Others have responded with regards to the occurance of pentlandite and nickel. It obviously is a very important mineral within the context of McFaulds. NOT's Eagle 2 made mention of it once again.
Here's a neat web page on magmatic sulfide deposits showing pentlandite (small black nodules). Remember, the SPQ-FWR is a MMS anomaly.

Sorry to state the obvious again, but assays will tell us exactly what we have - and it surely will contain some nickel. However, I think PGEs will be king.
