Using your first reference above, it basically means that the drill hole intercepted an average of 45.4 gT gold across an intercept of 1.3m. Within that intercept was 40cm which averaged 144.5 gT.
Referencing MS - it is a narrow veined "nuggety" deposit. The gold lies within the quartz reefs that are intrusions into the surrounding host rock which is a very hard granite (diorite). The issue with the previous owners MCO is that too much of this diorite was thrown in with the quartz into the mill and could not be properly crushed. Basically the diorite became golf ball sized "ball bearings" and basically interrupted the milling process and hence the lack of gold recovered...it was spat out into the tailings.
So, considering Keith Goode's evaluation that MCO were mining on the wrong side of the dyke...as I understand it, they were also not selecting the right raw material and therefore not getting optimal efficiency with the crushing.
The current management have taken the previous issues/challenges into account and addressed same...so hopefully a better process can be achieved and hence better (and economic) gold recovery can be achieved.
I suppose we will know shortly whether these challenges have been overcome and whether Stacpoole zone is a goer or not.
