Telson Closes Purchase of Nyrstar Variable Purchase Price Royalty at Campo Morado & Accelerates Construction at Tahuehueto

Campo Morado Royalty Purchase

Vancouver, British Columbia--(Newsfile Corp. - April 26, 2021) - Telson Mining Corporation (TSXV: TSN) (OTC Pink: SOHFF) (FSE: TSGN) ("Telson" or the "Company") is pleased to announce that the Company has closed the purchase of the Nyrstar Campo Morado Variable Purchase Price Royalty (the "VPP Royalty). Details of the transaction were previously announced on February 23, 2021. Telson has issued 14,600,000 shares at the negotiated price of C$0.345 per share, which was roughly a 64% premium to Telson's trading price as of Feb 22, 2021, the date the parties executed the VPP Royalty acquisition letter agreement.

Tahuehueto Update

Telson is also pleased to inform shareholders that last week construction work was accelerated at the Tahuehueto gold mine construction project where Telson is building a 1,000 tpd mining operation. Additional construction crews have arrived at the site and have re-commenced assembly work of the mineral processing facility and are preparing for the start of work on other major infrastructure initiatives such as the tailings storage facility, water pumping station and the water line which will supply the necessary water to sustain continuous milling and mining operations.

Tahuehueto capital expenditure ("CAPEX") investment required to complete mine construction and commissioning of the project is estimated at US$15.4 million. This includes US$12.6 million for equipment and construction including a 15% contingency, plus US$2.8 million of working capital to support the operations until the mine has achieved positive cash flow.

To date Telson, on March 30, 2021, closed a C$10,080,000 private placement and last week, on April 16, 2021 executed the Empress Silver Stream agreement that will provide an additional US $5 million in two tranches of capital to Tahuehueto construction. The final US $12 million Accendo Banco loan facility is in the late stages of documentation and expected to close in the coming weeks along with the restructuring of Telson outstanding loans with Trafigura and Nyrstar.

"The closing of the VPP Royalty is a major positive step for Telson and the Campo Morado Mine and will increase revenue at Campo Morado on an ongoing basis. To put this into context, at average March 2021 realized zinc sale prices, purchasing the VPP Royalty, that would have been at its highest variable rate of 4.25% on the production of zinc, Telson has realized additional revenue of over US$450,000 for March 2021 production." states Ralph Shearing, Telson's President and CEO. "This along with accelerating our Tahuehueto construction should be welcome news to our shareholders and investors."

Cautionary Note Regarding Production Decisions and Forward-Looking Statements

It should be noted that Telson declared commercial production at Campo Morado prior to completing a feasibility study of mineral reserves demonstrating economic and technical viability. Accordingly, readers should be cautioned that Telson's production decision has been made without a comprehensive feasibility study of established reserves such that there is greater risk and uncertainty as to future economic results from the Campo Morado mine and a higher technical risk of failure than would be the case if a feasibility study were completed and relied upon to make a production decision. Telson has completed a preliminary economic assessment ("PEA") mining study on the Campo Morado mine that provides a conceptual life of mine plan and a preliminary economic analysis based on the previously identified mineral resources (see News Release dated November 8, 2017 and April 4,2018).

In certain cases, Forward-Looking Information can be identified using words and phrases such as "plans," "expects," "scheduled," "estimates," "forecasts," "intends," "anticipates" or variations of such words and phrases.
