"Apney munh aap mian mithu"
ALL of these sources are unverified bullcrap as far as the overall magnitudes of the resources are concerned. There are exploitable quantities of some natural resource in a few locations, and their profitable use requires co-ordination of many aspects that are beyond Pakistan at the moment.
A close friend of mine works for a Hungarian company MOL, on site in various regions of KPK, Pakistan. He has personally told me of the vast gas resources there are in KPK, as well as oil reserves. I'll get some data from him to contribute more on this thread.
