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

Sendero Resources has rebuilt and re-evaluated the historical drill assay database for its Peñas Negras copper-gold project in Argentina, applying a consistent copper equivalent (CuEq) methodology across 77 historical holes. This re-analysis highlights several significant intercepts, including 24 meters grading 1.53% CuEq within a broader 236-meter interval of 0.57% CuEq in hole PNDH-06. The company notes that mineralization begins near surface and extends to over 350 meters downhole, providing a project-wide view of the historical drilling and reinforcing the project's potential for future exploration.
