F3 Uranium Corp (TSXV: FUU) (OTCQB: FUUFF) has announced significant radioactive intervals at its Patterson Lake North Project's Tetra Zone. The company reported its widest intervals of radioactivity to date, with PLN25-217 intersecting a total of 67.0m composite radioactivity, including 49.0m of continuous radioactivity. PLN25-212 yielded the second-widest interval with 39.5m composite radioactivity.

The company is planning a ground geophysical program to improve conductor modeling around the Tetra Zone, which will support larger step-outs and potentially reduce required drill holes. Additionally, F3 completed two drill holes at the JR Zone, with assays to be included in their maiden resource estimate expected in Q4.

F3 Uranium Corp (TSXV: FUU) (OTCQB: FUUFF) ha annunciato intervalli radioattivi significativi nella zona Tetra del suo progetto Patterson Lake North. La società ha riportato i suoi intervalli di radioattività più ampi finora, con il foro PLN25-217 che ha intercettato un totale di 67,0 m di radioattività composita, inclusi 49,0 m di radioattività continua. Il foro PLN25-212 ha registrato il secondo intervallo più ampio con 39,5 m di radioattività composita.

La società sta pianificando un programma geofisico a terra per migliorare la modellazione dei conduttori intorno alla zona Tetra, supportando estensioni maggiori e potenzialmente riducendo il numero di fori di perforazione necessari. Inoltre, F3 ha completato due fori di perforazione nella zona JR, con le analisi che saranno incluse nella loro prima stima delle risorse prevista per il quarto trimestre.

PLN25-212 registró el segundo intervalo más amplio con 39,5 m de radioactividad compuesta.

La empresa planea un programa geofísico terrestre para mejorar el modelado de conductores alrededor de la Zona Tetra, lo que apoyará mayores extensiones y posiblemente reducirá la cantidad de perforaciones necesarias. Además, F3 completó dos perforaciones en la Zona JR, cuyos ensayos se incluirán en su estimación inicial de recursos esperada para el cuarto trimestre.

F3 Uranium Corp (TSXV: FUU) (OTCQB: FUUFF)는 Patterson Lake North 프로젝트의 Tetra 존에서 중요한 방사성 구간을 발표했습니다. 회사는 지금까지 가장 넓은 방사성 구간을 보고했으며, PLN25-217 시추공은 총 67.0m 복합 방사성 구간을 교차했으며 그중 49.0m는 연속 방사성 구간입니다. PLN25-212는 두 번째로 넓은 구간인 39.5m 복합 방사성 구간을 기록했습니다.

회사는 Tetra 존 주변의 전도체 모델링을 개선하기 위해 지상 지구물리학 프로그램을 계획 중이며, 이는 더 큰 확장과 필요한 시추공 수를 줄이는 데 도움이 될 것입니다. 또한 F3는 JR 존에서 두 개의 시추공을 완료했으며, 분석 결과는 4분기에 예정된 최초 자원 추정치에 포함될 예정입니다.

La société a rapporté ses intervalles de radioactivité les plus larges à ce jour, avec le forage PLN25-217 interceptant un total de 67,0 m de radioactivité composite, dont 49,0 m de radioactivité continue. PLN25-212 a enregistré le deuxième intervalle le plus large avec 39,5 m de radioactivité composite.

La société prévoit un programme géophysique au sol pour améliorer la modélisation des conducteurs autour de la zone Tetra, ce qui soutiendra des extensions plus importantes et pourrait réduire le nombre de forages nécessaires.

F3 Uranium Corp (TSXV: FUU) (OTCQB: FUUFF) hat bedeutende radioaktive Intervalle in der Tetra-Zone seines Patterson Lake North Projekts bekannt gegeben. Das Unternehmen meldete seine breitesten radioaktiven Intervalle bisher, wobei PLN25-217 insgesamt 67,0 m zusammengesetzte Radioaktivität durchteufte, darunter 49,0 m kontinuierliche Radioaktivität. PLN25-212 erzielte das zweitbreiteste Intervall mit 39,5 m zusammengesetzter Radioaktivität.

