Nevsun Targeting Second Quarter 2013 Start for Bisha Expansion
The bulk of the project capital cost for the Bisha expansion is going toward con-struction of a copper flotation concentrator and concentrate load-out facilities. The existing carbon-in-leach processing plant will be placed on care and maintenance in a condition that will allow it to be re-com-missioned if additional gold oxides are found at or near Bisha.
As of mid-June 2012, most of the major equipment, including all of the copper flota-tion cells, arrived at Bisha and was awaiting installation. The filter press frames, regrind mills, concentrate thickener, mill cyclones and regrind cyclones were in transit.
Foundations for the cells, racking, reagents storage, and workshop were nearing com-pletion, and assembly and installation of the plant equipment was expected to begin before the end of the month.
Nevsun has selected a Rotainer system for delivery of concentrate into bulk ship-ping carriers, using the existing Massawa container port on the Red Sea coast of Eritrea. Concentrate will be trucked in reusable intermodal containers from the Bisha mine site to the port and stacked at the existing container facility. Container trucking will be contracted, and no special-ized truck or trailer equipment is required. The copper concentrate containers will be discharged into bulk carriers using Rotainer’s “Lid-Lift” crane equipment. The capital cost of the Rotainer system and con-tainers is expected to be under $25 million.
