Cosa Resources Announces Commencement of Ground Geophysics and Expansion of Its Uranium Exploration Technical Team

In This Article:

Vancouver, British Columbia--(Newsfile Corp. - May 16, 2024) - Cosa Resources Corp. (TSXV: COSA) (OTCQB: COSAF) (FSE: SSKU) ("Cosa" or the "Company") is pleased to announce the commencement of Ambient Noise Tomography (ANT) surveying at the 100% owned Ursa and Orion Uranium Projects in the Athabasca Basin and the appointment of Daniel Hrabok as Senior Project Geologist.

Mr. Hrabok is a Professional Geoscientist with over a decade of experience exploring for uranium. Having joined Areva (now Orano) in January of 2013, Mr. Hrabok has extensive experience in uranium exploration and at post-discovery projects throughout the Athabasca and Thelon Basins. Mr. Hrabok has been part of teams working on notable uranium properties including Shea Creek, McClean Lake, Maybelle River and the Kiggavik projects and is familiar with a broad range of uranium mineralization settings and styles. He has also been part of teams on the Parker Lake and Close Lake projects, which are adjacent to Cosa's Ursa, Astro, and Orion projects.

Andy Carmichael, VP of Exploration, commented: "Mr. Hrabok's level of experience, encompassing more than a dozen uranium projects of varied maturity and geological setting, brings a wealth of technical and operational expertise to Cosa's exploration team. We are well positioned to leverage Dan's experience operating projects throughout the Athabasca Basin to identify and pursue future opportunities, while more effectively advancing our existing portfolio of uranium projects. Passionate and capable exploration Geologists are a fundamental component of a successful exploration team, and we are proud to include Dan in our endeavor to discover the Athabasca Basin's next tier-1 uranium deposit."

Daniel Hrabok, Senior Project Geologist, commented: "I am thrilled to be joining Cosa Resources and to be part of an experienced and accomplished technical team. In a relatively short time, the Cosa team has acquired and is quickly advancing a portfolio of prospective and under-explored uranium projects. Results from the recently completed inaugural drill program at Ursa are encouraging, and I am excited to apply my experience to our projects across the Athabasca Basin and continue Cosa's hunt for the next major uranium discovery."

Ambient Noise Tomography Survey

ANT surveying has commenced and will be completed at both the Ursa and Orion Projects over the coming weeks. At Ursa (Figure 1), ANT will be deployed over roughly 27-kilometres of conductive strike length. Most notably, included in the survey area is winter drill hole UR24-03 which intersected encouraging structure and hydrothermal alteration (dravite-rich breccias) several hundred metres above the sub-Athabasca unconformity. At Orion (Figure 2), ANT will cover a kilometre-scale zone of sandstone hosted conductivity anomaly that is coincident with potentially complex conductive basement geology on strike with weak mineralization and encouraging structure and hydrothermal alteration intersected at Orano's neighbouring Parker Lake project. ANT has been demonstrated to be a cost-effective and low-impact method of locating hydrothermal alteration systems at depth, and results of this work will be used to guide future drilling, including the upcoming summer drill program at Ursa. Geochemistry and clay spectroscopy results for the recently completed winter drill program at Ursa are still pending and will be incorporated into the Company's drill strategy upon receipt.
