a) wave 1 is completed and wave 2 is forming an expanded flat. Having recently completed the b-wave, today's drop likely begins an impulsive c-wave back to at least 16.24. The lower portions of my wave 2 box seem unlikely, but only below 11.10 would impulsively would this alternate count seem questionable.
b) Wave (5) is forming an illustrated with purple. Several other miners have similar possibilities, including GDX itself. This channel is not fully formed and certainly may have a lower slope than shown. Breaking 16.24 would clearly invalidate this potential.
