in the mine are two “floors”; these are movement plains carrying quartz 
veins, which extend across the dyke from east and west, and pitch N. 10° W. 
at about 20°. In one of them there is an inch or two of pug or kaolin. The 
quartz ranges up to 1 foot in thickness, and above and below the floors small 
quartz leaders irregularly intersect the dyke-stone and form a stockwork. 
It appears as though solutions have deposited auriferous quartz in and close 
to the fissures, and also to a less extent throughout the dyke-stone. The 
main floor reaches the surface a few feet south of the south shaft, and it has 
been proved to a depth of 70 feet at the bottom of the 70-ft. shaft, a distance 
along the pitch of 115 feet. From an inclined drive crushings have been taken 
out along this floor, and also easterly and westerly along the 70-ft. level. *It 
is stated that the ore was taken out for a thickness of 5 feet in places. 
Several crushings yielding 15 dwt., 1 oz., and 2| oz. to the ton have been 
obtained. A small crushing from above the roof of the upper floor yielded 
17 dwt. to the ton, and 200 tons have been crushed for an average of 1 oz. 
15 dwt. of gold to the ton ; one small very rich crushing was obtained. The 
north and south reef gave up to 7J oz. of gold to the ton. As the manager 
was not at the mine, complete details of crushings were not obtained. It 
is considered from the results of the various prospecting operations that there 
is a portion of the dyke upwards of 50 feet thick, pitching north and inter¬ 
sected by quartz floors, veins, and leaders carrying gold, which, with proper 
machinery, would pay to work. On the dump there was nice gold in quartz 
leaders in the dyke stone as well as in the quartz in the roof at the 70-ft. level. 
The north and south reef is about 2 chains west of the shaft on the dyke. 
It- is not opened up much, but a vertical shaft has just been*started on it. 
At the surface south of the shaft it carries about 1 foot of quartz, and in the 
shaft it appears to be dipping with the country rock to the east. There is no 
machinery on the mine, and the shaft is being worked with a windlass. 
The dyke has been proved auriferous to a vertical depth of 70 feet, and 
the payable floor extends across the dyke upwards of 100 feet. 
There is both low-grade and rich ore in the mine. It would not be wise 
merely to follow the latter, but the property should be thoroughly proved, 
and then suitably equipped to deal with all the payable auriferous ore. Timber 
is abundant, and Potter’s Creek flows just below the mine. 
The dyke is said to have been traced for many miles north and south of 
the mine, Abel’s mine, 2 miles to the north, being mentioned as one of the places 
where it has been located. On searching the spot mentioned grit bands were 
found, but no dyke. Similar rock is well developed at Blackwood and 
Blakeville, and has been noted at Bocky Lead, Steiglitz, and other places. 
It has been formed from the breaking down of granite, and is composed of 
grains of quartz and felspar up to J of an inch in diameter. This rock has 
frequently been confused with a quartz-porphyry dyke-stone, but the grit 
bands contain more quartz grains than the dyke-stone and have less base ; 
they also contain grains of black quartz and an occasional fragment of slate- 
If the decomposed grit be rubbed between the hands and panned off, the 
residue will consist of coarse sand and larger well water-worn quartz grains. 
The dyke should be traced as far as possible north and south, and it is 
very probable that other quartz-porphyry dykes may be found in this country, 
for at Bocky Lead, about 8 miles north-west of Blakeville, there is one of the 
same series of dykes from which a little gold has been obtained. 
The workings at the Golden Hope mine illustrate how important it is that 
prospectors should thoroughly loam and otherwise prospect any dyke met* 
with, for, throughout the State, many of our gold occurrences are associated 
with dykes of one sort or another. The Victory dyke at Foster, from 'which
