I agree and also think large flake and course flake is the same. So far ZEN has drilled only a few holes so I have not found much to go on with the flakes. I do know that NGC has a very high perecentage of large flake graphite.
What sold me with ZEN was how well it compares with a mine in Sri Lanka and I read where it has high priced graphite. Zen, it seems, is just the second mine like the one in Sri Lanka. Hopefully, this information turns out to be true. Also, if the drills indicate the graphite mine they outline will be as large as they think, Zen should turn out well. There is always the risk to consider. NGC has much less risk.
