Capsule Geology

The Homestake and Molly Gibson are ajoining claims on the north side of Jamieson Creek about 25 kilometres north of Kamloops.

Brownish weathering, highly fractured porphyritic quartz monzonite intrudes biotite and sericite schist and argillite of the Paleozoic to Mesozoic Harper Ranch and/or Nicola groups. In some areas the metasediments have been sheared and dragfolded. A northwest striking zone of shearing about 9 to 15 metres wide is well defined in the quartz monzonite intrusion where several near-parallel quartz veins and branching stringers occur along joint planes and prominent fractures. The veins traverse both the intrusive rock and metasediments. The veins are mineralized with scattered grains of pyrite, galena, arsenopyrite and sphalerite. The veins strike 330 to 345 degrees and dip from 90 to 60 degrees west and vary in thickness from 0.15 to 5.4 metres. Most of the veins (at least five) occur on the Homestake claim and continue to the south through a portion of the Molly Gibson claim. A sample from the dump of an opencut on a vein analysed 13.7 grams per tonne gold and 308.5 grams per tonne silver (Minister of Mines Annual Report 1930).

Several shafts (2.4 to 23 metres deep), an adit 45 metres long, numerous cuts, trenches and pits explore several quartz veins on both claims with most of the work conducted on the northerly Homestake claim.

The Homestake is one of the oldest known gold-quartz properties in the province, having been reported upon by G.M. Dawson in 1888.
