Tengraph Mine Symbols.... Colour

Some years ago orgainsed a 20A near some mines I found on Tengraph, Self/wife and a friend duly rocked up towing caravans well off the main highway to find out they weren't old gold mines.

I know in some instances you can look at the mine info to work out the type of mine, but I also thought you could determine by the colour of the crossed picks eg red for... and dirty yellow for gold.

And picks facing down for an abandoned mine

Comments appreciated along with colour/mine info.
