DEVELOPMENT

The deposit is developed by two tunnels, 50 feet apart vertically,
the one almost directly below the other, and a number of shallow open-cuts
and strippings. The tunnels are driven at right angles to the longest
dimension of the exposed ore, the upper one for a length of 108 feet, and
the lower one for 114 feet. The portal of the latter is badly caved, making
entry impossible. The old strippings are grown over with moss and
underbrush, and many of the open-cuts are in a caved condition.

ECONOMIC CONSIDERATIONS

Extent of Deposit

The greatest longitudinal extent of the deposit is 320 feet and the
greatest exposed width is 90 feet. The greatest proved depth is 150 feet
from the highest outcrop to the level of No. 1 tunnel. The corresponding
figures for the centrally outlined body of better: quality magnetite are
200 feet, 70 feet, and 50 feet, respectively.

There are three possibilities for further extent of the deposit. (a)
There is a possibility of an extension to the northwest beyond mapped
boundaries, but there is no evidence suggesting or disproving this, except
the absence of exposures. (b) There seems to be very little possibility
for an extension to the southeast, as the three mapped exposures of quartz
diorite appear to materially block the way. However, the ore zone might
swing more directly towards the east and pass to the north of these expo-
sures. In this connexion a statement may be quoted from a private report
by Edwin Thomas (undated but probably previous to 1910) that “four
hundred feet to the east of the natural outcrop the ore has been stripped
and undergrowth and timber removed, exposing the vein for a distance
of 75 feet in length and 40 to 50 feet in height.”” No indications of this
exposure could be found by the writer. (¢) Downward extension below
the lower tunnel is probable for a few feet at least (to a depth equal to
half the length of exposure), and possible to a much greater depth.

Analyses

Only two analyses of samples from this deposit are available, and
they are quoted herewith. They manifestly represent the higher grade
part of the deposit.
