§ Mr. Grimond
asked the Secretary of State for Trade and Industry what is the oil equivalent of the estimated reserves in recently discovered but untapped coalfields.16W
§ Mr. Tom Boardman
Responsibility for exploration and proving of reserves rests with the National Coal Board, which has recently commenced a greatly expanded programme of exploration. The estimation of workable reserves involves extensive borings and geological studies, and realistic estimates cannot be made till these are completed. I will write to the right hon. Member when further information on recently discovered reserves is available.
