Russ, I use $1.00/ton for mining (waiste or mineralization). This will go higher if the rock is sulfides (conventional mining) and need blasting. <Also in heap leaching operations a range of $5 to 8/ton is used to express a typical processing cost.> In fact I think it is more like $3-$8. With many falling below $5. As an example, BAY is working on the assumption of Mining and waiste removal $0.75/ton Processing: $3.00/ton >What variables dictate where the final number may fall? Size of course is the main one, but any others? The processing in open pit heap leaching is fairly constant... I am not sure which one are the most important variables.... electricity, water, reagents...etc are all components. I doubt that any of them factors will have more impact than the cost of mining. You will often see in the total costs, the cost mining (waiste and mineralization) being higher than the cost of processing... Strip ratios of 3:1 and above are not rare.
