UPDATE
June 30,2014 These are just a couple of charts to update how I am watching things unfold in the MINERS. We had our first run up, which I believe is just the first leg up. A consolidation has begun, as did in the DEC run up. Is it finished? Maybe, Maybe not, but if I'm going to establish a position in your favorite Miners (As a core) or trade , I don't want to wait until I have to chase.... you want to try to find low risk entries using charts. Risk / reward is better at Support areas, certain Moving averages, and even a break out of a consolidation one can enter a low risk entry....and then keep our eyes on it to exit if it turns against us.
With that in mind...I was watching GDX, GDXJ for clues , and JNUG for an entry . GDX does have lightish volume today, but is that uncommon before it approaches a break out area? Notice the 1 hr chart. (Click charts to enlarge)
