There are two districts in the concession which produce wolfram. 

 viz., Pathan Hill and Maung Pok Hill. In Pathan Hill and its 

 vicinity the mean strike is north 60° west, south G0° east, with a 

 dip of about G0° to the north-north-east. It is to be noted however 

 that several of the veins, and especially Nos. 1 and 9 have, for 

 short distances, strikes differing several degrees from this. These 

 veins at the bottom of the hill are in hard argillites and have thick- 

 nesses of from \\ to 3| feet, but further up and nearer the surface 

 they have split up and formed numerous smaller veins varying from 

 4- to 10 inches in thickness. Some of these thinner veins have 

 been followed for several hundreds of feet and occasionally right 

 through the hill to the other side, but most of them have a tendency 

 to thin out and disappear after reaching the heart of the hill. The 

 vertical distance between the highest and lowest workings in this 

 hill is 280 feet. Faults of any magnitude are unknown, and the 

 small ones which do occur are normal. 



The Maung Pok Hill is of granite and attains an elevation of 

 some 4,000 feet above sea level. On the south face, about 900 

 feet below the summit, numerous veins crop out, while a few small 

 ones are found at points higher than these. They are either vertical 

 or dip very steeply, up to 85° to the east, the strike being north 

 and south. There are no notable departures from this rule. The 

 thickness of the veins varies from two inches to one foot six inches. 

 but they all possess the property of diminishing in width and value 

 as they are followed into the hill until they practically disappear. 

 This occurs at a distance of about 80 feet from the portals of the 

 drives. On the north side of the hill there is a considerable change. 

 The veins strike nearer east and west. They are either vertical
