NexGen Energy (TSX:NXE) reported assay results for 8 holes from its most recent winter drill program at the Rook property. In addition to high-grade uranium intersections, the company also reported high grade gold and silver values in the A2 shear.
As quoted in the press release:
A2 Sub-Zone
Extensive and continuous high grade uranium mineralization in the higher grade A2 sub-zone (the “Sub-Zone) is confirmed with 2 assay results reported herein.
- AR-16-81c3 (127 m up-dip and southwest from AR-15-44b) intersected 23.0 m at 17.19% U3O8 including 9.5 m at 39.82% U3O8and 5.0 m at 49.27% U3O8.
- AR-16-86c1 (84 m up-dip and southwest from AR-15-44b) intersected 44.5 m at 8.85% U3O8 including 19.0 m at 20.40% U3O8and 5.0 m at 39.52% U3O8.
A2 Shear High Grade Domain
- AR-16-80c4 (110 m up-dip and southwest from AR-15-44b) intersected 25.0 m at 6.38% U3O8 including 10.0 m at 14.66% U3O8.
- AR-16-84c2 (33 m up-dip and northeast from AR-15-44b) intersected 39.0 m at 2.10% U3O8 including 18.5 m at 4.27% U3O8.
- AR-16-84c3 (34 m up-dip and northeast from AR-15-44b) intersected 31.0 m at 3.26% U3O8 including 18.0 m at 5.58% U3O8and 6.5 m at 10.89% U3O8.
- AR-16-85c1 (90 m up-dip and southwest from AR-15-44b) intersected 24.0 m at 4.40% U3O8 including 3.5 m at 29.15% U3O8.
Substantial mineralization was intersected completely outside the current boundary of the A2 high grade domain in six holes (Figure 1). There is significant potential for continued expansion and this will be a focus of the 35,000 m summer drilling program.
High Grade Gold
High grade assays intersected in the A2 shear also contain high grade gold and silver values, with individual 0.5 m samples ranging from below detection limits up to 90.4 g/t Au and 418 g/t Ag (Table 1). Hole AR-16-81c3 returned 9.5 m at 7.9 g/t Au and AR-16-86c1 returned 20.4 m at 1.9 g/t Au. Also of significant importance, geochemical analyses continue to show very low concentrations of deleterious elements (arsenic, antimony, selenium), which is a favourable characteristic for processing of uranium ores in the Athabasca Basin.
A three-dimensional view of the A2 High Grade Domain, a plan map, and the A2 long section are shown in Figures 1 to 3.
