The Anna Lake Uranium-Molybdenum-Rhenium Deposit is located within the prolific Central Mineral Belt of Labrador, Canada, approximately 150 kilometers north-northeast of Happy Valley-Goose Bay and 35 kilometers southwest of the coastal community of Postville. The Deposit is hosted within the 5.75 square kilometre Anna Lake property.
The Central Mineral Belt is a northeast trending, one to two kilometre-wide Kanairiktok Shear Zone occurring at the intersection of the Nain and Makkovik geologic provinces. The Nain Province is comprised of tonalitic to granodioritic gneiss and variably deformed granodioritic intrusive bodies with subordinate mafic volcanic rocks of Archean age. The Makkovik Province consists of gneisses, granodioritic to granitic intrusive bodies, mafic to felsic volcanic and volcaniclastic rocks, and metamorphic equivalents varying in age from Archean to Paleoproterozoic.
The Anna Lake property claims are a part of the Makkovik Province within arcuate, en echelon, moderate angle reverse and/or thrust faults and nappes.
The oldest rocks underlying the Anna Lake property are grey-brown biotite schists, metasiltstone, arenite, and psammite, with lesser metavolcanic rocks belonging to the Post Hill Sedimentary Group. These rocks are in contact with an extensive pale-coloured, strongly-foliated, magnetite-rich, hornblende-biotite, granitic to granodioritic stock to the east, and a pink-coloured, generally weakly-foliated, magnetite-poor, hornblende-biotite, granitic to granodioritic stock to the west.
The Property also hosts small bodies of amphibolite, found within the metasedimentary rocks and the magnetite-rich granodiorite, as well as a series of northeast trending mafic dikes.
Uranium mineralization at the Anna Lake Deposit consists mainly of uraninite (UO2) and is hosted primarily within garnetiferous biotite schist belonging to the Post Hill Group of rocks. Sulphide content within portions of the biotite schist consists of up to 5% pyrrhotite, along with lesser amounts of molybdenum, rhenium, pyrite and chalcopyrite. Uranium mineralization within lithologies of the Post Hill Group are thought to be epigenetic and structurally-controlled, formed by the precipitation of uranium from solutions moving through the pre-existing rock or previously-deposited sediment.
