F3 RESUMES DRILL PROGRAM TARGETING A1 AND B1 SHEARS

F3 Uranium Corp.'s drill crews have mobilized to site, and drilling has resumed on the PLN property. Two diamond drills will focus on exploration drilling to the south of the JR zone for new mineralized zones along the approximately five-kilometre-long A1/B1 structural corridor.

The program will test new targets generated from the 30-hole winter drilling program along the A1 and B1 systems. Drilling will initially focus on the area where a significant reverse fault with vertical offset exceeding 100 metres, likely related to the Harrison fault or the Harrison fault itself, is interpreted to crosscut the main conductor system, including the A1 and B1 shears (see news release dated April 16, 2024). High-priority drill targets include both the A1 and B1 shear intersects with the large displacement reverse fault, the nose of the sandstone-hosted and strongly graphitic basement wedge, as well as the area directly between the A1 and B1 shears as defined by new ground electromagnetic which is also highlighted by a resistivity anomaly. The A1 shear itself will continue to be targeted for additional mineralized zones similar to the high-grade JR zone, starting with the area around PLN24-140 which was drilled within an 800 m long segment along the A1 shear with no previous drilling and intersected the strongest downhole radioactivity outside of the JR zone itself.

Sam Hartmann, PGeo, vice-president, exploration, commented:

"We have spent the last few weeks developing new geological and geophysical models, incorporating the wealth of data collected in drill holes and through geophysical inversions, and the F3 technical team is eager to resume the drill program with five drill holes already pre-ased from the end of the winter program. We see the potential for the PLN property, in particular the A1 and B1 conductor system, to host additional uranium mineralization based on structure and alteration. At the south end of A1, as well as at B1, new ground EM modelling has developed high-priority targets in close association with the crosscutting fault -- a reverse fault with a significant and favourable magnitude of vertical displacement, and we look forward to testing those structural confluences and the other new targets with the drill bit this spring and summer."

The ground gravity survey over the southwest sections of the PLN and Broach properties is set to resume later this week, surveying on land and infilling between areas that were surveyed from the lake ice this winter. This survey aims to add to the understanding of the A1 and B1 areas, in addition to other regional conductive corridors to the northeast and southwest of the A1/B1 corridor. Follow-up ground EM and resistivity will be carried out over gravity targets as appropriate, to further define distinct drill targets.

About Patterson Lake North

The company's 4,078-hectare, 100-per-cent-owned Patterson Lake North property (PLN) is located just within the southwestern edge of the Athabasca basin in proximity to Fission Uranium's Triple R and NexGen Energy's Arrow high-grade world-class uranium deposits which is poised to become the next major area of development for new uranium operations in Northern Saskatchewan. PLN is accessed by Provincial Highway 955, which transects the property, and the new JR zone uranium discovery is located 23 km northwest of Fission Uranium's Triple R deposit. The PLN property is part of the PLN project which also includes the Minto and Broach properties.
