18 INFRASTRUCTURE
18.1 Site Roads
18.1.1 Site Access Road
Arica or Antofagasta ports in Chile are the preferred locations to receive equipment imported
from outside South America and from there by road to Uyuni and Pulacayo.
The road from Potosi to Uyuni was paved recently during 2012 and will be used for local
supplies coming from that area of the country. Uyuni and Pulacayo are connected by
unpaved, good quality road.
Equipment coming from Brazil will arrive in Puerto Suarez and be transported to the mine
through Santa Cruz (975 km), then to Oruro (471 km) and from Oruro to Pulacayo (210 km).
The same road from Santa Cruz will be used to bring equipment, materials and supplies
from the east of the country.
The road coming from the capital city, La Paz, passing through Oruro and Santiago de Huari
is being improved by the government and is the main route to transport goods from the
capital and Oruro, to Uyuni, Pulacayo and Potosi.
18.1.2 Plant Site Roads
Apogee has developed site roads from the mine adit (San León Adit) to the primary crusher,
access from the plant to the Tailing Storage Facility (TSF) and Fresh/Process Water System
and access to the various components of the processing plant.
This access will be surfaced with granular materials. Drainage ditches and culverts will be
placed in accordance with the site drainage requirements. Access road from Pulacayo to the
camp site has not been developed as yet.
18.2 Power Supply
A significant operating cost for the Pulacayo Project will be the power required to run the
operations. Permanent, on-site diesel generation is not an option due to diesel cost in Bolivia
and availability.
EPCM Consultants, Bolivian local consultant was appointed to develop the power supply
assessment for the mining and process operations. The most suitable option to get power to
the Pulacayo project is the construction of a 115 kV power line, connecting to the existing
Punutuma-Atocha 115 kV line, implementing a switching substation in Tazna town, 61 km
from Pulacayo and a transformer substation close to the operation to get 25 kV. The route
for the line is defined. The definition of the route allowed the company to start the permitting
