worked by Mr. Atkins and his partner; it, also, appears to belong to the 
Newer Tertiary period; but there is quite 150 feet of difference between the 
level of this lead and the one to the west of Tanjil. 
Drifts of recent age occur in the flats, on the hanks of the Tanjil River 
and along the various gullies. When first worked thev are reported to have 
yielded gold in abundance, but there is a great lack of precise data. The 
alluvial gold is reported to have consisted Largely of extremely well water- 
worn pieces, and was in many cases of a coarse description.

Eureka Dykes. 
One and a half miles to* the north of Tanjil, on the western bank of 
the Tanjil River, there are two parallel dykes, 9 feet apart, named the 
Eureka dykes. They strike N.W., and dip 76 deg. to the S.W. These 
dykes are decomposed to a depth of 25 feet from the surface. Below 
that the material is hard and of bluish-grey colour. Quartz veins dipping 
W. occur in the dyke; they range up to 3 inches in thickness, and contain 
gold, but no authentic yields are known. From near the river bank 
tunnels have been driven along the dykes about 300 feet along the northern, 
and 150 feet along the southern, dyke. Several crushings are reported to 
have been taken from the tunnels, and there still remains the bed of a 
little crushing plant formerly employed on ore from the adits. Nearer the 
river is a shaft about 25 feet deep, and some rich returns are reported from 
some old workings close to this shaft. This lease is, it is understood, at 
present held by Mr. S. J. Pope and party. Across the river opposite the 
shaft is Barker’s reef, a quartz vein cutting across the sandstone beds. 
Its strike is N. 12 deg. W., and its dip 56 deg. E. The quartz is about 
8 inches thick, highly mineralized and hard, and quite unlike the quartz 
veins in the diorite dykes. So' far no gold has been got in this reef. 
On the Eureka dvkes and about 4 chains N.W. from the adit-mouth a 
shaft has been sunk 80 feet. Quartz veins are said to have been worked 
here, but with what result was not know r n. Dykes of this class appear to 
be very persistent, and are traceable for long distances; generally they are 
veined with quartz. No very determined effort appears to have been made 
to test them in depth, although they present similar features to those of 
Wood’s Point, from which phenomenally rich yields of gold have been 
obtained.

Westrop’s Reef. 
This reef is about ij miles N.N.W. from Tanjil. Its strike is N. 
n an< ^ dip 4 ° deg. W. The shaft is about 70 feet deep. 
I he thickness of quartz is not known. Payable ore is said to have been 
worked here for two vears.
