RE:Is there a standard pea discount percentI tried to replicate the PEA with a quick DCF in excel. Here is what I am getting for pre-tax NPV's based on the discount rates shown. As you can see I'm not exact to the PEA but ballpark (I was using the Feb 2013 data) https://www.energizerresources.com/2013/329-energizer-resources-announces-positive-preliminary-economic-assessment-of-the-green-giant-molo-graphite-project 6% 663000000 8% 534000000 10% 434000000 12% 355000000 14% 291000000
