The Bonasika bauxite project will utilise conventional open-pit mining method to recover ore. Mining equipment will include 40t haul trucks, dozers and 3.2m excavators.This move to open-pit mining has resulted in a considerable increase in the scale of production. The current optimal size is about ten million tons each of iron ore and bauxite, and five million tons of copper and uranium per annum. As a result the unit costs of ore extraction have decreased, thus reducing the minimum efficiency level of the.

It is a trucks and excavators loading operation in which 20-30 tons capacity of trucks are utilized to haul ores from mining pit to beneficiation plant.Only the 54.1 M$ will have to be financed to put the mine into production equipment renewals will be financed from cash flow generated by the project. Operating costs are estimated at $4.5 per tonne of bauxite during Phase I (the first six years) rising to $4.7 t in phase two and to $5.2 in phase three because of the increased stripping ratio.
