Defining a Drill Grid

  • Friedrich-Wilhelm Wellmer

Abstract

During exploration, one usually drills targets that are defined by geochemical or geophysical anomalies, or by a geological concept, although in mineral exploration it is more usual to drill geochemical and geophysical anomalies. However, in exceptional circumstances, a blind target that has been defined by a geological concept will be tested by drilling.
