That begs the question of whether we should need a full scale open pit mine as planned years ago for the purpose of extracting high priced graphite for sale.With graphene,a little goes a long way as demonstrated.Why not just build a small scale underground mine with a ramp to get into the high -grade sweet spots and take out what the company needs whenever it needs it.That should eliminate the problem of having to raise hundreds of millions to kick start the proposed mine.
