Sierra Madre Provides Positive Update to Test Mining and Processing
Sierra Madre Gold and Silver (TSXV: SM) (OTCQX: SMDRF) has provided a positive update on test mining and processing at the Guitarra mine complex. Since June 25, 2024, the flotation plant has been in continuous daily operation, processing 20,401 tonnes of silver and gold mineralized material at an average rate of 300 tonnes per day. The company has delivered five shipments totaling 335 dry metric tonnes of silver-gold concentrate to MRI Trading AG under a 24-month contract.
Provisional payment grades for the concentrate ranged from 2,752 g/t to 3,442 g/t silver and 28.6 to 36 g/t gold. The company has transitioned from development mineralization to in situ mined material from long hole and shrinkage stopes, as well as increased production of backfill material from previously mined stopes. Sierra Madre aims to reach a sustained production rate of 350 tonnes per day, with plans to increase to 410 tonnes per day and ultimately achieve a commercial rate of 500 tonnes per day before year-end.
Sierra Madre Gold and Silver (TSXV: SM) (OTCQX: SMDRF) ha fornito un aggiornamento positivo sulle attività di sfruttamento e lavorazione presso il complesso minerario di Guitarra. Dal 25 giugno 2024, l'impianto di flottazione è in funzione continua, trattando 20.401 tonnellate di materiale mineralizzato contenente argento e oro a una media di 300 tonnellate al giorno. L'azienda ha effettuato cinque spedizioni per un totale di 335 tonnellate metriche secche di concentrato di argento-oro verso MRI Trading AG nell'ambito di un contratto di 24 mesi.
I gradi di pagamento provvisori per il concentrato variavano da 2.752 g/t a 3.442 g/t di argento e 28,6 a 36 g/t di oro. L'azienda è passata dalla mineralizzazione di sviluppo al materiale estratto in situ proveniente da estrazioni a lungo foro e stope di restringimento, oltre a un aumento della produzione di materiale di riempimento da stope precedentemente minerate. Sierra Madre punta a raggiungere un tasso di produzione sostenibile di 350 tonnellate al giorno, con piani per aumentarlo a 410 tonnellate al giorno e infine raggiungere un tasso commerciale di 500 tonnellate al giorno entro la fine dell'anno.

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 25th 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 31st 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.
