NexGen Energy Ltd. (‘NexGen’) engages in uranium development and exploration.
NexGen is a British Columbia corporation focused on developing into production the 100% owned Rook I Project (the ‘Rook I Project’), located in the southwestern Athabasca Basin of Saskatchewan, Canada. The company discovers uranium deposits and is involved in the development of projects from discovery to production. NexGen also owns a portfolio of highly prospective uranium properties in the southwestern Athabasca Basin of Saskatchewan, Canada.
NexGen’s land package consists of the SW1, SW2, and SW3 properties. The Rook I Project is located within the broader Rook I property. The Rook I property consists of thirty-two (32) contiguous mineral claims totaling 35,065 hectares, and comprises a portion of SW2.
The company has further advanced critical path procurement activities for the Rook I Project, as well as the FEED and critical path detailed engineering.
Permitting, Regulatory, and Engagement
On February 12, 2024, NexGen received the results of the Canadian Nuclear Safety Commission (‘CNSC’) technical review of the company’s responses to Federal information requests received on the Draft Environmental Impact Statement (the Federal ‘EIS’) through the Federal Environmental Assessment (the Federal ‘EA’) review process. On May 21, 2024, the company submitted responses to the remaining information requests from the CNSC’s February 12, 2024, correspondence, along with a revised Federal EIS. The CNSC concluded its completeness check of NexGen’s May 21, 2024, submission on June 21, 2024.
On November 19, 2024, the CNSC confirmed the completion of the Federal technical review of NexGen’s May 21, 2024, submission, stating that the company’s responses to all information requests received through the Federal technical review process had been accepted, and that the information provided by the company fully addressed the regulatory requirements for the Federal EA.
On January 28, 2025, the CNSC announced its acceptance of the Federal Final EIS. The next and final step in the Federal approval process is scheduling a Commission hearing date for the Rook I Project, subject to which the CNSC will render an approval decision on the Rook I Project.
Exploration
On March 11, 2024, the company announced the discovery of new intense uranium mineralization on its 100% owned Rook I property, 3.5 kilometers (‘km’) east of the Arrow Deposit. The new mineralized occurrence in RK-24-183 is located on a previously untested conductor segment of Patterson Corridor East (‘PCE’). Localized uranium mineralization was intersected for 19.8 m between 347.7 and 367.5 m, with counts per second (cps) ranging from <500 to >61,000, as measured with a handheld RS-125 spectrometer.
On May 29, 2024, the company announced an additional discovery of mineralization in RK-24-193 at PCE over 67.5 m between 383.5 and 451.0 m. Additionally, assay results from RK-24-183 reflected two narrow, mineralized veins with best intervals of 10% U3O8 over 0.5 m at 348.0 m, and 6.23% U3O8 over 0.5 m at 356.5 m, respectively.
On August 8, 2024, NexGen announced the expansion of the mineralized zone at PCE to include a total of eight drill holes intersecting mineralization, four of which intersected off-scale (>61,000 cps) high-grade uranium mineralization, as measured with a handheld RS-125 spectrometer. These included RK-24-183, -197, -202, and -207. The high-intensity style mineralization is indicative of exceptional formation conditions similar to those found in the significant orebodies within the Athabasca Basin. The mineralized signature is expressed as analogous to other orebodies within the Athabasca Basin, with localized veins (up to off-scale >61,000 cps) within elevated radioactivity that extends over more than 100 m.
On November 12, 2024, NexGen completed the 2024 exploration program with over 34,000 m drilled and an expanded mineralized footprint. Included within the results was the best hole to date at PCE, RK-24-222, that intersected a 17.0 m wide interval with multiple high intensity (>61,000 cps) occurrences.
Subsequent to December 31, 2024
On January 30, 2025, NexGen announced the commencement of a 43,000 m exploration drill program to continue to test the extents and growth of mineralization discovered in early 2024 at PCE. This systematic program represents an increase of 9,000 m from the 2024 program and is expected to be one of the largest drill programs in the Athabasca Basin, Saskatchewan, in 2025.
The Rook I Project
On February 22, 2021, the company announced positive results from the Feasibility Study for the Rook I Project.
The Rook I Project is located in northwest Saskatchewan, approximately 40 km east of the Alberta–Saskatchewan border, 150 km north of the town of La Loche, and 640 km northwest of the city of Saskatoon. The Rook I Project can be accessed via all-weather gravel Highway 955, which travels north-south approximately 8 km west of the Arrow Deposit. From Highway 955, a 13 km long all-weather, single-lane road provides access to the western portion of the Rook I Project, including the Arrow Deposit area.
The Rook I Project is covered by boreal forest common to the Canadian Shield. Bedrock outcrops are very rare, but are known to exist in areas of the eastern half of the project area.
As of December 31, 2024, all 32 contiguous mineral claims comprising the Rook I property, a total of 35,065 ha, are in good standing with expiry dates between June 2040 and June 2043, and are all registered in the name of NexGen.
The Rook I Project is located on provincial Crown land; as the owner, the Province of Saskatchewan can grant surface rights under the authority of the Forest Resources Management Act and the Provincial Lands Act.
