This Annual Report on Form 10-K contains statements that constitute "forward-looking statements" within the 
meaning of section 27A of the Securities Act of 1933 and section 21E of the Securities Exchange Act of 1934, as amended (the 
“Exchange Act”). These statements can be identified by the fact that they do not relate strictly to historical information and 
include the words "expects", "believes", "anticipates", "plans", "may", "will", "intend", "estimate", "continue" or other similar 
expressions. These forward-looking statements are subject to various risks and uncertainties that could cause actual results to 
differ materially from those currently anticipated.  These risks and uncertainties include, but are not limited to, items discussed 
below in Item 1A "Risk Factors" in this Form 10-K. Forward-looking statements speak only as of the date made.  We undertake 
no obligation to publicly release or update forward-looking statements, whether as a result of new information, future events or 
otherwise. You are, however, advised to consult any further disclosures we make on related subjects in our quarterly reports on 
Form 10-Q and any reports made on Form 8-K to the United States Securities and Exchange Commission (the "SEC").   

Item 1. Business 

The Company 

Solitario Zinc Corp (“Solitario,” “Company,” “we,” “us”) is an exploration stage company at December 31, 2017 

under Industry Guide 7, as issued by the SEC.  Solitario was incorporated in the state of Colorado on November 15, 1984 as a 
wholly-owned subsidiary of Crown Resources Corporation ("Crown").  In July 1994, Solitario became a publicly traded 
company on the Toronto Stock Exchange (the “TSX”) through its initial public offering.  We have been actively involved in 
mineral exploration since 1993.  Our primary business is to acquire exploration mineral properties or royalties on mineral 
properties, and/or to discover economic deposits on our mineral properties and advance these deposits, either on our own or 
through joint ventures, up to the development stage (development activities include, among other things, completion of a 
feasibility study for the identification of proven and probable reserves, as well as permitting and preparing a deposit for 
mining).  Upon the completion of the Acquisition (defined below), we have shifted our primary focus toward the acquisition 
and exploration of zinc-related exploration mineral properties.  However, we will continue to evaluate other mineral properties 
for acquisition and hold a portfolio of mineral exploration properties and assets for future sale, joint venture or to create a 
royalty prior to the definition of proven and probable reserves.  We may attempt to sell a given mineral property, pursue its 
development either on our own or through a joint venture with a partner that has expertise in mining operations, or obtain a 
royalty from a third party that continues to advance the property.  In addition to focusing on our current assets and the 
evaluation of mineral properties for the acquisition of royalty interests, we also evaluate potential strategic corporate 
transactions that could result in Solitario obtaining an interest in precious and base metal properties with exploration potential 
or other business combinations we determine to be favorable to Solitario.   

Recent Developments 

Acquisition of Zazu 

On July 12, 2017 Solitario  completed the acquisition of Zazu Metals Corp. (“Zazu”) pursuant to a definitive 
arrangement agreement (the “Arrangement Agreement”) whereby we acquired all of the outstanding common shares of Zazu 
(the “Zazu Shares”) by way of a statutory plan of arrangement (the “Arrangement”) under the Canada business Corporation 
Act (the “Acquisition”).  As a result of the Acquisition, Zazu became a wholly-owned subsidiary of Solitario.  At closing, we 
issued 19,788,177 shares of common stock for all of the issued and outstanding Zazu Shares.  We also granted options to 
acquire an aggregate of 1,782,428 shares of Solitario common stock (the “Replacement Options”) in connection with the 
Acquisition.  The total purchase price for the Acquisition was $16,110,000 and has been allocated to the assets acquired and 
stock issuance costs, less liabilities.  Results of operations for Zazu have been included in our consolidated financial statements 
from the date of Acquisition. 

Name Change to Solitario Zinc Corp. 

Our shareholders voted at our annual meeting of shareholders held on June 29, 2017 in favor of an amendment to 

Solitario’s Articles of Incorporation to change our name to “Solitario Zinc Corp.” from “Solitario Exploration & Royalty 
Corp.”  The name change was subject to the completion of the Acquisition and became effective on July 17, 2017.

Mineral Exploration Properties 

As a result of the Acquisition, at December 31, 2017 we hold a 50% operating interest in the Lik zinc-lead-silver 

deposit in Northwest Alaska, which is considered a large tonnage, high-grade and mineable by open-pit methods.  Teck 
Resources Limited (“Teck”) is a 50% partner with Solitario in the Lik deposit, with Solitario acting as the project manager.  
Zazu completed a Canadian National Instrument 43-101 compliant Preliminary Economic Assessment (“PEA”) on the Lik 
deposit in 2014. 

Solitario’s other core asset is a 39% interest in the advanced, high-grade, Florida Canyon zinc project located in 

northern Peru.  The project has a significant mineral resource and Solitario is fully carried to production by its joint venture 
partner Nexa Resources, SA (“Nexa”) a Brazilian company, formerly Votorantim Metais Holdings, SA (“Votorantim”).  
Solitario and Nexa completed a PEA on the Florida Canyon deposit in August 2017.  Nexa is one of the largest zinc producers 
in Peru.  Since inception of the Florida Canyon joint venture in 2006, Nexa, as Votorantim and its subsidiary, Minera Milpo, 
have funded 100% of project expenditures.  Nexa will earn a 70% interest in the project by continuing to solely fund all project 
expenditures and committing to place the project into production based upon a positive feasibility study.   After earning 70%, 
and at the request of Solitario, Nexa has further agreed to finance Solitario's 30% participating interest for construction.  
Solitario will repay the loan facility through 50% of its net cash flow distributions.  

Solitario also holds an 85% interest in the Chambara exploration project in Peru (Nexa holds the remaining 15%), and 

a 9.9% equity interest in Vendetta Mining Corp. (“Vendetta”).   

At December 31, 2017, we also had the 100% owned La Promesa exploration property and our Yanacocha royalty 

property in Peru, a retained royalty on the Pedra Branca project in Brazil, a retained royalty on non-producing exploration 
properties in Mexico, and a royalty on certain non-producing mineral claims in Montana. We are conducting exploration and 
property evaluation activities in Peru either on our own using contract geologists, or through joint ventures operated by our 
partners.   

Our exploration activities and those of our joint venture partners are carried out on a property-by-property basis.  

These activities may include prospecting, geologic mapping, sampling, geophysics and drilling. When we determine that this 
work indicates a project may not be economic or contain sufficient geologic or economic potential, we may impair or 
completely write-off the property.  A significant factor in the success or failure of our activities is the price of commodities.  
For example, when the price of zinc or other commodities is down, we may determine that the value of our mineral exploration 
properties decreases; however, during such down markets it may also become easier and less expensive to locate and acquire 
new mineral exploration properties.    

We have recorded revenue in the past from the sale of mineral properties, joint venture property payments and the sale 

of a royalty on our formerly-held Mt. Hamilton property.  Proceeds from the sale or joint venture of properties, although 
potentially significant when they occur, have not been a consistent source of cash and may only occur in the future, if at all, on 
an infrequent basis.  Accordingly, while we conduct exploration activities on our projects, we need to maintain and replenish 
our capital resources.  We have met our need for capital in the past through (i) proceeds of the sale of our former Mt. Hamilton 
project in 2015 for net proceeds of $24 million (the “Mt. Hamilton Transaction”); (ii) sale of our shares of common stock of 
Vendetta  and Kinross Gold Corporation (“Kinross”); (iii) borrowing in the form of short-term margin debt secured by our 
investment in Kinross; (iv) borrowing under long-term debt secured by our Mt. Hamilton project (v) joint venture delay rental 
payments, including payments on our Florida Canyon project; (vi) a royalty sale for $10,000,000 in 2012; (vii) issuances of 
common stock; (viii) sale of covered call options on our Kinross common stock; and (ix) interest on short term Treasury Notes 
and Bank CDs.   In the past, we have reduced our exposure to the costs of our exploration activities through the use of joint 
ventures.   

We operate in one segment: mineral exploration.  We currently conduct exploration activities in Peru and Alaska and 

evaluate properties for potential acquisition and evaluation of strategic corporate opportunities throughout North and South 

4 

 
 
 
 
 
 
 
 
 
 
America.  As of March, 12, 2018, we had five full-time employees located in the United States and no full-time employees 
outside of the United States. We utilize contract managers, geologists, administrators and laborers to execute our Latin 
American project work and acquisition evaluations.  

A large number of companies are engaged in the acquisition, exploration and development of mineral properties, many 

of which have substantially greater technical and financial resources than we have and, accordingly, we may be at a 
disadvantage in being able to compete effectively for the acquisition, exploration and development of mineral properties.  We 
are not aware of any single competitor or group of competitors that dominate the exploration and development of mineral 
properties.  In acquiring mineral properties for exploration and development, we rely on the experience, technical expertise and 
knowledge of our employees and advisors, which is limited by the size of our company compared to many of our competitors 
who may have either more employees or employees with more specialized knowledge and experience. 

Governmental Regulations  

Mineral development and exploration activities are subject to various national, state/provincial, and local laws and 

regulations, 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.  Similarly, if any of our 
properties are developed and/or mined those activities are also subject to significant governmental regulation and oversight. We 
are required to obtain the licenses, permits and other authorizations in order to conduct our exploration programs.  

Environmental Regulations 

Our current and planned activities are subject to various national and local laws and regulations governing protection 

of the environment. These laws are continually changing and, in general, are becoming more restrictive. We are required to 
conduct our operations in compliance with applicable laws and regulations.  Changes to current local, state or federal laws and 
regulations in each jurisdiction in which we conduct our exploration activities could, in the future, require additional capital 
expenditures and increased operating and/or reclamation costs. Although we are unable to predict what additional legislation, if 
any, might be proposed or enacted, additional regulatory requirements could impact the economics of our projects.  During 
2017, we had no material environmental incidents or non-compliance with any applicable environmental regulations. 

Financial Information about Geographic Areas 

Included in the consolidated balance sheets at December 31, 2017 and 2016, are total assets of $73,000 and $60,000, 

respectively, related to Solitario's operations located outside of the United States.

Item 1A.  Risk Factors  

In addition to considering the other information in this Form 10-K, you should consider carefully the following factors.  

The risks described below are the significant risks we face and include all material risks.  Additional risks not presently known 
to us or risks that we currently consider immaterial may also adversely affect our business.  

Our mineral exploration activities involve a high degree of risk, and a significant portion of our business model envisions 
the sale or joint venture of mineral properties.  If we are unable to sell or joint venture these properties, the money spent on 
exploration may never be recovered and we could incur an impairment of our investments in our projects.

The exploration for mineral deposits involves significant financial and other risks over an extended period of time. 

Few properties that are explored are ultimately developed into producing mines. Major expenditures are required to determine 
if any of our mineral properties may have the potential to be commercially viable and be salable or joint ventured. Prior to 
completion of the feasibility study on our former Mt. Hamilton project, we had never established reserves on any of our 
properties. Significant additional expense and risks, including drilling and determining the feasibility of a project, are required 
prior to the establishment of reserves. It is impossible to ensure that the current or proposed exploration programs on properties 
in which we have an interest will be commercially viable or that we will be able to sell, joint venture or develop our properties. 
Whether a mineral deposit will be commercially viable depends on a number of factors, some of which are the particular 
attributes of the deposit, such as its size and grade, costs and efficiency of the recovery methods that can be employed, 
proximity to infrastructure, commodity prices, financing costs and governmental regulations, including regulations relating to 
prices, taxes, royalties, infrastructure, land use, importing and exporting of mineral products and environmental protection. 

We believe the data obtained from our own exploration activities or our partners' activities to be reliable; however, the 

nature of exploration of mineral properties and analysis of geological information is often subjective and data and conclusions 
are subject to uncertainty. Even if exploration activities determine that a project is commercially viable, it is impossible to 
ensure that such determination will result in a profitable sale of the project or development either on our own or by a joint 
venture in the future and that such project will result in profitable commercial mining operations. If we determine that 
capitalized costs associated with any of our mineral interests are not likely to be recovered, we would incur an impairment of 
our investment in such property interest. All of these factors may result in losses in relation to amounts spent, which are not 
recoverable. We have experienced losses of this type from time to time including during 2016 when we wrote down our 
investments in our exploration projects in Mexico and abandoned our Canta Colorado project in Peru, recording mineral 
property impairments totaling $13,000.  

We have no reported mineral reserves and none of our current projects are likely to be monetized in the near future and any 
projects we may acquire are not likely to offer the opportunity for near term revenues or sale proceeds, and if we are 
unsuccessful in identifying mineral reserves in the future, we may not be able to realize any profit from these property 
interests.  

None of our current projects have reported mineral reserves. Any mineral reserves on these projects will only come 

from extensive additional exploration, engineering and evaluation of existing or future mineral properties. The lack of reserves 
on these mineral properties could prohibit us from any near-term sale or joint venture of our mineral properties and we would 
not be able to realize any proceeds and or profit from our interests in such mineral properties, which could materially adversely 
affect our financial position or results of operations. 

We may not realize the benefits from the Acquisition because of various challenges.   

The Acquisition has, and will continue to involve the integration of companies that previously operated independently.  

Solitario’s ability to realize the anticipated benefits of the Acquisition will depend, in part, upon the following: 

• 
• 
• 
• 

the ability of Solitario to successfully integrate Zazu’s business and processes with those of Solitario; 
how efficiently Solitario’s officers can manage the operations of the combined company; 
the amount of charges associated with the Acquisition; and 
economic conditions affecting both the general economy and the mining industry in particular. 

Some of these factors are also outside of the control of Solitario. One or more of these factors could result in increased operating 
costs, lower earnings or losses or negative cash flows, any of which could reduce the market price of Solitario’s common stock. 

Further, achieving the benefits of the Arrangement, including the ability of Solitario to realize any profit from its 

investment in its interest in the Lik project will depend, among other things, upon meeting the challenges inherent in the 
successful combination of business enterprises of the size and scope of Solitario and Zazu and the possible resulting diversion of 
management attention for an extended period of time. There can be no assurance that the combined company will meet these 
challenges and that such diversion will not negatively impact the operations of the combined company following the closing of 
the Arrangement. 

The value of Solitario’s common stock may be adversely affected by any inability of the combined company to achieve the 
benefits expected to result from the completion of the Arrangement.

challenges and that such diversion will not negatively impact the operations of the combined company following the closing of 
the Arrangement. 

Mineral exploration activities are inherently dangerous and could cause us to incur significant unexpected costs, including 
legal liability for loss of life, damage to property and environmental damage, any of which could materially adversely affect 
our financial position or results of operations.  

Mining exploration operations are subject to the hazards and risks normally related to exploration of a mineral deposit, 

including mapping and sampling, drilling, road building, trenching, assaying and analyzing rock samples, transportation over 
primitive roads or via small contract aircraft or helicopters and severe weather conditions, any of which could result in damage 
to life or property, environmental damage and possible legal liability for such damage. Any of these risks could cause us to incur 
significant unexpected costs that could have a material adverse effect on our financial condition and ability to finance our 
exploration and development activities. 

We have a history of losses and if we do not operate profitably in the future it could have a material adverse effect on our 
financial position or results of operations and the trading price of our common stock would likely decline.  

We have reported losses in 21 of our 24 years of operations. We can provide no assurance that we will be able to 

operate profitably in the future or begin to generate significant and consistent sources of revenues or cash flows from 
operations. We have had net income in only three years in our history; during 2015, as a result of the Mt. Hamilton Transaction, 
during 2003, as a result of a $5,438,000 gain on a derivative instrument related to our investment in certain Crown warrants and 
during 2000, when we sold our former Yanacocha property. We cannot predict when, if ever, we will be profitable again or able 
to begin generating consistent revenues or cash flows from our operations or assets. If we do not operate profitably or identify 
and execute on outside sources of funding, we may be unable to fund our current or contemplated exploration activities, acquire 
new assets, or otherwise further our business plan.  

Our operations outside of the United States of America may be adversely affected by factors outside of our control, such as 
changing political, local and economic conditions, any of which could materially adversely affect our financial position or 
results of operations.  

Our mineral properties located in Latin America consist primarily of mineral concessions granted by national 

governmental agencies and are held 100% by us or in conjunction with our joint venture partners, or under lease, option or 
purchase agreements. Certain of our mineral properties are located in Peru and we hold royalties on non-producing exploration 
properties in Peru, Mexico, Brazil and Montana (U.S.). We act as operator on all of our mineral properties that are not held in 
joint ventures or royalty properties. The success of projects held under joint ventures or royalty properties that are not operated 
by us is substantially dependent on the joint venture partner, over which we have limited or no control. 

Our exploration activities, mineral properties and royalties located outside of the United States are subject to the laws 

of Peru, Mexico and Brazil and any other countries in which we conduct business. Exploration and potential development 
activities in these countries are potentially subject to political and economic risks, including: 

•        cancellation or renegotiation of contracts;  
•        disadvantages of competing against companies from countries that are not subject to US laws and regulations, 

including the Foreign Corrupt Practices Act; 

•        changes in foreign laws or regulations; 
•        changes in tax laws; 
•        royalty and tax increases or claims by governmental entities, including retroactive claims; 
•        expropriation or nationalization of property; 
•        currency fluctuations (particularly related to declines in the US dollar compared to local currencies); 
•        foreign exchange controls; 
•        restrictions on the ability for us to hold US dollars or other foreign currencies in offshore bank accounts; 
•        import and export regulations; 
•        environmental controls;  

7 

 
 
 
 
 
 
 
 
 
•        risks of loss due to community opposition to our activities, civil strife, acts of war, guerrilla activities, 

insurrection and terrorism; and 

•        other risks arising out of foreign sovereignty over the areas in which our exploration activities  

are conducted. 

Accordingly, our current exploration activities outside of the United States may be substantially affected by factors 
beyond our control, any of which could materially adversely affect the value of certain of our assets or results of operations. 
Furthermore, in the event of a dispute arising from such activities, we would likely be subject to the exclusive jurisdiction of 
courts outside of the United States or may not be successful in subjecting persons to the jurisdictions of the courts in the United 
States, which could adversely affect the outcome of a dispute. 

We may not have sufficient funding for exploration and development, which may impair our profitability and growth.  

The capital required for exploration and development of mineral properties is substantial. In the past we have financed 
operations through the sale of interests in mineral properties, including the Mt. Hamilton Transaction in 2015, the utilization of 
joint venture arrangements with third parties (generally providing that the third party will obtain a specified percentage of our 
interest in a certain property or a subsidiary owning a property in exchange for the expenditure of a specified amount), the sale 
of other assets, sale of marketable equity securities we hold, short-term margin loans, funds from the long-term debt, and the 
issuance of common stock.  We may need to raise additional capital, or enter into joint venture arrangements, in order to fund 
the exploration activities required to determine whether mineral deposits on our projects are commercially viable. New 
financing or acceptable joint venture partners may or may not be available on a basis that is acceptable to us. The inability to 
obtain new financing or joint venture partners on acceptable terms may prohibit us from continued development or exploration 
of our mineral properties. Without the successful sale or future development of our mineral properties through joint ventures, or 
on our own, we will not be able to realize any profit from our interests in such properties, which could have a material adverse 
effect on our financial position and results of operations. 

A large number of companies are engaged in the exploration and development or sale of mineral properties, many of which 
have substantially greater technical and financial resources than us and, accordingly, we may be unable to compete 
effectively in this sector of the mining industry which could have a material adverse effect on our financial position or 
results of operations.  

