wide striking north 10 degrees west, dipping 30 degrees west, and lying in
sheared quartzite with approximately the same strike and dip. The vein is
locally split into several veins. The quartz is mineralized with some pyrite
and galena.

CANYON AND TYEE GROUPS

The Canyon and Tyee groups of claims are held by A. Drinkwater
and associates. The Canyon group is on Sugar creek below Little Mustang
creek, and the Tyee group is about 2 miles west. Access is via the Sugar
Creek trail, and the distance is about 12 miles northwest of the Barker-
ville road at the foot of Jack of Clubs lake. A short branch trail from
Little Mustang creek leads to the Tyee group.

On the Canyon group many quartz veins are exposed on the banks of
Sugar creek, either naturally or in open-cuts. They occur in rocks striking
west-northwest and dipping about 40 degrees north. No vein has been
traced for over 100 feet, and all are very sparsely mineralized with pyrite.
Most of the veins are parallel to the strike of the enclosing rocks, but some
strike north-northeast. Low values in gold are reported.

The showing on the Tyee group is a body of quartz 20 feet by 50 feet,
containing some pyrite, galena, sericite, and inclusions of argillaceous schist.
A small outcrop of argillaceous schist near the vein strikes west-northwest
and dips 40 degrees north. The quartz body appears to strike northeast
and dip 60 degrees northwest, but a cover of drift obscures relationships
and it is not even certain that the quartz is in place. Low values in gold
are reported. .

CARIBOO CORONADO MINING SYNDICATE

In 1934 the Cariboo Coronado Mining Syndicate carried on surface
and underground exploration on its holdings northeast of Willow river
opposite Island mountain.

The country rock consists of limestone and schist of the Barkerville
formation and of argillite and quartz-sericite schist of the overlying Pleasant
Valley formation.

An adit was driven north 13 degrees west for 1,150 feet (August, 1934)
into the mountain southeast of Martin creek to cut veins exposed on the
surface 500 to 800 feet higher. The objectives were not reached, but the
adit cut several quartz veins a few inches to 2 feet wide and several bands
of calcareous argillite and of green schist partly replaced by pyrite.

Another adit was driven north 14 degrees west for 385 feet into the
mountain northwest of Martin creek. This adit cut several narrow quartz
veins and many quartz gashes and stringers of irregular shape. Some of the
quartz is well mineralized with pyrite. A band of replacement ore 2 inches
wide cut by the adit assayed $6 a ton in gold. Open-cuts and a shaft on
the mountain top expose several quartz veins a few inches to 8 feet wide
mineralized with galena and pyrite. The veins strike north 30 degrees
east to east. Picked samples have assayed more than half an ounce of
gold a ton. The veins are mostly in argillaceous and sericitic schists, but
one is in a body of undefined shape of quartz porphyry.
