Working pocket 7

Sunday evening, our 3rd day of working pocket 7, I received a phone call from Dr William Simmons of the University of New Orleans. He asked whether he could come and observe the working of pocket 7.  We were delighted to have him.  I hoped , as did happen, I would have a chance to 'pick his brain' while the escape route was blocked. Fearing that the pocket might end before his arrival, I decided we would not work the pocket the following day. For 24 hours we sat with our legs tightly crossed. I need not have worried though.  Many more days of digging this pocket lay ahead.

Most of the large tourmalines were found during the first 3 days of working the pocket. They seemed to be concentrated on the left side of the pocket where a half dozen or more lepidolite lined  chambers radiated into the ledge.  Although originally the ledge on the left side of the pocket seemed to be schist, a small blast placed in this material showed it only to be a veneer. Behind this schist were small albite lined vugs with green tourmaline.  It was apparent that the pocket system had the potential to exist in the ledge to the left. Our plan for June would be to advance our pit both upstike ( Eastward) and down dip ( South) expanding the working face along two directions.
