One other thing that may be relevant to KZL recently is the furious pace of Chinese lending is being slowed (and it was furious) which has lead to some concerns about inflation in China and particularly demand for commodities.
The good news IMO is that the news is probably reflected in KZL's current share price. Unless China blows up the outlook for KZL is positive over the long term, although China's rate of lending over the last 12 months has probably contributed to bringing a lot of demand forward; hence the current voaltility in share price.
