with chalcopyrite. In general the vein is very low grade, but assays across
18 feet of a well-mineralized part have yielded more than 2 per cent copper.
On the Eagle and May Queen claims lying north of the Princess May
claim a large quartz vein, in part banded with country rock, strikes north-
east. The vein is up to 35 feet wide and has been traced for 3,000 feet
between the elevations of 2,200 and 3,500 feet. It is locally well mineralized
with chalcopyrite and pyrite and the outcrop stands out as a rusty band.
The vein was diamond drilled by the Granby Consolidated Mining, Smelt-
ing, and Power Company and it has been stated that the drilling indicates
the presence of 522,000 tons of probable ore assaying 1-71 per cent copper
and 590,000 additional tons of possible ore assaying 1-4 per cent copper.
Local pockets, several feet across, were encountered in the drill holes, con-
taining up to 10 per cent copper. Values in gold and silver are very low.
The Granby Consolidated Mining, Smelting, and Power Company
drove a 700-foot adit on the Star claim which lies half a mile northwest of
the Eagle claim. The deposit on the Star is a quartz vein several feet wide
and locally well mineralized with chalcopyrite and pyrrhotite. The vein
strikes north and has been traced for 700 feet. The adit, driven at an eleva-
tion of 375 feet above sea-level, disclosed an ore shoot from which the com-
pany shipped 4,000 tons of copper ore.
The vein matter on the Maple Bay groups is of a type not found else-
where in Portland Canal area. The white quartz veins contain bunches and
gashes of clean chalcopyrite and pyrrhotite. In many places the sulphides
appear to occur as a filling occupying all available space left after the
quartz has solidified. The veins are unusual in that in them pyrite, galena,
and sphalerite are extremely rare. The origin or source of the vein matter
is believed to be intrusive rocks represented on the surface by amphibolite.

Monday Group (Locality 112)

The Monday group is 6 miles up Bulldog creek. Considerable surface
work has been done on mineral deposits containing pyrite, galena, and
sphalerite.

The holdings of the North Country Mining Company, Limited, are
on the east side of Georgia river at its head. The trail to the property is
up Bulldog creek. The principal holdings of the company consist of the
Gloria group of claims.

The country rock is diorite with sedimentary and tuff inclusions near
its contact with a large body of the Coast Range batholith to the north-
west. The whole complex has been sheared locally and intruded by
numerous diorite dykes.

Several adits aggregating more than 1,200 feet in length have been
driven under narrow quartz veins in shear zones. The veins are very
sparsely mineralized and have not been followed on the surface for any
creat distance.
