The Lynne Deposit is a Volcanogenic Massive Sulfide Deposit in Oneida County in northern Wisconsin containing zinc, lead, silver, and small amounts of gold and copper. In 1990 and 1991, the Noranda Company drilled 133 exploration boreholes, and the core from some of these holes was donated to WGNHS and the Natural Resource Research Institute (NRRI) in Duluth, MN. In 2021, the NRRI donated core from seven holes to WGNHS. These cores were photographed, and detailed logs were created by Dr. Robert Lodge and students from the University of Wisconsin Eau Claire. Original documentation from the Noranda Company including logs, assays, cross sections, reports, and a site map are available at Oneida County’s website: https://www.co.oneida.wi.us/archive/mining/category1da1.html?linkcatid=9 [...]
