URANIUM: NexGen expands high grade zone at Arrow deposit

SASKATCHEWAN – Vancouver-based NexGen Energy has drilled 37.4 metres of off-scale radioactivity, thus expanding the Arrow deposit high grade A2 domain at its Rook I uranium project in the Athabasca Basin.

Hole AR-16-17c4 intersected a dense accumulation of massive pitchblende that measured 37.4 metres of off-scale radioactivity, including a 5.5 metre section measuring >61,000 cps, of which 4.6 metres was continuous. This is one of the best holes every drilled at the Arrow deposit, said NexGen.

The A2 high grade domain has 43-101 compliant resources of inferred material containing 120.5 million lb of uranium oxide contained in 41,000 tonnes grading 13.26% U3O8. That resource is contained within the Arrow deposit that has an inferred resource of 201.9 million lbs of uranium oxide in 3.48 million tonnes grading 2.64% U3O8.

Using an Rs-125 spectrometer scintillometer, NexGen has confirmed anomalous uranium radioactivity 1.3 km northeast of the Arrow deposit. The new area, dubbed Cannon,  is coincident with a gravity and weakened VTEM conductor, says the company. All 11 holes drilled at Cannon intersected strong to intense hydrothermal alteration, and four of them returned anomalous radioactivity counts.

A week earlier NexGen reported drilling the strongest uranium intercept so far in the A1 shear zone. Hole AR-16-84c1 cut 55.0 metres of total composite mineralization including 8.35 metres that measured between 10,000 and 48,000 cps, the strongest reading ever within the A1 shear zone.
