This report provides the results of a 2-year study of the projected time and cost requirements for new mine development in Wisconsin. Critical path method diagrams were then developed for a generalized mining project. Total time and cost for the premine planning process was estimated to be 25.12 Years and 223 person-years of professional time excluding public affairs effort. By eliminating redundancies in the process and by increasing project efficiency through early public review and participation, recommendations were made to lessen the time and lower the cost of premine planning. The streamlining recommendations could shorten the overall critical path length to 17.16 Years and lower the cost to 208 person-years of professional time excluding public affairs effort. The estimated distribution of professional effort for mine planning in Wisconsin approximates 50.5 pct for traditional mine and engineering tasks, 36.6 pct for environmental-regulatory tasks, and 12.9 pct for traditional geological-exploration tasks.
