The first follow-up drilling program was completed in the winter (January to March). The program was very successful with 11 of 12 drill holes intersecting significant uranium mineralization.
Highlights include:
- LE19-02: 3.5m @ 10.4% U3O8,
- LE19-03: 3.0m @ 2.7% U3O8, 2.3% Ni,
- LE19-06: 4.0m @ 3.8% U3O8,
- LE19-09: 4.5m @ 4.2% U3O8, 1.1% Ni, 0.8% Co
- LE19-12: 8.5m @ 3.2% U3O8 and 2.1% Ni
Following the winter drilling campaign, the Hurricane zone was open for expansion on most sections, along-strike in both directions, and measured 150 metres long, 40 metres across and up to 10 metres thick.
Drilling resumed in the summer of 2019 with a 17-drill hole campaign designed primarily to evaluate the potential for expansion along-strike to the east of the winter drilling. This program was also successful, with the best intersection to date being obtained from drill hole LE19-16A (7.0m @ 5.4% U3O8, 0.7% Ni and 0.1% Co). Drill holes LE19-18 (3.0m @ 1.5% U3O8) and LE19-18C1 (5.0m @ 1.2% U3O8) successfully extended high-grade uranium mineralization 100 metres to the east.
This was followed by a large, 250m further step-out to the historical drill hole KER-07 section. Weak uranium mineralization in drill hole LE19-22 successfully extended the Hurricane zone footprint to 500 metres long. A 40-metre gap on-section between drill holes LE19-22 and KER-07 may contain significant uranium mineralization. The next large step-out section 200m along-strike to the east was begun with drill hole LE19-26. Intended to be a stratigraphic drill hole angled beneath the Hurricane zone target area, LE19-26 encountered a thick zone of sandstone alteration and structure characterized by elevated trace element geochemistry and radioactivity. All of this occurs well north of the expected trace of the Hurricane zone. The drill hole is located on the western edge of a prominent basement DC-resistivity low anomaly that extends to the east for several kilometres, likely indicating the presence of highly graphitic basement rocks – the preferred host for uranium deposits in the Athabasca basin.
