F4 URANIUM CONFIRMS TERMINATION OF HEARTY BAY OPTION AGREEMENT BY TRACTION URANIUM

F4 Uranium Corp. has received formal notice of termination dated July 15, 2026, from Traction Uranium Corp. regarding the mineral property option agreement dated Dec. 9, 2021, as amended on Feb. 28, 2023, and July 22, 2025, relating to the Hearty Bay property in Saskatchewan's Athabasca basin.

Pursuant to Section 10.1(b) of the option agreement, Traction has voluntarily terminated the agreement. The termination will become effective on July 30, 2026. As a result, F4 will retain 100-per-cent ownership of the Hearty Bay property.

Raymond Ashley, chief executive officer of F4 Uranium, commented:

"We thank Traction for their contributions to the Hearty Bay project. F4 now holds a 100-per-cent interest in this prospective property and will evaluate next steps to advance exploration. We continue to be encouraged by the project's potential and remain focused on discovering the bedrock source of the high-grade mineralized boulder train on Isle Brochet, where assays returned up to 8.23 per cent U3O8. Future exploration may be undertaken by the company independently or in collaboration with a new strategic partner."

About the Hearty Bay property

The Hearty Bay property comprises seven mineral claims totalling 11,173 hectares on the northern margin of the Athabasca basin in Saskatchewan, located approximately 20 kilometres west of the Fond-du-Lac uranium deposit. The property is highlighted by the historic Isle Brochet boulder field, including the Wolfe and Jackfish radioactive boulder trains. These trains contain mineralized boulders with historic assays up to 3.54 per cent U3O8 (triuranium octoxide).

Prospecting by F3 Uranium in 2019 identified 45 new mineralized boulders returning assays of up to 8.23 per cent U3O8, with more than 24 per cent of samples exceeding 1 per cent U3O8. Recent exploration includes a 14-hole drill program in 2022, subglacial till sampling in 2022 to 2023, and analysis of 84 till samples in 2024 that identified a uranium dispersal fan and refined ice-flow vectors toward the Athabasca basin margin.

A gravity survey was also completed to generate new drill targets.

A winter 2024 drill program to test these targets was limited to a single hole due to poor ice conditions, leaving most targets untested.

About F4 Uranium Corp.

F4 Uranium is a Canadian uranium exploration company focused on the Athabasca basin in Northern Saskatchewan, led by the management and exploration team behind multiple uranium discoveries in the basin, including most recently Patterson Lake North and Broach Lake. The project portfolio comprises 16 wholly owned properties totalling approximately 157,000 hectares, several of which sit near established uranium deposits including Paladin's Triple R, NexGen Energy's Arrow and IsoEnergy's Hurricane. The assets were spun out of F3 Uranium in 2024. F4's exploration program is split between the west and east sides of the Athabasca basin, with the company operating as both an explorer and project generator providing investors early stage exposure to the basin.

We seek Safe Harbor.
