Regional, Rook I

NexGen Energy holds the most dominant land position in the southwest Athabasca Basin of Saskatchewan. The Rook I property alone hosts the world-class Arrow Zone as well as the Bow discovery which was just discovered in early 2015.

A primary focus of the Company going forward will be to not only delineate Arrow in the most optimal way possible both in terms of cost and time, but also to try and determine what the entire Rook I property may hold. There are numerous high priority geophysical targets across the Rook I property as you travel southeast from the Patterson Conductor Corridor which hosts most of the known uranium mineralization in the southwest Athabasca Basin.

The Bow Discovery

On March 31, 2015 NexGen hit off-scale radioactivity 3.7 km northeast along the Patterson Lake Conductor corridor further inside the Athabasca Basin. Drill hole BO-15-10 intersected 2.5 m total composite mineralization including 0.10 m off-scale radioactivity (>10,000 to 10,200 cps) within a 5.0 m section (206.5 to 211.5 m). The Bow Discovery was made by targeting geophysical signatures similar to Arrow coincident with 'breaks' in the VTEM conductor along with radon in water surveys.

Winter 2016 Drilling

The Company will continue to advance Bow with planned holes to test coincident VTEM and radon in lake water anomalies, and structural traps interpreted from previous drilling and geophysical surveys. The Company will use its highly successful drilling methodology from Arrow on Bow as well by employing bold step outs and using angled drill holes.

While the Company will always maintain a deep focus on Arrow given its unique characteristics due to the fact it is land-based, basement-hosted and high-grade, we always believe it is prudent to decipher the potential value locked in the regional targets across the Rook I property, including the Bow discovery.
