WINNIPEG, Manitoba, July 14, 2026 (GLOBE NEWSWIRE) -- Frontier Nuclear and Minerals Inc. (NASDAQ:FNUC) ("Frontier"), a nuclear fuel cycle company, announces the launch of its 2026 drill program at its 100% owned Pine Ridge uranium project ("Pine Ridge") in Wyoming’s Powder River Basin.

A 36,000 m Drill Program designed to generate

a maiden mineral resource estimate

Highlights

2026 drill program (the "Drill Program") at Pine Ridge is underway
Drill program will consist of approximately 120 holes totaling approximately 36,000 m
Drill Program will build on the successful 2025 drill program which:
- confirmed widespread uranium mineralization;
- demonstrated continuity of mineralization across multiple areas; and
- identified at least 25 mineralized roll fronts contained within multiple major sandstone packages.
Objective of the Drill Program is to define roll front deposits and target preparation of a maiden mineral resource estimate (the "MRE") by early 2027
Pine Ridge is a large-scale uranium exploration project located in Wyoming’s prolific Powder River Basin covering approximately 39,390 acres

CEO Commentary

"After a successful initial drill campaign during 2025, we have initiated an extensive 2026 drill program at Pine Ridge," said Frank Wheatley, CEO of Frontier. "The clear objective of this program is to complete sufficient drilling to prepare a maiden mineral resource estimate by early 2027."

"As the U.S. Government continues to prioritize development of a domestic nuclear fuel cycle, the U.S. needs to develop additional uranium mines in order to achieve its target of energy security through nuclear power. We believe Pine Ridge holds the potential to positively contribute to that goal," continued Mr. Wheatley.

2026 Pine Ridge Drill Program

The Drill Program will include nearly 120 drill holes totaling approximately 36,000 meters. Drilling is expected to be completed using one drill rig operating from July through December 2026, with the program potentially extending into January 2027.

The Drill Program will build on the successful 2025 drill program which confirmed widespread uranium mineralization, demonstrated continuity of mineralization across multiple areas, and identified at least 25 mineralized roll fronts contained within multiple major sandstone packages.

Frontier’s geology team has integrated the results of the 2025 drill program with Pine Ridge’s extensive historical drilling and geophysical database to refine the geological model and prioritize targets for the Drill Program. The Drill Program is designed to expand and further define priority mineralized trends, test additional prospective sandstone horizons, and advance Pine Ridge toward the definition of a maiden mineral resource estimate.

Results from the 2025 drill program illustrate the continuity of the stacked roll-front systems identified across Pine Ridge and confirm mineralized zones within multiple major sandstone packages in the eastern and southwestern portions of Pine Ridge. These mineralized zones generally occur at depths of approximately 200 meters to 400 meters and are separated by laterally extensive fine-grained units that provide geological and hydrological confinement, supporting Pine Ridge’s potential suitability for future In-Situ Recovery development.

Importantly, mineralization intersected in the southwestern portion of Pine Ridge appears to be hosted within a stratigraphically lower sandstone package than the mineralized sandstone packages identified in the eastern portion of Pine Ridge. This interpretation suggests that additional prospective areas and sandstone horizons may be present across Pine Ridge.

In conjunction with preparations for the 2026 exploration program, Frontier expanded the Pine Ridge claim block through the addition of 54 federal mining claims, comprising approximately 854 acres.

Pine Ridge Uranium Project

Pine Ridge is an advanced In-Situ Recovery ("ISR") uranium exploration project located in the southwestern Powder River Basin of Wyoming, the premier uranium-producing basin in the United States.

Pine Ridge is surrounded by existing uranium projects held by established uranium operators and explorers. It is located approximately 15 kilometers from Cameco’s Smith Ranch processing facility, which has a licensed capacity of 5.5 million pounds of U₃O₈ p.a. Smith Ranch mill is one of the largest uranium production facilities in the United States.

Pine Ridge benefits from an extensive historical exploration database comprising 1,311 historical drill holes totaling more than 22,825 meters of drilling, supplemented by 114 drill holes totaling 38,000 meters completed by Frontier during the 2025 exploration program. This combined dataset provides the foundation for Pine Ridge’s geological interpretation and the targeting of the Drill Program.

Wyoming Uranium Mining Industry

The Pine Ridge Uranium Project is located in the southwestern Powder River Basin of Wyoming, the premier U.S. uranium basin. Historically, the Powder River Basin is the most significant area for uranium production in U.S. primarily via ISR production methods, and Wyoming has produced nearly 240 Mlbs U₃O₈ since 1951.

ISR uranium mining offers significant advantages over conventional hard rock mining, particularly in terms of environmental impact and cost efficiency. ISR requires no large-scale open pits or underground tunnels, minimizing surface disturbance and eliminating the need for waste rock and tailings storage. This translates to a much lower environmental footprint, reduced water usage, and streamlined permitting processes. Additionally, ISR operations typically have lower capital expenditures and operating costs due to their simpler infrastructure requirements and more efficient extraction methods.
