Noble Plains Uranium Corp. has reported preliminary results from an induced polarization geophysical survey at its flagship Duck Creek Property in Converse County, Wyoming, identifying a significant anomaly interpreted as a potential redox front in the underlying Fort Union Formation.

The survey, conducted by the University of Wyoming Near-Surface Geophysics Instrument Center, tested a single 1,600-metre east-west oriented line across the property. Preliminary results identified an anomaly extending approximately 380 metres along the line at a depth of roughly 200 metres within the Fort Union Formation.

The same survey line also independently detected shallower mineralization in the Wasatch Formation, validating the geophysical method against known geology. The Duck Creek Property hosts a maiden NI 43-101 mineral resource of 5.32 million pounds of Indicated U₃O₈ and 1.04 million pounds of Inferred U₃O₈ located entirely within the Wasatch Formation, following a 148-hole drill program completed earlier in 2026.

The Duck Creek project is situated between Cameco Corporation's Smith Ranch-Highland project and Uranium Energy Corp.'s Barge project in the Powder River Basin. While the property's existing resource sits in the shallower Wasatch Formation, the underlying Fort Union Formation hosts neighbouring deposits but has not been properly tested on Duck Creek.

“It is worth being clear about what our 6.36-million-pound resource at Duck Creek actually represents,” stated Drew Zimmerman, CEO of Noble Plains. “That resource sits on roughly 2.5 miles of a 5.25-mile trend, and every pound of it comes from the shallower of the two formations we consider prospective. Historical open pits further along that same trend tell us the mineralization does not stop where our resource stops. We now have our first target in the deeper Fort Union Formation, the horizon that holds most of the known uranium in this part of the Powder River Basin, including on the neighbouring projects held by Cameco and UEC. The question is how many more pounds are along the trend and in the formation below, and how efficiently we can define them.”

The University of Wyoming Near-Surface Geophysics Instrument Center is currently completing further data processing and inversion of the survey data. Noble Plains plans to evaluate running multiple east-west oriented induced polarization lines along the 5.25-mile property length to map and model the Fort Union redox front ahead of potential drill testing.
