Tuffisite breccia with banded quartz-adularia banding and discordant quartz-adularia veinlets, located in the central part of the airborne potassium anomaly and immediately adjacent to the targeted IP-resistivity anomaly coincident with high silver in soil. The groundmass is completely replaced by quartz and adularia, and overprinted by fine-grained sericite. The yellow colour is a positive stain for potassium using cobaltinitrite. Sample locations are shown in Figure 1.
