An Update
Description:... Dramatic changes have occurred in the metal mining sector over the last 25 years, some of which were reviewed in a Ministry study which investigated the impact of rising indirect labour costs and a shift toward white collar workers on the productivity performance of the metal mining industry from 1960-77. This study updates this earlier work and covers 1977 to the present, reviewing the earlier study, presenting issues to be studied, and covering the demand for metals, productivity changes, production costs, labour costs, and mining benefit costs in the United States and Canada.
