In addition to tliis work in the levels already opened up, sinking 
tke main skaft will probably open up new bodies of payable stone. 
As tbe shaft is already down to 802 ft., a new level at 800 ft. could 
be driven without much sinking, giving 180 ft. of backs below tbe 
ISTo. 5 level. 
Yields. 
The quarterly returns of the mining registrars give a total of 30,667 
tons crushed for 9,507 oz. of gold from the Golden Bar and Yo. 1 reefs 
up to December, 1900, an average of 6.2 dwt. per ton. Brom tbe ISTo. 2, 
or Alfred, reef, tbe records give a total of 1,842 tons crushed for 1,114 
oz. of gold, an average of 12.1 dwt. per ton. These records are incom¬ 
plete, tbe first, and probably best, crusbings not being included. To 
tbe end of 1910 the Cbiltern Golden Bar Company crushed 23,251 tons 
for a yield of 12,453 oz. 9 dwt., an average of 10.7 dwt. This gold 
has been won almost entirely from tbe Yo. 1 reef. 
Tbe mine is equipped with winding and crushing plant. Tbe ore 
is free milling carrying gold, pyrite, and arsenopyrite. A new battery 
has been erected, but want of funds has delayed its completion. When 
finished it will permit of low-grade ore being mined at a profit, which 
cannot be worked at present.

THE LADY ROSE MIYE, CHILTERY. 
By J. P. L. Kenny, B.C.E., Assistant Field Geologist. 
Tbe Lady Rose Mine lies to tbe north of tbe Golden Bar and Golden 
Bar Extended mines, and is working tbe same belt of auriferous country. 
Four lines of reef outcrop in the lease, namely, tbe Yo. 1 reef, tbe 
Cellar reef, tbe Lady Rose reef, and tbe Railway reef, in that order 
from east to west. 
Tbe Yo. 1 reef, which outcrops 210 ft. east of tbe Lady Rose shaft, 
carried good stone further south, furnishing most of tbe gold won by 
tbe Golden Bar and Golden Bar Extended companies. Just to tbe 
south iof tbe Lady Rose lease boundary a shoot has been worked on 
this line from a shaft known as tbe Gift shaft, and said to be 180 ft, 
deep. A drive from tbe Golden Bar Extended Company’s shaft was 
put out towards these workings, at the 400-ft. level, and intersected a 
slide dipping w^est. This slide would cut off the reef at a depth of 
about 350 ft. Tbe reef above this depth and below tbe old workings 
has not been prospected. The slide has not been seen in tbe Lady Ro*se 
Mine, but it will probably be met with at a deeper level than tbe 
present workings. A cross-cut, now filled in, at tbe 93-ft. level in tbe 
Lady Rose Mine is said to be out 180 ft. east, and it probably cut tbe 
Yo. 1 reef.
