All these veins carry good values, indeed the veins of the north 

 Mating Pok section yield better values than the others and hold out 

 more promise for systematic mining. Ground-sluicing is carried 

 on in all sections during the rains. 



Anya/pya. — This mine is held under a lease by Quah Cheng 

 Tock. It is the only working mine on the western side of the 

 Paungdaw capping and has veins both in granite and in the over- 

 lying sedimentaries, in two different sections of the workings. 

 Though small and rather irregular, they carry good values. Methods 

 of working are primitive and underground mining has hardly been 

 attempted. A long water-race and flume has recently been cons- 

 tructed to ground-sluice the detritals. The difficulty of trans- 

 port to the camp has always been a drawback to this area. 



The Melee Area.—Thioe miles beyond the edge of the Central 

 Intrusion, but associated with a small exposure of granite in the 

 Meke chaung, are the mines of the Meke area. These are leased 

 by Maung Ni Toe and Lim Kyi Yan, respectively. 



Ni Toe's Meke. — This mine was opened in 1911 and has produced 

 as follows : —

The vein concentrates only contain a little tin ore. In the case 

 of the material won from the detrital deposits the content is about 

 15 per ce it. Sn.
