Lady Franklin Mine, mine developed in 1887 on NS-orientated blue quartz veins trending 055, dip steep SE in host talcose, serpentinised shale of the Hutchison Group. Mine consisted of two shafts about 400 m apart developed. The lode trended 055, dipped steep SE. Ore minerals were patches of sulphides, mainly galena, sphalerite and minor pyrite, carrying silver and gold. The original workings of 2 main shafts ~400m apart have been backfilled. No production figures were determined. Samples sent to the Wallaroo smelters assayed 22%Pb, 47g/tAg, and <1g/tAu. Grab samples from the 23m level assayed 1.4%Pb, 6g/tAg, and trace only Au. Later exploration included geophysics, with follow up grid drilling. Results were not encouraging. Percussion drillhole 83WP2 penetrated a zone of primary, but sub-economic Pb-Ag-(Au-Zn-Cu) mineralization (galena, chalcopyrite, sphalerite, pyrite, marcasite and pyrrhotite) from 54-68m, and adjacent to a marble-phyllite contact. Only weak pyrite mineralisation was encountered in drill holes at the Moonlight mine, with the broad anomalous IP response in that area remaining unexplained.
