Any oilfield drilling experience in Canada will have no resemblance to the core drilling in Peru.
Even the tools and equipment is so ratically different there is no comparison , unless you run a water well drilling rig.
These core rigs are typically trailer or truck mounted looking at the websites.
As for management holding back results, I think the backlog for analysis is staggering with the recent surge in gold prices, and that is where we are at. Our samples are sitting in a que somewhere awaiting their turn. You can bet the Geo's have seen the cores but until they have been split and sent to 2 different labs the results can't be released as they will not be 43 101 compliant.
