Molybdenite occurs on the Eureka claim, about 2 miles south of the
Forest Lookout station, at an altitude of 4,800 feet on Thornhill mountain.
The owner, J. A. Michaud, has cut a rock trench 6 feet wide, 6 feet deep,
and 25 feet long on the best showing and has removed some high-grade
ore. The actual outcrop over which molybdenite may be seen to occur is
less than 50 feet in diameter, but the granite is spotted with small, rusty
patches over an oval area of about 100 feet by 200 feet. The mclybdenite
occurs in rosette-shaped forms from 1 to 2 inches in diameter, the crystal
groups commonly being in clusters. The molybdenite is associated with
small, irregular, pegmatite dykes which are intrusive into a fine-grained,
grey granite. In the trench the ore occurs in irregular-shaped pockets
connected by very small, pegmatitic stringers. The pockets are outlined
with a rust-coloured stain resulting from the oxidation of the pyrite that
accompanies the molybdenite, and they contain abundant sericite and
pseudomorphs of chlorite after hornblende. In places the molybdenite
rosettes are coated by the straw-yellow oxidation product, molybdite.

Fifteen feet east of the rock trench, a 2-foot pegmatite lens striking
north 60 degrees east and dipping 30 degrees to the southeast may be traced
for 40 feet. Its surface exposures show very little molybdenite.

The Omineca Gold Quartz Mines Company is developing the Darda-
nelle group of mineral claims situated on the north bank of Zymoetz
(Copper) river, about 14 miles from Copper City and 18 miles from
Terrace. The company’s mine office is at Terrace, the head office is at
Vanderhoof, B.C.

During the summer of 1935 a wagon road 10 miles fone was built
along the north side of Zymoetz river, connecting the mining property with
the Terrace-Usk highway at the Zymoetz River bridge and preliminary
mining equipment and supplies were transported to the property in pre-
paration for mining operations.

Quartz diorite and granodiorite predominate on the mining claims.
They are evidently differentiates of the same magma as they may be seen
to grade imperceptibly one into the other. These rocks on the Independence
and Dardanelle claims are intruded by a dyke-like body of medium-
grained, pink granite. A quartz albite dyke runs in an easterly direction
across the Trail, Trail fraction, Independence, Dardanelle, and No. 19
mining claims. On both the east and west it passes beneath a cover of
