Jim McCrea P.Geo has reviewed and approves the information for the Austruck-Bonanza Property.
The Austruck-Bonanza Property is located within the Kamloops Mining Division 53 kilometers north west of the city of Kamloops in south central British Columbia. It lies within the southern extension of the Quesnel Trough (a heavily mineralized major trend through central B.C) and is contiguous with WestKam Gold’s Bonaparte Gold property to the south east.
Paved roads, power lines, telephone and other infrastructure follow the west side of the North Thompson River along the Westsyde Road corridor to within 15 kilometers of the property. A skilled labour force for mining and exploration is available in Kamloops. This is a clearcut forest area and therefore very accessible to exploration and development.
The earliest work recorded in the Ministry of Energy and Mines assessment report database was conducted in the late 1960’s, initially exploring for molybdenum potential and more recently for precious and base metals. Perhaps the most significant recent development in the area is within the Bonaparte Gold Property, located immediately south east of the Austruck-Bonanza Property.
Work on the neighbouring Bonaparte property has outlined the presence of a series of well-developed shear zones that contain numerous auriferous quartz veins. Intersections encountered in diamond drilling at the adjacent Bonaparte property include:
113.70 g/t Au over 0.87m
Two small open pits (Discovery Zone) on the Bonaparte property were excavated in 1994, yielding a 3,700 tonne bulk sample grading approximately 26.5 grams gold per tonne. Several high grade intersections were encountered in diamond drilling beneath the present bottom of the pit. Another small bulk sample of 364 tonnes was run in 2010 with an average grade of 16.28 grams gold per tonne. The rock was smelted down and the gold recoverd was sold to help pay for the program.
The image "Bonaparte Claims and Vein Systems" shows the common border (west side) with the Austruck-Bonanza property on the left and a blowup of the veins found in the "Discovery Zone" right along the border. The image below that shows Induced Polorization (IP) results south of the "Discovery Zone". The yellow line is the common border with the Austruck-Bonanza. The image of the pond below that is Bonaparte's "Discovery Zone" pit filled with water, taken from the Austruck-Bonanza propoerty.
The Austruck-Bonanza Property is underlain by Devonian to Triassic Harper Ranch formation comprised of fine grade sedimentary rocks including mudstone and shale, and includes basaltic volcanics.
The geology of the area represents an erosional window through Miocene Plateau basalts exposing the older underlying Devonian to Triassic metasediments and volcanics. These have been intruded by Triassic to Jurassic granodiorite and quartz diorite that is believed to be part of larger underlying batholiths. Several large faults crosscut the area subdividing it into separate structural domains.
The area of interest historically explored consists of fracture zones that cut the quartz diorite intrusions and the older country rocks. The fracture zones appear to be part of larger regional structural zones.
Mineralization in the Austruck-Bonanza property area is associated with shear and fracture zones that cut small intrusive bodies and surrounding sedimentary rocks. Mineralization is within quartz veins and stringers that are spatially related to the intrusive bodies. Sulphide minerals have been identified within the quartz veins, and in places within the surrounding host rocks.
Ore minerals that have been identified within the quartz veins and surrounding host rock include galena, sphalerite, pyrite, pyrrhotite, arsenopyrite, chalcopyrite, and molybenite. Minor native gold has been identified, as well as silver-grey tellurides. The mineralization style has been classified by previous workers as epigenetic, hydrothermal, gold-qartz veins.
Geophysics will be usefull in helping identify a continuation of the geological structures that lead up to common border with the Bonaparte mine.
American Creek has not independantly verified the information for the Bonaparte property and notes that results are not necessarily indicative of what may be found at the Austruck-Bonanza property.
