per ounce during the first 

five years of operations; 

  An 11 year operating life; 

  After-tax  NPV5%  of  $418  million  and  IRR  of  17.8%  at  $1,300  per  ounce  gold  price  and  USD:AUD 

exchange rate of $0.80, and 

 

Initial capital requirements of $641 million.

plant will be sold as a going concern.    

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

The 50,000  tpd  Base  Case mine  plan  contains  207.7  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, 221.0 million tonnes of material containing 5.848 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  4.956  million 
ounces.  Average annual gold production over the life of mine is 381,211 ounces, averaging 479,450 ounces during the 
first  five  years  of  operations,  with  582,032  ounces  produced  in  the  first  year  of  operations.   Commercial  production 
would begin following approximately two years of construction and commissioning.

Alternative Case Presented in PFS 

The key differences between the Alternate Case and the Base Case include: 

 

 

a 33,000 tpd processing facility as compared to a 50,000 tpd facility with associated lower mining rates and 
a smaller mining fleet;  

pit design based on a pit shell calculated at $800/oz-Au  ($1,000/ozAu in the 50,000 tpd project); the same 
cut-off grade of 0.40 g-Au/t was used; and 

  A shorter operating life for the 33,000 tpd Alternate Case.

Property Description, Location and Access 

In 2006, through an agreement with the Deed Administrators for Pegasus Gold Australia Pty. Ltd. (“Pegasus”), the NT 
Government  and  the  Jawoyn  Association  Aboriginal  Corporation  (“JAAC”),  we  acquired  the  concession  rights  and 
access  to  Mt  Todd.  Also  in  2006,  through  an  agreement  with  the  NT  Government,  we  established  the  rights  and 
obligations of both parties with respect to Mt Todd site care and maintenance and potential future development. In 2017, 
the latter agreement was extended through the end of 2023.  

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

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

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 1.5 kilometers long, 
with several hanging wall structures providing additional width to the orebody.  Mineralization is open at depth as well 
as along strike, although the intensity of mineralization weakens to the north and south along strike. 

the  project  occurs 

The Mt Todd Base Case 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,  cone  crushers,  high  pressure  grinding  roll  (“HPGR”)  crushers,  followed  by  X-ray

transmission  (“XRT”)  and  laser  sorting,  and  primary  ball  mills,  followed  by  ISAMills,  as  discussed  in  greater  detail 
below.  Vista plans to recover gold in a conventional carbon-in-pulp (“CIP”) recovery circuit. 

The  Mt  Todd  site  was  not  reclaimed  when  the  mine  closed  in  the  late  1990s.    Liability  for  the  reclamation  of  the 
environmental  conditions  existing  prior  to  Vista’s  involvement  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 project 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 160,000 hectares. A map showing the location 
of the mineral licenses (“MLs”) and exploration licenses (“ELs”) and a table with a list of MLs and ELs and the holding 
requirements are set out below.  All of the estimated mineral resources are located within the boundaries of the MLs and 
substantially all of the estimated mineral resources at Mt Todd are located in the Batman deposit.  

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

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

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

We are required annually to submit an MMP that details work to be done on the property.  We have received approval 
for all work done on the project to date and obtained approval for the EIS.  Further permitting will be required before 
mine  development  can  start.  The  related  permitting  processes  are  relatively  straight-forward  and  are  not  expected  to 
impede to a material extent our exploration and future development plans.  Any future mining will require an approved 
closure plan and sufficient surety bonding to fund that closure.

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

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

History 

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

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

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

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

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

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

Billiton, who was the managing partner in an exploration program in the joint venture with Zapopan, discovered the Mt 
Todd mineralization, or more specifically the Batman deposit, in May 1988.  In 1992, Pegasus Gold Australia Pty. Ltd. 

30 

  
 
 
 
 
 
 
 
 
 
(“Pegasus”)  acquired  a  share  holding  in  Zapopan,  following  which  Zapopoan  acquired  Billiton’s  interest.  Pegasus 
progressively increased their shareholding until they acquired full ownership of Zapopan in July 1995. 

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

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

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

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

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

entered in to a contract with the Government of the Northern Territory of Australia 

Geological Setting, Mineralization, and Deposit Type 

Mt Todd is situated within the southeastern portion of the Early Proterozoic Pine Creek Geosyncline. Meta-sediments, 
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  moderate  westerly  dipping  axial  planes  with  some  sections  being 
overturned.    A  later  north-south  compression  event  resulted  in  east-west  trending  open  style  upright  D2  folds.    The 
Finniss River Group has been regionally metamorphosed to lower green schist facies.  Late and Post Orogenic granite 
intrusions of the Cullen Batholith occurred from 1,789 Ma to 1,730 Ma, and brought about local contact metamorphism 
to hornblende hornfels facies.  

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

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

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

Exploration Licenses 

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

The exploration effort initially focused on follow up work on targets developed by Pegasus during their tenure on the 
property.   These  included  the  RKD  target,  Tablelands,  and  Silver  Spray.   During  a  review  of  Pegasus’  airborne 
geophysical survey data, five distinct magnetic highs were observed located within sedimentary rocks that should have a 
low  magnetic  signature.   These  features  are  remarkably  similar  to  those  at  Batman,  which,  as  a  result  of  the  included 
pyrrhotite, exhibits a strong magnetic high.  The geophysical targets were prioritized following review of historic work 
in the area and site visits.  To date, two of the geophysical targets, Golden Eye and Snowdrop, have been drilled and a 
third, Black Hill, has been covered by soil sampling.  

32 

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

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

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

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

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

Based  on  Tetra  Tech’s  resource  analysis,  at  a  cut-off  grade  of  0.40  g  Au/t,  under  SEC Industry  Guide  7 guidelines, 
mineralized  material  for  the  Quigleys  deposit  is  estimated  at  6.2  million tonnes  grading  1.13  g  Au/t.  Under  CIM 
Definition  Standards,  at  the  same  cut-off  grade  of  0.40  g  Au/t,  measured  mineral  resources  are  estimated  at  457,000 
tonnes  grading  1.27  g  Au/t,  indicated  mineral  resources  are  estimated  at  5.7  million tonnes  grading  1.12  g  Au/t  and 
inferred mineral resources are estimated at 1.6 million tonnes grading 0.84 g Au/t. Cautionary Note to Investors: see the 
section heading “Cautionary Note to Investors Regarding Estimates of Measured, Indicated and Inferred Resources and 
Proven and Probable Reserves” above.

Drilling 

The drilling discussed in this section is related to the MLs and is limited to that completed since the filing of the NI 43-
101 Technical Report – Mt Todd Gold Project, 50,000 tpd Preliminary Feasibility Study, Northern Territory, Australia, 
Amended & Restated; July 7, 2014. A portion of the drillhole data was used to complete the resource estimate in August 
2017.  Part of the drillholes were completed for metallurgical samples and are not used in the mineral resource estimate.  
All of the drillhole data presented in the above report are still valid and have been incorporated in an unchanged manner. 

