NexGen announced further results from their ongoing spring drilling program on their 100% owned Rook I Property, Athabasca Basin, Saskatchewan. Drilling at the area 180 m southwest of Arrow has intersected significant off-scale radioactivity associated with extensive visible uranium mineralization. All 3 holes in this area have intersected off-scale mineralization.
A total of 11 drill holes have now encountered mineralization in this area, which remains    open in    all directions and has currently established a strike length of 76 m (228 ft). Future drilling will be directed to determine whether this area which    is 180 m (540 ft) southwest of Arrow, is connected to Arrow to the northeast, and the extent of the area further to the southwest.

Hole AR-16-90c3, which was drilled 74 m up-dip and southwest of hole AR-16-77c2 has    intersected 8 m    of total composite off-scale radioactivity (10,000 to plus 61,000 cps)    marked by dense accumulations of massive to semi-massive pitchblende within 68.0 m of total composite mineralization. Included as part of the 8 m of off-scale mineralization 1.5 m of minimum-greater-than-61,000 cps. This is the most significantly mineralized hole to date at this newly identified area.

This announcement has been included in the I2M Web Portal because of the potential significance of the discovery, which could be the largest, and highest grade, uranium deposit discovered in the world to date. However, the grades have been reported in terms of radioactivity, not chemical grade. How much of the radioactivity is related to the actual uranium or to the radioactive daughter products will be determined in the laboratory, and no doubt reported soon.

Another factor is the depth of the deposit, which ranges from 300 m (900 ft) to 700 m (2,100 ft) bgs. This will have to be mined by underground methods one day, but the mining conditions will be challenging in such a hot environment, both temperature and radioactivity, perhaps via robotics.
