WORK DONE

ESP – 01

 

Cu (Ag)

An old underground mine located 800 km N of Santiago city and 41 km SE of Copiapo city.

Located in an active mining sector, with ore processing plants nearby (Elisa de Bordos, ENAMI, others) for the sale of ROM or concentrate.

It has access to infrastructure, energy and the supply chain.

There are ten tenements covering about 2,800 ha.

The deposit is located in the fault “Elisa de Bordos”, a structure being exploited by several mines, between Elisa de Bordos and Cerro Blanco. This fault contacts the Cerrillos (Middle Cretaceous) and Hornitos (Upper Cretaceous) formations. The ore is found in a 0.5–3.0 m wide manto, with NE orientation, and inclined 30–40° to the SE. Mineralization is located between the upper calcareous sediments, lower tuffs and pyroclastic rocks, mainly consisting in chalcocite and, secondarily, bornite.

The mine has been exploited since more than one century ago, so it counts with several geology and exploration studies made by authors such as Walther Eberle (1998), Mayer & Fontbote, and Harry Floyd (2006).

The Chilean company Pucobre conducted geophysics and a drilling campaign in the period 2004–2005.

A geology study was made in November 2014 by an independent consultant.

Fresnillo PLC took 40 samples and the lab results showed good results for copper and silver, where 25% of samples gave 1.0–5.5% Cu and 120–520 g/t Ag.

The mine was exploited again during 2015 and the ore was sold to the processing plant of ENAMI Matta. Exploitation was suspended due to a drop in metal pricing.

Located 25 km SE of Ovalle city and 10 km E of Punitaqui town, at an altitude of 900 masl.

Mining property covers 100 ha, but other properties with excellent mining potential could be incorporated in the near future. These properties are being targeted.

Project is located in an attractive zone in terms of exploration potential, and also at the vicinity of ore processing plants and purchasing centers to get mining supplies.

It is highly feasible to start a mining operation of 5,000 tpm in the near term.

Au-Ag-Cu vein type mineralization hosted by Lower Cretaceous meta andesites and granitic rocks of dioritic and granodioritic compositions. The alteration halo in the Au-Ag-Cu veins in San Lorenzo presents a widespread strong argillization bordering veins, consisting mainly of kaolinite with minor proportions of montmorillonite and adularia-sericite assemblage, and restricted root zones of silicified envelopes. Chloritic or propylitic alteration represent the peripheral alteration.

Mineralogy reflects a distal epithermal halo, from similar enriched proximal ores like in Punitaqui district, consisting of quartz, specularite, hematite, pyrite, chalcopyrite, calcite, gold, silver and magnetite.

Surface mapping, sampling and chemical analysis.

Geochemical results on San Lorenzo veins indicate important anomalies of Au (up to 1.03 ppm), Ag (up to 11 ppm), Cu (up to 0.57%),  Mn (up to 4830 ppm), V (up to 1102 ppm), As (up to 482 ppm), Sb (up to 3600 ppm) and Fe (4.99-42.76%).

Au – Ag – Cu

Located 115 km SE of Copiapo city and with a good year round access via gravel road. Some difficulties may be expected during June and July due to snow fall.

The property covers 2,200 ha.

Project has a magnificent strategic location, immediately SW of Cerro Casale.

One main target is located at the SW slope of the Cadillal volcanic field, known as the Aguas Blancas Tertiary volcanic system belonging to the Maricunga gold metallogenic belt in the high Chilean Andes.

The gold mineralisation is genetically linked to the sub circular collapse structure called “embryonic caldera” corresponding to an epithermal event coeval with the high-sulphidation Au-Cu Cerro Casale deposits, located at the central zone of the same hydrothermal-volcanic system.

Several mining workings evidence the presence of stockworks, hydrothermal breccias and veins associated to argillic and quartz-alunite alteration. Preliminary sampling on these area show grades up to 2 g/t Au included in hydrothermal breccias. Exploration results and its coeval genesis with Cerro Casale deposit suggests that the system may have been aged enough to concentrate fluids and mineralization into a high-grade core.
