Ann: First Mixed Rare Earth Carbonate (MREC) Produced at Caldeira, page-28

Hello. I did lots of homework for my VMM investment (which is now sold because of MEI's smaller mining tonnage goal which i assume is 5mtpa rather than the 10mtpa and 15mtpa people here were entertaining). Unlike MEI, VMM has announced lots of RC and diamond drill results. In the northern VMM tenements, the average depth is around 24 metres. In the more middle tenements (Cupim South), the average depth & grade is greater. New results due very soon for VMM's Cupim South.

MRE is modelled to an average depth of 10m [looks like my 9.9 metres was correct] and deepest resource modelling currently ends 25m below surface

Therefore, i could only find the Capão do Mel drill results above with average depth 25 metres or 28 metres if we ignore the 5 metre hole. Figueira looks like the best depths averaging 48 metres.
