15 Minera T ayahua Project: Scoping study , Mexico. Scope: Completion of a feasibility study covering aspects such as mining, geology , estimation of resources and geotechnical model, as well as environmental issues and hydrogeology in order to select the mining method and underground operation design (1 0,000 tpd). Outcome: Selected an underground mine design with a high productivity and extraction rate at a preliminary level for the demonstrated and potential geological resources of the skarn-type deposit. The project’ s business potential was identified, giving the client a strong technical base on which to base future decisions. A-Cap R esources Project: Letlhakane uranium project, Botswana. Scope: Scoping study of the Letlhakane project located in east- central Botswana. Outcome: The scope of work for the study included mining optimisation, evaluating the mineralogy and metallurgy , evaluation of water supply potential, the project environmental requirement, and then selecting a process option. Capital and operating cost estimates were developed for four scenarios. Confdential Client Project: Gold project, eastern Senegal. Scope: Pre-feasibility study (PFS) of a multiple deposit gold project involving a team of SRK and subconsultants. Conduct the studies and oversee all technical aspects of the project from exploration targeting through to mine closure. Outcome: Conducted a PFS within a very restrictive timeline. Managed data collection to get the most data possible from each part of the exploration program and kept multiple elements of the project progressing at the same time. The solutions met the needs of the client and local community . K atang a Mining Limited Project: Kolwezi, Democratic Republic of Congo. Scope: T o complete a feasibility study and independent technical report (ITR) on the material assets, which included four open pit and one underground copper/ cobalt mine, two existing processing plants and the development of a new SX/EW refinery and plant. Outcome: Both studies were published in April 2009. Underground design for a copper mine in Mexico
