(50 b) Black Prince No. 3, Uchucklesit Harbour
(See Figure 41)

Another small, isolated deposit of magnetite occurs on the Black
Prince No. 3 claim, at an elevation of 2,000 feet (barometric) on the top
of the mountain, about 14 miles north-northeast of Kildonan, Uchucklesit
harbour, and may be reached by a good trail leading from there. The
summit of the mountain in the vicinity of the claim is somewhat flat
(drift-covered) and is clothed with balsam, hemlock, and moss.

The Black Prince No. 3 is a claim of record, belonging to James
Wilkenson of Alberni, and the required assessment work is carried out
from year to year.

Six separate masses of pure and rocky magnetite occur throughout a
longitudinal extent of 200 feet in a northeasterly direction, but the largest
of these individual masses has an exposure of only 250 square feet (Figure
41). They are of irregular shape and occur in association with a fine-
grained, cherty, porphyritic andesite or andesitic tuff, near its contact
with intrusive hornblende diorite. Two bodies of high-grade, lustrous,
granular magnetite occur. These are strongly sheeted, with sheets from
13 to 2 inches thick, have a sugary texture, and in many places possess
polarity (lodestone). Some of this solid variety is tarnished blue by
copper minerals, and has the closely spaced joints filled with veins of
pyrite. The more impure masses are intimately mixed with porphyrite or
occur as veinlets in it, and contain disseminated garnet.

There is no evidence of limestone on the claim, although at a distance
of several hundred feet down hill towards Kildonan, and continuing from
there to the shore are extensive exposures of massive grey limestone. It
is Just possible, however, that the slight depression between rims of diorite
trending southwest from the main showing is underlain by limestone, and
that such an inclusion of limestone is replaced by magnetite and cinnamon-
coloured garnet. It seems more plausible to consider that the porphyrite
belongs to the Vancouver series, and that veinlike masses and irregular
bodies of magnetite have been deposited in it, by contact action of the
Beale diorite.

Two small open-cuts constitute the development work, but they do
not assist materially in proving continuity of the magnetite. No estimate
of tonnage can be made, and the deposit is of no commercial value.

(50 c) Sunshine Group, Uchucklesit Harbour

Another small deposit of magnetite occurs on the Fern claim, of the
Sunshine group, located on Cascade creek, which flows into Uchucklesit
harbour at Kildonan (Wallace Fisheries plant). The showings are about
three-quarters of a mile north-northeast of Kildonan, at an elevation of
approximately 700 feet above sea-level (barometric), and they may be
reached by the trail leading to the Black Prince No. 3, which passes by
the side of one of the outcrops.
