MANHATTAN URANIUM RECEIVES APPROVAL OF THE APEX PROJECT PLAN OF OPERATIONS AUTHORIZING DRILLING AT NEVADA'S LARGEST HISTORICAL PAST PRODUCING URANIUM MINE

The U.S. Forest Service has approved the Apex plan of operations, authorizing drilling to advance high-priority uranium exploration at Manhattan Uranium Discovery Corp.'s Apex uranium project in Lander county, Nevada. This approval clears the way for the construction of up to seven drill pads, a staging area, new temporary road access and limited cross-country travel.

Key highlights:

• Drill permit secured: U.S. Forest Service has approved the Apex plan of operations, delivering a critical regulatory milestone at the Apex uranium project in Lander county, Nevada.
• Up to seven drill pads now authorized: This approval greenlights construction of up to seven drill pads, a staging area, new temporary road access and limited cross-country travel, while still limiting surface disturbance to just 0.93 acre.
• Advances Nevada's largest past-producing uranium mine: The approval clears the path to test and expand high-grade historical uranium mineralization at the Apex uranium project -- Nevada's largest past-producing uranium mine -- which produced approximately 50 per cent of Nevada's all-time uranium output, including standout historical intercepts of 34.1 metres at 0.37 per cent U3O8 and 15.2 metres at 0.51 per cent U3O8.
• Minimal environmental footprint: The approved program is designed for low-impact exploration within a one-year window from the start of work on National Forest lands, consistent with Manhattan's commitment to responsible development.
• Strengthens consolidated U.S. uranium platform: The approval delivers a key regulatory milestone at the Apex project, enhancing Manhattan's premier North American pure-play uranium platform of 15 past-producing mines on 25 underexplored U.S. properties following the recent acquisitions of Urano Energy Corp. and Pegasus Resources Inc.
• National energy security priorities: The approval supports recent U.S. executive orders aimed at expanding domestic uranium production, strengthening the nuclear fuel supply chain, and advancing energy independence and national security.

"Receipt of our Apex plan of operations approval from the U.S. Forest Service is a pivotal milestone for Manhattan. Nevada has never seen a modern drill program on its largest historical uranium producer and we are now positioned to change that. Years in the making, this approval comes at a critical time as domestic uranium supply has become a national priority," stated William Sheriff, chairman of Manhattan.

"Apex has always stood out in our portfolio, Nevada's largest past-producing uranium mine, with historical intercepts of up to 34.1 metres of 0.37 per cent U3O8 and surface sampling returning up to 1.00 per cent U3O8 across approximately three kilometres of showings. This plan of operations approval clears the path for the first modern drill program in the project's history," stated Galen McNamara, chief executive officer of Manhattan.

The Apex plan of operations approval

The U.S. Forest Service has formally approved the Apex plan of operations, authorizing Manhattan to conduct mineral exploration activities on National Forest System lands within the Austin-Tonopah Ranger district of the Humboldt-Toiyabe National Forest in Lander county, Nevada. The approved program includes the construction of up to seven drill pads, a staging area, new temporary road access and limited cross-country travel. Total surface disturbance associated with the program is limited to just 0.93 acre and is scheduled to occur within a one-year period once surface-disturbing activities commence.

Under U.S. Forest Service regulations (36 CFR 228 Subpart A), a plan of operations is the required permitting instrument for mineral exploration projects on National Forest lands that involve surface disturbance beyond casual use. The Apex plan was originally submitted in September, 2022, and underwent multiple rounds of review before receiving final approval on May 18, 2026, following the signing of the findings and applicability of no extraordinary circumstances (FANEC) on May 14, 2026. This approval represents a significant derisking milestone for the project, confirming that the proposed low-impact exploration activities are consistent with environmental standards and forest management objectives.

The approval is conditional upon the company posting the required financial assurance of $18,636 to guarantee reclamation of the disturbed areas. Once the bond is accepted and confirmed by the U.S. Forest Service, Manhattan is expected to receive a letter authorizing the commencement of surface-disturbing work. The company will continue to work closely with U.S. Forest Service staff on finalizing the bonding process and ensuring full compliance with all federal, state and local requirements.

Additionally, the company developed and submitted a comprehensive uranium safety management plan as a key component of the final plan of operations package. This detailed plan establishes site-specific protocols for radiation safety, environmental monitoring, worker protection and best management practices tailored specifically to uranium exploration activities on National Forest lands. The pro-active preparation and submission of the uranium safety management plan played an important role in demonstrating the company's commitment to safe, responsible operations and contributed directly to securing final approval from the U.S. Forest Service.

Alignment with U.S. national energy security priorities

This approval aligns directly with President Trump's executive order "Reinvigorating the Nuclear Industrial Base," signed on May 23, 2025. The order directs federal agencies to strengthen America's domestic nuclear fuel supply chain, expand uranium mining and processing capacity, and reduce reliance on foreign sources of uranium in support of national energy security, energy independence and economic growth. By securing plan of operations approval for the Apex project -- historically Nevada's largest past-producing uranium mine -- Manhattan is positioned to contribute meaningfully to these national priorities through responsible, low-impact domestic uranium exploration.
