Altitude Minerals Ltd (ASX: ATT) provides a final exploration and drilling update for 2025, following an active and highly productive year across the Company’s Heavy Mineral Sands, Copper-Gold, and Silver-Gold portfolios in Australia and the United States.
The Managing Director has just returned from a field trip to Nevada, where the Company completed further drill-target refinement at the Firenze Silver & Gold Project, progressed logistics and contractor discussions, and reviewed multiple advanced gold, silver and copper opportunities with potential to complement the existing project pipeline.
2025 has been a transformational year for Altitude Minerals, with a strong pipeline of drill-ready targets established and three drilling programs completed in the last months of the year. The Company enters 2026 with momentum, defined drill programs, and multiple near-term catalysts, including recent positive HM results, pending assay results and upcoming drilling.
