Omineca Gold Quartz Mines, Limited, is at present developing a gold-
quartz property known as the Dardanelle group, situated 12 miles up
Zymoetz river. Nicholson Creek Mining Corporation is doing some work
on Hardscrabble creek on the Phoenix group, where some molybdenum
occurs in quartz veins associated with pyrite.

Very little prospecting was done in the area during the 1936 season
as all available local men were employed throughout the summer in recon-
struction work following the flood in May.

Late in the season T. Turner located a wide shear zone containing low
gold values on the Excelsior claim and W. Hagen found a vein containing
silver, lead, and zine on the Black Bull claim. Both properties are on
Kleanza mountain not far from the Zymoetz River bridge. E. M. Angell
spent some time prospecting the Silver Mitts group on the north fork of
Chimdemash creek. D. Wilson reported new vein discoveries on Little
Beaver river west of Kitsumgallum lake. The face of the main adit drift
on the Globe claim was advanced several feet.

TYPES OF MINERAL DEPOSITS

Mineral deposits containing gold, silver, copper, lead, and zine are
numerous in the area, and molybdenum and tungsten are also found. Most
of the deposits are small, but there are a considerable number of ore occur-
rences of economic importance. The deposits occur in the volcanic and
sedimentary rocks of the Hazelton group, and in the intrusive tongues and
stocks of the Coast Range batholith that cut these rocks. The minerals
are usually contained in quartz veins that occur along faults of small dis-
placement or along sheared zones. Some of the quartz veins occur along
the walls of quartz-albite (alaskite) dykes. One vein occurs along one
wall of an andesine diorite porphyry dyke, and in another place veins occupy
cross fractures in a highly altered albite diorite dyke. There are in addi-
tion a few vein occurrences of massive sulphides.

The ore deposits may be divided into the following types:

(1) Gold-quartz veins containing chiefly pyrite. Veins of this type occur on the

Victor, Grotto, and Golden Crown properties. 3

(2) Gold-quartz veins containing pyrite, chalcopyrite, galena, and sphalerite. The
Fiddler, Patmore, Bermaline, and Zona May veins are good examples.

(8) Gold-quartz veins containing pyrrhotite, arsenopyrite, and pyrite, with small
pmounts of galena and sphalerite. Small veins of this type occur on Whiskey
creek.

(4) Quartz veins containing galena, sphalerite, and chalcopyrite, with a low silver
content. The veins on the Windfall, M. and M., and Galena properties are
examples.

(5) Quartz veins containing bornite and chalcocite. with an appreciable silver con-
tent. The Silver Basin, Silver Crown, and Singlehurst veins are of this type.

(6) Quartz veins containing chalcopyrite. The United St. Croix, Shenandoah, and
Continental veins are examples.

(7) Sulphide veins and replacements of bornite and chaleocite, some with
chalcopyrite and galena and some with an appreciable silver content. Ex-

amples of these are found on the Silver Mitts, M. and K., Lucky Jim, and
Diorite properties.

No evidence was found to alter the accepted view that the ore deposits
have been derived from a common source, the Coast Range batholith. The
