Mr. Alastair McIntyre reports ALTIPLANO INTERSECTS NEW 400 M MINING LEVEL AND UPDATES CU-AU-FE CONCENTRATE SALES Altiplano Metals Inc. has provided operational updates at the Santa Beatriz copper-gold-iron mine and processing updates at El Penon processing plant, located approximately 30 kilometres south of La Serena, Chile. Highlights: During the month of September, the company extracted 2,270 tonnes of copper-gold-iron mineralized from the 425-metre level along northeast and southwest mining drifts. Shipments to El Penon processing plant to support the production of copper/gold and iron concentrates were 1,910 tonnes. At the end of September, 360 tonnes remain on site with shipment to the plant expected in October. The development in the 400-metre tunnel, accessed through the 414-metre opening, reached the 400-metre level in early October. A total of 54.32 metres have been developed to date: Access along this level and development of the lower levels will be further reviewed to ensure grade control is maximized. Massive sulphides were observed in the vein (chalcopyrite and pyrite), as well as magnetite and secondary minerals such as apatite and actinolite. During the reporting period from July to September, 2025, the company generated $256,717 (U.S.) ($360,600 (Canadian)*) from the sale of 128.7 tonnes of copper/gold concentrate representing $222,600 (U.S.) and 483 tonnes of iron representing $34,117 (U.S.). * Canadian dollar equivalent is from reference and as determined by the Oct. 14 Bank of Canada noon rate of 1.4046. President and chief executive officer Alastair McIntyre commented: "Reaching the lower level of the mine provides us the opportunity to access material with higher grades and begin mining on multiple faces. This improves our output at the mine and increase the efficiencies at the plant as higher volumes with better grade improves concentrate production. We are also pleased to see revenues improve from the previous quarter results." Board of directors The company further announces James Farley has retired from his role as director. The board of directors expresses its sincere appreciation for Mr. Farley's contributions to the audit and technical committees and his leadership during his tenure.
