Total Copper Resource, page-14

gnessic,
Thank you for an excellent post. The June quarterly has the following :-
"All evidence to date suggests significant underestimation of copper grades during sampling and assay when coarse native copper is present.
Mining of the supergene zone appears to support the Company's long held view that copper grades are underestimated in the coarse native copper and chalcocite zones, based on twin-hole programmes that compared copper recovery in RC and diamond drilling, and in a separate twin-hole programme that also compared chalcocite recoveries for each drilling method.
Mineralisation is open at depth. Current estimates are restricted to those expected to be reasonable for open pit mining. Limited drilling below this depth [-250RL ] shows widths and grades potentially suitable for underground extraction. CuDeco are currently considering target sizes and exploration programmes to test this potential to 1,000m from surface ".
