Caylloma Silver and Gold Mine

Caylloma Silver and Gold Mine

Callyoma is located approximately 225 kilometers northwest of Arequipa, Peru at an elevation of 4,500 meters above sea level. The mine, processing plant and related infrastructure are located in the Caylloma Mining District, 14 kilometers northwest of the town of Caylloma.

Fortuna purchased a 100% interest in the Caylloma Mine and related mining concessions in 2005. Following significant expansion and modernization of the mill, the mine resumed production in the final quarter of 2006.

The mill is currently operating at a rate of 1,300 tpd. Production is sourced primarily from the silver-polymetallic Animas vein (95%), with the balance from the Bateas vein.

Closure plan preparation

Cica Ingenieros Consultores

The components of the closure plan of mining environmental liabilities (MEL) are made up of underground workings comprising 15 mine entrances and a concentrator plant. There are also surface components which are 09 facilities for waste handling (08 waste deposits and 01 tailing dam).

The MEL closure plan includes current conditions within the project area considering physical, biological, social, economic and cultural environment. Respective closure activities, maintenance and post-closure monitoring as well as schedule and budget are also described.

According to directorial resolution Nº588-2014-MEM-DGAAM given on December 1st 2014, the closure plan of mining environmental liabilities was approved meeting the technical requirements for the Peruvian Ministry of Energy and Mines.

The modification of the EIA study considers within the area of influence direct and indirect the travel path of the new primary transmission line 15kV SE Caylloma - Bateas (Power House). It considers, according to the norm of imposing servitude, a distance of 6m wide servitude for all building and operating facilities areas.

The EIA contains socio-environmental baseline assessment of environmental impacts during the construction, operation and closure, the respective environmental management plan, conceptual closure plan, cost analysis, community relations plan and monitoring program.

According to directorial resolution Nº459-2013-MEM-AAM given on December 2nd 2013, Peruvian Ministry of Energy and Mines approved the Amendment of EIA for new 15kV transmission line substation Caylloma - Bateas.
