NexGen Commences 125,000 m Feasibility Stage Drilling Program and Technical Studies at the Arrow Deposit

PR Newswire

VANCOUVERJan. 21, 2019 /PRNewswire/ – NexGen Energy Ltd. (“NexGen” or the “Company”) (TSX: NXE, NYSE MKT: NXE) is pleased to announce that the largest drill program in the Company’s history focused on optimizing mine development has begun at our 100% owned, Rook I property, in the AthabascaBasin, Saskatchewan. The drill program results will be incorporated into a NI43-101 Bankable Feasibility Study (“FS” or the “Study”), building on the successful outcomes highlighted in the Company’s Pre-Feasibility Study (“PFS”) (see News Release dated November 5, 2018) which demonstrated the Arrow Project to be an exceptional development opportunity for NexGen, Saskatchewan and Canada.

The development optimization program consists of a minimum 125,000 m using 10 diamond drill rigs focusing on three objectives:

  1. Convert High Grade Indicated Mineral Resources to Measured Mineral Resources: Approximately 71,000 m will be drilled at a spacing sufficient to support the conversion of the currently defined high-grade (“HG”) Indicated Resource (currently 256.6 M lbs of U3O8 contained in 2.89 M tonnes grading 4.03% U3O8) to Measured Resource. Measured Mineral Resources represent the highest level of mineral resource estimate, providing a significant amount of technical detail on the FS mine plan, design and economics.
  2. Covert Inferred Mineral Resources to Indicated Mineral Resources: Approximately 54,000 m will be drilled to support the conversion of part of the currently defined Inferred Resource (currently 91.7 M lbs of U3O8 contained in 4.84 M tonnes grading 0.86% U3O8) to an Indicated Resource. Further conversion of Inferred to Indicated Mineral Resources will optimise the usable mineral inventory for the FS mine plan which can only incorporate Indicated or higher classification resources in compliance with the NI 43-101 guidelines.  Given the strong continuity of mineralization seen at Arrow, the conversion of Inferred to Indicated resources since delineation drilling commenced has been very efficient and predictable.
  3. Geotechnical and Hydrogeological Characterization: Approximately 12,500 m of the 125,000 m will also incorporate the geotechnical and hydrogeological characterization of the rock mass in the areas of potential mine development and Underground Tailings Management Facility (“UGTMF”).  This additional analysis will build upon the significant geotechnical, hydrogeological and metallurgical testing that has been incorporated into the PFS.

The 125,000 m of drilling outlined above will be added to the existing 296,000 mof drill data collected to date by NexGen to form the basis of an FS which will incorporate an updated Mineral Resource Estimate and scheduled for release in H1/2020.  The FS will increase design detail to a resolution necessary to support at a minimum a Class 3 cost estimate (AACE International standard). The objectives of the FS are as follows:

  • Further optimization of the proposed development of the Arrow Deposit with respect to mine design (stope layouts, development, and production schedule) based on only Measured and Indicated mineral resources,
  • Defining a level of design to support the comprehensive Environmental Assessment applications,
  • Engaging with construction experts to optimize construction sequencing, utilization of pre-fabrication, offsite module assembly, and identify alternative opportunities to advance project development timelines,
  • Continuing the advancement of the UGTMF design to optimize tailings density and further reduce tailings volumes enabling the opportunity to minimize the surface footprint of the mine,
  • Leveraging opportunities for capital cost optimization while increasing confidence in the capital and operating cost estimates,
  • Integrating innovative but proven mining, milling and environmental technologies and sustainable practices including the evaluation of alternative energy solutions to further increase NexGen’s sustainability commitment.

Drilling program target areas can be found in the figures 1 and 2.

Financial

  • The Company has cash on hand of approximately ~$110 million.

Leigh Curyer, President and Chief Executive Officer, commented: “This year’s drill program will be the largest in the Company’s history to date, and reportedly, in Canada for a uranium project in 2019. The team has focused considerable effort into the planning of the drill program and technical studies, which leverages our experience in optimizing mine development, processing and elite environmental management practices. With the opening this week of the new Saskatoon project office, which has been designed at a capacity to take NexGen through to reaching its objective of becoming a major producer of uranium on the world stage, it is very exciting times for the NexGen team and Saskatchewan.”

Troy Boisjoli, Vice-President, Operations and Project Development, commented: “The technical characteristics of the Arrow deposit has allowed for rapid growth and increased confidence through each successive drill program. This is an exciting time at NexGen, focussing on continued advancement of the Arrow deposit through the requisite development stages.”

U.S. investors are advised that while the terms “indicated resources” and “inferred resources” are recognized and required by Canadian regulations, the U.S. Securities and Exchange Commission does not recognize these terms. U.S. investors are cautioned not to assume that any part or all of the material in these categories will ever be converted into mineral reserves.

SEC Standards

Estimates of mineralization and other technical information included or referenced in this news release have been prepared in accordance with NI 43-101. The definitions of proven and probable mineral reserves used in NI 43-101 differ from the definitions in SEC Industry Guide 7. Under SEC Industry Guide 7 standards, a “final” or “bankable” feasibility study is required to report reserves, the three-year historical average price is used in any reserve or cash flow analysis to designate reserves and the primary environmental analysis or report must be filed with the appropriate governmental authority. As a result, the reserves reported by the Company in accordance with NI 43-101 may not qualify as “reserves” under SEC standards. In addition, the terms “mineral resource”, “measured mineral resource”, “indicated mineral resource” and “inferred mineral resource” are defined in and required to be disclosed by NI 43-101; however, these terms are not defined terms under SEC Industry Guide 7 and normally are not permitted to be used in reports and registration statements filed with the SEC. Mineral resources that are not mineral reserves do not have demonstrated economic viability. Investors are cautioned not to assume that any part or all of the mineral deposits in these categories will ever be converted into reserves. “Inferred mineral resources” have a great amount of uncertainty as to their existence, and great uncertainty as to their economic and legal feasibility. It cannot be assumed that all or any part of an inferred mineral resource will ever be upgraded to a higher category. Under Canadian securities laws, estimates of inferred mineral resources may not form the basis of feasibility or pre-feasibility studies, except in rare cases. Additionally, disclosure of “contained pounds” in a resource is permitted disclosure under Canadian securities laws; however, the SEC normally only permits issuers to report mineralization that does not constitute “reserves” by SEC standards as in place tonnage and grade without reference to unit measurements. Accordingly, information contained or referenced in this news release containing descriptions of the Company’s mineral deposits may not be comparable to similar information made public by U.S. companies subject to the reporting and disclosure requirements of United Statesfederal securities laws and the rules and regulations thereunder.
