It is shown that in an area around Mamabule railway siding in the Bechuanaland Protectorate two principal seams of medium-grade, non-coking bituminous steam coal are developed at shallow depths in the arenaceous Middle stage of the Ecca series. The quality and resources of coal are evaluated from the results of boreholes and shafts. Tables of analyses are presented. Total reserves of coal within a defined area 17 square miles in extent are estimated to be 408 million tons.ย
