(TSX-V:ANDC) (FSE:FIR)\n(OTCQB:PMMCF) is pleased to report a wide intercept of\ncopper-gold-silver mineralization at Piuquenes East that significantly\nexpands the vertical extent of the mineralized envelope and confirms\nincreasing gold grades and intensity of porphyry stockwork veining\nlaterally and to depth.\n\n\nDrill hole PIU09, only the third drilled at Piuquenes\nEast, intersected a broad, continuous interval of copper–gold\nmineralization hosted within strongly veined, dioritic porphyry with\nintense sericitic alteration overprinting potassic, confirming the\npresence of a new vertically extensive gold-rich\nporphyry Cu–Au–Ag system within the Piuquenes-Altar cluster\n\n\nHIGHLIGHTS\n\n\n\n\nHole PIU09 intersects: \n\n\n\n\n126 m at 0.46% Cu,\n0.53 g/t Au, 2.14 g/t Ag from\n529 m; \n\n\n\nwithin 402 m at 0.25% Cu, 0.21 g/t Au, 1.19 g/t Ag from 253\nm. \n\n\n\n\n\nWell developed A-type veins coincident with chalcopyrite ±\nbornite mineralization. \n\n\n\nHigher gold grades and increasing intensity of A and\nB-type veining observed at depth, consistent with proximity to the\nporphyry core. \n\n\n\nBornite-rich potassic alteration with higher gold\ngrades may be preserved beneath the sericitic overprint. \n\n\n\nFollow-up drilling underway to evaluate the northern\ncontinuity of the Cu–Au mineralized porphyry system at Piuquenes\nEast. \n\n\n\nA second rig has commenced drill testing of a strong,\ndiscrete geophysical anomaly (MT) at Piuquenes North, immediately\nadjacent to the Piuquenes Central deposit (refer 10 February\n2026 News Release). \n\n\n\n\n\nClick Image To View Full Size\n\n \n\nFigure\n1: Piuquenes Cu-Au project\nlocation map, San Juan Province, Argentina.\n\n \n\nGeology and Mineralization -\nPIU09\n\n\nFollow-up drilling at Piuquenes East continues to\nexpand porphyry copper-gold mineralization first intersected in hole\nPIU06 (208 m at 0.31% Cu,\n0.13 g/t Au, 1.24 g/t Ag from 292 m including  \n     98 m at 0.49% Cu, 0.16\ng/t Au, 1.26 g/t Ag from 292 m (refer 30 April 2025\nNews Re...
