a mineral zone found in the adit does continue to the surface it will, pre-
sumably, have a westerly dip and will outcrop well to the east of a point
vertically above its position in the adit.

Mineral deposits discovered in the Province tunnel were explored by
some 8,000 feet of tunnelling and by diamond drilling. A silicified zone
was encountered 1,650 feet from the portal. The zone is up to 400 feet wide
and has been followed by drifts for a length of 1,200 feet. It is in general
well silicified and pyritized and locally contains sphalerite, a little galena,
and more pyrite than the general average. The zone and the neighbouring
rocks are cut by numerous, narrow quartz veins and also by calcite veins
commonly striking about north. Among the youngest veins are veins up to
2 inches wide that can be followed for only 50 feet or less. Parts of such
veins carry much free gold. Some specimens show plates of gold an eighth
of an inch thick. These veinlets appear to be confined to the silicified zone.
They strike north to northwest and dip from vertical to 45 degrees south-
west. The veinlets consist of quartz banded with thin seams of chlorite. In
general the free gold is fine but locally is quite coarse. The narrow gold-
quartz veinlets are cut by black and white calcite veins. In the Province
adit two other silicified bands parallel the main one. They are less than 100
feet wide, more than 1,000 feet long, and are also characterized by narrow
quartz veins carrying gold.

The rocks in the adit are rudely stratified, voleanic fragmental rocks
that strike north to northwest and dip 45 degrees to 70 degrees westerly.
Individual beds cannot be followed far along the strike. They show con-
siderable variation in lithology and thickness. The silicified zones appear
to follow certain beds that apparently served as the best channels for the
ore solutions, perhaps because of their greater porosity. The value of these
deposits depends on the number and richness of the narrow gold-quartz
veins. To determine the value of the deposits, the silicified zones were
mined from the crosscuts, drifts, and from experimental stopes and the ore
produced was milled. The results of this test have not been published.

The holdings of the Bush Consolidated Gold Mines, Limited, consist
of the Border and Sunshine claims, Exchange group, Extenuate group, Start
group, Cobalt group, and Maple Leaf group. Most of this ground lies on
the east side of Cascade creek and Harris creek between Long lake on the
north and the Northern Light group on the south.

The Start group is at the northern end of Slate mountain. A quartz
vein locally 6 feet wide and mineralized with galena and sphalerite has been
followed about 200 feet by an adit. The Extenuate group is south of the
Start group. Mineral deposits discovered so far are of low grade. On the
Border claim on Cascade creek at the International Boundary a mineralized
zone in feldspar porphyry contains quartz, pyrite, and sphalerite. On the
Sunshine claim, south of Long lake, a sheared zone in tuffs contains very
sparsely distributed pyrite, sphalerite, and galena.
