magnetite lenses formed along the diorite-lime contacts. The magnetite
contains some irregularly distributed chalcopyrite, and also pyrite, pyr-
rhotite, and occasional grains of zine blende. . . . At the central
shaft about 200 tons of magnetite carrying considerable chalcopyrite
has been mined. ; ;

The Volunteer is situated about one-half mile west of the Marble Bay
mine (at Vananda) near the southeastern end of a long diorite-porphyrite
stock. . . . The croppings consist of three magnetite lenses from 30
to 50 feet in length and 10 to 15 feet in width, which have formed along the
contact of the intrusive with limestone. The central lens rests below on
limestone. It has been partly mined out and shipped as a flux. Some
chalcopyrite is present, but the percentage is small.

The Red Cloud mine, formerly the Raven, is situated about one-
quarter mile west of Spratt bay and 3 miles southeastward along the
coast from Vananda. The croppings occur in ; porphyrite
near a quartz diorite stock. . . . They consist mainly of magnetite
containing some iron and copper pyrites and are distributed irregularly
along a fissured zone from 1 to 8 feet in width, traceable along the surface

for a distance of about 150 feet. The workings . . . . include a
shaft . . . . and two drifts. . . . The lower drift extends from
the . . . . surface . . . .- fora distance of 254 feet, but does

not reach the shaft. No ore is exposed along it. The upper drift extends
from the surface to the shaft, and continues past it, following the lead for
a distance of 70 feet. Magnetite occurs along it and a considerable amount
has been stoped out and shipped asa flux. . . .

The Cape Sheaf is situated 2 miles south from Spratt bay. . . .
The . . . . porphyrites holding occasional limestone inclusions and
intruded in places by diorite porphyrites outcrop in the vicinity. The
croppings consist of a magnetite lens formed in one of the inclusions near
its contact with the porphyrite. A shaft has been sunk to a depth of 90
feet and some drifting done. . . . Dump specimens of the magnetite
show some disseminated iron and copper pyrites. The grade in copper
is not high.

The porphyrites extending from Raven creek, Spratt bay, northwes-
ward for a mile or more . . . . are intruded near the coast by
numerous quartz diorite stocks and hold numerous limestone inclusions
seldom more than a few feet across. Many of the inclusions are partly
replaced by secondary minerals and in a number magnetite lenses have
developed. Among the best known claims in the district are the Wood-
pecker and Butterfly. The Woodpecker is opened up by a shaft and some
open-cuts, all showing impure magnetite in small lenses. A shaft

has also been sunk on the Butterfly to develop a magnetite lens 60
feet in length and from 4 to 6 feet in width. The magnetite in all the
lenses contains considerable pyrite and some irregularly distributed chal-
copyrite. . . A magnetite lens situated on the coast was mined.
and used as a flux. hee

The Malaspine Mines Company controls a large group of claims cover-
ing part of Comet mountain, east of Raven creek, and extending eastward
to the coast a distance of over 3,000 feet. Comet mountain and the
surrounding district are underlaid by the massive porphyrites. ,