We are at a disadvantage with respect to many of our competitors in the acquisition, exploration and development or 

sale of mining projects. Our competitors with greater financial resources than us will be better able to withstand the 
uncertainties and fluctuations associated with sustained downturns in the market and to acquire high quality exploration and 
mining properties when market conditions are favorable.  In addition, we compete with other companies in the mineral 
properties sector to attract and retain key executives and other employees with technical skills and experience in the mineral 
exploration business. There can be no assurance that we will continue to attract and retain skilled and experienced employees or 
to acquire additional exploration projects. The realization of any of these risks from competitors could have a material adverse 
effect on our financial position or results of operations.  

The title to our mineral properties may be defective or challenged which could have a material adverse effect on our 
financial position or results of operations. 

In connection with the acquisition of our mineral properties, we conduct limited reviews of title and related matters, 

and obtain certain representations regarding ownership. These limited reviews and representations do not necessarily preclude 
third parties from challenging our title and, furthermore, our title may be defective. Consequently, there can be no assurance 
that we hold good and marketable title to all of our mineral interests. Additionally, we have to make annual filings to various 
government agencies on all of our mineral properties.  If we fail to make such filings, or improperly document such filings, the 
validity of our title to a mineral property could be lost or challenged.  If any of our mineral interests were challenged, we could 
incur significant costs in defending such a challenge. These costs or an adverse ruling with regards to any challenge of our titles 
could have a material adverse effect on our financial position or results of operations. 

Our operations could be negatively affected by existing laws as well as potential changes in laws and regulatory 
requirements to which we are subject, including regulation of mineral exploration and ownership, environmental 
regulations and taxation.  

The exploration and development of mineral properties is subject to federal, state, provincial and local laws and 
regulations in the countries in which we operate in a variety of ways, including regulation of mineral exploration and land 
ownership, environmental regulation and taxation. These laws and regulations, as well as future interpretation of or changes to 
8 

 
 
 
 
 
 
 
 
 
 
existing laws and regulations, may require substantial increases in capital and operating costs to us and delays, interruptions, or 
a termination of operations. 

In the United States and the other countries in which we operate, in order to obtain permits for exploration or potential 

future development of mineral properties, environmental regulations generally require a description of the existing 
environment, including but not limited to natural, archeological and socio-economic environments, at the project site and in the 
region; an interpretation of the nature and magnitude of potential environmental impacts that might result from such activities; 
and a description and evaluation of the effectiveness of the operational measures planned to mitigate the environmental 
impacts. Currently the expenditures to obtain exploration permits to conduct our exploration activities are not material to our 
total exploration cost. 

The laws and regulations in all the countries in which we operate are continually changing and are generally becoming 

more restrictive, especially environmental laws and regulations. As part of our ongoing exploration activities, we have made 
expenditures to comply with such laws and regulations, but such expenditures could substantially increase our costs to achieve 
compliance in the future. Delays in obtaining or failure to obtain government permits and approvals or significant changes in 
regulation could have a material adverse effect on our exploration activities, our ability to locate economic mineral deposits, 
and our potential to sell, joint venture or eventually develop our properties, which could have a material adverse effect on our 
financial position or results of operations. 

Occurrence of events for which we are not insured may materially adversely affect our business. 

Mineral exploration is subject to risks of human injury, environmental liability and loss of assets. We maintain limited 
insurance coverage to protect ourselves against certain risks related to loss of assets for equipment in our operations and limited 
corporate liability coverage; however, we have elected not to have insurance for other risks because of the high premiums 
associated with insuring those risks or for various other reasons including those risks where insurance may not be available. 
There are additional risks in connection with investments in parts of the world where civil unrest, war, nationalist movements, 
political violence or economic crisis are possible. These countries may also pose heightened risks of expropriation of assets, 
business interruption, increased taxation and a unilateral modification of concessions and contracts. We do not maintain 
insurance against political risk. Occurrence of events for which we are not insured could have a material adverse effect on our 
financial position or results of operations. 

Severe weather or violent storms could materially affect our operations due to damage or delays caused by such weather.  

Our exploration activities are subject to normal seasonal weather conditions that often hamper and may temporarily 
prevent exploration or development activities. There is a risk that unexpectedly harsh weather or violent storms could affect 
areas where we conduct these activities. Delays or damage caused by severe weather could materially affect our operations or 
our financial position. 

Our business is dependent on the market price of commodities and currency exchange rates over which we have no control.  

Our operations are significantly affected by changes in the market price of commodities since the evaluation of 
whether a mineral deposit is commercially viable is heavily dependent upon the market price of the commodities related to any 
specific project, such as gold or zinc. The price of commodities also affects the value of exploration projects we own or may 
wish to acquire or joint venture. These commodity prices fluctuate on a daily basis and are affected by numerous factors beyond 
our control. The supply and demand for commodities, the level of interest rates, the rate of inflation, investment decisions by 
large holders of these commodities, including governmental reserves, and stability of exchange rates can all cause significant 
fluctuations in prices. Currency exchange rates relative to the United States dollar can affect the cost of doing business in a 
foreign country in United States dollar terms, which is our functional currency. Consequently, the cost of conducting 
exploration in the countries where we operate, accounted for in United States dollars, can fluctuate based upon changes in 
currency exchange rates and may be higher than we anticipate in terms of United States dollars because of a decrease in the 
relative strength of the United States dollar to currencies of the countries where we operate. We currently do not hedge against 
currency or commodity fluctuations. The prices of commodities as well as currency exchange rates have fluctuated widely and 
future significant price declines in commodities or changes in currency exchange rates could have a material adverse effect on 
our financial position or results of operations. 

Our business is dependent on key executives and the loss of any of our key executives could adversely affect our business, 
future operations and financial condition.  

9 

 
 
 
 
 
 
 
 
 
 
 
We are dependent on the services of key executives, including our Chief Executive Officer, Christopher E. Herald, our 
Chief Operating Officer, Walter H. Hunt, and our Chief Financial Officer, James R. Maronick. All of those officers have many 
years of experience and an extensive background with Solitario and in the mining industry in general. We may not be able to 
replace that experience and knowledge with other individuals. We do not have "Key-Man" life insurance policies on any of our 
key executives. The loss of these persons or our inability to attract and retain additional highly skilled employees may adversely 
affect our business, future operations and financial condition. 

Our business model relies significantly on other companies to joint venture our projects and we anticipate continuing this 
practice in the future. Therefore, our results are subject to the additional risks associated with the financial condition, 
operational expertise and corporate priorities of our joint venture partners.  

Our Florida Canyon project is joint-ventured with another mining company that manages the exploration and 

development activities on the project and we are the minority-interest party.  Although our joint venture agreement provides 
certain voting rights and other minority-interest safeguards, the majority partner not only manages operations, but controls most 
decisions, including budgets and scope and pace of exploration and development activities.  Consequently, we are highly 
dependent on the operational expertise and financial condition of our joint venture partner, as well as its own corporate 
priorities.  For instance, even though our joint venture property may be highly prospective for exploration success, or 
economically viable based on feasibility studies, our partner may decide to not fund the further exploration or development of 
our project based on their respective financial condition or other corporate priorities.  Therefore, our results are subject to the 
additional risks associated with the financial condition, operational expertise and corporate priorities of our joint venture 
partners, which could have a material adverse effect on our financial position or results of operations.  Our Lik project is 
equally owned with another mining company and unanimous consent by the joint venture partners is required for annual 
budgets in excess of $1.0 million.  Consequently, development of the project could be delayed without unanimous consent. 

We may look to joint venture with another mining company in the future to develop and/or operate one of our foreign 
projects; therefore, in the future, our results may become subject to additional risks associated with development and 
production of our foreign mining projects.  

We are not currently involved in mining development or operation at any of our properties. In order to realize a profit 
from our mineral interests we either have to: (1) sell such properties outright at a profit; (2) form a joint venture for the project 
with a larger mining company with greater resources, both technical and financial, to further develop and/or operate a project at 
a profit; (3) develop and operate such projects at a profit on our own; or (4) create and retain a royalty interest in a property 
with a third party that agrees to advance the property toward development and mining. In the future, if our exploration results 
show sufficient promise in one of our foreign projects, we may either look to form a joint venture with another mining company 
to develop and/or operate our projects, or sell the property outright and retain partial ownership or a retained royalty based on 
the success of such project. Therefore, in the future, our results may become subject to the additional risks associated with 
development and production of mining projects in general. 

In the future, we may participate in a transaction to acquire a new property, royalty or another company that requires a 
substantial amount of capital or the issuance of Solitario equity to complete. Acquisition costs may never be recovered due to 
changing market conditions, or our own miscalculation concerning the recoverability of our acquisition investment. Such 
an occurrence could adversely affect our business, future operations and financial condition.  

We have evaluated a wide variety of acquisition opportunities involving mineral properties and companies for 

acquisition and we anticipate evaluating potential acquisition opportunities in the future. Some of these opportunities may 
involve a substantial amount of capital or the issuance of Solitario equity to successfully acquire. As many of these 
opportunities do not have reliable feasibility-level studies, we may have to rely on our own estimates for investment analysis. 
Such estimates, by their very nature, contain substantial uncertainty. In addition, economic assumptions, such as future costs 
and commodity prices, also contain significant uncertainty. Consequently, if we are successful in acquiring any new 
opportunities and our estimates prove to be in error, either through miscalculations or changing market conditions, this could 
have a material adverse effect on our financial position or results of operations. 

The market for shares of our common stock has limited liquidity and the market price of our common stock has fluctuated 
and may decline.  

An investment in our common stock involves a high degree of risk. The liquidity of our shares, or the ability of a 
shareholder to buy or sell our common stock, may be significantly limited for various unforeseeable periods. The average 
combined daily volume of our shares traded on the NYSE American and the TSX during 2017 was approximately 114,000 
shares. The market price of our shares has historically fluctuated within a wide range. The price of our common stock may be 
10 

 
 
 
 
 
 
 
 
 
affected by many factors, including an adverse change in our business, a decline in the price of zinc or other commodity prices, 
negative news on our projects, negative investment sentiment for mining and commodity equities and general economic trends. 

A significant portion of our liquid assets consist of U.S. Treasuries and bank certificates of deposit.  The failure of the 
financial institutions that issued or hold these financial instruments could have a material adverse impact on the market 
price of our common stock and our liquidity and capital resources. 

At December 31, 2017, we have invested approximately $1,247,000 in separate, FDIC insured certificates of deposit 
with the maximum individual bank exposure of $250,000.  Further, as of December 31, 2017 we have invested $10,395,000 in 
United States Treasury securities, with maturities of between 15 days and 19 months and we have approximately $156,000 of 
our cash in uninsured deposit accounts including $105,000 held in brokerage accounts, none of which are covered by FDIC 
insurance.  The failure of either Charles Schwab or the financial institutions holding these funds and assets could have a 
material impact on the market price of our common stock and our liquidity and capital resources. 

We are dependent upon information technology systems, which are subject to disruption, damage, failure and risks 
associated with implementation and integration.  

We are dependent upon information technology systems in the conduct of our operations. Our information technology 

systems are subject to disruption, damage or failure from a variety of sources, including, without limitation, computer viruses, 
security breaches, cyber-attacks, natural disasters and defects in design. Cybersecurity incidents, in particular, are evolving and 
include, but are not limited to, malicious software, attempts to gain unauthorized access to data and other electronic security 
breaches that could lead to disruptions in systems, unauthorized release of confidential or otherwise protected information and 
the corruption of data. Various measures have been implemented to manage our risks related to information technology systems 
and network disruptions. However, given the unpredictability of the timing, nature and scope of information technology 
disruptions, we could potentially be subject to operational delays, the compromising of confidential or otherwise protected 
information, destruction or corruption of data, security breaches, other manipulation or improper use of our systems and 
networks or financial losses from remedial actions, any of which could have a material adverse effect on our cash flows, 
competitive position, financial condition or results of operations.  

Failure to comply with the United States Foreign Corrupt Practices Act (“FCPA”) could subject us to penalties and other 
adverse consequences.  

As a Colorado corporation, we are subject to the FCPA and similar worldwide anti-bribery laws, which generally 
prohibit United States companies and their intermediaries from engaging in bribery or other improper payments to foreign 
officials for the purpose of obtaining or retaining business. Foreign companies, including some that may compete with our 
company, are not subject to U.S. laws and regulations, including the FCPA, and therefore our exploration, development, 
production and mine closure activities are subject to the disadvantage of competing against companies from countries that are 
not subject to these prohibitions. 

In addition, we could be adversely affected by violations of the FCPA and similar anti-bribery laws in other 
jurisdictions. Corruption, extortion, bribery, pay-offs, theft and other fraudulent practices may occur from time-to-time in the 
countries outside of the United States in which we operate. Our mineral properties are located in countries that may have 
experienced governmental corruption to some degree and, in certain circumstances, strict compliance with anti-bribery laws 
may conflict with local customs and practices. Our policies mandate compliance with these anti-bribery laws; however, we 
cannot assure you that our internal controls and procedures always will protect us from the reckless or criminal acts committed 
by our employees or agents. We can make no assurance that our employees or other agents will not engage in such conduct for 
which we might be held responsible. If our employees or other agents are found to have engaged in such practices or we are 
found to be liable for FCPA violations, we could suffer severe criminal or civil penalties or other sanctions and other 
consequences that may have a material adverse effect on our business, financial condition and results of operations. 

Recently enacted changes in tax law could materially affect our financial position and results of operations. 

On December 22, 2017, the President of the United States signed into law H.R. 1 (the “U.S. Tax Reform”). We are in 

the process of determining the impact to our financial statements of all aspects of U.S. Tax Reform and intend to reflect the 
impact of such reform in the financial statements during the period in which such amounts can be reasonably estimated. The 
U.S. Tax Reform includes a number of provisions, including the lowering of the U.S. corporate tax rate from 35% to 21%, 
effective January 1, 2018. There are also provisions that may partially offset the benefit of such rate reduction, such as the 
repeal of the deduction for domestic production activities. The U.S. Tax Reform also includes international provisions, which 
generally establish a territorial- style system for taxing foreign-source income of domestic multinational corporations. Financial 
11 

 
 
 
 
   
 
 
 
 
 
 
 
statement impacts could include adjustments for the measurement of deferred tax assets (liabilities) and the accrual for deemed 
repatriation tax on unremitted foreign earnings and profits. There is substantial uncertainty regarding the details of the U.S. Tax 
Reform. The intended and unintended consequences of the U.S. Tax Reform on our business are not yet widely understood and, 
due to our international business activities, the changes to the taxation of our activities affected by the U.S. Tax Reform could 
increase our worldwide effective tax rate and could materially impact our financial position or results of operations.

Florida Canyon Zinc Project (Peru)  

1.  Property Description and Location  

(Map of Florida Canyon Property) Florida Canyon.jpg 

  On August 15, 2006, Solitario signed a Letter Agreement with Votorantim Metais Cajamarquilla, S.A., a wholly-

owned subsidiary of Votorantim (now known as Nexa) both companies are referred to in this Item 2 as "Nexa”) on Solitario's 
100%-owned Florida Canyon zinc project (formerly called the Bongará project),  On March 24, 2007, Solitario signed the 
Framework Agreement with Votorantim for the Exploration and Potential Development of Mining Properties, pursuant to, and 
replacing, the Florida Canyon Letter Agreement.  In 2015 Votorantim transferred its interest in the Florida Canyon project to 
Compañía Minera Milpo S.A.A. (“Milpo”), an 80%-owned affiliate of Votorantim.  In October of 2017, Milpo and Votorantim 
merged to form Nexa.  Nexa completed an IPO raising $570 million and listed on the NYSE under the trading symbol NEXA 
and the TSX under the trading symbol NEXA.  For the remainder of this Florida Canyon property section, all references to 
Votorantim, Milpo or Nexa will be collectively referred to as Nexa.    

The Florida Canyon project consists of 16 concessions comprising 12,600 hectares of mineral rights originally granted 
to Minera Bongará S.A., our subsidiary incorporated in Peru.  The property is located in the Department of Amazonas, northern 
Peru.  Solitario's and Nexa’s property interests are held through the ownership of shares in Minera Bongará S.A., a joint 
operating company that holds a 100% interest in the mineral rights and other project assets.  Solitario currently owns 39% of the 
shares in Minera Florida Canyon S.A. 

During 2015 Nexa completed the steps required to earn a 61% interest in the Florida Canyon project, with Solitario 

retaining a 39% interest.    Nexa may earn an additional 9% interest (up to a 70% shareholding interest) in Minera Bongará 
S.A., by sole-funding future annual exploration and development expenditures until a production decision is made.  The option 
to earn the 70% interest can be exercised by Nexa at any time by committing to place the project into production based upon a 
completed feasibility study.  Nexa is the project manager.  Once Nexa has committed to place the project into production based 
upon a feasibility study, it has further agreed to finance Solitario's 30% participating interest until production with a loan 
facility from Nexa to Solitario.   Solitario will repay this loan facility through 50% of Solitario's cash flow distributions from 
the joint operating company. 

According to Peruvian law, concessions may be held indefinitely, subject only to payment of annual fees to the 

government.  In June 2018, payments of approximately $176,000to the Peruvian government will be due in order to maintain 
the Florida Canyon mineral rights of Minera Bongará.  Nexa is responsible for paying these costs as part of its earn-in 
expenditures.  Peru imposes a sliding scale royalty varying from 1% to 12% of the operating profit of a mining operation.    The 
percentage royalty is determined by rule based on the operating margin; however, the minimum royalty is 1% of the revenues.  

From time to time Nexa may enter into surface rights agreements with individual landowners or communities to 

provide access for exploration work.  Generally, these are short-term agreements.  

Environmental permits are required for exploration and development projects in Peru that involve drilling, road 

building or underground mining.  The requisite environmental and archeological studies were completed for all past work, but 
new studies are required for expanded activities planned for future years.  Although we believe that these permits will be 
obtained in a timely fashion, the timing of government approval of permits remains beyond our control.  

2.  Accessibility, Climate, Local Resources, Infrastructure and Physiology 

12 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
The Florida Canyon property is accessed from the coastal city of Chiclayo by the paved Carretera Marginal road, 
which is a heavily travelled paved national highway that passes approximately eight kilometers south of the deposit.  The 
nearest town to the project is Pedro Ruiz located 15 kilometers southeast of the property. The area of the majority of past 
drilling and the most prospective mineralization, Florida Canyon, was previously inaccessible by road, the work to date having 
been done by either foot or helicopter access.  Nexa has now completed approximately 30 kilometers of access road.  Nexa is 
planning to complete the road access to the mineralized area of the project in 2018.  Nexa maintains project field offices in 
Pedro Ruiz and a drill core processing facility and operations office in the nearby community of Shipasbamba.    

The project area elevation ranges between 1,800 and 3,200 meters above sea level.  The climate is tropical with an 

average annual temperature of approximately 25oC.  Mean annual rainfall exceeds one meter with up to two meters in the cloud 
forest at higher elevations.  Most precipitation occurs during the rainy season, between November and April.  Field work is 
considerably more difficult in the rainy season.  Topography is steep, consisting of prominent escarpments and deep valleys.  
Dense jungle or forest vegetation covers the project area,    With the exception of the partially completed access road and 
approximately 700 meters of tunneling, no infrastructure facilities have been constructed within the project area. 

