The deposit is too small, and the grade of magnetite too low to be of
any value as an immediate source of iron ore.

(49 b) Defiance Deposit, Alberni Canal
(See Figure 39)
LOCATION

The deposit occurs near the headwaters of Handy creek, which enters
Alberni canal on its west side about 2 miles from the entrance to Uchucklesit
harbour. It may be reached in a distance of 14 miles by a good foot trail
that leaves Alberni canal from a small bay about half a mile southwest
of the Monitor mine landing.

The outcrops are located on relatively flat ground, constituting a
rocky bench on the valley slope, at the foot of steep limestone bluffs.
The elevation is about 1,000 feet (barometric) above sea-level; and the
ground is drift-covered, heavily timbered with balsam and hemlock, and
thickly overgrown with salal brush.

HISTORY AND OWNERSHIP

The Defiance and Defiance No. 1 mineral claim were located in April,
1902, by Messrs. Monie and Commoford of Alberni (6, pages 213-214).
Brewer (21, page 21) states in 1916 that these two claims are Crown-granted
and belong to Michael Commoford of Alberni.

GEOLOGY

Hornblende diorite (Beale) occurs here in intrusive relations with
respect to a large body. of fine-grained, greyish limestone (Nitinat) con-
taining nests and stringers of calcite and siderite. Both rocks are altered
in the vicinity of the contact zone; the diorite to a fine-grained, chert-like
porphyritic phase, and the limestone to masses of garnet, epidote, and
quartz. In the two tunnels and in the cliffs to the northwest of the cabin,
the limestone can be plainly observed to be nearly flat-lying, with local
dips up to 10 degrees or 15 degrees, and to lap over the intrusive. Roof
pendants of altered limestone (garnet, etc.) occur within the diorite strung
out in a northeast-southwest direction. Manifestly, the diorite exposed
in this area is the top of the intrusive body that is just barely unroofed
by the erosion of overlying limestone. In this respect the geology of this
deposit is somewhat similar to that of the Sarita River magnetite, and
also to that of the Glengarry-Stormont area, Nootka sound, to be discussed
later.
