Bob Adamson commenced consulting in economic geology in 1993 following 25 years in technical and management positions with the CRA, Newmont, BP Minerals and Cluff groups.
He is experienced in the exploration and mining of base metal and gold deposits throughout Australia, New Zealand, southern and eastern Africa, northern Asia and northern Canada and has had significant involvement in the discovery and development of gold and base metal mines in several of these regions. He is also experienced in diamond and semi-precious stone exploration (especially eastern Australia).

Bob specialises in exploration appraisals and project management with emphasis on best-practice drilling and sampling procedures, the recording of data and the development of practical geological models of mineral deposits.
