Plata Latina and World Copper Announce Acquisition of the Zonia Project by

Plata Latina and Concurrent $17 Million Financing to Create

a Development-Focused Copper Company to be Named “Edge Copper Corporation”

THIS NEWS RELEASE IS INTENDED FOR DISTRIBUTION IN CANADA ONLY AND IS NOT INTENDED FOR DISTRIBUTION TO

UNITED STATES NEWSWIRE SERVICES OR FOR DISSEMINATION IN THE UNITED STATES.

All dollar amounts in this news release refer to Canadian dollars.

Vancouver, British Columbia – July 23, 2025 – Plata Latina Minerals Corporation (TSXV: PLA)

(“Plata Latina”) and World Copper Ltd. (TSXV: WCU, OTCQB: WCUFF, FSE: 7LY0) (“World

Copper”) are pleased to announce that they have entered into a n arm’s length definitive

agreement dated July 22, 2025 (the “Transaction Agreement”) for Plata Latina to acquire the

Zonia Copper Project (“Zonia”) in Arizona from World Copper for consideration of cash and

common shares of Plata Latina (“ Plata Latina Shares”) by way of a court -approved plan of

arrangement (the “Transaction”). 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 (the “ Cash

Consideration”) 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 “Share

Consideration”). 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 (the “World Copper Shares”)(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 (the “Exchange Ratio”) 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 (“Plata Latina

Units”) at a price of $0.10 per Plata Latina Unit for gross aggregate proceeds of $17 million (the

“Concurrent Financing ”). 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 Wor ld 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 e xperienced 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 7th

globally on mining investment attractiveness , according to the Fraser Institute’s 2023

Annual Survey of Mining Compa nies. 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.

Plata Latina Governance and Leadership

Following closing, Plata Latina will appoint two World Copper directors, currently expected to be

Robert Kopple and Keith Henderson, to its current board of directors (the “Plata Latina Board”).

Plata Latina’s senior leadership team will include Gilmour Clausen as Chair and Chief Executive

Officer and Letitia Wong as President.
