Purpose Extracted from Report 314:
PURPOSE A statewide reconnaissance-scale survey using 57 available overburden samples is being performed to search for kimberlite indicator minerals. The long range objective is to identify kimberlite bedrock sources to evaluate for diamond resources. The glaciofluvial samples are being analyzed by a contract laboratory. Three additional samples, spiked duplicates, were submitted for quality control. By using overburden samples available in the Drill Core Library or at the Minnesota Geological Survey, the funding could be applied fully to the sample processing and analysis, rather than to collecting.
