Department of Energy. Performance, total system effects, life-cycle costs, uncertainty, and environmental risk are all considered in the methodology to compare new technologies with existing or base-line technologies. An example of performance characterization is given in the paper. Sources of data for cost estimates and technology characterizations also appear in the paper. 1The authors gratefully aclmowledge the suppon provided for this work from the U.S. DepIIment of Energy under Technical Task Plan AL 2202-R.

Its data gathering and disseminating activities include: administration of technical assistance projects in developing countries, publication, in co-operation with the OECD's Nuclear Energy Agency, of 'Uranium Resources, Production and Demand', sponsorship of symposia on uranium resources and development, and participation in the International Uranium Resources Evaluation Project.

The time of primary mineralization is the oldest reported for Proterozoic unconformityrelated uranium deposits in the Athabasca basin. Data obtained in this study show that lead loss (or uranium gain) has occurred in highgrade rocks and that lead gain (or uranium loss) has occurred in low-grade rocks. Lead loss rather than uranium gain in high-grade ore is suggested by the petrologic work of Cumming and Rimsaite and the presence of excess radiogenic lead in the overlying sandstone documented by Curtis and Gancarz. Some of the results obtained in this study provide evidence of preferential movement of /sup 238/U intermediate daughters out of uranium minerals and into the matrix.

This study provides a methodology for applying benefit-cost analysis to mineral resource assessment programs, both to determine the cost effectiveness of resource assessments and to ascertain future
