Copper Giant Resources Announces Metallurgical Test Results from Mocoa Copper-Molybdenum Project

October 9, 2025 — Leads & Copy — Copper Giant Resources (TSXV: CGNT) (OTCQB: LBCMF) (FRA: 29H0) announced positive results from bench-scale metallurgical testing on core samples from its Mocoa copper-molybdenum project in Putumayo, Colombia. The tests showed copper recovery rates up to 92% and molybdenum recovery rates up to 97%, exceeding the current resource model assumptions.

Ian Harris, Copper Giant President & CEO, stated the Mocoa project continues to improve and the initial lab tests exceeded recovery assumptions. The company is aggressively drilling to expand the pit constrained resource of 4.6 billion pounds of copper and 511 million pounds of molybdenum. With over 500 million pounds of molybdenum, Mocoa is emerging as a large undeveloped molybdenum deposit.

Metallurgy highlights include strong recoveries in initial bench-scale rougher flotation laboratory tests. The molybdenum mineralogical analysis shows 97% of molybdenite reported as free grains. Copper mineralization is dominated by chalcopyrite, indicating a conventional flotation pathway. Deleterious elements were barely detected, supporting the potential for clean, high-recovery concentrates.

The next set of testing will optimize reagents for both molybdenum and copper and create a simulated flow sheet, followed by a lock cycle.

Primary uses for molybdenum include steel alloys, industrial tools, electrical contacts, high temperature applications, and lubricants. Harris noted moly plays an important role in the green energy transformation. Moly is used extensively in wind turbines.

Mining financier and philanthropist Frank Giustra has purchased an 11.2% stake in Copper Giant. Giustra co-founded Aris Mining in Colombia. The company operates two underground gold mines, with Q2 2025 revenue of $200 million, up 75% from Q2 2024, driven by higher gold prices.

Mocoa remains open in all directions, with several satellite targets identified. These features support the interpretation of a district-scale porphyry system and position Mocoa as one of the most significant undeveloped copper-molybdenum assets in the Andes.

Edwin Naranjo Sierra, Vice-President of Exploration for Copper Giant, is the designated Qualified Person and has reviewed and approved the technical information in the news release.
