Vanguard Mining Corp. (UUU: CSE | UUUFF: OTCID | SL51: Frankfurt) announced the completion of the acquisition of Quark Uranium Ltd. The acquisition was executed under the share exchange agreement dated April 22, 2026.

Under the terms of the agreement, Vanguard issued 8,000,000 common shares at a deemed price of $0.15 per share and made cash payments of C$200,000 for 100% of Quark's outstanding securities.

David C. Greenway, President and CEO of Vanguard Mining Corp., stated that the Quark acquisition strengthens Vanguard’s footprint in the Athabasca Basin, a major uranium district. He added that the company is excited to advance exploration on the property and deliver long-term shareholder value as nuclear energy demand increases.

The Quark Uranium property comprises eight mineral claims totaling approximately 28,746 hectares in Saskatchewan, Canada. It is located within a uranium-producing district near projects operated by Orano Canada and Fission Uranium Corp.

The properties are in the early stages of exploration and lack known mineral resources or reserves. The company believes the property is prospective based on its regional geological setting, but there is no guarantee that further exploration will lead to the discovery of economically recoverable mineralization. Mineralization on nearby properties does not necessarily indicate mineralization on the Quark Uranium property.

Lawrence Segerstrom, P.Geo., M.Sc., MBA, a consulting geologist and a “Qualified Person” as defined under National Instrument 43-101, has reviewed and approved the scientific and technical information in the release. Mr. Segerstrom is not independent of the Company.

Vanguard Mining Corp. is focused on discovering and developing strategic minerals. It is currently working on uranium exploration projects in the United States and Paraguay. The company focuses on responsible exploration and value creation through acquiring and advancing prospective uranium properties.
