The aveiage percentage of metallic tin is approximately 40 per 

 cent. 



There are at least four veins of major importance, varying 

 in thickness from one to two feet and over. They strike approxi- 

 mately north-north-west, south-south-east and have high dips. 

 They carry good values and are very micaceous in places. Origin- 

 ally work was done in open-cuts on the outcrops but as these became 

 exhausted the veins were followed downhill and opened up by cross- 

 cuts and drives. All the concentrates are won by hand and no 

 machinery is used. In the rainy season sluicing is carried on in 

 the detritals of the surface and on the dumps from the underground 

 operations. The beds of the streams at the bottom of the hill in 

 which the veins occur also carried gravels which were profitable 

 to work. 



Taunqpila No. 1 and No. 2.— North of the mine just described 

 lies the Tavoy Wolfram Co.'s Taungpila No. 1. while to the south 

 is the same concern's Taungpila No. 2. Both are held under mining 

 leases which date from 1915-16. The prospecting license of No. 1 

 (Ma SafiVs) was issued in 1912 and No. 2 (Una Kyi Pe's Pa in) 

 in 1913. 



Their production has been as follows : —
