If you look the ann. the winzes were sunk by hand to provide bulk samples for analysis and metallurgical studies. If they were of no importance they would not have been done. They were done in my understanding because they could not get hold of a drill rig. They will provide %Fe and that is what we want to see ... not stony silence.

But I guess percentage Fe is of no importance in an Iron ore play, my mistake.
