(TSXV: SM) (OTCQX: SMDRF) ("

Sierra Madre

" or the "

Company

") is pleased to announce that full

commercial production at the 100% owned Guitarra Mine Complex located in Estado de Mexico,

Mexico, commenced on January 1, 2025. The processing plant, underground mine, and all aspects of

the operation have now been running at the current capacity of 500 wet metric tonnes per day for the

past 90 days. Monthly gold and silver concentrate shipments, concentrate inventories, freshly mined

material stockpiles and revenues generated from sales; have all increased on a material basis.

Chief Executive Officer, Alex Langer commented, "We are delighted to announce full commercial

production at Guitarra. This will allow us to share proper mining statistics; including revenues, costs,

profits, and an all in sustaining cost (AISC) per ounce of silver. We very much look forward to sharing this

information during our quarterly and annual financials moving forward."

Gregory K. Liller, Chief Operating Officer wishes to thank the operating team. "I am very proud of the

staff and workers at La Guitarra.

The maintenance and plant personnel repaired and rebuilt the existing

equipment on budget and ahead of schedule making an early restart possible.

Even more important,

they have kept everything running.

The mining and technical services departments worked hard to make

the test mining phase a success. Above all, everyone has worked together to develop safe and efficient

operating procedures and a cost-conscious outlook. I believe that establishing this working culture from

the beginning bodes well for future operations."

Operational numbers for 2024 during test mining:

A total of 1,292.5 dry metric tonnes of concentrate were shipped in 2024 with an additional 94.6

tonnes in inventory at December 31, 2024.

Cautionary Note Regarding Production Decisions

The Company's decision to place the mine into commercial production, expand a mine, make other

production related decisions, or otherwise carry out mining and processing operations, is largely based

on internal non-public Company data and reports from previous operations and the results of test mining

and processing.

The Company is not basing any production decisions on NI 43-101 compliant reserve

estimates, preliminary economic assessments or feasibility studies and, as a result, there is greater risk

and uncertainty as to future economic results from the Guitarra Mine Complex, including increased

uncertainty of achieving any particular level of recovery of minerals or the cost of such recovery, including

increased risks associated with developing a commercially mineable deposit, 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.
