overview |

The B-Zone Uranium (± Vanadium-Silver-Copper) Deposit is located 135 kilometers north of Happy Valley-Goose Bay in Labrador, Canada, within the Central Mineral Belt, a prolific uranium district extending over 160 kilometres from the Labrador coast to the B-Zone / Moran Lake area. The Deposit is 3.75 kilometres northeast of the Labrador Uranium Inc Moran Lake C Zone Deposit and is hosted within the 1.5 square-kilometre B-Zone property.

Regional Geology

Central Mineral Belt

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 gneissic rocks, granodioritic to granitic intrusive bodies, mafic to felsic volcanic and volcaniclastic rocks, and metamorphic equivalents varying in age from Archean to Paleoproterozoic. 

The early-to-mid Proterozoic Moran Lake and Bruce River groups are the two volcano-sedimentary sequences important to uranium mineralization in the area. The B-Zone property is located within the Heggart Lake Formation of the 1.6 Ga Bruce River Group. 

Property Geology

Heggart Lake Formation

The B-Zone Deposit is underlain by the Heggart Lake Formation, a massive sandstone with interbedded conglomerate. Locally, it is variably-altered, strongly-silicified, and hematized to a maroon-red colour. Heggart Lake sandstones are cut by a number of north-striking, easterly-dipping, grey to green diabase dikes, which are spatially associated with (and probably temporally equivalent to) the Henri Lake gabbro that intrudes the Heggart Lake Formation and outcrops to the west of B-Zone mineralization.

Deposit Model

Sediment Hosted Uranium

At the B-Zone Deposit, epigenetic uranium mineralization occurs in the sedimentary rocks of the Heggart Lake Formation, notably in fractures filled by chlorite and quartz ± carbonate veining and/or minor breccia. A suite of altered intrusive rocks, typically mafic and dike-like, also host uranium and vanadium mineralization, especially near their contacts. 

Preliminary studies show that vanadium is correlated with copper mineralization, with up to 0.53% V2O5. Most samples contain minor quantities of sulphide, but there are several samples that exhibit 1% to 2% pyrite and chalcopyrite. Pyrite, chalcopyrite, bornite and chalcocite mineralization are spatially associated with the chlorite-magnetite alteration. Limited petrographic examination suggests that the main uranium mineral present at the B-Zone is brannerite (UTi2O).
