Ann: Black Rock Mining AGM Presentation, page-12

I was just about to ask the same question.

“One of the first things we noticed is that our graphite is actually very clean, it's quite easy to separate as well which is very important. So when I say clean, we don’t have any deleterious elements. Often you will hear, particularly with projects in Mozambique – Syrah and Metals of Africa they certainly have a lot of Vanadium. They believe that is a bit of a positive; I guess the jury is still out on that to some extent. But that is something that we don’t have to worry about as our graphite is indeed very clean.”

Where are you getting your info @ddzx
