Project Overview
The 109-claim (2,398ha) Jaycee property is 60km kilometers east of Teslin in southern Yukon. The claims, held 100% by the Jaycee Syndicate, were staked in 2018. Limited rock sampling and a 425-km airborne geophysical survey were completed in 2018. In 2019, 17 rock samples and 230 soil samples were collected. Previous work documented from 1967 to 2006, including geological, magnetic and soil geochemical surveys, and 18 hand trenches, outlined a 900m skarn horizon with significant tin mineralization on surface. From 1979 to 1982, 38 holes (4,168m) were drilled and the “JC Tin” deposit was defined along a surface trace of 750m.
Geology and Mineralization
The Property is in an area regionally underlain by layered Yukon-Tanana Terrane metasediments and metavolcanics of the Intermontane Tectonic Belt of the Canadian Cordillera. The layered rocks are intruded by mid-Cretaceous age Seagull Suite granites and monzonites. Locally on the Property, a thick sequence of quartzite is intruded by a narrow, ridge like lobe of granite that is not exposed at surface. A 30 to 40m thick carbonate horizon lies within the quartzite just above and in contact with the granite. Portions of the carbonate horizon have been altered to skarn and are tin-bearing. The skarn zone is traceable intermittently for 900m on surface. In drilling it varies from 20 to 38m thick. Mineralization within the skarn includes lenses containing various amounts of magnetite, arsenopyrite and pyrite, with lesser amounts of pyrrhotite, chalcopyrite and sphalerite. The tin minerals cassiterite and malayaite have been identified in grab samples as well as the tungsten minerals scheelite and wolframite. The tin mineralization occurs mainly as fine-grained cassiterite associated with various sulphides within actinolite-bearing zones of the skarn. Sampling in 2018 gave up to 17.96% Cu and 633.0gpt Ag at the Camp Zone, and 1.13% Sn and 7.3gpt Ag at the Lake Zone.
Polymetallic Skarn
Past exploration on Jaycee focused on tin only. In 2019, rock sampling along 800m of the JC skarn zone returned values up to 3.78% Cu, 12.93% Zn, 5.47% Sn, 147.0gpt Ag & 4.47% As from 5 distinct showings. Four styles of mineralization were noted. Jaycee, in addition to tin, clearly has potential for copper, zinc and silver in polymetallic skarn zones. Highly anomalous Cu, Zn, Sn, Ag & As in soils traced the JC zone westward up to a total length of 3000m on surface. This geochemical trend closely follows the northern margin of a magnetic high. This relationship provides a working model for further exploration whereby prospecting and soil sampling along magnetic highs may be used to locate polymetallic skarn zones. Detailed compilation shows previously outlined, strong tin-in-soil anomalies that provide immediate targets for geochemical and prospecting surveys in 2020.
