The need for interdisciplinary research on resource appraisal techniques was recognized by Lasky, more than 30yr ago. His efforts to devise an appraisal technique that incorporated many attributes of mineral resources resulted in a cumulative tonnage-grade relationship that has since been referred to as 'the arithmetic-geometric (A/G) ratio' or 'Lasky's law'. A review of subsequent studies indicates that his work has at times been misinterpreted. Lasky's relationship is shown to be consistent with studies of the correlation between average grades and tonnages of mineralized material in ore deposits. The projection of Lasky's analysis to lower grades is limited because the mathematical formulation predicts physically impossible situations below some limiting grade. -Author
