mining cost per tonne by mining method

For 1999 and beyond, mining cost per ton is expected to be in the range of $0.85 to $0.90. The depth of the pit and the height of the heap leach pad impact the truck-haul cycle time and unit cost, which is the most significant component of mining costs.

As the cost to mine waste is less than the mining and treatment costs for the ore, the cost per tonne are likely to be higher for the latter case, if all other factors are equal. Variation in underground operating costs will also be influenced by the type of mining method employed and the factors such as shaft haulage versus declines.
