Copper Giant Intersects 135 Metres of 1.60% CuEq* (1.02% Cu and 0.107% Mo) Within 724 Metres of 0.78% CuEq* at Mocoa

Copper Giant Resources Corp. (CGNT) has released assay results from three drill holes across two platforms at its Mocoa Cu-Mo porphyry project in Putumayo, Colombia. The company confirmed that none of these holes were included in the Updated Mineral Resource Estimate (MRE) dated October 14, 2026, which is effective as of September 24, 2026.

Key reported intervals include:

• MD-074, mother hole, 0-903 m: 903 m @ 0.41% Cu, 0.041% Mo, 0.63% CuEq.
• MD-074: 724 m @ 0.51% Cu, 0.050% Mo, 0.78% CuEq from 179 m.
• MD-074: 355 m @ 0.66% Cu, 0.069% Mo, 1.04% CuEq from 305 m.
• MD-074: 135 m @ 1.02% Cu, 0.107% Mo, 1.60% CuEq from 474 m.
• MD-074: 52 m @ 1.36% Cu, 0.164% Mo, 2.24% CuEq from 557 m.
• MD-074: separate 213 m @ 0.38% Cu, 0.038% Mo, 0.58% CuEq from 690 m, including 41 m @ 0.87% CuEq from 862 m.
• MD-076, directional daughter from MD-074: 637 m @ 0.28% Cu, 0.016% Mo, 0.37% CuEq from 145 m.

• MD-076: 30 m @ 0.76% CuEq from 411 m and a separate 67 m @ 0.51% Cu, 0.028% Mo, 0.66% CuEq from 636 m.
• MD-075, mother hole on the northern side: 1,058 m @ 0.18% Cu, 0.018% Mo, 0.28% CuEq whole hole.
• MD-075: 699 m @ 0.25% Cu, 0.024% Mo, 0.38% CuEq from 356 m.
• MD-075: 208 m @ 0.59% CuEq from 483 m, 108 m @ 0.69% CuEq from 533 m, 28 m @ 0.92% CuEq from 538 m.
• MD-075: separate deep interval 123 m @ 0.17% Cu, 0.031% Mo, 0.33% CuEq from 900 m, within potassic alteration logged from 826 m.

Assays remain pending for holes MD-072, MD-077, MD-078, and MD-079. Copper Giant Resources Corp. expects to release a Preliminary Economic Assessment (PEA) based on the Updated MRE by the end of November 2026.

Copper Giant Resources Corp. (CGNT) has released drill results from its Mocoa project, marking a significant step in the exploration of the large, defined resource body. As a pre-revenue explorer and developer, the company’s valuation must be assessed against its equity position and the market’s prior pricing, rather than through the lens of current production earnings.

The latest data centers on the high-grade drilling program at Mocoa. On September 22, 2026, hole MD-073 returned 804 m @ 0.56% CuEq, including 103 m @ 1.07% CuEq. Earlier, on August 27, 2026, hole MD-070 returned 771 m @ 0.54% CuEq, including 102 m @ 0.87% CuEq. The most recent result, MD-074, demonstrated higher grades and a greater length of high-grade material, returning 724 m @ 0.78% CuEq and 135 m @ 1.60% CuEq, with a 52 m @ 2.24% core. While the broad interval of MD-074 is shorter than the 804 m reported in MD-073, the strength in grade and high-grade substance represents a positive development.

Copper Giant Resources Corp. shares have experienced significant volatility. The stock traded at C$0.26 in late October 2025 before peaking at C$1.46 on September 8, 2026. It closed at C$1.41 on September 22, coinciding with the MD-073 report. By October 26, 2026, the price had fallen to C$0.91, dropping below the reaction to the October 14 Mineral Resource Estimate (MRE) and sitting approximately 38% below the 52-week high. This pullback suggests that the market has not fully priced in the specific results from the latest drilling campaign.

The new drilling does not constitute a game-changing discovery, as the holes remain within the known Mocoa system and the conceptual pit shell. While the results improve the high-grade narrative and support resource conversion, they do not independently open a new district, intrusive center, or depth dimension. Hole MD-076, a step-out to the west, returned 67 m @ 0.66% CuEq but is not considered district-opening. Similarly, MD-075 identified a potassic vector that is geologically significant but does not yet represent an economic interval. The Preliminary Economic Assessment (PEA), scheduled for release in November, is based on the Updated MRE and excludes these specific holes, limiting the near-term impact on net asset value until the high-grade zone is incorporated into the resource and mine planning.

At a market capitalization of approximately C$233 million, Copper Giant Resources Corp. is not a micro-cap and already holds a large resource and strategic partnerships. While a single infill or step-out hole can drive share price movement, particularly following a pullback, it does not typically re-rate the entire business unless it fundamentally alters the resource scale or PEA economics. The current release is strong enough to potentially trigger a positive share-price reaction, but it does not transform the underlying investment thesis.

Copper Giant Resources Corp. (CGNT) is a TSXV-listed junior focused on the Mocoa Cu-Mo porphyry project in Putumayo, Colombia. Mocoa is a Jurassic porphyry system with more than 1,100 m of vertical continuity, multiple intrusive phases, breccia corridors and classic porphyry alteration. The company controls more than 128,300 hectares of district-scale tenure in the Jurassic porphyry belt.

The Updated MRE, effective September 24, 2026, reports Indicated resources of 0.29 Bt @ 0.54% CuEq (0.33% Cu, 0.038% Mo), containing 2.13 Blb Cu and 0.24 Blb Mo, and Inferred resources of 1.60 Bt @ 0.40% CuEq (0.27% Cu, 0.025% Mo), containing 9.36 Blb Cu and 0.89 Blb Mo. Pit-constrained resources use a 0.15% CuEq cut-off; below-pit resources use 0.40% CuEq. The PEA is due by end-November 2026.

The company also signed a special exploration and exploitation contract for the 1,614.73-hectare Chaparral block in Tolima, about 306 km northeast of Mocoa. That block is early-stage, with no resource and no company exploration yet. It adds optionality but not near-term value.

Strategic context: Denarius Metals holds about 15.34% after a C$31 million placement at C$0.72, and Trafigura has a 10-year offtake for 20% of copper and molybdenum concentrate production. Prior-period context — not disclosed in today's release: Q1-2026 cash was C$21.2 million, the company reported a net loss of C$11.5 million, and the MD&A carried a going-concern qualification. The company is pre-revenue and dependent on equity financing.
