Supply Analysis Model (Sam): A Minerals Availability System Methodology.
MISSING :45 pages
Growing domestic and global demands for mineral resources have established an imperative need for developing comprehensive, versatile mineral supply analysis evaluation tools. The minerals availability system (mas) of the Bureau of Mines is meeting this need with its computerized supply analysis model (sam). This paper describes the sam system and the quantitative methods used by the mas for mineral supply analyses. The mas evaluating process consists of deposit identification, tonnage and grade determinations, engineering and cost evaluations, financial analyses, and supply curve generation. Mas has developed this computerized system primarily to facilitate the maintenance of data information for the constructing of commodity supply curves. The sam system presently has the analytical capabilities of simultaneously (1) evaluating many mineral deposits, (2) updating mineral supply information to reflect inflationary changes in costs and prices, and (3) conducting sensitivity analysis to determine impacts on mineral supply under various conditions. Many potential users in both government and industry will find the sam system a valuable tool for policy analysis, forecasting, and planning. The sam system has been constructed so that any types of information that are similar to the data elements in the mas data base may be used to perform supply studies. The storage space needed for the sam system's programs, files, and output data is approximately 14 million characters.
