Mining Project Operating Amp Capital Cost Curves Revaluate

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.
