The Geology and Mineralogy of the JC Tin Skarn, Yukon Territory, Canada

The JC deposit is a stanniferous skarn related to a ridge-like lobe of the mid-Cretaceous Seagull Batholith. Skarn replaces Mississippian carbonate sediments of the Yukon Cataclastic Complex along an elongate contact zone with a known strike length of 850 m. Tin mineralization was discovered at JC in 1977 and subsequent drilling has outlined estimated geologically inferred reserves of 1,250,000 t grading 0.54% Sn with a cut-off grade of 0.30%.
