Telson Mining Corporation Campo Morado Update

Vancouver, British Columbia, Sept 5, 2018

Telson Mining Corporation (“Telson” or the “Company”) (TSX- V – TSN, OTC Pink – SOHFF, Frankfurt – TSGN

(formerly SQ82)) provides summary of Q2 2018 financial report.

On Wednesday, August 29, 2018, the Company filed its condensed interim consolidated financial statements

for the three and six months ended June 30, 2018 and 2017 (“Q2 Quarterly Report”). The Q2 Quarterly Report

presented financial information for April, May and June 2018, that included 45 days of pre-production and 45

days of commercial production at the Campo Morado mine. Telson declared commercial production at

Campo Morado effective May 15, 2018 (see news release dated May 23, 2018).

Telson advises that concentrate cash sale value realized from pre-production under International Financial

Reporting Standards (“IFRS”) are not accounted as revenue on the condensed interi m consolidated financial

statement of loss , instead these are capitalized net of production costs and de velopment expenses and

presented as mineral interest and development assets upon reaching commercial production. Accordingly,

Telson capitalized a net profit of approximately C$7.3 million for Campo Morado as mineral interest and

development assets during the pre-production period from Jan 1 to May 15, 2018.

During the last 45 days of the quarter or since the start of commercial production on May 15, 2018 to June 30,

2018, the Company recorded a total amount of C$987,055 as mine operating earnings which is presented on

the Q2 Quarterly Re port. Mining operations at Campo Morado are currently processing at a rate of

approximately 2,000 tonnes per day which management intends to increase to 2,500 in the near future and

increase towards 3,000 by the end of this year.

Antonio Berlanga, CEO states, “ Our outstanding Campo Morado operations team have performed beyon d

expectations and continue to work diligently to improve the operational re sults at Campo Morado. Pre -

production and more recen tly, commercial production , has funded the acquisition of surface and

underground equipment as well as processing plant equipment, all of which are allowing a steady increase in

production rates and corresponding concentrate sales. Telson will continue to invest in Campo Morado to

increase production capacity, mill recoveries and quality of concentrates to maximize the mine’s profitability.”

Telson’s Campo Morado Mine has achieved direct site costs for mining, milling and administration during Q2

of approximately US$56.6, US$51.6 and US$51.8 per tonne respectively for, April, May and June. These current

direct site costs are approximately 36% lower than the estimated direct site costs of US$72.26 per tonne used

for the same categories in Telson’s recently published independent Preliminary Economic Assessment and

approximately 40% lower than the previous operator’s last year of production during 2014.

This press release was prepared under the supervision and review of Ralph Shearing, P.Geol., President and

Director of Telson Mining Corporation, a Professional Geologist registered in Alberta as a member of the

professional association APEGA, and a Qualified Person as defined by NI 43 -101. Data verification by Mr.

Cautionary Note Regarding Production Decisions and Forward-Looking Statements

It should be noted that Telson has 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). This will

soon be replaced by a pre-feasibility study (“PFS”) that will allow the application of modifying factors to the mineral

resources to allow a portion of them to be converted to mineral reserves.
