More than that you have to look at the cupriferous archean island arc platforms that were high in felsic rocks for our model and also co-incidentally near sea floor spreading zones. Actually it's not a coincidence. The islands would not be there if they were not near a spreading sea floor or a rising plate. Either one will do. The next thing you look for is porphyry development and sea floor silica and carbonate, magnesium, managanese horizons. Copper and zinc in the deep silicate plumbing systems (qtz veins) near pillow lavas is a good sign. In a micro environment the lavas should border sediments and show a marked transition between different ages and volcanic piles. This shows preservation of the pile by early diastrophism. This helps the rapidly erodable sea floor deposits to be protected.

The approach Kauffman took with Hudson bay in Manitoba is to go into the so called Andesitic terranes and drill every conductor with a fast rise time. Ultimately it was successful. Nobody has done that except Britt Lang in Ontario and that was a long time ago. Lang's drilling was all to shallow. Today we should be following up in the felsic piles and doing the IP and drilling like mad way down to 800 feet and beyond. That is what extended the Noranda camp under Falconbridge. also drilling IP is the only way to penetrate the overbdurden. A little pragmatic MMI or such deep penetrating geochem might help to experiment with as there are promising anomalies in the Timmins camp from this method.

The so called Andesites may just be silicified rhyolites. The are not alpine rocks at any rate, as close to pillow lavas in composition and deposition as they are.
