To estimate the life of your proper-ties as a coal mining proposition is a difficult matter. Thereare several seams of coal on your properties, but for thepurpose of considering your life only the two seams at pre-sent being worked will be taken into account. On Ibisbasis we find that in the areas commanded by your presentpits it is estimated there are about 4,800 acres of coal-bear-ing ground of first-class quality, totalling about 70 milliontons of marketable coal. This alone even at the maximumrate of production of 120,000 tons a month, will last fornearly 50 years. Then, again, there is the area on Klipfontein adjoiningthe present Landau Colliery of 2,200 acres^ and the other onWolvekrans of 2,100 acres, both of which 1 have just referredto, in which the total can be put at about 52 million Landau Colliery: Trucks coming out of the Incline Shaft. To this must be added your other properties which eitherfrom a certain amount of boring or from their situation inrelation to proved areas may be considered as partiallyproved; these areas total about 21,500 areas, and on a con-servative basis max lie estimated to produce 104 milliontons. Lastly, there is the farm Bosmanspruit, in extent 7,059acres, under practically the whole pi which it is known thatthe coal measures exterid, but in regard to which in theabsence of any boreholes thereon or in the neighbourhoodno estimate of tonnage can be made. The total estimated tonnage contained in the companyspropeities, excluding Bosmanspruit, may be put at 280to 300 million tons, and this is without taking into accountthe other seams which run through your property, and whichwill some dav be of commercial value.
