Key Terms

high-pressure slurry ablation, gamma probe, u.s. nuclear regulatory commission, service providers license, +2 more

6 terms

high-pressure slurry ablation technical

"DISA will deploy its patented High-Pressure Slurry Ablation ("HPSA™") system"

A high-pressure slurry ablation is a medical procedure that removes unwanted tissue by directing a fast-flowing mix of fluid and tiny particles at the target, similar to using a power washer to strip away material from a surface. For investors, it matters because this technique can offer a less invasive alternative to surgery, potentially shortening recovery, lowering costs, and creating demand for specialized devices and regulatory approvals that affect company value.

gamma probe technical

"Launch a characterisation programme with a combination of assay and gamma probe"

A gamma probe is a handheld medical device that detects tiny amounts of radioactive material inside the body, helping surgeons locate tumors, lymph nodes or other targeted tissue during procedures. For investors, its importance lies in enabling faster, more precise surgeries and potentially improving patient outcomes, which can drive hospital adoption, device sales, reimbursement decisions and recurring revenue for companies that make or supply the probes and their radioactive tracers.

u.s. nuclear regulatory commission regulatory

"first company to receive a Service Providers License from the U.S. Nuclear Regulatory Commission"

A federal agency that licenses, inspects and enforces safety rules for civilian nuclear power plants and other uses of radioactive materials in the United States. Think of it as the official safety inspector and rulemaker for the nuclear industry—its approvals, inspections, fines and rule changes can speed up or delay projects, change operating costs, and alter legal and financial risk, so its actions directly affect companies’ prospects and investor value.

service providers license regulatory

"first company to receive a Service Providers License from the U.S. Nuclear Regulatory Commission"

A service providers license is a regulatory permit that authorizes a company to offer specific services—such as financial advice, payment processing, healthcare services, or telecommunications—within a jurisdiction. Like a driver's license for a business, it shows regulators have approved the firm's qualifications, controls, and compliance procedures; for investors it signals whether a company is legally allowed to earn revenue from those services and highlights potential regulatory or operational risks.

radium-226 medical

"with comparable reductions in radium-226."

A radioactive isotope of the element radium, radium-226 emits radiation as it decays and has a long half-life, meaning it remains active for many years. It matters to investors because its use, handling, transport, storage, and cleanup are tightly regulated and can create business opportunities or long-term liabilities—similar to owning a property with a stubborn, slow-moving hazard that affects costs, permits, and public safety obligations.

u3o8 technical

"historical production of approximately 5.3Mlbs U3O8 over two discrete"

U3O8 is the chemical name for a stable form of uranium oxide commonly called “yellowcake,” the concentrated powder produced after uranium ore is processed. Investors track U3O8 because it represents the raw material that is turned into nuclear fuel; its supply, demand and price act like a commodity indicator that can move the value of mining companies, utilities and firms tied to the nuclear fuel chain. Think of it as the crude oil equivalent for nuclear power — a basic feedstock whose availability and cost affect an entire industry.

Winnipeg, Manitoba--(Newsfile Corp. - July 7, 2026) - Frontier Nuclear and Minerals Inc. (NASDAQ: FNUC) ("Frontier"), a nuclear fuel cycle company, announces that it has signed an agreement with DISA Technologies Inc. ("DISA") to characterize and remediate legacy uranium mine waste dumps and to recover saleable uranium at Frontier's 100% owned Maybell uranium project (the "Maybell Project") in Colorado.

Environmental remediation and uranium recovery will occur simultaneously
at the former Maybell uranium mine

Highlights:

• DISA will deploy its patented High-Pressure Slurry Ablation ("HPSA™") system in modular mobile plants to recover saleable uranium and other critical mineral concentrates from waste dumps at the Maybell Project

• Frontier Nuclear will be paid a net revenue royalty based on a sliding scale royalty rate of between 2.5% to 4% based on uranium price and derived from the sale of uranium and other critical minerals extracted from the waste dumps at the Maybell Project

• DISA will operate the waste remediation program at the Maybell Project and pay all associated costs

• No capital or operating costs will be payable by Frontier

• A total of 17 separate prospective waste dumps have been identified through ground surveys at the Maybell Project to date, and others may be added over time

• HPSA™ is a patented, chemical-free, modular process that selectively separates uranium and other target minerals from waste material using high-velocity slurry collisions.¹

CEO Remarks

"We are pleased to have partnered with DISA to apply its breakthrough process to remediate abandoned uranium mine waste at our Maybell Project, and to recover valuable uranium and critical minerals, while addressing the environmental impacts of historical uranium mining," said Frank Wheatley, CEO of Frontier.

"With uranium demand at multi-decade highs and the U.S. Government actively prioritizing domestic critical mineral recovery, the timing could not be better to unlock the value contained in our Maybell Project's legacy waste dumps."

Next Steps:

DISA will:

• Launch a characterisation programme with a combination of assay and gamma probe to determine likely quantities of uranium and other recoverable minerals present in the waste dumps, expected to take approximately six months

• Apply for all requisite permits necessary to commence treatment of waste and recovery of payable concentrates using HPSA™ technology

• Pay Frontier a net revenue royalty on future sales of metals concentrates

Advantages of HPSA™:

• The HPSA™ process treats surface dumps of previously partially mined and aggregated material, and has been independently validated through a U.S. Environmental Protection Agency ("EPA") treatability study ("EPA Study") conducted at three Navajo abandoned uranium mine sites in 2022 and published in December 2023

• In September 2025, DISA became the first company to receive a Service Providers License from the U.S. Nuclear Regulatory Commission, providing a regulatory license for DISA to remediate legacy uranium mine waste. DISA can now recover valuable uranium and critical minerals, and more importantly, leave the environment significantly improved

• There is strong US Government support for domestic recovery of uranium and critical minerals from legacy mine waste. This activity is directly in line with the recent Secretarial Order No. 3436, which directs federal agencies to prioritize domestic recovery of critical and strategic minerals from mine waste

U.S. EPA Study

The EPA Study, carried out by Tetra Tech Inc. under EPA contract, found that the HPSA™ process reduced uranium concentrations in treated material by between 61% and 94% depending on waste characteristics, with comparable reductions in radium-226. A particularly significant finding: the process concentrates more than 90% of the uranium content into a fines fraction that represents just 17% of total processed mass — leaving the bulk of the treated material clean enough to remain on site and dramatically reducing the volume of material requiring regulated disposal. The EPA confirmed the HPSA™ process as a viable treatment technology for abandoned uranium mine waste on Navajo Nation lands and on other state and federal lands, a conclusion directly applicable to legacy mine waste sites such as the Maybell Project. The full study is publicly available on the EPA website.²

Maybell Uranium Project

The Maybell Project, 100% owned by Frontier, is located at the southern end of the Sand Wash Basin between the towns of Maybell and Lay in Moffat County, Colorado. It covers an area of approximately 9,497 acres and is comprised of 480 Federal mining claims (8,857 acres) and one State Exploration Lease (640 acres). The Maybell Project has witnessed historical production of approximately 5.3Mlbs U₃O₈ over two discrete historical mining periods. The location of the waste dumps on the Maybell Project are set out in Figure 1, attached as Schedule A.