Between the fourth quarter of 2012 and the end of the first quarter of 2017, the Vista exploration program at the Batman 
deposit consisted of 22 diamond core drillholes containing 12,530 meters that targeted both infill definitional drilling and 
step-out drilling.

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

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

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

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

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

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

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

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

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

indicated in the core tray at the appropriate locations; 

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

indefinitely; and 

35 

 
 
 
 
 
 
 
 
 

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

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

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

The following laboratories have been used for lab preparation, analyses, and check assays:

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

Vista is completely independent of any analytical testing entity, other than they have engaged said entities as a customer. 

Sample Security 

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

36 

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

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

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

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

Mining Operations 

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

The Base Case and the Alternate Case use substantially the same sized equipment, however, the Alternate Case requires 
fewer units. 

39 

 
 
 
 
 
 
 
 
 
 
Mineral Processing  

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

The  flowsheet  for  the  Alternate  Case  is  based  on  the  same  configuration,  but  with  proportionally  smaller  scale 
equipment and fewer sorters and tanks.  

Metallurgical Testing 

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

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

40 

 
 
 
 
 
 
 
 
 
Ore Hardness 

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

The test results indicate the following: 

  The BWi for the XRT products was higher than the composite samples prepared from the crushed products.  
Hence,  it  is  reasonable  to  conclude  that  the  uncrushed  material  in  the  HPGR  is  harder  than  the  crushed 
product. 

  The waste material had a BWi higher than the composite sample as well as the XRT recycle products. 

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

primary ball mill circuit. 

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

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

HPGR Crusher Selection 

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

The  test  work  also  assessed  the  difference  in  power  requirements  between  a  primary/SAG/ball  mill  circuit,  a 
conventional 3-stage crush/ball mill circuit, and a 3-stage HPGR crush/ball mill circuit (with 3rd stage HPGR crushing 
and 2-stage grinding) to generate a P80 passing 60 μm product.   

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

Sorting 

The  bulk  automated  sorting  tests  comprised  four,  five-tonne  composites  prepared  from  3.75"  drill  core.   Three  of  the 
composites  contained  predominately  sulfide  mineralization  and  one  composite  contained  mixed  oxide/sulfide  material 
that  is  encountered  on  the  periphery  of  the  deposit.   The  drill  core  was  HPGR  crushed  and  screened  at  16mm  at  the 
facilities  of  Thyssen  Krupp  Industries  (“TKI”)  near  Dusseldorf,  Germany.   The  +16mm  material  was  sent  to  the  test 
facility  of  Tomra  Sorting  Solutions  (“Tomra”)  near  Hamburg,  Germany  where  this  material  was  initially  sorted using 
XRT  sorting.   A  total  of  12  sorting  tests  were  completed.   The  XRT  rejects  were  then  subjected  to  laser  sorting  to 
produce a final reject.  All material (-16mm HPGR crushed, XRT product, laser product and sorting reject) was sent to 
the  metallurgical  laboratory  of  Resource  Development  Inc.  (“RDi”)  in  Wheatridge,  Colorado  for  subsequent  sample 
preparation, assaying and additional metallurgical testing. 

On a material  mass basis, the combined XRT and laser sorting tests confirmed the Company’s expectation that it can 
reject approximately 10% of the run-of-mine feed as waste (test results range from 6.8% to 11.0%).  The average grade 
of the rejected material is estimated to be 0.12 g Au/t (results range from 0.06 g Au/t to 0.23 g Au/t) compared to the 
mine  cut-off  grade  of  0.4  g  Au/t,  resulting  in  a  gold  loss  from  the  rejected  waste  of  approximately  1.3%.   The 
improvement in mill feed grade is expected to be approximately 8%, resulting in run-of-mine average mill feed grade of 
0.91 g Au/t compared to the life-of-mine reserve grade of 0.84 g Au/t.  We now expect total costs for grinding, leaching

and  tailings  handling,  which  are  dependent  on  the  volume  of  material  processed,  to  be  approximately  10%  less  than 
previously estimated. 

Gold Recoveries 

We continued evaluating gold recoveries using two-stage grinding and a finer product size. This test work has confirmed 
that the introduction of sorting to reduce the leach tonnage by approximately 10% and finer grinding to P80 of 60 µm 
yields an increase in recovery of approximately 4.1%, net of solution losses.   

A  total  of  41  additional  leach  tests  were  completed  using  the  above  mentioned  two-staged  grinding  to  confirm  our 
resulting leach recoveries of 86.5% for sulfide ores, 79.5% for mixed and oxide ores and 71.5% for heap leach ore, net 
of solution losses. This test work has also confirmed a cyanide consumption rate of 0.45 kg per tonne.  

Our  recovery  plant  design  utilizing  a  conventional,  industry-proven,  CIP  circuit  remains  unchanged.  See  also  ‘2018 
Program Results’ below. 

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 Tetra Tech created a 3D resource model that has an average grade of 0.54 g 
Au/t. 

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

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 the size of P80 of 90 μm and pre-treated with lime and 
100 g/t of lead nitrate to suppress copper leaching.  The material was then leached for 24 hours.  These results support 
recovery rates of 71.5% 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 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  is  expected  to  contain  approximately  87  million  tonnes  of  material 
processed; 
an  existing  fresh  water  storage  reservoir  that  will  receive  a  two-meter  dam  raise  and will  harvest  stormwater 
sufficient to provide process water for year-round operations for a 50,000 tpd operation; 
a  natural  gas  pipeline  at  site  that  can  supply  sufficient  natural  gas  to  meet  the  project's  energy  requirements 
which,  coupled  with  the  planned  power  generating  plant,  would  save  considerably  on  project  operating  costs 
compared to grid-supplied power; 
a paved road to site; 
current electrical connection to the NT electric grid; and 
reduced earthworks costs due to the process plant location being the same as the previous process plant, which 
has already been cleared and graded. 

42 

 
 
 
 
 
 
 
 
 
 
 
Other benefits of Mt Todd’s NT location include: 

 
 
 

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

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

Planned infrastructure for the site includes the following: 

  Ammonium Nitrate and Fuel Oil (ANFO) Facility; 

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

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

  Heap Leach Facility; 

  Small Accommodation Camp for occasional contractor use; 

  Water Treatment Plant (WTP); 

  Power Supply; 

  Pit Dewatering; 

  Mine Services; 

  Communications; 

  Gatehouse; and 

  Expanded existing and additional TSF.  

Permitting 

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

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

In November 2018, we applied for the MMP permit, the operating permit that sets out how mine operating strategy will 
be  implemented  throughout  the  mine  life  in  compliance  with  the  EIS  and  Australian  Environmental  Protection  and 
Biodiversity Conservation Act of 1999 (“EPBC”) requirements.  

Environmental, Social and Community Factors 

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

43 

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

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

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

Water Treatment 

We have a WDL from the NT Government that authorizes the release of treated water from the Mt Todd site during the 
wet season in accordance with higher environmental protection standards. We operate in compliance with the standards. 
We will have to dewater substantially the entire pit before mining operations can be started.  

2018 Program Results 

In January 2018, we announced that the “authorization of a controlled activity” at Mt Todd, as required under the EPBC, 
as  it  relates  to  the  Gouldian Finch,  had  been  approved by  the  Australian  Commonwealth  Department  of  Environment 
and Energy. With this authorization, Vista has all the major environmental approvals necessary to allow development of 
Mt Todd. 

During 2018, we completed four additional PQ core holes designed to extract approximately 6 tonnes of higher-grade 
material  from  the  Batman  pit,  for  the  completion  of  two  additional  2.5  tonne  bulk  HPGR  crushing,  XRT  and  laser 
sorting tests using the same equipment as previous test work; and a single 1 tonne sample for completing an HPGR test 
with  a  competing  HPGR  manufacturer.  The  two  2.5  tonne  tests  were  conducted  to  confirm  the  efficiency  of  sorting 
higher-grade  ores.  We  are  completing  additional  feasibility-study-level  grinding  tests  with  the  manufacturers  of  the 
secondary  grinding  mills  in  order  to  obtain  material  for  ongoing  metallurgical  studies  and  specific  operating  data  for 
future design and evaluation work. Similar tests on low-grade samples were conducted earlier this year with Glencore, 
who  manufacture  the  ISAMill  referenced  in  the  PFS,  and  with FLSmidth, who produce  a  competing  mill  known  as  a 
Vertimill. We have also completed additional testing with an impeller manufacturer in order to optimize the design of 
the leach tanks to achieve the lowest possible electrical power consumption at designed slurry densities. 

In August 2018, we announced the results of tests of the second stage grinding circuit undertaken, under the direction of 
Resource Development Inc. These tests suggest that the Mt Todd ore can be efficiently ground to a finer final product 
size with lower power consumption than estimated in the PFS. Leaching the finer final product size material has again 
confirmed higher recoveries at finer grind sizes. Based on these initial results, we are now undertaking additional testing 
to:  confirm  results  over  a  broad  range  of  feed  grades;  justify  design  changes;  and  support  an  update  of  the  project 
economics.  We  believe  that  the  results  of  these  ongoing  grinding  and  leaching  tests  indicate  that  gold  recoveries 
exceeding 90% may be achieved for the Mt Todd gold project, as compared to 86.4% assumed in our January 2018 PFS. 
Analysis indicates that each 1% improvement in gold recoveries could add approximately 0.5% to Mt Todd’s after-tax 
IRR, and approximately $25 million to after-tax NPV5%. 

2019 Plans 

Our 2019 plans include completion of the metallurgical program started in 2018.  Specifically, completion of additional 
grinding studies, two-stage leach recoveries, and rheology studies. Upon completion of the confirmation metallurgical 
test work, Vista intends to update the January 24, 2018 PFS by incorporating the metallurgical test program results.  The 
areas of the PFS that will likely be most impacted include higher gold recoveries due to the introduction of a constant tail 
and lower process plant operating costs with regard to power consumption, reagents, and media.

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

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

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

Pursuant to the terms of the Option Agreement, we have granted Minera Alamos an exclusive right and option to earn a 
100% interest in the GdlR Project by: 

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

  maintaining the concessions comprising the GdlR Project in good standing; 
 

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

 

 

 

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

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

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

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

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

ITEM 3.  LEGAL PROCEEDINGS. 

We are not aware of any material pending litigation or of any proceedings known to be contemplated by governmental 
authorities  that  are,  or  would  be,  likely  to  have  a  material  adverse  effect  upon  us  or  our  operations,  taken  as 
a whole.  There are no known material proceedings pursuant to which any of our directors, officers or affiliates or any 
owner of record or beneficial owner of more than 5% of our securities or any associate of any such director, officer or 
security holder is a party adverse to us or has a material interest adverse to us.  

ITEM 4.  MINE SAFETY DISCLOSURES. 

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

Pursuant to Section 1503(a) of the United States Dodd-Frank Wall Street Reform and Consumer Protection Act of 2011 
(the “Dodd-Frank Act”), issuers that are operators, or that have a subsidiary that is an operator, of a coal or other mine in 
the  United  States  are  required  to  disclose  in  their  periodic  reports  filed  with  the  SEC  information  regarding  specified 
health  and  safety  violations,  orders  and  citations,  related  assessments  and  legal  actions,  and  mining-related  fatalities 
under the regulation of the Federal Mine Safety and Health Administration (“MSHA”) under the United States Federal 
Mine  Safety  and  Health  Act  of  1977  (the  “Mine  Act”).  During  the  fiscal  year  ended  December  31,  2018,  we  had  no 
properties in the United States and were not subject to regulation by the MSHA under the Mine Act and consequently no 
disclosure is required under Section 1503(a) of the Dodd-Frank Act.

Exchange Controls 

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

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

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

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

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

(v) 
(vi) 
(vii) 

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

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

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

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

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

(i) 

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

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

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

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

48 

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

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

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

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

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

In  July  2018,  the  Company  amended  certain  2013  stock  option  agreements,  expiring  December  30,  2018 
subject to the potential for a temporary extension under the terms of the Plan, for seven executives and directors 
(the “Option Amendment”). The amendment provided each grantee the opportunity to receive a cash buyout of 
certain vested, unexercised 2013 options in lieu of exercising the option to purchase shares. This cash buyout 
was  based  on  the  intrinsic  value  of  each  option  at  the  time  of  the  buyout  as  determined  by  the  Company’s 
Compensation Committee prior to the buyout. In December 2018, all 502,500 of the options under the Option 
Amendment  were  settled  with  cash  buyouts  totaling  $61,  representing  an  average  price  per  the  underlying 
shares of $0.12, and the related options were cancelled by the Company.  The buy back was approved by the 
Company’s Board of Diectors and Compensation Committee and was funded through cash on hand from the 
Company’s available surplus. Other than these private transactions, the Company’s Board of Directors has not 
authorized any stock repurchase program or plan and the Company has no current plans of making any open-
market purchases of its common shares or other repurchases of equity securities.

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

The following discussion and analysis should be read in conjunction with our consolidated financial statements for the 
two years ended December 31, 2018 and 2017, and the related notes thereto, which have been prepared in accordance 
with  generally  accepted  accounting  principles  in  the  United  States  (“U.S.  GAAP”).  This  discussion  and  analysis 
contains  forward-looking  statements  that  involve  risks,  uncertainties  and  assumptions.  Our  actual  results  may  differ 
materially  from  those  anticipated  in  these  forward-looking  statements  as  a  result  of  many  factors,  including,  but  not 
limited to, those set forth under the section heading “Item 1A. Risk Factors” above and elsewhere in this annual report 
on Form 10-K.  See section heading “Note Regarding Forward-Looking Statements” above. 

