Noble Plains to digitize past Shirley Central data

Executive Summary

• Noble Plains Uranium Corp. has engaged Geomorphic AI to digitize and interpret 1,211 historical drill holes from its Shirley Central project in Wyoming, aiming to accelerate the path toward resource definition and confirmation drilling.
• The company completed a Phase 1 pilot successfully extracting gamma-ray traces, calibrating depth, and converting readings into estimated eU3O8 grades, and has now initiated full-scale production digitization of the remaining ~1,200 drill holes.
• The project is strategically located adjacent to Ur-Energy’s Shirley basin ISR project and bordered by Uranium Energy Corp., positioning Noble Plains between two major U.S. uranium developers.

Key Details

• Engagement Scope: Digitization and interpretation of 1,211 historical drill holes containing gamma-ray logs from the 1950s-1970s.
• Technology Partner: Geomorphic AI, utilizing purpose-built AI and computer vision workflows to transform legacy drill logs into high-quality, usable data.
• Phase 1 Pilot Results:
  • Accurately extracted gamma-ray traces across multiple historical log formats.
  • Calibrated depth and converted CPS readings into estimated eU3O8 grades.
  • Generated per-hole digital outputs with robust quality control metrics.
  • Built an integrated visualization platform incorporating maps and 3-D modeling.
• Current Status: Full-scale production digitization initiated for the remaining approximately 1,200 drill holes.
• Expected Deliverables:
  • High-resolution downhole gamma profiles at approximately 0.5-foot intervals.
  • Interpreted mineralized intervals with thickness, grade, and grade-thickness (GT) metrics.
  • Standardized outputs compatible with industry geological software (including LAS format).
  • Quality-controlled datasets with confidence scoring and QA overlays.
  • Fully integrated, interactive platform with drill hole summaries, mapping, and 3-D visualization.
• Strategic Outcome: The program will culminate in a summary report with composite statistics to prioritize follow-up drill targets for a confirmation drill program.
• Project Location & Context: Shirley Central consists of 30 unpatented mineral claims covering 665 acres in Wyoming's Shirley basin. It is adjacent to Ur-Energy’s project (which hosts a NI 43-101 compliant resource of 8,816,000 lb U3O8 at 0.23%) and bordered by Uranium Energy Corp.
