Skyharbour Resources Ltd. (TSXV: SYH) (OTCQX: SYHBF) (Frankfurt: SC1P) has sold Cosa Resources Corp (TSXV: COSA) (OTCQB: COSAF) (FSE: SSKU) two mineral claims on its Karin Property, located approximately 22 kilometers south of the Key Lake Mill.
The company explained on Monday that property purchase and sale agreement is for 250,000 Cosa shares. Skyharbour originally picked these claims up through low-cost online staking. At present, Skyharbour still holds five other claims in the new Karin Project, which is over 19,116 hectares.
The original Karin Project included 7 claims, covering 25,165 hectares in the Highrock Lake area. The area is prospective for both unconformity-related and pegmatite-hosted uranium mineralization.
Explorers conducted various activities at the Karin project from the late 1960s to the early 1980s. These activities included airborne EM, magnetics and radiometrics, radon surveys, prospecting, geological mapping, lake water and sediment sampling, and limited diamond drilling.
Explorers drilled five holes at the Karin project, intersecting significant rock types like Wollaston Supergroup meta-arkose, semipelitic to pelitic gneisses, amphibolite, and pegmatite to granodiorite. These rocks are important because they can host uranium deposits. They also observed localized hematite, chlorite, epidote, and goethite alteration, which can indicate mineralization processes.
The drilling targeted strong EM conductors and radon anomalies, but the company did not follow up on several historical EM anomalies. Since this work occurred before modern geophysics and uranium exploration models, additional prospective targets likely remain untested.
Since the 1980s, the Karin project has been largely unexplored and remains prospective for both intrusive-type and unconformity-related uranium deposits, as well as intrusive-related rare earth elements.

The Karin Project is surrounded by exploration and mining activities
Denison Mines Corp. (TSX: DML) (NYSE: DNN) actively explores the region with projects like Wheeler River, a major undeveloped uranium project.
Furthermore, Cameco Corporation (NYSE: CCO) (TSX: CCJ) operates several prominent uranium resources nearby, including the McArthur River and Cigar Lake mines, some of the world’s largest and highest-grade uranium properties.
NexGen Energy Ltd (TSX: NXE) (NYSE: NXE) (ASX: NXG) focuses on its Rook I project, featuring the Arrow deposit, one of the most promising undeveloped uranium projects globally. Meanwhile, ATHA Energy Corp.‘s (TSXV: SASK) (FRA: X5U) (OTCQB: SASKF) Gemini Project is located 31 kilometers northeast of Cameco’s Key Lake Mine in the Athabasca Basin.
However, ATHA’s latest developments are further north than the Athabasca Basin.
ATHA Energy Corp. discovered promising radiation in six drill holes during its first exploration program at the Angilak Project in Nunavut. The program’s first phase involves 10,000 meters of drilling, targeting high-grade uranium mostly outside the historic Lac 50 deposit.
The initial six holes totaled 2,817.6 meters and focused on the Main Zone, Eastern Extension, and J4 and Ray Zones. The Angilak Project, located in the Angikuni Basin, hosts the Lac 50 Uranium Deposit with a historical estimate of 43.3M lbs at 0.69 per cent U3O8. The 2024 program includes drilling, airborne surveys, and sampling.
