[QUOTE="grubstake, post: 627046, member: 4012"] Don't be mislead by amateurish talk of the carat (karat) rating of gold, which is really only applicable to the end-product of refineries. Carat rated gold was originally purified to 99.99% bullion (so-called 24 carat gold), and then 'diluted' (primarily with with copper and silver), to produce a specified purity, colour and hardness. With raw/mined gold (ie. nuggets, crushings, fines), the actual percentage Au is the only meaningful measure of purity. Even the end-product bars from minesite gold rooms are variably impure and these are known as dor bullion: Dor bar: [url]https://en.wikipedia.org/wiki/Dor%C3%A9_bar[/url] [/QUOTE]
