Equus Mining holds rights to mining and exploration concessions totaling 2,260 hectares which comprise the Los Domos Low to Intermediate Sulphidation style epithermal gold-silver-base metal project, located approximately 15km south of the township of Chile Chico in Chile’s XI Region (Figure 1).
Chile Chico has an approximate population of 4,500 habitants and historically has acted as base for the workforce of approximately 450 people directly employed in previous mining activities, which have been an important contributor to the local economy.
The Los Domos Project is located approximately 20km to the southeast of Mandalay Resource´s Cerro Bayo mine and flotation processing plant (500ktpa), which has been under care and maintenance since a mine flooding event in June 2017. This mine has produced approximately 1.7 Moz Au equivalent since initiation in 1996, in which mineral concentrate was trucked approximately 250km via ferry between the nearby township of Chile Chico to Puerto Ibanez and then by road to the Pacific coast port infrastructure of Puerto Aysen.

The Los Domos Project is situated in the interpreted northwest extension of the world class Deseado Massif mineral province, where it extends into southern Chile, which currently hosts 7 operating gold-silver mines. This interpretation is based on comparable host rocks, styles and Upper Jurassic ages of mineralization, the latter as reported from south-eastern portions of the Cerro Bayo mine district, to several of the deposits that occur in the western portion of the Massif in Argentina e.g. San Jose Mine.
Several of the more notable Low to Intermediate Sulphidation epithermal style gold-silver projects in the Deseado Massif include: Cerro Negro (7.4 Moz Au equivalent), San Jose (2.9 Moz Au equivalent) and Cerro Moro (2.3 Moz Au equivalent).
Prior to Equus initiating exploration activities throughout the Los Domos area in 2016, previous exploration, limited to reconnaissance mapping and surface geochemical sampling, was predominantly carried out by Chilean subsidiaries of Chevron Minerals, Freeport McMoran and Coeur Mining between 1985 – 2005.
