F4 Uranium Corp (TSXV: FFU) will begin ground EM geophysics at Murphy Lake, located 5 kilometers South of IsoEnergy’s High-Grade Hurricane Deposit and 4 kilometers east of Cameco’s La Rocque Lake Uranium Zone.
EarthEx Geophysical Solutions will complete 9.2 line-kilometers of Moving Loop Electromagnetics on 4 lines. According to F4, this MLEM will build on previous ground geophysics by tightening the survey line spacing to test the areas around and between two known prospective conductor systems. (See Figure 1).
The company intends to integrate the results into the project model to guide the upcoming drill program planned for late spring of 2026.
UraniumX Discovery Corp is funding the Murphy work program per the terms of the Option Agreement to acquire up to a 70% interest in the Murphy Lake Property (see F4 news release dated February 2, 2026). F4 will be the operator during the earn-in period.
In 2022, drilling by F4 intersected elevated uranium geochemistry and indicators associated with uranium mineralization, including hematite and limonite alteration in sandstone and graphitic shear zones in the basement. Drill hole ML22-006 hit 0.242% U3O8 and a 4.2m wide deformation zone. ML22-012, 1.4 kilometers away at the northern end of the property, was interpreted to have just overshot the conductive basement target but intersected strong 56 ppm uranium in a 0.5m sandstone sample just above the unconformity.
Erik Sehn, VP Exploration, stated that F4 Uranium considers Murphy Lake one of its best exploration properties due to its early indicators and proximity to uranium discoveries, including IsoEnergy’s Hurricane and Cameco’s La Rocque Lake Project. Sehn added that the company and partner UraniumX look forward to completing the geophysical program to assist in target generation for the next drill program and that the team is eager to return to the project since 2022. The geophysical program is an important step before further drill testing the areas around ML22-006 and ML22-012.
F4’s 609-hectare Murphy Lake Property is located in the north-eastern corner of the Athabasca Basin, 30 km northwest of Orano’s McLean Lake deposits, 5 km south of ISOEnergy’s Hurricane Uranium Deposit and 4 km east of Cameco’s La Rocque Lake Uranium Zone where drill hole Q22-040 intersected 29.9% U3O8 over 7.0 m. The 2022 maiden drill program at the Murphy Lake Property consisted of 14 completed drillholes totaling 6,850m; drill hole ML22-006 intersected 0.065% U3O8 over 2.5m from 322.5m to 324.5m, including 0.242% U3O8 over 0.5m.
Sam Hartmann, P.Geo., President & Chief Operation Officer of F4, and a qualified person as defined by National Instrument 43-101 – Standards of Disclosure for Mineral Projects, reviewed and approved the technical information in this news release.
The news release also refers to neighboring properties in which F4 Uranium has no interest. Mineralization on those neighboring properties is not necessarily indicative of mineralization on the Murphy Lake Property.
For additional information on the Murphy Lake Property, please refer to the National Instrument 43-101 Report titled “Technical Report For The Murphy Lake Project, NE Athabasca Basin, Saskatchewan, Canada” effective March 20, 2024, available at www.sedarplus.ca.
F4 Uranium is a Canadian uranium exploration company focused on the Athabasca Basin in northern Saskatchewan. The project portfolio includes 17 wholly owned properties totaling roughly 157,000 ha. The assets were spun out of F3 Uranium in 2024. F4’s core focus will be split between the west and east sides of the Athabasca Basin as the company is establishing itself as an explorer and project generator.
