The Hoodoo South occurrence consists of molybdenum and copper mineralization, and covers the western part of the Hoodoo Creek property. It is 4.5 kilometres west-southwest of the Hoodoo North occurrence (092N 029), 28 kilometres north of the head of Knight Inlet.

Amax Incorporation, through Amax Potash Limited, staked the property as the BZT 1 to 9 claims (103 units) with BZT 1 covering Hoodoo South and BZT 5-8 Hoodoo North. Work during 1977-78 included geological mapping and geochemical soil and rock chip surveys (515 samples). Subsequent work was under a 50-50 joint venture agreement with Utah Mines Limited. Canamax Resources Incorporated was incorporated in December 1982 to consolidate Amax's Canadian exploration interests; a 63.9 per cent interest in the new company was held by Amax of Canada Limited.

The occurrence lies within the Jurassic to Tertiary Coast Plutonic Complex, which locally consists of foliated quartz diorite, diorite and granitoid gneisses of probable Mesozoic age (Geological Survey of Canada Open File 1163). These rocks are intruded by coarse-grained quartz monzonite and fine to medium-grained granodiorite stocks. These rocks may also be Mesozoic, or of Tertiary age if they are related to the Miocene intrusions at the Hoodoo North occurrence. Mineralization is largely restricted to the quartz monzonite stock, and consists of several molybdenite showings over an area of 500 by 500 metres. The intrusion of the stock was partly fault controlled: its contact with the dioritic rocks and gneisses is marked by breccia zones. These zones contain up to 5 per cent disseminated pyrite in the matrix, and very minor chalcopyrite. In the interior of the quartz monzonite, mineralization comprises mainly veins or widely-spaced fracture coatings containing quartz-pyrite, pyrite, quartz-molybdenite, or quartz-molybdenite-chalcopyrite. One spectacular quartz-molybdenite-pyrite-chalcopyrite vein, 10 centimetres wide, consists of at least 90 per cent sulphides, of which 50 per cent is coarse rosettes of molybdenite (Assessment Report 8218). Molybdenite also occurs in the granodiorite, in weak stockwork zones or widespread quartz veins.

Dikes are common in the area, cutting all the above-mentioned rocks. Quartz monzonite, dacite, feldspar-hornblende-quartz porphyry, andesite, and rarely rhyolite compositions are present; however, none show mineralization.

No significant hydrothermal alteration is reported in the stocks or the older rocks.

Work History

In 1979, Utah Mines Ltd. spent four days sampling and mapping the roads on the south side of Hoodoo Creek on BZT 1 and parts of BZT 2 and 4.

In 2021, Goldplay Mining Inc. conducted prospecting and rock and soil geochemical in the area as the Big Frank Property.
