I don't know too much about graphite, and know a little more about copper. Let's call copper $4/lb (which is close). 2200lbs in a ton is $8800 per ton of copper.

Let's say graphite is around $3000 per ton. That's approximately 1/3 of the price of copper.

When I look at these grades ranging from 4%-18% graphite and divide by 3 they look pretty nice considering 1% copper is a viable project.

Id like to see some longer intersections, but again - I'm not too familiar with graphite. It seems to me that there is money to be made here. I do know that graphite is a world easier to extract than copper.
