Yes and that is for 94 to 97% you get up to $3,000 tonne with flake

From latest NR

Synthetic graphite is significantly more expensive to make but commands the highest market prices due to its purity. It can cost $4,000 to $5,000 per tonne (99.5-per-cent purity) to produce but can be sold for $7,000 to $9,000 per tonne.

Ultrahigh-purity (99.9 per cent) graphite can demand a price of $20,000 to $30,000 per tonne. Processing and purification of natural graphite have improved greatly in recent years, and projects with initial high-purity graphite, like the Albany vein type, require less purification and therefore lower cost to produce

As you can see it cost $4-5k for sythetic makers to produce 99.5%. Even more for them to produce 99.9%. Aubrey mentioned in Financial post

RW: When I spoke to you back in October, you told me the cost of producing synthetic graphite was quite high. How will your costs likely compare with synthetic?

AE: We don’t know yet what the exact costs will be, but we’re speculating they will be much, much cheaper

So for a much cheaper expense we can be selling in the $20,000 to $30,000 per tonne market!!
