Welcome to
Cosa Resources
Corp.

The uranium bull market is here. Early-stage explorers run by proven teams offer great upside potential through exposure to possible new discoveries of world class deposits in one of the top districts for uranium exploration and development - Saskatchewan's Athabasca Basin.

Cosa Resources is a Canadian uranium exploration company operating in northern Saskatchewan. The portfolio comprises roughly 237,000 ha across multiple underexplored 100% owned and Cosa-operated Joint Venture projects in the Athabasca Basin region, the majority of which 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 GMZ zone and held key roles in the founding of both NexGen and IsoEnergy.

In January of 2025, the Company entered a transformative strategic collaboration with Denison Mines that has secured Cosa access into several additional highly prospective eastern Athabasca uranium exploration projects and offers strong corporate, financial, and technical support from Denison. As Cosa’s largest shareholder, Denison gains exposure to Cosa’s potential for exploration success and its pipeline of uranium projects.

The Company’s core focus throughout 2025 is drilling at the Murphy Lake North Joint Venture. Murphy Lake North is a 70/30 Joint Venture between Cosa and Denison respectively and is located at the northern end of the Larocque Lake trend. The Project is within three kilometres of and on trend with the Hurricane deposit. Initial drilling completed by Cosa during winter 2025 intersected broad zones of hydrothermal alteration of the sandstone, associated with prospective basement structures interpreted as the strike extension of those controlling the Hurricane deposit. An expanded follow up campaign is currently in planning for the summer season.
