DESCRIPTION OF DEPOSITIDESCRIPTION DUGISEMENT The formation consists chiefly of folded, silicified argillite, with possibly some intercalated tuff beds, striking northwesterly and dipping northeasterly at varying low angles. These rocks are intruded by bosses, spurs, and dykes of granitic rocks related to the adjacent Coast Range batholith. The mineral deposit consists of a quartz vein striking north- westerly, dipping about: 15'E with the mountain slope and conformable with the formation. The vein has been traced 230 feet northwesterly from the main exposure. About 1,000 feet to the southeast a 24 inch wide quartz vein outcrops in a creek. The main exposure shows a width of from 1 inch to about 4 feet, mineralized with patches and streaks of galena, sphalerite, tetrahedrite, and chalcopyrite. In an open cut a width of from 3 to 4 feet of quartz is exposed, with irregular mineralization but carrying a streak of possibly high-grade mineralization 2 to 3 inches wide on both the hanging and the foot-wall sides of the vein.
