NexGen Returns 13.5 m at 3.94% U3O8 including 2.5 m at 20.90% at Harpoon
Mar 23, 2017, 06:30 ET
VANCOUVER, March 23, 2017 /CNW/ - NexGen Energy Ltd. ("NexGen" or the "Company") (TSX:NXE, OTCQX:NXGEF) is pleased to report assay results for 20 holes from our 2016 drilling program on our 100% owned, Rook I property, Athabasca Basin, Saskatchewan.
Complete assay results have been received from all holes drilled at the Harpoon discovery and other regional target areas on the Rook I property from the 2016 drill program. At Harpoon, multiple holes have intersected uranium mineralization as well as encouraging alteration and narrow intervals of uranium mineralization was identified up to 2.3 km south of the Arrow Deposit. The mineralized footprint at Harpoon has been traced over a strike length of at least 340 m on the Rook I property, and remains open in all directions.
Highlights:
Harpoon Discovery
- HP-16-20 (73 m up-dip and northeast from discovery hole HP-16-08) intersected 13.5 m at 3.94% U3O8 (182.5 to 196.0 m) including 2.5 m at 20.90% U3O8 (187.0 to 189.5 m).
- HP-16-08 (Discovery Hole) intersected 17.5 m at 3.89% U3O8 (219.5 to 237.0 m) including 2.5 m at 12.49% U3O8 (224.5 to 227.0 m).
- HP-16-13 (33 m down-dip and southwest from HP-16-08) intersected 18.5 m at 1.17% U3O8 (211.5 to 230.0 m).
Furthermore, uranium mineralization has been confirmed for the first time 2.3 km south of the Arrow Deposit (see Figure 3). Regional holes RK-16-98, -100, -102, -104, -106 and -108 were drilled at a target area featuring a disrupted VTEM conductor and gravity low situated along a steep magnetic gradient, which presents a similar geophysical signature to that of the Arrow Deposit. All holes intersected widespread and intense hydrothermal alteration including near complete clay and silica replacement styles over tens of meters (see news release dated November 2, 2016). Holes RK-16-98 and -108 also intersected narrow zones of low grade uranium mineralization (see Table 1).
Arrow, Activities & Financial
- The 2017 winter program comprising a minimum of 35,000 m using seven drill rigs is currently underway.
- The Company has cash on hand of approximately $64 million.
A Harpoon long section as well as plan maps with hole locations are shown in Figures 1 to 3. Table 1 shows complete assay results.
Garrett Ainsworth, Vice-President, Exploration and Development, commented: "With only 24 drill holes, Harpoon has the potential to be a new uranium zone and speaks to how fertile the Patterson Corridor is for high-grade uranium. The ZTEM survey over the Patterson Corridor is a dynamic layer of geophysical data which complements our existing data, and will be used to further refine regional targets along the Patterson Corridor in the future."
Leigh Curyer, Chief Executive Officer, commented: "The Harpoon assays and the early results 2.3km to the southwest of Arrow highlight the vast prospectivity of the entire Patterson Corridor of which NexGen owns 9km of strike on the Rook I property. With the recent updated mineral resource estimate validating Arrow as a strategic mineral asset, but in the early stage of ultimate definition, it demands 100% of the focus and metres given its obvious growth potential. Without taking anything away from these terrific results at Harpoon and the clear potential for additional discoveries along the Patterson Corridor, the winter 2017 campaign is focused within a 1 km radius of Arrow where the growth is evidenced by the recent results of broad and sub interval high-grade intercepts in the A2 and A3 shears to the northeast and also to the southwest towards the 180 m zone."

Composite parameters:
- Minimum thickness 0.5 m downhole
- Cutoff grade 0.01% U3O8
- Maximum internal dilution 2.00 m downhole
- U3O8 analyzed by ICP-OES at SRC Geoanalytical Laboratories, Saskatoon, Saskatchewan
- Harpoon drill hole (HP-16-XX) true widths are estimated to be approximately 55-90% of core lengths.
- *Uranium analyzed by ICP-MS at SRC Laboratories and converted from parts per million to percent
Split core samples were taken systematically, and intervals were submitted to SRC Geoanalytical Laboratories (an SCC ISO/IEC 17025: 2005 Accredited Facility) of Saskatoon for analysis. All samples were analyzed using ICP-MS for trace elements on partial and total digestions, ICP-OES for major and minor elements on a total digestion, and fusion solution of boron by ICP-OES. Mineralized samples were analyzed for U3O8 by ICP-OES and selected samples for gold by fire assay.
All assay batches reported herein are subjected to and have passed rigorous internal QA/QC protocols that include, but are not limited to, the blind insertion of standard reference materials, blank materials and field duplicates into the sample stream at both random and systematic intervals. Please see the Rook I Technical Report (as defined below) for detail of our QA/QC protocols.

Such forward-looking information and statements are based on numerous assumptions, including among others, that the results of planned exploration activities are as anticipated, the price of uranium, the anticipated cost of planned exploration activities, that general business and economic conditions will not change in a material adverse manner, that financing will be available if and when needed and on reasonable terms, and that third party contractors, equipment and supplies and governmental and other approvals required to conduct the Company's planned exploration activities will be available on reasonable terms and in a timely manner. Although the assumptions made by the Company in providing forward-looking information or making forward-looking statements are considered reasonable by management at the time, there can be no assurance that such assumptions will prove to be accurate.
Forward-looking information and statements also involve known and unknown risks and uncertainties and other factors, which may cause actual events or results in future periods to differ materially from any projections of future events or results expressed or implied by such forward-looking information or statements, including, among others: negative operating cash flow and dependence on third party financing, uncertainty of additional financing, no known mineral reserves, assay results may not be consistent with preliminary results, alternative sources of energy, aboriginal title and consultation issues, reliance on key management and other personnel, potential downturns in economic conditions, actual results of exploration activities being different than anticipated, changes in exploration programs based upon results, availability of third party contractors, availability of equipment and supplies, failure of equipment to operate as anticipated; accidents, effects of weather and other natural phenomena and other risks associated with the mineral exploration industry, environmental risks, changes in laws and regulations, community relations and delays in obtaining governmental or other approvals.
Although the Company has attempted to identify important factors that could cause actual results to differ materially from those contained in the forward-looking information or implied by forward-looking information, there may be other factors that cause results not to be as anticipated, estimated or intended. There can be no assurance that forward-looking information and statements will prove to be accurate, as actual results and future events could differ materially from those anticipated, estimated or intended. Accordingly, readers should not place undue reliance on forward-looking statements or information. The Company undertakes no obligation to update or reissue forward-looking information as a result of new information or events except as required by applicable securities laws.
