If the results of the feasibility study indicate that an adequate economic return can be expected from the investment, the principal steps that are then taken to develop and construct a mine and mill include the following:
- securing all licences, permits and other forms of authority required for construction, commissioning and operations, including those of an environmental nature;
- consultation with local communities in relation to socio-economic impacts and to ensure that local residents and businesses are afforded the appropriate opportunity to participate in the undertaking;
- arranging for the financing necessary to complete development and construction;
- completion of the detailed design of the mine, mill and infrastructure;
- development of an open pit mine, an underground mine or both;
- construction of the mill and ancillary facilities; and
- engaging the employees and contractors necessary to undertake full operations.
Development and construction are usually undertaken by contractors, commonly under the direction of one principal contractor. The overall process may take from two to five years or more depending on the complexity of the operation and, at the outset, the time required to obtain all necessary licences and permits.
