NexGen Energy Ltd. is a Canadian company focused on delivering clean energy fuel for the future. It is engaged in the acquisition, exploration and evaluation and development of uranium properties in Canada. It is focused on optimally developing the Rook I Project. It has a portfolio of highly prospective projects, including its 100% owned Rook I property that is host to the high-grade Arrow Deposit, South Arrow, Harpoon, Bow, and the Cannon area. The Rook I Project is a development-stage uranium project in Canada. The new underground mine and mill development is located in the uranium-rich district of the southwestern area of the Athabasca Basin, located in Saskatchewan. Arrow is a 100% land-based, basement-hosted, and high-grade uranium discovery. The Rook I Project, host of the Arrow Deposit, which is a development-stage uranium project in Canada and is 100% owned by NexGen Energy Ltd. The Rook I property hosts the Harpoon Discovery located 4.7 km northeast of the Arrow Deposit.

RE:RE:RE:RE:RE:Was that a 100 million lb hole?

They first suggested a long-term resouce of 200mm lbs in August: https://app.box.com/s/q40p740jshln9dxfbpgfbnimiwc1ku9r

RJ>>>>>Accordingly, we believe the 125 Mlbs which supports our valuation today is very conservative and we would not be surprised to see the maiden 43-101 estimate range between 150 and 200 Mlbs in contained metal at average grades well over 1% U3O8 (depending on cut-off).

BobbiOre wrote: No matter parameters we use it is one crazy hole. That said i cannot image the resource estimate coming in below 200 million lbs. Plus it remains wide open. Could Arrow ultimately contain 400 million lbs. Dont be suprised!

letsgetready wrote: RJ gave it 95 million pounds based on a 25 m sphere of influence for inferred resources. >>>from RJ: If one assumes a 25 m radius of influence what resource engineers at SRK are said to be allowing for the Inferred category at Arrow a hole like 62 running 70 m of 10% U3O8 on paper adds a mind-numbingly high ~95 Mlbs of contained uranium.

(124 m high, 50 m wide, 50 m thick, 3 specific gravity, 6.35%, do the math).

There are no doubts left as to who has the biggest, best new discovery in the last 25 years in the basin.

Drilled at a dip angle of -76 degrees, the true width is 30m and vertical extent 120.3m.

So 30m strike * 30m width * 120.3m depth * 6.35% * 2.75 tonnes/m^3 * 2204.62 lbs/tonne = 43mm lbs in hole 62 alone.

Total for A2 ultra high-grade subcore actually drops to 160mm lbs per my estimate. Again this is just for the ultra high grade subcore within the A2 high grade core. FWIW, I estimate total inventory at a minimum 260mm lbs.

I calculated ore density as follows: 2.4 t/m3 for gneiss and 8.0t/m3 for pitchblende; 93.65% gneiss and 6.35% pitchblende; (93.65%*2.4) + (6.35%*8.0) = 2.7556
