THE LODES, jg 



ore have been worked : the southern chute, developed by Wallroth's 

 and Taylor's shafts, and the northern by Probyn's and Low's. On 

 the upper levels the southern chute had a lateral extent of close on 

 i, 800 feet, and the northern, of about 900 feet. Below the 760-foot 

 level the southern chute has not been found to have the same extent 

 as on upper levels as will be seen in the section (PI. 9). It 

 is just possible, however, that the development work has been done 

 on a poor branch of the lode, the pay-ore being perhaps confined to 

 an eastern branch, which has not been explored. Near the southern 

 boundary a valuable chute of ore has come in from the Champion 

 Reef property, and in depth every successive level has developed a 

 greater extent of it. The i,6io=foot level, as far as at present 

 driven, has developed 1,000 feet of good ore having a stoping width 

 of 4 to 5 feet. In consequence of these chutes coming in from the 

 Champion Reef, the prospects of this mine are certainly encourag- 

 ing. 



On the other hand the best portion of the northern or Probyn's 

 chute has passed into the Nundydroog property. This chute which 

 has an average length of about 500 feet has been extensively devel- 

 oped in that mine, the ore-body being in places of considerable size, 

 namely, 8 to 20 feet, although the average width probably does not ex- 

 ceed four feet. Between this chute and the one next to the north, there 

 is in the Nundydroog Mine about 1,800 feet of unprofitable ground. 

 Then comes Kennedy's chute, which in the best place (on the 370-foot 

 level) had a length of 1,300 feet, the ore-body averaging from 4 to 5 

 feet in width. Lower levels have not developed as much pay-ore on 

 this chute. The best portion, in which a thick deposit of quartz along 

 the axis of a fold in the vein gave stopes up to 30 feet in width, has 

 passed above the 440-foot level into the Tank Block Mine. In the 

 latter mine work has for sometime been practically confined to the 

 development and stoping of the ore contained in the thick part of 

 the fold, and in a branch given off from it, which, after first dipping 

 to the east, runs flat for about 50 feet and then pinches out (see 

 section). It is a valuable chute of ore, but being of small lateral 

 extent does not yield a large supply. The mine must depend for its
