Alliance Mining Commodities Limited is developing its flagship project, the Koumbia Bauxite Project, in the West African country of Guinea, about 160 kilometers northwest of Conakry, the country’s capital. Guinea contains approximately 40 percent of the world’s identified bauxite resources; it is the world’s largest bauxite provider.

Alliance Mining envisions that the project will support a long-life operation with the potential to produce more than 10 million tons per annum (Mtpa) for more than 25 years. Alliance Mining has reported that Koumbia is a world-class deposit estimated to contain 2.2 billion tonnes, or about 2 percent of the world’s bauxite.

Tetra Tech Proteus completed the definitive feasibility study for the development of the 10-Mtpa bauxite project. The study investigated the mine, rail, port, and central facilities for the project, including mining facilities, train loading system, and rail and bridges to the port loading facilities, as well as administration and maintenance facilities.

Alliance Mining selected Tetra Tech to undertake the feasibility study and subsequent work packages because of its recognized capability to leverage off its global offices in Perth (project management and engineering), Beijing (Asian expediting and logistics), London (European expediting and logistics), and Guinea (construction management and commissioning).

Tetra Tech was also able to demonstrate its industry-recognized expertise in the design of large-scale processing and infrastructure projects.
