The Poppa Bear area is underlain by andesitic rock of the Upper Triassic Stuhini Group. A pluton of Triassic to Jurassic diorite to granodiorite intrudes the strata the a few hundred metres to the southwest.

The Poppa Bear Showing was discovered by Teck Corporation in 1991 during follow-up of anomalous results from its 1990 soil sampling program. The showing primarily consists of structures with high gold and copper contents, which lie within a 400 metre wide zone that extends along a strike length of 800 metres. The zone may be open to both the northeast and southwest, but its projections are obscured by talus. Where exposed, the zone is generally well fractured and encompasses numerous faults and dikes. The mineralized structures are discontinuous and irregularly shaped and are difficult to trace for any substantial distance. Mineralization is usually concentrated in fractures in the immediate hangingwall or footwall of the faults and dikes.

Chalcocite is the most common source of enhanced copper values within Poppa Bear Showing. It commonly coats fracture and joint planes but in some cases is found as weakly disseminated black spots that are especially visible in rhyodacite dikes. Chalcopyrite blebs up to several centimetres across occur in some of the wider fractures. Disseminated mineralization is rare and very local in occurrence. Malachite, and rarely azurite occur.

A sample is reported to have assayed 15.85 grams per tonne gold, 13.6 grams per tonne silver and 1.74 per cent copper over 3.5 metres from a dioritic dike with chalcocite, chalcopyrite and malachite (Pautler, J. (2019-05-31): Technical Report on the GK Project).
