The angled drill hole AR-15-44b, which is located 76m along strike to the southwest from vertical drill hole AR-14-30, has been highlighted in the published report.

The hole has been expanded considerably to intersect some of the strongest off-scale (>10,000 to >61,000 cps) radioactivity at Arrow to date connected chiefly with dense accumulations of semi-massive to massive pitchblende mineralization.

NexGen exploration and development vice-president said: "Angled drill hole AR-15-44b has taken the Arrow zone to the next level with almost three times more >61,000 cps total composite off-scale radioactivity than in vertical hole AR-14-30, which is located 76 m along strike to the northeast within the A2 shear.

"Arrow now has significant off-scale mineralization at both the southwest and northeast extents, which we will aggressively follow up on in our summer drill program.

"Other mineralized intersections from AR-15-42a and -43a continue to confirm continuity, and increase the extents within the high grade cores of the A2 and A3 shears."

NexGen chief executive officer Leigh Curyer said: "AR-15-44b is clearly another significant result in expanding Arrow. The drilling methodology of bold step outs keeps delivering outstanding results and the Company is confident of being in a position to deliver an initial resource estimate prior to the end of 2015."
