This one has been hashed out a few time here.

Not so crazy.

Gold is the Noble metal and will not oxidize unless forced .

Will not corrode in any fashion unless forced.

How ever Indicator elements and associated mineral do produce detectable smells and flags.

Here in New Mexico, gold is associated with Iron and Quarts.

Iron produces a smell.

Even I can smell Iron Oxides.

Some Sulphide produce Gold, Silver.

I can smell the sulphur and do further testings.

I do think this could be used to the advantage.
