MACLAREN MINERALS ACQUIRES SANKAMAP PROPERTIES IN THE SOLOMON ISLANDS

Not for distribution to United States newswire services or for

dissemination in the United States.

Vancouver, British Columbia, February 19, 2025, Maclaren Minerals Ltd. (CSE:MRN) (the "Company") is pleased to announce that, further to its news release dated February 6, 2025, it has completed the acquisition of a 100% interest in Sankamap Exploration Inc. ("Sankamap"). The Sankamap properties include the Fauro Gold (Au) Project ("Fauro") and the Kuma Copper-Gold (Cu-Au) Project ("Kuma"), both located in the Solomon Islands along the same trend as significant Cu-Au porphyry and epithermal deposits, including Newmont's Lihir Mine (71.9 Moz Au1) and the Panguna Mine (19.3 Moz Au + 5.3 Mt Cu2) (the "Acquisition").

The 4,300-hectare Kuma project is situated 37 km southeast of Honiara, the capital city of Guadalcanal Island, Solomon Islands. Historical exploration at Kuma has identified large-scale Cu-Au mineralization and promising indicators of a potential porphyry deposit, which remains untested by drilling. The 14,700-hectare Fauro project is located on Fauro Island in northern Solomon Islands; past exploration has defined epithermal-type mineralization, with trenching results of up to 8 meters of 27.95 g/t Au and drilling intercepts of up to 11 meters of 4.03 g/t Au.

New Maclaren CEO John Florek commented: "This acquisition presents a unique opportunity to capitalize on two projects within an underexplored trend in the circum-Pacific region, renowned for its potential for giant Cu-Au mines. This trend hosts world-class porphyry and epithermal Cu-Au deposits, with Lihir and Panguna located along the same structural corridor. Lihir, in particular, is considered the world's richest gold deposit, with an estimated 71.9 million ounces (Moz) of gold1. We are excited to explore both of these project areas."

The Acquisition was completed by way of the acquisition of all the outstanding equity interests of Sankamap, a private arm's length British Columbia company which holds the interest in the Sankamap properties. Pursuant to the definitive agreement dated February 6, 2025, the Company issued 16,625,000 common shares in the capital of the Company (each, a "Consideration Share") to the shareholders of Sankamap in exchange for all the issued and outstanding common shares of Sankamap at a deemed price of $0.06 per Consideration Share for total deemed consideration of $997,500. The Acquisition is an arm's length transaction. No finder's fee was paid in connection with the Acquisition. The Consideration Shares are subject to a hold period pursuant to the CSE whereby the Consideration Shares may not be traded before the later of: (a) June 20, 2025; and (b) the date that is ten days after the Company files a business acquisition report on Form 51-102F4 in connection with the Acquisition.

Upon closing of the Acquisition, John Florek, CEO of Sankamap, was appointed CEO of the Company, replacing incumbent CEO Gary Musil, and John Alcock and Jim Greig were appointed to the Company's board of directors, replacing James Place and Dianne Szigety, and joining incumbent directors Gary Musil and Nancy Kawazoe. Upon closing, the Company's audit committee is comprised of Gary Musil, John Alcock and Jim Greig.

None of the securities issued in connection with the Acquisition will be registered under the United States Securities Act of 1933, as amended (the "1933 Act"), and none of them may be offered or sold in the United States absent registration or an applicable exemption from the registration requirements of the 1933 Act. This press release shall not constitute an offer to sell or a solicitation of an offer to buy nor shall there be any sale of the securities in any state where such offer, solicitation, or sale would be unlawful.
