COSA RESOURCES CORP.

Cosa Resources is a Canadian uranium exploration company operating in northern Saskatchewan. The portfolio comprises roughly 237,000 ha across multiple 100% owned and Cosa operated Joint Venture projects in the Athabasca Basin region, all of which are underexplored, and the majority reside within or adjacent to established uranium corridors. Cosa’s award-winning management team has a long track record of success in Saskatchewan. In 2022, members of the Cosa team were awarded the AME Colin Spence Award for their previous involvement in discovering IsoEnergy’s Hurricane deposit. Prior to Hurricane, Cosa personnel led teams or had integral roles in the discovery of Denison’s Gryphon deposit and 92 Energy's Gemini Zone and held key roles in the founding of both NexGen and IsoEnergy. Cosa’s primary focus through 2024 was initial drilling at the 100% owned Ursa Project, which captures over 60-kilometres of strike length of the Cable Bay Shear Zone, a regional structural corridor with known mineralization and limited historical drilling. In November of 2024, the Company announced a transformative strategic partnership with Denison Mines that has secured Cosa access into several additional highly prospective eastern Athabasca projects while offering Denison Mines exposure to Cosa’s potential for exploration success and pipeline of potentially ISR-amenable uranium deposits.