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

Overview 

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

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

Results from Operations 

Summary 

Through 2018, we continued to improve the economics of the Mt Todd gold project at a relatively low cost. In August 
2018, we announced the results of tests of the second stage grinding circuit undertaken, under the direction of Resource 
Development Inc. These tests suggest that the Mt Todd ore can be efficiently ground to a finer final product size with 
lower power consumption than estimated in the PFS. Leaching the finer final product size material has again confirmed 
higher  recoveries  at  finer  grind  sizes.  Based  on  these  initial  results,  we  are  now  undertaking  additional  testing  to: 
confirm  results  over  a  broad  range  of  feed  grades;  justify  design  changes;  and  support  an  update  of  the  project 
economics.  We  believe  that  the  results  of  these  ongoing  grinding  and  leaching  tests  indicate  that  gold  recoveries 
exceeding 90% may be achieved for the Mt Todd gold project, as compared to 86.4% assumed in our January 2018 PFS. 
Analysis indicates that each 1% improvement in gold recoveries could add approximately 0.5% to Mt Todd’s after-tax 
IRR, and approximately $25 million to after-tax NPV5%.

Consolidated net loss for the year ended December 31, 2018 was $8,714 or $0.09 per basic share. Consolidated net loss 
for the year ended December 31, 2017 was $12,035 or $0.12 per basic share. The principal components of our 2018 net 
loss and these year-over-year changes are discussed below. 

The Company has $13,198 of working capital and no debt. 

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  $4,803  and  $6,931  during  the  years  ended  December  31,  2018  and  2017, 
respectively. These costs are predominantly associated with Mt Todd and are comprised of fixed costs and discretionary 
costs. For the years ended December 31, 2018 and 2017, our fixed costs (which include cash expenditures necessary to 
ensure  that  we  preserve  our  property  rights  and  meet  all  of  our  safety,  regulatory  and  environmental  responsibilities) 
trended approximately 10% higher in 2018 compared to 2017 as baseline monitoring activities have been introduced as 
part  of  our  compliance  with  the  terms  of  the  permit  granted  under  the  Australian  Environmental  Protection  and 
Biodiversity  Conservation  Act  of  1999  (“EPBC”)  in  January  2018.    In  addition,  we  have  added  site  employees  to 
complement  site  environmental,  maintenance  and  exploration  activities.  We  expect  2019  fixed  costs  to  remain 
substantially unchanged from 2018 fixed costs.     

Mt  Todd  2018  discretionary  programs  totaled  approximately  $1,200,  principally  for  additional  ore  sorting  testing  and 
drilling programs at Quigleys and on the ELs. This is significantly lower than the 2017 discretionary programs which 
totaled  approximately  $3,500.  The  2017  discretionary  programs  included  large-scale  ore  sorting  tests  with  subsequent 
metallurgical and grinding studies, and substantial completion of the 2018 PFS update. Currently planned discretionary 
programs total approximately $425 and include completion of the metallurgical programs started in 2018 and an update 
to January 24th, 2018 PFS. 

Included in the 2018 and 2017 exploration, property evaluation and holding costs is non-cash stock-based compensation 
of $249 and $260 respectively.  

Corporate administration  

Corporate  administration  costs  were  $4,072  and  $3,527  during  the  years  ended  December  31,  2018  and  2017, 
respectively.  Higher  2018  investor  relations,  regulatory  and  compensation  costs  were  incurred  as  a  result  of  the 
completion of the Mt Todd PFS update. In addition, insurance coverage was increased in 2018, resulting in higher 2018 
insurance costs.  We expect 2019 costs to trend approximately 5% to 10% lower than 2018 costs.     

Included in the 2018 and 2017 corporate administration costs is non-cash stock-based compensation of $733 and $614 
respectively. 

Depreciation 

Depreciation costs were $983 and $655 during the years ended December 31, 2018 and 2017, respectively. Depreciation 
in  2018  includes  $695  to  adjust  the  net  book  value  of  plant  and  equipment  to  account  for  the  cumulative  effect  of 
immaterial calculation differences in prior years. 

Impairment of Used Mill Equipment 

The  Company’s  efforts  to  sell  its  used  mill  equipment  over  the  past  several  years  have  been  unsuccessful.    As  of 
December 31, 2018, there are no prospects for an imminent sale of this equipment, and the market conditions conducive 
to such a sale are not expected to improve in the near future.  Based on an independent valuation by a qualified third 
party,  and  allowing  for  selling  commissions  and  costs,  the  Company  has  recorded  a  Level  3  impairment  charge  of 
$1,000,  which  has  been  included  in  our  Consolidated  Statements  of  Income/(Loss)  for  the  year  ended  December  31, 
2018. There was no similar charge for the year ended December 31, 2017.

Gain on disposal of mineral property 

Long Valley claims 

During  the  first  quarter  of  2017,  we  sold  our  Long  Valley  unpatented  mining  claims  located  in  California  for 
consideration, net of transaction costs, of $358 which was paid at closing; a future payment of $500 one month after the 
start of commercial production; a future payment of $500 on or prior to the first anniversary of the start of commercial 
production;  and  a  net  smelter  return  royalty  (“NSR”)  on  any  future  production  from  said  claims  at  a  variable  rate 
between 0.5% and 2.0%, depending on the average gold price realized. This sale resulted in a realized gain of $358.  

Non-operating income and expenses   

Gain/(loss) on Other Investments 

Gain/(loss)  on  other  investments  was  $1,716  and  $(1,248)  for  the  years  ended  December  31,  2018  and  2017, 
respectively.  These amounts are the result of changes in fair value of our Midas Gold Shares. There were no share sales 
during the years ended December 31, 2018 and 2017.  

Financial Position, Liquidity and Capital Resources 

Operating Activities 

Net  cash  used  in  operating  activities  was  $8,567  and  $8,801  for  the  years  ended  December  31,  2018  and  2017, 
respectively.    Although  exploration,  property  evaluation  and  holding  costs  (including  discretionary  programs)  and 
corporate administration costs, in total, were approximately $1,583 lower in 2018 than in 2017, as discussed in “Results 
from  Operations”  above,  a  total  of  approximately  $1,186  was  used  in  2018  to  reduce  accounts  payable  and  accrued 
liabilities  that  resulted from  relatively  high  discretionary  program  activity,  including  completion  of  the  PFS update  in 
late in 2017.   

Investing Activities 

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

Cash  provided  by  investing  activities  for  the  year  ended  December  31,  2017  was  primarily  due  to  the  redemption  of 
short-term investments comprised of U.S. Government Treasury bills and notes, net of purchases, of $6,831. Proceeds of 
$1,761, net of legal costs, were received from the first option payment for the Guadalupe de los Reyes gold/silver project 
and the Long Valley gold claims (discussed in “Note 4 of the Consolidated Financial Statements” below). 

