The Cash showing area is underlain by the Upper Triassic King Salmon Formation, part of the younger Upper Triassic Stuhini Group, intruded by a quartz dioritic stock of the Late Cretaceous Windy Table Complex.

In 2016, it was observed that a large gossanous area is cross-cut by a notable east-west trending lineament approximately 500 meters to the northeast of the Eureka Trend (see 104K 090). In 2016 the area received very limited prospecting from the J2 Syndicate Holdings yet located arsenopyrite-pyrite-quartz stockwork within a silicified fault contact between fine grained quartz diorite and mafic volcanics, approximately 0.5 metre wide yielding 0.49 gram per tonne gold, 8.9 grams per tonne silver and 1.16 per cent lead, 0.2 per cent zinc (Sample S321040, Assessment Report 37087, Appendix C). The sample contained about 15 per cent pyrite and a trace of sphalerite. Sulphides are hosted in quartz-carbonate veins, striking 270 degrees and dipping 58 degrees north, hosted by altered intermediate fine-grained volcanic and very fine-grained aphanitic felsic volcanic rock (rhyolite?).

The area paralleling the Eureka Trend holds potential to host multiple polymetallic mineralized zones as large paralleling structures have been noted over 500 meters north across strike.
