Nimbus LA-ICPMS images - September 2015

•Nimbus contains syn-sedimentary, diagenetic, and hydrothermal pyrite styles •Each style contains its own geochemical signature •Earliest pyrite is enriched in Ag, Zn, and Cu •Later (hydrothermal) pyrite is enriched in As, Au (up to 10 ppm), and Ag •Pyrite textures and geochemistry can be used in the Nimbus district to successfully vector toward Zn-Ag orebodies(and potentially overprinting Au-As orebodies, as well) •Further work required to flesh out extent of Au-rich pyrite
