Sommaire: Many porphyry copper deposits of the Kerman copper province in central Iran are associated with a consistent structurally controlled main drainage pattern, which is shown in this paper to be a useful regional prospecting tool in the search for new deposits. The main drainage trends also generally allow the distiction of high-grade (>0.2% Cu) from lowgrade (<0.2% Cu) deposits. Topographic maps
1:50 000 or geologic maps 1:100 000 have been found suitable for identification of promising drainages.

Sommaire: Drawpoint control is critical in determining the cutoff point for load-haul-dump mucking operations to minimize dilution. It is also necessary to ensure even mucking distribution and to prevent possible hang-up of material within a stope. A prototype production monitoring and reporting system has been developed for load-haul-dump operations in underground mines. The system generates accurate
and timely information regarding mucked tonnages and drawpoint and ore/waste pass utilization. The...
