For the same reason why I started buying when it started dipping below 3c - I think that Zinc resource is outstanding, there's a potential for Silver (though high grades need to be more consistent to justify mining this deep - so not feasible yet), and Lead is also worth something. Share price might dip below 1.6c (especially if Paterson is too keen to get rid of excess shares), but that's not certain, so 1.6c now is good buy without hassle.

There's a question on strategy and why they're not doing CR to prepare for production, but for more drilling. My guess is that they don't really want mining with just a small resource, but to increase the resource (and based on results so far, there will be an increase) and then look for large strategic investment to start larger-scale production (current facilities are not big enough).

IMHO the biggest risk is that Copulas et al. keep diluting with further CRs, push the price lower, then another consolidation, etc. That might happen, but the upside is far bigger - CZL could easily become multi-bugger in the next year (especially if directors will be motivated to get those performance options).
