Norsemont Commences Drill Program at Choquelimpie Project

Executive Summary

• Norsemont Mining announced the start of its Phase 3 exploration drilling at the 100% owned Choquelimpie gold‑silver‑copper project in northern Chile.
• The program will drill up to 5,000 m across ~20 holes using two Longyear LF230 diamond rigs, targeting deeper extensions of high‑grade hydrothermal breccia bodies below the current resource envelope.
• Drilling is scheduled to begin immediately and run through late December, with a 24‑hour operating schedule and expected “steady progress” and regular news flow over the coming months.

Key Details

• Program Scope: Up to 5,000 m of diamond drilling; ~20 holes averaging 250 m each.
• Equipment: Two Longyear LF230 track‑mounted drill rigs (one already on site, second arriving next week).
• Contractor: DV Drilling Ltd. (Coquimbo, Chile) engaged by Norsemont’s subsidiary SCM Vilacollo to execute the campaign.
• Target Zones: Deeper extensions of higher‑grade hydrothermal breccia bodies in zones such as Choque, Vizcacha and Suri, below the existing mineral resource envelope.
• Schedule: Drilling commences immediately; 24‑hour operation; expected completion by late December 2025.
• Historical Context: Prior production (1988‑1996) focused on near‑surface oxidized ore (20‑100 m depth). Phase 3 aims to test the deeper sulphide resource potential.
• Qualified Person: David Flint, MSc, AIPG‑CPG, Chief Geologist – NI 43‑101 qualified person reviewed and approved technical information.