3.  History 

We discovered the Florida Canyon mineralized zone of the Florida Canyon Project in 1996.  Subsequently, we joint 

ventured the property in December 1996 to Cominco (now Teck Resources).  Cominco drilled 80 core holes from 1997-2000.  
Cominco withdrew from the joint venture in February 2001, and Solitario retained its 100% interest in the project.  We 
maintained the claims from 2001 to 2006, until the Florida Canyon Letter Agreement was signed.  Nexa conducted surface 
drilling on an annual basis from 2006 to 2013 and underground tunneling and drilling from 2010 to 2013.  All significant work 
on the property has been conducted by our joint venture partners: Cominco and Nexa and is described below in Section 5, 
“Prior Exploration.” 

4. Geological Setting 

The project is located within an extensive belt of Mesozoic carbonate rocks belonging to the Upper Triassic to Lower 

Jurassic Pucará Group and equivalents. This belt extends through the central and eastern extent of the Peruvian Andes for 
nearly 1000 km and is the host for many polymetallic and base metal vein and replacement deposits in the Peruvian Mineral 
Belt.  Among these is the San Vicente Mississippi Valley Type (“MVT”) zinc-lead deposit that has many similarities to the 
Florida Canyon deposit and other MVT occurrences in the Project area.  

The geology of the Florida Canyon area is relatively simple consisting of a sequence of Jurassic and Triassic clastic 

and carbonate rocks which are gently deformed into a broad northwesterly trending domal anticline.  The MVT zinc-lead 
mineralization occurs in the carbonate facies of the Chambara (rock) Formation.  This domal anticline is cut on the west by the 
Sam Fault and to the east by the Tesoro-Florida Fault.   

5. Prior Exploration 

We conducted a regional stream sediment survey and reconnaissance geological surveys leading to the discovery of 
the Florida Canyon area in 1996.  The discovered outcropping mineralization is located in two deeply incised canyons within 
the limestone stratigraphy. 

Subsequent to our initial work, Cominco conducted extensive mapping, soil and rock sampling, stream sediment 

surveys and drilling.  This work was designed to determine the extent and grade of the zinc-lead mineralization, the controls of 
mineral deposition and to identify areas of potential new mineralization.  Nexa began work in the fall of 2006 and drilled 
annually from 2006 through 2013.   Underground exploration operations were conducted from 2011-2013.  Since 2013 the 
most important work conducted consisted of continued access road construction and metallurgical testing.  All work performed 
by us, Cominco, and Nexa was done by direct employees of the respective companies with the exception of the drilling, 
underground tunneling, helicopter services and road building, all of which were performed by third-party contractors under the 
direction of Cominco and Nexa. 

6. Mineralization 

Mineralization occurs as massive to semi-massive replacements of sphalerite and galena localized by specific 
sedimentary facies (rock strata) within the limestone stratigraphy and by structural feeders and karst breccias.  More than three-
quarters of mineralization is sulfide-dominant with the remainder being oxide-dominant.  A total of 11 preferred beds for 
replacement mineralization have been located within the middle unit of the Chambara Formation.  Mineralization is associated 
13 

 
 
 
 
 
 
 
 
 
 
 
 
with the conversion of limestone to dolomite, which creates porosity and permeability within the rock formations, promoting 
the passage of mineralizing fluids through the rock formations forming stratigraphically controlled near-horizontal manto 
deposits.  Drilling of stratigraphic targets has shown that certain coarser-grained facies of the stratigraphy are the best hosts for 
manto mineralization. Stratigraphically controlled mineralization is typically one to several meters in thickness, but often 
attains thicknesses of five to ten meters.   

The laterally extensive manto deposits are strongly related to, and potentially originate from, structurally controlled 
near-vertical conduits for mineralizing solutions.  Replacement deposits occur along these high-angle structures as well as in 
the stratigraphic mantos at Florida Canyon.  

Karst features are localized along the feeder faults and locally produce "breakout zones" where mineralization may 

extend vertically across thick stratigraphic intervals where collapse breccias have been replaced by ore minerals.  Mineralized 
karst structures are up to 50 meters in width (horizontal), up to 100 meters vertically, and up to hundreds of meters along strike.   

Evidence for these breakout zones is provided by the following drill holes from various locations on the property:

Dolomitization reaches stratigraphic thicknesses in excess of 100 meters locally.  This alteration is thought to be 

related to the mineralizing event and is an important exploration tool.  Continuity of the mineralization is demonstrable in areas 
of highest drilling density by correlation of mineralization within characteristic sedimentary facies, typical of specific 
stratigraphic intervals or within through-going observable structural zones in drill core.  At Florida Canyon the high-angle 
mineralization occurs along well-defined northwest and northeast fracture systems.  These structures occur in conjugate 
fractures, with N10º-50ºE trends present at a number of mineralized surface outcrops while trends of N50º-80ºW are identified 
at other showings.   

7. Drilling 

From 1997 through 2001, Cominco drilled 80 surface core holes totaling 24,696 meters.  From 2006-2013, Nexa 

completed 309 surface core holes totaling 77,193 meters.  From 2011-2013, Nexa completed 95 underground core holes 
totaling 15,144 meters.  The majority of Nexa’s surface drilling was infill drilling designed to demonstrate the continuity and 
geometry of mineralization, and to a lesser extent, test for extensions of known mineralization.  The underground drilling was 
conducted from 10 drill stations at generally 40-meter centers (two drill stations at 20-meter centers) and entirely within the 
San Jorge mineralized zone.  Anywhere from three to 14 holes were drilled from each of the ten drill stations.  The 
underground drilling was tightly spaced and designed to allow for feasibility-level reserve estimation.   

All drilling conducted is within a footprint measuring approximately 2.5 kilometers long in a north-south direction and 
a little over a kilometer in an east-west direction.  The entire drill pattern is within what we have informally labeled the Florida 
Canyon district.  Within this district, several zones of strong zinc mineralization have been defined.  The two zones with the 
largest amount of drilling are the San Jorge and the Karen-Milagros zones.  Drilling indicates that, for the most part, the entire 
Florida Canyon district remains open to expansion and the identified zones are interconnected.  Typical drill-hole intercepts are

8. Sampling, Analysis and Security of Samples 

Core samples were transported from the drill by helicopter in sealed boxes to the processing facility in Shipasbamba 
where they were cut with a diamond saw.  Half of the core was taken of intervals selected according to geologic criteria under 
the supervision of the geologist in charge and shipped in sealed bags by land.  Cominco used SGS Laboratories and Nexa used 
ALS-Chemex, both in Lima, Peru, where all samples were analyzed by ICP.  Any samples that contained greater than 1% zinc 
were then analyzed by wet chemistry assay for zinc and lead to provide a more accurate analysis of grade.  

Since 2006, Nexa has been in control of all field activities on the project and is responsible for the security of samples.  

Nexa has indicated that there have been no breaches in the security of the samples.  We have reviewed and engaged SRK 
Consulting (USA) Inc. (“SRK”) (a large independent international mining engineering firm) to review Nexa’s sampling 
procedures and believe that adequate procedures are in place to ensure the future security and integrity of samples.  No 
breaches of security of samples are known to have occurred prior to Nexa’s work on the project. 

9. Prefeasibility Studies 

Nexa, either through its engineering staff or contracted independent mining engineering firms, has conducted 
prefeasibility-level studies to provide estimates of deposit size and grade, mining and processing recoveries, sizing of 
appropriate scale of operations, infrastructure design, and capital and operating cost estimates at a level of detail varying from 
preliminary economic assessment to feasibility levels.  These studies were generally performed between 2007 and 2014.   

Solitario and Nexa jointly completed a PEA for the entire project in 2017 that incorporated a variety of Nexa-
generated studies into the analysis.  The PEA evaluation included resource estimation, mining and processing recovery 
estimates, a preliminary mining and processing plan, infrastructure layout, environmental considerations and an economic 
analysis based on certain base case parameters.  The PEA envisioned an underground mining operation with a 2,500 tonne per 
day floatation mill for processing, resulting in a 12.5 year mine life.  It was assumed that concentrates would be trucked to 
Nexa’s Cajamarquilla zinc smelter facility in Lima Peru. 

Metallurgical testing to evaluate metal recoveries and various processing options for mineralized material at Florida 
Canyon was conducted in 2010, 2011 and 2014.  Tests to date on composited samples indicate zinc recoveries of 91.8% and 
lead recoveries of 81.9% in the San Jorge zone and zinc recoveries of 80.3% and lead recoveries of 71.7% in the Karen-
Milagros zone.  These recoveries represent averages for each zone based on sulfide dominant mineralization, but oxide material 
was present in the tested samples.  Nexa also conducted a comprehensive geochemical testing program that demonstrated that 
zinc (and lead) recoveries were significantly affected by the Zn-sulfide/Zn-oxide ratio of mineralization.  In general, 
mineralized material with greater than an 80% ratio of Zn-sulfide/Zn-oxide, recoveries are greater than 90% for Zn.  
Conversely, for mineralized material, with less than a 20% ratio of Zn-sulfide/Zn-oxide, recoveries are approximately 40% for 
Zn.  Although sulfide recoveries achieved to date are very good, SRK suggests that optimization of processing and 
metallurgical parameters may result in improved recoveries and concentrate grade.  

Other prefeasibility work completed by Nexa included drilling 16 diamond core holes in 2013 to evaluate geotechnical 

and hydrological parameters of the mineralized areas for both engineering and environmental purposes.  In 2016, Nexa 
completed a geochemical/metallurgical study that more accurately defined the distribution of sulfide/oxide mineralization 
based on re-assaying of nearly all past drill-hole samples.  This information was critical in resource estimation and accurately 
estimating metal recoveries.  

The 2017 Florida Canyon Project PEA was completed by SRK on behalf of Nexa and Solitario in August of 2017.

Amazonas Department, Peru; Effective Date: July 13, 2017, Report Date: August 3, 2017;” can be found in the Company’s 
Canadian Sedar filings and is furnished in the Company’s U.S. Edgar filings.   

10. Reserves and Resources 

There are no reported mineral reserves. 

11. Mining Operations 

No commercial mining operations to recover metals have occurred on the project.  However, in September 2010 Nexa 

initiated an underground tunneling program to access mineralization and completed its underground work in 2013.  As of 
December 31, 2016, 700 meters of tunneling were completed.  

12. Planned Exploration and Development  

The planned 2018 work program includes: 1) the completion of the access road into the mineralized portion of the 

project area and, 2) permitting that will allow new underground tunneling, surface drilling and other activities associated with 
the future development of the project.  The terrain at Florida Canyon is steep and all previous project access supporting surface 
and underground work programs was conducted by helicopter or on foot.  The lack of road access restricted the scope of field 
activities to further advance the project.  With the completion of the road, heavy equipment will be able to enter the project area 
and allow feasibility related activities to proceed efficiently.  Important future activities that will be facilitated by the 
completion of the road are the construction of an underground tunnel into the Karen-Milagros high-grade zinc zone, detailed 
underground resource/reserve definition drilling, surface drilling designed to increase the project resources and additional 
feasibility-related studies.  Road work is scheduled to begin in May after the rainy season ends and continue until the road is 
completed.  

Lik Project (Alaska) 

1.  Property Description and Location 

(Map of Lik Property) Lik.jpg 

16 

 
  
  
 
 
 
 
 
 
 
 
 
 
 
 
The Lik property consists of 47 contiguous Alaska state mining claims . The contiguous claims have been grouped 

together for the purpose of working and operating under a common plan of development for the benefit of all of the claims. The 
claims cover an area of approximately 6,075 acres (2,460 ha). The claims are located in the southwestern DeLong Mountains in 
the Wulik River drainage.  

To retain the state claims, the Company is required to make annual rental payments to the State of Alaska.  The 
estimated rental payments for 2018 are $19,000. Property holders are also required to perform assessment work with the 
amount dependent on the area of the State claims.  Excess assessment expenditure credits may be carried forward for a 
maximum of four years. If required, payments may be made in lieu of work to allow retention of the property for a period of 
five consecutive years.  The geographical coordinates of the Lik deposit are approximately 163o 12’ W and 68o 10’ N. The 
figure above illustrates the location of the Lik property. 

2.  Acquisition History and Joint Venture Arrangement 

Solitario acquired its 50% interest in the Lik property from the acquisition of Zazu on July 12, 2017.  As a result of the 

Acquisition, Zazu became a wholly-owned subsidiary of Solitario.   Prior to that, Zazu acquired its 50% interest in the Lik 
property from GCO Minerals Company a wholly-owned subsidiary of the International Paper Company (“GCO”), on June 28, 
2007 by making a cash payment to GCO of $20,000,000 and granting GCO a 2% net proceeds interest. GCO also owns an 
additional 1% net profits interest in the Lik property from a 1997 agreement.   

The Company is participating in the exploration and possible development of the Lik property through a joint venture 

with Teck American, Inc. (“Teck American”), a wholly owned subsidiary of Teck Resources Limited as defined above, 
“Teck”).  The terms of the joint venture were governed by the Lik Block Agreement, made as of January 27, 1983, between 
Houston Oil & Minerals Exploration Company (“HOMEX”) and GCO (a wholly owned subsidiary of the International Paper 
Company).  HOMEX assigned its interest in the Lik Block Agreement to Echo Bay Mines Ltd., which, in turn, assigned such 
interest to Teck American.   

Under the terms of the Lik Block Agreement, GCO held a 50% interest, and the right to increase its interest to up to 

80% provided that GCO met an inflation-adjusted work commitment.  The required expenditure amount was originally $25 
million when defined in 1983 and increased with inflation indexing and escalations to approximately $43 million at the time 
Solitario closed the Acquisition.  As of January 27, 2018, we estimate approximately $22 million had been incurred towards the 
inflation adjusted $43 million expenditure required to earn an additional 30% interest in the property.   

17 

 
 
 
 
 
 
 
 
 
As the Company did not spend the full inflation-adjusted expenditure amount by January 27, 2018, the Lik Block 

Agreement terminated.  Consequently Teck American retains its 50% participating interest in the Lik property, and Teck 
American and Solitario will execute a joint operating agreement governing all further operations relating to the Lik property.  
Under such joint operating agreement, the Company, as successor to GCO, would be the operator and would have full and 
exclusive control of the Lik property, its facilities and production as well as the exploration, development and mining 
undertaken pursuant to the Lik Block Agreement.  The current agreement requires unanimous approval by the parties for 
annual expenditures in excess of $1 million.  The Company and Teck American are currently negotiating a new joint operating 
agreement that updates and clarifies the language of the original agreement, but preserves the intent of the original agreements.  

3.  Accessibility, Climate, Local Resources, Infrastructure and Physiology 

Access to the Lik property is by air to a gravel surfaced airstrip located on the property. The airstrip is capable of 

handling multi-engine cargo planes. Charter flights may be arranged from a number of sites in northwestern Alaska. The town 
of Kotzebue, which is located about 90 miles from the deposit, is a seaport and is serviced by a regular air service from 
Anchorage. Kotzebue is the center for access to the nearby Red Dog mine operated by Teck American. 

The nearest location for which climatic data is available is the town of Kotzebue. The average annual temperature at 

Kotzebue is 21.6oF, with seasonal extremes ranging between 77oF in summer to -58oF in winter. There is an average of 9 inches 
of rain per year and a snowfall of 47 inches per year. Snow falls are not extreme, but blowing snow may form significant drifts. 
Strong winds are common in most parts of Alaska. Currently, diamond drilling is possible at the Lik property between June 1 
and October 1.  

The exposures of mineralization at the Lik property are located at about 800 feet above sea level. West of the deposit, 

the land rises steeply to peaks about 2,300 feet above sea level. To the southeast, the land slopes down to the Wulik River 
where the bottom of the valley is about 700 feet above sea level. There is sufficient space for tailings and waste rock disposal, 
and sufficient water is expected to be available for any proposed processing.  Locally, there is vegetation on the property 
consisting of tundra grasses and low brush made up of willow, dwarf birch, and alder. 

There is a camp located on the Lik property. The camp has been used periodically over the last twelve years and was 

substantially refurbished as a part the 2007 and 2008 field programs. The supply of electric power and workforce 
accommodation will have to be developed.  There are no local resources adjacent to the Lik property. The Red Dog mine, 
operated by Teck American, is located about 13.6 miles southeast of the deposit. Potentially, concentrates could be moved 
along the access road from the Red Dog mine to the port on the Chukchi Sea.  The port has a shipping season in excess of 
100 days.  

Zazu entered into an agreement with Alaska Industrial Development and Export Agency (“AIDEA”) to enable AIDEA 

to begin due diligence on the proposed expansion of the port and the Red Dog road, the Delong Mountain Transportation 
System (“DMTS”), to potentially handle Lik concentrates.  AIDEA, as owners of the DMTS, evaluated their possible role in 
the two parts of the proposed expansion project:  the financing of a spur road connecting the Lik project to the DMTS, and the 
financing of any required modifications at the port.  The DMTS is open to multiple users such as the Company.   The studied 
expansion would facilitate both the development of the Lik project, and handle future concentrate production from the project.  
The DMTS road and port system currently handles all concentrate produced by the Red Dog zinc mine of Teck.    Prior to the 
AIDEA agreement, Zazu received a letter of Non-Objection from the Northwest Arctic Borough (“NWAB”).  In this letter, the 
NWAB formally acknowledged its awareness of the Lik project, and that NWAB had no objection to the project. 

In January 2015, AIDEA announced the completion of its study into capacity availability in its DMTS.  The report 
concluded that there is sufficient excess capacity for the Company’s concentrate shipping needs, confirming the assumptions 
made in Zazu's 2014 PEA.  This study aimed to closely identify the outputs of both Lik and Red Dog, if any modifications are 
required to the DMTS to support them, and if so, their potential cost.  The study concluded that sufficient handling capacity 
will exist with only minor modifications required to accommodate future planned production from Lik under the analyzed PEA 
scenario. 

4.  History 

The Red Dog ore deposit was originally discovered in 1970 by a geologist undertaking mapping in the De Long 

Mountains area on behalf of the United States Geological Survey.  GCO, in joint venture with New Jersey Zinc Company and 
WGM Inc., carried out stream geochemical sampling and reconnaissance for color anomalies. Claims were staked in July 1976 
to cover a stream geochemical anomaly on Lik Creek. HOMEX replaced New Jersey Zinc Company in the joint venture in 
1976/1977. 

18 

 
 
 
 
 
 
 
 
 
 
Diamond drilling on the Lik property commenced in 1977 and targeted a gossan with a coincident soil and 
electromagnetic anomaly. The first hole encountered massive lead-zinc-silver-bearing sulfides. By the end of 1977, the joint 
venture had completed 25 line-miles of ground geophysics, a soil sampling program, and ten diamond drill holes with an 
aggregate depth of 5,260 feet.  In 1978 and 1979, further geological, geochemical and geophysical surveys were carried out, 
together with the drilling of another 93 diamond drill holes aggregating 51,200 feet. A mineral resource was estimated.  The 
joint venture continued to work in the district in the period 1980 to 1983. However, only limited diamond drilling activity 
continued on the Lik property. The Lik Block Agreement was signed in 1984. 

