Sierra Madre Provides Positive Update to Test Mining and Processing
Sierra Madre Provides Positive Update to Test
Mining and Processing
Vancouver, British Columbia--(Newsfile Corp. - September 5, 2024) - Sierra Madre Gold and Silver Ltd.
(TSXV: SM) (OTCQX: SMDRF) ("
Sierra Madre
" or the "
Company
") is pleased to give an update on
the progress of test mining and processing at the Guitarra mine complex.
The testing of the flotation plant began on the 25
th
of June, 2024 and has been in continuous daily
operation. A total of 20,401 tonnes of material containing economically interesting silver and gold
mineralization has been processed as of August 31
st
for an average production rate of 300 tonnes per
day since inception of test mining. Five (5) shipments totalling 335 dry metric tonnes of silver gold
concentrate have been delivered to MRI Trading AG under the Company's 24-month contract.
Provisional payment gold and silver concentrate grades ranged from 2,752 g/t to 3,442 g/t silver and
28.6 to 36 g/t gold. Final assay grades will be determined upon shipment to the smelters.
Test mining began with development mineralization from the Guitarra mine, transitioning to economically
attractive in situ mined material from both long hole and shrinkage stopes in August. Production of back
fill material ("retaques") from stopes mined in the 1990's and early 2000's was increased as planned.
These retaques were derived from material below the 8 to 10 gram per-tonne gold equivalent cutoff used
at the time, which had to be blasted in order to mine the above cut-off ore. Once emptied, these stopes
are scheduled to receive tailings paste fill, for which the mine is fully permitted.
Chief Operating Officer, Greg Liller commented, "I am very pleased with the operating results to date.
The Guitarra team is doing an excellent job of moving operations towards a sustained production rate of
350 tonnes per day, our next test production goal.
Upon achieving 350 tonnes per day the team has an
orderly plan in place to move towards 410 tonnes per day, then to the commercial mining and
processing rate of 500 tonnes per day before year end".

Cautionary Note Regarding Production Decisions
The Company's decision to potentially 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. 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 decision.
