EDGE COPPER ANNOUNCES COMPLETION OF THE ACQUISITION OF THE ZONIA COPPER PROJECT AND CONCURRENT $17 MILLION FINANCING TO CREATE "EDGE COPPER CORPORATION"

Edge Copper Corp. (formerly Plata Latina Minerals Corp.) has completed its previously announced acquisition of the Zonia copper project in Arizona from World Copper Ltd. (TSX Venture Exchange: WCU) (OTCQB: WCUFF) (FSE: 7LY0) in exchange for consideration of cash and common shares of Edge Copper by way of a court-approved plan of arrangement. In connection with the transaction, Plata Latina Minerals changed its name to Edge Copper Corp. and effected a 1:3 consolidation of its common shares.

It is anticipated that the Edge Copper shares will commence trading on the TSX-V on or about Nov. 3, 2025, on a postconsolidation and postname change basis under the new stock symbol EDCU with the Cusip and ISIN numbers 279852107 and CA2798521076, respectively.

"Zonia represents a remarkable opportunity to apply our technical expertise and modern mining approaches to a project with strong fundamentals," said Gil Clausen, Edge Copper's chair and chief executive officer. "With exceptional near-term exploration and development upside, existing infrastructure, private land tenure, and a supportive regulatory environment, our team sees clear potential to advance Zonia toward development efficiently and responsibly."

Edge Copper's president, Letitia Wong, commented: "The acquisition of the Zonia copper project marks a transformative step in establishing the new Edge Copper as the next leading U.S. copper developer. As global demand for copper continues to grow and the U.S. focuses on domestic demand for critical minerals, Edge Copper is focused on advancing projects that can deliver both economic and environmental value."

Under the terms of the transaction, Edge Copper acquired all of the issued outstanding common shares of World Copper's wholly owned subsidiary, Zonia Holdings Corp., which indirectly holds the Zonia copper project. World Copper received $10.5-million in cash and an aggregate of 37,820,374 Edge Copper shares (on a postconsolidation basis), resulting in World Copper and its shareholders owning approximately 31.3 per cent of Edge Copper, on a non-diluted basis, immediately following closing of the transaction and the concurrent financing (as defined below). As part of the transaction, World Copper shareholders received 0.12482512 of an Edge Copper share, on a postconsolidation basis, for each common share of World Copper pursuant to a distribution by World Copper to its shareholders of a substantial portion of the share Consideration. World Copper retained approximately $500,000 in cash and five million Edge Copper shares (on a postconsolidation basis), and is required to use the balance of the cash consideration to satisfy outstanding indebtedness, accounts payable and other liabilities of World Copper and its subsidiaries.

As a result of the transaction, Zonia Holdings has become a wholly owned subsidiary of Edge Copper. World Copper continues to be a stand-alone reporting issuer in all of the provinces and territories of Canada, with its common shares listed on the TSX-V under the stock symbol WCU. The transaction was completed on an arm's-length basis and no finders' fees were payable in connection with the transaction.
