NexGen Energy has revealed assay results of the six angled holes from the expanded summer 2015 drilling program on its Rook I property of Athabasca Basin, Saskatchewan.
The hole AR-15-49c2 has delivered significant continuous high-grade uranium mineralization in the A2 shear similar to that found in the hole AR-15-44b.
The firm has also discovered broad and extensive uranium mineralization in both the A2 and A3 shears.
AR-15-49c2 is said to have returned 50.0m at 12.01% U3O8, including 18.0m at U3O8 and 4.5m at 40.64% U3O8 at 40.64% U3O8.
The highest grade assay result has been observed at the Arrow zone at 76% U3O8 over 0.50m. The zone covers an area of 645m through 215m with a vertical extent of mineralization commencing from 100 to 920 m, and remains open in all directions and at depth.
AR-15-48c1 has returned 60m at 0.91% U3O8, including 12.5 m at 3.09% U3O8 in the A2 shear and 24m at 5.43% U3O8, comprising 10.5 m at 10.12% U3O8 in the A3 shear.
NexGen Energy CEO Leigh Curyer said: "AR-15-49c2 is another world class hole at the Arrow zone. Our large step outs continue to deliver amazing results on any metric for a uranium discovery in the Athabasca Basin.
"This has all been accomplished in comparatively very few holes and low cost for a discovery of this nature and it’s a credit to the entire team."
