Plata Latina Minerals Corporation (TSX-V: PLA) and World Copper Ltd. (TSX-V: WCU) (OTCQB: WCUFF) (FSE: 7LY0) are pleased to announce that they have entered into an arm’s length definitive agreement dated July 22, 2025 for Plata Latina to acquire the Zonia Copper Project in Arizona from World Copper for consideration of cash and common shares of Plata Latina by way of a court-approved plan of arrangement.  Plata Latina will be renamed Edge Copper Corporation upon closing of the Transaction.

Under the terms of the Transaction, World Copper will receive $10.5 million in cash  and such number of Plata Latina Shares as results in World Copper and its shareholders owning approximately 31.3% of Plata Latina, on a non-diluted basis, immediately following closing of the Transaction and the Concurrent Financing (as defined below).  The aggregate Cash Consideration and Share Consideration are valued at approximately $22 million, which implies a value of approximately $0.085 per common share of World Copper ⁽¹⁾ representing a premium of approximately 40% to the five-day volume-weighted average price of the World Copper Shares on the TSX Venture Exchange as of July 22, 2025 and a premium of approximately 71% to the 20-day volume-weighted average price of the World Copper Shares on the TSX Venture Exchange as of July 22, 2025.

As part of the Transaction, World Copper shareholders are expected to receive approximately 0.3930 of a Plata Latina Share for each World Copper Share pursuant to a distribution by World Copper to its shareholders of a substantial portion of the Share Consideration.⁽²⁾  Immediately following closing, World Copper will retain approximately $500,000 in cash and 15,000,000 Plata Latina Shares and will use the balance of the Cash Consideration to satisfy outstanding indebtedness, accounts payable and other liabilities of World Copper and its subsidiaries. World Copper shareholders will continue to hold their interest in World Copper, which is expected to remain a stand-alone public company, with a clean balance sheet, and a focus on continued exposure to the Cristal project – a prospective and high-potential Chilean porphyry copper deposit.  For further details regarding the Cristal project, please refer to World Copper’s press release of July 17, 2025, available under its profile on SEDAR+ at www.sedarplus.ca.

In connection with the Transaction, Plata Latina has entered into binding subscription agreements with investors pursuant to a non-brokered private placement of units of Plata Latina at a price of $0.10 per Plata Latina Unit for gross aggregate proceeds of $17 million. The proceeds of the Concurrent Financing are being allocated to finance the Cash Consideration and to fund exploration and development of Zonia, including drilling, metallurgical test work, feasibility study work and permitting work, and for general working capital and corporate purposes.  No commission or brokerage or finder’s fee is payable in connection with the Concurrent Financing.

As a result of the Transaction, Plata Latina expects to become a development-focused copper company poised to advance the 100%-owned Zonia Copper Project in Arizona.  Zonia is a past-producing conventional open-pit mine that is planned to produce pure copper cathode on-site. The planned operation is situated on private and patented lands, allowing for a faster and more streamlined permitting process, with considerable exploration upside on an additional 3,713 acres of unpatented claims to the northeast of the current mineral resource.

“The acquisition of Zonia is an important and significant step for Plata Latina and positions us well as the U.S. focuses on domestic demand for critical minerals,” commented Letitia Wong, President and Chief Executive Officer of Plata Latina. “With Zonia located on private and patented lands, the permitting process is expected to be more efficient and streamlined, enhancing project development certainty. Under the leadership of our highly experienced project team—recognized for its success in advancing copper projects in Arizona—we look forward to moving Zonia toward construction in the near to medium term.  We are excited about Zonia and the additional value we expect to bring to our shareholders, World Copper shareholders, and new investors in the Concurrent Financing.”

Gordon Neal, President and Chief Executive Officer of World Copper, stated: “The sale of Zonia to Plata Latina will provide significant value to World Copper shareholders. The Plata Latina team has a track record of creating value for shareholders by developing, operating, and ultimately vending copper and gold mines and assets to major resource industry players. World Copper shareholders will receive a significant share position in Plata Latina while maintaining their existing shares in World Copper. The new reconstituted World Copper will be a clean, debt-free and capitalized copper exploration company with a new Chilean asset.  This is a meaningful win for World Copper shareholders in an accelerating global copper market.”

Transaction Highlights

• Combines a seasoned management team with a strategic copper project in Arizona: The experienced management team has significant prior experience in Arizona and a strong track record of creating value through resource growth. Experience includes generating a 175% shareholder return and a 2.5x resource increase at Copper Mountain (sold to Hudbay in 2023), as well as generating a greater than 1,200% shareholder return and a 1.5x resource increase at Augusta Resource Corporation (sold to Hudbay in 2014).
• Strategically aligned acquisition provides attractive value proposition and re-rate upside potential: Following the Transaction, Plata Latina is expected to compare favourably to peers on key valuation metrics, providing upside and re-rate potential. Through their Share Consideration, World Copper shareholders will have the opportunity to participate in the potential re-rating as the Plata Latina management team executes its strategic vision for Zonia.
• A significant private land package presents a strong exploration opportunity for future value creation: There are over 900 hectares of private land at Zonia, which hosts a current resource that underpins 10 years of initial production. Limited historical exploration work has been completed which provides strong potential for resource expansion and larger-scale production. An additional BLM land package nearby provides significant potential for a Phase 2 expansion in the future.
• Zonia is located in a Tier 1 jurisdiction: Copper is a critical mineral to the U.S. and Zonia is strategically located in Arizona, the largest producer of copper in the U.S., ranked 7^th globally on mining investment attractiveness, according to the Fraser Institute’s 2023 Annual Survey of Mining Companies. The pre-stripped, past-producing Zonia benefits from existing infrastructure and a streamlined permitting process, which only requires state permits for Phase 1.
• Straightforward and low-risk Zonia project to become a primary asset for Plata Latina: Zonia’s oxide porphyry deposit is attractive and straightforward with conventional open pit mining at a brownfield site via SX-EW, which is expected to reduce processing, minimizing complexity and emissions.
• Retained exposure to Chilean assets with capital markets optionality for World Copper shareholders: World Copper shareholders will have the opportunity to participate in continued exposure to the Cristal project – a prospective Chilean porphyry copper deposit – in a vehicle with a clean balance sheet and cash and Plata Latina Shares, together with capital markets optionality to access further financing to advance exploration and development and a TSX Venture Exchange listing to serve as a viable RTO candidate.
