I meant to say also that I have an inkling that the players at the northern end of the Julimar complex are coming to terms with the geology and the nature of the potential deposits. If so then it is a matter of time till they make great progress.
There is much written about layered PGM deposits (in Bushvelt for example) a lot very technical but interesting all the same - start as usual with Wikipedia

For those with physical metallurgical knowledge, the formation of pearlite in mild steel is analogous to proposed phase change phenomena in magma (as temperature, pressure and composition change).

Gl all.
