In terms of the pricing for a cobalt or nickel sulphate . . . a cobalt sulphate contains about 20% cobalt metal. Nickel sulphate similarly contains about 20% nickel metal.

Therefore, in rough terms, 1 tonne of cobalt sulphate sells for about 20% of the price of a tonne of cobalt metal. Same goes for nickel sulphate.

So in an Australian Mines presentation, were we state that we are seeking to produce 100,000 tonnes per year of nickel sulphate, this equates to about 20,000 tonnes of nickel metal.

And where we state an annual cobalt sulphate production of 12,000 tonnes, this is the same as 2,500 tonnes of cobalt metal.

Therefore, our pricing numbers are based on the LME price for cobalt and nickel metals, multiplied by 20% of the expected cobalt sulphate and nickel sulphate outputs
