NRP will be paid a throughput fee ranging from $1.05/ton to $1.17/ton over the first 20 years of the agreement for all coal produced from the first longwall installation and the associated development units. NRP will also be paid the greater of 3% of the gross selling price or $1.14/ton for the tonnage associated with the contractual override, which has an anticipated life of seven years. The longwall began cutting coal in late February and is expected to produce more than 5 million tons of coal in 2012.
