The Eagle Creek zone is located on the eastern slopes of Quattrin Creek at approximately 1450 metres elevation, south-southeast of Yehiniko Lake.
The area is underlain by Upper Triassic volcanic rocks of the Stuhini Group consisting mainly of massive feldspar- and/or pyroxene porphyritic andesitic flows with lesser intercalated beds of siltstone, lapilli tuff and volcanic conglomerate. The beds generally strike northwest and dip moderately to the southeast. The package is not highly deformed, although it is possible that north trending, vertical faults crosscut the area. Locally, propylitic, silicified and K-feldspar altered intermediate to basaltic volcanic flows, welded crystal tuff, and various hypabyssal phases of a composite tonalite intrusion host quartz-carbonate filled fractures and veins containing chalcopyrite and pyrite with minor bornite, sphalerite and galena mineralization with localized coarse native gold. Throughout the Yeti property area, the veins vary from 0.01 metre to over 1 metre in width, as at the Crow vein (104G Blizzard).
Various large intrusion surround the Stuhini rocks in the Yeti area. Tonalite intrusions of the Middle Jurassic Three Sisters Plutonic Suite occur to the north and south, granodioritic intrusions of the Late Early Cone Mountain Plutonic Suite occur to the southwest, and a large unnamed Middle to Late Triassic quartz dioritic intrusion borders the Stuhini rock on the east.
The ultramafic “Yeti” body is in contact with the Stuhini rocks on its west and north and with the large unnamed Middle to Late Triassic quartz dioritic intrusion on the east. The “Yeti” ultramafic complex is a relatively small elongate intrusive body related to the Middle to Late Triassic Polaris Ultramafic Suite. This suite is an Alaskan-type intrusion that comprise a series of mafic-ultramafic complexes concentrated in northern British Columbia. The geochemical survey reported by Toscana Resources in 1990 (Assessment Report 21168) straddled the northern part of the “Yeti” body.
In 1990, Coast Mountain Geological and Quest Canada Exploration Ltd. performed a reconnaissance stream sediment survey, revealing several multi-element anomalies from tributary streams of the West Yehiniko and Yehiniko rivers. In 1992, Toscana Resources completed a program of prospecting, geological mapping and sampling on the Yehiniko property. This work outlined an area, 1600 metres long by 1200 metres wide, containing strong copper and gold. Toscana described the Eagle Creek including the lower west side of the Main Ridge, from the Comfort Zone to the Blizzard Zone. Quartz- carbonate veins and shears containing pyrite, chalcopyrite, and locally bornite, sphalerite and galena occur within silicified, chlorite-epidote, and locally K-feldspar altered volcanic rocks. Limited work has been done on this side (west) of the Main Ridge. Rock chip sample 92K-048 yielded 0.42 per cent copper and 1.36 grams per tonne gold across 3.0 metres and nearby chip sample 92K-051 assayed 0.38 per cent coppe, 4.5 grams per tonne gold, 6.6 grams per tonne silver, 2.2 per cent lead and 2.1 per cent zinc (Assessment Report 22773).
Work History.
In the early 1990s Schellex Gold Corp. and various other junior mining companies (including Toscana Resources) carried out reconnaissance scale prospecting and sampling in the area referred to as the Yeti Prospect. Shellex reportedly identified a north trending, 300 hundred meter wide quartz and carbonate stockwork zone with copper and gold mineralization that was traced for over 600 meters.
In 1990, Coast Mountain Geological and Quest Canada Exploration Ltd. performed a reconnaissance stream sediment survey, revealing several multi-element anomalies from tributary streams of the West Yehiniko and Yehiniko rivers. In 1992, Toscana Resources completed a program of prospecting, geological mapping and sampling on the Yehiniko property.
In 1995, Econ Ventures Ltd. conducted exploration on their Yehiniko property which included the Yeti 4 to 14 claims which were under option. During this program 64 rock and 198 soil samples were collected. Zones of most significant interest were in an area known as Goat Ridge which included: the Yeti or Main Zone (104G 194), the Comfort Zone (104G 196), the Eagle Creek Zone (104G 197), and the Blizzard zone (Crow vein).
In 2018, owner Carl Von Einsiedel arranged for a high resolution helicopter-borne aeromagnetic and radiometric survey to be flown over the Yeti Block, including the Eagle Creek zone. It consisted of 78 line kilometres, including 71 line kilometres flown at an orientation of 002/182 degrees and 7 kilometers of tie lines flown at 092/272 degrees. The line spacing was 200 meters and the survey was flown at an average survey height of 50.7 meters above terrain. Also in 2018, in order to verify the reported high nickel values from 1990, the current owners collected 9 rock and soil southern boundary of the 1990 soil survey grid.
