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 ), repre-

senting a 35% increase versus the previous quarter . C1 cash costs, all-in sustaining cost per pound and other opera-

tional 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 ref lect our steady pro-

gression of improving the throughput and recover ies at Campo Morado. To this end, management intends to initiate a rig-

orous 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 metal-

lurgical 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 com-

pletion of construction during 2021, six to eight months after closing its recently a nnounced 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 aver-

age of approximately 2,150 tonnes per day. Four months afte r 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 mainte-

nance. 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 secur ities 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 abou t 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 pro cessing 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 new s 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; 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 a ny

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. Accordingly, readers should not place undue reliance on Forward-Looking Information. Except as required by law, the

Company does not assume any obligation to release publicly any revisions to Forward-Looking Information contained in this news release

to reflect events or circumstances after the date hereof or to reflect the occurrence of unanticipated events.
