Sometime, mining companies during the first months of operation employ this method to study zones that were not studied well during the exploration program. Results are different. For example, by employing a core drilling program the average gold content was 5 g/t. however, the second method on the same place gave higher values, 10 g/t. This situation creates doubt and conflict between the ...

Definition of selective mining - MindatTraduire cette page

Compare with: bulk mining ii. The object of selective mining is to obtain a relatively high-grade mine product; this usually entails the use of a much more expensive stoping system and high exploration and development costs in searching for and developing the separate bunches, stringers, lenses, and bands of ore. In general, selective methods are applicable where the valuable sections of the ...
