three roughly parallel “veins”. These “ veins” lie 30 to 40 feet southeast
of the fissure followed for 400 feet and may connect with the sheared zone
that crosses the adit 100 feet from the portal. The three “veins” are 150
feet vertically below the rich sector of the main zone exposed in the
southwest end of the upper adit. Presumably, they unite somewhere
between the two levels to form the wider zone. Where visible for 60 feet
along the drift and in short crosscuts, the three “ veins” range from 1 to
10 inches in width and are well mineralized with arsenopyrite. Company
assay plans show for a length of 35 feet from the face of the drift, 0-03 to
0-07 ounce of gold a ton across widths of 5 feet. These samples include
several feet of barren rock.

The extent of the zone northeast of the 300-foot stripped section is
not well known. Two open-cuts along the strike, 140 and 335 feet,
respectively, northeast of the stripped section, are now slumped in and
only small amounts of rusty, altered rock are visible on the dump. In a
third cut, 70 feet farther along, there is a 3-foot wide sheared and silicified
zone that carries 3 to 5 per cent of arsenopyrite associated with quartz.
This sheared zone strikes north rather than northeast and dips steeply.
Bedrock is visible in three trenches that lie between elevations of 4,650
and 4,700 feet, but in none of them is there evidence of the presence of the
zone. In the bed of Henderson Creek 1,000 feet northeast of the stripped
section there is a sheared zone, 4 feet wide, exposed for about 50 feet.
The sheared rock is altered and bleached and contains narrow, sparsely
mineralized lenses of quartz. In the northeast bank of the creek, one of
these attains a width of 12 inches and carries up to 20 per cent of arseno-
pyrite and sphalerite with a little chalcopyrite. A 12-inch channel sample
taken across it assayed: gold, 0-285 ounce a ton; silver, 1-01 ounces a ton;
zinc, 5-74 per cent.

Other small exposures of vein materials occur farther northeast along
the same general strike.

The Coronado property is on the southwest slope of Hudson Bay
Mountain about 16 miles west by road from Smithers. The workings are
half a mile northwest of the Duthie mine and lie between elevations of
3,400 and 3,650 feet. A good road crosses the claims a short distance
below the mineralized zones.

This group is one of the earliest mineral locations staked on Hudson
Bay Mountain. In 1905, the owners, J. R. McDonald, Simpson, and
Fleming, sent out 4 or 5 tons of hand-sorted galena ore by pack-horses to
Hazelton and thence to the smelter via boat on Skeena River. Between
1912 and 1914, extensive development work was undertaken, the zones
being explored by four adits and by open-cuts and stripping. A shipment
of 60 tons of silver-lead ore was made early in 1915. In 1919 the Skeena
Mining and Milling Company was organized to develop the Victory and