Das Unternehmen plant ein geophysikalisches Bodenprogramm zur Verbesserung der Modellierung von Leitern um die Tetra-Zone, was größere Erweiterungen unterstützt und möglicherweise die benötigte Anzahl an Bohrlöchern reduziert. Zusätzlich hat F3 zwei Bohrlöcher in der JR-Zone abgeschlossen, deren Analysen in ihre erwartete erste Ressourcenschätzung im vierten Quartal einfließen werden.

Largest Radioactive Intervals to Date on Project

Kelowna, British Columbia--(Newsfile Corp. - August 5, 2025) - F3 Uranium Corp (TSXV: FUU) (OTCQB: FUUFF) ("F3" or "the Company") is pleased to announce hand-held scintillometer results at Tetra Zone, where the widest intervals of radioactivity to date on the Patterson Lake North Project have been intersected with PLN25-217, which intersected a total of 67.0m composite radioactivity between 299.5m and 414.5m, including 49.0m of continuous radioactivity between 347.5m and 396.5m. Additionally, PLN25-212, approximately 23m up-dip of PLN25-217 and 31m along strike from the discovery hole PLN25-205, intersected the second widest interval to date with 39.5m composite radioactivity between 330.0m and 409.5m, including 27.5m of continuous radioactivity between 360.5m and 396.5m.

2025 Handheld Spectrometer Highlights:

Tetra Zone

PLN25-217 (line 11280S):

  • 0.5m interval with radioactivity between 299.5m and 300.0m, and
  • 0.5m interval with radioactivity between 315.5m and 316.0m, and
  • 7.5m interval with radioactivity between 336.5m and 344.0m, and
  • 49.0m interval with radioactivity between 347.5m and 396.5m, and
  • 9.0m interval with radioactivity between 399.5m and 408.5m, and
  • 0.5m interval with radioactivity between 414.0m and 414.5m.

PLN25-212 (line 11310S):

  • 2.5m interval with radioactivity between 330.0m and 332.5m, and
  • 0.5m interval with radioactivity between 346.5m and 347.0m, and
  • 0.5m interval with radioactivity between 354.0m and 354.5m, and
  • 27.5m interval with radioactivity between 360.5m and 388.0m, and
  • 6.0m interval with radioactivity between 394.0m and 400.0m, and
  • 2.5m interval with radioactivity between 407.0m and 409.5m.

Sam Hartmann, Vice President Exploration, commented:

"The substantial radioactive widths intersected in these drill holes were truly unexpected and highlight the significant potential we see at the Tetra Zone. Despite challenging drilling conditions and the non-traditional style of mineralization, each hole provides valuable insights into deposit model generation and drill plan adaptations. Notably, PLN25-217 confirms a theorized strike direction deviating from the current conductor model, and we will continue to explore this trend. To improve our conductor modeling around the Tetra Zone area, we are planning a ground geophysical program based on a tighter grid to support larger step-outs along the Tetra Zone, which stands to reduce the number of drill holes required for targeting. Additionally, we cored two drill holes at the JR Zone using casings set last winter with PLN25-215 and -216, which tested for crosscutting structures; those assays will be included in our maiden resource estimate, expected in Q4. We are very excited and look forward to further uncovering this unique system hosting the Tetra Zone."

Handheld spectrometer composite parameters:
1: Minimum Thickness of 0.5m
2: CPS Cut-Off of 300 counts per second
3: Maximum Internal Dilution of 2.0m

The natural gamma radiation detected in the drill core, as detailed in this news release, was measured in counts per second (cps) using a handheld Radiation Solutions RS-125 spectrometer which has been calibrated by Radiation Solutions Inc. The Company designates readings exceeding 300 cps on the handheld spectrometer (occasionally referred to as a scintillometer in industry parlance; this colloquial usage stems from historical naming conventions and the shared functionality of detecting gamma radiation between a spectrometer and a scintillometer)-as "anomalous", readings above 10,000 cps as "highly radioactive", and readings surpassing 65,535 cps as "off-scale". However, readers are cautioned that spectrometer or scintillometer measurements often do not directly or consistently correlate with the uranium grades of the rock samples and should be regarded solely as a preliminary indicator of the presence of radioactive materials.

Samples from the drill core are split into half sections on site. Where possible, samples are standardized at 0.5m down-hole intervals. One-half of the split sample is sent to SRC Geoanalytical Laboratories (an SCC ISO/IEC 17025: 2005 Accredited Facility) in Saskatoon, SK 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 down-hole and true thicknesses are yet to be determined.
