the epidote amydules, from which fine veinlets radiate in all directions. The mineralization is
comparatively sparse, but is widespread and in places shows a tendency to segregation aggregates
of higher grade than the general ore tenor. In places bornite occurs in irregular veinlets of %4
to % inch width.

A zone-width of from 300 to 400 feet is indicated, with an indicated length covering the
breadth of “ Swede peninsula,” a horizontal distance of about 2,000 feet. The zone appears to
carry low-grade chalcopyrite mineralization throughout. The general copper content is about
0.6 per cent., in which are sections of concentration of from 1 to 2 per cent. copper. It is
probable that the zone extends southerly to the other side of the bay, where a similarly mineral-
ized formation is exposed. There is also a probability of parallel zones, as copper mineralization
can be picked up lateral to the described zone. The zone has been explored by surface cuts and
two tunnels about 200 and 90 feet long. With the exception of three small barren cross-dykes,
these tunnels are mineralized throughout their length in the manner described. Samples of
bornite ore from the “ Bornite” tunnel showed values in platinum and palladium.

Although the ore is admittedly low grade, the extent of the mineralized zone, the fact that
concentrations of higher grade than the general tenor do occur, coupled with the decided proba-
bility that the exposed ore occupies a horizon high above the underlying associated batholith,
indicates that the occurrence warrants more intensive exploration than it has received.
Diamond-drilling of this property is certainly warranted. The property is ideally situated on
seaboard, with an appreciable water-power contiguous to the claims.

Following is the report by Herbert Carmichael on mineral properties in this Division :—

QUEEN CHARLOTTE ISLANDS.
Report BY HERBERT CARMICHAEL,
Moresspy ISLanp.
Introduction.

In the time at my disposal on Queen Charlotte islands I haye largely confined myself to
reporting on new discoveries or claims on which some work had been done since the last report
of the Resident Engineer. There are, howeyer, a number of claims which were not visited, but
on which a small amount of work has been done; this work, I am told, has considerably
improyed the appearance of some of the properties.

Harriet harbour is on the south side of Skincuttle inlet, south-east coast of Moresby island,
and is a convenient centre from which to visit any of the mineral properties in that district.
Jedway is the Indian name for this bay and is used to designate the saltery and collection of
houses situated on the south side of the harbour.

The accompanying plane-table survey will give

a better indication of the locality than any
written description.

Geologically, the area seems a good one in which ore-deposits may be
expected. It is at or near the contact of the Coast batholith and the older rocks of w

hat Dawson
called the Vancouver series;

in fact, the contact may run the length of Harriet harbour, as
where exposed. Granodiorite rocks form the eastern shore, while hornblende andesite occurs on
the western. Interbedded with these latter voleanics, limestone is found on Harriet island at
the mouth of the harbour. On the western headland the voleanics are overlain with limestone
and both have been cut through by rhyolite dykes, striking north and south
vertically. The weathering of the limestone has left these dykes 4 or 5 feet
ing ground.

It is probable that Moresby island has been subject to voleanic
in comparatively recent geological times. There have been numerous hot springs as evidenced
by the siliceous veins and agates to be found everywhere, and one active spring is at work on
Hot Spring island, 21 miles north-west. On a former visit I found this spring had a considerable
flow of water at a temperature of 200° F., but an earthquake of some violence occurred on May
26th, when the spring entirely dried up. I have since been told that it has started to flow
