Operational and economic efficiency To turn what's on top of those trucks into an asset requires a plant that can process more ore. For Robex, profitability is obtained by the volume treated rather than by the gold content, in addition to the reduction in costs, consequent to less material to be moved to the disposal site.
As each elevation is ~10 meters and has an inclination of ~70 degrees, try to imagine the initial costs and the tonnage to be moved to extract ores sometimes located at 100 or 150 meters deep. That said, the gold grade must be put into context with its distance from the surface. Otherwise, the analysis of the quality of a project is impossible. In other words, don't be put off by the gold content.
These factors are important but they represent only a fraction of the whole that enables Robex to achieve economic efficiency.
