GENERAL DESCRIPTION

In the immediate vicinity of the ore deposit on the Magnet claim the
rocks are mainly fine-grained intrusives or extrusives, but one outcrop of
dark crystalline limestone was noted. Several hundred yards to the east
is the western edge of a large body of granitic rocks.

The ore-body consists mainly of magnetite, but with in places con-
siderable garnetite and included masses of country rock. It outcrops on
a slope falling to the north and is exposed over a curving, band-like area
350 feet long and with a maximum width of 75 feet. The mass strikes
southerly and disappears beneath drift at both ends. At the southern end
outcrops of country rock indicate rather closely the limits of the ore-body
in that direction, but at the north end there is a wide, drift-filled depression
and nothing to indicate how far the ore-body may extend northward
beyond the last outcrops. At the north end the magnetite outcrops on a
steep bluff rising 55 fect in an horizontal distance of 30 feet. At the base
of this bluff a tunnel has been driven 22 feet southward along the strike of
the ore-body. In the tunnel, magnetite is exposed for a length of about 5
feet from the portal, with much sulphide at the boundary between magne-
tite and the country rock which appears along the rest of the tunnel length,
is much shattered, and is traversed by calcite veins. At the tunnel mouth,
magnetite outcrops eastward for 20 feet to the boundary of the body and
for 12 feet to the west to where outcrops are concealed.

Along the strike of the body, 150 feet from the tunnel entrance, a
trench exposes the mass across nearly its full width. Towards the western
edge, over a width of more than 30 feet, as exposed in the trench, the ore-
body is very largely of garnetite, but on the eastern side, magnetite pre-
dominates. On the whole the ore-body at the northern exposures is
nearly solid magnetite, but towards the south end the magnetite content
decreases and in places the material is not an iron ore. Disseminated
sulphide is present everywhere and is abundant in places along or near the
eastern margin of the magnetite mass where there are also masses of barren
country rock.

The magnetite body has a faintly developed, sheeted appearance
and a well-defined parting, both dipping at a low angle to the west. Along
the western side of the body the boundary is rarely visible, but in various
places country rock is exposed close to the edge and at each place rises
higher than the neighbouring outcrops of magnetite. Along the east side
of the mass of ore, the country rock wherever exposed lies lower than the
adjacent magnetite and in several places may be seen for a few inches
to pass beneath it, as also seems to be the case where the tunnel has been
driven. Apparently the ore-body is tabular, and dips at a low angle to
the westward.
