• Visible chalcopyrite, magnetite, pyrite and molybdenite observed in maiden diamond drill hole at Three Saints IOCG project in Chile
• Nominal cash payment of USD $30,000 to secure sole access rights to Los Loros Cu-Mo Porphyry project in Chile
• High-grade rare earth results up to 3.73% TREO confirmed at Virgin Mountain project in Arizona, USA

Lodestar Minerals has reported on its activities and progress across its international portfolio during the March 2026 quarter. At the Three Saints IOCG project in Chile, the company's maiden diamond drill hole intersected extensive copper sulphide mineralization, including chalcopyrite, molybdenite and magnetite, over a 400m extent. The mineralization showed increasing intensity with depth, supporting the presence of a large-scale hydrothermal system. A second step-out drill hole is currently underway to further test the extent and continuity of the mineralized system. At the Los Loros Cu-Mo Porphyry project, also in Chile, Lodestar secured a nominal cash payment of USD $30,000 to gain sole access rights to the project. Historical drilling has confirmed a significant Cu-Mo porphyry system, with high-grade gold mineralization also identified. Lodestar plans to utilize modern exploration techniques to unlock the project's potential. In the USA, at the Virgin Mountain Heavy Rare Earth project in Arizona, Lodestar confirmed high-grade rare earth mineralization up to 3.73% TREO, with a high proportion of valuable heavy rare earth elements. Mineralogical analysis identified xenotime as the dominant rare earth-bearing mineral, which is significant given its association with heavy rare earths and proven commercial processing pathways. An upcoming field program is planned to further assess the 5km structural trend hosting the mineralization.
