Edge Copper Reports New Oxide Drill Results at Zonia

Edge Copper Corporation (EDCU) has reported assay results for eight additional diamond drill holes at its Zonia copper project in Arizona, bringing the total number of reported holes to 45 out of the approximately 54,000-foot drilling program.

The company highlighted principal hole ZND0030, located in the central deposit, which returned 140 feet at 0.45% CuT from surface, including 80 feet at 0.63% CuT from 20 feet. The same hole also intersected 340 feet at 0.30% CuT from 400 feet, including 165 feet at 0.40% CuT from 410 feet.

At the northwestern margin beyond the Preliminary Economic Assessment (PEA) design pit, hole ZND0060 returned 248 feet at 0.30% CuT from 553 feet, including 156 feet at 0.37% CuT.

In the northern area, hole ZND0034 returned 465 feet at 0.26% CuT, ZND0039 returned 623 feet at 0.23% CuT, and ZND0041 returned 540 feet at 0.22% CuT.

Other reported intercepts included ZND0021 at 186 feet of 0.33% CuT, ZND0038 at 332 feet of 0.15% CuT, ZND0040 at 484 feet of 0.16% CuT, and a shallow 50 feet at 0.17% CuT in ZND0060.

The release frames these results as supporting geological and resource model updates, with an updated oxide Mineral Resource estimate targeted for the fourth quarter of 2026. All intervals use a 0.10% CuT cutoff.

Edge Copper Corporation (EDCU) is a pre-resource developer with a Preliminary Economic Assessment but no reserves, with its equity currently trading near the low end of its 52-week range. The company’s latest release features infill and resource-definition drilling inside and near the known deposit, along with one step-out hole on the northwestern margin.

The reported intercepts are at or above the existing resource grade, confirming the geological model and modestly de-risking the Zonia oxide resource. While one beyond-pit interval, ZND0060, extends the system modestly at 0.30% Cu, the release does not clearly expand the mineralized footprint in a way that alters the current PEA-scale thesis. The market appears to already be pricing in broad continuity and scale, meaning these holes do not provide a new high-grade discovery or a major step-out catalyst.

Edge Copper Corporation (EDCU) is a Canadian-listed copper exploration and development company trading on the TSX Venture Exchange. Its principal asset is the 100%-owned Zonia Copper Project in Yavapai County, Arizona, a past-producing heap-leach SX/EW operation located on patented and private land.

As of January 2026, the company reported a mineral resource of 194 million tonnes (Mt) indicated at 0.25% copper (Cu) for 964 million pounds (Mlb) contained copper, and 86 Mt inferred at 0.20% Cu for 341 Mlb. A preliminary economic assessment (PEA) completed in March 2026, based on a base case of US$4.60/lb Cu, outlined a 10-year mine life with an average production of 76 Mlb/year of copper cathode. The project features an average mined grade of 0.25% Cu, C1 cash costs of US$2.15/lb, and initial capital expenditures of approximately US$525M. The base case yielded an after-tax net present value (NPV8) of US$488M and an after-tax internal rate of return (IRR) of 23.4%.

At the last available price of C$0.50 and with approximately 167.4 million shares outstanding, the company’s market capitalization is roughly C$84M. Financial results for the six months ended June 30, 2026, showed a net loss of US$12.4M and cash holdings of about US$14.8M. The company reported zero debt but issued an explicit going-concern warning. Key shareholders include CEO Gil Clausen and GeologicAI, which also serves as a technical partner on the drill program.
