F4 IDENTIFIES MULTIPLE PROSPECTIVE TRENDS AT GREY ISLAND

F4 Uranium Corp. has conducted an airborne mobile magnetotellurics (mobile MT) survey over the Grey Island project in the southern Athabasca basin has yielded very favourable geophysics results indicating multiple large-scale linear resistivity features, which represent prospective corridors and provide promising target areas. The Grey Island project is located 70 kilometres to the west of the Key Lake mine owned by Cameco and Orano, and 60 km to the east of Cameco's Centennial uranium deposit.

The survey was completed by Expert Geophysics Surveys Inc. and provided an up-to-date data set characterizing the property's subsurface features and establishing an initial framework for future geological evaluation and follow-up exploration.

The Grey Island has seen very limited historical exploration; it is located near the Cable Bay shear zone, a regional structural feature that is interpreted to be a prospective conductive corridor with known mineralized occurrences such as drill hole ND0801 drilled by Nuinsco, intersected 707 parts per million uranium in a sandstone sample at the unconformity, just 12 km to the west of the Grey Island project. To the east, CanAlaska's Cree East property has seen assays up to 0.015 per cent U3O8 (triuranium octoxide) approximately 10 km from Grey Island. Only one documented drill hole FLM-08-05 has been completed on the property itself. This hole reported bleaching and alteration in the sandstone, along with pyritic and graphitic alteration in the basement rocks -- the early geological signatures the company looks for within conductive packages as indicators of possible uranium-bearing systems.

Erik Sehn, vice-president of exploration, commented:

"Grey Island represents our largest, and most underexplored land package in the southern Athabasca basin. With only a single historic drill hole and outdated geophysical data available, we consider the mobile MT survey as an important first step to assess the property for conductive trends. The results of this survey display large, linear resistivity low anomalies and merit further target generation, initially with detailed ground geophysics and eventually drilling."

About Grey Island

F4 Uranium's 100-per-cent-owned Grey Island project lies within the Southern Athabasca basin is located approximately 60 kilometres northeast of the Key Lake mine and approximately 10 km to the east of the Cable Bay shear zone. The property consists of 22 claims spanning an area of 47,913 hectares, but despite the large size is primarily unexplored with only one drill hole being completed on the property.

About F4 Uranium Corp.

F4 Uranium is a Canadian uranium exploration company focused on the Athabasca basin in Northern Saskatchewan, and the latest uranium explorer, lead by the same management and exploration team with a legacy of discovery successes. The project portfolio includes 17 wholly owned properties totalling roughly 157,000 hectares, many of which are near uranium deposits including Paladin's Triple R, Nexgen Energy's Arrow and IsoEnergy's Hurricane projects. The assets were spun out of F3 Uranium in 2024, where the technical and management team made their third, and more recently fourth uranium discoveries at Patterson Lake North and Broach Lake. 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 providing shareholders renewed exposure at an early stage.
