So after a little further research.

Black Swan and Silver Swan:
In 2006 Black Swan and Silver Swan produced 7200 tonnes of nickel and 150 tonnes of cobalt for the year.

Emily Anne:
In 2004 LionOre provided Inco Ltd nickel sulfide concentrates from the Emily Anne mine to produce Cobalt Cathode.

Windarra:
Copper and cobalt are minor secondary credits associated with the Windarra ore, which will be credited to Poseidon Nickel with the sale of the concentrate. There was a strong correlation between nickel and cobalt, nickel and iron and nickel and sulphur. In some cases there was also a strong correlation between copper and cobalt.

POS expects Mt Windarra cash operating cost to be US$3.20/lb of Ni at a run rate of 10ktpa Ni. This is relatively low compared to its WA peers, which have costs of US2.12/lb to US$5.10/lb depending on the mining method. A cobalt credit of ~$1m per annum is expected at current prices. A cost breakout and peer comparison are shown in Figure 5a,b. These costs may change when the final FS is released in late 2011.
