North from the cross-cut a level has been driven 105 feet on the reef, 
which dips 80° W., cutting beds dipping 80° E. The quartz is from 6 inches 
' to 1 foot in width, and carries pyrites, and as in the upper level has a well- 
defined hanging wall. 
At 90 feet north of the cross-cut prospects of gold were obtained in a 
9-in. vein of quartz, ahd this was risen on for 6 feet, but did not improve. 
.At 32 feet north of the cross-cut a dyke rock dipping 45° N.E. was cut, 
and this may be continuous with the reported dyke cut at 370 feet in the 
shaft, which would pass just below the point at which the quartz block cut 
out in the winze. ( 
A rise north of the cross-cut connects with the winze from the 330-ft. 
level. 
A level south from the cross-cut has been driven for 128 feet, and a cross¬ 
cut from its south end extends east 1 28 feet, exposing hard sandstone and 
quartzite beds with some narrow beds of slate dipping 80° E. and carrying 
some quartz spurs. Along this south level the reef seems somewhat disturbed, 
and makes a roll to the east, the beds also dipping east. The strata are 
sandstones and quartzites, with narrow slate beds all dipping to the east at 
an angle of 80°; in the south cross-cut the slates are slightly more frequent. 
This points to more slates occurring to the east, as might be expected. 
Genekal Aspect. 
The developments since the last report show that the beds passed through 
are hard sandstones and quartzites with narrow beds of slate, and, therefore, 
the conditions have not been favorable to the occurrence of large reef 
formations and spurs of quartz similar to those worked above the 200-ft. 
level to the surface, where the slate beds predominated and the reef channel 
was wide and associated with large footwall spurs of quartz. 
In my opinion, the auriferous quartz at the 330-ft. level should be further 
prospected by following the stone downwards on its northern pitch, besides 
following it above the winze, which is the policy of the present management. 
Further driving north at the 400-ft. level may cut other blocks of quartz 
on the pitch north from the one now being worked at the 330-ft. level. 
As the series of western-dipping slates to the east, which accompany 
Scotchman’s reef, has not yet been met with, further sinking is advisable, as 
the larger formations with quartz spurs cannot be expected until this second 
series of favorable slate is met with as it folds under on the syncline.

PATTEN’S MINE, BROWN’S REEF, EVANSFORD. 
By 71. S. Whitelaiv, Field Geologist. 
Brown’s reef, about 1J miles north of Evansford, is evidently a leg on 
the western side of an anticline striking nearly north and south. It was 
discovered about forty years ago, and was then worked with payable results 
for a length of about 60 feet and to a depth of about 30 feet. Later, a 
party of local farmers took it on tribute and worked it down to about 40 feet 
for yields which returned about £1 per week per man. About, two years 
ago the present holders obtained a lease along it and sank a vertical shaft 
to a depth of about 95 feet at the end of the old workings, with which, for 
ventilation purposes, a connexion was effected at a depth of about 30 feet. 
The reef at about 84 feet from the surface passed through the shaft. At
