The RC drill will break off some smaller pieces of NCu but by and large it will not capture anything great than a 10 cent coin in diameter. Its solid metal and the drill just can't get through it, like it does very fine pieces scattered through solid rock.
I spoke to driller on-site and saw the clay samples for myself and have no doubt the RC drill process would push NCu nuggets aside in the 'clay' like mineralised zones.
I have a video on YouTube from my visit that shows the copper in this black clay like material...between 18 - 28 second mark of the video.

All of that aside my point is the jorc process, with kriging, variography, and smoothing etc is not designed to report ore bodies like Rocklands accurately. Whatever NCu was captured in the drill process, then assayed just isn't fairly reflected in the jorc imo.
I wont go on any more as it's probably driving some people nuts, but if you read my posts today you may hopefully start to understand what I'm banging on about!
