It is interesting to note that a line drawn from the Sarita River deposit
to the Crown Prince deposit on Sechart peninsula passes almost directly
over the Mountain claim of the Copper Island group, and such a line is
parallel to the Cordilleran trend of the rock formations of Vancouver island.
The lower parts of Copper island are thickly timbered with hemlock,
spruce, and cedar, but the knoll-shaped top was burnt over several years
ago and part of it is now mantled with dense second growth of hemlock
and abundant salal brush. The exposures of magnetite occur principally
in the burnt-over part, between 650 and 800 feet in elevation; and rock
exposures are abundant. The topography of the island is favourable to the
exploration of the deposit, since a depth of nearly 800 feet below the highest
outcrop could be obtained by means of a tunnel less than 2,000 feet long.

HISTORY AND OWNERSHIP

The claims were originally staked in 1894 and Crown-granted about
1900. All the exploration and development were accomplished prior to
1902, as described in detail by Carmichael (6, page 218) in his govern-
ment report, and by H. V. Winchell in a private report in 1902. .

The claims are now registered in the name of the Sarita and Copper
Island Mining Partnership, 1221 Government street, Victoria, B.C.

GEOLOGY

On Copper island are exposed_a series of interbedded limestone,
andesite, and andesitic tuff of the Vancouver group, intruded by Beale
diorite, which is in turn cut by eranodiorite. From Clifton point north-
ward for about one mile the andesite and tuff members, cut by sill-like
masses of diorite, occur prominently with general northeasterly dips,
