18 HATCH: THE KOLAR GOLD-FIELD. 



average of 30 dwts. of fine gold to the ton. But in depth both width of 

 vein and gold-contents have diminished, and below the 1,620-foot level 

 the width of the ore-body is only from 2| to 8 feet, the average being 

 about 3 feet, while the grade of the ore is also lower. It remains to be 

 seen whether in the course of future developments these chutes will 

 open out again in depth as their lenticular character indicates they 

 may do. Separated by about 300 feet of barren ground from them is 

 the so-called South chute, which although of irregular dimensions has 

 yielded ore of high value. 



In the Champion Reef Mine the position of the chutes was also 

 indicated by extensive old workings which extended to an average 

 depth of 150 feet and to a greatest depth of 275 feet. There are 

 two chutes separated by a zone of barren ground where the vein is 

 pinched to a few stringers for a distance varying from 400 to 1,000 

 feet. The southern is the largest of these chutes. It is known as Gar- 

 land's or Gilbert's chute and extends on the 1,140-foot level (Garland's 

 shaft) from Dalyell's shaft to beyond Ribblesdale's shaft, a distance of 

 over 2,000 feet. More recent developments, however, have shown 

 that this was an exceptional length of chute ; for on lower levels 

 (1,240 and 1,340 Garland's) the chute has a length of from 1,200 to 

 1,500 feet. For a part of its length it is split into an eastern and 

 western branch by a " horse " of country rock. 



The northerly chute or Carmichael's carries a big body of ore 

 along the fold already referred to. On account of its great width 

 and the high-grade quality of the quartz it has been a valuable asset 

 to the mine. The fold appears to be dimin'shing in depth, but 

 although the stoping width is not so great, the ore maintains on the 

 whole its good quality. Present developments show that by reason 

 of its northerly dip this chute is rapidly passing into the property 

 of its northern neighbour, the Ooregum Mine, where it is being 

 opened up by levels driven from Taylor's shaft. 



In the Ooregum Mine old workings were found along the whole 

 length of outcrop extending to an average vertical depth of about 

 100 feet. The richer spots were followed down to greater depths, 

 the ancients going in one place as deep as 250 feet. Two chutes of
