What I don't get though is look at all the gold (red and purple dots all the way along the south and south east of the map) how/when do we find were that gold stops. We are not drilling there by the looks so how do we find out where that gold ends - for the mine plan to be completed wouldn't it be just as important as the gold on the opposite side of the map?
This current campaign will take until xmas to get results back and study them.
If I know the doc he will want to do another drilling campaign next year in that area.
It is a great problem to have - too much gold - but it is taking forever.
