Had trouble editing the last post, here is what I wanted to add:

I believe there are only 2 prodcuiong mines at the moment, Eagler Graphite is one at 4,000 tonnes per year, as follows:

In 2006, the Black Crystal graphite quarry and processing plant were acquired by Eagle Graphite, a privately owned Canadian corporation based in Courtenay, British Columbia. Since the purchase, Eagle Graphite has invested in retooling the operation, which now has a production capacity of 4000 metric tons per year of high carbon natural flake graphite, with a projected capacity expansion in the near future.

As one of only 2 producing flake graphite mines in North America, strategically located close to both the US city of Spokane, Washington and the Canadian port of Vancouver, British Columbia, Eagle Graphite offers efficient and economical shipping of high grade material to destinations worldwide.

Smaller operation with 93-99% purity.

Ontario graphite is another producer.

Interesting that both of these are privately owned. Something I am not sure anyone has mentioned here. Someone could buy ZEN and simply btake it off the market, we would never know the prices and production levels.

And most or all of the larger non-mining deposist in NA are flake. So back to the original question and I am not trying to be comical about this - is there another alternative for Tesla if they want to replace outside NA synthetic with inside NA natural?
