The Lone Maid showing is located 2.0 kilometres north-northwest of Alice Arm, 750 metres north of the Esperanza mine (103P 126). The property (Lot 3191) was explored for the northward extension of the Esperanza vein during the early 1920s.

The area is underlain by Middle to Upper Jurassic Hazelton Group sediments. The sediments dip moderately to steeply southwest and northeast as a result of being deformed into closely spaced northwest-trending folds.

The showing comprises a zone, 0.30 to 1.52 metres in diameter, of quartz and calcite veining that strikes northeast and dips about 45 degrees northwest. The veins, up to 0.46 metre wide, crosscut southwest dipping (about 45 degrees) argillite. The zone has been traced, by tunnel, for 23 metres. Mineralization in the quartz and calcite veins consists of sparse pyrite, pyrrhotite, chalcopyrite, sphalerite and galena.

In 1916, the Lone Maid Crown grant was owned by G. Chambers. By 1923, a crosscut tunnel at 320 metres elevation was run in 23 metres at 235 degrees azimuth on a small zone of brecciated quartz, argillite and country rock about 1.5 metres wide. At 16 metres from the collar, a crosscut from this vein zone was driven 25 metres on a bearing of 280 degrees. It is reported that this crosscut to the right in the tunnel just about parallels the vein instead of crosscutting to it as intended. The drift straight ahead on the small cross vein followed by the tunnel should cut the main vein in a comparatively short distance.
