NGEx Minerals plans phase 4 exploration at Lunahuasi

Executive Summary

• NGEx Minerals Ltd. announced a Phase 4 exploration program at the Lunahuasi copper‑gold‑silver project, targeting up to 25,000 m of diamond drilling beginning early October 2025.
• The program will test all four identified mineralization styles, expand the three named high‑grade zones (Mars, Saturn, Jupiter), and pursue long‑range targets to delineate the broader porphyry system.
• An investor day is scheduled for September 25 2025 to present the upcoming drill campaign and project updates.

Key Details

• Drill Program Scope: 8 rigs, up to 25,000 m of drilling (total cumulative drilling since discovery: ~43,250 m).
• Objectives by Range:
• Short‑range: Resource definition and expansion of Mars, Saturn, Jupiter zones.
• Mid‑range: Step‑out drilling to discover new high‑grade zones from existing intersections.
• Long‑range: Test district‑scale anomalies and extend the porphyry copper‑gold system.
• Mineralization Styles Targeted:
  1. High‑sulphidation Cu‑Au‑Ag veins
  2. Intermediate sulphidation epithermal Au veins
  3. Disseminated/stockwork high‑sulphidation Cu‑Au mineralization
  4. Porphyry Cu‑Au system
• Phase 3 Highlights (for context):
• DPDH043 – 46.80 m @ 9.55 % CuEq (6.63 % Cu, 3.05 g/t Au, 79.2 g/t Ag).
• DPDH029 – 823.10 m @ 1.17 % CuEq.
• DPDH027 – 743 m @ 0.55 % CuEq (0.43 % Cu, 0.13 g/t Au, 2.3 g/t Ag).
• Drilling Schedule: Start early October 2025; continue through May 2026 (austral winter onset).
• Rig Capabilities: Includes rigs capable of >2,000 m depth and horizontal drilling to maximize efficiency and reduce rig moves.
• Investor Day: Thursday, Sept 25 2025, Ivey Donald K. Johnson Centre, Toronto – live webcast available; recording posted thereafter.
• Qualified Person: Bob Carmichael, BASc, PEng (VP Exploration) reviewed technical disclosure per NI 43‑101.
