Sedgman Metals Engineering is providing the detailed engineering and procurement (EP) services for the 2 Mt/a silver/gold flotation/CIL plant and associated infrastructure. The plant is expected to produce approximately 430 tonnes of silver and 130,000 ounces of gold per annum.

The project, located in the Sierra Madre Occidental Mountains, is especially challenging due to the nature of the region which has necessitated the mining of benches to accommodate the plant. Road access has also proved to be challenging with 200 km of mountain tracks being upgraded to a standard suitable for heavy equipment transport. Preliminary engineering commenced in September 2005 with environmental approval obtained and kickoff of detailed engineering in June 2006. The engineering phase of the project is now complete.
