  • Wheeler River Project Provincial Technical Proposal and Federal Project Description
    Wheeler River Project Provincial Technical Proposal and Federal Project Description Denison Mines Corp. May 2019 WHEELER RIVER PROJECT TECHNICAL PROPOSAL & PROJECT DESCRIPTION Wheeler River Project Provincial Technical Proposal and Federal Project Description Project Summary English – Page ii French – Page x Dene – Page xx Cree – Page xxviii PAGE i WHEELER RIVER PROJECT TECHNICAL PROPOSAL & PROJECT DESCRIPTION Summary Wheeler River Project The Wheeler River Project (Wheeler or the Project) is a proposed uranium mine and processing plant in northern Saskatchewan, Canada. It is located in a relatively undisturbed area of the boreal forest about 4 km off of Highway 914 and approximately 35 km north-northeast of the Key Lake uranium operation. Wheeler is a joint venture project owned by Denison Mines Corp. (Denison) and JCU (Canada) Exploration Company Ltd. (JCU). Denison owns 90% of Wheeler and is the operator, while JCU owns 10%. Denison is a uranium exploration and development company with interests focused in the Athabasca Basin region of northern Saskatchewan, Canada with a head office in Toronto, Ontario and technical office in Saskatoon, Saskatchewan. Historically Denison has had over 50 years of uranium mining experience in Saskatchewan, Elliot Lake, Ontario, and in the United States. Today, the company is part owner (22.5%) of the McClean Lake Joint Venture which includes the operating McClean Lake uranium mill in northern Saskatchewan. To advance the Project, Denison is applying an innovative approach to uranium mining in Canada called in situ recovery (ISR). The use of ISR mining at Wheeler means that there will be no need for a large open pit mining operation or multiple shafts to access underground mine workings; no workers will be underground as the ISR process is conducted from surface facilities.

  • Denison Reports a Year of Significant Project and Company De-Risking
    Denison Mines Corp. 1100 – 40 University Ave Toronto, ON M5J 1T1 www.denisonmines.com PRESS RELEASE Denison Reports a Year of Significant Project and Company De-Risking Toronto – March 4, 2021 Denison Mines Corp. (“Denison” or the “Company”) (DML: TSX) (DNN : NYSE American) today filed its Audited Consolidated Financial Statements and Management’s Discussion & Analysis (“MD&A”) for the year ended December 31, 2020. Both documents can be found on the Company’s website at www.denisonmines.com or on SEDAR (at www.sedar.com) 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, “Confronted with the varied challenges of the global COVID-19 pandemic, Denison’s resilient teams excelled in 2020 and early 2021 – accomplishing a significant de-risking of our flagship Wheeler River project and the Company’s balance sheet. At Wheeler River, our technical team achieved a key milestone, receiving an independent confirmation of ‘Proof of Concept’ for the application of the In-Situ Recovery (‘ISR’) mining method at the high-grade Phoenix deposit. We also completed an important trade-off study leading to the adoption of a freeze ‘wall’ design for containment of the ISR operation at Phoenix – a decision that is expected to be favourable from an environmental standpoint, reduce technical complexity and operational risks, allow for a phased mining approach with lower up-front capital costs, and strengthen project sustainability.

  • METALS 497 Quebec's Output of Silver Comes Mainly from Its Copper Ores
    METALS 497 Quebec's output of silver comes mainly from its copper ores. The principal producers in 1957 were Noranda Mines Limited, Golden Manitou Mines Limited, Normetal Mining Corporation Limited, Quemont Mining Corporation Limited, Barvue Mines Limited, New Calumet Mines Limited, Gaspe Copper Mines Ltd., East Sullivan Mines Limited, Waite Amulet Mines Limited, Campbell Chibougamau Mines Ltd. and Opemiska Copper Mines (Quebec) Limited. Heath Steele Mines Limited, the only producer in New Brunswick, recovered silver from its base-metal operations but was forced to curtail its operations sharply in 1958. Buchans Mining Company Limited of Newfoundland also obtained silver from base-metal concentrates. Development work involving silver values has been mentioned under the headings of Copper and Lead and Zinc. Projects of interest in 1957 and 1958 involved the Chisel Lake area, under development by Hudson Bay Mining and Smelting Co. Limited; the base-metal property of Consolidated Sudbury Basin Mines Limited; the zinc-silver-lead deposit of The Coniagas Mines Limited at Bachelor Lake, Que.; the drilling program undertaken by the Mattagami Syndicate at Watson Lake; and the zinc-lead-copper deposits near Bathurst which, for a time, were under study by Brunswick Mining and Smelting Corporation Limited, and by Nigadoo Mines Limited. Unfortunately the continuing slump in the base-metals market has forced some of these projects to be curtailed. Uranium.—Uranium production registered spectacular gains in 1957-58. Annual output of the oxide soared from 2,281 tons at $45,732,145 in 1956 to 6,635 tons at $136,304,364 the following year; and preliminary figures for 1958 of 14,118 tons at $290,228,356 show a continuation of the upward trend.

It contains 9.15 million (M) lb. U3O8 in the Indicated category and a further 1.13 M lb. in the Inferred category. The overall grade is just above 0.1% U3O8. • UEX announced that it and operator AREVA have identified a zone of continuous unconformity mineralisation between the Kianna and Anne deposits with a strike length of at least 900 m. • Claude Resources reported final 2008 gold production results for the Seabee Mine, including ore from the satellite Santoy 7 deposit, of 45,466 oz., 13,551 oz. of which was in the fourth quarter. • Golden Band Resources Inc. announced the completion of an independent pre- feasibility study for its La Ronge Gold Project. The independent consultants concluded that the operating plan for the proposed four-year project is economically viable based on the open pit mining of the Komis and EP gold deposits, underground mining of the Bingo gold deposit, and use of the existing Jolu mill.
