The Higher Grade A2 Sub-Zone Returns Intense Radioactivity and Strike Length of Arrow Zone Extended to 670m

NexGen Energy Ltd. (TSXV:NXE, OTCQX:NXGEF) announced results from five angled holes from our on-going 30,000 m winter 2016 drilling program on our 100% owned Rook I Property in the Athabasca Basin, Saskatchewan.
Highlights include:

A2 Shear:

• AR-16-63c3 (18 m down-dip and southwest from AR-16-62) intersected 147.0 m of total composite mineralization including25.6 m of total composite off-scale radioactivity (10,000 – >61,000 cps) within a 197.5 m section (444.0 to 641.5 m) in the Sub-Zone.
• AR-16-64c3 (20 m northeast of AR-15-44b) intersected 102.0 m of total composite mineralization including 21.25 m of total composite off-scale radioactivity (10,000 – >61,000 cps) within a 149.0 m section (465.0 to 614.0 m) in the Sub-Zone.

A3 Shear:

• AR-16-59c6 (48 m down-dip and southwest of AR-15-61c2) intersected 28.15 m of total composite mineralization including2.85 m of total composite off-scale radioactivity (>10,000 to 54,000 cps) within a 64.0 m section (768.0 to 832.0 m) in the A3 shear.

• AR-16-71 (58 m down-dip and southwest of AR-15-52) intersected 31.5 m of total composite mineralization including 0.8 m of total composite off-scale radioactivity (>10,000 to 25,000 cps) within a 113.0 m section (582.0 to 695.0 m) in the A3 shear.

Garrett Ainsworth, Vice-President, Exploration and Development, commented:

Drill holes AR-16-63c3 and -64c3 have significantly grown the higher grade A2 sub-zone with consistent high grade mineralization over wide intervals.  Further testing within the A2 and A3 shears continues to show strong continuity through infill drilling, and substantial expansion from step out drilling.
