The Most Prospective Exploration Project in the Basin

Hook Lake


About Hook Lake

Located within the Patterson Uranium District, the Hook Lake is a project owned jointly by Cameco Corporation (39.5%), Orano Canada Inc. (39.5%) (formerly known as Areva Canada Inc.)  and Purepoint (21%).

Operated by Purepoint since 2007, the project consists of nine claims totaling 28,598 hectares including the Spitfire high-grade discovery (53.3% U3O8 over 1.3 metres including a 10 metres interval of 10.3% U3O8).

The depth to the Athabasca unconformity is very shallow, ranging from zero to 350 metres. Three prospective structural “corridors” have been defined on the property, each corridor being comprised of multiple EM conductors that have been confirmed by drilling to result from prospective graphitic shear zones

The Patterson Uranium District is a structural corridor situated on the SW edge of Saskatchewan’s Athabasca Basin, interpreted to extend at least 50km, and host to Fission Uranium’s Triple R deposit, NexGen’s Arrow deposit and Purepoint Uranium’s Spitfire discovery.

A 2019 airborne gravity survey funded by the Targeted Geoscience Initiative (TGI), a collaborative federal geoscience program, has provided results suggesting that uranium deposits may form proximal to gravity highs. Purepoint considers the gravity highs of the first vertical derivative (Boulanger, Kiss and Tschirhart, 2019) to be reflecting ultramafic intrusives within granodioritic gneisses. The density contrast of the two lithologies may be providing zones of weakness along their contacts where structural traps for uranium-rich fluids are being preferentially formed.
