Dec 06, 2022 (Sheree Hinz) - Mineralization occurs within a white pegmatite dike in the eastern part of the Denna Lake Structural Complex. These dikes are composed mainly of plagioclase feldspar, white potassium feldspar and quartz with less than 5% mafic minerals (either biotite or diopside). They are roughly monzonites to syenites in composition.
Dec 06, 2022 (Sheree Hinz) - The dikes are rich in zirconium (660 ppm Zr), and adjacent clastic metasedimentary rocks commonly have high niobium, yttrium and zirconium contents compared to other clastic metasedimentary rocks from the Denna Lake Structural Complex.
