Nice find Chucka!  I don't know that I ever looked at that page and I found the first picture unusual with that extra bold circle added in the lower left part of the Aerial Mag survey, outside of the area of interest, and from what I can see, that circle is outside of the claims that we handed over to the operator.  So its quite a curious variation of the map that I was used to. I always thought the pink and purple colours looked pretty interesting just south south west of the main pit and posted in the past my version of it with an extra circle in that same spot.  Cool!
