THE CRC LEME LEGACY -

A guide for mineral exploration through the regolith in the Cobar Region, Lachlan Orogen, New South Wales

The guide is designed to assist mineral explorers working in the regolith-dominated terrain of the Cobar region and surrounding areas of western NSW. This region is a major metallogenic province with a long history of metal production and remains highly prospective for deposits of copper, gold, silver, lead and zinc.

The guide provides a basic introduction to the regolith and landscape history of this area, as well as advice on appropriate exploration strategies and techniques for exploring through the different types of regolith cover. It is based on current knowledge (2008) and best practice, but it is not meant to be a fool-proof manual for exploration success.
