At the El Gallo mine in Sinaloa, Mexico, mining and crushing activities ceased during the second quarter of 2018, with production activities since that time limited to residual leaching up to the third quarter of 2022.
Activities at the El Gallo mine in 2022 were limited to residual leaching as part of closure and reclamation plans.
The McEwen is currently reviewing reprocessing heap leach material at the El Gallo mine (“HLM”) as well as new silver processing operations (“El Gallo Silver”) in the immediate vicinity as part of its Fenix Project. |

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.
Summary:
The El Gallo mine, originally known as the Magistral mine. The El Gallo mine was an open pit gold mine and heap leach operation that was operated from September 2012 to June 2018, when was ceased active mining. Residual leaching production and ongoing closure and reclamation activities continued through 2022.
