About Telson Mining Corporation

Telson Mining Corporation 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 is 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, eight to twelve months after securing final funding.

Campo Morado is a polymetallic base metal mine with mining and milling equipment currently producing at an average of

approximately 2,150 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 . With improving current conditions Telson brought the mine out of care and

maintenance and reinitiated mining and milling operations during 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 c ompleted

and relied upon to make a production decision. Telson has complete d 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; and other

possible events, conditions or financial performance that are based on assumptions about future economic conditi ons and courses of

development and bulk sample processing activities, and timing for processing at its own minera l 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 t he 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; 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 anticip ated
