Fools Gold with Gold and Other Sulphides

Gold on Quartz with Arsenopyrite (arsenic sulphide) on a slate base

Pyrite with gold, pyrite (iron sulphide) is hard and brittle, decomposes to red rust on exposure to the elements



Gold with Galena (lead sulphide), usually contains some silver, sulphide mineralisation is a good indication of reef gold.



Chalcopyrite (copper Iron Sulphide) due to the copper looks more like gold, another fools gold, is hard and brittle

Thanks tezz ,the best examples with descriptions, l have seen .Regards keogh.

Mineral collectors will pay a premium for good quality combination specimens showing gold with other minerals or gold with quartz crystals, so don't throw them in the dolly pot.

PLATINUM

SILVER COPPER HALF BREED

STREAM TIN (CASSITERITE)

UNKNOWN NUGGET, found this in the bush in the Ballarat area, it is not gold, will need specialty chemicals to test it.
Regarding the other specimens I did not take the photos as my camera has poor depth of field with macro lens,
in other words not all of the specimens would be in focus.
As you can see gold can be found in all sorts of material.
enjoy
cheers Tezz

Really interesting, thanks guys just goes to show how maybe the surface indicators can vary so much and not to rely on just looking for the old "Salt and Pepper"
