These reports will be based on publicly available information, industry data and direct discussions with the company's management, and are expected to provide investors with detailed, third party analysis of Canterra's assets and exploration strategy. Additionally, Atrium will conduct and host two recorded interviews with Canterra's management team to present the investment case and upcoming exploration catalysts to a broader audience.

For these research services, Atrium will receive a cash compensation of $12,000 per quarter, payable quarterly in advance. The agreement is for a period of 12 months, commencing on March 15, 2026. Following this initial term, the agreement will automatically extend on a quarter-to-quarter basis at the same compensation rate, unless otherwise mutually agreed upon or terminated by either party. This engagement is contingent upon the approval of the TSX Venture Exchange.

Canterra and Atrium are independent entities. Neither Atrium nor its insiders currently hold any shares or options to acquire shares in the issued and outstanding capital of the company. Atrium is an arm's-length party to the company.

About Canterra Minerals Corp.

Canterra is a diversified minerals exploration company focused on critical minerals and gold in central Newfoundland. The company's projects include seven mineral deposits located in close proximity to the world-renowned, past-producing Buchans mine and Teck Resources' Duck Pond mine, which collectively produced copper, zinc, lead, silver and gold. Several of Canterra's deposits support current and historical mineral resource estimates prepared in accordance with National Instrument 43-101 and the Canadian Institute of Mining, Metallurgy, and Petroleum Definition Standards for Mineral Resources and Mineral Reserves. Canterra's gold projects are located on trend of Equinox Gold's Valentine mine and cover an approximately 55-kilometre extension of the same structural corridor that hosts gold mineralization within Equinox Gold's mine. Past drilling by Canterra and others within the company's gold projects intersected multiple occurrences of orogenic-style gold mineralization within a large land position that remains underexplored.
