URANIUM: NexGen moves Arrow closer to development

SASKATCHEWAN – Vancouver-based NexGen Energy now has results from latest batch of 29 holes it drilled at the Rook I uranium property in the Athabasca Basin. The program set out to characterize areas within the Arrow deposit’s footwall, lateral development, potential underground infrastructure locations. The information will be incorporated in the prefeasibility study released earlier this month.

Three shaft pilot holes were completed to a depth of between 650 and 702 metres. The holes were drilled with a 3-metre radius. They intersected minimal structure and showed low hydraulic conductivity throughout via packer testing at regular intervals.

NexGen also drilled an under-explored area northeast of the current A2 high grade zone. Drilling identified mineralization between the A2 and A3 shears as well as revealing the continuity of high grade mineralization beyond the currently defined A2 high grade domains. One of the holes intersected 55.5 metres of total composite mineralization including 2.25 metres of off-scale radioactivity within a 109.5-metre section in the A2 shear.

The next step will be to begin a two-stage, 120,000-metre high density drilling program to begin  in mid-December 2018.

Recent exploration drilling results are available in the Nov. 22, 2018, news release posted at Additionally, the results of the Rook I preliminary feasibility study are available in the corporate presentation.
