I'm not a geo, far from it but on reading this: "Natural mattes, consisting predominantly of Fe, Ni, Cu and S fractionate to form a sequence of phases on cooling. Below ~1100°C, (Ni,Fe)S monosulfide solid solution (mss) crystallizes leaving a Cu-rich sulfide liquid enriched in Pt, Pd and semi-metals (e.g. Te, Bi, As). At ~900°C, the Cu-rich liquid crystallizes to Barnes et al Magmatic Sulfide Ore Deposits Elements Template Page 4 intermediate solid solution (iss, approximately CuFeS2), leaving a residual melt progressively enriched in Pt, Pd and semi-metals"

do you think there is more Ni to be found at greater depth particularly at Succoth?
Thanks.
