Estimated revenues for Q1 2021, net of all concentrate sale deductions such as treatment charges, penalties, etc., were approximately US$11.9M (final revenue figures are subject to review and agreement of final assay results), representing a 35% increase versus the previous quarter. C1 cash costs, all-in sustaining cost per pound and other operational financial details will be disclosed in the company's upcoming quarterly financial statements which are due to be filed on or before May 31, 2021.

Ralph Shearing, Telson CEO and President, stated "These strong first quarter results continue to reflect our steady progression of improving the throughput and recoveries at Campo Morado. To this end, management intends to initiate a rigorous metallurgical testing program to advance through second phase testing the Leachox Process of Maelgwyn Mineral Services and the Albion Process of Core Group, both of which returned positive test results in first phase testing. This metallurgical testing program will also study the ability to increase base metal recoveries at microfine grinding with flotation recovery using Imhoflot Flotation and Jamison Cell flotation technologies both designed for such purposes. We are confident that additional recovery improvements are available utilizing these exciting modern technologies which, if successful can provide increased revenue streams."

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 working 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 closing its recently announced US$25 million funding package (see press release dated February 23, 2021)

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. 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 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 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.
