Work History

Early staking near this location included Mountain Chief, etc cl (4614) by J. McGilvray in Sep/1900 and Golden King cl (4803) by N. Williamson in Feb/01.
Restaked in Feb/82 by Don Lee as DL cl 1-72 (YA64924), which were transferred to Lee's Jade & Opal Ltd in 1985 and optioned to New Era Development Ltd and Havilah Gold Mines Ltd in 1987 and explored in conjunction with nearby placer activity.
Klondike Reef Mines Ltd staked the Gate cl 1-40 (YB31706) 5 km to the southeast in Nov/90. B. Kreft staked the Joel 1-2 cl (YB45602) nearby in Sep/93.
Restaked as RB cl 1-32 (YC94469) and cl 33-50 (YC88001) in Jun/2009 by B. Naughty. In Jul/2009 Naughty optioned the claims to Weststar Resources Corp. in return for cash, shares and certain work commitments. The company named the combined claim block the Golden Fox property and commenced a silt and soil sampling program in Oct/2009.

Capsule Geology

The geology of the Stewart River Area was remapped by J. Ryan and S. Gordey (2004) of the Geological Survey of Canada beginning in 2000 as a component of the Ancient Pacific Margin NATMAP Project. The NATMAP Project is an interagency project initiated by the Geological Survey of Canada, Yukon Geology Program (now Yukon Geological Survey) and British Columbia Geological Survey Branch to understand the composition, relationships and metallogenic of poorly understood pericratonic terranes lying between the ancestral North American margin and those known with more certainty to be tectonically accreted. The Stewart River component focuses on the Yukon-Tanana terrane, comprising complexly deformed mostly (?) Paleozoic meta-igneous and metasedimentary rocks. In 2005 S. Gordey and J. Ryan released a geological compilation map for the Stewart River area. The map units generally remained the same as the 2004 geology map but age dates were changed to reflect new dates obtained through geochronology data.
J. Ryan reported that the Stewart River area is underlain by twice-transposed, amphibolite-facies gneiss and schist of mostly (?) Paleozoic age. These are intruded by younger plutonic rocks (Jurassic, Cretaceous and Eocene) and overlain by upper Cretaceous volcanic rocks. Metasiliclastic rocks are widespread and dominated by psammite and quartzite, with lesser pelite and rare conglomerate. Preliminary detrital zircon geochronology and geochronology for plutonic rocks constrain the siliclastic rocks to the Middle Paleozoic. Amphibolite interdigitates with and stratigraphically overlies the siliclastic rocks. Marble horizons ((?) reefs) occurs within the amphibolite and siliclastic rocks. Orthogneissic rocks with diorite, tonalite and granodiorite protoliths intrude both the siliclastic and amphibole assemblages; it is interpreted as a subvolcanic intrusive complex.
Geological mapping by J. Ryan and S. Gordey shows the area surrounding the occurrence is underlain by Devonian to Mississippian intermediate to mafic orthogneiss that is commonly interlayered with amphibolite schist and gneiss. The orthogneiss is intruded by a small Eocene felsic porphyry body. Northwest of the occurrence the country rocks appear to change to amphibolite mixed with some orthogneiss. A major northwest-southeast structure (fault ?) crosscuts across the area.
The original claims were probably staked on gold bearing quartz veins. Several small, linear magnetic anomalies occur nearby.
Weststar Resources collected silt and soil sample along side three distinct drainage areas in the north, central and southern parts of the claim block. Analytical results from the silts identified an anomalous area approximately 850 m in length situated in the central part of the claim block that returned elevated gold values to 30 ppb.
