discovered by Mr. F. C. Cliff about sixteen years ago. In width the re'ef 
ranges from 1 foot to 3 or 4 feet wide, and it cuts through beds of highly 
indurated sandstone, slate, and conglomerate. Near the reef the conglo¬ 
merate is intersected by quartz veins, that traverse the pebbles as well as 
the matrix. This is a case in which pebbles have become veined with quartz 
after they were well rounded. Pebbles formed of rock through which quartz 
veins run are common enough in many streams, but pebbles in which quartz 
veins have formed after the pebbles had been rounded are less frequently 
met with. 
There are direct evidences of metamorphic action in this mine, as the 
sandstone is altered into hornfels of dark-grey colour, and the conglomerate 
is highly indurated. At the surface the conglomerate is soft through decom¬ 
position. The pebbles in it exhibit much shearing. The alteration in the 
Silurian beds has no doubt resulted from the presence of granite rock below, 
as outcrops of that rock occur both to the north and to the south. The 
conglomerate bed can be traced for miles. 
The first crushing from the reef consisted of 20 tons, and it yielded 
126J oz. of gold worth £3 18s. per oz. The shaft is 90 feet deep, and at 
80 feet a cross-cut was driven east for 80 feet to the reef. From the surface 
the shoot was worked to 80 feet and than abandoned, as water-level was 
reached. On the south side of Glen Creek a shaft has been sunk 70 feet, 
with the object of picking up the Bonnie Doon reef, but it was not reached.

THE LUCKS ALL GOLD MINE, ENOCH’S POINT. 
By O. A. L. Whitelaw , Field Geologist. 
A 
The Lucks All mine is situated at the head of Warner’s Gully, in which 
is a small creek about 1J miles in length running into the Big River from the 
western side, about 2 miles south of the township of Enoch’s Point. It is 
reached by pack-horse track, and is about 4 miles from Enoch’s Point. 
This mine was discovered in 1868 by Mr. Warner, a prospector, while 
tracing the alluvial gold in the gully to its source. The dyke “ bulge ” or 
“ basin ” is typical of those occurring in the Walhalla, Matlock, Wood’s 
Point, and Gaffney’s Creek belt, such as have been worked in the Loch 
Fyne, Morning Star and Hope, Al, and Star of Erin mines. It differs in 
one respect, however, in that the dyke occurs in sedimentary rocks of older 
age than the Walhalla series of rocks ; they are probably of Lower Silurian 
or Ordovician age. 
The Lucks All dyke-bulge, which contains the numerous reefs worked, 
is about 200 feet in width by 700 or 800 feet in length. The strike is N. 
48° W., and dip about 65° S.W. The reefs have the usual characteristics of 
the occurrences in the dyke-bulges ; they strike across the dyke between 
the eastern and western walls, and dip along the length of the dyke. The 
Lucks All reefs occur one below the other in more rapid succession than 
those of other local mines, and with one exception fall from the slates at the
