Athabasca Basin uranium exploration and development company NexGen Energy (TSXV:NXE) has announced the first assay results from drill hole AR-14-15, completed during this summer's program at its wholly owned portion of the Rook I property. The AR-14-15 drill hole was angled to the northwest in order to target subvertical to steeply dipping mineralization at the Arrow discovery. What the results from drill hole AR-14-15 show is an upper high-grade uranium interval of 22.35 meters; it returned 3.42-percent U3O8 and includes 10.72-percent U3O8 over 6.85 meters, 15.74 percent over 4.5 meters and 26.1 percent over 2.6 meters. The highest-grade assay result within the interval shows 55.8-percent U3O8 over 0.45 meters. At a lower level, the high-grade intervals were found at 32 meters and have a grade of 1.52-percent U3O8, including 10.4-percent U3O8 over 3.15 meters. The highest-grade assay within the interval measures 43.7-percent U3O8 over 0.35 meters. As CEO Leigh Curyer said in the company's press release, NexGen's primary objective with the summer program was to establish a "large area of mineralization." That, said Curyer, was achieved quickly through aggressive, large step outs. "In only 22 holes, the team has established a mineralized zone of 515 x 180 m. Secondary, was to obtain an assessment on grade. These are the highest grade assay results over significant intervals to date at Arrow, which have exceeded expectation considering the stage of development. Arrow is developing faster than we ever anticipated at the beginning of the program," Curyer explained. As Resource Reports said on August 6, prior to the release of NexGen's assay results, the company's previous nine, widely spaced holes, five of which had off-scale radioactivity, provided investors with an "early glimpse to see if a guerilla is lurking in the jungle."
