I think it mines on the basis of a strip mining operation.
Bulldozers, end loaders, large trucks, etc.
Large mining trucks can carry about 80 tons, plus each load.
Cost of operation would be based on amount of equipement and employees.
If they mined, moved 1,600 tons a day, and finished processing that amount at 17.00= 27,000.00 a day.
Specualtion on my part here.
Worth the effort, on revenue, or I guess they would not mine it.
