Telson Resumes Operations at Campo Morado Mine in Mexico

Vancouver, British Columbia, June 4, 2020

Telson Mining Corporation (“ Telson” or the “ Company” (TSX Venture Exchange-TSN, OTC Pink-SOHFF, Frankfurt-TSGN

(formerly SQ82)) is pleased to announce that mining and milling operations have resumed at Campo Morado mine in

Guerrero, Mexico. The Mexican Government recently deemed the mining industry to be an essential industry, resulting in

lifting of the temporary country wide mining industry shut down because of the COVID-19 pandemic.

Detailed COVID-19 safety protocols approved by the Instituto Mexicano del Seguro Social (“IMSS”) have been implemented

at the Campo Morado mine site to protect the health and safety of all our employees. These protocols include strict sanitary

measures, return-to-work health screenings and on-site medical personnel to monitor and respond to any health concerns.

Underground mining and processing activities re-commenced on June 3, 2020. Prior to the temporary suspension of

activities this last April, the mine was operating at an average production rate between 1,900 to 2,200 tons per day.

Additionally, the Company has about 2,900 tonnes of zinc concentrate, and 650 tonnes of lead concentrate currently stored

at the mine site and available for immediate shipping. The Company already started its shipping procedures to deliver its

concentrates to the point of sale at the port of Manzanillo.

“As a result of the Covid-19 pandemic, the past months have been very difficult for our organization and in general for

everyone all over the world.” States Ralph Shearing, CEO and President of Telson, “thankfully, there has been no COVID-19

reported infection to any of our Campo Morado employees or anyone at Telson. Additionally, with the strict health protocols

recently developed and implemented at Campo Morado mine site and throughout our organization, we are confident that

we will be able to maintain continuous mining operations at Campo Morado while minimizing the risk and exposure to

COVID-19 virus”

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 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, temporarily suspending operation during April and May 2020 as mandated by the Mexican

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. 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.
