The silt plus clay-sized fraction of 117 basal till samples collected within the Redstone and Loomis Lake map areas (approximately 150 km west of William’s Lake) was analyzed for 37 elements by aqua regia digestion followed by inductively coupled plasma mass spectrometry (ICP-MS) and 35 elements by instrumental neutron activation analysis (INAA), while an additional 38 basal till samples were collected for analysis of heavy metal concentrates and gold grain counts.  The spatial distribution of samples elevated in Cu, Mo, Pb, Zn, Ag, Ni, Hg, As, Cr, Sb, and visible gold grains are the focus of this study.  Data presented here outline two new multi-element, multi-site till geochemical exploration targets.  Follow-up field work is required to assess the significance of these new exploration targets.

World fluorspar resources, market and deposit examples from British Columbia, Canada

Information Circular 2009-4

Key questions addressed in this paper are: “Will the demand for fluorspar outstrip supply in foreseeable future?” and “Will there be enough raw materials to cover projected demand?” The demand for fluorspar is linked to global economic cycles. This paper concentrates on the global availability of fluorspar from the perspective of geological and mineral engineering economics.  British Columbia has several fluorite-bearing deposits that are discussed in this paper.
