Drill hole AR-15-37 showed 16.5m at 2.46% U3O8, including 3m at the rate of 12.85% U3O8; and 40m at the rate of 2.88% U3O8, including 22m at the rate of 4.92% U3O8; AR-15-38 assays 32m at 0.90% U3O8.
Arrow Zone, which is open in all directions and at depth, is currently 515m by 215m with the vertical extent of mineralization commencing from 100m and extending down to 820m.
NexGen exploration and development vice-president Garrett Ainsworth said: "The high grade core of the A2 mineralized structure at the Arrow zone is further bolstered by drill hole AR-15-37, and has been expanded to a strike length of 88 m from AR-14-15 to AR-15-38.
"These strong assay values are a result of our technical team’s thoroughness and dedication to understand the structures that control mineralization, and to successfully predict where additional high grade is present."
Split core samples have been collected and intervals were submitted to SRC Geoanalytical Laboratories, which analyzed the split core samples for U3O8 by ICP-OES, ICP-MS for trace elements on the partial and total digestions and fusion solution of boron by ICP-OES.
Earlier this week, the company announced assay results for the first four drill holes, including AR-15-34b, AR-15-35 and AR-14-36.
