Noble Plains Uranium Receives Drill Permit FOR Rapid Advancement of Shirley Central Project
NOBLE PLAINS URANIUM RECEIVES DRILL PERMIT FOR RAPID ADVANCEMENT OF SHIRLEY CENTRAL
PROJECT
August 7, 2025 – Vancouver, British Columbia – Noble Plains Uranium Corp. (TSX-V: NOBL, OTCQB: NBLXF,
FSE: INE0) (“Noble Plains” or the “Company”) is pleased to announce that it has received a drill permit for
a 22-hole confirmation drill program at its Shirley Central Project in Wyoming’s Shirley Basin - just two
months after securing the option on the property. The rapid permitting reflects the Company’s focused
approach to advance high-potential brownfield uranium assets in premier U.S. jurisdictions.
The permitted drill program will test six target zones (shown below in figure 1) identified through historical
drill density and aerial mapping, with the goal of confirming historical mineralization and fast-tracking the
project toward an initial 43-101 resource estimate. Mobilization for drilling is expected in mid-September.
“This shows the execution of our strateg y, move quickly, focus ing on the premier basins, and advance
projects with a clear path to building uranium pounds in the ground,” said Drew Zimmerman, President of
Noble Plains Uranium. “The speed at which we’ve moved from acquisition to planned and permitted drilling
at Shirley Central shows our team’s ability to act decisively to build value for shareholders.”

In the Heart of a Growing Production Hub
The Shirley Central Project sits at the core of a resurging uranium district and is surrounded by two of the
most active U.S. developers : Ur-Energy Inc. and Uranium Energy Corp. (UEC) . Several of Noble Plains’
claims lie directly within Ur-Energy’s permit boundary, while others are encircled by UEC’s land package,
placing the Company in the middle of a rapidly advancing production corridor.
Ur-Energy’s adjacent Shirley Basin Project currently hosts a 43-101 compliant Measured and Indicated
resource of 8.816 million pounds U₃O₈ at an average grade of 0.23%¹ and is under construction²—further
validating the regional potential.
“This land was historically drilled with purpose , the high-density drilling was positioned between known
producing pits,” said Paul Cowley, CEO of Noble Plains. “That kind of geological footprint allows us to step
in with targeted confirmation drilling and accelerate the path toward a compliant resource. It’s an efficient
and technically sound approach to unlocking value.”
High-Confidence Targets from Historic Data
The Company’s 22-hole program will focus on six discrete high -density drill zones originally outlined by
legacy operators, including Kerr-McGee. These zones feature drill spacings as tight as 25m x 25m, a pattern
indicative of focused resource delineation efforts. This historical groundwork offers Noble Plains a cost -
effective, low risk starting point for modern resource definition.
Drilling will be carried out by a Wyoming -based contractor, with logistics and mobilization scheduled for
mid-September.
This program represents a key milestone in Noble Plains’ strategy to build out a pipeline of ISR-amenable
uranium projects in infrastructure-ready U.S. basins, backed by historical data and modern exploration.
Shirley Basin
The Shirley Basin has produced more than 52 million pounds of U₃O₈ at an average grade of 0.22%
between 1960 and 1992—over three times the current U.S. average. As part of Wyoming, the top uranium-
producing state in the U.S. and an NRC Agreement State, the Basin benefits from a streamlined permitting
environment and longstanding regulatory support for in-situ recovery (ISR) operations.
With ISR now the dominant mining method in Wyoming, Noble Plains’ newly optioned claims offer
exceptional leverage to modern, low-impact development methods. ISR provides lower capital intensity,
minimal surface disturbance, and no tailings, aligning with the Company’s commitment to environmentally
responsible exploration.
