Taking the numbers from his presentation we end up with

$275/t production costs from known similar current operations
$1100/t delivered to gate in WA farmer price example.

$825 margin.

With target production of 6Mt to 37Mt makes $5 billion to $30 billion potential profit. Take that over 10 years we are looking at around $500M - 3B a year.

Even if you halve the margin we still end up with $250M - 1.5B a year for 10 years.

With so few shares on offer that would lead to very healthy dividends.

Very basic numbers but current market cap of $13.5M seems a little under valued
