side with, I believe, fair results. After washing off the alluvial he found 
the dyke beneath, and according to Mr. Wright’s report obtained a crushing 
which yielded 12 dwts. of gold per ton. Further crushings, however, gave 
very little over 6 dwts. per ton, and this was considered unpayable so 
the ground was abandoned. The report also states that a sample of stone 
dollyed from this lode gave concentrated pyrites equal to \\ per cent, of 
stone crushed, and on assay the concentrates yielded at the rate of 12J ozs. 
per ton. At the north end of the loam workings shown on plan the Happy 
Day lode was opened out on the surface for about 10 feet wide and 15 feet 
deep, and from this quarry Mr. Sheppard recently milled 5 tons which 
yielded about 3 dwts. of gold per ton. He also crushed 3 tons of mullock 
from the extreme south end of this line of workings near the mouth of an 
old fallen-in adit, and this gave 7 dwts. of gold per ton. At this latter 
point the lode is up 35 feet in width. There are numerous other workings 
to the south of this property and all are on similar formations.

SOME MINES AT BONEGILLA AND BETHANGA, NORTH¬ 
EASTERN DISTRICT.

Bonegilla. 
The Bonegilla Gold Mining Company’s workings, No. 1 locality, is on 
the west portion of allotment iia, section IX., parish of Bonegilla, on the 
side of a hill which rises about 90 feet above the alluvial flats. It is 
opposite to ana over haif-a-mile in a south-westerly direction from the 
junction of the Murray and Mitta Mitta Rivers. 
The country rock belongs to the highly metamorphic series which is 
so well developed at Bethanga and which continues from Bonegilla through 
the ranges of hills past Rat’s Castle and on to Indigo Creek, which 
appears to be its western boundary. This metamorphic series consists of 
schists and gneissose rocks which appear to be much older than the schists 
resulting from the local alteration of Ordovician rocks. They are of 
great economic importance as valuable mineral lodes are found to occur 
in them, such as those at Bethanga, and it appears highly probable 
from the manner in which the surface of the mineralized portions give little 
or no evidence of the presence of valuable ores below, that more careful 
prospecting may result in unearthing much treasure not at present suspected 
to exist in these rocks. The remarkable discovery at Kookimburra is 
a case in point, illustrating how little surface evidence exists of deposits of 
complex sulphide ores below. 
The rock at Bonegilla is gneissose and' very micaceous. At No. 1 
locality, in the side of the hill,'a cutting exposes ferruginous quartz veins 
from 1 to 6 inches thick, which cut through the country. They strike north 
and south and dip to the west at an angle of 32 deg. These veins are said 
to assay a few dwts. of gold per ton, and by learning colours of gold are. 
said to be obtainable anywhere over the surface.