Financing Activities 

Net cash of $122 for 2018 was utilized for the payment of certain employee withholding tax obligations in lieu of the 
issuance of common shares and $86 was received from exercised stock options. 

Net cash of $264 for 2017 was utilized for the payment of certain employee withholding tax obligations in lieu of the 
issuance of common shares. 

Liquidity and Capital Resources 

Our cash and short-term investments as of December 31, 2018 decreased to $8,068 from $16,575 at December 31, 2017 
due mainly to operating activities as discussed above. Our net working capital decreased to $13,198 as at December 31, 
2018  from  $19,057  at  December 31,  2017  due  mainly  to  the  decrease  in  cash  and  short-term  investments  to  fund 
operating activities, partially offset by an increase in the market value of our Midas Gold Shares.  

53 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
We  believe  that  our  existing  working  capital,  together  with  potential  future  sources  of  non-dilutive  financing,  will  be 
sufficient to fully fund our currently planned fixed costs and discretionary programs into 2020.   

Potential future sources of non-dilutive financing include the sale of non-core assets such as our used mill equipment and 
future option payments for the Guadalupe de los Reyes gold/silver project; and, depending on market conditions, the sale 
of some or all of our Midas Gold Shares.     

In  addition  to  the  potential  for  non-dilutive  financing,  during  November  2017,  the  Company  entered  into  an  at-the-
market  offering  agreement  (the  “ATM  Agreement”)  with  H. C.  Wainwright &  Co.,  LLC  (“Wainwright”)  to  provide 
additional balance sheet flexibility at a low cost. Under the ATM Agreement the Company may, but is not obligated to, 
issue and sell shares of the Company’s common stock through Wainwright as sales manager in an at-the-market offering 
under  a  prospectus  supplement  for  aggregate  sales  proceeds  of  up  to  $10,000  (the  “ATM  Program”).   The  ATM 
Agreement will remain in full force and effect until the earlier of August 31, 2020, or the date that the ATM Agreement 
is terminated in accordance with the terms therein. Offers or sales of common shares under the ATM Program will be 
made only in the United States and no offers or sales of common shares under the Agreement will be made in Canada. 
The  common  stock  will  be  distributed  at-the-market  prices  prevailing  at  the  time  of  sale.  As  a  result,  prices  of  the 
common stock sold under the ATM Program may vary during the period of distribution. The ATM Agreement provides 
that Wainwright will be entitled to compensation for its services at a commission rate of 2.0% of the gross sales price per 
share of common stock sold.  The Company reimbursed certain legal expenses of Wainwright totaling $50 and incurred 
additional  accounting,  legal,  and  regulatory  costs  of  approximately  $156  in  connection  with  establishing  the  ATM 
Program.  Such costs were expensed as incurred during 2017.  At December 31, 2018 no offers or sales had been made 
under the ATM Program.  

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 or sales  of  assets. The  underlying value  and  recoverability  of  the 
amounts shown as mineral properties and plant and equipment in our 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 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 mill equipment is classified as Level 3 of the fair value hierarchy as its value at December 31, 2018 and 2017 was 
based  on  an  independent  third-party  valuation.  The  mill  equipment  is  included  in  plant  and  equipment  on  the 
Consolidated Balance Sheets for each period presented.   

There were no transfers between levels nor were there any changes in valuation techniques in 2018. 

Off-Balance Sheet Arrangements 

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

Contractual Obligations 

We have no material contractual obligations as of December 31, 2018.

Critical Accounting Policies and Recent Accounting Pronouncements 

Critical 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. 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;  useful  lives  of  assets  for  asset  depreciation  purposes;  valuation  allowances  for 
deferred  tax  assets;  the  fair  value  and  accounting  treatment  of  stock-based  compensation;  the  provision  for 
environmental  liabilities;  and  asset  impairments.  The  Company  bases  its  estimates  on  historical  experience  and  on 
various other assumptions  that  are believed  to be reasonable under  the circumstances.  Accordingly, actual  results will 
likely differ from the amounts estimated in these financial statements.  

Cash and cash equivalents 

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

Foreign Currency Transactions 

Our  functional  currency  is  the  U.S.  dollar.  Foreign  currency  transactions  denominated  in  currency  other  than  the 
functional  currency  are  recorded  at  the  approximate  rate  of  exchange  at  the  transaction  date  and  any  gains/(losses) 
resulting  therefrom  are  recorded  in  other  expense.  For  each  of  the  years  ended  December  31,  2018  and  2017,  we 
recorded insignificant net foreign currency gains/(losses).  

Short-term Investments 

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

Mineral Properties 

Mineral property acquisition costs, including directly related costs, are capitalized when incurred, and mineral property 
exploration costs are expensed as incurred.  When we determine that a mineral property can be economically developed 
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 sufficient 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 

56 

 
 
 
 
 
 
 
 
 
 
 
information  and/or  third-party  valuation  experts  to  assess  if  the  carrying  value  can  be  recovered  and  to  estimate  fair 
value.  

Impairment  

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

Stock-Based Compensation 

Under  our  stock  option  and  long-term  equity  incentive  plans,  stock  incentive  options,  and  until  April  2018,  restricted 
stock units could 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. The fair value of restricted stock units is based on the closing price of our common 
shares on the grant date. The expense is based on the fair values of the grant on the grant date and is recognized over the 
vesting period specified for each grant. Forfeitures for all stock-based compensation are recorded when incurred.   

Financial Instruments 

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

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

unrestricted assets or liabilities.  

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

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

and unobservable.  

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

Leases 

In  February  2016  the  FASB  issued  ASU  No.  2016-02,  Leases.  The  new  standard  establishes  a  right-of-use  (“ROU”) 
model that requires a lessee to record an ROU asset and a lease liability on the balance sheet for all leases with terms 
longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of 
expense  recognition  in  the  income  statement.  The  new  standard  is  effective  for  interim  and  annual  periods  beginning 
after December 15, 2018. A modified retrospective transition approach is required for lessees for capital and operating 
leases  existing  at,  or  entered  into,  after  the  beginning  of  the  earliest  comparative  period  presented  in  the  financial 
statements, with certain practical expedients available. Based upon our initial review, we expect to recognize additional 
operating liabilities of approximately $185 on adoption, with corresponding ROU assets of the same amount, based on 
the present value of the remaining lease payments. 