In 1984, Noranda optioned the GCO holding of the Lik property.  Much of Noranda’s activity was concentrated in the 
Lik North Area where ten diamond drill holes with an aggregate depth of 13,710 feet were completed on four sections. Noranda 
also drilled holes in the Lik South deposit to better define the deposit.  Noranda released its interest in the Lik property after a 
re-organization of its holdings in the United States.  From 1985 through June of 2007, when Zazu acquired its interest in the 
Lik property, only a limited amount of work was conducted at Lik. 

Zazu completed two diamond drilling programs during the 2007 and 2008 summer field seasons, all of it directed to 

testing the Lik South deposit. In 2009 and 2010, Zazu conducted a suite of economic, engineering, environmental and 
metallurgical studies on the Lik property, as well as continued exploration and in-fill drilling. 

5. Geological Setting 

The regional geology of the Western Brooks Range area is structurally complex. The sedimentary rocks of the area 

have been significantly disrupted by thrust sheets.  The Lik property and the other zinc-lead deposits of the Brooks Range, 
including Red Dog, are hosted in the Kuna Formation of the Lisburne Group. In the Western Brooks Range, the Lisburne 
Group includes both deep and shallow water sedimentary facies and local volcanic rocks. The rocks have been extensively 
disrupted by thrusting. The deep water facies of the Lisburne Group, the Kuna Formation, are exposed chiefly in the Endicott 
Mountains. 

On a district scale, the Lik property is hosted in the Red Dog plate of the Endicott Mountains thrust sheet. The 

stratigraphically lowest rocks within the Red Dog plate belong to the Kayak Shale. The top of the Kayak Shale is interbedded 
with rocks of the Kuna Formation.  The Ikalukrok Unit has been divided into a lower laminated black shale sub-unit and an 
upper medium- to thick-bedded black chert sub-unit. The Ikalukrok Unit hosts all of the massive sulfide deposits in the area.   

Locally, the Lik property is hosted in the upper part of the Ikalukrok Unit of the Kuna Formation. The host rocks are 

carbonaceous and siliceous black shale, with subordinate black chert and fine-grained limestone. These rocks strike broadly 
north-south and dip at about 25o to 40o to the west. The massive sulfides are overlain conformably by rocks of the Siksikpuk 
Formation. The sequence is overridden by allochthonous rocks that form high hills north and west of the deposits. 

The mineralized sequence is cut by a number of faults. The most significant disruption is the Main Break Fault, which 
drops the northern end of the Lik deposit down about 500 feet. It is unclear whether there is a change in strike north of the fault, 
or whether the change is more apparent due to topography. The Main Break Fault strikes east-west and dips north at about 60o. 
There is another group of steeper faults that tend to strike northerly or northwesterly and which are interpreted as being both 
normal and reverse with throws of up to 330 feet.  The drilling in 2008 appears to demonstrate that several of these faults are 
non-existent or more minor than previously interpreted. 

6. Prior Exploration 

The Red Dog ore deposit was originally discovered in 1970 by a geologist undertaking mapping in the De Long 

Mountains area on behalf of the United States Geological Survey.  GCO carried out stream geochemical sampling and 
reconnaissance for color anomalies.  Claims were staked in July 1976 to cover a stream geochemical anomaly on Lik Creek. 
The Lik property was drill tested in the late 1970’s and early 1980’s and sporadically through the early 1990s.  Details of these 
historical drilling campaigns are discussed above under the heading “History” and below under the heading “Drilling.”    

Zazu completed significant diamond drilling campaigns in the summers of 2007 and 2008. The details of these 
programs, and the results of the work, are discussed below under “Drilling”. The Company also contracted Zonge Engineering 
& Research Organization, Inc. to complete a Controlled- and Natural-Source Audio-frequency Magnetotelluric (CSAMT and 
NSAMT) surveys in 2008.   

7. Mineralization  

19 

 
 
 
 
 
 
 
 
 
 
 
 
 
The Lik deposit is a black shale-hosted stratiform zinc-lead-silver sedimentary-exhalitive (SEDEX) deposit. 
Mineralization is syngenetic with respect to sediment deposition. Silicification occurs within and peripheral to the main mass of 
sulfides.  Major sulfides in decreasing order of abundance are pyrite-marcasite, sphalerite and galena. The ore textures are 
massive, fragmental, chaotic, and veined; they rarely show typical sedimentary layering.  The upper portion of the ore body 
near the surface is oxidized.  The deposit is continuous outside the Lik property onto the adjacent 100%-owned Teck American 
property to the south. The southern continuation of the Lik deposit is referred to as the Su deposit, lying on Teck American’s 
Su property.   

Within the Lik property, the deposit is divided into two parts by the Main Break Fault. The main part of the deposit 

within the existing claims is referred to as the Lik South deposit. As presently tested, the Lik South deposit has a surface 
footprint of about 3,600 feet long and about 2,000 feet wide.  It has been tested down dip to a depth of about 650 feet.  The Lik 
South deposit remains open down dip.  North of the Main Break Fault, the Lik North deposit has a surface footprint of about 
2,300 feet long and about 1,150 feet wide.  It has been tested down dip to a depth of about 1,000 feet.  The Lik North deposit 
remains strongly open down dip and to the north. 

The deposits strike northerly and dip westerly at about 25o to 40o. The mineralization comprises irregular, stratiform 
lenses. The mineralogy of the sulfides is simple and comprises pyrite, marcasite, sphalerite, and galena, with rare tetrahedrite, 
bournonite and boulangerite. Gangue minerals include quartz (as chert), clay minerals, carbonate and barite. Noranda 
recognized six different ore types in its logging of drill core. Typical grades of mineralized intersections within the Lik deposit 
are listed in the table below:

Previous work by GCO determined that sulfides were deposited in four distinct cycles.  Individual cycles may be quite 
thin near the margins of the deposit and the thickest accumulation in a single cycle noted to date is about 45 feet.  The base of a 
sulfide cycle begins abruptly with the deposition of sphalerite, galena and pyrite. Typically, the highest grades are found at or 
within 5-10 feet of the base of a sulfide cycle. In the central portion of the deposit several cycles are stacked and comprise a 
cumulative thickness of up to 100 feet of mineralization.

Totals 

Zazu completed two diamond drilling programs during the 2007 and 2008 summer field seasons, all of it directed to 

testing the Lik South deposit. The 2007 program was designed to confirm previous drilling results, commence an in-fill drilling 
program for Lik South and to obtain samples for metallurgical testing.  None of the drilling in 2007 or 2008 was designed to 
test the Lik North deposit.  The 2007 program consisted of 11 core holes for a total of 4,572 feet. The 2008 program consisted 
of 58 drill holes for a total of 22,400 feet.  All of the 2008 diamond drilling was HQ-size core.  At the end of 2008, most of the 
Lik South deposit had been tested on lines spaced at 200 ft. with holes spaced at about 100 ft. 

The 2011 25-hole core drilling program (12,700 feet) at Lik combined exploration and development drilling.  The 

exploration drilling focused on improving resource definition, in particular near the transition zone between Lik South and Lik 
North and also Lik North.  The development drilling focused on obtaining additional metallurgical samples and geotechnical 
drilling for the open pit design and foundation information to assist in infrastructure design.  By the end of 2011, a total of 
125,300 feet of drilling in 229 holes had been completed on the Lik property by the Company and the previous owners.  No 
drilling has been completed on the Lik project since 2011. 

9. Sampling, Analysis and Security of Samples 

Pre-Zazu Drilling   

Core recoveries were typically high within the massive sulfides, but lower, more variable recoveries were obtained in 

the unmineralized and weakly mineralized sections.  The entire core obtained from the Lik deposit, usually NQ-size, was 
logged on site.  All of the core containing sulfide mineralization was sawn using diamond saws and half of the core was sent for 
assay. Reference samples were not included in the sample stream. Sample lengths in massive sulfides were typically from two 
to three feet, but occasionally up to nine feet. Sample lengths were probably controlled by geology and the location of depth 
markers in the core boxes.  

Most of the samples were assayed by Bondar Clegg Laboratory Group (“Bondar Clegg”) of Vancouver. At various 

times, the laboratory maintained preparation facilities in Anchorage and Fairbanks Alaska. In the initial years, when the bulk of 
the drilling was completed, it is believed that sample preparation and analysis were carried out in Vancouver. Bondar Clegg 
was not a registered laboratory at that time. However, Bondar Clegg was a recognized, reputable laboratory and was 
experienced in the use of atomic absorption spectrophotometry. 

As the entire core was logged and sampled in an isolated field camp, security was not a major concern because access 

to the camp was closely controlled.  It is noted that four different companies (WGM, GCO, Noranda and Moneta) have 
completed drilling programs at the Lik property and all of them have obtained consistent results. The work was considered 
completed to industry standards in use at the time of the work. Sample preparation was completed in the assay laboratory.

Drill core obtained during the 2007, 2008 and 2011 drilling campaigns was logged on site. The entire core containing 

sulfide mineralization was sawn using diamond saws and half of the core was sent for assay. All massive and high-sulfide cores 
were sampled.  Visual methods were used to select sample boundaries and lengths. The mineralization at Lik is considered to 
be appropriately logged and sampled. It is not evident that logging or sampling is leading to any bias in the sample results.  An 
examination of logging showed that core recovery in sulfide areas was generally very high. 

Core drilled in 2007 was placed in the sample bags, the air was evacuated and replaced with nitrogen. The samples 
were sent to Kotzebue by charter and then by licensed carrier to Anchorage. The samples were stored under refrigeration in 
Anchorage.  The samples were dispatched to G & T Metallurgical Services Ltd. (“G & T”) of Kamloops, British Columbia, an 
ISO 9001:2000 certified laboratory for precious metals and base metals.  As well as completing metallurgical testing, G & T 
crushed and analyzed the samples.  The 2008 diamond drill core was not required for metallurgical testing and core was 
handled normally. Sawn samples were securely bagged and boxed on site and dispatched to a facility of ALS Laboratory Group 
(“ALS Chemex”) located in Fairbanks, Alaska, for sample preparation. Transportation of the samples was through third-party 
companies that provided secure transportation services.  The pulps were analyzed at ALS Chemex located in Fairbanks or Elko, 
Nevada. Zazu did not participate in any part of the sample preparation or analysis except for cutting core. 

Check samples from the 2007 drilling program and all samples from the 2008 drilling campaign were sent to the 

preparation and assaying facilities of ALS Chemex (ISO 17025 accreditation).   Other QA/QC procedures employed by Zazu 
included the use of blanks (unmineralized core from outside of the mineralized zone) and quartered core duplicates. Zazu was 
unable to obtain acceptable reference samples for the 2007 field season and reference samples were not included as part of the 
2007 ongoing QA/QC program.  Reproducibility between G & T and ALS Chemex was found to be good.  A detailed 
description of QA/QC procedures can be found in the Solitario’s Canadian SEDAR filings and in the Company’s US Edgar 
filings:  Technical Report;  Zazu Metals Corporation, Lik Deposit, Alaska, USA; Report Date: April 23, 2014; Effective Date: 
March 3, 2014; prepared by JDS Energy and Mining Inc (“JDS”). 
. 
10. Prefeasibility Studies 

Zazu completed a Preliminary Economic Assessment in 2014 that incorporated a variety of prefeasibility level studies 
into the analysis.  These studies included resource estimation, mining and processing recovery estimates, a preliminary mining 
and processing plan, infrastructure layout, environmental considerations and an economic analysis based on the base case 
parameters.  The PEA envisioned an open pit mining operation with a 5,500 ton per day floatation mill for processing resulting 
in a nine-year mine life.  Concentrates would be handled through the DMTS road and port system that currently handles all 
concentrate produced by the nearby Red Dog zinc mine of Teck American.  A summary of metallurgical testing and mineral 
processing is provided below.  The PEA analyzed the Lik project as a stand-alone operation building its own independent 
processing, tailings and port facilities. 

Zazu engaged JDS to complete the PEA on the Lik deposit in 2013.  The NI 43-101 compliant study entitled: 
“Technical Report;  Zazu Metals Corporation, Lik Deposit, Alaska, USA; Report Date: April 23, 2014; Effective Date: March 
3, 2014;” can be found in the Company’s Canadian Sedar filings and is furnished in the Company’s U.S. Edgar filings.  JDS is 
a Canadian independent and internationally recognized mining engineering firm providing engineering services internationally.   

Metallurgical Testing and Mineral Processing 

There have been five metallurgical test work reports issued to date on the Lik ores. The most recent and 

comprehensive processing and metallurgical testing programs include work performed by G&T and by SGS.  Samples 
collected during drilling in 2007 and 2008 were composited into one Master Composite for testing at G&T in 2008, and later 
testing by SGS was carried out in 2010 on the remainder of the Master Composite. These key testing results have formed the 
basis for this economic evaluation of the Lik deposit. Results are summarized in the table below:

The metallurgical flowsheet for this PEA includes conventional crushing, grinding, and flotation processing methods. 

Run-of–Mine (ROM) ore will be delivered to a primary crushing plant and stored in a coarse ore stockpile awaiting reclaim 
into the grinding circuit. Crusher ore will be reclaimed and delivered to a two-stage grinding circuit equipped with a Semi-
Autogenous Grinding (SAG) mill and a ball mill in closed circuit with cyclones.  

Recoveries from these modeled methods and metallurgical testing conducted to date are anticipated to be 85% of zinc 
to the zinc concentrate and 69.7% of the lead to the lead concentrate.  Silver is also recovered and payable at times in the zinc 
concentrate and more significantly in the lead concentrate.  

11. Reserves 

There are no reported mineral reserves. 

12. Mining Operations 

No commercial mining operations to recover metals have occurred on the project.   

13. Planned Exploration and Development  

Solitario and Teck American, our 50% joint venture partner, have agreed to jointly fund a gravity geophysical 
program, continue baseline environmental work for mine permitting previously initiated by Zazu, and rehabilitate the Lik camp 
for 2018.  The objective of the gravity survey is to test for sub-surface gravity anomalies that may be associated with zinc 
deposits similar in nature to other Red Dog district zinc deposits.  Any gravity anomalies that are delineated may be potentially 
drill tested in 2019.  The 2018 program represents the first Teck-Solitario (Zazu) joint exploration effort since inception of the 
joint venture.  Teck American will manage the 2018 program, although Solitario will remain the manager of the joint venture. 

Chambara Zinc Property (Peru) 

In April 2008, we signed the Minera Chambara shareholders’ agreement with Votorantim on Solitario's 100%-owned 

Chambara zinc project.  In 2015 Votorantim transferred its interest in the Chambara project to Milpo, now Nexa.  For the 
remainder of this Chambara property section, all references to Votorantim, Milpo or Nexa will be collectively referred to as 
Nexa.    

 The original purpose of the Chambara joint venture was to collectively pool independently owned Solitario  
and Nexa properties into a jointly-held joint venture.  These properties were located within a large area of interest in northern 
Peru measuring approximately 200 by 85 kilometers, but outside of the Florida Canyon property position.   Nexa originally 
contributed 52 mineral concessions within the area of interest totaling 52,000 hectares to Minera Chambara for a 15% interest 
in Minera Chambara.  We contributed 9,600 hectares of mineral claims and an extensive exploration data base in our 
possession for an 85% interest in Minera Chambara.  Existing and future acquired properties subject to the terms of the 
shareholders’ agreement will be controlled by Minera Chambara.  Minera Chambara dropped selected concessions in 2013 and 
2016 and acquired the rights to 13 new concessions totaling 11,600 hectares in 2017.  This resulted in Minera Chambara 
holding 36,400 hectares of valid concessions that completely surround the Florida Canyon project area held by Minera 
Bongará.  As of December 31, 2016, Minera Chambara’s only assets are the properties and Minera Chambara has no debt.  
Nexa may increase its shareholding interest to 49% through cumulative spending of $6,250,000, and may further increase its 
interest to 70% by funding a feasibility study and providing for construction financing for Solitario's interest.  If Nexa provides 
such construction financing, we would repay that financing, including interest, from 80% of Solitario's portion of the project 
cash flow.

 The project has been on care and maintenance in recent years; however reconnaissance prospecting is planned for 
2018 following up previously identified geochemical anomalies.  Nexa is responsible for maintaining the property in good 
standing and making all concession payments to the Peruvian government.  Concession costs in 2018 to be paid by Nexa are 
estimated to be $130,000. 

La Promesa Project (Peru) 

The La Promesa property, acquired in 2008, consists of three concessions totaling 2,600 hectares.  Currently, our only 
holding costs for the mineral rights are annual payments of nine dollars per hectare to the Peruvian government.  Total holding 
costs in 2018 will be approximately $8,000.    A subsidiary of Newmont Mining Corporation holds a 2% net smelter return 
(“NSR”) on the property. 

During 2017 Solitario conducted an active social program with the communities located near the La Promesa project 

area with the objective of obtaining a community agreement to support exploration activities, including drilling.  In Peru, a 
community agreement is required in order to obtain drilling permits.  During 2018 our objectives are to complete an agreement 
with the local community, to conduct surface exploration, and if warranted, conduct a drilling program.    

At least five high-grade polymetallic veins have been identified and sampled at surface.  Two of the veins, about 300 
meters apart, have been traced for at least 400 meters along strike.  There appears to be a systematic trend towards greater vein 
thickness with depth, as the widest observed vein in outcrop occurs at the lowest elevation sampled to date.  Channel sampling 
along 300 meters of strike length from the best exposed vein yielded the following high-grade results:

Royalty Properties 

Yanacocha Royalty Property (Peru)  

The Yanacocha royalty property consists of43 concessions totaling approximately 40,500 hectares in northern Peru.  
The property position, located about 25 kilometers north of the city of Cajamarca, consists of a rectangular-shaped contiguous 
block of concessions nearly 40 kilometers long in an east-west direction and 25 kilometers wide in a north-south direction.  The 
southern and eastern boundary of the royalty property abuts Newmont Mining Corporation's Minera Yanacocha mining 
operation, a large gold mine currently in operation.  We held 100% interest in the concessions until April 2000, at which time 
we signed an agreement with Newmont Peru, Ltd., a wholly-owned subsidiary of Newmont Mining Corporation (both 
companies referred to as "Newmont Peru"), whereby we sold our Yanacocha Property to Newmont Peru for $6,000,000 and 
retained a sliding scale NSR royalty ("NSR-Royalty") that varied from two to five percent, depending on the price of gold.        

In January 2005 we signed an Amended and Restated Royalty Grant with affiliates of Newmont Peru to modify the 
NSR-Royalty schedule.  The modified royalty structure is classified into several categories, depending on the type of process 
used to recover each metal and the prices of the commodities subject to the royalty.  The royalty payable to Solitario is net of 
the government royalty burden imposed by Peru on the project ores.  Peru’s royalty imposes a sliding scale royalty varying 
from 1% to 12% of the operating profit of a mining operation.  The percentage royalty is determined by rule based on the 
operating margin; however, the minimum royalty is 1% of the revenues.  

No resources or reserves have been reported by Newmont Peru, nor has any mining been conducted on the property. 

Pedra Branca Platinum-Palladium Metals Project (Brazil)  

During 2015 we converted our operating interest in the Pedra Branca project to a 1% NSR interest.  The Pedra Branca 
platinum-palladium  project consisted of 46 exploration concessions totaling approximately 51,500 hectares in the Ceará State, 
Brazil.  The property is now owned by Garrison Capital Partners Limited, a Dubai, UAE company, which controls all activities 
related to the Pedra Branca project.

