Quellaveco Copper Mine

Quellaveco Copper Mine

A copper mine project for which feasibility studies are expected to be completed in 2015. Anglo American Plc has 81.9% interest in the Quellaveco project through its subsidiary Anglo American Quellaveco SA, the company in charge of its development.

The project is located in the districts of Torata and Samegua province of Mariscal Nieto, Moquegua Peru and considers the exploitation of a copper open pit mine at a rate of 85,000 tonnes per day (tpd). It includes a copper production facility and port expansion.

Copper ore reserves of the project as of Dec 2014 stand at 1,332 Mt out of which 71.4% have been proved. With a lifetime of 29 years and %TCu grade at 0.58, Quellaveco positions itself as one of the biggest copper projects in Peru.

The third modification of the EIA is carried out in order to optimise the design and operation of Viscachas dam, it proposes the growth as well as its operation.

With respect to the dam growth, dike shall increase in 4.5m bringing about a total height of 35m achieving an increment of storage capacity from 28.5 to 60 million cubic meters. Dam operation includes the intake and discharge of Chincune river entire flow.

According to directorial resolution Nº377-2012-MEM/AAM given on November 14th 2012, the thrid modification of Quellaveco project EIA was approved meeting the technical requirements for the Peruvian Ministry of Energy and Mines and the environmental local regulations.

Drilling tools

DSI PERU S.A.C.

Tunnel drilling consisting of a main 7.8km long water tunnel with a 1.2km long access tunnel and a 4km long conveyor tunnel.

Slope stabilization in the portal areas has been accomplished using the DYWI® Drill Hollow Bar System, mesh, and shotcrete. For slope stabilization in this area, DSI Peru supplied a total of 508 3m long diameter T76 DYWI® Drill Hollow Bars as well as 461 4m long diameter T76 DYWI® Drill Hollow Bars. In addition, DSI supplied 875 couplers and 513 Ø 200mm button drill bits.

The main method used for the first part of the tunnel excavation was drill and blast. The ground support scheme consists of lattice girders, mesh, rock bolts, and reinforced shotcrete. For the second part of the tunnel that will be built, DSI Peru will presumably also supply forepoling systems that are required for driving through the expected fault zones.

The second EIA amendment suggest modify the transportation of concentrate, port facilities and transmission line.

The transportation of concentrate shall be from concentrator plant located in Papajune to the new facilities to be built in Enersur port using a 165.2km journey. Port facilities includes the construction of facilities for storage and shipping within Enersur area. A transmission line of 220Kv and 37Km shall supply power from Moquegua sub-station.

According to directorial resolution Nº319-2010-MEM/AAM given on October 5th 2010, the second modification of Quellaveco project EIA was approved meeting the technical requirements for the Peruvian Ministry of Energy and Mines and the environmental local regulations.

The changes proposed in the EIA modification are related to water supply as well as operations and propose the increment of concentrator plant processing capacity from 64,000 to 85,000 tonnes per day (tpd). With regards to water supply, these resource will be captured from from the river Titire (up to 700 l/s) as well as though a reservoir built on the river Viscachaz.

Ore reserves of copper and molybdenum are 938 million tonnes, which shall be exploited in 32 years considering the new processing capacity. It is proposed to locate the concentrator plant in Quebrada Papajune due to lack of space at the Quebrada Quellaveco .

According to directorial resolution Nº140-2010-MEM/AAM given on April 23th 2010, the first modification of Quellaveco project EIA was approved meeting the technical requirements for the Peruvian Ministry of Energy and Mines and the environmental local regulations.
