Regional Highlights
The tabular component of the Connors uranium deposit has few Tertiary counterparts outside of North Dakota. The Colorado Plateau's Jurassic deposits may be the closest known analogues. Separately, the more convoluted, sandstone-hosted, roll-front uranium mineralization at Connors is geologically similar to two operating and six developing sandstone ISR projects located in South Dakota, Wyoming, Nebraska, and Colorado. The eight existing sandstone ISR projects have reserves and resources exceeding 103 million lbs U3O8. The largest is in excess of 40 million lbs U3O8. Most of these regional ISR deposits occur in Cretaceous, Paleocene, Eocene, or basal Oligocene sandstones. A single lignite-carbonaceous mudstone-sandstone unit of the Paleocene Sentinel Butte Formation is host to the Connors uranium deposit. Connors may increase internally and along strike. The northwest linear geometry of the Connors deposit is geologically anomalous when compared to the other regional Cretaceous, Paleocene, or Eocene uranium deposits. District-scale, northwest-striking, vertical fractures may be responsible for this anomalous geometry. If true, deeper Tertiary sandstone-mudstone-lignite horizons at Connors may contain additional uranium fixed by leaking hydrocarbon reductants moving upwards along the same fractures.
Project Location
The Connors uranium project is located in the Great Plains of southwestern North Dakota.
Project Geology
Geologic hosts are Paleocene lignite-carbonaceous mudstones and an overlying Paleocene sandstone of the Fort Union Formation. The known uranium mineralization is delineated by 250 historic drill holes. Two project scenarios are under consideration: open pit and ISR. Prospect Uranium tentatively estimates open-pit recovery could be 7.5 million pounds U3O8 from lignites, carbonaceous mudstones, and sandstone. Uranium mineralization is recognized with roll-front characteristics in a total of 21 drill holes within two statute, square-mile sections at Connors. Further development drilling of this ISR-capable configuration will undoubtedly be necessary before a sandstone roll-front ISR resource can be estimated. Tabular lignite and carbonaceous mudstone-hosted uranium mineralization is the majority of Prospect Uranium's in-house estimate (above).
