TORONTO, Dec. 31, 2020 (GLOBE NEWSWIRE) — McEwen Mining Inc. (NYSE: MUX) (TSX: MUX) is happy to announce the highlights of a optimistic Feasibility Research (FS) for its 100%-owned Fenix Venture, which is positioned within the State of Sinaloa, Mexico.
“The Fenix Feasibilty Research envisions a 9.5-year mine life with a sexy after-tax IRR of 28% utilizing $1,500/oz gold and $17/oz silver. At present gold and silver costs, the challenge’s after-tax IRR nearly doubles and the NPV greater than triples versus the bottom case.
The challenge will incorporate an environmentally progressive methodology of tailings administration, utilizing inpit storage that creates a number of advantages, most significantly a safe containment of tailings enabling higher reclamation outcomes.
Common annual manufacturing is projected at 26,000(1) oz gold in Section 1 and 4,200,000(4) oz silver equal in Section 2. The essential path environmental permits are in hand for the primary part of manufacturing. Our subsequent steps will contain detailed engineering, evaluation of procurement choices, and the analysis of financing alternate options,” mentioned Rob McEwen, Chairman and Chief Proprietor.
Fenix FS Highlights
|Base Case(1)$1,500/oz Gold, $17/oz Silver||Upside Case$1,900/oz Gold, $25/oz Silver|
|After-Tax NPV (8% low cost)||$32 million||$98 million|
|After-Tax Payback Interval||3.6 years||2.8 years|
|Common After-Tax Money Circulate per Yr of Full Manufacturing||$12 million||$25 million|
|The FS for challenge Fenix growth entails two phases:|
|Section 1: Years 1 to six, Gold Manufacturing|

Feasibility Research Report
The entire Fenix Venture FS NI 43-101 Technical Report will probably be accessible on www.sedar.com and www.mcewenmining.com inside 45 days. The FS was ready by GR Engineering Providers Restricted (“GRES”) of Belmont, Western Australia, in accordance with the necessities of Canadian Nationwide Instrument 43-101 “Requirements of Disclosure for Mineral Tasks” (“NI 43-101”) and SEC Trade Information 7.
The present operation at El Gallo Gold is a completely permitted website; allow for the Section 1 was granted by the Federal Environmental Authority (SEMARNAT) in September 2019, for the addition of a mill and leach circuit within the location of the present amenities for the reprocessing of the heap leach pad materials. The allow modification additionally consists of the backfilling of a beforehand mined pit with mill tailings, as a part of an built-in concurrent closure plan for the El Gallo Gold Mine.
Additional challenge development for Section 2 is topic to allow approvals. Section 2 challenge allowing would require authorization to increase the method plant footprint at El Gallo Gold and the haul street, and to enhance the tailings quantity to be deposited on the depleted pit.
The Fenix Venture has CONAGUA approval for the extraction of groundwater and land-use permits for the development of wells required for the lifetime of Fenix Venture.
Useful resource Estimates
Estimated sources for the Fenix Venture are comprised solely of fabric inside the boundaries of conceptual pit shells, apart from the El Gallo heap leach pad, which is taken into account fully accessible for reprocessing.
For the needs of mine scheduling, the contained gold ounces within the Heap Leach Materials has been depleted from the useful resource mannequin estimate outlined by drilling by an quantity of 23 koz Au, to account for the manufacturing from heap leach operations and gold in circuit assessments between the timing of the useful resource estimate up till December 2020.

FOOTNOTES (1) The Base Case makes use of the three-year shifting common costs for gold and silver (approximate worth). Estimated 26,000 oz Au every year manufacturing assumes full manufacturing from years 2023 to 2027. Common after-tax money movement every year from full manufacturing years 2023 to 2031 is roughly $12 million every year. Common after-tax money flows every year for the interval from start-up of manufacturing to closure (2022 to 2032) is roughly $8.6 million every year. These money flows assume the usage of all eligible tax loss carry forwards from the El Gallo Gold Mine.(2) Money value is calculated by dividing complete life-of-mine manufacturing prices, basic and administrative bills and royalties by complete ounces produced.(3) All-in sustaining prices (AISC) are calculated by dividing the sum of all money prices plus sustaining capital and reclamation prices by complete ounces produced.(4) All references to AgEq are primarily based on an 88 Ag oz to 1 Au oz ratio. For Section 1 silver accounts for CIM Definition Requirements, and the CIM Estimation of Mineral Assets and Mineral Reserves Greatest Apply Tips of November 2019, and have been transformed solely from these parts of the Mineral Assets which might be categorised as Measured or Indicated Mineral Useful resource classes after having been evaluated with consideration of all recognized modifying elements affecting financial viability.(9) Reduce-off grades fluctuate by pit in keeping with financial, restoration and metallurgical parameters.
