I meant to post this earlier, but only just getting around to it now. Below is the Cu ppm from historical open file data (can be downloaded from geoview website) that I gridded up, including CVV's copper asset to the north for reference. I placed an AEM image underneath. The Au and Pb were similar in character, but lower ppm numbers. Phil's Hill is near a Cu anomaly, and the two main AEM anomalies (for which I still have no idea what is the status with MLEM) were not covered.

The minerals and rock types found in exploration at A1/Ablett led CVV to speculate that a VMS system could be possible. That would not be a PGE-Ni play. There are two broad types, either Cu-Zn or Zn-Pb-Cu, and both can have minor Au-Ag (and Pb for the Cu-Zn type). The most common sulphide is pyrite, and pyrrhotite can also occur. Both of these can produce strong EM conductors.

The Pd-Pt-Ni historical geochem seemed unreliable to me. There were indeed some elevated readings. But the high numbers were located where the next line over was zero. So I don't trust the open file data for those minerals. The copper assays seem to at least be consistent-ish from line to line. At this stage I believe the best shot is finding Cu. The latest announcement from PUR says they will be doing their own soil sampling, so I am very interested to see whether it reveals better Pd-Pt-Ni numbers.
