No. 4 ore-body was discovered by diamond drilling. The body was
100 feet thick and extended 500 feet down the dip. Its maximum length
along the levels was 600 feet. It lay along the contact with a broad
bulge at the top and tapered to a thin wedge at the bottom where it ended
in silicified amphibolite. The dip at the top is 10 to 60 degrees east under
the argillite roof. The wall-rocks are strongly silicified and alteration of
rock is as intense where the ore-body is narrow as where it is wide, as at
the top. The ore-body consisted of sulphide like No. 1 ore-body. Pyrite
and pyrrhotite were about equally abundant and were much more plentiful
than chalcopyrite. Shoots of pure pyrrhotite occurred on the upper side of
the body at the greenstone-argillite contact.

No. 5 ore-body was discovered by diamond drilling. It was 180 feet
wide and extended 700 feet down the dip. Its maximum length along the
mine levels was 500 feet. It lay along the contact between amphibolite
and argillite and the main part was situated where the dip of the argillites
changes. The upper part of the body dips east, the lower part dips west,
and the intervening greater part is vertical. At its north end the ore-
body splits in two, the eastern part extending, parallel to the bedding, into
slightly silicified argillite. Below, the body enters amphibolite and by a
decrease in the chalcopyrite content grades into a large pyritic body. The
ore is much like that of No. 4 and No. 1 bodies, being heavy sulphide in
which pyrrhotite is common in the upper part but in which pyrite and
pyrrhotite are both plentiful. The amphibolite and argillite of the wall-
rock are intensely silicified.

No. 6 ore-body lies along the contact and in the southern part of the
favourable structure. It has a maximum width of 70 feet, a depth down
the dip of 300 feet, and a length along the levels of 500 feet. The body
strikes northeast and is vertical, but at a depth of 150 feet turns somewhat
and enters sheared amphibolite to the northwest. It ends downward at a
fault dipping 45 degrees west. Silicification of the wall-rocks is strong
where the body lies along the contact but is not present around the ore
where it lies in amphibolite, the wall-rock alteration in those parts having
resulted in the formation of chlorite. The ore is of the usual heavy sulphide
contact type except in that part of the body lying in amphibolite where it
consists of a greenstone ribboned with bands and lenses of sulphide.

No. 7 ore-body is of the contact type and lies north of No. 4 body. It
has a yet been mined, but appears to be much smaller than the others
nearby.

No. 8 ore-body is of the contact type and lies just east of No. 6. It
appears to be entirely composed of uncommercial ore.

The Homestake group of three mineral claims is west of Anyox and
adjoins the holdings of the Granby Consolidated Mining, Smelting, and
Power Company. The country rock is argillite. Boulders of copper ore
have been found on the property, but are reported to have a greenstone
gangue and, therefore, did not come from the area covered by the Home-
stake group.
