Just to add, understanding of porphyry’s, particularly alternation zones; has really developed even in the last 5-10 years since AA last had a look.
They also did mainly RC drilling which is cheaper, but you miss out on a lot of info such as intrusion directions and layering.
They also drilled to a shallower depth.
Finally Anglo obviously quite liked what they had found there. They had a decent team and (for them) did a lot of drilling.
My guess is that they weighed it up, but didn’t quite find enough at the then time to do further exploration. At the time copper was very unwanted.
Again just imo.
But the directors refused to sign off on the 10-30m that more exploration would have taken, the majors were going through a down size at the time, limiting debt, reducing leverage. They would have been cutting everything that wasn’t a ‘core’ project.
For xtr they were lucky. But to come along, pick it up, do more drillling than Anglo ever did, find the deeper mineralisation, increase the extents, delineate ascot, perform deeper geophysics- it was more skill based.
Whatever xtr finds - Anglo will reassess, and decide whether a copper resource like this will fit into there portfolio.
