Have to respect the market. Interested on others thoughts particularly the sceptical. If you worked at a mine site, how easy would it be to know if there was a problem with the overall progress of the various operations? Not hard I would have thought. Secondly, are there restrictions on trading the stock if you are a non corporate employee. eg excavator operator or truck driver. I cant imagine events or problems can be kept quiet and could easily be passed around at lunch or in the pub. If you were a serious investor eg hedge fund operator or heavy hitter, how hard would it be to get to know these peeps. Reconnaissance work like the big short. Some workers/operators have even commented on here but not as much as I would have thought. This is a general question for the mining industry not just for BCB.
