Vein Graphite - Rare and found only in Sri Lanka, page-14

Some valid points but a few queries..

1. High grade yes but exactly how much Graphite is contained  in these veins, whats the Jorc tonnage
2. What is the strip ratio (Assume a lot of waste)
3. What volumes can they output per year in terms of tonnage.
4. Given you have to move a lot of dirt to get to vein what are the likely all in total cost per ton to port
5. Versus very large scale open cut graphite mines with simple flotation methods ...vein it would seem is  very expensive to mine , I presume  all ore is at surface and they do not need to go underground (if so additional costs)
6. My understanding it that current mining methods are inefficient/labour intensive  (ie,limited mechanisation) some is even dug out by hand if so...very low tonnage likely
7. Some Graphite has been refined to 99.96 % Purity (In Canada I think) how does this stack up against BBR Vein ore
8. Sovereign risk - what is the current state of political unrest /terrorist activity in Sri Lanka

Just queries at this stage to get a full picture