Montana Royalty Property (United States)  

In May 2016 we acquired a 1.5% net smelter royalty on non-producing exploration properties covering 16,548 acres in 

Montana previously owned by Atna Resources, Ltd.  

Mexico Royalty Properties 

During 2016 we transferred our 100% interest in 13 concessions totaling 3360 hectares in Mexico to a private 

Mexican party and retained a 1.5% NSR Royalty.  

Discontinued Projects 

During 2017, we abandoned our interests in the Aconchi and Norcan exploration properties in Mexico and we no 

longer hold any interest in those properties.  There was no capitalized mineral property interest in either of the interests and we 
did not record any mineral property write-downs during 2017. 

During 2016, we closed our exploration office in Mexico.  Solitario recorded a mineral property write-down of 

$10,000 related to the Norcan and Aconchi properties during 2016.  During 2016, Solitario abandoned its interest in its Canta 
Colorado property in Peru and recorded a mineral property write-down expense of $3,000 related to Canta Colorado.

Shares authorized for issuance under equity compensation plans 

On June 18, 2013 Solitario’s shareholders approved the 2013 Solitario Exploration & Royalty Corp. Omnibus Stock 

and Incentive Plan (the “2013 Plan”).  On June 29, 2017, Solitario shareholders approved an amendment to the 2013 Plan, 
which increased the number of shares available of common stock for issuance under the 2013 Plan from 1,750,000 to 
5,750,000.  Under the terms of the 2013 Plan, the Board of Directors may grant awards to directors, officers, employees and 
consultants.  Such awards may take the form of stock options, stock appreciation rights, restricted stock, and restricted stock 
units.  The terms and conditions of the awards are pursuant to the 2013 Plan and options are granted by the Board of Directors 
or a committee appointed by the Board of Directors.  There were no awards outstanding at December 31, 2016. 

In connection with the Acquisition, on July 12, 2017, Solitario granted 1,782,428 Replacement Options.  The exercise 

prices of the Replacement Options are between $2.24 per share and $0.70 per share with terms between 10 months and 18 
months. In accordance with the terms of the Acquisition, the Replacement Options were fully vested upon grant.  The 
Replacement Options had a grant date fair value of $164,000, based upon Black-Scholes models with an expected volatility of 
67% and a risk-free interest rate of 1.00%.  The grant date fair value was capitalized as part of the purchase price of the Zazu 
assets acquired in the Acquisition.   

On September 1, 2017, the Board of Directors granted 200,000 stock options under the 2013 Plan.  The options have a 
five-year life, vested 25% on the date of grant and vest 25% on each of the next three anniversary dates of the date of grant, and 
have an exercise price of $0.77 per share, and a grant date fair value of $84,000, based upon a Black-Scholes model with a an 
expected volatility of 64%, and a risk free interest rate of 1.70%.  Solitario recorded stock option compensation related to these 
options of $50,000 during 2017. 

On September 1, 2017, the Board of Directors granted, subject to shareholder approval at the next meeting of 

shareholders, an additional 2,300,000 stock options under the 2013 Plan to officers and members of the Board of Directors.  
These options have a five-year life, and exercise price of $0.77 per share, and a grant date fair value of $970,0000, based upon 
a Black-Scholes model with a volatility of 64%, and a risk free interest rate of 1.70%.  Although the options will vest on the

Item 7. Management's Discussion and Analysis of Financial Condition and Results of Operations  

The following discussion should be read in conjunction with the information contained in the consolidated financial 
statements and notes thereto included in Item 8, "Financial Statements and Supplementary Data."  Our financial condition and 
results of operations are not necessarily indicative of what may be expected in future years.   

(a). Recent Developments 

On July 12, 2017 we completed the acquisition of Zazu pursuant to the Arrangement Agreement and acquired all of the 

Zazu Shares by way of the Arrangement.  As a result of the Acquisition, Zazu became a wholly-owned subsidiary of Solitario.  
At closing, we issued 19,788,177 shares of common stock for all of the issued and outstanding Zazu Shares.  We also granted the 
Replacement Options in connection with the Acquisition.  The Acquisition was recorded as the acquisition of assets in 
accordance with ASU 2017-01.  The total purchase price for the Acquisition was $16,110,000 and has been allocated to the 
assets acquired and stock issuance costs, less liabilities.  Results of operations for Zazu have been included in our consolidated 
financial statements from the date of Acquisition. 

Effective July 17, 2017 an amendment to our Articles of Incorporation became effective that served to change our name 

to “Solitario Zinc Corp.” from “Solitario Exploration & Royalty Corp.”  Subsequent to the Acquisition, our core mineral 
property assets are the 39% interest in the Florida Canyon zinc project in Peru and the 50% ownership interest in the Lik zinc 
deposit (acquired in the Acquisition). We believe the name “Solitario Zinc Corp.” reflects the increased focus of the Company 
on zinc-related assets.    

(b). Business Overview and Summary 

We are an exploration stage company at December 31, 2017 under Industry Guide 7, as issued by the SEC.  We were 

incorporated in the state of Colorado on November 15, 1984 as a wholly-owned subsidiary of Crown Resources Corporation 
("Crown").  In July 1994, we became a publicly traded company on the Toronto Stock Exchange (the "TSX") through our initial 
public offering.  We have been actively involved in mineral exploration since 1993.  Our primary business is to acquire 
exploration mineral properties or royalties and/or discover economic deposits on our mineral properties and advance these 
deposits, either on our own or through joint ventures, up to the development stage (development activities include, among other 
things, completion of a feasibility study for the identification of proven and probable reserves, as well as permitting and 
preparing a deposit for mining).  At that point, or sometime prior to that point, we would likely attempt to sell a given mineral 
property, pursue its development either on our own, or through a joint venture with a partner that has expertise in mining 
operations, or obtain a royalty from a third party that continues to advance the property.  Upon the completion of the 
Acquisition, we have shifted our primary focus to the acquisition and exploration of zinc-related exploration mineral properties. 
In addition to focusing on our current assets and the evaluation of mineral properties for acquisition, we also evaluate potential 
strategic corporate transactions for the potential acquisition of new precious and base metal properties and assets with 
exploration potential or business combinations we determine to be favorable to Solitario.   

Our geographic focus for the evaluation of potential mineral property assets is in North and South America; however 

we have conducted property evaluations for potential acquisition in in other parts of the world.  Our exploration properties may 
be developed in the future by us or through a joint venture, although we have never developed a mineral property.   At 
December 31, 2017, we consider our carried interest in our Florida Canyon project in Peru and our recently acquired interest in 
the Lik project in Alaska to be our core mineral property assets.  In addition, at December 31, 2017, we have one exploration 
property in Peru, and one royalty property in each of Peru, Brazil, United States and Mexico.  We are conducting independent 
exploration activities in Peru and through joint ventures operated by our partners in Peru and the United States.  We conduct 
potential acquisition evaluations in other countries of both South and North America. 

As of December 31, 2017, we have significant balances of cash and short-term investments that we anticipate using, in 

part, to further the development of the Lik project, conduct initial exploration on the La Promesa project in Peru, and to 
potentially acquire additional mineral property assets.  The fluctuations in base and precious metals has contributed to a 
challenging environment for mineral exploration and development, which has created opportunities as well as challenges for 
the potential acquisition of advanced mineral exploration projects or other related assets at potentially attractive terms.      

In analyzing our activities, the most significant aspect relates to results of our exploration and potential development 

activities and those of our joint venture partners on a property-by-property basis.  When our exploration or development 
activities, including drilling, sampling and geologic testing, indicate a project may not be economic or contain sufficient 
geologic or economic potential we may impair or completely write-off the property.  Another significant factor in the success 
or failure of our activities is the price of commodities.  For example, when the price of gold is down, the value of gold-bearing 
30 

 
 
 
 
 
 
  
 
 
 
mineral properties decreases; however, when the price of gold is up it may become more difficult and expensive to locate and 
acquire new gold-bearing mineral properties with potential to have economic deposits.    

The potential sale, joint venture or development of our mineral properties will occur, if at all, on an infrequent basis.   

We have recorded revenues and met our need for capital in the past through (i) the sale of properties; (ii) joint venture 
payments, including delay rental payments; (iii) a royalty sale on our former Mt. Hamilton property during 2012; (iv) the sale 
of our shares of Vendetta and Kinross common stock; (v) long-term debt secured by our mineral property; (vi) short-term 
margin borrowing; and (vii) issuances of common stock.  In 2015 we recorded a gain on the sale of our interest in Mount 
Hamilton LLC (“MHLLC”) of $12,309,000.  During June 2012, we sold a royalty interest in our Mt. Hamilton project to 
Sandstorm Gold Ltd. for $10,000,000.  Previous to the Mt. Hamilton Transaction, our last significant cash proceeds were 
recorded in 2000 upon the sale of our former Yanacocha property for $6,000,000.  Proceeds from the sale or joint venture of 
properties, although significant when they occur, have not been a consistent annual source of cash and would occur in the 
future, if at all, on an infrequent basis.  We have reduced our exposure to the costs of our exploration activities in the past 
through the use of joint ventures.  Although we anticipate the use of joint venture funding for some of our exploration activities 
will continue for the foreseeable future, we can provide no assurance that these or other sources of capital will be available in 
sufficient amounts to meet our needs, if at all. 

(c). Results of Operations 

Comparison of the year ended December 31, 2017 to the year ended December 31, 2016 

We had a net loss of $942,000 or $0.02 per share for the year ended December 31, 2017 compared to a loss of 
$1,710,000 or $0.04 per basic and diluted share for the year ended December 31, 2016.  As explained in more detail below, the 
primary reason for decrease in net loss during 2017 compared to 2016 was the reduction in general and administrative expense 
to $1,202,000 during 2017 compared to general and administrative expense of $2,163,000 during 2016.  This decrease was 
primarily related to a reduction in non-cash stock option expense to $50,000 during 2017 compared to stock option expense of 
$970,000 during 2016.  Other factors contributing to the decrease in net loss included (i) an increase in the gain on the sale of 
marketable equity securities during 2017 to $578,000 compared to a gain of $40,000 during 2016; (ii) an increase in interest 
income during 2017 to $124,000 compared to interest income of $44,000 during 2016; (iii) no property abandonment losses 
were recorded during 2017 compared to property abandonment losses of $13,000 during 2016 and (iv) no losses on the sale of 
assets were recorded during 2017 compared to a loss on asset sales of $14,000 during 2016.  Partially offsetting these factors 
that served to decrease our net loss from operations were (i) an increase in exploration expense to $699,000 during 2017 
compared to exploration expense of $628,000 during 2016; (ii) a decrease in deferred income tax benefit to nil during 2017 
compared to an income tax benefit of $353,000 during 2016; and (iii) a decrease in gain on derivative instruments to $271,000 
during 2017 compared to a gain on derivative instruments of $672,000 during 2016.  Each of these items is discussed in greater 
detail below. 

On July 12, 2017 we completed the acquisition Zazu pursuant to the Arrangement Agreement, which was a significant 

focus of our attention during 2017.  As part of the Acquisition, we capitalized the purchase price of $16,110,000, including 
approximately $782,000 of transaction costs, including investment banking fees, legal and other costs.  The total purchase price 
for the Acquisition has been allocated to the assets acquired, less liabilities.  Results of operations for Zazu have been included 
in our consolidated financial statements from the date of Acquisition. 

Our other primary activities during 2017 and 2016 was the evaluation of mineral properties and other junior mining 

companies for possible acquisition and or merger, with an increase in related reconnaissance exploration activities and expense.   
These activities included the completion of a PEA related to our Florida Canyon project in Peru.  The total cost of the PEA was 
approximately $243,000 of which our joint venture partner, Nexa paid one-half.  During 2017, we evaluated several projects for 
acquisition, in addition to the Lik project acquired in the Acquisition.  We decided to close our Mexico exploration office 
during 2016; however this reduction in exploration was more than offset by the exploration and evaluation efforts of our staff 
and contract geologists during 2017.  We did no drilling on any of our exploration projects in North or South America during 
2017 or 2016.  Our 2018 exploration and development expenditure budget is approximately $792,000, which is expected to be 
directed toward the exploration of our existing mineral exploration projects as well as the evaluation and potential acquisition 
of new mineral exploration properties.  This expenditure amount could increase significantly if we decide to conduct 
exploration drilling on any of our existing projects, which is not currently included in the 2018 budget.  We cannot predict with 
certainty that we will acquire new mineral exploration properties during 2018; however, we expect to continue our early-stage 
exploration activities.  Our exploration activities may be modified, as necessary for any drilling programs we may undertake, 
changes related to potential acquisition of new properties, joint venture funding, commodity prices and deployment of our 
capital.

We believe a discussion of our general and administrative costs should be viewed without the non-cash stock option 

compensation expense which is discussed below.  Excluding these costs, general and administrative costs were $1,152,000 
during 2017 compared to $1,193,000 during 2016.  We reduced salary and benefits expense to $639,000 during 2017 compared 
to $708,000 during 2016 as a result of salary and bonus reductions.  In addition, (i) legal and accounting costs increased 
slightly to $134,000 during 2017 compared to $126,000 during 2016; (ii) travel and investor relation costs increased to 
$233,000 during 2017 compared to $177,000 during 2016 as a result of expenses related to our post Acquisition disclosures and 
market activities; (iii) we recorded additional costs for directors and officer insurance of $55,000 during 2017 compared to 
$5,000 during 2016 as we previously had not carried director and officer insurance; and (iv) other costs related to office, 
insurance and miscellaneous costs increased slightly to $98,000 during 2017 compared to $90,000 during 2016 primarily due to 
increases in rent and office costs.  We anticipate general and administrative costs for 2018 will be comparable to the costs 
incurred during 2017; however this amount may vary significantly during 2018 depending on the outcome of our property 
evaluations and any strategic transactions we may attempt to execute upon, which cannot be predicted at this time.  We have 
forecast 2018 general and administrative costs to be approximately $1,217,000, excluding non-cash stock option compensation 
expense.    

We account for our employee stock options under the provisions of ASC 718.  We recognize stock option 
compensation expense on the date of grant for 25% of the grant date fair value, and subsequently, based upon a straight line 
amortization of the grant date fair value of each of its outstanding options.  During the year ended December 31, 2017, we 
recorded $50,000 of non-cash stock option expense for the amortization of our outstanding options grant date fair value with a 
credit to additional paid-in-capital compared to $970,000 of non-cash stock option compensation expense during 2016.   On 
August 24, 2016, holders of option awards voluntarily cancelled awards for 390,000 options from our 2006 Plan and 1,699,000 
options from our 2013 Plan.   No consideration was given or received by the holders of the options to cancel the awards.  The 
cancellation of the awards for 1,699,000 options from our 2013 Plan on June 22, 2016, and the related 25% expense of the 
grant date fair value on that date, accounted for the increase in the non-cash stock option compensation during 2016 compared 
to 2017.  See Note 9, “Employee Stock Compensation Plans,” to our consolidated financial statements in Item 8, “Financial 
Statements and Supplementary Data” for an analysis of the changes in the fair value of our outstanding stock options and the 
components that are used to determine the fair value.   

During 2017 we received proceeds of $666,000 and recorded a gain on the sales of $578,000 from the sale of 
3,480,000 Vendetta common shares, and used the bulk of the proceeds of $666,000 to exercise 7,240,000 warrants to acquire 
Vendetta common shares for $578,000.  See Note 3, “Marketable Equity Securities,” to the consolidated financial statements in 
Item 8, “Financial Statements and Supplementary Data” of this Form 10-K for a discussion of the sale of Vendetta shares and 
the exercise of the Vendetta Warrants (defined below).  As of December 31, 2017, we have 11,000,000 shares of Vendetta 
common stock and no remaining Vendetta Warrants.  This compared to the sale of 3,000 shares of Kinross common stock for 
proceeds of $10,000 and a gain on sale of $8,000 and the sale of 250,000 shares of International Lithium Corp marketable 
equity securities for proceeds of $45,000 and at a gain of $32,000 during 2016.  We may sell some of our marketable equity 
securities from time to time during 2018 for working capital needs; however we do not expect to sell all of our holdings of 
marketable equity securities during 2018.  Any proceeds we may receive from sales of marketable equity securities during 2018 
will be dependent on the quoted market price of the securities sold on the date of sale and may be at prices below the fair value 
at December 31, 2017.  See “Liquidity and Capital Resources” below.       

During 2017 we recorded a gain on derivative instruments of $271,000 compared to a gain on derivative instruments 

of $672,000 during 2016.  The gains during 2016 and 2017 were primarily related to our investment in Vendetta Warrants, 
which were purchased on May 2, 2016, as part of our strategic investment in Vendetta, where we acquired 7,240,000 units for 
Cdn$0.05 per unit, with each unit consisting of one share of Vendetta common stock and one Vendetta Warrant.  Each 
Vendetta Warrant entitled Solitario the right to acquire one share of Vendetta common stock at a price of Cdn$0.10 per share 
for a period of two years (“Vendetta Warrant”).  We recorded a gain on derivative instruments of $216,000 during 2017 related 
to the Vendetta Warrants compared to a gain of $629,000 during 2016 related to the Vendetta Warrants.  These gains were 
primarily as a result of an increase in the price of the underlying Vendetta common shares during 2017 and 2016.  The 
remaining increase in the gain on derivative instruments was related to the sale of Kinross calls during 2017 of $54,000 and the 
32 

 
 
 
 
 
 
sale of Kinross calls during 2016 of $43,000.  We have sold covered calls on a limited portion of our Kinross common stock 
that we intend to sell within one year, to enhance our return on Kinross common stock in exchange for potential upside in those 
covered Kinross shares.  We may continue to sell covered Kinross call options during 2018.   See Note 6, “Derivative 
Instruments,” to our consolidated financial statements in Item 8, “Financial Statements and Supplementary Data,” for an 
analysis of the changes in our derivative instruments, and the components that are used to determine the fair value of our 
derivative instruments.   

We recorded $13,000 of depreciation and amortization during 2017 compared to $5,000 of depreciation and 
amortization during 2016.  The increase is primarily as a result of additional equipment acquired in the Acquisition at the Lik 
project being depreciated.  We amortize these assets over a five-year period.  We anticipate our 2018 depreciation and 
amortization costs will be higher than the 2017 amount as a result of owning the Lik assets for a full year in 2018.  

We recorded interest income of $124,000 during 2017 compared to interest income of $44,000 during 2016.  The 

increase during 2017 was related to the investment of the net proceeds from the Mt. Hamilton Transaction in short-term 
certificates of deposit and United States Treasury notes since the date of the Mt. Hamilton Transaction as well as an increase in 
nominal interest rates during 2017 compared to 2016.  We anticipate our interest income will decrease in 2018 compared to 
2017 as a result of the use of our short-term investments and our cash balances for the exploration, evaluation and or 
acquisition of mineral properties discussed above.  See “Liquidity and Capital Resources,” below, for further discussion of our 
cash and cash equivalent balances.   

