Manhattan Appoints Former U.S. Deputy Assistant Secretary of Defense and Critical Minerals

Policy Expert Dennis Bartow as Strategic Advisor

Appointment strengthens Manhattan’s engagement with U.S. federal financing programs and domestic nuclear fuel

security policy

Vancouver, B.C. – August 13, 2026 – Manhattan Uranium Discovery Corp. (TSXV: MANU, OTC QB: MAUUF, FWB:

JB50) (“Manhattan” or the “Company”) is pleased to announce the appointment of Dennis W. Bartow II as Strategic

Advisor to the Company.

Mr. Bartow is a critical minerals and national security specialist who advises mining, refining and advanced manufacturing

companies across the United States and allied nations on securing U.S. government financing and building strategic

partnerships. He is the Founder, President and Chief Executive Officer of Polemarchoi Inc. (“Polemarchoi”), a strategic

advisory firm operating at the intersection of defense, energy, and critical minerals. Mr. Bartow will support Manhattan’s

engagement with U.S. federal policymakers, agencies and financing institutions as the Company advances its portfolio of

past-producing uranium mines across Utah, Colorado and Nevada, assets positioned to help address the domestic supply

gap at the centre of the U.S. nuclear energy renaissance.

Uranium’s designation as a critical mineral combined with growing federal support rebuilding the domestic nuclear fuel

supply places the Company’s U.S. mine portfolio squarely within the critical minerals policy framework. Mr. Bartow’s

experience with the federal programs is tied to that framework, including the Defense Production Act, the U.S. Department

of Energy Loan Programs Office, U.S. Department of Defense programs and Export -Import Bank of the United States

financing, is expected to support the Comp any’s efforts to engage the policy and funding mechanisms supporting

America’s nuclear energy agenda.

Galen McNamara, CEO and Director of Manhattan, commented: “Dennis served this country for nearly three decades in

uniform and went on to hold some of the most senior policy positions in the Pentagon. He has spent his career at the

intersection of policy, capital and industrial capability, and he understands the federal machinery as well as anyone in this

sector. As we advance a portfolio of past -producing American uranium assets at a moment when domestic fuel security

has become a national priority, his counsel on how Washington works will be of real value to our shareholders.”

Dennis Bartow, incoming Strategic Advisor, commented: "America gave away its nuclear fuel supply chain over three

decades and is now rebuilding it under time pressure. Manhattan is working the right end of that problem — brownfield

assets in proven districts, with existing permits and historic production behi nd them. I am glad to help the team navigate

the federal landscape as they advance these projects."

The Company has granted Mr. Bartow incentive stock options (each, an "Option") to purchase 100,000 common shares

at an exercise price of $0.22 per-share for a period of 2 years. The Options vest over a six-month period and are subject

to the acceptance of the TSX Venture Exchange.
