24 million tons X $61/tn = $1,464,000,000. These deposits in the Illinois basin are being extracted for as little as $20/tn. All in if costs are $40/tn (assuming the seam below goes much deeper) then profit margin is 34.4% for a profit of $504,000,000. If costs are $50/tn profit margin is 18% and profit is $254,000,000. There will be bumps along the way, but the point is this is a real company in a still vital industry staring at real revenues, real profits and tons of opportunity.
And it's not as if Landree Mine is its only property.
