This report presents the development of economic indices for the United Kingdom for the period from 1970 through 1981. The work was done through the Bureau of Mines minerals availability program under contract. The contract calls for the development of 12 index time series describing factor input costs in the mining sector of 95 countries. The index time series describe the costs of (1) mining wages, (2) construction wages, (3) equipment and repair parts, (4) bits and related steel, (5) timber and lumber, (6) fuel, (7) powder and blasting agents, (8) tires, (9) construction materials, (10) industrial materials, (11) transportation, and (12) electrical power. The indices were developed primarily for use in the Bureau's minerals availability program in assessing the worldwide availability of nonfuel minerals and, when combined with weight factors being developed by Bureau personnel, will be used to perform instantaneous updates of all costs relating to the mining industry.
