Noble Plains gets Duck Creek permit, begins drilling

Executive Summary

• Noble Plains Uranium Corp. has received the permit to proceed with a 37,400-foot drill campaign at its Duck Creek uranium project in Wyoming’s Powder River basin, with drilling now underway.
• The program is a strategic milestone aimed at building a NI 43-101 compliant uranium resource by spring 2026, focusing on ISR-amenable projects in a premier uranium district.
• The drill design has been optimized to approximately 175 holes (down from 198) to prioritize testing the deeper Fort Union formation while confirming and expanding known mineralization in the shallower Wasatch formation.

Key Details

• Drill Campaign Scope: Permit received for up to 37,400 feet of drilling; crews are mobilized and drilling is currently underway.
• Hole Count Optimization: Original plan of 198 holes refined to approximately 175 holes to reallocate footage toward deeper targets without reducing total footage.
• Program Objectives & Breakdown:
  • 16 Confirmation Holes: To validate 1,317 historic intercepts and underpin a potential future compliant resource.
  • Up to 140 Stepout and Expansion Holes: To increase the mineralized footprint and target higher-grade areas within the shallower Wasatch formation.
  • Up to 10 Deep Holes: To test the Fort Union formation at depths up to 1,200 feet (first drill holes on the project for this formation).
• Geological Context: Duck Creek is located in the Powder River basin, surrounded by deposits operated by Cameco Corp., Uranium Energy Corp., and American Uranium Ltd. The area hosts over 56 million pounds of uranium resources, primarily in the Fort Union formation, which is currently untested at Duck Creek.
• Data Collection Method: Downhole gamma-log probing is used immediately after drilling to provide daily results for rapid analysis and optimization of drill hole locations.
• Reporting Schedule: Results will be released in batches throughout the program.
• Target Date: Company aims to deliver a uranium resource prepared in accordance with National Instrument 43-101 standards by the spring of 2026.

Notable Quotes

• Drew Zimmerman, CEO: "This is another critical step in Noble Plains' mission to build an inventory of pounds in the ground... The drilling under way at Duck Creek is a high-impact program to confirm and expand known historical uranium mineralization as well as open new potential horizons at depth."
• Paul Cowley, COO: "From a geological standpoint, this program represents two distinct value streams... Success in discovering uranium mineralization at depth could open an entirely new growth horizon for Duck Creek that could align it with the resource scale of neighbouring projects."
