The Holguinera deposit is made up of the surface of a thick soil that developed from the decomposition of the residual material from the weathering of porphyry diorite. The rock is strongly propylitized, silicified, and limonited, and exhibits abundant sulfide mineralization accompanied by gold. In general, its contact with serpentinized harzburgite is usually very breccious and mineralized. The ores of the Holguinera deposit are mainly sulfide, sulfide–polymetallic, sulfide with iron, pyrite, and chromitic, located in veins or a dispersed form. Gold mineralization achieves grades ranging from 0.13 to 19.9 g/t Au. the gold ore resources in the Holguinera deposit to be around 1,062,000 tons and about 1494 kg of gold metal, with a content of 1.0–4 g/t Au.