During 2017 we recorded no deferred tax expense compared to deferred tax expense of $353,000 during 2016 to other 

comprehensive income related to the net change in the in the unrealized value of our marketable equity securities, with a 
corresponding deferred tax credit of $353,000 to income tax expense in the statement of operations during 2016.  See Note 3, 
“Marketable Equity Securities” and Note 5, “Income Taxes” to our consolidated financial statements in Item 8, “Financial 
Statements and Supplementary Data of this Form 10-K for additional discussion of our income tax valuation allowance, 
deferred tax assets and our net operating losses for 2017 and 2016. We continue to provide a valuation allowance for our 
United States and foreign net operating losses, which are primarily related to our general and administrative expenses and to 
our exploration activities in Alaska and Peru.  We anticipate we will continue to provide a valuation allowance for these net 
operating losses until we are in a net tax liability position with regards to those countries where we operate or until it is more 
likely than not that we will be able to realize those net operating losses in the future.       

We regularly perform evaluations of our mineral property assets to assess the recoverability of our investments in 

these assets.  All long-lived assets are reviewed for impairment whenever events or circumstances change which indicate the 
carrying amount of an asset may not be recoverable utilizing guidelines based upon future net cash flows from the asset as well 
as our estimates of the geologic potential of early stage mineral property and its related value for future sale, joint venture or 
development by us or others.  During 2016, we closed our exploration office in Mexico.  Solitario recorded a mineral property 
write-down of $10,000 related to the Norcan and Aconchi properties during 2016.  During 2016, we abandoned our interest in 
its Canta Colorado property in Peru and recorded a mineral property write-down expense of $3,000 related to Canta Colorado.  
In addition, we recorded a loss on other assets in Mexico of $14,000 related to the exit from its exploration activities in Mexico 
during 2016.  We had no mineral property impairments during 2017.   

(d). Liquidity and Capital Resources  

Cash  

As of December 31, 2017 we have $214,000 in cash.  We intend to utilize a portion of this cash and a portion of our 
short-term investments, discussed below, to fund our exploration activities and the potential acquisition of mineral properties 
and other assets over the next several years.  We may also use a portion of these assets to repurchase shares of our common 
stock, pursuant to the terms of a stock buy-back program discussed below.     

Short-term Investments 

As of December 31, 2017, we have $10,395,000 of our current assets in United States Treasury securities (“USTS”) 
with maturities of 15 days to eighteen months.  The USTS are recorded at their fair value, based upon quoted market prices.  
The USTS are highly liquid and may be sold in their entirety at any time at their quoted market price and are classified as a 
current asset.  We anticipate we will roll over that portion of our USTS not used for operating costs or mineral property 
acquisitions as they mature during 2018. 

As of December 31, 2017 we have $1,247,000 in separate bank certificates of deposit (“CDs”) each with a maximum 
value of $250,000, and each of which are covered by Federal Deposit Insurance Corporation insurance to the full face value of 
the CDs.  At December 31, 2017, the CDs have maturities of between seven and fifteen months.  The CDs are recorded at their 
33 

 
  
 
 
 
 
 
 
 
fair value, based upon quoted market prices.  The CDs are highly liquid and may be sold in their entirety at any time at their 
quoted market price and are classified as a current asset.  We anticipate we will roll over that portion of our CDs not used for 
operating costs or mineral property acquisitions as they mature during 2018. 

Marketable Equity Securities 

Our marketable equity securities are classified as available-for-sale and are carried at fair value, which is based upon 
market quotes of the underlying securities.  We owned 100,000 shares of Kinross common stock at December 31, 2017.  The 
Kinross shares are recorded at their fair value of $432,000 at December 31, 2017.  As of December 31, 2017, we own 
11,000,000 shares of Vendetta common stock recorded at their fair market value of $2,191,000 based upon quoted market 
prices.  In addition we own other marketable equity securities with a fair value of $20,000 as of December 31, 2017 based upon 
quoted market prices.  Changes in the fair value of marketable equity securities are recorded as gains and losses in other 
comprehensive income in shareholders’ equity.  

Working Capital 

We had working capital of $14,472,000 at December 31, 2017 compared to working capital of $16,671,000 as of 

December 31, 2016.  Our working capital at December 31, 2017 consists primarily of our cash and cash equivalents, our 
investment in USTS and CDs, discussed above, and our marketable equity securities of $2,643,000, less our accounts payable 
of $141,000.  As of December 31, 2017, our cash balances along with our short-term investments and marketable equity 
securities are adequate to fund our expected expenditures over the next year.  

The nature of the mineral exploration business requires significant sources of capital to fund exploration, development 

and operation of mining projects.  We expect we will need additional capital if we decide to develop or operate any of our 
current exploration projects or any projects or assets we may acquire. We anticipate we would finance any such development 
through the use of our cash reserves, short-term investments, joint ventures, issuance of debt or equity, or the sale of other 
exploration projects or assets. 

Stock-Based Compensation Plans 

At December 31, 2017, options to acquire 1,982,428 shares of our common stock were outstanding, of which 

1,782,428 options were Replacement Options granted in connection with the Acquisition.  The options were granted with 
exercise prices ranging from $1.74 per share to $0.54 per share.   There are 1,832,428 options that are vested and exercisable at 
December 31, 2017.  Of these options, there are options exerciseable to acquire 214,320 shares priced at $0.54 per share that 
are in the money with an exercise price below the current market price of a share of Solitario common stock as quoted on the 
NYSE American exchange.  In addition, on September 1, 2017, our Board of Directors granted, subject to shareholder approval 
at the next meeting of shareholders, an additional 2,300,000 stock options under the 2013 Plan to officers and members of the 
Board of Directors.  These options have a five-year life, an exercise price of $0.77 per share, and a grant date fair value of 
$970,0000, based upon a Black-Scholes model with a volatility of 64%, and a risk free interest rate of 1.70%.  Although the 
options will vest on the schedule of 25% on date of grant and 25% on each of the next three anniversary dates of the date of 
grant, the options will not become exercisable in whole or in part unless our shareholders approve the grants, and the option 
grants will be void if Solitario shareholders do not approve the grants.  See Note 9, “Employee Stock Compensation Plans” to 
our consolidated financial statements in Item 8, “Financial Statements and Supplementary Data of this Form 10-K for a 
discussion of the activity in our 2013 Plan and our 2006 Plan during 2017 and 2016.  We do not anticipate that stock option 
exercises will be a significant source of cash during 2018. 

Share Repurchase Program 

On October 28, 2015, our Board of Directors approved a share repurchase program that authorized us to purchase up 

to two million shares of our outstanding common stock through December 31, 2016.  During 2016, our Board of Directors 
extended the term of the share repurchase program until December 31, 2017.  During 2017 our Board of Directors extended the 
term of the share repurchase program until December 31, 2018.  All shares purchased to date have been cancelled and reduced 
the number of shares of outstanding common stock.  The amount and timing of any shares purchased has been and will be 
determined by our management and the purchases will be effected in the open market or in privately negotiated transactions 
based upon market conditions and other factors, including price, regulatory requirements and capital availability and in 
compliance with applicable state and federal securities laws.  Purchases may also be made in accordance with Rule 10b-18 of 
the Exchange Act.  The repurchase program does not require the purchase of any minimum number of shares of common stock 
by the Company, and may be suspended, modified or discontinued at any time without prior notice.  No purchases will be made 
outside of the United States, including on the Toronto Stock Exchange.  Payment for shares of common stock repurchased 
under the program will be funded using the Company’s working capital. As of December 31, 2017, since the inception of the 

34 

 
 
 
 
 
 
 
 
 
share repurchase program, we have purchased a total of 667,800 shares for an aggregate purchase price of $348,000 and these 
shares are no longer included in our issued and outstanding shares.  We anticipate we will continue to purchase a limited 
number of shares under the share repurchase plan during 2018 as determined by management. 

Off-balance sheet arrangements 

As of December 31, 2017 and 2016, we have no off-balance sheet arrangements.  

(e). Cash Flows  

Net cash used in operations during the year ended December 31, 2017 decreased to $1,685,000 compared to 
$1,835,000 for 2016 primarily as a result of (i) additional interest income of $124,000 during 2017compared to $44,000 during 
2016 (ii) a slight reduction in non-stock option general and administrative expenses of $1,151,000 during 2017 compared to 
$1,193,000 during 2016, discussed above under “Results of Operations; and (iii)  reduction in prepaid expenses as well as a 
slight increase in accrued accounts payable during 2017 compared to the change in these accounts during 2016.  Partially 
offsetting this decreased use of cash in operations was an increase in reconnaissance exploration activities to $699,000 during 
2017 compared to exploration expense of $628,000 during 2016 as discussed in further detail above under “Results of 
Operations.”   

Net cash used in investing activities decreased to $1,785,000 during 2017 compared to a use of cash of $15,516,000 

during 2016.  The primary use of cash during 2016 was the net purchases of CD and USTS short-term investments of 
$15,572,000 discussed above in “Liquidity and Capital Resources,” while we used approximately $3,563,000 of short-term 
investments to finance our operations during 2017, including the cash costs of the Acquisition.  In addition (i) we used $40,000 
of cash for the purchase of a royalty on certain non-producing mineral leases in Montana during 2016 with no similar item 
during 2017; (ii) during 2017 we used $578,000 of the proceeds from the sale of Vendetta common stock to exercise the 
Vendetta Warrants, discussed above, compared the use of $304,000 of cash during 2016, which was primarily used to acquire 
the Vendetta units, consisting of Vendetta shares and the Vendetta Warrants; (iii) during 2017 we received $666,000 from the 
sale of Vendetta shares, discussed above, of which $578,000 was used to exercise the Vendetta Warrants, compared to proceeds 
of $56,000 in proceeds from the sale of marketable equity securities during 2016; and (iii) we received $53,000 during 2017 
from the sale of derivative instruments related to Kinross calls compared to $45,000 from the sale of Kinross calls during 2016.   

The net cash used in financing activities of $32,000 during 2017 and the net cash used in financing activities of 

$248,000 during 2016 were for the repurchase of common stock for cancellation, discussed above.  We do not anticipate the 
use of a significant amount of cash for the repurchase of shares during 2018. 

(f). Development Activities, Exploration Activities, Environmental Compliance and Contractual Obligations  

Development Activities 

As a result of the Mt Hamilton Transaction we no longer have any ongoing development activities.   

Exploration Activities 

A historically significant part of our business involves the review of potential property acquisitions and continuing 

review and analysis of properties in which we have an interest, to determine the exploration and development potential of the 
properties.  In analyzing expected levels of expenditures for work commitments and property payments, our obligations to 
make such payments fluctuate greatly depending on whether, among other things, we make a decision to sell a property 
interest, convey a property interest to a joint venture, or allow our interest in a property to lapse by not making the work 
commitment or payment required.  In acquiring many of our interests in mining claims and leases, we have entered into 
agreements, which generally may be canceled at our option.  We are often required to make minimum rental and option 
payments in order to maintain our interest in certain claims and leases.  Our net 2017 mineral and surface property rental and 
option payments, included in exploration expense, were $24,000.  Our 2018 total exploration property rentals and option 
payments for properties we own or operate are estimated to be approximately $322,000.  Assuming that our joint ventures 
continue in their current status and that we do not appreciably change our property positions on existing properties, we estimate 
that our joint venture partners will pay on our behalf, or reimburse us approximately $305,000 of these annual payments.  
These obligations are detailed below under “Contractual Obligations.”  In addition, we may be required to make further 
payments in the future if we elect to exercise our options under those agreements or if we enter into new agreements.    

Environmental Compliance 

We are subject to various federal, state and local environmental laws and regulations in the countries where we 

operate.  We are required to obtain permits in advance of initiating certain of our exploration activities, to monitor and report 
on certain activities to appropriate authorities, and to perform remediation of environmental disturbance as a result of certain of 
35 

 
 
 
 
 
 
 
 
 
 
our activities.  Historically, the nature of our activities of review, acquisition and exploration of properties prior to the 
establishment of reserves, which may include mapping, sampling, geochemistry and geophysical studies, as well as some 
limited exploration drilling, has not resulted in significant environmental impacts in the past.  We have historically carried on 
our required environmental remediation expenditures and activities, if any, concurrently with our exploration activities and 
expenditures.  The expenditures to comply with our environmental obligations are included in our exploration expenditures in 
the statement of operations and have not been material to our capital or exploration expenditures, and have not had a material 
effect on our financial position.  For the years ended December 31, 2017 and 2016, we have not capitalized any costs related to 
environmental control facilities.  We do not anticipate our exploration activities will result in any material new or additional 
environmental expenditures or liabilities in the near future.

The following discussion relates to an analysis of our anticipated property exploration plans as of December 31, 2017.  

Please also see Note 2, “Mineral Properties,” to the consolidated financial statements in Item 8, “Financial Statements and 
Supplementary Data,” and our discussion of our properties under Item 2, “Properties” of this Annual Report on Form 10-K for 
a more complete discussion of all of our mineral properties. 

Florida Canyon  

The Florida Canyon project (formerly known as the Bongará project) is an advanced-stage high-grade zinc project in 

Peru.  Based on extensive exploration and development work conducted to date, we believe the property has excellent potential 
to be developed into a mine over the next several years.  The project is held in a joint ventured between Nexa (61%) and 
Solitario (39%).   

Solitario and Nexa jointly completed a PEA in 2017 that incorporated a variety of Nexa-generated prefeasibility 
studies into the analysis.  The PEA evaluation included resource estimation, mining and processing recovery estimates, a 
preliminary mining and processing plan, infrastructure layout, environmental considerations and an economic analysis based on 
the certain base case parameters.  The PEA envisioned an underground mining operation with a 2,500 tonne per day floatation 
mill for processing, resulting in a 12.5 year mine life.  Concentrates would be trucked to Nexa’s Cajamarquilla zinc smelter 
facility in Lima Peru. 

The 2018 Florida Canyon work program includes the completion of the access road into the mineralized portion of the 

project area and permitting that will allow new underground tunneling, surface drilling and other activities associated with the 
future development of the project.  The terrain at Florida Canyon is steep and all previous project access supporting surface and 
underground work programs was conducted by helicopter.  The lack of road access restricted the scope of field activities to 
further advance the project.  With the completion of the road, heavy equipment will be able to enter the project area and allow 
feasibility related activities to proceed efficiently.  Important future activities that will be facilitated by the completion of the 
road are the construction of an underground tunnel into the Karen-Milagros high-grade zinc zone, detailed underground 
resource/reserve definition drilling, surface drilling designed to increase the project resources and additional feasibility-related 
studies.  Road work is scheduled to begin in May after the rainy season ends and continue until the road is completed.  

Lik project 

The Lik project is an advanced-staged high-grade zinc project.  The project is held in a joint venture between Teck 

American (50%) and Solitario (50%).  

36 

 
 
 
 
 
 
   
 
 
 
 
 
Zazu completed a PEA in 2014 that incorporated a variety of prefeasibility studies into the analysis.  These studies 

included resource estimation, mining and processing recovery estimates, a preliminary mining and processing plan, 
infrastructure layout, environmental considerations and an economic analysis based on the base case parameters.  The PEA 
envisioned an open pit mining operation with a 5,500 ton per day floatation mill for processing resulting in a nine-year mine 
life.  Concentrates would be handled through the DMTS road and port system that currently handles all concentrate produced 
by the nearby Red Dog zinc mine of Teck American.  A summary of metallurgical testing and mineral processing is provided 
below.  The PEA analyzed the Lik project as a stand-alone operation building its own independent processing, tailings and port 
facilities. 

Solitario and Teck American, our 50% joint venture partner, have agreed to jointly fund a gravity geophysical 
program, continue baseline environmental work for mine permitting previously initiated by Zazu, and rehabilitate the Lik camp 
for 2018.  The objective of the gravity survey is to test for sub-surface gravity anomalies that may be associated with zinc 
deposits similar in nature to other Red Dog district zinc deposits.  Any gravity anomalies that are delineated may be potentially 
drill tested in 2019.  The 2018 program represents the first Teck American-Solitario (Zazu) joint exploration effort since 
inception of the joint venture.  Teck American will manage the 2018 program, although Solitario will remain the manager of 
the joint venture. 

Royalty Properties 

The 40,500-hectare Yanacocha royalty property is located in northern Peru immediately north of Newmont Mining-

Buenaventura's Minera Yanacocha Mine, historically one of the largest gold mines in South America.  We acquired the 
property in 1993 and sold it to Newmont Mining Corporation in 2000 for $6.0 million retaining a sliding scale NSR royalty on 
the property that varies from two to five percent, depending on the price of gold.  In addition, we hold royalties on the Pedra 
Branca property in Brazil, certain non-producing mineral properties in Mexico and non-producing mineral properties in 
Montana.  We consider all of these royalty properties to be an early-stage exploration properties, and although we believe each 
may have good potential to host economic mineralization, we will not receive any royalties from any of these properties until 
such time as their owners develop and place into operation a mine on the properties covered by our royalty.  Accordingly, we 
cannot predict revenue from our royalties in the near future, if ever.     

Other Properties 

We have budgeted 2018 exploration expenditures of $792,000 for exploration and evaluation of existing and potential 
new acquisitions of properties primarily in Peru, and to a lesser extent in other regions of North and South America.  We expect 
to carry out limited exploration activities during 2018 utilizing our own employees and contract geologists.   

(h). Discontinued Projects 

During 2016, we closed our exploration office in Mexico.  Solitario recorded a mineral property write-down of 

$10,000 related to the Norcan and Aconchi properties during 2016.  During 2016, we abandoned our interest in our Canta 
Colorado property in Peru and recorded a mineral property write-down expense of $3,000 related to Canta Colorado.  In 
addition, we recorded a loss on other assets in Mexico of $14,000 related to the exit from its exploration activities in Mexico 
during 2016.  We had no mineral property impairments during 2017.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM 

To the Shareholders and Board of Directors  
Solitario Zinc Corp. 
Wheat Ridge, Colorado 

OPINION ON THE FINANCIAL STATEMENTS 

We  have  audited  the  accompanying  consolidated  balance  sheets  of  Solitario  Zinc  Corp.  (formerly  Solitario  Exploration  and 
Royalty  Corp.,  the  "Company")  as  of  December  31,  2017  and  2016,  and  the  related  consolidated  statements  of  income, 
comprehensive income, stockholders' equity, and cash flows, for each year in the two-year period ended December 31, 2017, and 
the related notes (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in 
all material respects, the financial position of the Company as of December 31, 2017 and 2016, and the results of its operations 
and its cash  flows  for each  year in the two-year period ended December 31, 2017, in conformity  with accounting principles 
generally accepted in the United States of America. 

BASIS FOR OPINION 

These financial statements are the responsibility of the Company's management. 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 Public Company 
Accounting Oversight Board (United States) ("PCAOB") and are required to be independent with respect to the Company in 
accordance  with  the  U.S.  federal  securities  laws  and  the  applicable  rules  and  regulations  of  the  Securities  and  Exchange 
Commission and the PCAOB. 

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

Our audits included performing procedures to assess the risks of material misstatement of the 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.

