24 Mar 2026resource reserve update▲ GoodMajor
McEwen published its first formal resource estimate for the newly acquired Tartan Mine (308,900 oz Indicated, 302,700 oz Inferred gold), targeting an initial ~30,000 oz/year restart as part of a broader plan to roughly double the company's total gold production to 250,000-300,000 oz by 2030.
20 Jan 2026resource reserve update▲ GoodMajor
New step-out drilling at the newly acquired Tartan Mine project extended high-grade gold mineralization further along its Western Flank, while McEwen separately released its year-end 2025 resource update for Grey Fox.
9 Oct 2025resource reserve update▲ GoodMajor
The bankable Feasibility Study for Los Azules confirmed a massive, economically strong project - $2.9 billion after-tax NPV, 19.8% IRR, 21-year mine life averaging 148,200 tonnes/year of copper cathode - while McEwen Inc.'s own stake in the McEwen Copper vehicle has further thinned to 46.4% as outside capital (now including a strategic collaboration with the IFC on potential project debt financing) keeps funding it toward construction.
4 Sept 2025resource reserve update▲ GoodMajor
McEwen reported strong new drill results at Grey Fox (Gibson and GFS zones) ahead of an October 2025 resource update, and separately announced a new high-grade gold discovery at its Windfall project in Nevada.
6 Oct 2023drilling result▲ GoodMajor
McEwen reported new assay results from the Stock property at its Fox Complex and filed the formal SEC-compliant (S-K 1300) technical report summary for Los Azules, putting the resource estimate behind June's PEA on official U.S. regulatory footing.
21 June 2023resource reserve update▲ GoodMajor
A major new Los Azules study built around heap-leaching and cathode production (rather than a conventional concentrator) showed a $2.659 billion after-tax NPV and 21.2% IRR, with the resource itself growing to 10.9 billion lbs of Indicated copper - though the leach-cathode design requires $2.46 billion of initial capital, and McEwen Mining's own stake in the Los Azules vehicle has fallen further to 52% as outside capital keeps funding it.
26 Jan 2023drilling result▲ GoodMajor
More Los Azules assay results showed thick, high-grade copper intercepts (up to 237 meters at 1.05% copper), including one deep hole that intersected mineralization as far as 1,100 meters down - underscoring the deposit's scale as drilling continued.
7 Sept 2022farm in farm out agreement▲ GoodMajor
McEwen Copper signed a deal letting Rio Tinto subsidiary Kennecott Exploration earn a 60% interest in the Elder Creek copper project in Nevada by spending $18 million over up to seven years and operating it, after which the two would form a 60:40 joint venture - a non-dilutive way to fund exploration on a secondary asset while McEwen retains a 1.25% royalty.
4 Aug 2022drilling result▲ GoodMajor
New Los Azules drilling returned long, high-grade copper intercepts (including 222 meters at 0.95% copper), part of a program aimed at upgrading resources and testing depth extensions ahead of an updated economic study due in early 2023; independent analysts ranked Los Azules among the world's five largest undeveloped copper deposits not already owned by a major miner.
27 Jan 2022resource reserve update▲ GoodMajor
A new economic study for the Fox Complex in Timmins showed a 12-plus-year mine life averaging nearly 72,000 oz/year of gold at under $800/oz cash cost, building on the Froome mine's successful 2021 startup; McEwen hired Wood Canada to help decide how to unlock further value from the wider Fox property package.
23 Feb 2021resource reserve update● NeutralMajor
McEwen filed the formal, bankable feasibility study confirming Gold Bar's reduced reserve base: a 6-year mine life producing 302,000 oz of gold, with an after-tax NPV of $55.2 million at $1,500/oz.
17 Feb 2021resource reserve update▲ GoodMajor
McEwen filed the full feasibility study for Project Fenix at El Gallo: a 9.5-year mine life in two phases (gold, then silver) with a 28% after-tax IRR at $1,500 gold, permits for Phase 1 already in hand, and next steps focused on engineering and financing.
7 Jan 2021resource reserve update▼ BadMajor
McEwen confirmed the Gold Bar reserve cut it had flagged in Q1 2020: Probable Reserves are now 302,000 oz, a net 16% reduction from the 430,000 oz estimated when mining started in 2019, after allowing for 58,600 oz mined. After-tax NPV is $62-76 million at $1,500/oz gold.
18 June 2020resource reserve update● NeutralMajor
McEwen's Black Fox mine, which had been suspended for three weeks in the spring due to COVID-19, was back operating under health guidelines with no new local cases reported since May, while underground exploration drilling turned up promising high-grade gold results extending the mine to the west.
25 July 2019resource reserve update▲ GoodMajor
McEwen's Grey Fox deposit near Black Fox grew again - Indicated gold resources up 22% to 567,000 oz at 7.10 g/t and Inferred up 35% - driven by a new discovery zone (147NE) that a study is now evaluating for underground mining.
