This showing is about 2 kilometres northwest of the summit of Mount Thynne and 23 kilometres northwest of Tulameen.
The Dawn occurrence is hosted in a northward trending, steeply dipping sequence of andesitic flows, argillites, tuffs and limestone of the Upper Triassic Nicola Group, immediately southwest of a diorite stock of Late Triassic to Early Jurassic age.
Mineralization is exposed in three small pits over a 9 by 6 metre area in dark grey-green lava (andesite). Magnetite occurs as massive pods and disseminations, together with disseminated chalcopyrite and pyrite. Some calcite and epidote are associated with this mineralization. Considerable malachite staining is present on surface. A grab sample assayed trace gold, 20.6 grams per tonne silver and 0.45 per cent copper (Property File - J.P. Elwell, 1964, page 11, sample 6139). A second sample assayed trace gold, 5.1 grams per tonne silver and 0.05 per cent copper (sample 6141).
In 2014, exploration work along the Thynne Ridge area, located approximately 1 kilometres northeast of the Dawn occurrence, identified weakly developed skarn zones occurring over an area of more than 600 metres and comprising epidote-chlorite–altered Nicola volcanic rocks in contact with leucocratic granite and diorite hosting local pyrite, magnetite and chalcopyrite with very minor garnet and actinolite. Select samples (272616 to 272622) of pyrite-magnetite–rich material with visible chalcopyrite from a historical pit yielded up to 0.432 per cent copper (Assessment Report 35095).
Work History
In 1964, Bardale Mining and Development Co. Ltd. completed a program of prospecting, rock sampling and a 52.8 line-kilometre ground magnetic survey on the area as the B and R and Dawn claims.
During 2006 through 2014, Bryan and Egil Livgard completed programs of prospecting, geochemical (silt, soil and rock) sampling and biogeochemical sampling on the area as the George property.
During 2014 through 2018, Tech-X Resources Ltd. completed programs of geological mapping, geochemical (rock, silt and soil) sampling, 29.5 line-kilometres of induced polarization surveys and a 548.9 line-kilometre airborne magnetic survey and on the area as the Thinne and LC claims of the Lawless Creek property.
