F3 - INCREASES MINERALIZED STRIKE LENGTH OF TETRA ZONE SYSTEM TO 1.2KM

Geochemistry results from relogging and maiden geochemical analysis of historic holes on F3 Uranium Corp.'s Broach property have returned 423 parts per million uranium over 0.5 metre, 1.2 kilometres southeast along strike from the recently discovered Tetra zone. This development has significantly increased the prospective strike length of the mineralized corridor that hosts the Tetra zone, where drilling is currently in progress.

The F3 team completed comprehensive relogging of historic drill holes on the Broach property, including PAT-15-001, PAT-16-002 and PAT-16-004. Relogs noted intense clay alteration and bleaching around the Athabasca unconformity, including fracture-controlled silicification, particularly in PAT-16-002; these are features often found in proximity to uranium mineralization. Drill holes were resampled following F3's internal sampling procedures and geochemical results are highlighted by drill hole PAT-16-002, which returned 423 parts per million uranium over 0.5 metre from 164.5 to 165.0 metres. PAT-16-002 is located 1.2 kilometres to the southeast of Tetra zone.

Hole PLN25-201, drilled earlier this year, which the company interprets to have overshot the ground conductor, was collared approximately 300 metres to the northeast of PAT-16-002 and displays similar alteration, including intense bleaching and alteration just below the unconformity.

Highlights of historic drill core analysis:

• PAT-16-002:
  • 5.5 metres at 63 parts per million uranium (160.0 metres to 165.5 metres);
  • Including 0.5 metre at 423 parts per million uranium (164.5 metres to 165.0 metres).

Sam Hartmann, vice-president, exploration, commented: "In 2016, a previous operator cored two drill holes targeting gravity anomalies approximately 1.2 kilometres southeast of the Tetra zone. One of these, PAT-16-002, was drilled 300 metres from our recent PLN25-201 hole, which was the first hole to target the ground conductor we defined last winter and now host to the Tetra zone. As no core samples from these historic holes were previously sent for analysis, F3 conducted geological relogging and then maiden geochemical core sample analysis of the PAT-16-002 and PAT-16-004 cores. In PAT-16-002, we recognized strong clay alteration in the upper basement, with a 0.5-metre interval returning 423 ppm uranium -- the highest uranium value recorded in any single exploration core sample from the PLN project, outside of the JR and Tetra zones. Only three other core samples across the project have approached this level, including one from PLN14-019 at 397 ppm, which sparked the 2022 exploration of the A1 conductor and led to the discovery of the JR zone, and two from PLN24-152, which intersected 0.014 per cent U3O8 [triuranium octoxide] over seven metres, including 0.051 per cent U3O8 over 0.5 metres (see July 30, 2024, news release). The striking similarity in lithologies and alteration styles, coupled with highly anomalous uranium values over a 1.2-kilometre distance, reinforces our belief of a potentially expansive mineralized system along strike from Tetra, significantly enhancing further discovery potential."

Samples from the drill core are split into half sections on site. Where possible, samples are standardized at 0.5-metre downhole intervals. One-half of the split sample is sent to SRC Geoanalytical Laboratories (an SCC ISO/IEC 17025:2005 accredited facility) in Saskatoon, Sask., while the other half remains on site for reference. Analysis includes a 63-element suite, including boron by ICP-OES, uranium by ICP-MS, and gold analysis by ICP-OES and/or AAS.

All depth measurements reported are downhole and true thicknesses are yet to be determined.

About the Patterson Lake North project

The company's 42,961-hectare 100-per-cent-owned Patterson Lake North (PLN) project is located just within the southwestern edge of the Athabasca basin in proximity to Paladin's Triple R and NexGen Energy's Arrow high-grade uranium deposits, an area poised to become the next major area of development for new uranium operations in Northern Saskatchewan. The PLN project consists of the 4,074-hectare Patterson Lake North property hosting the JR zone uranium discovery approximately 23 kilometres northwest of Paladin's Triple R deposit, the 19,864-hectare Minto property and the 19,022-hectare Broach property hosting the Tetra zone, F3's newest discovery 13 kilometres south of the JR zone. All three properties comprising the PLN project are accessed by Provincial Highway 955.

About F3 Uranium Corp.

F3 is a uranium exploration company, focusing on the high-grade JR zone and new Tetra zone discovery 13 kilometres to the south in the PW area on its PLN project in the western Athabasca basin. F3 currently has three properties in the Athabasca basin: Patterson Lake North, Minto and Broach. The western side of the Athabasca basin in Saskatchewan is home to some of the world's largest high-grade uranium deposits, including Paladin's Triple R project and NexGen's Arrow project.