25 July 2018resource reserve update▲ GoodMajor
McEwen reported more encouraging results from its $15 million Black Fox exploration program, with 129,000 ft drilled in Q2, including at Stock East, Froome and Gibson. A revised Black Fox Mine resource eliminated the Inferred category and increased Indicated ounces and grade.
9 July 2018resource reserve update▲ GoodMajor
McEwen filed the finalized El Gallo mine-life-extension study ('Project Fenix') and explicitly corrected the numbers it had previewed six weeks earlier: mine life is actually 12 years (not 10), with a 28% after-tax IRR, $60 million NPV, $41 million initial capital and 47,000 oz/year of gold-equivalent production.
25 May 2018resource reserve update▲ GoodMajor
Three updates in one week: the Tamarack deposit at Black Fox got its first resource estimate including base metals (127,000 Indicated gold-equivalent oz, up from 41,000 Inferred oz), McEwen flagged a possible promissory-note financing for Gold Bar construction, and it previewed a new economic study extending El Gallo's mine life by about 10 years.
16 Feb 2018resource reserve update▲ GoodMajor
With construction already underway, McEwen updated the Gold Bar feasibility study: capital costs rose about 30% to $81 million after adding a crushing/agglomeration plant, but that lifts expected gold output 20% to an average 62,800 oz/year at a $770/oz cash cost, with production targeted for 2019.
17 Oct 2017resource reserve update● Neutral
McEwen filed the full technical report backing September's much-improved Los Azules economic study - a procedural SEDAR filing with no new figures.
8 Sept 2017resource reserve update▲ GoodMajor
A major new economic study for Los Azules showed sharply improved economics - an after-tax NPV of $2.2 billion (20.1% IRR), 3.6-year payback and 36-year mine life - after McEwen redesigned the project around a conventional flotation concentrator and phased 80,000-to-120,000-tonne-per-day throughput, helped by Argentina's removal of export taxes on mineral concentrates.
7 Dec 2015resource reserve update● Neutral
McEwen filed the full NI 43-101 technical report backing October's positive Gold Bar feasibility study on SEDAR - a procedural filing with no new figures.
21 Oct 2015resource reserve update▲ GoodMajor
A feasibility study for the Gold Bar project in Nevada came back positive - $60 million of initial capital, a 20% after-tax IRR at $1,150/oz gold, and average annual production of 65,000 oz at a $728/oz cash cost - positioning it as McEwen's next mine to build.
23 Sept 2013resource reserve update▲ GoodMajor
McEwen was added to the NYSE Arca Gold Miners Index, and days later released a much bigger milestone: an updated Los Azules economic study showing a pre-tax NPV of $3.0 billion (17.6% IRR) and after-tax NPV of $1.7 billion, with copper output averaging 255,000 tonnes/year in its first five years - output that would rank among the top 3% of copper mines worldwide.
7 Aug 2013resource reserve update▲ GoodMajor
The neighboring, not-yet-built El Gallo 2 project also grew its resource sharply - Measured & Indicated silver up 20% to 63.9 million oz and gold up 215% to about 202,000 oz - as McEwen converted Inferred material ahead of updating the project's mine plan.
17 July 2013resource reserve update▲ GoodMajor
McEwen's El Gallo 1 mine in Mexico, which had just reached commercial production in January 2013, saw its gold resource grow 38% to about 691,500 ounces, and the company began a 50% mill expansion (to 4,500 tonnes/day, ~$5 million) meant to ramp output from 27,300 oz this year toward 75,000 oz by 2016.
15 May 2013resource reserve update▲ GoodMajor
The Los Azules resource grew again - Indicated copper up 17% to 5.4 billion lbs and Inferred up 32% to 14.3 billion lbs - capping the most successful drill season yet, with a new economic study due in the third quarter to evaluate higher throughput and producing cathode copper instead of concentrate.
28 Mar 2013drilling progress report▲ GoodMajor
New Los Azules drill results extended high-grade copper mineralization both along a new western trend and more than 300 meters deeper than previously tested, including 0.51% copper over 618.5 meters in one hole - results that will feed into a resource update due by the end of May.
6 Feb 2013resource reserve update▲ GoodMajor
A further Los Azules resource update pushed Inferred copper up another 29% to 13.95 billion lbs, though Indicated copper slipped slightly to 4.45 billion lbs as deeper drilling opened up a new parallel mineralized trend; an updated economic study was slated for later in 2013.
10 Sept 2012resource reserve update▲ GoodMajor
A feasibility study for Phase II of McEwen's El Gallo silver-gold project in Sinaloa, Mexico came back positive: about 5.2 million oz of silver and 6,100 oz of gold a year for the first six years, a 26% after-tax IRR at $25 silver, and roughly $178 million of initial capital needed.
