In a draw 200 yards to the west of south from the Maple Leaf shaft,
is a small trench showing several feet of hematite ore followed to the west
by quartzite impregnated with much vein quartz. The few feet of ore

carries much vein quartz in disseminated grains, holds small magnetite
crystals and considerable pyrite. A short distance south of this occur-
rence, on the side of a second draw, are a number of outcrops which, com-
mencing at the south boundary of the Maple Leaf claim, occur intermit-
tently over a distance of 200 yards along a general northeasterly course.
The more southerly of these exposures consist largely, almost solidly, of
vein quartz in places showing to a width of 10 feet. In some places there
is little or no hematite, in other places ore with a width of several feet is
exposed. Farther northeast, the amount of vein quartz decreases and
the exposures consist of altered rock, in part igneous, veined with quartz
and impregnated with hematite.

Near the south boundary of the Keepsake claim, close to the trail,
and 750 yards south of the Maple Leaf shaft, a small open-cut in drift
shows at its rock face a body of hematite, 8 feet wide on the north side of
the cutting and less than 4 feet wide on the south side only 10 feet away.
A diamond-drill hole was driven here in 1901. It is reported to have
followed the ore along the dip for a considerable depth. The ore consists
of hematite with, here and there, small irregular bodies of quartz. Langley!
states that a sample taken by him across the 8 feet of ore when assayed
gave the following returns:

The ore is largely very dark grey, nearly black, hematite, partly
very dense, partly in minute scales giving a brilliant lustre to a series of
partings cutting one another at obtuse angles. The material exhibits
occasional narrow quartz veinlets. There are all gradations from pure or
nearly pure hematite to paler coloured material composed largely of
minute grains of quartz in a hematite matrix. A characteristic feature,
especially noticeable in the more siliceous parts, is the presence of
innumerable cavities usually so small as to escape detection unless specially
sought for. In places the cavities are so numerous as to give the ore a
scoriaceous appearance.

East of the ore-body, the mineralized rock has been stripped for 42
feet across the strata. The first 15 feet have the appearance of a breccia
composed of angular fragments of pinkish quartzite varying in size from
such as are several inches in diameter down to minute specks. These
fragments in amount greatly exceed the matrix which in part is of fine-
grained hematite, in part is largely of minute quartz grains. All gradations
occur from large, homogeneous quartzite fragments to areas of hematite
impregnated with minute quartz grains. Many of the larger fragments
are penetrated and crossed by seams of hematite. In places hematite i is in
excess of the quartzite and in such spots parts of the matrix may be nearly
pure hematite, but such parts grade into more siliceous material holding
specks and larger fragments of pink quartzite. In this breccia-like material,
the remains of quartz veins are visible and this material seems to bear the
same relations to the hematite as does the quartzite.
