Mines of the Coastal Range. 



The greater part of the Tavoyan coast line is foimed by a high 

 granite ridge which rises from the sea a few miles to the north of 

 Ye in the Amherst district. It is breached by the Ye river, crosses 

 the Malwedaung range, forming the northern boundary of the 

 district, at an elevation of about 2,800 feet and then continues 

 south. 



Medaw Kanbay. — The wolfram mine of Medaw Kanbay, the 

 property of Maung Ni Toe, is situated on its eastern flank a. few 

 miles north of the point where it is breached by the narrow tideway 

 known as the Heinze Basin. This mine was opened in the year

The concentrate is a high grade wolfram practically free from 

 cassiterite. It comes from a peculiar flat quartz vein which crops 

 out at intervals around the periphery of a group of hillocks, and 

 varies in thickness from 1£ to 3 feet. It is often divided horizon- 

 tally into two or three portions by thin layers of the country rock, 

 which is an argillitc of the ordinary type. Granite occurs in the 

 high range to the westward and is said to have been met with in 

 the deeper exploratory shafts below the vein. There is some 

 evidence that the vein begins to dip towards the south in the most 

 recent workings, and that it may be found to conform more to the 

 general type as they extend. There are also a few small normal
