Montero Mining completes 625-meter drillhole at Elvira gold project in Chile

• Montero Mining completed drillhole MON-ELV-02 to 625 meters at the Elvira Gold Project in northern Chile, its first finished hole of 2026.
• Core logging indicates a high-sulphidation alteration system with widespread pyrite, aligning with a modeled IP chargeability anomaly.
• Altered volcanic rocks extend to 195 meters; a porphyry intrusion runs from 195 meters to end-of-hole, with oxidation base near 253 meters.
• Assays are pending to determine whether the sulphide-bearing intervals carry gold, silver, or copper; initial samples sent to AAA Laboratory.
• Drilling has started on follow-up hole MON-ELV-03 as results are fed into an updated 3D geological model.
