NexGen Confirms Strong Uranium Mineralization to the Northwest of the A1 Shear and Outside the A3 High Grade Domain
Jan 17, 2018, 06:30 ET
VANCOUVER, Jan. 17, 2018 /CNW/ - NexGen Energy Ltd. ("NexGen" or the "Company") (TSX:NXE, NYSE MKT:NXE) is pleased to report assay results for the final 28 holes from our summer 2018 drill program on our 100% owned, Rook I property, in the Athabasca Basin, Saskatchewan.
Arrow Step-out Drilling
New high grade mineralization was discovered and confirmed for the first time, northwest of the A1 shear with a geotechnical test hole and will be followed up during the winter 2018 drill program. Additionally, step-out drilling outside of the area of the current Mineral Resource estimate has resulted in the most heavily mineralized hole in the A3 shear to date. In addition,
Northwest of the A1 Shear
- Geotechnical hole GAR-17-001 intersected 8.0 m at 1.43% U3O8 (531.5 to 539.5 m), including 4.5 m at 2.51% (531.5 to 536.0 m) in a new mineralized area northwest of the A1 shear.
A3 Step-Outs
- AR-17-159c1 intersected 26.5 m at 10.60% U3O8 (427.5 to 454.0 m) including 13.0 m at 20.74% U3O8 (439.0 to 452.0 m) located 25 m outside of the area of the current Mineral Resource estimate in the A3 High Grade Domain. This represents the best hole drilled in the A3 shear to date.
- AR-17-159c2 intersected 49.0 m at 2.30% U3O8 (429.5 to 478.5 m) including 5.0 m at 11.72% U3O8 (463.0 to 468.0 m) and 2.0 m at 9.88% U3O8 (451.0 to 453.0 m) in the High Grade Domains of the A3 Shear located 15 m outside of the area of the current Mineral Resource estimate.
- AR-17-167c1 intersected 15.0 m at 1.49% U3O8 (481.5 to 496.5 m) including 2.0 m at 10.56% U3O8 (489.0 to 491.0 m) in the A3 Shear located 45 m outside of the Mineral Resource.
Southwest Gap Step-Outs
- AR-17-161c1 intersected 9.5 m at 2.31% U3O8 (827.0 to 836.5 m), including 2.0 m at 10.57% U3O8 (833.5 to 835.5 m) in the A3 Shear of the Southwest Gap.
Arrow Infill Drilling
Infill drilling has continued to confirm the strong continuity of mineralization at the Arrow deposit. The A3 high-grade domains have now been largely drilled at a spacing of 25 m x 25 m. Key potential expansion areas have been identified surrounding these domains and will be followed-up during the winter 2018 drilling program.
A2 & A3 Infill
- AR-17-176c2 intersected 17.54 m at 3.51 % U3O8 (649.5 to 667.04 m), including 4.0 m at 12.88% U3O8 (659.0 to 663.0 m) and 15.5 m at 0.77% U3O8 (692.0 to 707.5 m), including 1.5 m at 7.71% U3O8 (693.5 to 695.0 m) in the A2 Shear.
- AR-17-164c2 intersected 21.5 m at 1.80% U3O8 (588.0 to 609.5 m), including 3.0 m at 12.14% U3O8 (590.5 to 593.5 m) in the A3 Shear.
- AR-17-155c3 intersected 7.0 m at 2.68% U3O8 (619.0 to 626.0 m), including 2.5 m at 7.21% U3O8 (619.0 to 621.5 m) in the A3 Shear.
Development, Activities & Financial
- Pre-feasibility technical studies including geotechnical work, hydrogeological work and metallurgy continue in advance of a maiden Pre-Feasibility Study scheduled to be published in Q3/2018.
- Planning for the winter 2108 drilling program is complete and will begin imminently.
- The Company has cash on hand of approximately $155 million.
Garrett Ainsworth, Vice-President, Exploration and Development, commented: "The final assays from our summer 2017 drill program confirm high grade mineralization in key areas for resource growth. We have been especially pleased with results from the A3 High-Grade Domains with hole -159c1 returning the best intercept in the A3 shear to date. Furthermore, hole GAR-17-001 which was a geotechnical hole designed to test the ground conditions of the Arrow Deposit also hit mineralization adjacent to the northwest of the A1 shear indicating the potential of an entire new mineralized shear zone."
Leigh Curyer, Chief Executive Officer, commented: "Discovery of a potential A0 shear highlights the incredible prospectivity that continues to exist at the Arrow Deposit. NexGen's Rook 1 project hosts 9 kms of the prolific Patterson Corridor bordering the edge of the Athabasca Basin and significant drilling is planned in order to determine the full extent of mineralization at Arrow, and along strike. Further, strong mineralized intercepts within, and around, the A3 High Grade Domain continue to demonstrate the strong continuity of mineralization at Arrow as we progress to pre-feasibility."