SOLITARIO ZINC CORP. 
NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 
For the years ended December 31, 2017 and 2016 

1. Business and Summary of Significant Accounting Policies 

Business and company formation 

Solitario Zinc Corp. (formerly Solitario Exploration & Royalty Corp., “Solitario,” “Company”) is an exploration stage 

company as defined in Industry Guide 7, as issued by the United States Securities and Exchange Commission (“SEC”).  
Solitario was incorporated in the state of Colorado on November 15, 1984 as a wholly-owned subsidiary of Crown Resources 
Corporation ("Crown").  In July 1994, Solitario became a publicly traded company on the Toronto Stock Exchange (the 
"TSX") through its initial public offering.  Solitario has been actively involved in mineral exploration since 1993.  Solitario’s 
primary business is to acquire exploration mineral properties or royalties and/or discover economic deposits on its mineral 
properties and advance these deposits, either on its own or through joint ventures, up to the development stage.  At that point, 
or sometime prior to that point, Solitario would likely attempt to sell its mineral properties, pursue their development either on 
its own, or through a joint venture with a partner that has expertise in mining operations, or create a royalty with a third party 
that continues to advance the property.  As a result of the Acquisition (defined below under “Recent Developments”), Solitario 
is now primarily focused on the acquisition and exploration of zinc-related exploration mineral properties.  In addition to 
focusing on its mineral exploration properties and the evaluation of mineral properties for acquisition or purchase of royalty 
interests, Solitario also evaluates potential strategic corporate transactions for the potential acquisition of new precious and 
base metal properties and assets with exploration potential or business combinations that Solitario determines to be favorable to 
Solitario.   

Solitario has recorded revenue in the past from the sale of mineral property, including the sale of its former interest in 

Mount Hamilton LLC (“MHLLC”) the owner of its former Mt. Hamilton project (the “Mt. Hamilton Transaction”), and joint 
venture property payments and the sale of a royalty on its former Mt. Hamilton project.  Revenues from the sale or joint 
venture of properties, although significant when they occur, have not been a consistent annual source of revenue and would 
only occur in the future, if at all, on an infrequent basis. 

Solitario currently considers its carried interest in the Florida Canyon project and its interest in the Lik project 

(acquired in the Acquisition) to be its core mineral property assets.  Solitario’s joint venture partner is expected to 
continue the development and furtherance of the Florida Canyon project and Solitario will monitor progress at Florida 
Canyon.  Solitario is currently evaluating the exploration and development plans for the Lik project.  

As of December 31, 2017, Solitario has significant balances of cash and short-term investments that Solitario 

anticipates using, in part, to further the development of the Lik project and to potentially acquire additional mineral 
property assets.  The fluctuations in precious metal and other commodity prices has contributed to a challenging 
environment for mineral exploration and development, which has created opportunities as well as challenges for the 
potential acquisition of early-stage and advanced mineral exploration projects or other related assets at potentially 
attractive terms.  

Financial reporting 

The consolidated financial statements include the accounts of Solitario and its wholly-owned subsidiaries. All 
significant intercompany accounts and transactions have been eliminated in consolidation.  The consolidated financial 
statements are prepared in accordance with accounting principles generally accepted in the United States of America 
("generally accepted accounting principles"), and are expressed in US dollars. 

Recent developments 

Purchase of Zazu 

On July 12, 2017, Solitario completed the acquisition of Zazu Metals Corp. (“Zazu”) pursuant to a definitive 
arrangement agreement between Solitario and Zazu (the "Arrangement Agreement") whereby Solitario agreed to acquire all of 
the issued and outstanding common shares of Zazu (the "Zazu Shares") by way of a statutory plan of arrangement (the 
"Arrangement") under the Canada Business Corporations Act (the “Acquisition”).  The Arrangement was approved by the 
Ontario (Canada) Superior Court of Justice on July 7, 2017.  Per the Arrangement, Solitario issued 19,788,177 shares of its 
common stock on July 12, 2017 in exchange for all of the issued and outstanding Zazu Shares, which represented 0.3572 

46 

 
 
 
 
 
 
 
 
 
 
 
 
shares of Solitario common stock for each outstanding Zazu Share.  Solitario granted stock options to acquire an aggregate of 
1,782,428 shares of Solitario common stock to Zazu option holders the (“Replacement Options”) in connection with the 
Acquisition.  The total purchase price of $16,110,000, recorded during the year ended December 31, 2017, is detailed below.  
Results of operations for Zazu are included in Solitario’s consolidated financial statements from the date of the Acquisition.

The Acquisition was treated as an asset purchase in accordance with Accounting Standards Update (“ASU”) No. 
2017-01, “Business Combinations,” (“ASU 2017-01”).  Solitario adopted the provisions of ASU 2017-01 during the year 
ended December 31, 2017, which provides guidance on the classification of the treatment of business acquisitions as either the 
purchase of an asset or the purchase of a business.  See “Recent Accounting Pronouncements, below.  Accordingly, as the 
purchase of an asset (essentially the interest in the Lik project in Alaska) Solitario capitalized related transaction costs 
associated with the Acquisition, including the following costs:

The cash transaction costs less the cash acquired are shown as the cash transaction costs for the year ended December 

31, 2017 on the consolidated statement of cash flows. Solitario also incurred stock issuance costs of $117,000, related to the 
Acquisition, which were charged to equity.  

Name Change to Solitario Zinc Corp. 

Solitario shareholders voted at an annual meeting of shareholders held on June 29, 2017 in favor of an amendment to 

Solitario’s Articles of Incorporation to change Solitario’s name to “Solitario Zinc Corp.” from “Solitario Exploration & 
Royalty Corp.”  The name change was subject to the completion of the Acquisition and became effective on July 17, 2017.   

Convertible Debenture Financing 

On April 26, 2017, concurrent with the signing of the Arrangement Agreement, Solitario provided Zazu interim debt 

financing through a secured convertible debenture issued by Zazu in the principal amount of US$1.5 million (the "Debenture").  
Upon completion of the Acquisition, the Debenture, including accrued interest, was cancelled.  

Revenue recognition 

47 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Solitario records delay rental payments as revenue in the period received.  Any payments received for the sale of 

property interests are recorded as a reduction of the related property's capitalized cost.  Proceeds which exceed the capitalized 
cost of the property without reserves are recognized as revenue.  Payments received on the sale of properties with reserves are 
recognized as revenue to the extent the proceeds exceed the proportionate basis in the assets sold.  There were no delay rental 
payments in either 2017 or 2016.   

Use of estimates 

The preparation of financial statements in conformity with generally accepted accounting principles requires 

management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of 
contingent assets and liabilities at the date of the financial statements and the reported amounts of revenues and expenses 
during the reporting period.  Actual results could differ from those estimates.  Some of the more significant estimates included 
in the preparation of Solitario's financial statements pertain to: (i) Solitario’s carrying value of short-term investments; (ii) the 
recoverability of mineral properties related to its mineral exploration properties and their future exploration potential; (iii) the 
fair value of stock option grants to employees; (iv) the ability of Solitario to realize its deferred tax assets; and (v) Solitario's 
investment in marketable equity securities.   

In performing its activities, Solitario has incurred certain costs for mineral properties.  The recovery of these costs is 
ultimately dependent upon the sale of mineral property interests or the development of economically recoverable ore reserves 
and the ability of Solitario to obtain the necessary permits and financing to successfully place the properties into production, 
and upon future profitable operations, none of which is assured. 

Cash and cash equivalents  

Cash equivalents include investments in highly liquid money-market securities with original maturities of three 

months or less when purchased.  As of December 31, 2017, approximately $168,000 of Solitario’s cash and cash equivalents 
are held in brokerage accounts and foreign banks, which are not covered under the Federal Deposit Insurance Corporation 
(“FDIC”) rules for the United States.   

Short-term investments 

As of December 31, 2017, Solitario has $10,395,000 of Solitario’s current assets in United States Treasury securities 

(“USTS”) with maturities of 15 days to eighteen months.  The USTS are recorded at their fair value, based upon quoted market 
prices.  As of December 31, 2017 Solitario has  $1,247,000 in separate bank certificates of deposit (“CDs”) each with a 
maximum value of $250,000, and each of which are covered by Federal Deposit Insurance Corporation insurance to the full 
face value of the CDs.  At December 31, 2017, the CDs have maturities of between seven and fifteen months. Solitario’s short-
term investments are recorded at their fair value, based upon quoted market prices.  The short-term investments are highly 
liquid and may be sold in their entirety at any time at their quoted market price and are classified as a current asset.   

 Mineral properties   

Solitario expenses all exploration costs incurred on its mineral properties prior to the establishment of proven and 

probable reserves through the completion of a feasibility study.  Initial acquisition costs of its mineral properties are 
capitalized.  Solitario regularly performs evaluations of its investment in mineral properties to assess the recoverability and/or 
the residual value of its investments in these assets.  All long-lived assets are reviewed for impairment whenever events or 
circumstances change which indicate the carrying amount of an asset may not be recoverable, utilizing established guidelines 
based upon undiscounted future net cash flows from the asset or upon the determination that certain exploration properties do 
not have sufficient potential for economic mineralization.   

Derivative instruments 

Solitario accounts for its derivative instruments in accordance with ASC 815, "Accounting for Derivative Instruments 

and Hedging Activities" (“ASC 815”).  Solitario acquired its investment in Vendetta Mining Corp. (“Vendetta”) units, 
including the Vendetta Warrants (defined below) during 2016.  During 2017, Solitario exercised all of its Vendetta Warrants 
and at December 31, 2017 has no Vendetta Warrants.  Solitario classified the Vendetta Warrants as derivative instruments 
under ASC 815 and recorded the Vendetta Warrants at their fair value as other assets on the consolidated balance sheet at 
December 31, 2016.  Changes in fair value of the Vendetta Warrants are recognized in the statement of operations in the period 
of change as gain or loss on derivative instruments.  Solitario has entered into covered calls from time to time on its investment 
48 

 
 
 
 
 
 
 
 
 
 
           
 
 
in Kinross marketable equity securities.  Solitario has not designated its covered calls as hedging instruments and any changes 
in the fair value of the covered calls and its warrants are recognized in the statement of operations in the period of the change 
as gain or loss on derivative instruments.   

Fair value 

FASB ASC 820, “Fair Value Measurements and Disclosures” (“ASC 820”) establishes a framework for measuring 
fair value and requires enhanced disclosures about fair value measurements. ASC 820 clarifies that fair value is an exit price, 
representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction between 
market participants.  For certain of Solitario's financial instruments, including cash and cash equivalents and accounts payable, 
the carrying amounts approximate fair value due to their short-term maturities. Solitario's short-term investments in USTS and 
CDs, its marketable equity securities and any covered call options against those marketable equity securities are carried at their 
estimated fair value based on quoted market prices.  Solitario’s investment in the Vendetta Warrants, at December 31, 2016 
was carried at fair value as determined by a Black-Scholes model.  See Note 7, “Fair Value of Financial Instruments,” below.     

Marketable equity securities 

Solitario's investments in marketable equity securities are classified as available-for-sale and are carried at fair value, 

which is based upon quoted prices of the securities owned.  Solitario records investments in marketable equity securities as 
available-for-sale for investments in publicly traded marketable equity securities for which it does not exercise significant 
control and where Solitario has no representation on the board of directors of those companies and exercises no control over 
the management of those companies.  The cost of marketable equity securities sold is determined by the specific identification 
method.  Changes in fair value are recorded in accumulated other comprehensive income (loss) within shareholders' equity, 
unless a decline in fair value is considered other than temporary, in which case the decline is recognized as a loss in the 
consolidated statements of operations.   

Foreign exchange 

The United States dollar is the functional currency for all of Solitario's foreign subsidiaries.  Although Solitario's 

South American exploration activities during 2017 and 2016 were conducted primarily in Peru, a portion of the payments for 
the land, leasehold and exploration agreements as well as certain exploration activities are denominated in United States 
dollars. Foreign currency gains and losses are included in the results of operations in the period in which they occur.   

Income taxes 

Solitario accounts for income taxes in accordance with ASC 740, “Accounting for Income Taxes” (“ASC 740”).  

Under ASC 740, income taxes are provided for the tax effects of transactions reported in the financial statements and consist of 
taxes currently due plus deferred taxes related to certain income and expenses recognized in different periods for financial and 
income tax reporting purposes.  Deferred tax assets and liabilities represent the future tax return consequences of those 
differences, which will either be taxable or deductible when the assets and liabilities are recovered or settled.  Deferred taxes 
are also recognized for operating losses and tax credits that are available to offset future taxable income and income taxes, 
respectively.  A valuation allowance is provided if it is more likely than not that some portion or all of the deferred tax assets 
will not be realized. 

Accounting for uncertainty in income taxes  

ASC 740 clarifies the accounting for uncertainty in income taxes recognized in a company's financial statements. ASC 
740 prescribes a recognition threshold and measurement attribute for the financial statement recognition and measurement of a 
tax position taken or expected to be taken in a tax return. ASC 740 also provides guidance on derecognition, classification, 
interest and penalties, accounting in interim periods, disclosure, and transition. ASC 740 provides that a company's tax position 
will be considered settled if the taxing authority has completed its examination, the company does not plan to appeal, and it is 
remote that the taxing authority would reexamine the tax position in the future. These provisions of ASC 740 had no effect on 
Solitario's financial position or results of operations. See Note 5, “Income Taxes,” below. 

Earnings per share 

The calculation of basic and diluted earnings (loss) per share is based on the weighted average number of shares of 

common stock outstanding during the years ended December 31, 2017 and 2016.  Potentially dilutive shares, consisting of 

49 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
outstanding common stock options for 1,982,428 Solitario common shares, were excluded from the calculation of diluted 
earnings (loss) per share for the year ended December 31, 2017 because the effects were anti-dilutive.  There were no similar 
potentially dilutive option securities outstanding at December 31, 2016, and accordingly there were no effects of potentially 
dilutive shares for the year ended December 31, 2016.   

Employee stock compensation and incentive plans 

Solitario classifies all of its stock options as equity options in accordance with the provisions of ASC 718, 

“Compensation – Stock Compensation.”  See Note 9, “Employee Stock Compensation Plans,” below.   

Recent accounting pronouncements 

In May 2014, the FASB issued Accounting Standards Update ("ASU") 2014-09, Revenue from Contracts with 
Customers (Topic 606), (“ASU No. 2014-09”), which amended the existing accounting standards for revenue recognition. ASU 
No. 2014-09 establishes principles for recognizing revenue upon the transfer of promised goods or services to customers, in an 
amount that reflects the expected consideration received in exchange for those goods or services. In July 2015, the FASB 
deferred the effective date for annual reporting periods beginning after December 15, 2017.   The amendments may be applied 
retrospectively to each prior period (full retrospective) or retrospectively with the cumulative effect recognized as of the date of 
initial application (modified retrospective). Solitario will adopt ASU 2014-09 in the first quarter of 2018 and apply the full 
retrospective approach and does not expect the impact on its consolidated financial statements to be material. 

In February 2016, the FASB issued ASU 2016-02, “Leases” (“ASU No. 2016-02”), which will require lessees to 

recognize a right-of-use asset and a lease liability for all leases that are not short-term in nature. For a lessor, the accounting 
applied is also largely unchanged from previous guidance. The new rules will be effective for Solitario in the first quarter of 
2019. Solitario does not anticipate early adoption. Solitario does not expect the adoption of ASU No. 2016-02 to materially 
change its current accounting methods and therefore it does not expect the adoption to have a material impact on its 
consolidated financial position or results of operations. 

In January 2016 the FASB issued ASU No 2016-01, Financial Instruments – Recognition and Measurement of 

Financial Assets and Financial Liabilities (Topic 825) (“ASU No. 2016-01”).  ASU No. 2016-01 revises the classification and 
measurement of investment in certain equity investments and the presentation of certain fair value changes for certain financial 
liabilities measured at fair value.  ASU No. 2016-01 requires the change in fair value of many equity investments to be 
recognized in net income.  ASU No. 2016-01 is effective for interim and annual periods beginning after December 15, 2017, 
with early adoption permitted.  Solitario will adopt ASU No. 2016-01 in the first quarter of 2018 which may result in a 
cumulative effect adjustment to the consolidated statement of equity retained earnings as of the beginning of the year in 2018.  
Solitario is evaluating the new guidance and has not determined the impact of ASU No. 2016-01 on its consolidated financial 
statements.   

In March 2016, the FASB issued Accounting Standards Update (“ASU”) 2016-09, “Compensation—Stock 

Compensation (Topic 718): Improvements to Employee Share-Based Payment Accounting” (“ASU 2016-09”), which 
simplifies several aspects of the accounting for share-based payment award transactions including accounting for income taxes 
and classification of excess tax benefits on the statement of cash flows, forfeitures and minimum statutory tax withholding 
requirements. ASU 2016-09 is effective for annual periods beginning after December 15, 2016, and interim periods within 
those annual periods. The adoption of ASU 2016-09 in 2017 did not materially change the Solitario’s previous accounting 
methods and therefore did not have a material impact on Solitario’s consolidated financial position or results of operation.  

On January 5, 2017, the Financial Accounting Standards Board issued ASU 2017-01. ASU 2017-01 clarified the 

definition of the acquisition of a business or an asset under Accounting Codification Standard 805 (“ASC 804”).  ASU 2017-10 
utilizes a series of tests or screens to determine if a business combination is the acquisition of a single identifiable asset or of a 
business.  Under the definition of ASU 2017-01, the Acquisition would fall under the classification of the acquisition of an 
asset.  ASU 2017-01 is effective for fiscal years beginning after December 15, 2017, with early adoption permitted.  Solitario 
adopted the provisions of ASU 2017-01 during 2017, and has accounted for the Acquisition in accordance with the provisions 
of ASU 2017-01.  The adoption of ASU 2017-01 had no other effect on Solitario’s consolidated financial position.  

In February 2018, the FASB issued ASU No. 2018-02, “Reclassification of Certain Tax Effects from Accumulated 

Other Comprehensive Income.”  ASU 2018-02 allows for a reclassification from accumulated other comprehensive income or 
loss to retained earnings or accumulated deficit for stranded tax effects resulting from the Tax Cuts and Jobs Act of 2017 

50 

 
 
 
 
 
 
 
 
 
(“TCJA”). ASU 2018-02 also requires certain related disclosures. ASU 2018-02 is effective for annual periods, and interim 
periods within those annual periods, beginning after December 15, 2018 and should be applied either in the period of adoption 
or retrospectively to each period in which the effect of the change in the U.S. federal corporate income tax rate in the TCJA is 
recognized. Early adoption is permitted. The Solitario is currently evaluating the impact of ASU 2018-02 but does not believe it 
will have a material effect on the Solitario’s financial position or results of operations.

Solitario's exploration mineral properties at December 31, 2017 and 2016 consist of use rights related to its 

exploration properties, and the value of such assets is primarily driven by the nature and amount of economic mineral ore 
believed to be contained, or potentially contained, in such properties.  The amounts capitalized as mineral properties include 
concession and lease or option acquisition costs.  Capitalized costs related to a mineral property represent its fair value at the 
time it was acquired.  At December 31, 2017, none of Solitario’s exploration properties have production (are operating) or 
contain proven or probable reserves.  Solitario's exploration mineral properties represent interests in properties that Solitario 
believes have exploration and development potential.  Solitario's mineral use rights generally are enforceable regardless of 
whether proven and probable reserves have been established.  Solitario acquired the Lik project during 2017 in the Acquisition; 
see Note 1 “Recent Developments” above.    

