NORTH-WESTERN DISTRICT (No. 1). 43

occurring parallel to the bedding-planes. This is indicated by the development of gouge and
brecciated wall-rock in the vein-structure. Lamprophyre dykes up to about 6 feet wide, and
a diorite dyke 80 feet wide, which is probably a spur from that outcropping along the railway-
track, are intrusive through the vein.

_The deposit has been explored by surface cuts, about 450 feet of tunnelling, and a 40-foot
raise to the surface. Small shipments of selected high-grade ore have been made. The closely
sorted ore shipped assayed: Gold, 0.27 oz. to the ton; silver, 806.4 oz. to the ton. The lower-
grade shipping-ore assayed: Gold, about 0.16 oz. to the ton; silver, from 80 to 180 oz. to the
ton. As an individual operation, without the burden of overhead expense, close selective mining
may yield some profit.

This property is located at about 2,000 feet altitude on the north-east slope of
Alice Arm-La Rose Haystack mountain. A detailed description of the property and workings is

Mining Co., Ltd. contained in the 1928 Annual Report. The vein, from a few inches to 3 feet

wide, occurs in the argillites that cover the slope of Haystack mountain to
about altitude 1,925 feet, where they appear to abut on the underlying voleanics which form
the upper slopes of Haystack mountain. The bedding of the argillite strikes approximately
N. 50° W. (mag.) and dips easterly towards Kitsault valley at about 45°. This structural
condition seems to have a very important bearing on the economic attitude of the La Rose vein.
Mineralization consists of galena, sphalerite, grey copper, pyrrhotite, pyrite, arsenopyrite, some
native silver, and possibly argentite and ruby silver, in a quartz gangue.

Disappointing results have been met with on the No. 1 tunnel-level at altitude 1,900 feet in
the argillites, and the prospects for improvement in the downward extension of the vein in this
formation are not encouraging. It is evident, however, that where the high-grade ore was
struck in the raise, about 20 feet up from the tunnel-level and from there to surface, it is either
iz, or very close to, a tuffaceous rock, heavily impregnated with pyrite and an undetermined
black mineral. Again, in the upper tunnel near the- mouth of the shaft at altitude 2,060 feet,
the vein is contiguous to this tuffaceous rock and shows fair mineralization until it enters the
argillites proper, when it immediately becomes shattered, sheared, and barren. A sample of
the tuff rock accompanying the ore-shoot, showing a fine dissemination of pyrite, pyrrhotite,
and small crystals of mispickle, assayed: Gold, 0.08 oz. to the ton; silver, 23.8 0z. to the ton.
As this represents wall-rock, not the vein, it is an interesting indication.

The property has been inactive during the year. More work is, however, certainly warranted
to determine the extension of the vein in the apparently ore-making tuff. This would best be
accomplished initially by lateral development in both directions from the intermediate drift.
The ore where it does oceur is high grade and, as it appears to be associated with the contiguity
of tuff and as the yein is strongly developed in that locality, the policy of determining the
attitude of the tuff in its relation to the vein is well warranted. Further exploration could then
be planned from the result of this work. Between 1918 and 1927, 79 tons of ore was shipped
from this property. This returned: Gold, 15 0z.; silver, 15,579 oz.; lead, 2,688 Ib.

This group of claims is owned by W. McFarlane and associates, of Alice Arm.

Homeguard. It is situated on the east side of the Kitsault river, about 14 miles from Alice

Arm. The ore-showings have been thoroughly described in the 1922 and 1924
Annual Reports. The property is under option to the Dalhousie Mining Company, Limited.
During the year the claims were prospected by a Radiore electrical survey. The results of this
survey are not known. It is understood that two additional discoveries of promising ore were
made on the property during the latter part of the season.

This property of eight claims, together with the Wolf group of four claims,

Dolly Varden. originally owned by the Dolly Varden Mines Company, Limited, was optioned

by the Britannia Mining and Smelting Company, Limited, late in the 1929
season. The ore occurrence and workings are described in the Geological Survey of Canada
Summary Report, 1921, Part A, and in the 1916, 1917, and 1922 Annual Reports. During the
somewhat hectic high-grading operations on this property from 1919 to 1921, a period of high
silver price, 36,620 tons of ore, carrying about 86 oz. of silver to the ton, was shipped from the
property. Very little development ahead of production was carried out and an operation that
offered good promise came to an untimely end.

Former diamond-drilling and limited exploration on both the Dolly Varden and the Wolf
groups indicates the possibility of developing an appreciable tonnage of mill-grade ore. The
