Norsemont Mining Commences Phase 3 Drilling at Choquelimpie Project

November 14, 2025 — Leads & Copy — Norsemont Mining Inc. has started its Phase 3 exploration drill program at the 100%-owned Choquelimpie high-sulfidation gold-silver-copper project in northern Chile, according to a news release. The program includes up to 5,000 meters of diamond drilling utilizing two diamond drill rigs. Drilling is scheduled to begin immediately and continue through late December.

According to Norsemont CEO Marc Levy, recent work has highlighted significant potential for higher-grade gold zones at depth beneath the current resource and along strike. He added the program marks an important step forward as the company continues to define the scale and continuity of mineralization across the project and expects steady progress and consistent news flow over the coming months with two rigs on site.

The Phase 3 drill campaign at Choquelimpie is designed to evaluate down-dip extensions of high-grade gold mineralization hosted within hydrothermal breccia zones. The program will comprise up to 20 holes averaging 250 meters in length. Norsemont, through its wholly owned Chilean subsidiary SCM Vilacollo, has engaged DV Drilling Ltd. of Coquimbo, Chile, to conduct the program. DV Drilling will mobilize two Longyear LF230 track-mounted diamond drill rigs, which will operate on a 24-hour schedule throughout the campaign.

Historical production at Choquelimpie during the period of 1988 to 1996 focused primarily on oxidized near-surface mineralization between 20 and 100 m depth, depending in the type of rock, alteration and mineralogy. Consequently, much of the exploration at the Project focused on this near surface oxide resource without testing the deeper, potentially larger, sulphide resource. The Phase 3 drill program aims to systematically assess this deeper resource potential by targeting the geometry of the higher-grade breccia bodies.

David Flint, MSc, AIPG-CPG, and Chief Geologist of Norsemont Mining Inc.; a qualified person as defined in NI 43-101, has reviewed and approved the technical information in this press release.