Nonemployee Share-Based Payments 

The FASB issued ASU No. 2018-07, Compensation - Stock Compensation (Topic 718) - Improvements to Nonemployee 
Share-Based  Payment  Accounting.  ASU  No.  2018-07,  supersedes  the  guidance  for  equity-based  payments  to 
nonemployees  (Topic  ASC  505-50).  Under  the  new  standard,  an  entity  should  treat  equity-based  payments  to 
nonemployees  the  same  as  stock-based  compensation  to  employees  in  most  cases.  The  new  guidance  is  effective  for 
interim and annual periods beginning after December 15, 2018, with early adoption permitted. Effective July 1, 2018, 
the Company adopted the new guidance. The Company performed an assessment of the standard and the impacts on the 
Company’s Consolidated Financial Statements and disclosures. Based on our analysis, adoption of the standard has not 
materially changed the Company’s expense recognition and disclosures. 

Revenue Recognition 

New  FASB  guidance  issued  under  ASU  No.  2014-09,  Revenue  from  Contracts  with  Customers  (Topic  606),  as 
amended, is effective for interim and annual periods beginning after December 15, 2017. Under ASU No. 2014-09, an 
entity should recognize revenue when it transfers promised goods or services to customers in an amount that reflects the 
consideration to which the entity expects to be entitled in exchange for those goods or services. ASU No. 2014-09 also 
requires additional disclosure about the nature, amount, timing, and uncertainty of revenue and cash flows arising from 
customer  contracts.  This  includes  significant  judgments  and  changes  in  judgments  and  assets  recognized  from  costs 
incurred to obtain or fulfill a contract. 

Effective January 1, 2018, the Company adopted the new guidance modified retrospectively. The Company performed 
an  assessment  of  the  revised  guidance  and  the  impacts  on  the  Company’s  Consolidated  Financial  Statements  and 
disclosures. We also evaluated the potential for future variable consideration from option payments, net smelter return 
royalties  (“NSR”),  and  other  production  related  payments,  and  determined  that  there  is  no  impact  to  the  Company’s 
current  accounting.  The  Company  determined  that  the  adoption  of  this  guidance  will  primarily  impact  the  timing  of 
revenue recognition on certain option agreements based on the Company’s determination of when control is transferred 
for accounting purposes. Based on the contracts outstanding as of December 31, 2017, there was no cumulative effect 
adjustment required to be recognized at January 1, 2018. Under the Company’s adoption approach, results for reporting 
periods  beginning  after  January  1,  2018,  will  be  presented  in  the  Consolidated  Financial  Statements  under  the  new 
guidance, while prior period amounts will not be adjusted and continue to be reported under the guidance in effect for 
those periods. 

Currently, proceeds received from option agreements are ascribed to recovery of the carrying value of the related project 
until  the  carrying  value  reaches  zero.  After  that,  any  additional  proceeds  received  will  be  recognized  as  a  contract 
liability until control has transferred to the buyer or the related contract has terminated. None of the projects which could 
provide the Company with future variable consideration are currently in production, and in all cases, we believe there is 
low  probability  of  future  production  from  these  projects.  Accordingly,  the  Company  believes  its  NSRs  and  other 
production  related  payments  are  fully  constrained,  and  the  Company  did  not  record  a  receivable  for  them.  When  it 

58 

 
 
 
 
 
 
 
 
becomes probable that a project which could provide the Company with an NSR or other production related payments 
could begin production, the Company will evaluate the accounting treatment at that time. 

ITEM 8.  FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA. 

Management’s Report on Internal Control Over Financial Reporting  

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

The  Company’s  management  assessed  the  effectiveness  of  the  Company’s  internal  control  over  financial  reporting  at 
December 31, 2018. 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,  2018,  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, 2018 has 
been audited by Plante & Moran, PLLC, an independent registered public accounting firm, as stated in their report which 
appears herein.

Opinion on the Financial Statements 

We have audited the accompanying consolidated balance sheet of Vista Gold Corp. (the “Company”) as of December 
31, 2018, the related consolidated statements of income/(loss), comprehensive income/(loss), shareholders' equity, and 
cash flows for the year then ended, and the related notes (collectively referred to as the “financial statements”). In our 
opinion,  the  financial  statements  referred  to  above  present  fairly,  in  all  material  respects,  the  financial  position  of  the 
Company as of December 31, 2018, and the results of its operations and its cash flows for the year ended December 31, 
2018, in conformity with accounting principles generally accepted in the United States of America.  

We also have audited the Company’s internal control over financial reporting as of December 31, 2018, in accordance 
with the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”), based on criteria 
established in Internal Control-Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of 
the Treadway Commission (COSO). Our report dated February 21, 2019, expresses an unqualified opinion. 

Basis for Opinion 

The Company's management is responsible for these financial statements. Our responsibility is to express an opinion on 
the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB 
and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and 
the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. 

We  conducted  our  audits  in  accordance  with  the  standards  of  the  PCAOB.  Those  standards  require  that  we  plan  and 
perform  the  audit  to  obtain  reasonable  assurance  about  whether  the  financial  statements  are  free  of  material 
misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material 
misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those 
risks.  Such  procedures  included  examining,  on  a  test  basis,  evidence  regarding  the  amounts  and  disclosures  in  the 
financial statements. Our audits also included evaluating the accounting principles used and significant estimates made 
by  management,  as  well  as  evaluating  the  overall  presentation  of  the  financial  statements.  We  believe  that  our  audits 
provide a reasonable basis for our opinion.

1. Nature of Operations 

Vista operates in the gold mining industry. We are focused on the evaluation, acquisition, exploration and advancement 
of  gold  exploration,  and  potential  development  projects,  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”) in the Northern Territory (“NT”) 
Australia.  Mt  Todd  is  the  largest  undeveloped  gold  project  in  Australia.  In  January  2018,  the  Company  received 
authorization for the last major environmental permit and we announced the positive results of an updated preliminary 
feasibility study (the “PFS”) for Mt Todd. Subsequently, Vista has completed additional metallurgical testing, including 
ongoing fine grinding evaluations, which demonstrate further improvements in gold recovery. We also hold 7.8 million 
of  the  outstanding  common  shares  in  the  capital  of  Midas  Gold  Corp.  (“Midas  Gold  Shares”),  a  non-core  project  in 
Mexico and royalty interests in the United States and Indonesia. 

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

2. Significant Accounting Policies 

Principles of Consolidation 

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

Use of Estimates 

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

Cash and cash equivalents 

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

Foreign Currency Transactions 

Our  functional  currency  is  the  U.S.  dollar.  Foreign  currency  transactions  denominated  in  currency  other  than  the 
functional  currency  are  recorded  at  the  approximate  rate  of  exchange  at  the  transaction  date  and  any  gains/(losses) 
resulting  therefrom  are  recorded  in  other  expense.  For  each  of  the  years  ended  December  31,  2018  and  2017,  we 
recorded insignificant net foreign currency gains/(losses).  

Short-term Investments 

66 

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

Mineral Properties 

Mineral property acquisition costs, including directly related costs, are capitalized when incurred, and mineral property 
exploration costs are expensed as incurred.  When we determine that a mineral property can be economically developed 
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 sufficient 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). 

