Minera Alamos Provides Santana Operations Update

Rhea-AI Summary

Minera Alamos Inc. (TSXV: MAI) has provided an operations update for its Santana gold mine in Sonora, Mexico. Mining and stacking operations began last month at the new Nicho Main zone deposit, with approximately 900 ounces of newly mined gold stacked on the leach pad through June. The company expects to stack 1,300-1,500 ounces of gold in the next month, approaching the lower end of initial monthly mining rates.

Gold grades averaged about 0.9 g/t through June. The company is optimizing blasting operations and crushing arrangements to improve leaching conditions. Minera Alamos is also considering mobilizing its agglomeration system for more operational flexibility. The shift to the Nicho Main Zone pit is expected to provide a significant improvement in gold stacking activities and help operations return to being cash generative as gold prices strengthen.

Nicho Main Zone Expanding Mining Operations

Toronto, Ontario--(Newsfile Corp. - July 18, 2024) - Minera Alamos Inc. (TSXV: MAI) (the "Company" or "Minera Alamos") is pleased to provide a brief operations update for its Santana gold mine in Sonora, Mexico.

Key Developments

Mining and stacking operations commenced last month with approximately 900 ounces of newly mined gold stacked on the leach pad (through the end of June) during the initiation of mining operations at the new Nicho Main zone deposit. Access to the Nicho Main gold mineralization in the pit is steadily improving with the opening up and extraction of the first few benches. The Company plans to ultimately have access to two simultaneous working areas that, in addition to providing better traffic flow for the mobile equipment, will allow for more efficient planning for grade control and waste stripping management. Presently, estimates for the next month of mining and stacking operations are 1,300-1,500 ounces of gold placed on the heap leach pad which is approaching the lower end of the initial monthly mining rates included in the Nicho Main zone start-up plans. With mine access improving, plans are to activate two additional trucks in July which expands the mobile fleet size to the anticipated normal levels for the current mine plan.

Gold grades averaged approximately 0.9 g/t through the end of June and following July production data there should be an update on grade reconciliation for the first months of full operations at Nicho.

The more brittle nature andesite host rocks that comprise the bulk of the gold mineralization at the Nicho Main Zone combined with extensive weathering of the near surface material has resulted in the production of finer mined material than was experienced during the previous activities at the Nicho Norte area. Consequently, additional optimization work is underway in the new open pit to reduce the quantity of explosives used in the mine blasting operations. Combined with changes in the site crushing arrangements, these initiatives should result in more optimal operating (leaching) conditions that will continue to be monitored and adjusted as mining activities progress deeper into the resource. The Company is also looking at other possible improvements including the mobilization of the agglomeration system it had previously acquired in 2020 so that more operating flexibility is available as new areas of mineralization are brought into the overall Nicho mine plan. The remaining parts of the crushing system acquired in that transaction are destined for the Cerro de Oro operation when that project is built.

"The commencement of mining operations at the new Nicho Main Zone pit has begun reasonably within expectations, especially given there are always aspects of opening a new mining zone to be learned from and optimized. Importantly, the new mining plan provides a significant improvement in gold stacking activities at the Phase 1 leach pad. This positive shift in mine operations, as gold prices strengthen considerably, should provide a strong foundation for operations to return to being cash generative as the year continues," stated Doug Ramshaw, President of Minera Alamos. "The operating team in Mexico is delivering on our previously announced plans and as the main pit continues to open up the benefits of Santana returning to a steady state of operation should be comforting to shareholder and all our stakeholders on a go forward basis. I'd like to take this opportunity to thank our team on the ground and Trigusa, our mining contractor, in these early months of renewed operations at Santana."

Cautionary Statement

The Company made its production decision at the Santana gold mine without having completed a feasibility study demonstrating economic and technical viability. As such, there may be increased uncertainty of achieving planned production levels, estimated recovery of gold, the costs associated with such recovery, including increased risks associated with developing a commercially mineable deposit. Historically, such projects have a much higher risk of economic and technical failure.
