HISTORY

The iron ore occurrences on Fenwick mountain were staked in 1901
but had been discovered a number of years earlier. A limited number
of the mining locations have been Crown-granted and are now controlled
by Mr. J. T. Laidlaw of Cranbrook, B.C., and his associates. The
development work on the claims consists of a number of small, shallow
trenches and rock cuts on the Goliath and Hematite claims.

Previously published accounts of the deposits are few in number.
The following list of titles is believed to be complete.

GENERAL GEOLOGY

The base and greater part of Fenwick mountain is composed of dark
slates and fine-grained quartzites which in the canyon of Bull river are
thrown into a series of close but open folds. On the slope of the mountain
in the vicinity of the trail leading to the iron ore mining claims, the dark
strata seem to have a general easterly dip and towards the summit of
the ridge are conformably overlain by yellowish weathering limestone
with interbeds of sandy limestone, sandstone, and shale. Both the lime-
stone series and the underlying slates and quartzites are presumed to be
of Precambrian age.

The observed ore occurrences are confined to a limited area repre-
sented by Figure 25. This area is largely bare of trees or brush. Rock
exposures are common along the ridge summit and the upper edges of the
northeastern slope and of the northern part of the southwestern slope.
Elsewhere bedrock is largely concealed by drift and talus material. The
strata are mainly thinly bedded, yellowish weathering, grey, dense lime-
stones and calcareous sandstones. Light and dark coloured shales occur
and, also, dense, hard, siliceous beds. The measures for the most part
dip regularly east-southeast at angles varying between 20 and 35 degrees,
but in places, as along the northeast slope in the general vicinity of the
local summit of the Goliath claim, the strata are much sheared and the
direction and angle of dip are variable.

Commencing on the narrow summit of the ridge, near the northwest
boundary of the Goliath claim, at the locality marked A on Figure 25 and
extending easterly to the locality marked B on the same figure, are out-
crops of dark, rather fine-grained, much altered igneous rock. At locality
B, the outcrops cease at the edge of a talus and drift-covered slope, but
