two mines and two companies

Just curious but does cpl have enough coal and a possibility of substantially more undiscovered coal to split into two. Tout one half as being for sale while building the other half up to similar reserves; eventually to go on the market. The combined sale price if sold separately could possibly far exceed a single sale price. This would be quite a common thing to do where a Co had reserves of two different comodities; ie spin or hive off one commodity into a separate Co. Is this a feasible thing for cpl to do?? cheers jwt
