Hochschild delivers cost savings through installation of new power lines 
 
 
Hochschild Mining plc ("Hochschild") is pleased to announce that it has 
successfully completed the construction of new power lines at its operations in 
Peru and Argentina to ensure that each site has the most cost effective and 
reliable supply of energy. 
 
 
The installation of new power lines is just one of a number of projects which 
Hochschild is undertaking to maximize operational efficiency and reduce costs, 
supporting its target of reducing unit cost per tonne by 5% in 2009 compared to 
2008. 
 
 
In Peru, a new 22 kilometre replacement 66 kV power line has been installed at 
Arcata which has increased the available energy supply following the plant 
expansion undertaken in 2008. At Selene, where the ore from Pallancata is 
processed, a new 74 kilometre, 60 kV power line has been installed which is 
working in parallel with the existing 30 kV power line to provide energy to 
Selene and Pallancata. 
 
 
In Argentina, a new 130 kilometre, 132 kV power line and transformation 
station have been installed which connect the San José operation to the national 
grid, eliminating the need to use onsite generators as a primary source of 
energy. The new power line should cover any future capacity increase at the 
operation. 
 
 
Miguel Aramburú, Chief Executive Officer of Hochschild Mining plc, commented: 
 
 
"The installation of new power lines is just one of a number of projects which 
Hochschild is undertaking to maximize operational efficiency and is already 
delivering cost savings for our operations in Peru and Argentina. We remain on 
track to deliver our target of reducing unit cost per tonne by 5% in 2009 
compared to 2008".
