Deposit Type

  • Vein / narrow vein


Summary:

The Alpamarca-Rio Pallanga project is a deposit of lead, zinc, silver and copper veins. It is located 4,700 meters above sea level in the Santa Bárbara district of Carhuacayan, Yauli Province, Junin Region. Alpamarca Rio Pallanga is a polymetallic deposit of lead, zinc, silver and copper veins. The project consists of 2,100 hectares of concessions in an area with significant geological potential.

Ten kilometers from Alpamarca is the old Rio Pallanga mine, a deposit with significant potential at depth and in the lateral extensions of the vein in the explored area. The Rio Pallanga resources, which contain high grades of silver, will support ongoing operations at Alpamarca and provide a solid basis for development of projects at Colquihuarmi and Carhuacayan, located 14 and 25 kilometers to the southwest, respectively.


Mining Methods

  • Longhole stoping


Summary:

Operations were carried out within the Pallanga 3 concession and continued with preparation, development and production of the Ramal 1 and San José veins. Long-hole drilling was used in narrow veins, where very good results were obtained in controlling mining widths. In addition, there was excellent control of the supports using bolts and mesh. Finally, the auxiliary drainage and ventilation systems for deepening the mine were completed.

The progress and production of the underground mine were temporarily suspended since December 2015.
