Primary Minerals
Uranium
A program of 10,325m of core drilling in 24 drill holes was completed in March with two drills. One drill rig concentrated on the western end of the Hurricane zone footprint, expanding the mineralization west to the property boundary. A second drill rig began evaluating the potential for additional uranium mineralization well to the east (200m to 1,600m) of the Hurricane zone footprint. Both of these efforts were successful.
Western Hurricane Zone Expansion
All 14 drill holes completed were mineralized. Further, a new zone characterized by very high-grade mineralization over thick intervals was intersected in several drill holes. The best example is drill hole LE20-34, which intersected 33.9% U3O8 over 8.5m, including 57.1% U3O8 over 5.0m. All five of the westernmost sections remained open for expansion to the north and/or to the south.
Eastern Potential
Drilling to the east of the Hurricane zone evaluated the western portion of a 5km long basement conductive zone mapped by the 2019 DC-resistivity survey. Strongly graphitic basement gneisses hosting brittle faults were intersected in all the widely spaced reconnaissance drill holes completed up to 1.6km east of the Hurricane zone during the winter program. Several of these drill holes also intersected significant sandstone alteration with elevated sandstone uranium geochemistry and/or illitic clay alteration.
A program of 9,578 metres in 24 drill holes was completed in October 2020, with many outstanding intersections obtained as the footprint expanded, including:
- LE20-76: 7.5m @ 38.8% U308, including 3.5m @ 74.0% U3O8
- LE20-72: 6.0m @ 6.2% U308, including 1.5m @ 20.7% U3O8
- LE20-68: 11.0m @ 6.9% U308, including 1.5m @ 49.3% U3O8
- LE20-64: 5.0m @ 48.8% U308 including 4.0m @ 57.5% U3O8
- LE20-62: 4.5m @ 6.2% U308 including 2.5m @ 11.1% U3O8
- LE20-57: 10.0m @ 11.7% U308 including 2.5m @ 46.0% U3O8
- LE20-54: 9.0m @ 12.8% U308 including 4.0m @ 27.1% U3O8
