(10 d) Reco Mineral Claim, Harriet Harbour, Moresby Island
LOCATION

The mineral deposit on the Reco claim may be reached by the trail
which leads from the southwest angle of Harriet harbour along the clearing
made for a proposed tram-line to the Copper Queen. The trail follows a
nearly due south course and 1,900 feet from the beach and at an elevation
of 300 feet crosses a small stream coming from the west. The outcrops of
magnetite occur along the sides of the stream depression for a short distance
above the trail crossing.

GENERAL DESCRIPTION

For a distance of 200 feet east of the trail, magnetite, usually with very
much pyrite and some chalcopyrite, is intermittently exposed on the banks
of the gully of the stream referred to above. Most of the outcrops occur
on the north bank where the magnetite and sulphides appear as flattened
lenticular masses enclosed in shattered, fine-grained, dark volcanic rocks.
The largest body appears to be 50 feet long, to dip at an angle of about 30
degrees, and to have a maximum thickness of 10 feet. On the south bank
of the gully, magnetite with sulphides is visible at two places.

None of the exposed mineral bodies is rich enough in iron or large
enough to be of value as a source of iron ore.

(10 e) Dingo Mineral Claim, Harriet Harbour, Moresby Island
LOCATION AND HISTORY
The mineral deposit on the Dingo claim may be reached by the trail
which leads from the southwest angle of Harriet harbour, along the clearing
made for a proposed tram-line to the Copper Queen. The trail follows a
nearly due south course. At 1,100 yards from the beach and an elevation
of 500 feet, a trail leads westerly for 700 feet to the mineral occurrence at
an elevation of 800 feet. The occurrence is briefly described in the follow-
ing publications:
McConnell, R. G.: ‘‘Texada and Moresby Islands’; Geol. Surv., Canada, Sum. Rept. 1909,
p. 78.
Lindeman, E., and Bolton, L. L.: ‘Iron Ore Occurrences in Canada’; Mines Branch, Dept.

of Mines, Canada, vol. 2, 1917, pp. 18-20. Contained information is derived from the
report by R. G. McConnell.

GENERAL DESCRIPTION

The outcrops of magnetite seem to belong to one body which strikes
northwest and is bounded by crystalline limestone on the southwest and
fine-grained igneous rocks on the northeast. The boundaries appear to be
vertical. Near the southeast end the magnetite mass has a width of 15
feet, but along the strike in a distance of 40 feet decreases to a width of less
than 5 feet. Beyond this point the deposit appears to continue for a further
distance of 25 feet in the form of two diverging and tapering tonguc-like
extensions 1 to 4 feet broad. The southeast end of the body is not exposed
and it is possible that the wider part of the deposit may have a greater
length than that assumed, namely 40 feet. But granting that the total
Jength is even twice the exposed length the possible ore content is only a
few thousand tons. The exposed ore is of comparatively uniform quality,
low in sulphide and with a relatively small amount of garnet and other |
gangue materials. The contact with limestone is sharp, but with the igneous
rocks it is less clearly defined with, in places at least, a border zone several
feet wide largely formed of garnet, etc.
