WIUGC 2010 - Pegmatite and Leucogranite-Hosted U-Th Mineralization In northern Saskatchewan: Fraser Lakes Zones A and B

Pegmatite- and leucogranite-hosted uranium and thorium mineralization in northern Saskatchewan: Fraser Lakes Zones A and B Christine Austman, Kevin Ansdell, and Irvine Annesley

Outline ,[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],[object Object],“ The aim of this project is to determine whether these [granitic pegmatites and leucogranites] represent a distinct target for uranium exploration in Saskatchewan or if the mineralization is related somehow to unconformity-type uranium deposits. “
