This statement indicates the similarity of the deposted lenses from the ultramafic flow in the Timmens area.... This intrusion was not on surface, a river of magma flowing sub surface from somewhere... to somewhere..

Therefore the indications that PRB and FNC are within this ultramafic intrusion indicate they are within the correct structurally contained environment to produce a deposit..

In the Timmens model I posted from the LBE site what is showing is the shape of the confining structures allows the heavier Ni/ Cu pt pd etc to deposit in low areas as the material flows trough the structure.

With this in mind it is inconcivable that all the heavy metals condenced out of this solution and that similar structural controls will provide additional deposits.

Critical mass will be achieved via the drill bit following the structural controls untill the correct environment allowed the percipitation of the metals. Deep structural pockets will provide opportunity for drilling. Drilling the peridotite to depth a must as these lenseswill be hosted in the bottom of the structural control.
