The Garnet occurrence is located on a northeast-trending ridge separating Texas and McRae creeks, approximately 3.5 kilometres northeast of the mouth of Texas Creek on Christina Lake.
The area is underlain by mudstone, siltstone, shale and fine clastic sedimentary rocks of the Carboniferous to Permian Mount Roberts Formation. To the north and west these have been intruded by Middle Jurassic granitic rocks and by syenitic to monzonitic rocks of the Eocene Coryell Plutonic Suite to the south. The zone has been followed intermittently by pits and trenches for approximately 240 metres along strike with the best mineralization exposed in the two northern pits over a distance of 60 metres and a width of 9 metres.
Locally, irregular, sill-like bands of disseminated molybdenite-bearing quartz are reported in a paragneiss host, which has been intruded by a coarse biotite-rich granite. The granite also hosts scattered molybdenite mineralization. The paragneiss strike to the north and dips 15 to 30 degrees east.
In 1957, sampling from the main quartz band yielded from 0.1 to 3.9 per cent molybdenum with an average of approximately 0.6 per cent molybdenum over 0.6 metre, whereas samples of the granite yielded 0.1 per cent molybdenum (Property File - McDougall, J.J. [1957-12-19]: Report on Barriere Molybdenite and Christina Lake Molybdenite).
In 1969, Brycon Explorations Ltd. conducted an 87 line- kilometre airborne magnetometer survey over the Herb, Moly, Garnet, Ruby and Jack claims. Previous geochemical soil and self-potential surveys located anomalies that, when investigated by diamond drilling, revealed that copper and molybdenum was present in some bedrock areas.
