The Fork showing is located northwest of the main Silbak Premier mine, 22 km north of Stewart, B.C. The showing was noted historically as part of a silicified zone along the "West" or "Northwest" mineralized zone which contains discrete pods of mineralization. For a more extensive capsule geology and bibliography refer to the Silbak Premier Mine (104B 054).

The area is located in the Intermontane Belt bounded on the west by the Coast Crystalline complex and on the east by the Bowser Basin, in the volcanic arc assemblage of the Stikinia Terrane.

The showing is hosted by the Upper Triassic to Lower Jurassic Hazelton Group, Unuk River Formation. The Hazelton Group is a north- west trending belt of folded dacite flows, andesite flows, breccia and lapilli tuff containing a thick sequence of argillites and silt- stones infolded along a synclinal axis.

The andesite, at least 750 metres thick, is intruded by Early Jurassic Texas Creek plutonic suite dacitic porphyry dykes and is unconformably overlain by volcaniclastic and epiclastic rocks. Potassium feldspar porphyry (historically known as the "Premier Porphyry") is spatially associated with mineralization; this relationship is believed to indicate a Lower Jurassic mineralization age. The ore in the area is predominantly discordant but locally concordant with the moderately northwest-dipping andesite flows, breccias and dacite flows.

Hydrothermal alteration zones related to the mineralizing system are represented by a proximal silicification/quartz stockwork and potassium feldspar and/or sericite facies potassic alteration. Peripheral to mineralization is a propylitic alteration assemblage of carbonate, chlorite and pyrite.

The Fork showing is about 15 metres wide and extends for 400 metres between the Hope-Power zone (104B 154) and the Woodbine workings (104B 090) along the steep to vertical "Northwest" or "West" zone. The mineralization is not significantly offset by the Cascade or Lesley Creek faults. Mineralization, similar to the Hope-Power showing and the Woodbine workings, is within silicified and brecciated rock along the same porphyry-andesite contact as the Hope-Power showing. The porphyry is 50 to 75 metres wide and a limonitic, silicified and pyritized alteration zone is proximal to the contact.

Mineralization consists of massive sphalerite pods, disseminated pyrite and disseminated chalcopyrite. Gangue minerals are quartz, potassium feldspar, chlorite, carbonate and others.

From 2009 to 2020, Ascot Resources Ltd. conducted drilling and geophysical surveys in the Premier Gold project area. See Premier (104B 054) for details and work history.
