In answer to your question:-

For Cobalt 0.08% is generally viewed (and similarly 0.5% Copper) as a economic resource depending on size (for economies of scale), depth (shallow better) and location (close to buyer or transport like rail) and assuming workable metallurgicals. Generally most deposits like CLA will be subject to zonation...or areas where there are higher grade and lower grades across the deposit. The fact that they have maintained a headline average grade of 0.11 % Co grade across such a large deposit is good IMO.

PS: Disclosure - I don't own CLA and never have and was using it as an example of JORC upgrade and shareprice reaction to it as can be applied to AVZ when our maiden JORC comes out.
