Montero Mining logs 625-meter Elvira drillhole, flags pyrite-bearing high-sulphidation alteration
  • Montero completed geological logging on replacement drillhole MON-ELV-02 at the Elvira Gold Project in northern Chile.
  • The hole reached 625 meters, intersecting advanced argillic-altered volcanic rocks to 194 meters, then feldspar-quartz-amphibole porphyry to end-of-hole.
  • Logging identified widespread quartz-alunite-pyrite alteration, with oxidation ending near 253 meters; pyrite-bearing sulphides observed below that level.
  • Montero linked the pyrite zones to a modeled IP chargeability anomaly, supporting its integrated targeting model for the 2026 drill program.
  • Assay results are pending; historical adjacent hole EL-12 reported 4 meters at 4.9 g/t gold from 264-268 meters.
