The Sunrise group of eight mineral claims occupies part of the
southern slope and part of the flat top of McGrath mountain. The group
adjoins and lies north of the Standard group and is reached by the
McGrath Mountain trail. The property was acquired by the Kitsault
Eagle Silver Mines, Limited, in 1928, and this company carried on active
development in 1928 and 1929.

The country rock consists of argillite and associated coarser grained
sediments striking north. The sediments have been intruded by an
irregularly shaped stock of augite porphyry and by a number of dykes.
The mineral deposits occur in fractured and brecciated zones and also
as clear-cut veins in the argillite.

Many open-cuts have been made and an adit 1,000 feet long has been
run, but they fail to prove any connexions between the scattered showings.
The veins strike north and have steep dips. They are 1 to 6 feet wide
and consist of quartz and some calcite and sphalerite. Wider deposits up
to 20 feet wide formed probably in brecciated zones consist of quartz,
calcite, sphalerite, and fragments of country rock. One of these bodies
appears to be nearly horizontal, another appears to dip north about 30
degrees. It is likely that faults with small throw are numerous.

Sunset Group (Locality 190)

The Sunset group of seven mineral claims is on Roundy creek about
2 miles from Silver City. The property is reached by the Roundy Creek
trail. The group in 1923 was taken under option by the Keystone Mining
Company.

The rocks on the group consist of argillite intruded by the Coast
Range batholith. The mineral deposit lies very close to the contact. It
is a quartz vein striking south-southeast and has been traced for several
hundred feet. The southern part of the vein lies in a granitic rock but
the northern part is in argillite. The vein is mineralized with pyrite,
galena, and sphalerite and locally contains good silver values. An adit
600 feet long has been driven under the surface showings but did not
enter the vein.

Surprise Claim (Locality 147)
Reference: Annual Report of the Minister of Mines, British Columbia, 1916.

The Surprise claim is east of Kitsault river. It is 16 miles from
Alice Arm and adjoins and lies east of the David Copperfield claim.
The mineral deposit is a zone 25 feet wide, striking east, and traversed by
stringers and veins of barite and quartz that constitute about 75 per cent
of the zone, but it appears to be barren of sulphides.
