High-Grading In Metalliferous Ore Bodies - The Economist’S Persperctive


  • Glenn Jenkins

    () (Queen's University, Kingston, On, Canada)



As economists with some experience in mineral economics and the analysis of mining tax policy in several countries, it has been with some interest that we have followed the recent exchange between Thomas and Alduck in Mining Magazine regarding the economic effects of "high-grading". It is our purpose in this paper to contribute an economist’s perspective to the problem of grade management, and to comment upon several points of the Thomas and Walduck contributions which we believe to be unclear or erroneous.
