Noble Plains Uranium Engages Geomorphic AI to Digitize Historic

Shirley Central Drill Data, Advancing Toward Resource Definition

March 30, 2025 – Vancouver, British Columbia – Noble Plains Uranium Corp. (TSX-V: NOBL, OTCQB: NBLXF,

FSE: INE0) (“ Noble Plains ” or the “ Company”) a U.S. focused uranium exploration and development

company, is pleased to announce it has engaged Geomorphic AI to digitize and interpret the recently

acquired historical drill database of 1,211 historical drillholes on its Shirley Central Project in Wyoming’s

prolific Shirley Basin.

“The engagement of Geomorphic AI represents a step -change in how we are advancing Shirley Central,

leveraging purpose -built technology to rapidly convert a large historical dataset into a modern, high -

resolution geological model. This approach compresses timelines, reduces uncertainty, and accelerates

our path toward confirmation drilling and a compliant resource, while directly executing on our strategy

of unlocki ng value from high -quality brownfield assets through disciplined, data -driven advancement,”

stated Drew Zimmerman, CEO of Noble Plains Uranium. “With Shirley Central advancing toward drill-ready

targets and Duck Creek progressing toward our first compliant resource, we are building meaningful

momentum across our Wyoming portfolio as the fundamentals of U.S. uranium continue to strengthen.”

Jeff Phillips, Geomorphic AI’s VP of Business Development stated,“We’re excited to support Noble Plains

in unlocking the value of this extensive historical dataset. By applying our purpose -built AI and computer

vision workflows, we’re able to transform legacy drill logs into high-quality, usable data that can accelerate

geological interpretation and decision-making.”

Technology-Driven Strategy to Unlock Brownfield Value

The application of advanced digitization and artificial intelligence is a pillar of Noble Plains’ strategy to

unlock value from underutilized historical datasets. By integrating modern computational tools with legacy

exploration data, the Company is able t o materially enhance both the speed and quality of geological

interpretation.

At Shirley Central, Noble Plains is deploying purpose-built AI and computer vision systems to systematically

extract, standardize, and analy ze large volumes of historical drill data , with the strong belief that the

integration of AI -driven workflows represents a structural advantage in advancing brownfield uranium

assets, particularly where extensive historical work exists but are not being fully utilized.

As the Company continues to build its project portfolio, it intends to systematically apply these

technologies across its assets, establishing a scalable and repeatable process for converting historical data

into compliant resources. This technology-enabled approach is designed to improve capital efficiency and

enhance the probability of exploration success.

Rapid Advancement from Historical Data to Drill-Ready Targets

As previously announced, Noble Plains acquired a database comprising 1,211 historical gamma -ray logs

from uranium exploration conducted between the 1950s and 1970s. These logs, historically stored as

scanned images, contain extensive subsurface information but have not been usable in modern resource

estimation workflows.

Through its engagement with Geomorphic AI, Noble Plains is now converting this dataset into a digital

format using a purpose-built computer vision pipeline calibrated specifically for legacy uranium logs.

A Phase 1 pilot program has already been completed, successfully demonstrating the ability to:

• Accurately extract gamma-ray traces across multiple historical log formats

• Calibrate depth and convert CPS readings into estimated eU₃O₈ grades

• Generate per-hole digital outputs with robust quality control metrics

• Build an integrated visualization platform incorporating maps and 3D modelling

Following this successful pilot, Noble Plains has initiated full-scale production digitization of the remaining

~1,200 drill holes.

Delivering a Modern Exploration Dataset

Upon completion, the Company expects to receive a comprehensive and fully digitized dataset including:

• High-resolution downhole gamma profiles (~0.5 ft 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

• A fully integrated, interactive platform with drillhole summaries, mapping, and 3D visualization

Importantly, the program will culminate in a summary report with composite statistics the company will

utilize to prioritize follow-up drill targets for a confirmation drill program on the project.

Shirley Central’s is a Strategic Location for Future ISR Development

Shirley Central consists of 30 unpatented mineral claims covering 665 acres adjacent to the boundary of

Ur-Energy’s Shirley Basin ISR Project, which currently hosts a NI 43 -101 compliant Measured & Indicated

resource of 8.816 million lb U₃O₈ at 0.23%¹ and is preparing to start production with header house 1 -1

ready for injection and recovery pending final approval².

The Project is also bordered by Uranium Energy Corp. (UEC), placing Noble Plains directly between two of

the most active U.S. uranium developers.

About Geomorphic AI

Geomorphic AI is an AI -driven minerals prospect generator with a proprietary geoscience platform. It

deploys a purpose -built team of specialized AI agents for mineral exploratio n covering geology,

geochemistry, permit screening, data capture, and report writing. These agents collaborate like a seamless

digital exploration team. An orchestration engine autonomously evaluates targets via a structured

workflow (permits, environment, geochemistry, geology) with quality gates at every step. A persistent

evidence store captures every finding —drill intercepts, geochemical anomalies, permit checks —with

source, confidence, and coordinates. Geomorphic also builds custom tools for clients, such as log

digitization, 3D modeling, data room analysis, and report validation, with each engagement strengthening

the platform.
