Re the core- the grey in with spod could cause contam without an expensive ore sorter.
Re pls the majority of their core appears clean?
Note:I'm not a geo so more a question.
Here's a picture of a clean peg. ore body approx 5m width, no dark colours withing although there is different colours of spod. PLS dig by colour and dark material goes to contam dump til they get the ore sorter installed.
