Minera Alamos Provides Santana Operations Update

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.
