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 reduction it had flagged as likely back in Q1 2020: Probable Reserves are now 302,000 oz, down 30% from the 430,000 oz estimated when mining started in 2019, driven by revised geology, metallurgy and drilling data; after-tax NPV is now $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's $15 million 2018 Black Fox exploration program hit a record pace (129,000 ft drilled in Q2 alone) with encouraging results at the Stock East, Froome and Gibson targets, and the Black Fox Mine's own resource was upgraded, eliminating the Inferred category entirely in favor of Indicated ounces.
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.
