Author Description

Contains data from a geochemical survey conducted in the vicinity of the Mount Milligan, British Columbia, porphyry copper-gold deposit. The survey was undertaken to provide critical data for the design and interpretation of regional till surveys for porphyry copper-gold exploration. The investigators collected 121 till samples from 108 pits in a 150-square-kilometre area and analyzed them by instrumental neutron activation analysis or inductively coupled plasma emission spectroscopy. This survey report reviews the regional and surficial geology of the Mount Milligan study area, describes sample preparation and analysis methods, and presents results in the form of data tables, element distribution statistics by rock type, and maps of element distributions.
