For this cross-cut there is therefore an average result of 11 dwts. to the ton. At this 
point the richest part of the reef is a band of the laminated quartz about two feet thick 
within a couple of feet of the footwall or underside of the reef. The average of this rich 
band is 22'68 dwts. 
Mr. Withers informs us that he has got almost as good results out of a shaft and cross 
tunnel which he made at the southern end of the outcrop, but that the reef is there narrower, 
about 9 feet in thickness. 
Hamsluck Reef .—About half a mile west of the high hill-outcrop of the Alpha Com¬ 
pany’s Reef overlooking Dayvallab village there is another strong lode cropping up in 
Mr. J. W. Minchin’s estate of Hamsluck. The lowest part of this reef, or what is seen in the 
bottom of the valley at its foot, is about three furlongs in length; and from this as base the 
reef slopes up the eastern side of a hill about 300 feet high. The strike of the reef is about 
the same as in others: the dip being about 20° to the eastward, though it is at a much 
lower angle on the summit of the hill. The known thickness of this reef is from 4 to 8 feet. 
The lode is cut off to the north by the dyke of green stone already noticed. It is traceable 
southwards into the Chullaymullay mountain, and probably runs under the northern end of 
Perseverance Estate. The eastern slope of the Chullaymullay alongside the latter estate has 
been perfectly riddled by the pits and excavations of the old miners who evidently worked 
at the side veins on the underside of the lode. Small samples of quartz were crushed, and 
gold was always got showing clear in every dishful of stuff; hut the result was small owing 
most probably to the presence of a great quantity of iron sulphide. Subsequent crushings 
gave the proportions shewn in the table. 
Dunbar and Balcarras Reefs .—About two miles further west, but on the northern 
side of the deep trench leading to the low country by Carambat, there is a good outcrop of a 
reef about 4 feet thick in the Dunbar Estate. Mr. Powell, the Superintendent of this garden, 
when down showing me the reef, was successful in knocking out pieces of quartz in which 
small streaks of gold were visible. The underside of this lode is very like in color and 
contents to that of the Alpha Company, the richer seam in the quartz being on this side. 
Leaders are numerous and large. The casing is of talcose schist, and seamed with ferru¬ 
ginous and manganese streaks. 
The lode is traeeable northwards into the Balcarras Estate, where there is a great show 
of white quartz on the eastern slope of one of the low hills. This part of the reef has been 
very extensively riddled by the old miners. In fact, all its extension northwards towards 
Pandalur has been washed, and its immediate neighbourhood on the underside is still a 
favorite locality for washing during the rainy season. It runs through the Elizabeth and 
Sandhurst Estates, and close alongside the Caroline and Mr. Holmes’ application, and thence 
northwards. 
My observations so far appear to show that quartz-crushing should be a success, in the 
Nambaly-code Amsham at any rate. Here, there are eighteen reefs 
aate° SI ’ eCtS ° f Wyn4d up t0 which are more or less auriferous in themselves, or as to their 
leaders. The leaders and underside of these are all known, or 
l-eported, to be auriferous with coarse gold; and it is probable that the great reason they 
are not worked now is that the pits necessary to be dug by the Korumbars would be too 
deep for their style of work, water being the great obstacle likely to be met with. The 
big reefs were not worked by these men on account of the difficulty of breaking up the 
stone, and because the gold is distributed too finely through it to have paid hand labor. 
With machinery and modern appliances, the reefs should pay even if only 3 dwts. of gold 
are got always from the ton of quartz.
