Purecore Metals signs LOI for up to 100% of Yurchison uranium property

The proposed option deal with Skyharbour Resources covers 22 claims totaling about 35,028.93 hectares in Saskatchewan's Athabasca Basin and remains subject to due diligence, a definitive agreement and approvals.

Summary

Purecore Metals Inc. has signed a non-binding letter of intent dated July 15, 2026 with Skyharbour Resources Ltd. to acquire an option to earn up to a 100% interest in the Yurchison uranium property in the Wollaston Domain of the Athabasca Basin in northern Saskatchewan. The property consists of 22 claims covering about 35,028.93 hectares and lies roughly 75 km south of Cameco's Rabbit Lake operation, with Highway 905 crossing the claims. Historical exploration included airborne electromagnetic, magnetic and radiometric surveys, ground geophysics, mapping, geochemical sampling and drilling, with uranium values of 0.09% to 0.30% U3O8 and molybdenum values of 2,500 ppm to 6,400 ppm reported near old trenches. The companies said most work was completed before 2000, with limited follow-up since, while newer airborne EM, magnetic and radiometric surveys were flown in 2022 and 2023. The proposed transaction remains subject to Purecore's due diligence, a binding definitive agreement, board approvals and regulatory clearance including Canadian Securities Exchange approval.

Terms & Concepts
  • U3O8: Triuranium octoxide, the standard industry form used to report uranium assay grades and resources.
  • SEDEX-style Pb-Zn mineralization: Sedimentary exhalative lead-zinc mineralization, a deposit type formed when metal-rich fluids precipitate in sedimentary basins.
  • airborne electromagnetic survey: A geophysical method flown from the air to detect conductive subsurface features that can help identify mineralization targets.
