The arsenic in rock chips and sericite alteration suggests that outcropping rocks are well above the copper mineralised zone. Copper grades in rock chips are expected to be low given the geochemistry at surface. But the highest copper grades in a porphyry deposit should be in the intrusion cupola, which lies at depth.
Arsenic should fade out with depth, moly will increase peripheral to the strongly copper mineralised zone.
I’m really looking forward to the drone mag results. Drone magnetics will be a great tool for targeting long copper drill intercepts, because magnetite should occur alongside copper in the hotter potassic zone.
We need the geology gods to play their part but all the data says there is a pretty good chance of making a big discovery.
