Not likely. Their plant had a planned full output of only 8kt per year from memory. They never got anywhere near that after a long time of trying. Even if they did, it would not have covered expenses. Below are the financial quarterlies from the most recent (left) going back in time to the right. When they were producing (from Sept 2020 and earlier). I averaged over 8 quarters where they were producing, we have,

Average quarterly receipts from customers = $353k
Average quarterly expenses = $1875k

So despite their effort to get this mining to full production, their output and sales were only covering about 20% of costs. Graphite prices can not save this. The output is just too low, the carbon deposit grade is too low and the large flake size hype has not got them any special prices to offset this.
