SHORT COURSE

EPITHERMAL Au-Ag and PORPHYRY Cu-Au EXPLORATION

by Greg Corbett

with help from Stuart Hayward

Greg Corbett teaching

 

Two days of powerpoint lectures focus upon mineral exploration for epithermal and porphyry ore deposits derived from Dr Corbett’s 40 years field experience, and draws on earlier short courses provided with the late Terry Leach from the early 1990’s. Exploration and mining examples from over 40 countries are used to delineate the characteristics of different epithermal and porphyry ore types, and controls to mineralisation, using tools such as alteration, structure and breccias. The exploration implications are considered throughout and a final section considers geological features recognised in exploration marginal to ore bodies.

The new colour course manual in preparation with over 1000 rock photos represents a significant update since Corbett and Leach, 1998, Economic Geology Special publication 6. An exploration exercise is provided at the beginning and a possible solution at the end.

On the third day we bus to the NSW Dept. Mineral Resources facility at Londonderry to view porphyry and epithermal alteration and mineralisation in drill core from NSW mines and exploration projects as well as Greg’s set of specimens. Stuart Hayward, an explorationist with over 30 years porphyry and epithermal experience, will assist with this practical exercise. This display is designed to improve participants mineral identification skills and illustrate some important styles of alteration and mineralisation.
