Be interesting to see how much that cost is impacted by the inflation of fuel and labour plus the estimate was based on a run rate of 800K tonnes, so it'll cost more due to lack of scale during the pilot. But even if it ended up been $150/t cost the pilot plant would be making $45M AUD profit a year! Wonder if the company has gotten any offers from some major players, price is so cheap to secure a good supply.
