The picture of a drill core freshly pulled from the ground at the NAK project looks very blue also,note the gold coloration going thru the core. Also these look to be smaller diameter core than the core#1 from BCSP. The blue is a geo flag that denotes a presence of COPPER in a poriffery. We already have our assays, if you will by default, amatures need to study some geology and it would also be worthy of them to examine NAK cores for express relavence of geological likenesses, as the BCSP core#1 is appearing very much like of relavent compatibality at the same depths as the NAK project cores. A little perussing thru NAK web pages will reveal the likenesses, just as you have mentioned.
