Noble Plains Uranium signs letter of intent with Ur-Energy for Shirley Central processing

Vancouver, British Columbia--(Newsfile Corp. - April 15, 2026) - Noble Plains Uranium Corp. (TSXV: NOBL) (OTCQB: NBLXF) (FSE: INE0) (" Noble Plains " or the " Company ") a U.S. focused uranium exploration and development company, is pleased to announce that it has entered into a non-binding Letter of Intent (" LOI ") with Ur-Energy Inc. (TSX: URE) (NYSE: URG) (" Ur-Energy ") outlining a framework for potential future processing of uranium-bearing solutions from Noble Plains' Shirley Central Project in Wyoming. The LOI reflects the parties' mutual interest in evaluating a future definitive processing agreement whereby uranium production solutions from prospective in-situ recovery (" ISR ") mine units developed at Shirley Central could be processed at Ur-Energy's nearby Shirley Basin ISR production facility, which is advancing toward first production. "This LOI represents a meaningful step forward in our strategy to rapidly de-risk and advance Shirley Central.

We are in the process of having Geomorphic AI digitize and model the extensive historical dataset, with the objective of converting historical mineralization into compliant pounds as efficiently as possible," said Drew Zimmerman, CEO of Noble Plains Uranium. "Having Ur-Energy not only as a strategic neighbour, but also as a shareholder and now a potential processing partner, sends a strong signal to the market. It reinforces our view that Shirley Central is a compelling near-term development opportunity in Wyoming's ISR uranium sector." This announcement builds directly on Noble Plains' acquisition of a large historical dataset comprising 1,211 drill holes at Shirley Central from Ur-Energy, a transaction that resulted in Ur-Energy becoming a shareholder of Noble Plains and further aligned the interests of both companies in advancing the project.

"We know the Shirley Basin extremely well and are advancing our own project toward its first production milestone. Noble Plains controls ground directly adjacent to our operations, and we believe it makes sense to explore collaborative opportunities as their project advances," said Matt Gili, CEO of Ur-Energy. "This non-binding LOI reflects our openness to a potential working relationship with Noble Plains as it moves through resource confirmation and development planning, while maintaining flexibility as both companies continue to execute on their respective strategies." Positioned for a Structurally Strong U.S. Uranium Market The United States is entering a sustained nuclear energy renaissance, driven by bipartisan federal support for domestic fuel supply, life extensions and restarts of existing reactors, and accelerating demand from data centres, defence, and electrification.

Against this backdrop, uranium supply constraints, particularly in Western jurisdictions, are becoming increasingly acute, placing a premium on domestic projects located in established production districts. Wyoming sits at the centre of this strategic shift. It offers regulatory clarity, ISR permitting precedent, and existing infrastructure, conditions that materially compress development timelines for projects capable of advancing beyond exploration.

At Shirley Central, Noble Plains is executing a strategy designed specifically for this environment: A substantial historical drill dataset now being systematically digitised, reinterpreted, and modelled utilizing cutting edge AI technology; A clear and efficient pathway toward defining compliant uranium resources, with reduced geological risk; Immediate proximity to permitted ISR infrastructure and processing capacity, allowing for potential development to be expedited; and Direct strategic alignment with an established U.S. uranium producer and shareholder, incentivised to see the project advance. Taken together, these factors position Shirley Central not as a conventional exploration story, but as a conversion and acceleration opportunity, one capable of progressing from historical data to production-level evaluation on a materially shorter timeline than typical early-stage uranium assets. In a market increasingly focused on speed, jurisdictional security, and execution, Noble Plains believes Shirley Central offers rare leverage to the strengthening U.S. uranium cycle.
