The Anuk RB 12 showing is located approximately 43 kilometres north-northeast of the confluence of the Iskut and Stikine rivers.
The Anuk RB 12 area is underlain by Upper Triassic marine sedimentary and volcanic rocks of the Stuhini Group and an Early Jurassic monzodioritic to gabbroic pluton of the Texas Creek Plutonic Suite in contact with Stuhini rock to the west. Unnamed Upper Triassic to Lower Jurassic alkaline volcanic rocks are mapped in the vicinity of Anuk RB 12. These may consist of coarse pseudoleucite and pyroxene, feldspar flows and breccias interlayered with orthoclase feldspar, biotite crystal tuffs and epiclastic units, including thick polymictic volcanic conglomerate horizons.
The north-south collection of mineralized samples described below were taken across the contact of Stuhini rock with rock of the Triassic-Jurassic alkaline volcanics, as shown on regional geology maps (see MapPlace).
In 1990, Schellex held the Anuk property consisting of the RB 12, 14, 16 and 18 claims. Six of 9 outcrop samples taken on the RB 12 claim, over a north-south distance of about 1.5 kilometres, yielded significant values in copper and gold. Halfway between the most southern and northern samples, a sample of narrow quartz-calcite vein with 10 per cent bornite graded 12.42 per cent copper, 0.9 gram per tonne gold and 106.3 grams per tonne silver (Sample K06, Assessment Report 21146). Sample C122, about 300 metres southwest of sample K06, a chloritic volcanic with 2 per cent chalcopyrite assayed 1.54 per cent copper and 11.5 grams per tonne silver; four other samples were at or greater than 0.31 per cent copper (Assessment Report 21146).
In 1991, Wirlwind Resources Ltd described Zone 1 as “consisting of sheared and potassium-feldspar altered volcanic rocks that trends 040 and dip subvertically to steeply westward. The rocks are notably fissile and extend from the northeastern edge of the property southwest towards the Anuk glacier, a distance of approximately 1.5 kilometres (Figures 2, 9, 10, Assessment Report 22035). A parallel zone of moderate quartz- potassium-feldspar alteration occurs 10-20 metres to the west of the strong potassium-feldspar altered zone, and a strong 2-3 metre wide shear occurs 100 metres further west. These zones are dominantly chlorite-quartz- potassium-feldspar altered and contain variable amounts of pyrite-chalcopyrite mineralization with traces of galena.”
“The potassium-feldspar altered zone is characterized by white to weakly rusty weathering pyritic-hematitic fine-grained chocolate brown tuff. The rocks are very hard and appear intensely silicified. The intensely altered zone averages about 10-12 metres in width and has been traced for 200 metres. The zone is traceable beyond this with a lower degree of alteration. Sulphide content is generally 0.5-1.0 per cent very fine-grained pyrite and hematite with minor chalcopyrite and traces of galena. The zone is cut by 1-10 millimetre wide white to grey quartz- potassium -feldspar (locally amethystine? or possibly cancrinite) fracture fillings forming stockwork and locally weak breccia. Two types of veining were noted; quartz-potassium-feldspar veinlets and potassium-feldspar. The veinlets locally contain hematite, pyrite and minor chalcopyrite and galena. Quartz- sericite-pyrite alteration forms a 0.5-5.0 metre halo around the feldspathized zone, with the sulphide content reaching 5-10 per cent locally towards the south, where the zone begins to narrow. In the vicinity of the shear zone several samples containing hematite, pyrite and traces of chalcopyrite returned gold values up to 1 gram per tonne (Assessment Report 22035). Most of the samples taken within this zone yielded elevated barium values."
WORK HISTORY.
During 1966 and 1967, Anuk River Mines Ltd. mapped, trenched and backpack drilled 695 feet on the Devils Club showing on Saddle Mountain 3 kilometres northwest of the Anuk property.
In January of 1989, the RB 12, RB 14, RB 16 and RB18 claims were staked and later grouped under the name Anuk. In the fall of 1989, Shellex Gold Corp. prospected and surface sampled portions of the Anuk property which resulted in several mineralized quartz veins being discovered. A total of 37 rock samples and 3 stream sediment samples were collected for analysis. A number of samples were taken in the area of the Joan and MB (104G 047) occurrence plot.
In 1990, Schellex held the Anuk property consisting of the RB 12, 14, 16 and 18 claims. Work consisted of prospecting, surface sampling and geological mapping. A total of 19 rock, 8 soil and 7 silt samples were collected. Three MINFILE showings, including the Anuk RB 12 were defined as a result of the work.
In 1991 Over 350 chip, chip-panel, grab and float samples were taken during the program by operator Wirlwind Resources Ltd with Schellex Gold Corp as owner. During this time a program of mapping and sampling on a scale of 1:10,000 was performed.
