Telson Mining Corp. Resumes Operations at Campo Morado Mine in Mexico

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 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, temporarily suspending operation during April and May 2020 as mandated by the Mexican Government for COVID-19 pandemic precautionary measures and reinitiated mining operation during the first week of June 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.

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.
