The Superstition zone is one of three mineralized zones on the Silver Hope property that are southerly and along strike with the Equity Silver deposit and along what is called the Main Horizon. From north to south these are the Hope, Superstition and Gaul zones all of which occur in the Goosly volcanic rocks which are correlative with Cretaceous Skeena or Kasalka groups. See Gaul for details of the geological setting of the mineralized zones.
A stock of the Eocene Goosly Plutonic Suite occurs to the immediate east and consists of monzodiorite to gabbro.
In 1982, Equity’s mapping discovered a weakly mineralized outcrop in Superstition Creek centred approximately 500 metres south of the Hope Zone. A chip sample of an exposure of tan dust tuff with pyrite and tetrahedrite bearing fractures returned 0.22 per cent copper, 18 grams per tonne silver, 0.22 gram per tonne gold, 1.79 per cent arsenic, 0.011 per cent lead and 0.039 per cent zinc (Assessment Report 15710). By 1986, surface work and drilling delineated a zone trending 020 degrees, dipping westerly at 45 to 70 degrees and averaging 20 metres wide and 500 metres long. Mineralization was described as veinlets of chalcopyrite, sphalerite, arsenopyrite and tetrahedrite cutting variably sericitized and silicified Unit 2 dust tuffs. Drilling in 2011 showed the tuffaceous host rocks contain numerous bleached, brecciated, silicified and sulphide-rich zones. Pyrite is ubiquitous and it along with arsenopyrite, chalcopyrite, sphalerite and minor galena and molybdenite occur in fractures and tension gashes in the breccias. Starting at a downhole depth of 204 metres this mineralized zone yielded a 76 metre interval grading 0.43 gram per tonne gold, 29.37 grams per tonne silver and 0.19 per cent copper (Assessment Report 32622). This intersection also contains among the highest gold values of the 2010 and 2011 drilling programs with five samples assaying greater than 1 gram per tonne gold and one sample yielded 9.4 grams per tonne gold (Assessment Report 30988 and 32622).
