Cost and Time Analysis of the Mining and Environmental Requirements in the Premining Stage for Copper Mining in the Northern Highland, Wisconsin

摘要

The report provides the results of projected time and cost requirements for new mine development in Wisconsin and is based on a unique blend of information from mining company officials, State regulatory agency officials, and contractor experience. Lists of the tasks and subtasks required to plan a new mine were developed and times and costs were assigned. 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, respectively. 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.
