Recently a post suggested that a mill could be set up on the Tesoro plateau. Would this be a ball mill to crush the quartz etc. and then this sand- gold- quartz mixture be taken down the mountain for the jigging process? I'm not familiar with that next step (jigging) but it is my understanding that this jigging requires water under pressure, and it would appear that quite a bit of water would be necessary; would this be practical?

My question is, if the buyer built a mill at the top, to what extent in the complete process could take place at that elevation?
