of pyrite was found on the refuse heap. This bed is said by Mr. Jas. 
Watts, acting mine manager, to have had a distinct influence upon the 
gold in the reef, for wherever the reef wa£ found in contact with it, the 
richest gold was present. The bed has not been struck in either of the 
mines to the south. 
The Tambakooka Beef. . 
This reef has been worked in the upper levels down to a depth of 
about 350 feet, viz., 330 feet in the levels, and 20 feet by underhand stoping. 
Some rich stone was obtained therefrom, according to information sup¬ 
plied to me by the company. The reef bears a little west of north, and 
underlies towards the west at about 27°, judging by the working of the 
stopes. The shoot of gold apparently pitches to the north on the northern 
side of the cross-course already alluded to. 
In the No. 1 (201-ft.) level, this reef lies east of the shaft, but cuts 
through it at the No. 2 (273-ft.) level, and has been stoped out for a con¬ 
siderable distance south of the shaft, and for a few feet north of it. At the 
cross-course referred to the reef was about 6 feet thick, but on being followed 
in a northerly direction it gradually narrowed, became broken and inter- 
laminated with strata, and finally, at the face of the drive, consists only of a 
series of thin veins, the main reef running underfoot. 
The same feature is noticeable in the eastern reef at the 273-ft. level, 
in the face of the drive going north from the end of the cross-cut east of 
the shaft. Here the reef was 6ft. 6iu. thick, with a well-defined hanging 
wall, but it runs out into a thin vein 3 inches thick at a point 36 feet 
-L 
north. 
The Groldsborough Company, however, is said by Mr. Watts to have 
worked a reef on this same hanging wall to a depth of 300 feet, and as that 
shaft is 248 feet N. of the New Birthday, it is only reasonable to infer that 
the reef resumes its ordinary character and thickness a little further on.

This same company, according to Mr. Watts, cut a reef 2ft. 6in. thick, 
supposed to be the Tambaroora, in a cross-cut west of its shaft, and though 
gold is said to have been showing, it was never worked. 
Now, as regards the characteristics of the reefs in the Queen’s Birthday 
mine, it is particularly unfortunate that, owing to the inaccessibility of the 
workings, no inspection could be made. It appears that the material that 
was stowed in the stopes between the Nos. 2 and 3 levels was allowed by 
the old company to fall through into the No. 4 level to act as filling for it, 
with the result that the ground gave way under a dam on the surface 
immediately overhead, and the workings were flooded with water and sludge, 
thus rendering their examination impracticable. All the conclusions arrived 
at, therefore, are based only upon such information as was obtainable locally 
from old plans of the company, from Mr. Watts, the acting mining manager, 
and from others who had worked in the mine. 
Down to a depth of about 420 feet, the eastern reef, ranging from 4 to 10 
feet thick, underlying east, and conforming to the dip of the strata, was lying 
against the same hanging wall as is found in the upper levels of the New 
Birthday mine, but at this point it took a roll and was underlying to the 
west, apparently in exactly the same way as shown in the winze between the 
404-ft. and 510-fit. levels in the New Birthday mine. In the 527-ft. level of 
the' old mine a quartz vein, 2 inches thick, is said to have been found against 
the wall, but at the 720-ft. level, in a cross-cut going east, the hanging wall 
without any quartz on it was passed through at 85 feet.
