SAN DIMAS

LOCATION

The San Dimas mines are located on the border of the States of Sinaloa and Durango, some 125 kilometres northeast of Mazatlan in central west Mexico.  The project site is accessed by aircraft in a 45 minute flight from either Mazatlan or Durango, or by road through a ten hour drive from the city of Durango. Most of the personnel and light supplies for the San Dimas mines arrive on regular flights from Mazatlan and Durango.  Heavy equipment and supplies are brought in by road from Durango.

Tayoltita is the most important population centre in the area with approximately 8,000 inhabitants, including mining company personnel. The population outside the mining town is sparse.

Water for the mining operations is obtained from wells and from the Piaxtla River. Water is also supplied by Goldcorp to the town of Tayoltita from an underground thermal spring at the Santa Rita mine.

Electrical power is obtained from a combination of Goldcorp owned power systems and the Federal Power Commission’s supply system. Goldcorp operates hydroelectric and back-up diesel generators which are connected to the Federal Power Commission system.

The San Dimas region is mountainous. Elevations range from 2,400 metres on the high peaks to 400 metres in the valley floor of the Piaxtla River. Pine, juniper and scattered oak trees grow on the higher ridges while the lower slopes and valleys are covered with thick brush, cactus and grasses. Mining, subsistence farming, ranching and timber cutting are the predominant activities in the region.

The Nukay mill is located approximately 2 kilometres from the town of Mezcala, in the municipality of Eduardo Neri, in the state of Guerrero, Mexico, approximately 230 kilometres south of Mexico City and 180 kilometres north of Acapulco.  The closest cities are Iguala, located about 40 kilometres north of the plant, and Chilpancingo de los Bravos, the state capital of Guerrero, located about 40 kilometres south of the plant.

Access to the operations is through the nearby village of Mezcala.  From Mexico City, Mezcala can be reached from highway 95, a major, paved route between Mexico City and Acapulco. From Mezcala, access to the Nukay mine is along 12 kilometres of winding dirt roads
