CALCULATION OF MINEABLE RESERVE BASE, CAMEO "B" SEAM
• The mineable reserve base for the Cameo "B" seam is the same as the coal
reserve base, since all the coal in the "B" seam in the lease area is considered
commercially mineable.
CALCULATION OF RECOVERABLE RESERVE BASE, CAMEO "B" SEAM
The recoverable reserve base was calculated using a 50% recovery rate.
Equation used to calculate recoverable reserves:
(Area in Acres) x (Avg. Thickness of Seam) x (90 lbs/ft 3) x
( 1 To, ) x (50%) = Tons Recoverable
2000 lbs
Estimated recoverable reserves for the Cameo "B" seam in the lease area:
CALCULATION OF COAL RESERVE BASE, CAMEO "C" SEAM
The coal reserve base in Lease No. C-078049 for the "C" seam was calculated
using information from four drill holes.
Equation used to calculate coal reserve base:
(Area in Acres) x (Avg. Thickness) x (90- lbs/ft 3) x ( 1 Ton ) = Tons
