RE:RE:RE:Pro forma consolidated financial CXB circularP/E is not the best way to compare two mid-level mining companies. It does not take into account mine life-spans, for one thing. Or debt. Mining companies are good at reducing taxable earnings, by various accounting tricks, so they can use a larger fraction of their cash for growing and developing their properties.
Reserves, FCF, production growth and AISC are all better metrics.
Also, relative GEOPOLICICAL RISK needs to be factored in.
I once bought a mine with a great P/E only to discover that it had shut down its mine! Of course, the earnings were the trailing earnings while the price was the current one ( the mine eventually reopened but it was a long wait).
