It is recognized that a breach of the Letter Agreement shall not have occurred should Telson fail to receive the letters of intent and binding offers as contemplated in the above sections as a result of market conditions which fail to generate bona fide interest in the purchase of the assets so long as Telson has in good faith made all commercially reasonable efforts to advance the Transaction and can provide evidence of such efforts.

"Telson is very pleased to have received the cooperation of Trafigura in the negotiations to finalize the Letter Agreement thereby obtaining Trafigura's waiver to a default under the Loan Agreements", stated Ralph Shearing, Telson's President & CEO, "the additional time now available of just under 16 months for our Company to repay our loan debt to Trafigura, will allow Telson a reasonable time frame to achieve funding and finish construction of its robust 100% owned flagship asset, the Tahuehueto gold mine project"

About Telson Mining Corporation located

Telson Mining Corp. is a Canadian based mining company with two 100% owned Mexican gold, silver and base metal mining projects.

Telson's Tahuehueto mining project, located in north-western Durango State, Mexico where construction has been advanced to approximately 70% completion and waiting for final funding to finish construction of the processing plant and related assets to produce gold, silver, lead and zinc in concentrates within its own on-site mineral processing facility, with a designed capacity of at least 1,000 tonnes per day. The Company is targeting completion of construction during 2021, six to eight months after securing final funding.

Campo Morado is a polymetallic base metal mine with mining and milling equipment capable of producing up to 2,500 tonnes per day. Four months after purchasing Campo Morado, Telson brought the mine back into operation initiating preproduction in October 2017 and declared commercial production in May 2018, operating the mine continuously for 22 months until August 2019 when the project was put on care and maintenance as a result of declining zinc prices and community issues. Telson brought the mine out of care and maintenance and reinitiated mining and milling operations during late January 2020.

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 was 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).

Statements contained in this news release that are not historical facts are "forward-looking information" or "forward-looking statements" (collectively, "Forward-Looking Information") within the meaning of applicable Canadian securities laws. Forward Looking Information includes, but is not limited to, disclosure regarding the planned recommencement of mining operations at Campo Morado; the ability to recommence outstanding payments to Nyrstar; and other possible events, conditions or financial performance that are based on assumptions about future economic conditions and courses of action; the timing and costs of future activities on the Company's properties, such as production rates and increases; success of exploration, development and bulk sample processing activities, and timing for processing at its own mineral processing facility on the Tahuehueto project site. In certain cases, Forward-Looking Information can be identified by the use of words and phrases such as "plans", "expects", "scheduled", "estimates", "forecasts", "intends", "anticipates" or variations of such words and phrases. In preparing the Forward-Looking Information in this news release, the Company has applied several material assumptions, including, but not limited to, that the current exploration, development, environmental and other objectives concerning the Campo Morado Mine and the Tahuehueto Project can be achieved; that recommencement of operations at Campo Morado will proceed as planned; that discussions with Nyrstar and the abeyance of any potential default proceedings will be completed in a timely manner and on reasonable terms, the continuity of the price of gold and other metals, economic and political conditions and operations. Forward-Looking Information involves known and unknown risks, uncertainties and other factors which may cause the actual results, performance or achievements of the Company to be materially different from any future results, performance or achievements expressed or implied by the Forward-Looking Information. There can be no assurance that Forward-Looking Information will prove to be accurate, as actual results and future events could differ materially from those anticipated in such statements.
