Key Lake Road Projects
Grey Island
key highlights
Highly prospective
The Grey Island Property is situated 35 km east of the Cable Bay Shear Zone (CBSZ), a significant northeast-trending basement structural feature. This property is notably intersected by crosscutting structures emanating from the CBSZ, meeting a northeast-trending structure within its boundaries.
significant findings
The property is characterized by strong electromagnetic conductors, explored minimally by only one drill hole to date. This drilling revealed significant findings, including strong bleaching and alteration in the sandstone over an 86m section, as well as the intersection of pyritic and strongly graphitic basement rocks beneath the unconformity.
potential discoveries
The average depth of the unconformity at the Grey Island Property is around 270 meters from the surface, indicating the potential for further significant geological discoveries within the property’s depths.
Background
The project consists of 22 mineral claims totaling 47,912 ha in the southeast area of the Athabasca Basin, and is 100% owned by F3 Uranium Corp. It is located 70km northwest of the Key Lake mill and approximately 15km inside the southern margin of the Athabasca Basin, where the depth to the unconformity averages ~270m. The property is located halfway between the Key Lake Mine and Cameco’s Centennial uranium deposit.
Since the 1960s, the Grey Island area has been targeted for its promising geology, including significant work by the Saskatchewan Mining Development Corp (SMDC) in the 1980s. The property features key geological indicators of high-grade Athabasca Basin deposits: basement electromagnetic (EM) conductors within magnetic low corridors and adjacent magnetic highs. A notable eight-kilometer ground EM conductor in the east was explored by a single drill hole, revealing altered sandstone and pyritic, graphitic rock beneath the unconformity, with localized high graphite content and elevated uranium levels. The west and northernmost claims of the property contain long, untested conductor complexes within magnetic lows, highlighting the region’s exploration potential, despite previous unsuccessful drilling attempts in 2008.
