How does a big holder selling lead you to the conclusion it will go to 60c? Seems a bit arbitrary. For all we know they've run out of shares to sell. Not to mention it doesn't say anything about why they're selling - do they need to free up cash, or to exit the company?

Anyway I'm not reading much into it, if copper or zinc moves, KZL will move with it. Today KZL is down sharply for no apparent reason (copper, zinc stable), represents good entry. Even so I'm on the fence whether to get more, as I'm a bit overweight already.