Stock-Based Compensation 

Under  our  stock  option  and  long-term  equity  incentive  plans,  stock  incentive  options,  and  until  April  2018,  restricted 
stock units could 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. The fair value of restricted stock units is based on the closing price of our common 
shares on the grant date. The expense is based on the fair values of the grant on the grant date and is recognized over the 
vesting period specified for each grant. Forfeitures for all stock-based compensation are recorded when incurred.   

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 

67 

 
 
 
 
 
 
 
 
 
 
 
of  unobservable  inputs  when  measuring  fair  value.  ASC  820  establishes  a  fair  value  hierarchy  based  on  the  level  of 
independent,  objective  evidence  surrounding  the  inputs  used  to  measure  fair  value.  A  financial  instrument’s 
categorization within the fair value hierarchy is based upon the lowest level of input that is significant to the fair value 
measurement. ASC 820 prioritizes the inputs into three levels that may be used to measure fair value: 

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

unrestricted assets or liabilities.  

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

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

and unobservable.  

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

Recent accounting pronouncements   

Leases 

In  February  2016  the  FASB  issued  ASU  No.  2016-02,  Leases.  The  new  standard  establishes  a  right-of-use  (“ROU”) 
model that requires a lessee to record an ROU asset and a lease liability on the balance sheet for all leases with terms 
longer than 12 months. Leases will be classified as either finance or operating, with classification affecting the pattern of 
expense  recognition  in  the  income  statement.  The  new  standard  is  effective  for  interim  and  annual  periods  beginning 
after December 15, 2018. A modified retrospective transition approach is required for lessees for capital and operating 
leases  existing  at,  or  entered  into,  after  the  beginning  of  the  earliest  comparative  period  presented  in  the  financial 
statements, with certain practical expedients available. Based upon our initial review, we expect to recognize additional 
operating liabilities of approximately $185 on adoption, with corresponding ROU assets of the same amount, based on 
the present value of the remaining lease payments. 

Nonemployee Share-Based Payments 

The FASB issued ASU No. 2018-07, Compensation - Stock Compensation (Topic 718) - Improvements to Nonemployee 
Share-Based  Payment  Accounting.  ASU  No.  2018-07,  supersedes  the  guidance  for  equity-based  payments  to 
nonemployees  (Topic  ASC  505-50).  Under  the  new  standard,  an  entity  should  treat  equity-based  payments  to 
nonemployees  the  same  as  stock-based  compensation  to  employees  in  most  cases.  The  new  guidance  is  effective  for 
interim and annual periods beginning after December 15, 2018, with early adoption permitted. Effective July 1, 2018, 
the Company adopted the new guidance. The Company performed an assessment of the standard and the impacts on the 
Company’s Consolidated Financial Statements and disclosures. Based on our analysis, adoption of the standard has not 
materially changed the Company’s expense recognition and disclosures. 

Revenue Recognition 

New  FASB  guidance  issued  under  ASU  No.  2014-09,  Revenue  from  Contracts  with  Customers  (Topic  606),  as 
amended, is effective for interim and annual periods beginning after December 15, 2017. Under ASU No. 2014-09, an 

68 

 
 
 
 
  
 
 
 
 
 
 
entity should recognize revenue when it transfers promised goods or services to customers in an amount that reflects the 
consideration to which the entity expects to be entitled in exchange for those goods or services. ASU No. 2014-09 also 
requires additional disclosure about the nature, amount, timing, and uncertainty of revenue and cash flows arising from 
customer  contracts.  This  includes  significant  judgments  and  changes  in  judgments  and  assets  recognized  from  costs 
incurred to obtain or fulfill a contract. 

Effective January 1, 2018, the Company adopted the new guidance modified retrospectively. The Company performed 
an  assessment  of  the  revised  guidance  and  the  impacts  on  the  Company’s  Consolidated  Financial  Statements  and 
disclosures. We also evaluated the potential for future variable consideration from option payments, net smelter return 
royalties  (“NSR”),  and  other  production  related  payments,  and  determined  that  there  is  no  impact  to  the  Company’s 
current  accounting.  The  Company  determined  that  the  adoption  of  this  guidance  will  primarily  impact  the  timing  of 
revenue recognition on certain option agreements based on the Company’s determination of when control is transferred 
for accounting purposes. Based on the contracts outstanding as of December 31, 2017, there was no cumulative effect 
adjustment required to be recognized at January 1, 2018. Under the Company’s adoption approach, results for reporting 
periods  beginning  after  January  1,  2018,  will  be  presented  in  the  Consolidated  Financial  Statements  under  the  new 
guidance, while prior period amounts will not be adjusted and continue to be reported under the guidance in effect for 
those periods. 

Currently, proceeds received from option agreements are ascribed to recovery of the carrying value of the related project 
until  the  carrying  value  reaches  zero.  After  that,  any  additional  proceeds  received  will  be  recognized  as  a  contract 
liability until control has transferred to the buyer or the related contract has terminated. None of the projects which could 
provide the Company with future variable consideration are currently in production, and in all cases, we believe there is 
low  probability  of  future  production  from  these  projects.  Accordingly,  the  Company  believes  its  NSRs  and  other 
production  related  payments  are  fully  constrained,  and  the  Company  did  not  record  a  receivable  for  them.  When  it 
becomes probable that a project which could provide the Company with an NSR or other production related payments 
could begin production, the Company will evaluate the accounting treatment at that time. 

3. Other Investments 

Short-term investments 

As of December  31,  2018  and 2017,  the  amortized  cost basis of our short-term  investments  was $6,997  and $15,144, 
respectively. The amortized cost basis approximates fair value at December 31, 2018 and 2017. Short-term investments 
at  December  31,  2018  and  2017  are  comprised  of  U.S.  Government  treasury  bills  and/or  notes,  all  of  which  have 
maturity dates greater than 90 days but less than one year. 

Other investments - Midas Gold Shares 

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, 2018 and 2017.

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

Pursuant to the terms of the Option Agreement, we granted Minera Alamos an exclusive right and option to earn a 100% 
interest in the GdlR Project by: 

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

  maintaining the concessions comprising the GdlR Project in good standing; 
 

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

 

 

 

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

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

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

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

During  2017,  we  sold  our  Long  Valley  unpatented  mining  claims  located  in  California  for  consideration,  net  of 
transaction costs, of $358 which was paid at closing; a future payment of $500 one month after the start of commercial 
production; a future payment of $500 on or prior to the first anniversary of the start of commercial production; and an 
NSR on any future production from said claims at a variable rate between 0.5% and 2.0% depending on the average gold 
price realized. This sale resulted in a realized gain of $358.

