The former Standard mine is located 2.5 kilometres southeast of Burnell Lake and 3 kilometres northwest of Oliver, British Columbia.
Regionally, the area is principally underlain by medium grained intrusive rocks that form the Jurassic Oliver plutonic complex. To the south, the complex cuts Carboniferous to Permian Kobau Group metasedimentary rocks. On its northern margin, the intrusive mass is in contact with Eocene volcanics and sediments of Penticton Group.
In the Standard occurrence area, the Oliver plutonic complex is composed almost entirely of quartz monzonite. Three distinct phases are evident. A central core of massive, medium grained garnet-muscovite quartz monzonite is surrounded by biotite-hornblende quartz monzonite north of the core and porphyritic biotite quartz monzonite to the south. Hornblende diorite occurs in several small areas to the immediate north.
The Standard mine is hosted by the hornblende-bearing porphyritic quartz monzonite northern phase of the Oliver plutonic complex. Nearby, a swarm of fine to medium grained, quartz monzonite dikes cut this unit. The area has been extensively faulted and fractured. Regional hydrothermal alteration has resulted in epidote which occurs in seams up to 2.5 centimetres in width.
Mineralization ranges from 5 per cent in auriferous sections to less than 0.5 per cent in the barren south section. In decreasing order of abundance, coarse patches of pyrite, chalcopyrite, galena, sphalerite, tetrahedrite and specks of hessite comprise mineralogy.
Total recorded production from the former Standard mine included 2411 tonnes mined in 1961 by Norex Mines Ltd. and in 1962 by Continental Corporation Mines Ltd. Recovery included 165,343 grams of silver, 36,795 grams of gold, 3474 kilograms of lead and 2468 kilograms of zinc.
Note: there are specimens in the Sutton-Thompson Collection at the Pacific Museum of Earth (UBC); catalogue numbers 880, 3330 and 3704.
