About the project
The Crown project covers approximately 18,300 hectares, located directly to the south of the world-class KSM gold-copper deposits and the new Valley of the Kings gold mine. 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, some that have had minor production from high grade Au-Ag veins, but to date there has been little modern exploration or drilling done to test the extent of these zones.
On the southwest part of the property several mineralized quartz veins occur in a shear zone that cuts andesitic tuff, siltstone and local intrusive rocks at the Doc showing. The veins contain 5 to 10 percent sulphide minerals with associated precious metals. Sampling in 1985 revealed that 170 metres of the main vein averaged 15.43 g/t gold and 59.6 g/t silver across an average width of 2.3 metres. In 1987, underground development, drilling and trenching was undertaken on seven veins, which led to calculation of a small mineral inventory averaging 9.26 g/t Au and 44.9 g/t Ag. In 1988, additional diamond drilling and underground development established potential for approximately 90,000 tonnes grading 8.8 g/t Au in the two main Doc veins. No further work, other than a prospecting program has been done in the showing area since that time.
The Globe showing, about 2 km to the southeast of Doc, contains similar veins ranging from one to 16 meters in width. In 1889 at Globe, 45 tonnes of vein material were mined from four short adits, but never shipped. Four or 5 other gold-bearing quartz vein showings are known within 2 to 5 km of the Doc veins, however, little work has been done on these veins.
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.
