Solitario Zinc Corp. Announces First Jointly Funded Work Program on the Lik Zinc Project, Alaska

DENVER, April 03, 2018 - Solitario Zinc Corp. ("Solitario" or "the Company") (NYSE American: XPL; TSX: SLR) is pleased to announce that Solitario, through its 100%-owned subsidiary Zazu Metals (50% Lik interest) and Teck American Incorporated ("Teck") (50% Lik interest), a wholly owned subsidiary of Teck Resources Limited, Canada's largest diversified resource company, (TSX: TECK.A and TECK.B, NYSE: TECK), have approved a jointly funded budget for a new work program on the Lik zinc project in Alaska. This is the first time that project work has been jointly funded, as previously, Zazu Metals, acquired by Solitario in July 2017, had sole-funded the project as part of an option earn-in agreement. Solitario believes this is a positive step for future exploration and development activities for the Lik project.

Potentially amenable to open pit mining, the Lik project hosts an Indicated Resource of approximately 17.3 million tonnes grading 8.0% zinc, 2.7% lead and 51 grams/tonne silver and an additional 2.9 million tonnes of Inferred Resource at 8.6% zinc, 2.6% lead and 37 grams/tonne silver (see Table 1). The project is situated approximately 14 miles northwest of Teck's operating Red Dog mine, one of the world's largest and lowest cost zinc mines.

To leverage Teck's thirty years of successful exploration and operational experience in the world-class Red Dog mining district, Solitario and Teck agreed that Teck will act as project operator for this program. The proposed work program, which will begin once appropriate permits are obtained, will consist of surface geologic, geophysical and environmental work, as well as Lik camp rehabilitation. Specific activities include:

- Geologic mapping of the property block to better understand the stratigraphy and structure of the property to aid in the development of drill targets.

- The geophysical program will consist of a new gravity survey over a substantial part of the 6,075-acre Lik property block. Other geophysical work consists of compilation and merging of past Induced Polarization geophysical surveys. Teck has had success in the greater Red Dog zinc district using geophysical tools to detect moderately to deeply buried zinc deposits.

- Relogging of Lik core will also be undertaken to compare and contrast the Lik deposit to deposits in other parts of the prolific Red Dog Zinc District.

- Camp rehabilitation to allow for future use of the established infrastructure.

- Assessment of previous environmental work to determine what additional studies are required as the project advances.

Chris Herald, President and CEO of Solitario, commented, "We clearly see project benefits in utilizing Teck's long-term experience in the Red Dog zinc district and are excited about working with Teck to advance the Lik project at a time of encouraging zinc and lead prices and supply-demand fundamentals. The 2018 work program is designed to be the first-step in identifying new drilling targets and assessing the path forward for project development."


The Lik Zinc-Lead Deposit

The Lik deposit is a large sediment-hosted zinc-lead-silver deposit in the Red Dog mining district. As presently defined, 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 open down-dip and to the north. A total of 125,300 feet of drilling in 229 holes has been completed on the Lik property to date. Drilling has defined the following resource:

Metallurgical Testing

Solitario conducted several metallurgical tests in late-2017 and early-2018 to investigate the potential for increasing Lik silver recoveries. Silver recoveries did not improve from previous test results that were used in the 2014 Lik PEA. This news release has been reviewed and approved by Walter H. Hunt, COO, and is a Non-Independent QP for Solitario under National Instrument 43-101.


Lik Joint Venture

The terms for a Lik joint venture were previously outlined in the Lik Block Agreement signed on January 27, 1983, between Houston Oil & Minerals Exploration Company ("Homex") and GCO Minerals Company. Through a series of third-party transactions, Teck currently holds Homex's 50% interest in the project, and Solitario owns GCO's 50% interest through its acquisition of Zazu Metals. Solitario and Teck are presently negotiating a new joint operating agreement that will update and clarify the original agreement and potentially modify its commercial terms.

Cautionary Note to U.S. Investors concerning estimates of Resources: This news release uses the terms "Measured, Indicated and Inferred Resources." The Company advises U.S. investors that while these terms are recognized and required by Canadian regulations, the SEC does not recognize the terms. U.S. investors are cautioned not to assume that any part or all of Measured or Indicated Mineral Resources will ever be converted into Reserves. Inferred Resources have a great amount of uncertainty as to their existence, and great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of an Inferred Mineral Resource will ever be upgraded to a higher category. Under Canadian rules, estimates of Inferred Mineral Resources may not form the basis of feasibility or pre-feasibility studies, except in rare cases. U.S. investors are cautioned not to assume that any part or all of a measured, indicated or inferred resource exists, or is economically or legally minable.


Cautionary Statement Regarding Forward Looking Information
