AECOM was awarded the site-development and contract-mining contract in 2004 for the new Metallica Resources’ gold/silver mine development in central Mexico. The $105 million project will include earthworks for the processing area and mine.

The San Pedro gold/silver operation will be a conventional open pit mine producing over 755,000 ounces of gold and 17.3 million ounces of silver over the mine’s 8-year life.
