The Carahuacra Norte pit has been inactived since 2018. |
Summary:
In 2014, 2,866 meters were drilled in nine diamond-drill perforations from inside the mine aimed at intercepting the Mary Vein, to delineate new inferred resources with 70 x 70 meter grids at 200 meters below 1,070 level (3,960 masl). The boreholes also intercepted the Ramal Mary and Tensionales veins with positive results in terms of polymetallic mineralization, mainly zinc. The ore potential in Manto Principal has been confirmed with favorable results. Principal has been confirmed with favorable results.
Summary:
During 2015 the Carahuacra Norte open pit continued its exploitation activities, extracting a total tonnage of 394,500 DMT. In December 2015 the exploitation activities came to an end.

Summary:
The operation of the Victoria concentrator plant is automated, including Courier online analysis systems and a control system that regulates the ratio of water to ore during the milling process. It is worth highlighting that the Victoria concentrator plant can separate low-grade lead and copper concentrates by flotation.
At this plant, zinc recovery was 93.7%, lead recovery was 86.8%, while copper recovery was 34.1% and silver recovery was 83.5%.
