At last November’s Yellowknife Geoscience Forum, it was hard not to notice a pattern emerging in presentations from precious and base metal explorers. Whether it was Osisko Metals exploring the Pine Point property that hosted a lead-zinc mine from 1964 to 1987, or Gold Terra Resource Corp. (formerly TerraX Minerals) working close to where more than 14 million gold ounces were mined at Con and Giant, companies touted their ability to analyze veritable treasure troves of physical data (in the form of core samples) stored on or near their properties.
