IsoEnergy Ltd. has begun a program of core drilling targeting basement-hosted mineralization at its Geiger uranium property in the Eastern Athabasca Basin of Saskatchewan.
The Geiger property is located 13 kilometres northwest of IsoEnergy’s Radio property near several uranium deposits, mines and mills. The Roughrider and Midwest deposits are both within 20 kilometres of the property, as is AREVA’S McClean Lake uranium mine and mill.
Geiger is adjacent to the Wollaston-Mudjatik transition zone, a major crustal-scale structural zone related to most of the major uranium deposits in the eastern Athabasca Basin. Sandstone cover at the property is thin and ranges between 101 and 358 metres. High grade basement hosted uranium mineralization is present on the property and it is the focus of IsoEnergy’s exploration efforts.
Drill hole HL-50 intersected 2.74 per cent U3O8 over 1.2 metres in the basement on the H11 South conductor. Follow-up efforts were focused primarily on locating mineralization at the sub-Athabasca unconformity. Consequently, opportunities for additional basement hosted mineralization proximal to HL-50 are considered excellent.
Additionally, drill hole HL-76 was completed 1.6 kilometres along strike to the northeast along the same conductor as HL-50 and intersected 0.65 per cent U3O8 over 0.1 metres. Mineralization in HL-76 is located in the basement and is part of a broader 27 meter thick zone of strong alteration and elevated geochemistry.
A program of 2,800 metres of core drilling is planned in eight drill holes. There are two target areas which surround the mineralization observed in drill holes HL-50 and HL-76, described above. The objective of the program is to evaluate both areas for extensions of previously drilled, basement hosted mineralization.
The results will be used to determine the orientation and morphology of the mineralization and alteration, allowing the company’s technical team to vector into the core of the systems.
Drilling operations are expected to be complete by the end of February.
