These veins consist of galena, sphalerite, pyrite, and tetrahedrite in a gangue of quartz. They are very well mineralized on the surface and in some places are practically solid sulphide. Surface exposures on the upper vein assay up to 250 ounces in silver a ton. Underground the vein is narrower and much lower in grade. The lower vein assays 150 ounces or less in silver a ton. The upper vein is developed by open-cuts and a drift adit 100 feet long. The lower vein is well exposed in open-cuts. A crosscut adit 45 feet long has been driven to intersect the lower vein but has not been driven far enough to reach its objective. These mineral showings are quite attractive and should be developed further.

Three veins have been explored on the Bayview group which adjoins the Gold Cliff group on the west. The workings are about 4,000 feet above sea-level. The veins are parallel to each other and to the contact of the Coast Range batholith which here strikes west. One vein is at the edge of the batholith and the other two in rock adjacent to the batho- lith within 700 feet of the contact. The veins are individually 2 feet or less in width and consist of pyrite, galena, sphalerite, and tetrahedrite, in a gangue of quartz. The development consists chiefly of open-cuts from some of which ore has been shipped. A total of 9 tons of ore shipped in 1925 assayed 170 ounces of silver per ton, 16 per cent lead, 21 per cent zine, and a little more than a dollar in gold per ton.

The veins on the two groups contain shoots of ore that can be mined and shipped without much concentration. They are easy of access and close to Stewart. They warrant more thorough exploration.
