Core Insights - Core Silver Corp. has confirmed the presence of a large copper-molybdenum porphyry system at the Laverdiere Copper Project through its 2025 drilling campaign, with significant assay results indicating high-grade mineralization [1][2][18] Drilling Results - The 2025 drilling campaign at the Laverdiere Copper Project included seven diamond drill holes totaling 3,857.17 meters, revealing extensive copper and molybdenum mineralization [17][18] - Notable intersections include hole LAV25-011, which returned 24.80 meters of 0.17% Cu, 1.2 g/t Ag, and 0.03% Mo, with higher-grade intervals showing up to 7.31% Cu and 1.01% Mo [6][28] - Hole LAV25-010 intersected 10.50 meters of 0.11% Cu and 2.3 g/t Ag, with localized high-grade veins including 0.50 meters of 1.97% Cu and 45.9 g/t Ag [4][5] Geological Context - The Laverdiere System exhibits characteristics similar to some of the largest porphyry deposits globally, indicating high prospectivity for copper-gold mineralization [14] - The system is geochemically situated within the 'Chuqui Fertility Window', suggesting a favorable environment for mineralization [14][21] Mineralization Characteristics - The mineralization at Laverdiere is extensive, with delineated porphyry mineralization extending over 5.2 kilometers laterally and to depths exceeding 800 meters [16][18] - The presence of well-developed copper-molybdenum-gold-silver-bearing porphyry veins indicates potential for significant stacked grades in areas of higher vein density [15] Exploration Potential - Three zones of anomalous copper and molybdenum values have been identified through soil sampling, suggesting potential clustered porphyry centers within a 4-kilometer-long mineralized corridor [13] - The ongoing exploration at Laverdiere is expected to further define the scale and fertility of the porphyry system, with remaining areas largely untested [16][18]
