Aspects of Mineral Exploration Thinking (Society of Economic Geologists article, January 2022)
![]()
Conventional wisdom holds that grade beats everything. The author disagrees with that view. The objective of mineral exploration is to find a highly profitable ore deposit, regardless of the grade. That single thought should be constantly on the mind of every explorationist. Low-grade deposits can be very profitable, and some high-grade deposits are unprofitable.
The author ranks continuity of grade as the most important of the technical aspects required for a profitable mine, although it is not the only important thing. Continuity of grade is just one of many important aspects of a mineral deposit including access, infrastructure, jurisdiction, permits, reserve estimates, mining and metallurgical methods, cost estimates, and social and environmental setting, and any one of these aspects can doom a mine development.
