Standard Uranium announced on January 16 2025 the acquisition of the Umbra and Sable uranium projects in the prolific eastern Athabasca Basin, covering 3,680 and 1,590 hectares, respectively. The projects were acquired via low-cost staking and are now available for joint venture option agreements.
Overview of the eastern Athabasca Basin region highlighting Standard Uranium’s
newly acquired Umbra and Sable projects. Ground gravity surveys were completed
on the Rocas project and central Atlantic project claims.
Additionally, the Company is pleased to announce the completion of high-resolution ground gravity surveys on the Atlantic and Rocas projects. Designed to identify zones of possible hydrothermal alteration, these surveys upgrade existing drill targets and provide additional vectors for shallow uranium discovery in the eastern Athabasca Basin region.
Highlights
- Expanded Uranium Portfolio: Addition of the Umbra and Sable Projects – targeting high-grade* uranium mineralization and increasing exposure to the eastern Athabasca uranium district, providing additional joint venture and land deal opportunities.
- Umbra Project: Uranium targets along the confluence of electromagnetic (“EM”) conductors, interpreted graphitic/pelitic basement lithologies, and a resistivity low bullseye due west of the McArthur River mine.
- Sable Project: Targets across two distinct conductive zones with potential to host high-grade unconformity-related uranium mineralization
- .High-Resolution Ground Gravity: Two surveys completed, upgrading high-priority drill targets along conductive structural corridors on the Atlantic and Rocas projects.
The Umbra project comprises two mineral claims totalling 3,679 hectares, located 19 km WNW of the McArthur River Mine. The project area is 4 km NW along trend from West McArthur mineralized drill holes WMA-010 and WMA-004 which host up to 0.29% U3O8 (SMDI# 3553, 3551). On the eastern claim, Umbra covers the confluence of a strong EM conductor and interpreted graphitic/pelitic basement lithologies derived from the 2006 FALCON magnetic/gravity surveys, as well crosscutting E-W regional faulting.
Additionally, resistivity depth slices derived from the 2007 AMT survey identified a low resistivity hotspot which corresponds to a distinct flexure in the EM conductor on the eastern claim. The western claim hosts NE-trending magnetic lows coinciding with regional faulting – indicative of additional undefined conductive trends that warrant further geophysical investigation.
The Sable project is comprised of a single mineral claim totalling 1,590 hectares, located 35 km NW of the Cigar Lake uranium mine and approximately 42 km SW of the Hurricane uranium deposit. Sable covers two NE-SW trending magnetic lows, interpreted to represent prospective metasediments within folded granitic rocks. The inferred conductors extend over a strike length of more than 3 kilometres and remain untested by drilling.
The Company concludes that the new property acquisitions are prospective for discovery of high-grade unconformity-related uranium mineralization, typical of the eastern Athabasca Basin. Both the Umbra and Sable projects are relatively underexplored and would benefit from the completion of modern geophysical surveying and 3D inversions of historical data sets. The Umbra and Sable projects are available for joint venture and earn-in option opportunities.
Ground Gravity Surveys
MWH Geo-Surveys (Canada) Ltd. was contracted to complete high-resolution ground gravity survey grids along known conductive exploration trends on the Rocas projects and the central claims of the Atlantic project. Both surveys have been completed on time and data is currently in the inversion and modeling process which will provide additional vectoring layers for future drill programs. The surveys are designed to aid in the identification of potential zones of hydrothermal alteration of host rocks associated with uranium mineralization events. The gravity grids across the conductive structural corridors will upgrade drill targets for future exploration programs.
Standard Uranium at VRIC 2025
The Company will be attending and exhibiting at the Vancouver Resource Investment Conference on January 19th and 20th in Vancouver, BC. The conference is located at the Vancouver Convention Centre West and the Standard Uranium team was present.
