I have a question regarding one of the reasons for capital raising which concerns the possible installation of an underground pilot plant to reduce tonnage by about 80% and increase grade by a factor of approx. 4 times in concentrate form - does that mean that if such a proposal was cost effective and installed, NTL could adhere to their "Resource Consent" limitation of 100,000 tonnes pa but achieve a gold yield of 4 times that which would happen if the 100,000 tonnes contained about 20 gpt. To clarify further, does the
limitation of 100,000 tonnes mean "ore brought to the surface" and this plan would be to ensure that the ore selected underground had the highest grade content they could achieve?? Aplogies if I have not done this correctly - have only previously posted one comment?
