The YELLOW JACKET showing is located on reverted Crown grant Lot 924S, which is approximately 1.7 kilometres southeast of the summit of Mount Franklin.

The showing is hosted by marble and limestone of the Devonian- Triassic Harper Ranch Group. Nearby, the Harper Ranch Group also includes quartzite, argillite and greenstone. Mineralization consists of small pods and siliceous veins of chalcopyrite, galena, sphalerite, pyrite and magnetite. Alteration minerals include calcite, epidote, garnet, tremolite, chlorite and quartz.

The YELLOW JACKET claim was Crown granted as Lot 924s to M.K. Forbes and B. Leguime in 1912. No work is recorded on the property during the early 1900s when the Franklin camp was active.

In 1964, Franklin Mines Ltd. optioned the YELLOW JACKET from Northwest Ventures Ltd. and carried out some preliminary surveys of the area. The precious metal potential of the BUFFALO (082ENE008), GLOUCESTER (082ENE005), AVERILL (082ENE007), and MAPLE LEAF (082ENE009) adits was the main focus of their work; no work was filed on the YELLOW JACKET.

In 1977, Dallas Explorations Ltd. acquired the YELLOW JACKET reverted Crown grant and surrounding area. They carried out a small soil sample survey in the vicinity of the YELLOW JACKET, analyzing the samples for gold, silver and copper. Anomalous results were indicated, but the actual values and locations were not given.

In 1980, Pearl Resources Ltd. acquired the YELLOW JACKET reverted Crown Grant, along with much of the surrounding area, including the UNION mine (082ENE003). Most of their work was directed at developing the UNION mine, no work was filed on the YELLOW JACKET showing.

In 1986-87, Longreach Resources Ltd. and Placer Dome Inc. carried out a major platinum exploration program in the Franklin camp. There is no evidence that they carried out any work on the YELLOW JACKET showing.
