The Stoker showing is located west of the head of an unnamed, south-flowing creek (right bank tributary to Shazah Creek), between the Taku and Tulsequah rivers, approximately 81 kilometres south of Atlin, B.C.
One kilometre west of Mount Sparling on the west side of the creek valley, Lower Paleozoic volcanic and sedimentary rocks with limy sections have been intruded by hornblende and biotite monzonites possibly related to Eocene Sloko volcanism. Sloko volcanic successions unconformably overlie the Paleozoic rocks in this area. Upper Triassic Stuhini flows and tuffs are found in faulted contact with older Palezoic to Triassic (Stikine Assemblage) volcanics and sediments. Tertiary granites of the Sloko-Hyder Plutonic Suite intrude area strata.
The Stoker occurrence is underlain by marine sedimentary and volcanic rocks of the Upper Triassic Stuhini Group. Limestone interbeds have been regionally metamorphosed to greenschist facies and the limestone has been highly recrystallized. Peripheral to and locally within a six metre wide limestone bed skarn mineralization occurs. Mineralization occurs over a surface area of at least 100 metres by 60 metres before disappearing under talus in three directions. The mineralogy of the showing consists of massive to disseminated galena, sphalerite, chalcopyrite and pyrite. The north margin of the limestone bed is a 40 centimetre wide band of solid copper-zinc-lead mineralization.
Bedding in the area is oriented with a strike to 290 and a dip of 78 degrees north.
Rock samples from the Stoker showing analysed up to 35.5 grams per tonne silver, 0.48 per cent copper, greater than 1 per cent lead and 0.98 per cent zinc (Assessment Report 24616).
Work History
The Stoker and nearby Icefall (104K 130) were discovered and mapped by BC Geological Survey Branch geologists in 1993. The CST 1, 2, 3 claims were staked by Ecstall Mining Corporation in to cover the Stoker and Icefall polymetallic sulfide mineral occurrences. Exploration work on the CST claim claims by Ecstall in 1994 consisted of soil sampling (41 samples), silt sampling (5 samples), prospecting and rock sampling (23 samples). Analytical results were considered encouraging.
In 2007, Saturn Mineral's personnel conducted reconnaissance prospecting and rock sampling programs accompanied by lithological and structural observations on the Pete-ME property. In 2007, 86 rock samples were collected in the vicinity of the Icefall and Stoker showings
The showings documented in 2007 and discovered on the property before do not form any consistent zone of any considerable width, length and grade. Several gossans encountered along the surveyed valleys of the Icefall and Stoker drainages, do display signs of strong alteration, but they are accompanied by only very low-grade mineralization.
In 2008, MMI (mobile metal ion) soil sampling along with grid emplacement was carried out on the western part of the Pete-Me Property in the vicinity of the Icefall showing (104K 130). A total of 27 soil samples over 625 metres were collected. Multispectral analysis images for the entire claim area are given. These show iron oxide with lineaments, illite/sericite with lineaments; kaolinite/alunite with lineaments; and siliceous rocks with lineament. Several shaded-relief maps with lineaments are also given (Assessment Report 34484).
