I have posted about the geochem before. Will post again. Below shows Cu (ppm) that I downloaded from a few datasets on geoview website (with AEM image underneath). The Au and As look similar, but lower ppm numbers. First image shows the samples (which do not include locations shown on your map in the brown Western gneiss ... I didn't see these on geoview, but maybe I didn't find all the data). The other is gridding these samples to make a map.

Can't do this for things like Ni, as the existing data is unreliable. There are some elevated readings (mainly near Ablett), but most of the sample locations have no values. I don't think they were assayed properly for Ni-Pd-Pt, as they were mainly thinking about Cu-Au.
