These claims are reached by the same route as that described for the
Conqueror, and the old trail to the Conqueror traverses the Bugaboo
Creek group from end to end. The main workings are located well above
and to the south of the trail, and may be reached along two almost obliter-
ated zigzag trails up the mountain side. The group is, as an average
about 2 miles closer to Port San Juan than the Conqueror group. oa

The main showings of the group, on the Sirdar, Little Bobs, Baden-
Powell, General French, and General White claims, are located at elevations
varying from 1,300 to 1,700 feet above sea-level, and lie on the steep
northeasterly sloping mountain side leading down to Bugaboo creek.
The country is very similar to that in the vicinity of the Conqueror group,
and is overlain in many places with a thick mantle of glacial drift. Timber,
standing and fallen, and underbrush, are abundant, making the examination
of the claims and their exploration difficult.

HISTORY AND OWNERSHIP

These claims were located in 1900 by Kirkpatrick brothers and J.
Williams! and were later sold to the Gordon River Iron Ore Company.
They are now controlled by the Godman estate, whose agents are Edwards
and Ames, Pacific building, Vancouver, B.C.

The principal stripping, open-cutting, and the driving of the tunnel
were done between 1900 and 1907.

GEOLOGY

The Sirdar deposit of magnetite is located near the south line of the
Sirdar claim, and about 300 feet from the southwest corner. In a straight
line, running west-northwest, it is distant 2,800 feet from the falls on the
Conqueror claim; and lies between elevations of 1,600 and 1,660 feet above
sea-level. It lies on a thinly wooded slope facing northeasterly and leading
down to Bugaboo creek. The mass of magnetite constitutes a bold bluff-
like hammock on the otherwise uniform slope, and is covered over with
a thin veneer of moss and some drift. A few, small, scrubby evergreens
are also found and these have probably grown during the period of twenty
years since the development ceased. ;

There are four types of rocks exposed in the immediate vicinity,
namely, quartz, diorite, dykes of hornblende porphyrite and lamprophyre,
and residual fragments of unreplaced crystalline limestone within the
magnetite. Quartz diorite porphyrite of intermediate grain, consisting
of phenocrysts of andesine in a quartz-feldspar mosaic, with minor amounts
of orthoclase, hornblende, biotite, and magnetite, constitutes the country
rock of the deposit. It may be observed in intermittent exposures along
all contacts of the magnetite, and outcrops in prominent cliffs 80 feet
to the south of the deposit, and close to its eastern edge. It also occurs
at the portal of the tunnel, and in two belts within the tunnel, from the 62
to the 72-foot points, and from the 84-foot point to the face, a distance
of 19 feet. Dykes of hornblende porphyrite and lamprophyre occur near
