You summarized things very well frtaylor - pullback off today's highs so far has been on light volume so could recover next week. Watch to see how it closes (gap below).

Many would have never thought to put that wedge line in there which has acted as resistance.

Overall, GDX is still in an uptrend (always difficult to pick exact tops) so trade according to your objectives and risk tolerance (that means have a proper stop in place that coincides with your risk level).
