The Hidden Mystery gold mine is located 7 kilometres north north-west of Tennant Creek, on the northern boundary of the Mary Lane Shear Zone, a major regional east-west structure. In the mine area is found mudstones, siltstone, greywacke , but mainly shale of the Carraman Formation, with much quartz veining.

The Mystery mine workings are on magnetite/hematite ironstones, these becoming more jasperlitic and siliceous away from the mine. The ironstone forms a cylindrical shaped magnetic body, plunging steeply east south-east.

Foliated quartz-feldspar porphyry encloses jasperlitic ironstone lenses 300 metres east south-east of the old mine workings. A kaolinised quartz-feldspar porphyry intrudes the sedimentary rocks, 760 metres east of the workings.

Explored in the late 1980's, and 1990's by Metana Minerals, Roebuck Resources, Placer Exploration Ltd, and Posgold Ltd. BMR identified an anomaly 500 metres east of the old mine workings in 1969, they also call Hidden Mystery.

Mentioned in passing as developed by Charlie Priest in the 1930's. The mine only produced 11.5 ounces of gold at 15 g/t. Daniel Francis Laughlin took out the lease (GML 136E) in 1945.

Modat lists cassiterite at the location, although this is not a species commonly mentioned in the Tennant Creek area.

The site contains at least six shafts, and some shallow bulldozer scrapings. Bordering to the west appears to be a station homestead with several buildings.
