The JIMMY showing is located on the east side of Franklin Creek, approximately 1.35 kilometres west of Mount Franklin.

The showing consists of silver-lead-zinc-copper mineralization in quartz veins and as replacements in limestone lenses. The limestone lenses, of the Devonian-Triassic Harper Ranch Group, are north-trending and steeply dipping. Nearby, rusty-weathering, siliceous, fine-grained clastic sediments contain abundant fracture controlled pyrite. The Harper Ranch Group also includes argillite, siltstone and chert. About a kilometre to the south and to the west is an unnamed Middle Jurassic granodiorite intrusion. Syenite of the Eocene Coryell Intrusions is found approximately 1 kilometre to the north.

The JIMMY showing is located approximately where the FRANKLIN Crown grant, Lot 438s, was located. The FRANKLIN claim was at one time owned by Frank McFarlane but in 1914 the recorded owner was Mrs. Lindholm. Early records of work on the property are lacking, but an adit is thought to date from the early 1900s.

In 1964, Franklin Mines Ltd. acquired much of the Franklin camp and carried out geological mapping, sampling and magnetometer surveys over several mineral occurrences in the camp. Work was filed on the JIMMY and JIMMY FR. claims but no details are recorded.

In 1974, Falconbridge Nickel Mines Ltd. carried out a soil geochemical survey over the area around the adit and shaft. Two areas with anomalous silver-lead geochemistry were identified.

In 1984, Pearl Resources Ltd. held the JIMMY showing as part of a large property position they had assembled around the UNION (082ENE003) mine. No work was recorded on the JIMMY showing.

In 1986, Longreach Resources Ltd. staked and optioned much of the Franklin camp area, including the JIMMY showing. It is probable that Longreach prospected this area, although no reports specific to the showing were filed.

In 1987, Placer Dome Inc. optioned the PLATINUM BLONDE property from Longreach Resources Ltd., which included the JIMMY showing. Placer drilled 2 diamond drillholes (87-36 and 87-37) to test a northwesterly trending, mineralized quartz vein, which measured 1 - 2 metres in width. Both drillholes intersected a deformed package of fine clastic sediments. No significant quartz veins were intersected. The pyrite stockwork was found to be weakly anomalous in arsenic. A grab sample collected from the adit assayed 20 grams per tonne silver, 3.4 per cent zinc, 1.94 per cent lead and 0.027 per cent copper (Assessment Report 17273).
