Aldebaran Resources Reports 1,728.9 m of 0.45% CuEq (0.41% Cu, 0.03 g/t Au & 1.34 g/t Ag), including 756 m of 0.68% CuEq (0.61% Cu, 0.03 g/t Au & 2.12 g/t Ag) at the Altar Copper-Gold Project in San Juan, Argentina

Aldebaran Resources reported significant drill results from its Altar Copper-Gold Project in San Juan, Argentina, including a notable 1,728.9-meter intercept grading 0.45% CuEq in hole ALD-26-260. The 2025-2026 infill and geotechnical drilling program aims to upgrade Inferred resources to higher-confidence categories and will incorporate over 40,000 meters of drilling at Altar and 30,000 meters at the new Radio Porphyry target into an upcoming 2026 mineral resource estimate. These results are expected to support a Pre-Feasibility Study scheduled for 2027.

Sendero Resources Rebuilds Peñas Negras Drill Assay Database, Applying Consistent CuEq Methodology Across 77 Historical Holes

Sendero Resources has re-evaluated 77 historical drill holes from its Peñas Negras copper-gold project in Argentina, applying a consistent copper equivalent (CuEq) methodology. This work provides a unified, project-wide view of mineralization, which begins near surface and extends to over 350 meters downhole. Notable intercepts include 44.2 meters at 1.23% CuEq in PNDH-06 and 43.6 meters at 1% CuEq in PND-02.

Sendero Resources Rebuilds Peñas Negras Drill Assay Database, Applying Consistent CuEq Methodology Across 77 Historical Holes

Sendero Resources Corp. has completed a re-evaluation of historical drill data from its Peñas Negras copper-gold project in La Rioja, Argentina, applying a consistent CuEq methodology across 77 holes. This analysis highlights significant copper-equivalent intercepts, including 44 metres grading 1.23% CuEq within 236 metres of 0.57% CuEq in hole PNDH-06, reinforcing the project's potential. The company plans a fully funded drill program based on these results, which show mineralization extending from near surface to over 350 metres depth.
