NGEx Minerals (NGEX) Corporate presentation summary

Regional and geological context

• Lunahuasi is located in the Vicuña District, a prolific mining belt with several major deposits and operating mines in Chile and Argentina.

• The region features complex geology with Permo-Triassic basement blocks, high-angle reverse faults, and multiple magmatic and mineralization events.

• Lunahuasi is characterized by a Cu-Au-Ag vein system and is situated near other significant deposits like Los Helados and Filo del Sol.

Discovery and exploration history

• Initial drilling at Lunahuasi began in January 2023, with significant high-grade intersections reported in April and July 2023.

• By April 2024, two distinct mineralization styles were confirmed: bonanza-grade veins and stockwork mineralization.

• In May 2025, a major copper-gold porphyry system was discovered, including a 1,619.4m interval at 0.87% CuEq.

Mineralization and drilling highlights

• Multiple mineralization styles are present: high-sulphidation Cu-Au-Ag veins, porphyry copper-gold, and ultra high-grade gold in quartz veins.

• Notable drill results include 60m at 7.52% CuEq, 51.1m at 13.84% CuEq, and 27.4m at 25.19% CuEq.

• Bonanza gold grades have been intersected, with intervals such as 1.4m at 19.45 g/t Au and 1.8m at 16.70 g/t Au.
