MINES OF THE BOLJNTAUNT.-BYAUKCHAUNC RANGE. 275 



Maung Sein Rhine's Ziriba. — This mine adjoins Steel Bros, on 

 the east and reaches up to the frontier. The workings are near 

 the boundary with Steel Bros, and are really part of the same 

 deposit. In 11)17 it produced 4 cwts., and in 1918, 13 tons. There 

 is a small prospect to the south of Sein Rhine's mine known as 

 Ethe chaung and licensed to Khoo Zun Ni. It produced over 2 

 tons in 1917 and 2 tons in 1918. 



The Kaleinaung Intrusion. 



This is a long narrow lobe of the Frontier Range intrusion 

 and its eastern boundary follows the north and south portion of 

 the course of the Zinba chaung. Various prospecting licenses have 

 been taken up in and around it for a number of years but up to 

 date it has yielded nothing of importance. From an area known 

 as Pa wave near its eastern boundary and close to the .stream itself, 

 Messrs. Booth and Milne extracted 3 tons of concentrates in 1918. 

 Their area formed part of a larger one originally belonging to Shwc 

 (Joe, who extracted a somewhat larger quantity from it. 



The IJolintaung-Byaukchaung Range. 



This is built up of a lobe of granite from one to three miles 

 wide which runs in a north-westerly direction for seven miles from 

 the Bolintaung peak; joining the main Sinbo-Sinma massif. The 

 latter, although one of the largest expanses of granite in the district, 

 contains only one or two mines and is now reserved for a cinchona 

 plantation. The Bolintaung range is breached by the Talaingya 

 river. Practically the whole of it is covered with mining areas 

 and on the south the surrounding country too is given out in small 

 concessions, none of which produce any large quantities of ore. 

 They are, with few exceptions, small native-owned concessions 

 worked on hand to mouth principles. 



Bolintaung. — One of the important exceptions, where development 

 is being undertaken systematically, is Messrs. Bulloch Bros.' Bolin- 

 taung area, which lies on the eastern side of the main steep 

 intrusion, which is here about a mile across and culminates in a 

 peak 1 ,000 feet above sea level. It forms part of a large area 

 which in the early days of the field was held by The Burma Malaya 

 Co.. Ltd., and in which Mr. Page recorded 7 veins varying from h 

 to 2 feet in thickness in 1912 or 1913. The following data are from
