Over the past three summers, the detailed volcanology, hydrothermal alteration, and VHMS mineral potential have been investigated in the Five Mile Lake, Quartz Hill, Eagles Nest, Skeleton Lake, Needleboy Lake, and Six Mile Lake areas.en-USNeedleboy LakeSix Mile LakeGeological MappingVolcanic-hosted massive sulfide (VHMS) depositsHydrothermal alterationNatural Resources Research InstituteUniversity of Minnesota DuluthTechnical Report
