District-scale radiometric anomalies discovered at PLN’s Skull Creek uranium project in Colorado

• PLN flags radiometric anomalies hinting at large scale uranium mineralisation at Skull Creek
• Project could benefit from US policy shift to secure domestic supply
• Company planning to zero in on drilling targets at the project

Special Report: Pioneer has found district scale radiometric anomalies during soil sampling at its Skull Creek uranium project in Colorado, USA.

The company has detected broad zones of new undiscovered and untested radiometrically anomalous basement across the length of the 17km long strike of the project, indicating the potential for large scale uranium mineralisation. 

While radiometrics are not a proxy for assays, they will help Pioneer Lithium (ASX:PLN) zero in on future drilling targets.

Skull Creek sits within the Colorado Plateau uranium province including the historic Uravan Belt, with a scale and stratigraphy consistent with deposits mined across that district. 

The main potential drilling target of Blue Mountain previously reported high-grade uranium rock chip results up to 1240ppm U3O8) from the Sego Sandstone. That’s now been underpinned by a new 1km long zone of anomalous radiometric readings.

Pioneer is strategically positioned to benefit from geopolitical and market tailwinds as US policy support sharpens for uranium producers, with Skull Creek emerging as a compelling asset in a tier-1 jurisdiction.

Exciting results

Pioneer CEO Michael Beven said the preliminary results interpreted from the radiometric recordings taken from the bottom of each sample location “are exciting.”

“They demonstrate large areas of elevated radioactivity across the full length of the prospect which were previously undetectable due to the presence of the soil cover,” he said. 

“The low-cost initial phase 1 orientation survey was successful in determining that the soil development at Skull Creek is poor and does not feature reliable substrate for consistent sampling across the greater extent of the project.”

With this determined Pioneer completed phase 2 of sampling by taking samples by digging through the soils and sampling from the very top of the weathered bedrock. 

“What we have identified now are broad coherent areas of radiometric anomalism never discovered or tested of a scale suitable to potentially host economic zones or uranium mineralisation,” Beven said. 

“These anomalous zones match the strike orientation of the target lithologies and extend for up to a kilometre in some instances”

While assays are pending from the soil sampling, applications for drill permitting are underway with the team poised to mobilise back to site for detailed geological mapping to close in further on potential drill targets.
