Denison Mines Corp. (TSX: DML) (NYSE American: DNN) has filed its Condensed Consolidated Financial Statements and Management’s Discussion & Analysis for the quarter ended June 30, 2023. Both documents are or will be available on the Company’s website at www.denisonmines.com, SEDAR+ (at www.sedarplus.ca) and EDGAR (at www.sec.gov/edgar.shtml). The highlights provided below are derived from these documents and should be read in conjunction with them. All amounts in this release are in Canadian dollars unless otherwise stated.
David Cates, President and CEO of Denison commented, “During the second quarter, Denison achieved a further notable milestone associated with the advancement of our flagship Wheeler River Project with the completion of (i) a highly successful Feasibility Study evaluating the use of In-Situ-Recovery mining for the high grade Phoenix uranium deposit, and (ii) a positive cost update to the Pre-Feasibility Study for the underground mine planned for the Gryphon uranium deposit.
As outlined in the Phoenix FS, Denison has successfully completed several years of technical de-risking, which has cemented Phoenix’s position as one of the lowest-cost uranium development projects in the world. Notably, the economics of Phoenix as an ISR mining operation remain exceptionally robust, despite industry-wide cost inflation, while most contemporary uranium development projects have not yet been tested against current cost inflation. The recent results of the Phoenix FS and Gryphon Update illustrate Denison’s unique potential to become a meaningful uranium producer with multiple low-cost development assets.
Global support for the role of nuclear power in the clean energy transition continues to grow and uranium buyers are increasingly prioritizing geopolitical stability. Denison is well funded, with over $235 million in working capital and investments at the end of the second quarter, and focused on advancing Phoenix to a final investment decision in anticipation of building a much-needed new source of Canadian uranium production.”
In June 2023, Denison released the results of the Phoenix FS completed for ISR mining of Phoenix. The Phoenix FS demonstrates robust economics including:
The Phoenix FS reflects independent third-party validation of the selection of the ISR mining method for Phoenix and builds on the findings from a comprehensive and rigorous multi-year technical de-risking process highlighted by the highly successful completion of the leaching and neutralization phases of the Phoenix Feasibility Field Test in late 2022. Through the technical de-risking process, Denison has acquired extensive deposit-specific data and developed a robust ISR mine planning model that involved evaluation of the production potential for individual well patterns.
With technical de-risking of the project substantially complete, front-end engineering design efforts to support the advancement of the planned Phoenix operation are already significantly progressed and the Company is on track to transition into detailed design efforts, consistent with the Company’s Outlook for 2023, before the end of the year.
The scope of the Gryphon Update was targeted at the review and update of capital and operating costs. Mining and processing plans remain largely unchanged from the 2018 PFS aside from minor scheduling and construction sequencing optimizations. The key points include:
Importantly, Gryphon remains a highly valuable project that provides Denison with an additional source of low-cost potential production to deploy significant free cash flows expected from Phoenix.
Denison Mines Corp. was formed under the laws of Ontario and is a reporting issuer in all Canadian provinces and territories. Denison’s common shares are listed on the Toronto Stock Exchange (the ‘TSX’) under the symbol ‘DML’ and on the NYSE American exchange under the symbol ‘DNN’.
Denison is a uranium exploration and development company with interests focused in the Athabasca Basin region of northern Saskatchewan, Canada. The Company has an effective 95% interest in its flagship Wheeler River Uranium Project, which is the largest undeveloped uranium project in the infrastructure rich eastern portion of the Athabasca Basin region of northern Saskatchewan. In mid-2023, a Feasibility Study was completed for Wheeler River’s Phoenix deposit as an ISR mining operation, and an update to the previously prepared PFS was completed for Wheeler River’s Gryphon deposit as a conventional underground mining operation. Based on the respective studies, both deposits have the potential to be competitive with the lowest cost uranium mining operations in the world. Permitting efforts for the planned Phoenix ISR operation commenced in 2019 and have advanced significantly, with licensing in progress and a draft Environmental Impact Statement submitted for regulator and public review October 2022.
Denison’s interests in Saskatchewan also include a 22.5% ownership interest in the McClean Lake Joint Venture (‘MLJV’), which includes several uranium deposits and the McClean Lake uranium mill, which is contracted to process the ore from the Cigar Lake mine under a toll milling agreement, plus a 25.17% interest in the Midwest Main and Midwest A deposits and a 67.41% interest in the Tthe Heldeth Túé (‘THT,’ formerly J Zone) and Huskie deposits on the Waterbury Lake property. The Midwest Main, Midwest A, THT and Huskie deposits are located within 20 kilometres of the McClean Lake mill.
Through its 50% ownership of Japan (Canada) Exploration Company, Ltd), Denison holds additional interests in various uranium project joint ventures in Canada, including the Millennium project (JCU, 30.099%), the Kiggavik project (JCU, 33.8118%) and Christie Lake (JCU, 34.4508%).
Denison’s exploration portfolio includes further interests in properties covering approximately 285,000 hectares in the Athabasca Basin region.
Denison is also engaged in post-closure mine care and maintenance services through its Closed Mines group, which manages Denison’s reclaimed mine sites in the Elliot Lake region and provides related services to third party projects.
