About the project
The project area covers the southerly extension of the favourable geology that hosts the deposits to the north. Running southerly, down the middle of the Crown property, is the “Kyba Red-Line”, which is a recognized geologic feature to which many of the major deposits in the region are spatially related. There are a number of known mineral occurrences at the Crown project, comprised of high grade Au-Ag veins and massive sulphide boulders, but to date there has been little modern exploration or drilling done to test the extent of these zones.
In the central part of the Crown claim block, the Orion showing consists of a stockwork zone of quartz-pyrite-arsenopyrite veinlets and sulphide fracture fillings. Veinlets are generally 1 to 10 centimetres wide with coarse pyrite and patchy arsenopyrite. The arsenopyrite typically comprises 2% to 4 %, and locally up to 20%, of the narrow sulfide stringers. Host rocks are felsic volcanics and carbonaceous sedimentary rocks, underlain by andesitic agglomerate and tuff, with nearby small syenite stocks. The largest, most intensely fractured zone is at least 15 metres wide within the more extensive stockwork area that is exposed over a length of about 40 m. Trenching of the stockwork zone in 1994 returned 2.54 g/t Au, 1.36 % As across 13 m of brecciated rhyolite.
The Tribe showing, located 1 km north of Orion, is within a sequence of chert, andesite agglomerate and tuff intruded by small syenite stocks. Areas of strong sericitic alteration contain quartz-carbonate veins and stockworks that locally carry pyrite, pyrrhotite, arsenopyrite, sphalerite, and galena. The best gold assay was from samples of a 13 by 30 metre stockwork zone, reported as 12.5 g/t Au and 3.1 g/t Ag over 0.4 m.
The Fairweather Zone, in the southeastern part of the claim block, is underlain by dacitic to andesitic volcanics and fine-grained sedimentary rocks intruded by feldspar porphyry bodies. Trenches have exposed mineralization consisting of quartz-calcite veins with galena, sphalerite, tetrahedrite, chalcopyrite, and pyrite carrying gold and significant amounts of silver. En echelon veins, up to 60 cm wide, occur within northeast-trending shears surrounded by zones of ankerite alteration. A pyritized structure between 5 and 15 metres in width, with a 125 m strike length was sampled, yielding a weighted average of 4.04 g/t Au over a 7.15 m width. A 2.0 m trench channel sample from a tetrahedrite-rich shear returned over 2000 g/t Ag.
In the eastern part of the project area, the Delta occurrence and other nearby showings are hosted by Middle Jurassic siltstone and intermediate volcaniclastics, with nearby small Eocene feldspar porphyry intrusions. Broad zones of strongly gossanous ankerite-sericite alteration contain cm-scale quartz-sulphide veins, up to 10 cm wide and dipping generally to the northwest, that have returned up to 13.7 g/t Au with significant Ag, Cu, Pb, Sb and Zn values.
Historic soil sampling has defined an extensive area, about 500 m in diameter, of anomalous Au, As, Pb, Sb and Zn at the Delta Northeast zone. The source of this large anomaly has yet to be defined, but the geological environment is favourable for Eskay Creek-style mineralization, similar to fine-grained stratiform Pb, Zn, Ag-rich mineralization found in siltstone at the 4-J showing, located about 4 km south of the project.
The Electrum property covers approximately 650 hectares and is located directly between the past producing Silbak Premier mine some 25 Km south and Pretium Resource’s Valley of the Kings deposit (production commenced in 2017) some 20 Km to the north. A well-developed 40 km road directly links the property to the bulk tonnage shipping terminals in Stewart. Electrical power lines come within 18 km of the property and can be continued along the existing haul road. The past producing Big Missouri mine is also located 14 down the haul road from the Electrum Property.
Mineralization on the Electrum property is controlled by two major fault lines that locally host bonanza type gold grades along with broader stockworked zones within a complex geological model. Like the nearby Valley of the Kings deposit, gold and silver mineralization occurs as coarse electrum in several generations of quartz-carbonate veins and vein breccias hosted within a deformed island arc-related sequence. The intermediate to low sulphidation mineralization is present in most of the veins with pyrite, sphalerite, galena and chalcopyrite. Precious metal mineralization has been traced on surface over lengths of several tens of meters to over a hundred meters, pinching and swelling along strike. Drilling has encountered gold-silver mineralization at depths greater than 200 metres from surface. The Electrum property hosts the historic East Gold mine where intermittent small-scale production between 1939 and 1965 produced 3,816 oz of gold and 2,442 oz of silver from 45 tons of hand selected ore (BC Minsitry of Mines Assessment Report 30206a).
Between 2006 and 2007 a total of 66 diamond drill holes comprising 15,369 meters was completed (American Creek Resources Ltd. Press Release June 6, 2007, December 11, 2007 and March 16, 2008, BC Ministry of Mines Assessment Report 30206a). Multiple targets were tested and significant values have been returned, such as 31.40 g/t gold and 19.0 g/t silver over 2.0 meters and 440.8 g/t gold and 400.0 g/t silver over 0.52 meters.
Targeting High-Grade Gold
Tudor is currently evaluating the potential for outlining a high-grade zone of mineralization similar to the Premier and Brucejack projects. The Electrum property has potential for high-grade gold-silver mineralization in epithermal breccia-vein systems that consistently follow a 120-130 strike direction.
These types of results have been confirmed in drilling where epithermal breccia veins were intercepted like the drill intercept og 440.78g/t Au over 0.52 meters (EL06-18), or high silver values such as 583 g/t Ag and 2.44 g/t Au over 0.30 meters;(EL07-09); EL07-12 (420g/t Ag and 4.88g/t Au over 0.91 meters); EL07-18 (374g/t Ag and 7.00g/t Au over 0.65 meters) and EL07-09 (384 g/t Ag and 2.49 g/t Au over 0.70 meters).
