ECONOMIC EVALUATION OF BULGHAH MINE PROJECT GOLD DEPOSIT IN SAUDI ARABIA

摘要

This project is an outcome of the postgraduate diploma course on Project evaluation, CESPROMIN, for the year 2008-09, one of the CESMAT cycles in the frame of MINES ParisTech. The objective of this project was to understand the methods of Economic Evaluation of a Mining Project, which includes the selection of Mining method & Reserve estimation & Financial Assessment. To present my understanding on Mine Economics & impact of different parameters of Project Finance, as a part of Final report for the CESPROMIN Course, I have tried to do the Economic Evaluation of Bulghah North Gold Mine, which is still in conceptual stage. From the limited data available, I with the help of Dr. Isabelle Thenevin tried to run Whittle software to optimize the Pit but due to improper block model I could not succeed in optimizing the Pit. The reason for that is the project is still geological evaluation stage, under the consultant engaged for the purpose. The Project evaluation has been done in three options. Option I &II with stripping ratio 1.4 t/ m3 and option III with stripping ratio 1.7t/m3 at Cut-off grade 0.3 g/t. To improvement the final product recovery of the fresh ore I suggested to up date the plant by adding new tertiary crusher parallel with old tertiary crusher to reduce the particle size.
