Cosa Resources Expands Orbit Project on Pathfinder Gas Occurrences

Cosa Resources Expands Orbit Project Following Geochemical Anomalies

Cosa Resources Corp. (COSA.V) advanced following the announcement of an expanded Orbit Project in the southeastern Athabasca Basin region. The company's strategic expansion now encompasses key geochemical and geophysical anomalies indicative of potential uranium mineralization, contributing to a notable gain in its stock value.

Project Expansion Details and Geophysical Findings

Cosa Resources reported the expansion of its wholly-owned Orbit Project to cover a larger area of over 15,000 hectares. This expansion strategically targets coincident radon, helium, and hydrogen anomalies, along with electromagnetic (EM) conductors. These "pathfinder" gases and conductive features are recognized indicators in uranium exploration, often signaling underlying uranium deposits.

Remote sensing work was instrumental in identifying two primary target areas: ORS-1 and ORS-2. ORS-1, located in the northern sector of Orbit, spans approximately 1,000 by 1,000 meters. ORS-2, situated within newly staked lands, measures roughly 750 by 600 meters and adds an estimated 3 kilometers of drill-ready conductive strike length. The project benefits from its location 21 kilometers south of Cameco's Key Lake Mill, offering advantageous proximity to essential infrastructure, including highways, powerlines, and permanent camp facilities. Critically, the Orbit project areas are described as having no sandstone cover, which Andy Carmichael, VP of Exploration for Cosa, noted as beneficial:

"With no sandstone to inhibit the migration of pathfinder gases, we view remote sensing as having great potential to aid exploration at Orbit. Remote sensing identified two zones of coincident anomalous radon, helium, and hydrogen, including one zone later covered by targeted staking. Recent staking also added 3 kilometres of drill ready conductive strike length. We're pleased to have bolstered the target inventory of a Project located near highways, powerlines, permanent camp facilities, and the Key Lake uranium mill. Planning is underway for follow up in 2026."

Market Reaction and Investor Optimism

The announcement of the Orbit Project expansion and the identification of significant pathfinder anomalies spurred a positive market response for Cosa Resources. Shares of COSA.V on the TSX Venture Exchange rose by 7.84% on the news, reflecting increased investor confidence. This advance indicates that the market perceives the exploration update as a significant de-risking event for the Orbit Project, enhancing its prospectivity for future uranium discoveries. The presence of drill-ready targets and a clear exploration strategy appear to have resonated with investors looking for early-stage success in the Uranium Sector.

Broader Context within the Athabasca Basin

The Athabasca Basin in Saskatchewan is globally renowned for its high-grade uranium deposits, making exploration successes within the region particularly noteworthy. Cosa Resources operates a portfolio spanning approximately 237,000 hectares across multiple 100% owned and Joint Venture projects within or adjacent to established uranium corridors in this basin.

The company's strategic collaboration with Denison Mines, a major player in the uranium industry and Cosa's largest shareholder, provides further context. This partnership grants Cosa access to additional prospective uranium exploration projects in the eastern Athabasca. Furthermore, Cosa's ongoing 2025 drilling program at the Murphy Lake North Joint Venture (70/30 with Denison) has already identified promising geological structures and alteration zones, suggesting continued exploration momentum across its assets. The recent positive results from the Orbit Project add another layer of exploration success to the company's growing portfolio within this key uranium-producing region.

Outlook and Future Exploration Efforts

Looking ahead, Cosa Resources is planning follow-up work for 2026 at the expanded Orbit Project, leveraging the identified geochemical and geophysical targets. The focus will be on advancing these drill-ready areas. Concurrently, the company also anticipates further follow-up exploration and drilling at the Murphy Lake North Joint Venture in 2026, building upon the structural and alteration intercepts encountered in 2025. These planned activities underscore Cosa's commitment to methodically exploring its properties within the highly prospective Athabasca Basin, with the potential for additional news flow to influence future market performance.
