In addition, the Rook I camp has undergone significant improvements leading into this year’s program to facilitate an increase in the number of rigs, improve logistical support and the continued optimization of operations.

The winter 2016 drill program will comprise of 30,000 m of drilling and an increase to six diamond drill rigs making it the most number of rigs ever operated at Arrow. The Company has cash on hand of approximately $34M as at January 1, 2016.

There are three primary objectives of the winter 2016 drill program budgeted at $12M;

Core drilling at Arrow Zone;
Delineating the higher grade A2 sub-zone (the "Sub-Zone"),
Drill testing extensions of the A2 and A3 high-grade shears further southwest,
Testing for flat lying mineralization at the basement unconformity further northeast.
Step-out drilling along strike from the Arrow zone along the 9 km Patterson corridor on Rook I.
Drill the Bow discovery.

NexGen Energy CEO Leigh Curyer said: "Given the successful 2015 results at Arrow, it has clearly justified expanding the drilling program and improving camp infrastructure at Rook I to support the continued optimization of the project. The addition of a sixth rig makes this winter’s program the largest ever at Arrow. Moreover, we have initiated baseline environmental monitoring studies, metallurgical and geotechnical studies for 2016. It is going to be a very exciting year for the Company and shareholders."

Core Drilling at Arrow Zone:

Three rigs have commenced drilling at the Arrow zone with all three using Devico directional drilling technology with the assistance of TECH Directional Services Inc. Two of the rigs are focused on delineating the Sub-Zone which was discovered during the summer 2015 drill program and is a zone of continuous higher grade uranium mineralization spanning 203 m in strike length that begins at less than 400 m below surface and remains open in all directions. The third rig is focused on expanding high-grade uranium mineralization within the A2 and A3 shears further to the southwest.

A fourth rig scheduled to commence on January 14th will initially focus in and around hole AR-15-36 where uranium mineralization was intersected just 4.0 m below the Athabasca Sandstone and basement unconformity. These holes will be testing for flat-lying mineralization at the unconformity in an area that is up-plunge from known basement mineralization.

Drilling Along Strike of Arrow Zone and Patterson Corridor:

A fifth rig, scheduled to commence late January, will systematically test along strike of the VTEM conductor that hosts the Arrow zone both to the southwest and northeast where there are numerous target areas with similar geophysical characteristics as Arrow. This will incorporate NexGen’s drilling philosophy of aggressive step-outs to test the aerial extent of mineralization which would then be followed by delineation.

Drilling Bow Discovery and Prospective Anomalies on Patterson Lake:

A sixth rig is scheduled to commence in early February to further test the Bow discovery and other highly prospective radon, VTEM, magnetic and gravity anomalies on Patterson Lake. Drilling at Bow will commence when ice conditions permit and will begin with step-out drilling from known mineralization in hole BO-15-10 which returned 9.5m at 0.20% U3O8 including 1.0m at 1.44% U3O8 (see News Release dated June 30, 2015). Further drilling will test coincident VTEM and radon-in-lake water anomalies and structural traps interpreted from previous drilling and geophysical surveys.

Other Activities in 2016:

Beyond this large winter 2016 drill campaign, the Company will continue baseline environmental monitoring as well as initiate multiple geotechnical and metallurgical testing during 2016 which will form the basis of future studies. Additionally, the Company will continue active engagement with local stakeholders and has applied for permits to build an all-weather access road to the Rook I camp to facilitate improved site logistics, efficiency, safety and support to the project.
