Cosa Announces Commencement of Ground Geophysics and Access Trail Establishment at the 100% Owned Ursa Uranium Project

Highlights

• 80 km of ground-based electromagnetic (EM) surveying to be completed over five target areas

• Results will aid targeting for initial drill campaign planned for Q1 2024

• Best-in-class EM technology and modelling techniques, a significant advantage over the technological limitations of the historical work at Ursa

Keith Bodnarchuk, President & CEO, commented: "This survey marks the start of Cosa's ground-based exploration at Ursa, a significant milestone for the Company and the final step before initiating diamond drilling. We are pleased to have quickly advanced the Project to this stage and look forward to updating the market on the survey results. With an abundance of target areas at Ursa and several target generation programmes planned across our portfolio, 2024 will be a busy and exciting year for Cosa."

Andy Carmichael, VP of Exploration commented: "Since receiving the MobileMT™ airborne survey and 3D inversion results in 2023, we have been eager to launch ground-based follow-up surveying. The survey contractor Cosa selected for this work has extensive experience in the Athabasca Basin and has deployed cutting edge EM survey equipment to Ursa. We look forward to receiving the ground EM survey results and continuing to plan for the upcoming winter drill program. With the onset of frozen ground conditions in northern Saskatchewan, Cosa has also begun establishing a winter trail to access the Project ahead of drill mobilization."

Electromagnetic Surveying

The ground EM surveys are being completed to follow-up the property wide MobileMT™ airborne survey results announced on November 1^st, 2023. From the airborne survey Cosa has identified 11 target areas which contain conductivity anomalies consistent with the unconformity-related uranium deposit model (Figures 2 and 3). Top priority target areas are structurally complex basement conductive trends coincident with sandstone-hosted, kilometre-scale zones of anomalous conductivity, which could reflect large-scale hydrothermal alteration zones commonly associated with Athabasca uranium deposits.

Cosa has engaged Discovery International Geophysics (Discovery) of Saskatoon, SK, to complete at least 80 kilometres of ground EM surveying to upgrade the accuracy of conductor locations in advance of diamond drilling. Discovery has deployed a survey system featuring state of the art superconducting quantum interference device (SQUID) EM receivers to collect the best quality data possible and maximize the signal to noise ratio. In conjunction with the stepwise moving loop transient electromagnetic (SWML-TEM) survey technique, the SQUID receivers significantly increase data resolution compared to historical EM surveys completed on the Project.

"Forward-looking information" includes, but is not limited to, statements with respect to the activities, events or developments that the Company expects or anticipates will or may occur in the future, including, without limitation, planned exploration activities. Generally, but not always, forward-looking information and statements can be identified by the use of words such as "plans", "expects", "is expected", "budget", "scheduled", "estimates", "forecasts", "intends", "anticipates", or "believes" or the negative connotation thereof or variations of such words and phrases or state that certain actions, events or results "may", "could", "would", "might" or "will be taken", "occur" or "be achieved" or the negative connotation thereof. Forward-looking statements in this news release include, among others, statements relating to: the exploration, development, and production at the Company's mineral projects.

Forward‐looking statements and forward‐looking information relating to any future mineral production, liquidity, enhanced value and capital markets profile of the Company, future growth potential for the Company and its business, and future exploration plans are based on management's reasonable assumptions, estimates, expectations, analyses and opinions, which are based on management's experience and perception of trends, current conditions and expected developments, and other factors that management believes are relevant and reasonable in the circumstances, but which may prove to be incorrect. Assumptions have been made regarding, among other things, the price of uranium and other commodities; no escalation in the severity of public health crises; costs of exploration and development; the estimated costs of development of exploration projects; the Company's ability to operate in a safe and effective manner and its ability to obtain financing on reasonable terms.
