Copper Giant Intersects 103 Metres of 1.07% CuEq* (0.57% Cu and 0.095% Mo) Within 804 Metres of 0.56% CuEq* at Mocoa

Copper Giant Resources Corp. (CGNT) reported assay results from four holes at its Mocoa Cu-Mo porphyry project in Colombia: MD-073, a directional daughter from MD-064 with a kick-off at 150 m (azimuth 290°, dip -60°); MD-067, a mother hole drilled to 756 m; MD-071, a daughter from MD-067 with a kick-off at 166 m; and MD-069, a mother hole on the La Estrella platform drilled to 541 m.

Key intercepts included: - MD-073: 804 m at 0.56% CuEq (0.31% Cu, 0.048% Mo) from 150 m to 954 m; including 373 m at 0.74%, 199 m at 0.93%, 103 m at 1.07% CuEq (0.57% Cu, 0.095% Mo) from 346 m, and 54 m at 1.20% CuEq (0.64% Cu, 0.106% Mo) from 381 m. The hole ended in mineralization. - MD-067: Full-hole 756 m at 0.27% CuEq; 639 m at 0.31% CuEq from 117 m to bottom; including 242 m at 0.54%, 165 m at 0.67% (0.43% Cu, 0.046% Mo) from 191 m, 133 m at 0.74%, 13 m at 1.31% (0.92% Cu) from 201 m; separate 32 m at 0.27% from 708 m (Mo more than half the CuEq). - MD-071: 542 m at 0.34% CuEq over the full assayed length; including 184 m at 0.62% (0.33% Cu, 0.054% Mo) from 166 m, 110 m at 0.75%, 14 m at 1.15% (0.86% Cu) from 200 m; separate 78 m at 0.29% from 630 m to bottom (708 m). - MD-069: 541 m at 0.03% CuEq overall; best interval 12 m at 0.11% CuEq from 460 m. This hole is described as defining the Rancho Mula fault position.

Operationally, a fourth rig is on site for the western flank, drilling from October. The Preliminary Economic Assessment (PEA) remains on plan for Q4 2026. The material in MD-067 and MD-071 beyond and below the current Mineral Resource Estimate (MRE) is explicitly excluded from the MRE and the in-progress PEA.

Copper Giant Resources Corp. (CGNT) remains a pre-revenue explorer with a large but entirely Inferred resource and no mine plan yet. The company’s equity, valued at approximately C$333M on a basic basis, prices the scale of the resource, the probability of the Preliminary Economic Assessment (PEA) working, and continued resource conversion, rather than cash flow.

The stock has risen from C$0.19 on September 22, 2025, to C$1.30 on September 21, 2026, representing roughly a 7x increase. This current price sits 80% above the C$0.72 level at which Denarius and insiders purchased C$31M of stock in August 2026. The market has already priced in the Mineral Resource Estimate (MRE) released in November 2025, the strategic financing and offtake agreement in August 2026, and repeated drill releases from April through August 2026 that exceeded model grades. Additionally, the stock rose approximately 18% over the five trading sessions preceding this release, moving from C$1.10 to C$1.30, indicating that some anticipation is already embedded in the price.

For resource-definition holes, the correct benchmark is the resource grade rather than the best prior headline hole. Drill hole MD-073 returned 804 meters at 0.56% CuEq, which is above the 0.51% CuEq resource grade over a meaningful interval. This represents the strongest high-grade core of the current campaign.

Compared to the immediate prior campaign holes, the results are modestly better on percent-metres and high-grade core, while remaining broadly in line on overall grade. The results do not change the scale of the system, which is already 1.12 billion tonnes with more than 1,100 meters of vertical continuity and remains open. There is no new zone, no new intrusive centre, and no new resource milestone.

Conversely, MD-069 is a near-barren hole on the district target that the company has promoted since January as a potential second porphyry centre. The hole also shows the Rancho Mula fault truncating the section 225 meters from historic drilling at the southern margin.

The release confirms the model ahead of the PEA and adds technical confidence, but does not change what the market already assumes about size, grade, or odds. The La Estrella outcome removes some of the district optionality premium.

Copper Giant Resources Corp. (TSXV: CGNT, OTCQX: CGNRF, FRA: 29H0) is a pre-revenue junior explorer and part of the Fiore Group, led by CEO Ian Harris with Frank Giustra as a principal shareholder holding approximately 12-13% basic, and higher on a partially diluted basis. The company’s single flagship asset is the Mocoa Cu-Mo porphyry in the Putumayo Department of southern Colombia, located approximately 10 km from the town of Mocoa. It holds more than 128,300 hectares of district-scale tenure in the Jurassic porphyry belt, which also hosts the Mirador, Warintza, San Carlos, and Panantza deposits in the same broader corridor.

Geological studies indicate Middle Jurassic dacite and quartz-diorite porphyries intruding andesitic-dacitic volcanics. The site exhibits classic porphyry zonation with a potassic core, sericite and propylitic alteration, disseminated chalcopyrite and molybdenite with local bornite and chalcocite, stockwork veining, and hydrothermal breccias. The deposit shows more than 1,100 meters of vertical continuity and multiple intrusive phases suggesting more than one porphyry center.

An effective resource statement dated November 18, 2025, and filed on January 8, 2026, defines 1,120 million tonnes of Inferred resources at 0.51% CuEq at a 0.25% CuEq cut-off, pit-constrained. This totals 12.7 billion pounds of CuEq, comprising 7.7 billion pounds of copper at 0.31% Cu and 1.0 billion pounds of molybdenum at 0.039% Mo. The model assumptions include US$4.00 per pound for copper, US$20.00 per pound for molybdenum, 90% copper and 95% molybdenum recoveries, US$10 per tonne for processing, US$1 per tonne for general and administrative costs, and a 3% net smelter return.

De-risking efforts to date include two prior consultation agreements with nearby Indigenous communities: Montclar in 2022 and Inga Condagua, completed in September 2025, marking the first such agreement at the exploration stage in Colombia. Unified mining titles FJT-131 and FJT-141 were approved in April 2026 with no forestry-reserve overlap. Bench-scale metallurgy has achieved up to 92% copper and 97% molybdenum rougher recovery on a single 130 kg composite.

Strategic partners include Denarius Metals, which holds approximately 15.34% of the equity after investing C$28.8 million at C$0.72 in August 2026, funded by a concurrent Trafigura placement into Denarius. Trafigura holds a ten-year offtake agreement for 20% of copper concentrate and 20% of molybdenum concentrate production from Mocoa. Denarius, Giustra, and Harris all entered two-year lock-ups on the August 2026 shares.
