I just noticed that on the HUI-Gold chart we touched the line of three deviations below the norm. That doesn't happen very often.
The upward potential for the gold and silver mines is extreme. So this must be a bottom, unless gold will go lower, which is unlikely.
It can be seen on page 5 of the public charts of Dan Caldwell:
