Modern mining geology

An overview of the modern mine geologists’ role, and a discussion of professional best practice and pitfalls to avoid.

Although mining has occurred for thousands of years, geology as a profession did not have wide recognition until the 1780s. Up until the 1920s geology tended to be an academic pursuit. The identification and discovery of mineral deposits was by professionals primarily trained as engineers or surveyors (Park, 1906).

As well as the need to find and mine ores more efficiently, the cause of mining geology was considerably advanced by litigation. In the USA, the ‘Right of Apex’ mineral laws meant that pegging the outcrop of a vein gave the leaseholder the rights to mine the down-dip extents of the vein. Geologists were needed to verify if veins found underground were the same as the vein exposed in outcrop or ‘apex’.  Details of these exploits are described by Sales (1964).
