NexGen Energy has found extensive mineralisation after eight drill holes were intersected during the drilling programme at its Arrow prospect in Athabasca Basin, Saskatchewan.
Off-scale radioactivity has been intersected in each of the A1, A2, A3 and A4 shears
In the A1 shear, the high-grade mineralised interval from hole AR-16-84c1 has been confirmed and drilling has been expanded with two further holes.
This was highlighted by hole AR-16-84c3, which was drilled 33m down and intersected 35.5m of total composite mineralisation, including 2.6m of total composite off-scale mineralisation.
The new area of high-grade mineralisation in the A1 shear is not part of the initial Arrow deposit resource estimate.
This estimate only includes drilling up to last October.
In the A2 shear, drilling has also continued to confirm strong mineralisation.
Drill holes AR-16-80c4, -81c3, and -86c1 all intersected more than 10m of total composite off-scale mineralisation, and therefore has a significant potential for expansion of the A2 high grade domain around each of these holes.
Hole AR-16-86c1 indicated the largest total composite mineralisation till date across the A2 to A4 shears.
This hole was drilled at the currently defined southwest extent of the sub-zone, intersecting 92m of total composite mineralisation in the A3 shear, and 246m of total composite mineralisation throughout the complete hole.
Under the A4 shear, 3.6 m of off-scale radioactivity has been intersected in drill hole AR-16-86c1.
This is a 19m down-dip from hole AR-16-76c1.
NexGen Energy vice-president for exploration and development Garrett Ainsworth said: "These latest drill results of infill drilling continue to rapidly expand the size and scale of Arrow.
"Drill hole AR-16-86c1 has returned the highest total composite mineralisation to date, which demonstrates the strength and width extent of the mineralising system responsible for precipitating the Arrow deposit."
NexGen Energy CEO Leigh Curyer said: "There are 27 assays pending from the winter programme which includes 6 assays from the sub-zone and we are still actively drilling with 3 rigs.
"In total 42 holes have been drilled at Arrow since the resource estimate and we plan to more than double that number by year-end.
"Planning for an expanded summer 2016 drill programme is in process which will include infill and expansion drilling around Arrow, the 180m southwest extension, Cannon and regional targets along trend from Arrow."
