2. THE MANAGEMENT OF A MINING OPERATION

2.1. Management structure of a conventional operation

Table I is the organizational chart of a conventional mining operation. A conventional mining operation is divided into four main activities and departments that are: the mining department, the milling department, the maintenance department, and the environment department.

For a single project the overall management is assumed by:

a Vice President for Mining reporting to the Chief Operating Officer. He directs, control and administers all mining and milling operations. He is responsible for achieving production objectives and for improving the overall cost and efficiency of the operations through careful long and short term planning, budgeting and control.

This position requires a degree in mining engineering and a solid experience in all aspects of mining including economics and at least 15 years experience in the mining industry.

a General Manager reporting to the Vice President for Mining. He holds the most senior on-site management position with overall responsibility for cost-effective mine site production, processing, engineering, maintenance and administration. He is also

responsible for capital projects and development projects on the property. He develops and implements company policies and procedures to facilitate corporate objectives and implements a strategic plan given by the Vice President. He also provides information for the preparation of a strategic plan. The four departments (Mining, Milling, Maintenance and Environment) report to him.
