Finlayson. — Scheelite of Otago.

The accompanying sketch section (fig. 2), along No. 2 level, 

 illustrates this feature.

Fig. 2. — -Section along No. 2 Level, Glenoechy Reef. 



The seam of quartz generally occupies the centre of the lode- 

 formation, being separated from the walls by a few inches of 

 pug. Frequently, however, the seam splits into two branches, 



leaving a horse of 

 country rock between 

 (fig. 3). 



The quartz is 

 seamed throughout 

 with thin parallel 

 strings of mullock, 

 highly pyritized. 



The reef carries 

 scheelite, not gene- 

 rally in very clean 

 patches, but more or 

 less quartzose. It does not cling particularly to either wall, 

 but is generally seen along mullock stringers. The bands or 

 seams of scheelite, though discontinuous, are fairly well defined. 

 The lode is auriferous, but its assay value for gold is very 

 small. 



Eecent prospecting in the Eees Valley and Bucklerburn 

 has disclosed other reefs carrying scheelite, some of which are 

 now being developed. 



Alia Reef, Bendigo. 



This lies at the head of a small gully just over the western 

 spur of Bendigo Creek, and about three miles to the east of the 

 old Bendigo battery. Its strike is 116°, and it stands almost 

 vertically, with frequent irregularities. The country rock is 

 a flat-lying quartzose schist, and the outcrop of the reef has 

 been proved for nearly half a mile.
