Jacobs Engineering Group Inc. (NYSE:JEC) announced today that it received a
contract from Minera Chinalco Peru S.A. to perform a feasibility study for the

of Peru.

Officials did not disclose the contract value, but noted that the project is
expected to be executed out of Jacobs’ Lima, Peru office with assistance from
its Santiago, Chile and Tucson, Ariz., US offices.

Jacobs has been working on the Toromocho copper project since 2006. The mine
is located at an altitude of 14,700 to 16,400 feet. The current phase of
engineering, procurement and construction management is nearing completion.
Under the original design, the facility is capable of treating 117,200 tons of
ore per day and producing in excess of 210,000 tons of copper annually, plus
byproducts of silver and molybdenum.

Major equipment required for the proposed capacity expansion includes apron
feeders, a conveyor system for mill feed, a semi-autogenous grinding (SAG)
