The mineralized zone is located directly under a well developed placer area with a long history of production dating back to the late 1800s. A 26-metre shaft was sunk on the property in 1903 and reported to hit free gold but the shaft was filled with placer tailings and has not been located since. It was reported that the gold was hosted in quartz-filled fissures at mineable widths. A shallow thrust along the southern slopes of Mount Munro and capping Spruce Mountain hosts many showings. A later steep fault along Pine Creek valley is also seen in showings. The Yellow Jacket occurrence consists of a zone of quartz veins, breccia and silicified patches located within intensely altered and sheared upper Mississippian to Permian Cache Creek Complex ultramafic rocks. The ultramafics are bounded above by light green, hornblende feldspar porphyritic andesite and below by a darker green, and more massive andesite to basalt of the upper Mississippian to Permian Nakina Formation (Cache Creek Complex). The contacts are highly sheared and altered, often having slickensides. Around the contacts, the basalt is heavily chlorite altered and the ultramafic is altered to serpentine, fuchsite, talc, quartz and carbonate (listwanite assemblage). The talc/serpentine zones often grade into intense silicification. Within the ultramafic zone, there are abundant interbedded sequences of andesite/basalt. Shearing and alteration has occurred preferentially along the contacts of the interbedded mafic and ultramafic rocks. The auriferous zone occurs near the top of the ultramafic zone which may define a fault zone. The zone is 3 to 4 metres wide with narrow quartz veins containing free gold within breccia and silicified zones. Pyrite, chromite and fuchsite occur as minor accessories. Samples from this zone have analysed 15.1 grams per tonne gold over 4.0 metres and 17.8 grams per tonne gold over 3.1 metres (Vancouver Stockwatch - March 11, 1987). Minor magnesite is found in the auriferous zones. Drill programs conducted by Homestake Mining Company in 1986 and 1987 have defined the mineralized zone over a 226 metre strike length with ore grade intercepts to 91 metres in depth. The favourable structure has been drill indicated over 2 kilometres and to a depth of 183 metres (George Cross Newsletter, No.213, 1988). In 1983, local area prospectors staked the area of the Yellowjacket property and then optioned the property to Canova Resources and Tri-Pacific Resources. During 1984 and 1985, these companies conducted programs of ground geophysics, rotary and diamond drilling. In 1986, Homestake Mineral Development Company optioned the property from Canova in joint venture and initiated programs of mapping, reverse circulation drilling and diamond drilling. In 1988, Homestake completed a ground geophysical program which consisted of 5.5 kilometres of magnetic (total field and measured vertical gradient) and VLF-EM surveys. A diamond drill program was conducted in which 23 drillholes, for a total of 3255 metres, were completed. A resource estimate was reported following this work, of 453,500 tonnes grading 10.26 grams per tonne gold (www.eagleplains.com, Open File 2000-2 page 41). In 1995, owners Brad White and Gary Lee conducted 7 kilometres of VLF-EM and magnetometer survey. Muskox Minerals Corp. optioned the property in late 2003 and began exploration in December of that same year to further outline the extent, nature, grade and geometry of gold mineralization. The zone does not outcrop, therefore geological information about the zone is obtainable only through the examination of diamond drill core. Two holes were drilled in December, the beginning of a 20-hole program that would continue in 2004. In 2004, two of twelve holes drilled by Muskox encountered coarse gold that yielded assay intercepts similar to those obtained by previous explorers. Drilling is reported to have totalled 3750 metres in the 12 holes. Muskox reported significant gold intersections of 513.5 grams per tonne over 5.56 metres in drillhole YJ03-01 and 128.15 grams per tonne over 0.5 metre in drillhole YJ04-01 (Press Release, November 15, 2004). In 2005, Muskox completed a 50 kilometre magnetic survey and, late in the year, resumed drilling. Six holes were drilled in the Yellow Jacket zone and 1.5 kilometres to the southwest, three holes were drilled in the Rock of Ages zone, for a total of 895 metres. Also in 2005, Prize Mining Corp. (formerly Muskox Minerals Corp.) reported the completion of a Technical Report on the property by consultant Linda Dandy, P.Geo., dated February 15, 2005. In 2007, Prize Mining commenced a bulk sampling project and has been processing material on site. In September 2008, the company announced the first shipment of a 6.842 kilogram gold bar. In 2010, Eagle Plains Resources Ltd. completed the purchase of Prize Mining's remaining interest in the Yellow Jacket Joint Venture and now holds 100%, subject to any underlying agreements. Based on the recommendations of a 2010 Technical Report, Eagle Plains carried out a reverse circulation drill program at the Yellowjacket in the fall of 2010. A total of 2181 metres in 64 holes was completed in the area of the proposed East pit extension. The results from the program are encouraging and further work is recommended to both better define mineralization for potential open pit mining operations and to test for mineralization both at depth and outside the area of the main Yellowjacket zone.
