My current favourites are Galina (ASX:G1A) which is a lead/silver developer and Aeris Resources (ASX:AIS) a copper producer, but which is currently drilling a very large IOCG deposit in South Australia.
If you are interested in learning about Australian mining companies then take a look at Hot Copper. Watch out as like most stock internet message boards there is a lot of ramping, but there is also a huge amount of useful information there too. Just make sure to check everything you read yourself.
