This has to do with a falling dollar.  The price of copper is as illustrative of the decline in the value of the dollar as it is for most other hard assets. 

BTW, I think it was Rick Rule who pointed out, at least indirectly, that base metals needed to catch-up to what happened earlier this year with regards to precious metals.  While he was speaking more specifically about the first ever leap junior minors took over major producers at the start of a new cycle, this can better be seen in regards to precious metals v. base metals producers. 

The US dollar is down .43 percent at the moment.  Here's what the last year looks like.

None of this matters for LBSR, in my opinion.  ...too much old meat and not enough vinegar.
