OldGeo - here's an update with data from GSR, 18.8.22, Appendix1. They used different terminology in the MTJV001 drill log and I've added it as written. I guess "sediment" corresponds to "black shale/chert" or "black shale". Re your comment "my main question would be how to extract the metals economically/ efficiently" - perhaps a knowledgeable reader can comment. Thanks for the comment on the black shales - the tech paper looks a bit dense for me but I'll skim through.
