Edge Copper Intersects 287 ft at 0.73% Total Copper, including 190 ft at 1.01% Total Copper, at Zonia
Edge’s Zonia oxide copper hit reached its best yet, though cash needs temper the potential for a share price re-rate.
Edge Copper Corporation (EDCU) reported assay results from ten additional diamond drill holes at its 100%-owned Zonia Copper Project in Arizona, bringing the total number of reported holes in the current program to 37. Principal hole ZND0032, drilled as an undercut beneath shallow historical holes in the central deposit, returned 287 ft at 0.73% total copper from 13 ft, including 190 ft at 1.01% CuT. The same hole also returned 252 ft at 0.26% CuT from 350 ft, including 112 ft at 0.41% CuT, and 168 ft at 0.26% CuT from 642 ft, including 50 ft at 0.35% CuT.
Other highlighted holes include ZND0058 with 165 ft at 0.46% CuT including 104 ft at 0.64% CuT, ZND0005 with 188 ft at 0.55% CuT from 2 ft, and ZND0052 with 522 ft at 0.15% CuT including 40 ft at 0.47% CuT. The company uses a 0.10% total copper cutoff, reports approximate true thicknesses based on drill geometry orthogonal to interpreted foliation and faults, and used Skyline Assayers and Laboratories for analysis. The release frames ZND0032 as the highest-grade interval intersected to date in the current program and as evidence of oxide mineralization over roughly 550 ft of true vertical extent in the central deposit area.
Edge Copper Corporation (EDCU) is a development-stage explorer with an existing Preliminary Economic Assessment (PEA) and resource base, distinguishing it from pre-resource wildcats. Consequently, infill and step-out drilling inside and around its known deposit carries economic weight if it can improve grade or add leachable tonnage. The principal intercept reported is genuinely new and positively differentiated from previous results, representing the highest-grade broad oxide interval in the current program.
The company’s current market price of C$0.54 sits well below the January 2026 high of C$1.03 and also below the June 2026 financing price of C$0.58, indicating that the market is not embedding an aggressive discovery-style expectation. While prior strong holes did not hold the stock level, the main driver of future valuation is whether drilling and the Q4 2026 resource update prove high-grade leachable tonnes, rather than this single hole alone.
Financial context from the latest interim filings shows cash of US$14.8 million at June 30, 2026, a net loss of US$12.4 million for H1 2026, and an explicit going-concern statement.
Edge Copper Corporation (EDCU) is a copper-focused exploration and development company listed on the TSX Venture Exchange. Its sole material asset is the 100%-owned Zonia Copper Project in Yavapai County, Arizona, which is a past-producing heap leach operation situated on private and patented land.
The company’s January 2026 mineral resource estimate identified 194 million tonnes of indicated resources grading 0.25% copper for 964 million pounds of contained copper, alongside 86 million tonnes of inferred resources grading 0.20% copper for 341 million pounds of contained copper. A preliminary economic assessment (PEA) completed in March 2026 outlined an open-pit heap leach solvent extraction-electrowinning (SX/EW) operation. This plan projects annual production of 76 million pounds of copper cathode over a 10-year mine life. At a copper price of US$4.60 per pound, the PEA calculated an after-tax net present value (NPV) of US$488 million and an internal rate of return (IRR) of 23.4%.
Initial capital costs in the PEA were estimated at US$524.5 million. The assessment assumed an average mined copper grade of 0.25% and an average recovery rate of 72.8%. As of June 30, 2026, the company reported US$14.8 million in cash, no debt, negative operating cash flow, and no revenue.
