Hill 60 Group (Locality 65)

Surv., Canada, Memoir 159.

The Hill 60 group is at an elevation of 1,200 feet on the north side
of Bitter creck about 3 miles above its mouth. The development work
consists of open-cuts and an adit 300 feet long, and was mostly done before
1910. About 150 feet of the adit is a drift along the mineral deposit.

The country rock is black argillite and grey, sandy quartzite of the
lower part of the Hazelton group. A vein strikes northeast and dips north-
westward crosscutting the country rock at a small angle. It has been traced
on the surface for 250 feet; it disappears under drift at the southeastern
end, and apparently is cut off by a fault at the northeastern end. The
vein consists chiefly of quartz and brecciated argillite and is about 2 feet
wide on the average, but in one place underground it divides into parallel
quartz gashes and attains a total width of 9 feet. The vein is practically
barren of sulphides except for small shoots of chalcopyrite. The best body
of ore seen on the property is a lens of practically pure chalcopyrite 25
feet long and 8 inches wide at the widest part.

The holdings of the Independence Gold Mining Company are on
Fitzgerald creek. The mineral deposits are situated along a zone of
closely spaced quartz diorite dykes that invade volcanic rocks of the
Hazelton group and strike southeast across Bear River ridge and valley.
Several open-cuts and two long adits, one at an elevation of 2,950 feet
and the other at 2,760 feet, have been opened on a vein that parallels the
zone of dykes. The vein is at least 700 feet long and varies in width
between 2 and 25 feet, expanding and contracting greatly within short
distances. Several parallel veins, 2 to 6 feet wide, outcrop a few hundred
feet north of the large vein. The narrower veins lie mostly along contacts
between dykes and voleanic rocks. The veins contain sparsely dissemin-
ated galena, sphalerite, and pyrite in a gangue of quartz, barite, jasper,
and calcite. The chief value is in gold and silver.

Above the portal of the upper adit the large vein has been traced
for several hundred feet. Where exposed in No. 1 open-cut, 320 feet above
and 450 feet northwest of the portal of the adit, it strikes northwest. It
does not continue uphill on this line of strike because it is again exposed
100 feet to the north and 45 feet higher in No. 2 open-cut. In this open-
cut it has the same northwest strike and from the open-cut it can be fol-
lowed up hill for several hundred feet along this line of strike. The veins
exposed in the two open-cuts appear to be identical and are believed to
be parts of one vein offset by a fault passing between the two open-cuts.

The upper adit follows quartz stringers for 75 feet. It encounters a
wider part of the vein at 85 feet from the portal and follows this for 100
feet. At 275 feet from the portal it enters another large vein expansion
which it follows to the face a distance of 210 feet. The vein matter in
