At the El Gallo Project, mining and crushing activities ceased during the second quarter of 2018, with production activities since that time limited to residual leaching.

Residual leaching continued in 2021 and continues into 2022.

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.


Mining Methods


Summary:

Originally known as the Magistral mine, the El Gallo Project was an open-pit gold mine and heap leach operation that we operated from September 2012 to June 2018, when we ceased active mining. Present activities are limited to residual leaching production that is expected to continue into 2022, as well as closure and reclamation activities.
