Capsule Geology

The Silver Boss (Dogtooth) occurrence is located at an elevation of approximately 2060 metres in the upper reaches of 10 Mile Creek on the northeastern slopes of Big Timothy Mountain.

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, a 1- to 5-metre wide, northeast-trending shear zone cuts granodiorite and monzodiorite. The shear zone is variably silicified with moderate to strong chlorite-epidote and sericite±quartz-potassium feldspar and contains 5- to 17-centimetre wide, sub-parallel quartz veins with minor pyrite and chalcopyrite. The shear zone has been traced along strike for at least 150 metres.

In 2005, a sample (151703) of quartz vein material assayed 53.01 grams per tonne gold and 343.0 grams per tonne silver over 10 centimetres, whereas a 1.0 metre chip sample (185634), taken approximately 100 metres to the northeast, yielded 10.06 grams per tonne gold and 26.0 grams per tonne silver (Assessment Report 28344).

In 2006, a grab sample of quartz vein material assayed 53.18 grams per tonne gold and 365.0 grams per tonne silver (Assessment Report 28987).

Two other zones (South East Float and 10 Mile Creek) of mineralization are reported in the area.

The South East Float zone is located at an elevation of approximately 2010 metres on the upper northeast slopes of Big Timothy Mountain, approximately 500 metres southeast of the Silver Boss shaft (MINFILE 093A 019) and 300 metres northeast of the Dogtooth zone. The zone comprises an area of mineralized float boulders of hornblende granodiorite with disseminated pyrite, chalcopyrite and minor molybdenite in an area of intense epidote-chlorite veining in altered hornblende diorite hosting pyrite with minor chalcopyrite, molybdenite and magnetite. Alteration minerals include pervasive chlorite and carbonate with local potassium feldspar and biotite. A hornblende porphyritic quartz diorite dike cuts the diorite and hosts minor chalcopyrite and molybdenite along the contact zone. The dike strikes 046 degrees and dips 45 degrees southeast.

In 1995, a sample (DR17) of the dike contact zone assayed 0.62 gram per tonne gold, 14.4 grams per tonne silver and 0.046 per cent molybdenum, whereas samples (DR15 and DR16) of mineralized float assayed up to 1.18 grams per tonne gold, 65.0 grams per tonne silver, 1.09 per cent copper and 0.075 per cent molybdenum (Assessment Report 24208).

The 10 Mile Creek zone is located downslope, approximately 800 metres to the northeast and near the base of a steep east-facing slope below the headwaters of 10 Mile Creek. The zone is comprised of intensely fractured and sheared biotite hornblende quartz monzodiorite with quartz-, chlorite-, epidote-, pyroxene- and sericite-filled fractures hosting trace to massive pyrite and trace scheelite.

In 2005, a 4.0-metre-long chip sample assayed 0.21 gram per tonne gold, 0.001 per cent molybdenum and 0.015 per cent tungsten (Assessment Report 28344).

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.

During 1993 through 1995, the area was prospected and sampled as the Silver Boss and Peridote claims by Pioneer Metals Corp. In 2000, the area was prospected by D.W. Ridley.

During 2004 through 2014, Happy Creek Minerals carried out programs of prospecting; geological mapping, 34.2 line-kilometres of 3D induced polarization and magnetic geophysical surveys and stream sediment, soil and rock geochemical surveys on the area as the Silverboss property.
