The Corey Elgar showing is underlain by rock of the Jurassic Hazelton Group, including rocks of the Lower Jurassic Betty Creek and Middle Jurassic Salmon River formations.
Mineralization occurs as galena, sphalerite, pyrite and arsenopyrite in a quartz carbonate stockwork hosted by andesite tuff. Best values obtained were in float. The highest of these, VV-B-F-034 (Map 6 and 20), assayed 0.32 gram per tonne gold, 15.5 grams per tonne silver, 0.28 per cent zinc and 0.22 per cent arsenic (Assessment Report 23805).
The sample was taken by Kenrich Mining Corp in 1993 on their Corey property. See Cumberland (MINFILE 104B 011) for details of the Corey Property history.
