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 resource1 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 MRE1 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.
Highlights
- MD-064 confirmed continuity across the deposit: 1,052 metres of continuous mineralization from 155 metres, including 486 metres of 0.57% CuEq* (0.41% Cu and 0.029% Mo), exceeding the current MRE1 average of 0.51% CuEq*, with a higher-grade core of 115 metres of 0.65% CuEq* from 552 metres downhole (Table 1).
- Third mineralized breccia corridor confirmed: 180 metres of 0.44% CuEq*(0.36% Cu and 0.015% Mo), including 72 metres of 0.55% CuEq* (0.51% Cu and 0.008% Mo) (Table 1). Mocoa now comprises three drill-tested mineralized breccia corridors, consistent with a multi-phase porphyry system with multiple mineralized centers.
- MD-063 extended mineralization below the current conceptual pit through ground previously modelled as waste, returning 303 metres of 0.41% CuEq* (0.25% Cu and 0.031% Mo) within 808 metres of continuous mineralization (Table 1), confirming continuity at depth and to the south and pointing to potential resource growth and pit-design upside.
- The corridor toward La Estrella is being closed from both ends: MD-063 extends mineralization south and at depth, while the Company’s third rig conducts maiden drilling at La Estrella from the other end. Results pending.
- Multiple catalysts ahead: an updated MRE, second stage of metallurgical test, the planned upcoming PEA, and assay results from La Estrella provide a strong pipeline of near-term catalysts.
“These two holes do something more valuable than chasing a high number. MD-064 confirms the continuity and grade of the deposit across more than a kilometre of core, which leads us to believe the resource model we will build the PEA on is sound. MD-063 shows the system continuing below the current pit, in ground we had modelled as waste, and the first modern confirmation of the western breccia tells us Mocoa is a larger, multi-center system than the current resource captures. We are increasing confidence in what we have and adding to what is still to come, exactly what we want heading into the PEA.” – Edwin Naranjo Sierra, Vice-President of Exploration.
MD-063
Copper Giant uses directional drilling to steer multiple daughter holes from a single drill pad, testing several targets without building new pads or roads in Mocoa’s steep terrain. This delivers more geological information per metre at lower cost and with less surface disturbance, and it accelerates potential MRE conversion and expansion ahead of the PEA. Daughter holes are drilled to a planned length and are typically still in mineralization when completed by design. Hole MD-063 was drilled as a directional daughter hole from MD-056 to further evaluate the southern expansion potential of the Mocoa system below the current conceptual pit design. The hole forms part of a systematic follow-up to previously reported holes MD-054, MD-056, MD-058 and MD-061 (refer to news releases dated January 29, 2026, March 16, 2026, April 14, 2026 and May 20, 2026, respectively), which progressively identified stronger mineralization along the southern margin of the current MRE¹ footprint. Historically, this area was only sparsely tested by shallow and sub-vertical drilling, leaving the deeper extent and continuity of the system largely unconstrained.
