If you look at the Cassini intercepts they contain a bit of copper and cobalt (same as their other assets). And the MCR DFS shows a by-product credit offsetting some of their unit costs. I'd assume they're getting a bit of revenue on the cobalt (cobalt payabilities are usually pretty bad if I recall correctly - you can broadly work out what IGO's are from their financials). If you take that by-product revenue off the top-line revenue number I think that'll get closer to the payability number?
