The Anyox-Rodeo showing is situated at the Wann River, 2 kilometres southeast of Taku Arm of Tagish Lake.
The Anyox-Rodeo area is underlain by the Upper Triassic Stuhini Group and Devonian to Middle Triassic Boundary Ranges Metamorphic Suite rock intruded by Early Cretaceous foliated diorite to monzodiorite.
A copper-nickel occurrence, called the Anyox-Rodeo, is shown on Geological Survey of Canada Map 19-1957. This may correlate with an adit and pit beside a dam on Wann River and a second adit upstream, shown on a map in Assessment Report 1628.
In Bulletin 105, the showing is described as a copper-nickel-platinum-palladium massive sulphide lens hosted within rock of the Boundary Ranges Metamorphic Suite consisting of chlorite-actinolite schist near its contact with Upper Triassic Stuhini Volcanics. Fractured actinolite porphyroblasts up to 3 centimetres are accompanied by interstitial or fracture filled pentlandite, pyrrhotite, chalcopyrite, and pyrite. Precious metal values seem erratic and not reproducible. The deposit may be an example of basaltic copper (M01) or marine volcanic associations (G04/06).
A sample taken by the B.C. Geological Survey assayed 0.15 per cent copper, 0.60 per cent nickel, and 0.12 per cent cobalt (Open File 1990-4).
Work History
It is not known when the property was staked, however, some work was done prior to 1913. The Brownie Nos. 1, 3, 4 and 5 claims were owned by Messrs. Dunham, Nichol, Kerslaw, and Gilmore in 1918. Development work consists of open cuts and a short adit.
In 1968, Idaho Silver mines conducted a ground electromagnetic and magnetic survey over parts of the Wann River area, including the Anyox-Rodeo area. Several conductors were reported to have been outlined in the vicinity of old workings (Assessment Report 1628).
In 2007, prospecting was done on behalf of Opes Exploration Inc. The historical MINFILE showings (Brown 104M 026 and Anyox-Rodeo 104M 017) were located and the Brown showing was sampled and some hand sorted high-grade vein material was assayed. The Anyox-Rodeo showing was also sampled but not assayed. Rock samples from the Brown showing ranged up 300 grams silver, 1.22 per cent copper, and 1.60 per cent lead, however the vein material represented a narrow width (5 centimetres) of actual vein (Assessment Report 29811).
In 2007, Blind Creek Resources conducted a mobile metal ion soil survey in the Anyox-Rodeo area.
In 2008, Blind Creek completed a geochemical reconnaissance sampling program in the Wann area. The 2008 survey confirmed the anomalous results from the Anyox-Rodeo showing. The showing was visited in 2008. A grab sample from a 10-centimetre-wide massive pyrrhotite vein indicated anomalous values in gold (0.11 grams per tonne), copper (0.67 per cent), platinum (0.14 grams per tonne), palladium (0.2 grams per tonne), cobalt (0.11 per cent), and nickel (0.4 per cent) (Assessment Reports 31376, 32403).
In 2009, Blind Creek collected sample 9BCRWRO5R from old trenches along the shore of Tagish Lake, 180 metres west of the Wann River delta. A magnetometer survey was conducted in the area. Sampling extended to the Anyox-Rodeo area with one sample yielding 0.14 per cent copper (Assessment Report 32004). At the Anyox-Rodeo showing, an old pit with massive pyrrhotite fragments occurs. The fragments host minute specks of chalcopyrite. Immediately down slope in the canyon above the Wann River, short adits had been worked to trace the strike of the pyrrhotite. These were not sampled due to difficult access.
In 2010, a total of 89 rock - and 55 soil samples were collected in the Wann area including the Lum showing (Assessment Report 32004). A 10-kilometre magnetometer survey was completed.
In 2011, Blind Creek Resource completed a 17-hole drill program on the Brown prospect (104M 026), which was part of their Wann project.
In 2017, (MMI) soil sampling surveys were completed in the Engineer Mine (104M 014) and Wann River areas at the southern end of Tagish Lake (Assessment Report 37082). In the Wann River area, gold-silver-base metal veins have been the focus of historic work and were drilled in 2011. Occurrences in the Wann River area include Anyox-Rodeo (104M 017), Brown (104M 026), and Lum (104M 109). The geology of the area was examined and compared to the Engineer system; MMI samples were collected along the southern extension of the known veins as well as to the east, exploring the extensions of this zone toward the Llewellyn Fault. The sampling in the Wann River area included 195 samples along 6 lines. The lines were east-west and extended across the Wann River, testing the eastern and southern extensions of the area. Line spacing was 200 metres and sample spacing was 25 metres. The MMI survey outlined the extent of the younger intrusive body that may be important either genetically, or structurally, to vein emplacement. Several widely spaced anomalies warranted follow-up prospecting work and possibly with a further, more detailed, MMI survey to develop vein targets to the south and west of the known zone. The MMI lines are approximately 600 metres to the northwest of the Anyox-Rodeo occurrence.
