Collective Mining has expanded the footprint of the porphyry system at San Antonio by cutting 172.40 metres at 1.40 g/t Au, 0.16% Cu, 17 g/t Ag, and 68 ppm Mo in hole SAC-18. The hole was terminated prematurely while in strong mineralization, and multiple mineralized zones have been identified. The San Antonio project covers a three-kilometre area with three porphyry-related mineralized phases, including a large phyllic altered halo zone, a gold and silver-rich sheeted veinlet system, and a gold-copper-silver-molybdenum porphyry system.
