The Santa Barbara Project is located in the Cordillera del Condor within the Zamora Copper-Gold Belt and hosts a gold-copper porphyry deposit. The most extensive rock unit at Santa Barbara is a fine-grained basaltic andesite volcanic - the same host rock as Lundin Gold's Fruta del Norte Mine - overlain by a sedimentary sequence of conglomerate, quartz sandstone, limestone, and locally garnet skarn. The volcanic and sedimentary units have been intruded by a swarm of northwest-trending diorite porphyry dykes ranging from 2 to 30 m in width, as well as a larger diorite porphyry stock in the northwestern portion of the deposit area.

Gold-copper mineralization is hosted primarily within the basaltic andesite volcanic unit and the diorite dykes, with the highest grades developed in the basaltic andesite in proximity to the diorite porphyry dykes. Mineralization is associated with a stockwork of quartz veins and potassic alteration consisting of secondary biotite and K-feldspar. High gold grades coincide with B-type quartz veins containing chalcopyrite, surrounded by biotite alteration and disseminated pyrite.

Santa Barbara exhibits the classic characteristics of Andean porphyry systems, including a central potassic core grading outward into phyllic, argillic, and propylitic alteration zones, and metal zonation from a chalcopyrite-bornite core transitioning outward to chalcopyrite-pyrite and pyrite-dominated zones. Key geological controls on mineralization include igneous contacts, cupolas, and the uppermost bifurcating portions of stocks and dyke swarms.

The mineralized zone defined to date extends over 1.2 km north-south, 600 m east-west, and to a depth of at least 900 m, and remains open along strike and at depth.
