I noticed South 32 is in the list.
It owns operates the Cannington mine which few years ago was the biggest in the world.
Falling grades and lower mining activity have pushed it well down the list.
It is still the biggest in Australia, but its a pretty small part of S32's income base.
It is moving away from metallurgical coal to base metals.
When you look at the breakdown, of revenue, Alumina and Aliminium make up about 4 billion revenue, Manganese 1.5 billion, coal 1 billion and copper silver lead etc make up about 1.7 bill.
The sale of coal assets in Sth Africa and purchase of a copper mine in Chile highlights its further move to base metals.
The silver part is just too small to have a material effect on the SP.
If you are willing to trade on international markets, CDE, which used to be Coeur De Lune silver mines, is another I have traded in the past, though it has become as much a gold interest as a silver interest.
Hecla mining is a Canadian silver miner that is one of the few almost pure silver plays, and is one I have started doing a bit of research on.
