That was to be a main haulage adit. It was driven in across the grain of the rock and crosses several veins, but none were worth developing. The material in the waste rock pile was 90% country rock of no importance. Only where it crossed a vein was of interest. But after they crossed the area where there was an outcrop on top and found nothing, they gave up. This is the most common mining result, that stuff on his fingers is clay.
