In my humble opinion I really think this is a case of some holders thinking that extracting resources from Mother Earth is a straight forward, uncomplicated and standard process.Clearly under normal industrial manufacturing this is pretty much the case. If a part of the process breaks down you can see it evaluate it and fix it.
I would think that given the unknown (and some known ) obstacles that extracting resources will always present it is not unusual to expect and be set back by something that you can not see coming.We can not simply lift the lid here and have a bit of a look. As is often the case I think some educated guess work must come into play.

I for one think that we are very lucky on the NWE forum to have access to the fantastic input by some very knowledgable posters who clearly know a lot about this business.
