The SILVER BOSS (SOUTH RIDGE) occurrence is located at an elevation of approximately 2050 metres along the southern crest of Big Timothy Mountain, 84 kilometres east of the city of Williams Lake.
Regionally, the area is underlain by gabbroic to dioritic rocks of the Buster Lake unit and granodioritic intrusive rocks of the Boss Creek and Schoolhouse Lake units of the Late Triassic to Early Jurassic Takomkane Batholith, which have intruded basaltic volcanic rocks of the Upper Triassic Nicola Group. These have in turn been intruded and are locally overlain near the summit of Big Timothy Mountain by basaltic volcanic rocks of the Pleistocene Wells Gray volcanics.
Locally at the Silver Boss (South Ridge), 1- to 3-centimetre wide quartz-filled fractures with minor chalcopyrite, magnetite and traces of molybdenite in a propylitically altered monzodiorite host.
In 2004, a sample (151674) assayed up to 0.193 per cent copper, 17.4 grams per tonne silver and 0.15 gram per tonne gold (Assessment Report 27755).
In 2006, a grab sample (185470) assayed 7.26 grams per tonne gold and 140.0 grams per tonne silver (Assessment Report 28987).
The Headwall zone is located approximately 300 metres to the northwest of the South Ridge zone in a large gully and is composed of quartz-veined float, similar to that of the main Silver Boss (MINFILE 093A 019) occurrence, along an approximately 1500 metres strike length and associated with a southwest striking fault zone.
In 2004, a sample (151797) assayed 0.723 gram per tonne gold, 0.023 per cent bismuth and 0.023 per cent tungsten (Assessment Report 27755).
From 2005 through 2014, soil and rock sampling programs carried out by Happy Creek Minerals Ltd. identified several zones of elevated copper, molybdenum, tungsten, gold and silver in soil that occur well beyond the known molybdenum deposits, including the Horse Trail zone, extending westward from the Boss Mountain mine’s molybdenum deposits and the East Breccia zone and Silverboss Shaft zone located northwest of the mine. Outcrops of quartz veins in these areas also contain elevated copper, molybdenum, gold and silver values. On both grids, the IP survey returned moderate to strong chargeability values located beneath the positive surface samples. In the Silver Boss (South Ridge) area, 1 to 2 kilometres south of the Boss Mountain mine, prospecting, geological mapping and rock sampling in 2014 found a zone of mineralized granodiorite boulders of the Takomkane Batholith. One more fractured and altered sample (SB-14-07) returned 0.52 per cent copper, 0.20 gram per tonne gold and 11 grams per tonne silver (Assessment Report 35308).
The area has been historically explored in conjunction with the nearby Silver Boss (MINFILE 093A 019) occurrence and Boss Mountain (MINFILE 093A 001) past-producing mine.
