20 HATCH : THE KOLAR GOLD-FIELD. 



chief supply of ore on the western or main branch of the lode. The 

 whole northern portion of the Tank Block property is now neglected 

 on account of the unsuccessful issue of earlier prospecting operations. 



The next property to the north of the Tank Block is the Coro- 

 mandel. The main work in this mine has b2en done on a chute some 

 300 feet long, situated in the northern section, and on a fold in the 

 vein about 100 feet south of the main chute. Although only 40 to 50 

 feet in length, the latter lias yielded a considerable quantity of good 

 ore, stopes on it having been from 10 to 16 feet wide. In the main 

 chute the stoping width is from 2 feet 6 inches to 3 feet and the 

 quartz is much intermixed with country rock. This chute goes into 

 the Balaghat between the 500 and 800-foot levels. Besides these 

 chutes a patch of ore some 400 feet in length and of irregular shape 

 has been developed in the southern portion of the mine on the supposed 

 extension of Kennedy's lode. Here the ore is largely mixed with 

 country rock and is consequently of low grade. In the central part 

 of the property, some 600 feet of ground which has been opened up 

 by levels driven from Prospect shaft, has hitherto yielded no pay-ore. 

 Future work in this mine will have to be confined for sometime to 

 come to prospecting operations with the view to locating chutes of 

 pay-ore. 



In the Balaghat Mine the main chute of ore is that developed by 

 Ogle's and Haine's shafts in the northern portion of the property. 

 The chute has a length of 600 to 700 feet which it maintains in depth 

 as far as developed, namely, to the i,o5o-foot level. The extension 

 of the 1,050-foot level south appears to have opened up a new chute 

 200 feet in length on the average and of good value. With regard to 

 width there is much variation from level to level, as the ore-body 

 has a marked lenticular character. Before milling a considerable 

 percentage of country rock has to be picked out from the ore on the 

 sorting floors. The Coromandel chute, west of the big dyke, is also 

 being developed on the south boundary, but as yet not much work has 

 been done on it. A small chute has been found on the lode opened 

 up by Tennant's shaft. Some good ore has been developed, but the 

 lateral extent of the chute hitherto proved appears to be small.
