Copper Giant expands Mocoa resource footprint and advances Connector Zone toward La Estrella, Colombia
Copper Giant Resources Corp. [TSXV: CGNT; OTCQB: LBCMF; FRA: 29H0] reported assay results from directional daughter holes MD-061 and MD-062 at its flagship Mocoa copper-molybdenum porphyry project in Putumayo, Colombia.
Mocoa is a Jurassic-age porphyry Cu–Mo deposit where drilling to date has delineated continuous copper and molybdenum mineralization from surface to depths exceeding 1,100 vertical metres. Hole MD-062 returned 258 metres of 0.70% CuEq (0.38% Cu and 0.06% Mo), above the current MRE average of 0.51% CuEq (0.31% Cu and 0.039% Mo), confirming the continuity and grade of higher-grade domains within the resource model ahead of PEA-level studies.
Hole MD-061, drilled in an area previously modelled as waste below the current conceptual pit design, returned 291 metres of 0.50% CuEq (0.27% Cu and 0.044% Mo), extending mineralization southward into the corridor between Mocoa and La Estrella where the Company’s third drill rig is now conducting maiden drilling from the La Estrella end.
MD-062 intersected 411 metres of 0.56% CuEq (0.31% Cu and 0.05% Mo) from the kick-off point, including 258 metres of 0.70% CuEq (0.38% Cu and 0.06% Mo) from 356 metres depth, above the current MRE average of 0.51% CuEq (0.31% Cu and 0.039% Mo), confirming the continuity and predictability of higher-grade domains within the current resource model.
MD-061 intersected 291 metres of 0.50% CuEq (0.27% Cu and 0.044% Mo) from 557 metres depth within 707 metres of continuous mineralization from the kick-off point, in an area previously modelled as waste below the current conceptual pit design, advancing the southern expansion vector into the Mocoa–La Estrella corridor.
The company’s third drill rig is conducting maiden drilling at La Estrella, testing the target from the southern end of the corridor. Three drill rigs operating on site at full capacity.
“These results advance both ends of the same story. MD-062 confirms that the high-grade domains we modelled are exactly where we expected them, that gives us confidence in the model as we move toward the PEA. MD-061 takes us beyond the current resource boundary and into the corridor toward the La Estrella, where our third rig is now drilling from the other end. We are building a picture hole by hole, and it is coming into focus, commented Edwin Naranjo Sierra, Vice-President of Exploration.
Hole MD-061 was drilled as a directional daughter hole from mother hole MD-056 to continue evaluating 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 and MD-058, which progressively identified stronger mineralization along the southern margin of the current MRE footprint. Historically, this area was only sparsely tested by shallow and sub-vertical drilling completed by Ingeominas and the United Nations, leaving the deeper extent and continuity of the system largely unconstrained.
MD-061 returned broad and continuous intervals of copper and molybdenum mineralization below the current conceptual pit design, including 707-metres of 0.37% CuEq (0.20% Cu and 0.032% Mo) starting from kick-off point, with grades increasing at depth with 291 metres of 0.50% CuEq (0.27% Cu and 0.044% Mo) starting from 557 metres.
These results continue to demonstrate that mineralization along the southern margin remains open and is strengthening toward the La Estrella target area immediately south of the current MRE footprint, while potentially contributing additional mineralized material currently outside the existing resource model. This evolving trend is increasingly supporting the interpretation of a broader mineralized corridor linking the southern extent of Mocoa with the emerging La Estrella target, where drilling is currently underway with the Company’s third drill rig. Drilling is now advancing toward the same corridor from both directions, while MD-061 continues to push mineralization southward from the Mocoa deposit, the Company’s third drill rig is actively drilling northwest from La Estrella, testing the emerging connection between both systems.
Drill hole MD-062 was completed as a directional daughter hole from previously reported mother hole MD-057, as part of the company’s ongoing infill drilling and resource conversion strategy within the current MRE footprint. Similar to previously reported daughter holes MD-059 and MD-060, the hole targeted areas characterized by wider historical drill spacing with the objective of increasing geological confidence and validating the continuity of modeled higher-grade domains ahead of future PEA-level studies.
The directional drilling approach continues to demonstrate significant operational advantages by allowing multiple targets to be efficiently tested from a single platform while reducing surface disturbance and improving geological control.
MD-062 successfully intersected long and continuous intervals of copper and molybdenum porphyry mineralization typical of the Mocoa system (Figure 4C – F), returning 411-metres of 0.56% CuEq (0.31% Cu and 0.05% Mo), including 258-metres of 0.70% CuEq (0.38% Cu and 0.06% Mo).
The results are consistent with, and locally exceed, grades predicted by the current MRE block model, further validating the company’s geological interpretation and the spatial predictability of higher-grade domains within the deposit. Importantly, these results continue to demonstrate that the current resource model is effectively predicting both grade distribution and mineralized continuity in areas of tighter drill spacing, supporting the ongoing advancement of Mocoa toward future engineering and PEA-level evaluation.
The Mocoa Project is located in Colombia’s Department of Putumayo, approximately 10 km from the town of Mocoa in the country’s south. Copper Giant controls more than 128,300 Ha of district-scale tenure through granted titles and applications, covering a significant portion of the Jurassic porphyry belt—an underexplored and highly prospective metallogenic corridor within the northern Andes.
Mocoa was first identified in 1973 through a regional geochemical survey conducted by the United Nations and the Colombian government. Follow-up programs between 1978 and 1983 included geological mapping, IP and magnetic geophysics, surface sampling, drilling, and metallurgical testing. Subsequent drilling by B2Gold in 2008 and 2012 refined the geological interpretation and confirmed the large scale of the system.
Mocoa exhibits classic porphyry-style zonation with a potassic core surrounded by sericite and propylitic alteration. Mineralization consists principally of disseminated chalcopyrite and molybdenite, accompanied locally by bornite and chalcocite, and is associated with stockwork veining and hydrothermal breccias.
A distinguishing geological feature of Mocoa is the presence of a fertile magmatic window spanning roughly 10 million years, a prolonged and unusually productive interval of magma generation and evolution that is not commonly observed in other Jurassic porphyry systems within the same belt. This extended fertile period provides a compelling explanation for the system’s large metal endowment, broad alteration footprint, and overlapping intrusive and hydrothermal events.
The deposit demonstrates more than 1,100 metres of vertical continuity, with multiple intrusive phases, brecciation episodes, and vein generations reflecting a dynamic and long-lived magmatic–hydrothermal evolution, likely influenced by more than one porphyry center. Mocoa remains open in all directions, and several satellite targets across the broader land package support the interpretation of a district-scale mineralized system.
Mocoa’s Mineral Resource Estimate1 comprises Inferred resources of 12.7 billion pounds (Blbs) copper-equivalent (CuEq) at an average grade of 0.51% CuEq, including 7.7 Blbs of copper at 0.31% Cu and 1.0 Blbs of molybdenum at 0.039% Mo, within 1,120 million tonnes (Mt).
Copper Giant Resources is part of the Fiore Group, a private and well-established Canadian organization known for building successful, high-impact companies across the natural resource sector.
Copper Giant’s current focus is the Mocoa copper-molybdenum deposit in southern Colombia, one of the largest undeveloped resources of its kind in the Americas.
