The average content of metallic tin in the detrital concentrate.-* 

 is about 25 pel cent. The content from the vein Concentrates is 

 about a quarter of this amount. 



The mine is divided into three sections: — (1) fjJast Kalataun". 

 (2) West Kalataung and (S) Thingandon. 'Hie l a tter includes the 

 sluicing grounds in the llteinthit valley. Both t,] lc others contain

Although many of the veins are in granite the tin content of 

 the concentrates is a low one, the average composition being 68 

 pel cent. WO, and 1 per cent, to 2 per cent, of metallic tin. 



On the lllanki Taung section of the mine, the name given to 

 the portion north of the main road, which runs right across the 

 lease, there are several veins from (i inches to 21 feet in width, 

 striking from north and south to north 30° east, south 30° west 

 and dipping easterly at 70°. The upper portion of the Hlanki 

 Taung hill is granite but the lower slopes have a covering of Mergui 

 sedimentaries. A large vein crops out in granite at the 6th furlon^ 

 of the 19th mile on the road side. It is here 3 to -1 feet thick and
