well as we know BZW is very close to RMS kathleen valley project which is due to run out of high grade ore later this year ....now if RMS doesn't discovery much more high grade I can't see the point on continuing to freight the leftover lower grade ore 200kms+ to their Gold plant.... when BZW is only down the road 40-50kms?? ... so a sale or toll treatment would be a good for both parties..
