Fitzroy Minerals Reports Copper Recoveries of up to 82.6% from Mini-Column Testing, with Preliminary Larger-Scale Results Trending Higher, at the Buen Retiro Copper Project, Chile

Fitzroy Minerals announced positive initial metallurgical test results from its Buen Retiro Copper Project in Chile, with mini-column heap leach recoveries reaching up to 82.6% for mixed material after 21 days, alongside low-to-moderate acid consumption. Preliminary 1-metre column tests are trending higher, projecting recoveries up to 95% for mixed material after 70 days. The company also noted favorable rock hardness and abrasiveness, which should positively impact crushing costs, and plans to incorporate these results into a PFS for Q2 2027.

ATEX Record Phase VI Program Expands the High-Grade B2B Breccia Strike by 50% and Discovers New Mineralization Beyond B2B to the East and North

ATEX Resources announced exceptional results from its Phase VI drill program at the Valeriano Copper-Gold Project in Chile, significantly expanding the high-grade B2B breccia strike by 50% to 600m and discovering new mineralization to the east and north. The program, totaling 28,400m, delivered several of the highest-grade intercepts in the company's history, including 40m of 4.83% CuEq. These results, coupled with a substantial existing resource estimate, provide a strong foundation for an updated Mineral Resource Estimate in 2H 2027 and further exploration in Phase VII.

Thick, High-Grade, Surface Enrichment Zone Extends at La Verde

Hot Chili Limited announced new drill results from its La Verde copper-gold porphyry discovery in Chile, highlighted by wide, high-grade, near-surface intercepts. Hole DKP063 returned 398m grading 0.45% CuEq from surface, including 62m at 0.91% CuEq from 20m. The results extend the known mineralization and support the potential for a high-grade starter pit, with the company targeting a maiden Mineral Resource Estimate and an updated Pre-Feasibility Study for the Costa Fuego project.
