NGEx Minerals (NGEX) Lunahuasi Geology Presentation summary

Exploration highlights

• Phase 3 drilling at Lunahuasi has delivered some of the world's highest copper-gold grades, with multiple holes intersecting significant mineralization, including bonanza gold and silver values over substantial widths.

• High-grade intersections are present in all directions, with no zonation observed, indicating a rare combination of large size and high grades.

• Notable results include 86.6m at 4.39% CuEq, 205.35m at 5.08% CuEq, and intervals with over 30% CuEq, as well as gold values up to 47.2 g/t and silver up to 1,450 g/t.

• The deposit remains open in all directions, with most holes ending in mineralization, suggesting significant upside potential.

• The geological model suggests current drilling may only cover a small part of the overall system.

Project and regional context

• Lunahuasi is part of the Vicuña district, located near major mines and deposits such as Los Helados, Filo del Sol, and Josemaria, with established infrastructure in the region.

• The Los Helados deposit, nearby, contains 510 Mt at 0.72% CuEq (Indicated) and 8.3 Blbs Cu (Inferred), highlighting the district's large-scale potential.

• The regional geology features multiple mineralization styles, including high, intermediate, and low sulphidation systems.

• The current mineralized volume at Lunahuasi is at least 900m x 400m x 960m, with high sulphidation vein systems and porphyry targets identified.

Technical approach and innovation

• The Phase 3 drill program was expanded from 20,000m to 25,000m, testing long, mid, and short-range targets, with directional drilling and real-time data acquisition.

• Advanced geological core scanning, mineral mapping, and XRF analysis are integrated into the workflow, enhancing data quality and interpretation.

• A state-of-the-art data management system enables near real-time monitoring and integration of drill and geological data.

• Copper equivalent calculations are based on $3.00/lb Cu, $1,500/oz Au, $18/oz Ag, and 80% metallurgical recoveries.
