Vancouver, May 8, 2024 - Sierra Madre Gold and Silver Ltd. (TSXV: SM) (OTCQX: SMDRF) ("Sierra Madre" or the "Company") is pleased to announce that First Majestic Silver Corp. ("First Majestic") has today advanced the Company a non-revolving, secured term loan ("Loan") in the amount of US$5 million pursuant to the terms of a loan agreement entered into by the Company and First Majestic.

Since acquiring the La Guitarra Silver-Gold Mine Complex in Estado de Mexico, Mexico in March 2023, the Company has made notable advancements to the facilities, equipment, and infrastructure at the mine site. The Company intends to use the proceeds of the Loan to complete this work, which will include: lead orders for critical mining equipment, processing facility upgrades, mill repairs, full staffing arrangements, and final underground development readied for operational restart.

Alex Langer, Sierra Madre's President and CEO, states: "After a thorough and extensive process, we are very pleased to announce this non-equity, non-dilutive financing. The Loan will allow us to complete all necessary steps for the possible restart of the fully permitted La Guitarra Silver and Gold mine. We would very much like to thank First Majestic for providing this funding, and for their continued support of La Guitarra."

Loan Details

The Loan is for a two (2) year term, and bears interest at a rate of 15% per annum, compounded monthly, which will be due and payable to the lender starting six (6) months from the commencement date of the Loan, and due on the last day of each calendar month thereafter. The Company may pay back the Loan plus accrued and unpaid interest to the lender at any time, without penalty.

As security for the Loan and the Company's performance of its obligations under the loan agreement, the Company has agreed to pledge all of the shares of its wholly-owned subsidiary that owns La Guitarra in favour of First Majestic, and the Company and certain of its subsidiaries have entered into general security agreements in favour of First Majestic.
