covered by the claims. In the vicinity of the boundary the granitic
rocks hold large and small fragments of the older rocks and form broad,
dyke-like areas within them.

The magnetite occurrences are confined to the area of sediments and
voleanics. These rocks for the most part consist of dark, fine-grained
mica, and hornblende schists. Several narrow bands of crystalline lime-
stone occur near the southwest margin with a definite northwest strike.
Some rock varieties resemble metamorphosed clastic rocks, but presumably
the major part is of volcanic types, either intrusive or extrusive or both.
Fine-grained dykes are numerous and some are younger than the mineral
depesits. The sedimentary and volcanic strata presumably are nearly
vertical and in places are contorted.

DESCRIPTION OF MAGNETITE OCCURRENCES

The magnetite occurs in comparatively small amounts at a number
of localities which lie towards the middle of the band of schistose rocks and
were observed at intervals over a length of 2,500 feet within the limits of
the claims and at one place to the northwest of the claims. Within the
area of the claims, the mineralized localities lie in a zone with a maximum
width of 1,500 feet. Within this zone it is believed that all rock outcrops
were examined and that any mineralization of significant amounts was
noted. As much of the zone is drift-covered it is possible that important
magnetite deposits are present beneath the drift cover. The various
magnetite-bearing outcrops are described below in the order of their
occurrence from southeast to northwest. The positions of the occurrences
are indicated on the accompanying Figure 9.

Occurrence No. 1. An exposure showing magnetite and magnetite-
impregnated rock with a total width of 1 to 2 feet and a length of several
feet. Seventy feet to the southeast, lower down on the hill-side, a stripping
30 feet by 10 feet holds irregular, discontinuous patches of magnetite, the
largest having an area of less than 2 square feet. To the northeast and
north, within a radius of 75 feet, the schistose rocks here and there show a
few small patches (up to 2 feet in length) of magnetite.

Occurrence No. 2. (250 feet north of No. 1.) An isolated outcrop
of magnetite 2 feet in diameter.

Occurrence No. 3. (1,050 feet southwest of No. 2.) A streak of magne-
tite 2 feet by 6 inches in green schist.

Occurrence No. 4. (900 feet north of No. 3, 650 feet west of No. 2.)
An outcrop of magnetite triangular in shape, with sides measuring 10 to 15
feet. About 75 per cent of the outcrop is magnetite, the rest being country
rock. Parts are very rusty, due to pyrite.

Occurrence No. 5. (750 feet north of No. 4.) A very little magnetite
and pyrite in a short zone not over 1 foot broad.

Occurrence No. 6. (100 feet north of No. 5.) Over a length of about
50 feet along a low cliff face, magnetite appears at intervals in a rusty-
weathering schist. The largest single mass of magnetite outcrops over
an area of 10 feet by 4 feet in which magnetite and rock are present in
about equal amounts.

Occurrence No. 7. (175 feet north of No. 6.) An area 25 feet long
by 8 feet broad bears much magnetite in irregular patches in schist.
