20 deg. N., and its dip 65 deg. northward. All the four reefs in this 
lease are parallel, and they all dip in the same direction. The cost of 
driving the lower adit is about 25s. per foot, and the rock now being cut 
through is a favorable-looking slate.

THE GOOD HOPE REEF, GRANT. 
(NO. 16 ON LOCALITY MAP.) 
By E. J . Dunn , F.G.S., Director , Geological Survey. 
This reef is situate about 4 miles from Grant in a westerly direction^ 
The strike of the reef is about N.W., the dip is nearly vertical, and the 
pitch of the shoots of gold is eastward. The reef is from 2 to 4 feet 
thick, but for considerable distances along the “channel” or course of 
the lode there is no quartz, beyond an inch or so, as proved in the deep 
level adit. 
Formerly the reef was worked from adits. No. 1 adit is on the western 
side of a ridge, and has been driven S.E. along the course of the reef, 
which is here 1 ft. 2 in. thick. At 120 feet, the reef takes a turn south¬ 
ward. The strike of the reef is N. 20 deg. W., and the dip vertical. 
The height above sea-level is about 3,000 feet. Very little work has 
been done in this adit. 
No. 2 adit was driven from the southern side of the spur, about 250 
feet further to the east than No. 1, and lower down the hillside. It is 
430 feet long, and a considerable amount of quartz was obtained from it. 
No. 3 adit has also .been driven from the southern side of the spur; 
it is about 100 feet further to the east, and considerably lower down the 
hillside than No. 2. It is 728 feet long, and from it the reef was exten¬ 
sively worked 1 . 
No. 4 adit is about 700 feet below the outcrop of the reef at No. r 
adit, and is 500 feet further to the east than No. 3. It is 1,112 feet 
long. The level at the end of the adit has been driven along the reef 
for 730 feet, and for a distance of 520 feet was in payable ore. Three 
winzes have been sunk below this level to a depth of 50 feet, and the reef 
was stoped. Underfoot the auriferous reef continues, and 1 Mr. Noble, 
the manager, informed me that an average bulk sample along the whole, 
length of the shoot gave a return of 17 dwts. 4 grs. of gold per ton of 
ore, as broken out. This is the lowest point at which work was done on 
the reef. The further exploration of the lode could be most quickly 
effected if an electric plant were erected to the north of No. 4 adit. 
On the opposite side of the valley is the Uncle Tom reef, from which 
a small quantity of quartz was taken and crushed. Lower down the creek 
alluvial gold has been worked extensively. From the old workings, Mr. 
Noble informed me, 14,461 tons of quartz were crushed, yielding 23,357 
ozs. of gold. The concentrates were rich, in some cases averaging up to 
31 ozs. of gold per ton. 
With the object of picking up the shoot of gold going underfoot at 
No. 4 adit, and also of exploring the “ channel ” of the reef for other 
shoots of gold, a low-level adit has been driven in from the western end 
of the reef. The mouth of this adit is about 600 feet below the level of 
No. 4, and 2,000 feet to the N.W. of No. 1. The adit is 6 ft. by 5 ft. 
in the clear, well timbered, and driven in' hard country. The country-rock
