‘T
he best-maintained VW Golf will never become a Rolls Royce. If you want to drive a Rolls Royce, you simply have to buy one. Tis same principle can be applied to all assets,
including mines and mining assets. A common objective of asset management is to minimise the whole life cost of assets, but there may be other critical factors that have to be considered, such as risk or business continuity. In the current economic climate, implementing a ‘Rolls Royce’ mine would be very difficult to justify from a pure business perspective, however spending more in the mine’s initial development phases may be hugely beneficial over the full life cycle. ISO 55000 defines an asset as ‘an item, thing or entity that has potential or actual value to an organisation’. Asset management in turn is the ‘co-ordinated activity of an organisation to realise value from assets’. It involves the balancing of costs, opportunities and risks against desired performance. Tis balancing act needs to be applied over the full life cycle of an asset. In general, the expenditure required over the life cycle of a mine can be indicated in the Influencing Life Cycle Cost graph: Te red curve, ‘% Expenditure’ shows the typical cumulative expenditure over the

life of the mine. Tere is a certain level and tempo of expenditure during the concept and design phases of the mine that increases significantly once the implementation and construction starts. Tereafter, the level of expenditure drops to cater for operating and maintaining the infrastructure as well as for the continued expansion. At the end of the life of the mine, expenditure once again increases to accommodate for mine closure and rehabilitation. Te green curve, ‘% Opportunity to Influence the Life Cycle Cost’, indicates how the ability to influence the full life cycle cost (or whole life cost) of the mine decreases rapidly during the concept and design phases and through the implementation phase.
Te purple dashes ‘% Locked in (Embedded)
cost’ show that the major portion of the full life cycle cost of the mine is already determined in the design phase of the mine. Once the mine is fully constructed, the options to influence the total production cost become very limited.
Significant savings
Even though cost savings are not as dramatic when recognised Asset Management practices are implemented in the later life cycle stages, these savings can still be significant. Effective
