NGEx Minerals (NGEX) Corporate Presentation summary

Strategic positioning and value creation

• Holds two world-class copper-gold assets, Lunahuasi and Los Helados, in the Vicuña District, a highly prospective and rapidly advancing mining region.

• Completed a successful Phase 3 drill campaign at Lunahuasi, tripling the mineralized volume and confirming three high-grade zones: Mars, Saturn, and Jupiter.

• Los Helados provides significant resource underpinning and optionality, with 2.08 Bt at 0.51% CuEq indicated and 1.08 Bt at 0.42% CuEq inferred resources.

• Plans to spin out royalties on Lunahuasi (1% NSR) and Los Helados (2% NSR) into a new RoyaltyCo, providing shareholders with long-term exposure and upside.

• Market capitalization of C$4.3B as of July 2025, with strong insider and Lundin Family ownership.

Lunahuasi project highlights

• Emerged as a major new high-grade copper-gold discovery, with bonanza-grade vein structures and long mineralized intervals, including 60m at 7.52% CuEq and 27.4m at 25.19% CuEq.

• Phase 3 drilling expanded the mineralized footprint to 1.5km x 1.1km x 1km, with the deposit remaining open in all directions.

• Discovered ultra high-grade free gold veins, including intercepts up to 504 g/t Au over 1.55m.

• Gold intercepts are comparable to world-class deposits, with intervals such as 104.8m at 14.74 g/t Au and 61.9m at 23.81 g/t Au.

• Part of a major new district, sharing a structural corridor with Filo del Sol and Los Helados.

Los Helados project highlights

• One of the largest undeveloped copper-gold porphyry deposits globally, located 9km north of Lunahuasi in Chile.

• Indicated resources: 2.08 Bt at 0.51% CuEq (18.4 Blbs Cu, 10.2 Moz Au, 97.5 Moz Ag); inferred: 1.08 Bt at 0.42% CuEq.

• Ownership: ~69% by NGEx, ~31% by JX Nippon; significant historical drilling and engineering work completed.

• Only major Latin American copper project not owned by a major mining company with existing operating infrastructure nearby.
