NexGen Energy Ltd. (TSXV:NXE) discovered off-scale radioactivity, “Bow Discovery”, approximately 3.7 km northeast and along trend from the Arrow zone in the Rook I property, Athabasca Basin. Bow is now a high priority area, and is coincident with the recent radon anomaly that tracks the strike of a VTEM conductor from 730m up to 140m wide. This particular radon anomaly has the highest reading of all known radon anomalies in the area with a peak reading of 36.0 pCi/L, and is 80 m south of off-scale radioactivity drilled in hole BO-15-10.
As quoted in the press release:
Highlights:
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) associated with veinlets, flecks and blebs of pitchblende within a sheared, strongly chlorite altered pelitic gneiss (mylonite). BO-15-10 is a 66.0 m step out to the east of BO-15-02, where lake depths range between 2.1 to 2.2m;
BO-15-02 intersected 3.0 m discrete mineralization (202.0 to 205.0 m) from Drill holes BO-15-02 and -10 targeted a coincident VTEM conductor and radon in lake water anomaly with a peak reading of 36.0 pCi/L (Figure 3);
Multiple radon anomalies have been discovered along the northeast 3.7 km VTEM conductor from Arrow, and on the parallel VTEM conductor to the north as shown in Figure 2. These radon anomalies are optimally situated along breaks and kinks in the VTEM conductors.
The 2015 winter drilling program has been expanded to a minimum 20,000 meters. Drilling will continue to focus on Arrow expansion at the two high grade core zones in A2 and A3, and on step outs from the discovery holes BO-15-02 and -10 at Bow.
Figure 2 shows radon in lake water results and drilling to the northeast of the Arrow zone. Figure 3 shows the Bow Discovery drill hole locations and anomalous radon results. Drill core photos of BO-15-10 are shown in Figures 4 and 5. Drill hole details and spectrometer (handheld RS-120 scintillometer) results are summarized in Table 1.Garrett Ainsworth, NexGen’s Vice-President, Exploration and Development, commented “Drill holes BO-15-02 and -10 have already defined a 66 m strike length of mineralization at our Bow Discovery, which underpins the immense potential to discover additional mineralization to the northeast and along trend from the Arrow zone. This successful step-out 3.7 km to the northeast of Arrow is a result of drill testing coincident VTEM and radon in lake water anomalies, which has proven to be effective when utilized in the appropriate geological setting in the Athabasca Basin. The VTEM conductor that hosts Arrow extends for approximately 5 km to the northeast before reaching our claim boundary, and the NexGen team is very encouraged with this new discovery.”
Leigh Curyer, Chief Executive Officer commented, “This new discovery of uranium mineralization at Bow is another significant step forward in unlocking the substantial prospectivity of the Rook I property. Coupled with the rapid development at Arrow discovered just over 12 months ago, it is incredibly exciting for shareholders to now have two discoveries developing in proximity to one another. I would like to take the opportunity to acknowledge the contribution of the entire team, including Board and Technical Committee members at NexGen, who have shown outstanding commitment and expertise to develop the Company into a premier exploration and development organization in such a relatively short period of time. Garrett Ainsworth, and his technical team continually demonstrate their expertise in making new discoveries and developing projects in a highly efficient and optimal manner.”
