EDGE COPPER ANNOUNCES PARTIAL EXERCISE OF OVER-ALLOTMENT OPTION FOR PUBLIC OFFERING AND UPDATE ON CONCURRENT PRIVATE PLACEMENT

The underwriters of Edge Copper Corp.'s previously announced overnight marketed offering of 30,172,414 common shares at a price of 58 cents per common share have exercised the overallotment option in part to purchase an additional 2,575,000 common shares, on the same terms and conditions, on the closing date of the public offering, for additional proceeds to the company of $1,493,500, for total gross proceeds from the public offering of approximately $18,993,500.

Concurrently with the closing of the public offering, 6,974,747 common shares of the company will be sold in a non-brokered private placement to purchasers, including certain insiders of the company, at a price of 58 cents per common share, for gross proceeds of $4,045,353.

Aggregate gross proceeds from the public offering and the private placement are expected to be approximately $23,038,853.

The company proposes to use the net proceeds from the public offering and the private placement primarily to advance exploration and development of its wholly owned Zonia copper project in Arizona.

Insider participation in the private placement is a related-party transaction within the meaning of Multilateral Instrument 61-101 (Protection of Minority Securityholders in Special Transactions). Edge Copper relied on the exemption from formal valuation and minority shareholder approval requirements under Section 5.5(a) and 5.7(1)(a) of MI 61-101, respectively, as the fair value of the common shares issued to insiders under the private placement and the consideration paid by the insiders therefor do not exceed 25 per cent of Edge Copper's market capitalization. Closing of the public offering and the private placement is expected to occur on June 9, 2026, and is subject to receipt of customary regulatory approvals, including approval of the TSX Venture Exchange.
