The Silver Crown property consists of sedimentary and volcanic units of the Hazelton Group, where the Betty Creek and Mount Dilworth Formations gently folded and dipping the north west. These are then unconformably overlain by siltstone to mudstone sedimentary beds of the Spatsizi Formation. Prospective mineralization occurs in a large vein system generally striking north through the property with a length of at least 1.6 km dipping very steeply to the north-west. Veining is seen outcropping in both the Spatsizi and Mount Dilworth Formations. Veins are polymetallic with strong sulphide mineralization of pyrite, galena, sphalerite +\- chalcopyrite +\- trace malachite. 2019 grab samples from the vein system produced assays of up to 9.28 g/t Au and up to 1.4% Cu.

2020 Field Work
During the 2020 field season approximately 102 channel samples were taken at ~40 m intervals covering 0.5 km strike of the most prospective surface outcropping of the vein system.
Figure 2: Completed channel samples of quartz breccia veins. C0017617 contained 4% blebby galena and 3% pyrite. C0017615 contained 10% fine to coarse grained pyrite and 3% coarse grained galena.

Field mapping was also conducted to produce a more detailed understanding structural and lithological controls on mineralization; this helped confirm historic mapping of the vein system 500m to the north. Mapping was also completed surrounding the Iron Cap showing to better asses the area as a future target. This data is being compiled into a detailed map/model which will then be combined with the assay results of channel samples and outcrop grabs to delineate future drill targets.
