(photo courtesy of Vermillion Gold LLC) New semi-quantitative XRF spot gold concentrations (ppm) in drill core from a granite- greenstone terrane near International Falls . The XRF analyses were done in 2010 by MnDNR. This is an example of the drill core accessible to the public as part of the Drill Core Library's more than 3 million feet of archived materials. This specific section of core was submitted more than 20 years ago, unsplit by an exploration company that was focused on a different interval of bedrock.
