Went out on the weekend - not sure what this is?

Also Native Platinum is about as heavy as Alluminium due to impurities/contamination/aeratition.

Native Platinum is "heavier" (higher specific gravity) than gold, about eight times that of aluminium. Why don't you determine Specific gravity - it is easy to do and will almost certainly give a definitive answer - in this case much more sensitive than other methods?

Platinum 21.45

Gold 19.30

Lead 11.34

Copper 8.96

Aluminium 2.70

Do a search under goldierocks for:

Series on identifying minerals - part 8 SPECIFIC GRAVITY

The flame test for copper is also sensitive - green to bluish green for copper (aluminium gives white, platinum gives no colour to the flame)

Series on identifying minerals - part 7 FLAME AND BEAD TESTS

That is why I posted the various tests - so many minerals can be easily identified using them (you guys make life hard for yourselves).

Native copper is common in the basal part of the Late Devonian rocks around the Macalister River and adjoining areas. No gold with it.