In addition to its capitalized exploration properties, Solitario has an interest in its Florida Canyon exploration 

concession, which is currently subject to a joint venture agreement where joint venture partners made stand-by joint venture 
payments to Solitario prior to January 1, 2015.  Solitario recorded joint venture property payment revenue received in excess of 
capitalized costs.  Per the joint venture agreement, as of December 31, 2017, no further standby joint-venture payments are due 
to Solitario on the Florida Canyon project.  At December 31, 2017 and 2016, Solitario has no remaining capitalized costs 
related to its Florida Canyon joint venture.   

Solitario previously sold its mineral interests in its Yanacocha exploration projects and retained a royalty interest.  

Solitario has no capitalized costs related to its Yanacocha royalty interest.  During the year ended December 31, 2016, Solitario 
acquired certain net smelter royalties on non-producing exploration leases in Montana previously owned by Atna Resources, 
Ltd. for $40,000. 

Discontinued projects  

During 2017, Solitario abandoned its interests in the Aconchi and Norcan exploration properties in Mexico and 

Solitario no longer holds any interest in those properties.  However, there were no capitalized mineral property costs related to 
these properties and Solitario did not record any mineral property write-downs during the year ended December 31, 2017.   

During 2016, Solitario closed its exploration office in Mexico.  Solitario recorded a mineral property write-down of 
$10,000 related to the Norcan and Aconchi properties during 2016.  During 2016, Solitario abandoned its interest in its Canta 
Colorado property in Peru and recorded a mineral property write-down expense of $3,000 related to Canta Colorado.  In 
addition, Solitario recorded a loss on other assets in Mexico of $14,000 related to the cessation of its exploration activities in 
Mexico during 2016.

including certain drill sites and access roads at the camp.  The estimate was based upon estimated cash costs for reclamation as 
determined by the permitting bond required by the State of Alaska, for which Solitario has purchased a reclamation bond 
insurance policy in the event Solitario or its 50% partner, Teck, do not complete required reclamation.  

Solitario has not applied a discount rate to the recorded asset retirement obligation as the estimated time frame for  
reclamation is not currently known, as reclamation is not expected to occur until the end of the Lik project life, which would 
follow future development and operations, the start of which cannot be estimated or assured at this time.  Additionally, no 
depreciation will be recorded on the related asset for the asset retirement obligation until the Lik project goes into operation, 
which cannot be assured. 

3. Marketable Equity Securities 

On May 2, 2016, Solitario purchased 7,240,000 units of Vendetta for aggregate consideration of $289,000.  Each unit 

included one common share of Vendetta and one purchase warrant which allow the holder to purchase one share of Vendetta 
common stock at a price of Cdn$0.10 per share for a period of two years (the “Vendetta Warrants”).  The purchase price of the 
units of $289,000 was allocated between the Vendetta common shares and the Vendetta Warrants based upon total fair values 
on the date of purchase.  The Vendetta common stock was allocated a purchase cost of $186,000 and the Vendetta Warrants 
were allocated a purchase cost of $103,000.   As discussed below, during 2017 Solitario exercised all of its Vendetta Warrants, 
and sold 3,480,000 shares of Vendetta common stock.  As of December 31, 2017, Solitario owns 11,000,000 shares of 
Vendetta common stock which are carried at their fair value based upon the quoted market price of Vendetta, a publicly traded 
company on the TSX venture exchange, and included in marketable equity securities.  .

During 2017, Solitario sold 3,480,000 Vendetta common shares, for cash proceeds of $666,000.  In addition, during 

2017, Solitario exercised its Vendetta Warrants, also discussed below in Note 4, “Other assets” and received 7,240,000 
common shares of Vendetta.  Solitario transferred the fair value of the Vendetta Warrants on the date of exercise of $949,000, 
along with the cash paid to exercise the Vendetta Warrants of $578,000 to marketable equity securities as the cost of the 
7,240,000 common shares of Vendetta acquired.

During 2017, Solitario acquired $100,000 of exploration-related equipment at the Lik project as part of the 

Acquisition. See Note 1, “Recent developments’” above.  The equipment is being depreciated over a five-year life on a straight-
line basis and Solitario recorded depreciation expense of $10,000 during 2017 related to this equipment. 

During 2017, Solitario exercised 7,240,000 of its Vendetta Warrants and received 7,240,000 Vendetta common shares, 

by paying $578,000 in cash to Vendetta.  As a result, as of December 31, 2017, Solitario no longer owns any Vendetta 
Warrants.  Upon the exercise of the Vendetta Warrants, Solitario transferred the fair value of the Vendetta Warrants on the date 
of exercise of $949,000 along with the cash paid to exercise the Vendetta Warrants of $578,000 to marketable equity securities 
as the cost of the 7,240,000 common shares of Vendetta acquired.  During the year ended December 31, 2017 and 2016, 
Solitario recorded a gain on derivative instruments of $216,000 and $629,000, respectively, related to the Vendetta Warrants; 
see Note 6, “Derivative Instruments,” below.

On December 22, 2017, the Tax Cuts and Jobs Act of 2017 (the “Tax Act”) was signed into law making significant 

changes to the Internal Revenue Code.  Changes include, but are not limited to, a federal corporate tax rate decrease from 35% 
to 21% for tax years beginning after December 31, 2017, the transition of U.S international taxation from a worldwide tax 

54 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
system to a territorial system, and a one-time transition tax on the mandatory deemed repatriation of foreign earnings. Solitario 
estimated its provision for income taxes in accordance with the Tax Act and guidance available as of the date of this filing.  In 
accordance with ASC 740, Income Taxes, the impact of a change in tax law is recorded in the period of 
enactment.  Consequently, Solitario has recorded a decrease to its net deferred tax assets of $4,494,000 with a corresponding 
net adjustment to the valuation allowance for the year ended December 31, 2017.   

While the Tax Act provides for a territorial tax system, beginning in 2018, it includes two new U.S. tax base erosion 

provisions, the global intangible low-taxed income (“GILTI”) provisions and the base-erosion and anti-abuse tax (“BEAT”) 
provisions. 

The GILTI provisions require the Company to include in its U.S. income tax return foreign subsidiary earnings in 
excess of an allowable return on the foreign subsidiary’s tangible assets.  The Company currently has no profitable foreign 
subsidiaries.  Therefore, this provision currently has no impact on the Company. 

The BEAT provisions in the Tax Act eliminates the deduction of certain base-erosion payments made to related 

foreign corporations, and impose a minimum tax if greater than regular tax. The Company does not expect it will be subject to 
this tax and therefore has not included any tax impacts of BEAT in its consolidated financial statements for the year ended 
December 31, 2017. 

Based on Solitario’s current interpretation and subject to the release of the related regulations and any future 

interpretive guidance, Solitario believes the effects of the change in tax law incorporated herein are substantially 
complete. Additional information that may affect our income tax accounts and disclosures would include further clarification 
and guidance on how the Internal Revenue Service will implement tax reform, further clarification and guidance on how state 
taxing authorities will implement tax reform and the related effect on our state income tax returns, completion of our 2017 tax 
return filings, and the potential for additional guidance from the FASB and SEC related to tax reform. 

As a result of the acquisition of Zazu Metals Corporation, Solitario acquired deferred tax assets totaling $11,202,000 

primarily related to US federal and state net operating losses, mineral properties and exploration costs, and Canadian net 
operating losses.  These deferred tax assets were fully offset by a valuation allowance, as the Solitario does not believe it is 
more likely than not that the assets will be utilized in the future. As a result of the ownership change of Zazu Metals (Alaska) 
Corp, utilization of its United States Federal and State of Alaska net operating losses will be limited due to the annual 
limitation provided by Section 382 of the Internal Revenue Code. 

During 2017, the valuation account was increased primarily due to the acquisition of Zazu Metals Corporation and the 

impact of the Tax Act.  During 2016, the valuation allowance was decreased primarily due to the removal of deferred tax assets 
related to abandoned properties in Mexico.   

During 2017 and 2016, Solitario recorded other comprehensive (loss) income before income tax in the amounts of 
$(136,000) and $954,000, respectively.  In 2017 and 2016 Solitario recognized an income tax benefit (expense) of nil and 
$(353,000), respectively, in other comprehensive income (loss) with an offsetting income tax expense (benefit), respectively in 
the statement of operations. A valuation allowance was provided for the deferred tax assets from losses in both other 
comprehensive income and the statement of operations during 2017. 

At December 31, 2017, Solitario has unused US Federal Net Operating Loss ("NOL") carryovers of $10,914,000 and 

unused US State NOL carryovers of $11,338,000 which begin expiring in 2027.  Solitario has unused Capital Loss carryovers 
of $11,879,000 for US Federal and US State purposes which begin expiring in 2019. Solitario has Canadian loss carryforwards 
of $12,192,000 which begin expiring in 2026.  Other foreign loss carryforwards for which Solitario has provided a full 
valuation allowance related to Solitario’s exploration activities in Peru.  The Peru losses do not expire. 

Solitario adopted ASC 740, which prescribes a recognition threshold and measurement attribute for the financial 
statement recognition and measurement of a tax position taken or expected to be taken in a tax return. ASC 740 requires that 
Solitario recognize in its consolidated financial statements, only those tax positions that are “more-likely-than-not” of being 
sustained as of the adoption date, based on the technical merits of the position. As a result of the implementation of ASC 740, 
Solitario performed a comprehensive review of its material tax positions in accordance with recognition and measurement 
standards established by ASC 740.  The provisions of ASC 740 had no effect on Solitario’s financial position, cash flows or 
results of operations at December 31, 2017 or December 31, 2016, or for the years then ended as Solitario had no unrecognized 
tax benefits.    

55 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Solitario and its subsidiaries are subject to the following material taxing jurisdictions: United States Federal, State of 

Colorado, State of Alaska, Canada and Peru.  Solitario’s United States federal, Canada and State of Alaska returns for years 
2014 and forward and Solitario’s Peru and State of Colorado returns for tax years 2013 and forward are subject to examination.  
Solitario’s policy is to recognize interest and penalties related to uncertain tax benefits in income tax expense. Solitario has no 
accrued interest or penalties related to uncertain tax positions as of December 31, 2017, or December 31, 2016 or for the years 
then ended 

6. Derivative Instruments: 

Covered call options 

From time to time Solitario has sold covered call options against its holdings of Kinross. The business purpose of 

selling covered calls is to provide additional income on a limited portion of shares of Kinross that Solitario may sell in the near 
term, which is generally defined as less than one year.  Solitario has not designated its covered calls as hedging instruments as 
described in ASC 815, “Derivatives and Hedging,” and any changes in the fair value of its covered calls are recognized in the 
statement of operations in the period of the change.  As of December 31 2017, all of the covered calls had expired unexercised 
and there were no liabilities related to those calls entered during the year.  As of December 31, 2016, Solitario had two covered 
calls against its holdings of Kinross common stock, which had a fair value of $2,000.    

Vendetta Warrants 

All of the Vendetta Warrants were exercised during 2017 and there is no remaining asset value as of December 31, 

2017 for the Vendetta Warrants; see Note 4, “Other Assets” above.

For certain of Solitario's financial instruments, including cash and cash equivalents, payables and short-term debt, the 

carrying amounts approximate fair value due to their short maturities. Solitario's marketable equity securities, including its 
investment in shares of Kinross common stock, Vendetta common stock and TNR Gold Corp (“TNR”) common stock, are 
carried at their estimated fair value primarily based on publicly available quoted market prices.       

Solitario applies ASC 820, "Fair Value Measurements" (“ASC 820”).  ASC 820 establishes a framework for 
measuring fair value and requires enhanced disclosures about fair value measurements. ASC 820 clarifies that fair value is an 
exit price, representing the amount that would be received to sell an asset or paid to transfer a liability in an orderly transaction 
between market participants. ASC 820 also requires disclosure about how fair value is determined for assets and liabilities and 
establishes a hierarchy for which these assets and liabilities must be grouped, based on significant levels of inputs as follows:  

Level 1: Quoted prices in active markets for identical assets or liabilities; 
Level 2: Quoted prices in active markets for similar assets and liabilities and inputs that are observable for 
the asset or liability; or 
Level 3: Unobservable inputs in which there is little or no market data, which require the reporting entity to 
develop its own assumptions. 

The determination of where assets and liabilities fall within this hierarchy is based upon the lowest level of input that 

is significant to the fair value measurement.  During the years 

56 

 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
ended December 31, 2017 and 2016, there were no reclassifications in financial assets or liabilities between Level 1, 2 or 3 
categories.

Items measured at fair value on a recurring basis:  

Marketable equity securities: At December 31, 2017 and 2016, the fair value of Solitario’s holdings in shares of 
Vendetta, Kinross, and TNR marketable equity securities and the Kinross calls are based upon quoted market prices.   
Vendetta Warrants:  The Vendetta Warrants are not traded on any public exchange.  Solitario determines the fair value 
of the Vendetta Warrants using a Black-Scholes pricing model, using inputs, including share price, volatility of 
Vendetta common stock and discount rates that include an assessment of performance risk, that are readily available 
from public markets; therefore, they are classified as Level 2 inputs as of December 31, 2016. 

During the year ended December 31, 2017, Solitario did not change any of the valuation techniques used to measure 

its financial assets and liabilities at fair value. 

8. Commitments and Contingencies: 

In acquiring its interests in mineral claims and leases, Solitario has entered into lease agreements, which may be 

canceled at its option without penalty.  Solitario is required to make minimum rental and option payments in order to maintain 
its interests in certain claims and leases.  See Note 2, “Mineral Properties,” above.  Solitario estimates its 2018 property rentals 
and option payments, excluding certain earn-in payments discussed below, for properties Solitario owns or operate to be 
approximately $322,000.  Assuming that Solitario’s joint ventures continue in their current status and that Solitario does  not 
appreciably change its property positions on existing properties, approximately $305,000 of these annual payments are paid or 
are reimbursable to us by Solitario’s joint venture partners.  In addition, Solitario may be required to make further payments in 
the future if it elects to exercise its options under those agreements or if Solitario enters into new agreements.   

Solitario has recorded an asset retirement obligation of $125,000 related to its Lik project in Alaska.  See Note 2, 

“Mineral Properties,” above. 

Solitario leases office space under a non-cancelable operating lease for the Wheat Ridge, Colorado office which 

provides for total minimum annual rent payments of $43,000 through January of 2019.  

9. Employee Stock Compensation Plans:  

The 2006 Plan 

On June 27, 2006, Solitario's shareholders approved the 2006 Stock Option Incentive Plan (the “2006 Plan”).  Under 

the terms of the 2006 Plan, the Board of Directors reserved a total of 2,800,000 shares of Solitario common stock for the 
potential awards to directors, officers and employees with exercise prices equal to the market price of Solitario's common stock 
at the date of grant.  The 2006 Plan terminated on June 26, 2016, and in accordance with the terms of the 2006 Plan, no

an expiration date of June 21, 2021 and 40,000 options with an option price of Cdn$1.66 with an expiration date of August 14, 2019.  No consideration was 
given or received by the holders of the options to cancel the awards.   

During the years ended December 31, 2016, Solitario recorded $120,000, of stock option expense under the 2006 Plan 

for the amortization of the grant date fair value through the date of cancellation and for any unrecognized grant date fair value 
on the date of cancellation of each of its outstanding options with a credit to additional paid-in-capital. 

The 2013 Plan 

On June 18, 2013, Solitario’s shareholders approved the Solitario Resources Corporation Omnibus Stock Incentive 

Plan (the “2013 Plan”).  Under the terms of the 2013 Plan, a total of 1,750,000 shares of Solitario common stock are reserved 
for awards to Directors, officers, employees and consultants.  On June 29, 2017, Solitario shareholders approved an 
amendment to the 2013 Plan, which increased the number of shares of common stock available for issuance under the 2013 
Plan from 1,750,000 to 5,750,000.  Awards granted under the 2013 Plan may take the form of stock options, stock appreciation 
rights, restricted stock, and restricted stock units.  The terms and conditions of the awards are pursuant to the 2013 Plan and are

(1)Intrinsic value based upon December 31, 2017 price of a share of Solitario common stock as quoted on the NYSE American exchange of $0.60 
per share, with an exchange ratio (for Canadian priced options) of 0.79659 Cdn$/US$.  There were no options outstanding at December 31, 2016.  
(2) On August 24, 2016, holders of option awards from the 2013 Plan voluntarily cancelled awards for 1,699,000 options with an option price of 
$.072 with an expiration date of July 27, 2021 to allow Solitario to have additional financial flexibility.  No consideration was given or received by 
the holders of the options to cancel the awards.   

During the years ended December 31, 2017 and 2016, Solitario recorded $50,000 and $850,000, respectively, of stock 
option expense under the 2013 Plan for the amortization of the grant date fair value through the date of cancellation and for any 
unrecognized grant date fair value on the date of cancellation of each of its outstanding options with a credit to additional paid-
in-capital. 

On September 1, 2017, the Board of Directors granted, subject to shareholder approval at the next meeting of 

shareholders, an additional 2,300,000 stock options under the 2013 Plan to officers and members of the Board of Directors.  
These options have a five-year life, and exercise price of $0.77 per share, and a grant date fair value of $970,000, based upon a 
Black-Scholes model with a volatility of 64%, and a risk free interest rate of 1.70%.  Although the options will vest on the 
schedule of 25% on date of grant and 25% on each of the next three anniversary dates of the date of grant, the options will not 
become exercisable in whole or in part unless Solitario shareholders approve the grants, and the option grants will be void if 
Solitario shareholders do not approve the grants.  Solitario will not record any stock option expense related to these options 
until the shareholder approval is received.

purchase price of $32,000 and $248,000, respectively.  As of December 31, 2017, Solitario has purchased a total of 667,800 
shares for an aggregate purchase price of $348,000 under the share repurchase program since its inception.

Item 9A. Controls and Procedures 

The management of Solitario is responsible for establishing and maintaining adequate internal control over financial 

reporting (as defined in Rule 13a-15(e) of the Exchange Act).  During the fiscal period covered by this report, Solitario's 
management, with the participation of the Chief Executive Officer and Chief Financial Officer, carried out an evaluation of the 
effectiveness of Solitario’s internal control over financial reporting and the design and operation of Solitario’s disclosure 
controls and procedures (as defined in Rule 13a-15(e) of the Exchange Act). This evaluation of the effectiveness of our internal 
control over financial reporting was based on the framework and criteria established in Internal Control – Integrated 
Framework (2013), issued by the Committee of Sponsoring Organizations of the Treadway Commission.  Based on such 
evaluations, Solitario’s Chief Executive Officer and Chief Financial Officer have concluded that, as of December 31, 2017, 
Solitario’s internal control over financial reporting is effective and that its disclosure controls and procedures are effective to 
ensure that information required to be disclosed by Solitario in reports that it files or submits under the Exchange Act is 
recorded, processed, summarized and reported within the required time periods and are designed to ensure that information 
required to be disclosed in its reports is accumulated and communicated to Solitario’s management, including the Chief 
Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure.  There 
were no changes in internal control over financial reporting during the three months ended December 31, 2017. 

This Annual Report does not include an attestation report of our independent registered public accounting firm 

regarding internal control over financial reporting. As a smaller reporting company, Solitario’s management’s report was not 
subject to attestation by our independent registered public accounting firm pursuant to rules of the SEC that permit us to 
provide only management’s report in this annual report.
