Jan 16, 2017 (A Wilson) - The main, or south showings located on lots 14 and 15 concession 7 lie within flat lying pegmatite dikes which strike north and dip flatly east. The dikes intrude paragneisses that are well banded amphibolite-biotite gneiss. The uranium-bearing pegmatites range from 6.1 to 12.2 m thick and are composed of pink feldspar crystals with graphic intergrouwths of quartz.
