Abstract
Biogeochemistry, like geophysics, is a useful tool for those who seek ore in areas where outcrops are few, vegetation heavy, or glacial drift widespread. Knowledge of the normal amounts of, as well as the ratios existing between, any elements in the selected organs of appropriate trees and lesser plants growing under the various geological and geographical conditions involved in a chosen area, makes it possible to discover biogeochemical anomalies should any be present. Experience in British Columbia suggests that in a search for copper or zinc, a study of the ratios existing between the amounts of these elements present in young twigs affords a simple and usually effective way of detecting anomalies. By using twigs, it is practical to carry on investigations during seasons when weather conditions make some types of prospecting impossible. Biogeochemistry is not a rival of geophysics, geology, or hard work as a means of finding ore. It is another tool which, if employed intelligently under appropriate but not necessarily ideal conditions and in conjunction with other suitable tools, can do much to assist in a search for hidden ore.
