The ALDIE polymetallic showing is located on the east side of Franklin Creek, approximately 1.2 kilometres west of Mount Franklin.
The showing consists of sulphide mineralization in quartz veins and as replacements in north-trending, steeply dipping limestone lenses of the Devonian-Triassic Harper Ranch Group. Galena, sphalerite and chalcopyrite are inferred from silver, lead, zinc and copper assays (Assessment Report 17273). Nearby, rusty-weathering, siliceous, fine-grained clastic sediments contain abundant fracture controlled pyrite. The Harper Ranch Group includes argillite, siltstone and chert in this area. 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 ALDIE claim was Crown granted as Lot 3239 to Leonard Vaugham in 1905. Early records of work on the property are lacking, but an adit on the property existed prior to 1915.
In 1974, Falconbridge Nickel Mines limited carried out a soil geochemical survey over the area around an adit on the adjacent JIMMY (082ENE042) showing. Two areas of anomalous silver-lead geochemistry were identified.
In 1986, Longreach Resources Ltd. staked and optioned much of the Franklin camp area, including the ALDIE 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 ALDIE and JIMMY (082ENE042) showings. Placer drilled 2 diamond drillholes (87-36 and 87-37) on the JIMMY showing, about 75 metres to the northwest. Both drillholes intersected a deformed package of fine clastic sediments. No quartz veins or mineralization was intersected. Samples from the ALDIE showing contained several anomalous lead-zinc-silver assays; sample number 17096 assayed 0.47 gram per tonne gold, 8 grams per tonne silver, 0.95 per cent zinc, 0.42 per cent lead and 0.0295 per cent copper (Assessment Report 17273).
