Edge Copper's TSX Debut Brings $488M Valuation to Zonia Project

Edge Copper Corporation (TSX:EDCU) made its debut on the Toronto Stock Exchange (TSX) on August 5, 2026, with a preliminary economic assessment (PEA) that values its Zonia Copper Project in Arizona at an after-tax net present value of US$488 million. The PEA was released in March 2026 and provides a baseline valuation for Zonia, which is currently being drilled to expand the resource and prepare an updated estimate.

According to the study, the proposed open-pit mine will feed a heap leach and solvent extraction and electrowinning (SX/EW) plant producing copper cathode on site. The planned facility is described as closed-circuit and zero-discharge. The base-case copper price used in the study was US$4.60/lb, with a domestic premium of US$0.04/lb.

The study estimates an after-tax NPV at an 8% discount rate of US$488 million, with an after-tax internal rate of return (IRR) of 23.4%. The payback period is estimated to be four years, and the life-of-mine free cash flow is expected to be around US$1.0 billion.

Edge Copper's leadership team includes Gil Clausen as chair and chief executive, Letitia Wong as president, and Patricia Fong as chief financial officer. The company is currently running a drill programme of about 54,000 ft that began in January 2026, with new oxide results reported on September 14, 2026.

The TSX graduation marks an important milestone for Edge Copper, making its shares accessible to a broader range of institutional investors. However, the company's progress will depend on future studies and drilling results, which could affect capital costs, recoveries, and mine design.
