This new work consists of laboratory analysis of 65 drill core samples (including standards) by Activation Laboratories Ltd. of Ancaster, Ontario. The samples were selected from 5 drill cores that had been drilled during the 1960’s through the 1980's, primarily by exploration companies searching for base metals and gold. Drill core and related exploration data are currently available at the Minnesota Department of Natural Resources Drill Core Library in Hibbing, Minnesota.
Sampling was guided by re-logging of the core and also by the use of a hand-held X-Ray Fluorescence (XRF) analyzer instrument. Files contain these new sample assays including standards and duplicates, XRF data, standards information, rare-earth element plots, and core locations. The chemistry from the XRF analyses is semi-quantitative by nature, and should NEVER be mixed with laboratory analyses and assays.
