Mar 23, 2020 (Therese Pettigrew) - Lambert Island, off Amethyst Harbour, is underlain by a diabase sill which presumably overlies Animikie sediments. Approximately $500 were expended in 1884 in testing a vein of rose-coloured quartz and fluorite between 18 inches and 3 feet wide which trends northwest across the island. A pit was sunk on the vein. It did not penetrate through the diabase sill, estimated to be 30 feet thick (Ingall, 1888).