We  continue  to  actively  market  the  used  mill  equipment,  however,  we  do  not  classify  it  as  ‘held  for  sale’  on  our 
Consolidated  Balance  Sheets  as  of  December  31,  2018  or  2017  as  we  do  not  have  reasonable  assurance  that  the  mill 
equipment  will  sell  within  12  months.    We  are  not  currently  depreciating  the  used  mill  equipment  as  we  continue  to 
market it and it is not in use. The Company’s efforts to sell its used mill equipment over the past several years have been 
unsuccessful.  As of December 31, 2018, there are no prospects for an imminent sale of this equipment, and the market 
conditions conducive to such a sale are not expected to improve in the near future.  Based on an independent valuation 
by  a  qualified  third  party,  and  allowing  for  selling  commissions  and  costs,  the  Company  has  recorded  a  Level  3 
impairment  charge  of  $1,000,  which  has  been  included  in  our  Consolidated  Statements  of  Income/(Loss)  for  the  year 
ended December 31, 2018.  

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

Under the Company’s stock option plan (the “Plan”), we may grant options to purchase common shares of the Company 
(“Common  Shares”)  to  our  directors,  officers,  employees  and  consultants.  The  maximum  number  of  our  Common 
Shares that may be reserved for issuance under the Plan, together with RSUs currently outstanding under the Long-Term 
Incentive Plan (“LTIP”), is a variable number equal to 10% of the issued and outstanding Common Shares on a non-
diluted basis at any one time. Options under the Plan are granted from time to time at the discretion of the Board, with 
vesting  periods  and  other  terms  as  determined  by  the  Board.  Stock-based  compensation  expense  for  the  years  ended 
December 31, 2018 and 2017 is as follows:

No stock options were granted for the year ended December 31, 2017. The fair value of stock options granted during the 
year ended December 31, 2018 to employees, directors and consultants was estimated at the grant date using the Black-
Scholes option pricing model using the following assumptions:

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

Option Amendment 

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

During the years ended December 31, 2018 and 2017, the Company withheld shares equivalent to the value of employee 
withholding  tax  obligations  which  resulted  from  RSUs  vesting  in  the  period.    Shares  withheld  are  considered 
cancelled/forfeited.   

Under the LTIP, a portion of the RSU awards vest on a fixed future date provided the recipient continues to be affiliated 
with  Vista  on  that  date.  Other  RSU  awards  vest  subject  to  certain  performance  and  market  criteria,  including  the 
accomplishment  of  certain  corporate  objectives  and  the  Company’s  share  price  performance.  Of  the  unvested  RSUs, 
approximately 26% could vest based on a fixed future date, approximately 29% and 45% could vest on performance and 
market criteria respectively.  The vesting period for all RSUs is at least one year. New RSUs will not be granted under 
the LTIP until the allocation of such awards is duly approved by the shareholders of the Company.

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

During November 2017, the Company entered into an at-the-market offering agreement (the “ATM Agreement”) with 
H. C. Wainwright & Co., LLC (“Wainwright”), under which the Company may, but is not obligated to, issue and sell 
shares  of  the  Company’s  common  stock  through  Wainwright  as  sales  manager  in  an  at-the-market  offering  under  a 
prospectus supplement for aggregate sales proceeds of up to $10,000 (the “ATM Program”).  The ATM Agreement will 
remain in full force and effect until the earlier of August 31, 2020, or the date that the ATM Agreement is terminated in 
accordance with the terms therein. Offers or sales of common shares under the ATM Program will be made only in the 
United States and no offers or sales of common shares under the Agreement will be made in Canada. The common stock 
will be distributed at the market prices prevailing at the time of sale. As a result, prices of the common stock sold under 
the ATM Program may vary during the period of distribution. The ATM Agreement provides that Wainwright will be 
entitled to compensation for its services at a commission rate of 2.0% of the gross sales price per share of common stock 
sold.  The Company reimbursed certain legal expenses of Wainwright totaling $50 and incurred additional accounting, 
legal, and regulatory costs of approximately $156 in connection with establishing the ATM Program.  Such costs have 
been  expensed  as  incurred  during  2017.  At  December  31,  2018  and  December  31,  2017  no  offers  or  sales  had  been 
made under the ATM Program.

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.  

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

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 mill equipment is classified as Level 3 of the fair value hierarchy as its value at December 31, 2018 and 2017 was 
based  on  an  independent  third-party  valuation.  This  valuation  was  based  on  unobservable  inputs  obtained  by  our 
valuation  specialists  and  reviewed  by  the  Company.  The  mill  equipment  is  included  in  plant  and  equipment  on  the 
Consolidated Balance Sheets for each period presented.   

There were no transfers between levels nor were there any changes in valuation methods in 2017.  

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

As  of  December 31,  2018  and  2017,  all  of  our  cash  was  held  in  liquid  bank deposits  and/or  government  treasury 
bills/notes in the Unites States. 

There were no significant non-cash transactions for the year ended December 31, 2018 or 2017.

liabilities for financial reporting purposes and the amounts used for income tax purposes. The significant components of 
our deferred tax assets and liabilities as at December 31 are as follows:

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 $56,659 and $51,406 at December 
31,  2018  and  2017,  respectively,  relates  mainly  to  net  operating  loss  carryforwards,  in  Canada  and  other  foreign  tax 
jurisdictions, where the utilization of such attributes is not more likely than not.  The Company continually assesses both 
positive and negative evidence to determine whether it is more likely than not that deferred tax assets can be realized 
prior to their expiration.

Accounting for uncertainty in taxes 

Accounting  Standards  Codification  Topic  740  guidance  requires  that  the  Company  evaluate  all  income  tax  positions 
taken, and recognize a liability for any uncertain tax positions that are not more likely than not to be sustained by the tax 
authorities.  As of December 31, 2018, 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, 
2015 or U.S. federal income tax examinations by the Internal Revenue Service for years ended on or before December 
31, 2015.  Some U.S. state and other foreign jurisdictions are still subject to tax examination for years ended on or before 
December 31, 2014. 

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

12. Geographic and Segment information 

The  Company  has  one  reportable  operating  segment,  consisting  of  evaluation,  acquisition,  and  exploration  activities.  
We evaluate, acquire, explore and advance gold exploration and potential development projects, which may lead to gold 
production  or  value  adding  strategic  transactions.  These  activities  are  currently  focused  principally  in  Australia.  We 
reported no revenues during the years ended December 31, 2018 or 2017.  Geographic location of mineral properties and 
plant and equipment is provided in Notes 4 and 5, respectively.  

13. Provision for Environmental Liability  

During  2016,  the  Province of  British  Columbia  Ministry  of  Energy  and  Mines  (“MEM”)  requested  that  the  Company 
prepare  and  present  to  MEM  a  reclamation  plan  for  closure  and  abandonment  of  certain  mining  claims  in  British 
Columbia which the Company had disposed of in 1996.  A plan was presented to MEM and we are awaiting a formal 
response. Assuming no other potentially responsible parties are identified, we have accrued estimated reclamation and 
other  related  costs,  as  of  December  31,  2018  and  2017  on  an  undiscounted  basis,  which  have  been  included  in 
exploration, property evaluation and holding costs.

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.
