Ann: High Grade Drill Results from the Central Graphite Zone, page-74

They had to process the crap out of it, leach it and that produced a low percentage con.
They may be able to process it more and throw more leaching agents at it, but even if they scratch it close to battery grade it will cost more ton to produce than they will be able to sell it for.
If you have a huge piece of graphite and you cut a chunk out, you will get near pure graphite. However, if you take the same volume of micron size graphite the surface area of the graphite becomes significant, and this is typically where all the deleterious material sits and why amorphous graphite is not suitable for batteries. Then there is the spheronization process which requires 100+ micron for feedstock. The misguided people on here banging on about batteries needing fine and amorphous flake is nonsense. What they are incorrectly referring to is the final product spec.
Not investment advice but far more accurate information than the one-eyed fan club around here.
