Project Highlights

15 kilometres of relatively untested ground on the Patterson Lake Corridor

Maiden Denison-operated reconnaissance drill program completed in 2018

Designed to generate targets for further exploration drilling in 2019 and beyond


Hook-Carter is located near the southwestern margin of the Athabasca Basin, in northern Saskatchewan approximately 25 kilometres east of Highway 955. The property is accessible year round by utilizing a combination of vehicular and helicopter and/or fixed wing aircraft. Hook-Carter is highlighted by 15 kilometres of strike potential along the Patterson Lake Corridor – host to the recently discovered Triple R deposit (Fission Uranium Corp.), Arrow deposit (NexGen Energy Ltd.), and Spitfire discovery (Purepoint Uranium Group Inc., Cameco Corp., and Orano Canada), which occur within 8 to 20 kilometres of Hook-Carter.


In November 2016, Denison acquired an immediate 80% ownership of the entire Hook-Carter property (“Hook-Carter”), from ALX, in exchange for the issuance of 7,500,000 common shares of Denison. Under the terms of the agreement, ALX will retain a 20% interest in Hook-Carter and Denison has agreed to fund ALX's share of the first $12,000,000 in expenditures. Denison will be the operator of the project and will retain full discretion as to the nature, extent, timing and scope of all work projects on Hook-Carter.

Under-Explored Potential

Hook-Carter features between 250 and 700 metres of Athabasca Group sandstone cover overlying the basement rocks that define the prospective geological trends or corridors. As a result, Hook-Carter offers both basement- and unconformity-hosted uranium deposit potential.

Hook-Carter is significantly under-explored compared with other properties along this trend with only eight historic drill holes, including only five holes over the 15 kilometres of Patterson Lake Corridor strike length. Three historic holes have been completed on the Derkson Corridor and no drilling has been carried out on the Carter Corridor. Results from historic holes (including sandstone alteration, geochemistry and basement geology and structure) suggest favorable environments for the presence of unconformity-related uranium deposits. All the holes drilled to date were designed to test the unconformity (seldom penetrating more than 100 metres into the basement) and therefore the basement is considered unexplored. The five holes on the Patterson Lake Corridor are between 1.5 and 4.3 kilometres apart and considering the corridor is comprised of multiple conductors, significant space and potential exists for sizeable deposits.

Previous exploration work has been dominated by geophysical surveys dating back to 1997. Airborne surveying has included property-wide electromagnetics (including a VTEM™ survey on the Patterson Lake Corridor), a property-wide medium-resolution magnetic survey and limited Falcon® Airborne Gravity Gradiometry and HeliSAM TEM surveying. These data sets provide an excellent repository for the interpretation of basement geology and area selection for further targeting. Ground geophysical surveying has included property-wide electromagnetic surveys on a reconnaissance spacing. The airborne and ground electromagnetic survey results indicate the prospective corridors on Hook-Carter are comprised of multiple conductors suggesting numerous graphitic target horizons are present. Surficial surveys completed include lake sediment sampling, radiometric sampling, and boulder sampling. Anomalies produced by boulder and lake geochemistry along the Patterson Lake corridor provide further encouragement for mineralization.
