There is a good potential for discovering new metallic mines on Vancouver Island because much of the geology that has formed through the evolution of island arc-related rock suites is a favourable host for a range of mineral deposit types including porphyry Cu-Mo, volcanic massive sulphides and skarn mineralization. In addition to past and present producing mines such as Island Copper and Myra Falls, numerous mineral occurrences have been found and are still being developed.
Vancouver Island is also ideal for testing new geochemical exploration methods because it not only has varied geology, numerous mineral occurrences and different styles of metallic mineralization, but has also contrasting local climates, different surficial environments and physiographies. These features were incentives for the staff of the applied geochemical unit in the British Columbia Geological Survey to carry out a number of orientation studies in 1987 and 1988 with the aim of improving drainage geochemical survey techniques on Vancouver Island. Results of the studies were fully documented but were never reported at that time. Geofile 2008-8 contains full details of these geochemical studies.
