NexGen Announces Maiden Preliminary Economic Assessment of the Arrow Deposit

NexGen Energy Ltd. (“NexGen” or the “Company”) (TSX:NXE, NYSE:NXE) is pleased to announce the positive results of its independent maiden Preliminary Economic Assessment (“PEA”) of the basement-hosted Arrow Deposit, located on the Company’s 100% owned Rook I project in Saskatchewan’s Athabasca Basin.
The maiden PEA was completed by Roscoe Postle Associates Inc. (“RPA”), and is based on the mineral resource estimate announced by the Company in March 2017(with an effective date of December 20, 2016) that comprised an Indicated Mineral Resource of 179.5 M lb of U3O8 contained in 1.18 M tonnes grading 6.88% U3O8, and an Inferred Mineral Resource of 122.1 M lb of U3O8 contained in 4.25 M tonnes grading 1.30% U3O8. The PEA does not include the results of the Company’s winter or summer 2017 drill programs which will total over 66,000 m of additional drilling.
Leigh Curyer, CEO, commented:

“The Arrow Deposit is one of the most strategically significant and economically powerful mineral projects I am aware of across any resource commodity. Yet, it is still in it’s infancy in terms of ultimate resource size given the openness of mineralization and new discoveries in close proximity to Arrow highlighted in our recent drilling results.
This PEA highlights Arrow’s unique technical setting, grade and characteristics of mineralization, resulting in it hosting the potential to be a leading source of mined uranium in the world with a relatively low capital and operating cost per lb over the life of the mine.”
