SnapshotThe El Gallo mine operated from September 2012 to June 2018, when active mining was ceased. Residual leaching production and ongoing closure and reclamation activities continued through 2025.

The Fenix Project is a proposed redevelopment plan for the El Gallo Complex. The Fenix Project envisions a two-phase development process: Phase 1 involves the reprocessing of material from the leach pad at the existing El Gallo mine, referred to as HLM. Phase 2 encompasses the processing of open-pit silver mineralization from the nearby El Gallo Silver deposit, utilizing the existing processing plant.

As of the end of 2025, most of the equipment necessary for the plant has been mobilized to the project site to undergo a comprehensive refurbishment program.

Dec. 16, 2025, McEwen announced that the extension of its Environmental Impact Assessment for the El Gallo Mine has been granted by the Mexican government. This approval is a critical step to begin Phase 1 Mill Construction.

Summary:

Gold mineralization in the El Gallo 1 mine area occurs in six deposits along two distinct structural trends, northwest and northeast. A northwest trending structural zone hosts the Samaniego and San Rafael deposits. San Dimas also is hosted by a northwest-striking structure. The second structural trend is northeast-striking and includes the Sagrado Corazón, Lupita and Central deposits. Along these structural trends the mineralization is located within numerous sub-structures that may be parallel, oblique or even perpendicular to the principal trends. Mineralization among the various deposits of the El Gallo 1 area is generally similar, with the individual structural zones consisting of quartz stockwork, breccia, and local quartz vein mineralization occurring within propylitically altered andesitic volcanic rocks. The Samaniego, San Rafael, Lupita, Sagrado Corazon and Central deposits are characterized by gold accompanied by iron oxide and variable copper; the San Dimas deposit is polymetallic containing gold, silver, copper, lead and zinc.
