The Friday showing is located about 980 metres north of Maple Bay on the east shore of Portland Canal, about 55 kilometres south of Stewart and 12.5 kilometres due west of Anyox.
The region is underlain by a roof pendant, consisting of volcanic and sedimentary rocks, within the Eocene Coast Plutonic Complex. These pendant rocks have been correlated with Middle-Upper Jurassic Hazelton Group rocks and overlying upper Middle to Upper Jurassic Bowser Lake Group sedimentary rocks (Geological Survey of Canada Open File 3453). The Hazelton rocks consist of variably chloritized pillow and massive andesite and basalt with minor mafic tuffs. The overlying Bowser Lake sediments consist of argillite, siltstone and sandstone with minor chert and limestone. There are two observable phases of folding in the area, an initial north-northeast trending phase followed by a later east-northeast trending phase.
At the Friday showing, a coarse grained milky white quartz vein is hosted in interbedded dark grey siltstone and fine-grained sandstone. Siltstone inclusions occur along the western margin of the vein. The Friday vein, 4 to 5 metres in width, strikes 170 degrees for up to 180 metres and dips near vertical and is exposed over a strike length of 50 metres. Minor reddish brown staining occurs along fractures and some rusty weathering zones are locally present. Well foliated prismatic crystals occasionally line voids. Only very minor amounts of sulphide mineralization are present. It represents the best potential as a silica source in the Maple Bay area. The quartz appears to be relatively pure and the occurrence is only 500 metres from the shore (Open File 1987).
