Copper Giant extends mineralization below pit at Mocoa; confirms third corridor

Canada NewsWire Deep infill hole MD-064 returns 1,052 metres of mineralization, including 486 m of 0.57% CuEq* (0.41% Cu and 0.029% Mo) , exceeding the 0.51% resource average; directional daughter hole MD-063 extends mineralization at depth toward   La   Estrella VANCOUVER, BC , June 22, 2026 /CNW/ - Copper Giant Resources Corp. ( "Copper Giant" or the "Company" ) (TSXV: CGNT) (OTCQB: LBCMF) (FRA: 29H0) today reports assay results from deep infill hole MD-064 and directional daughter hole MD-063 at its flagship Mocoa copper-molybdenum porphyry project in Putumayo, Colombia. These results continue to validate the model behind the Company's 1.12 Bt Inferred resource 1 containing 12.7 Blbs of CuEq* (7.7 Blbs of copper at 0.31% Cu and 1.0 Blbs of molybdenum at 0.039% Mo). MD-064 intersected 1,052 metres of continuous mineralization, including 486 metres of 0.57% CuEq* (0.41% Cu and 0.029% Mo), exceeding the current MRE 1 average of 0.51% CuEq* and validating the grade and continuity predicted by the resource model ahead of the Preliminary Economic Assessment (PEA).

The hole also delivered the first modern confirmation of the western breccia, establishing a third drill-tested mineralized breccia corridor at Mocoa and supporting the interpretation of a large, multi-phase porphyry system with multiple mineralized centers. MD-063 extended continuous mineralization below the current conceptual pit, through ground previously modelled as waste, confirming that the system continues at depth and to the south toward the corridor with La Estrella, where the Company's third drill rig is conducting maiden drilling from the other end. Together the results increase geological confidence in the resource model and set expectations of potential additional resource growth ahead of the planned upcoming PEA.
