Mineral Exploration And Mine Development

Ore is the rock from which an element ultimately will be extracted The weight percent (or grade) of the desired element in the rock varies considerably from one mineral to another at operating mines—much less than 1 by weight for gold than 60 by weight for some iron ore mines Ore usually is transformed into concentrate at the mine site

Real Options Valuation With Matlab: A Mining Economics

Now that we have calculated the NPV of the mine based on the GBM and HWV models we can run scenarios on iron ore prices (either mean reverting or based on returns and interest rates) First let’s look at a scenario that uses the HWV iron ore price model Figure 8 shows the NPV distribution of cash flow when running this model
