Altaley has a US $12 million loan facility in place with Accendo Banco and has drawn partial funding under the loan facility. This loan funding was part of a larger funding package totaling US $25 million as previously announced, February 23, 2021. Funds raised through this larger funding package have been, and are being, used to repay debt to Nyrstar Canada (Holdings) Ltd, fund construction of the Company's Tahuehueto Gold mine Project and provide working capital to the Company.

To date, construction progress at Tahuehueto has advanced to an estimated 80% of completion. Remaining capital expenditures required to complete construction are estimated to be approximately US $6.7 million plus start-up operating capital. To view additional images of the progress at Tahuehueto visit our website <here>.

Altaley currently, on a consolidated basis, has approximately US$9.5 million of cash held in banking institutions, of which US$6.5 million is unrestricted cash immediately available for operations.

Altaley's Campo Morado mine is cash flow positive with a 2021 six month mine operating profit of C$14.2 million and total income of C$11.4 million up to June 30, 2021.

Construction of Tahuehueto has been proceeding on time and on budget and management expects that any shortfalls in operating or construction capital for Tahuehueto caused by the Accendo Banco situation, can be realized through alternative funding mechanisms (discussions with funding sources underway) or, from ongoing Campo Morado operating profit.

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 were 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 using words and phrases such as "plans," "expects," "scheduled," "estimates," "forecasts," "intends," "anticipates" or variations of such words and phrases.

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.
