Cerro Verde Expansion Beginnings

In 2010, Cerro Verde S.A.A. initiated a feasibility study to evaluate the possibility of expanding its Production Unit according to its large reserve of sulphides and oxides, by means of the construction of a second concentrator (C2) with:  a designed capacity of 240,000 MT/day  a leaching platform (PAD1, Phase III) with a capacity of 100,000 MT/day  mine development  a series of similar auxiliary and/or complementary facilities  the relocation and/or modification of various existing infrastructure


Cerro Verde Mine Operations 2016 Mined Material  630,000 MT/day (New Mined)  730,000 MT/day (Total Material Moved)

2016 Ore  360,000 MT/day Sulfide Ore  40,000 MT/day Crushed Leach Ore  40,000 MT/day ROM Ore

Average Grade of Mined Ore  0.387% CuT (3.874 Kg. Cu/MT)

 This includes primary sulphides (high, low grade) and leachable (high, low grade)

Water – Our Priority  Arequipa is located in a desert (Atacama desert)  The Peruvian government, authorities of Arequipa, and Cerro Verde worked together to plan and ensure the hydric resource for future generations - Collect water in Arequipa´s highlands with regulated dam system



Build a potable water treatment plant, which is one of the most modern in South America (PWTP II) -

It benefits 300,000 people currently and could benefit 750,000 in the future


Investment of US$120 million

Upgrade the potable and sewage water network in order to assure the water resource can reach homes -


Investment of US$40 million

Decontaminate the Chili River with a wastewater treatment plant


Waste Water Treatment Plant

The Chili River is key for life in Arequipa

The Chili River is the most important water source in Arerquipa; it is the key factor for economic activities such as agriculture, commerce, tourism and mining

It was used to receive all waste water produced in the city

SEDAPAR and Cerro Verde worked together to improve the quality of the Chili River through the construction of a wastewater treatment plant (WWTP)

The WWTP was financed totally by Cerro Verde

Operation and maintenance to be the responsibility of Cerro Verde for a minimum of the first two years

Investment to construct the WWTP was approximately US$500 million. 18

Enlozada WWTP A Win-Win Project

 

In exchange for financing the WWTP, Cerro Verde uses up to 1 m3/sec of treated water for the expansion of its operations The rest of the treated water is returned to the Chili River The WWTP benefits all of Arequipa: - Health – clean water that meets national and international standards - Agriculture – fresh water for irrigation - Tourism – quality recreational areas are being rejuvenated - Environment – positive impact on flora and fauna - Great sustainable development project that completes the virtuous circle of water

Great example of cooperation and joint team work between authorities and private companies 19

Transporting Concentrate to Matarani Port  Transport of sealed 15 metric ton containers

 Transport in trucks from CV to La Joya transfer station, approx. 52 km  Transport in train from La Joya to Matarani, approx. 55 km

Concentrate Transport at Port

Estimated 2016 Production Copper in Concentrates 1.04 billion lbs Cu in 2.0 million metric tons of copper concentrate

Copper Cathodes 110 million lbs Cu

Molybdenum in Concentrates 21 million lbs Mo in 17,500 metric tons of concentrate

Sustainable Development At Cerro Verde, we contribute to the sustainable development of Arequipa, through the integration of economic growth, environmental protection, social progress and the effective governance of our region.
