Manhattan Uranium Discovery (MAUUF) reported historical drilling results and a modernized database for its Lisbon Valley uranium project in Utah.
The company compiled 499 historical drill holes, mainly on the North Lisbon property, to build a 3D targeting model. The highest-grade historical gamma intercept is 3.70% eU₃O₈ over 5.2 ft in hole N-1, more than ten times the district’s reported 0.30% historical production grade. In the database, 266 holes (53%) returned mineralized intercepts above 0.15% eU₃O₈, with mineralized intercepts averaging 0.28% eU₃O₈, comparable to the district’s reported 0.30% U₃O₈ production grade.
Manhattan has ranked 36 high-priority historical intercepts for follow-up and has generated preliminary 3D uranium target domains. All grades are based on unverified historical gamma data used for exploration targeting only, and no current mineral resource or reserve estimate exists at Lisbon Valley.
Manhattan Uranium Discovery (OTCQB: MAUUF, TSXV: MANU) appointed critical minerals and national security specialist Dennis W. Bartow II as Strategic Advisor, effective August 13, 2026. He will help the company engage U.S. federal policymakers, agencies and financing institutions as it advances its portfolio of past-producing uranium mines in Utah, Colorado and Nevada.
According to Manhattan, Bartow’s background includes serving as U.S. Deputy Assistant Secretary of Defense for African Affairs Policy, Director of the Department of Defense Office of Small Business Programs overseeing about $90 billion in annual small business procurement, and founder/CEO of advisory firm Polemarchoi. Manhattan granted him 100,000 stock options at an exercise price of $0.22 per share, vesting over six months with a two-year term, subject to TSX Venture Exchange acceptance.
Manhattan Uranium (OTC: MAUUF) reported completion of a major historical data compilation for its permitted I-70 uranium project in the San Rafael district, Utah. The new digital database consolidates approximately 5,668 historical drill collar locations and 4,550 gamma-equivalent uranium intervals from 2,769 drill holes.
According to Manhattan Uranium, about 1,985 holes (72%) contain at least one interval grading ≥0.10% eU₃O₈, indicating widespread mineralization. High-grade historical intercepts include 1.22 m at 1.59% eU₃O₈ (GR-896-80) and 2.13 m at 0.86% eU₃O₈ (FC-20-67). An initial lithology model and digitized underground workings have been integrated to generate preliminary 3D uranium target domains, with priority drill targets now being defined for the upcoming field season. The company cautions that all grades are historical gamma-based equivalents, not verified chemical assays, and that no current mineral resource or reserve estimate has been established at I-70.
Manhattan Uranium Discovery (OTCQB:MAUUF) will begin trading on the OTCQB Venture Market in the U.S. on June 22 under symbol MAUUF, while retaining TSXV:MANU and FSE:J5B0 listings.
The company also signed U.S. and Canada-based marketing and investor relations agreements totaling US$400,000, subject to TSXV acceptance.
Manhattan Uranium (OTC: MAUUF) and Fortune Bay have started diamond drilling at the Murmac uranium project in Saskatchewan’s Athabasca Basin. The fully funded program totals ~5,000 metres across up to 25 targets at Murmac and Strike, initially testing 15 priority, shallow basement-hosted uranium targets at Murmac.
Manhattan Uranium (OTC: MAUUF) and Fortune Bay plan a fully funded, ~5,000 metre drill program starting June 2026 at the Murmac and Strike uranium projects in Saskatchewan. Up to 25 priority targets will be tested along ~63 km of conductive corridors on 19,877 hectares.
The option deal allows Manhattan to earn up to 70% by funding C$6M in exploration, paying C$1.35M in cash and issuing C$2.15M in shares. Previous work returned shallow high-grade uranium intervals at both projects.
Manhattan Uranium (OTC: MAUUF) received U.S. Forest Service approval of the Apex Plan of Operations, authorizing uranium exploration drilling at the Apex Project in Lander County, Nevada.
The decision allows construction of up to seven drill pads with just 0.93 acres of surface disturbance within a one-year work window, backed by an $18,636 reclamation bond.
Manhattan Uranium Discovery (OTC: MAUUF) outlined a district-scale uranium portfolio spanning 25 U.S. properties (25,099 acres) with 15 past-producing mines across Utah, Nevada, plus discovery-stage projects in Saskatchewan’s Athabasca Basin.
The company reports over $11.5 million in cash, fully funding 2026 drilling, highlighted by a 25–30 hole Athabasca program starting June 2026. Permitted and advanced projects include I-70 (San Rafael), North Lisbon (Lisbon Valley), La Sal/Blue Jay, and Nevada’s Apex mine, where drill permits are anticipated in H1 2026. Spencer MacLean has been appointed President, and several short-term investor relations and digital marketing agreements were signed, subject to TSXV acceptance. All historical resource estimates remain non-current under NI 43-101 and require verification.
