F3 - NEW Discovery - 33.0m Radioactivity with 0.56m >10,000 cps at Broach Lake
F3 Uranium Corp (TSXV: FUU) (OTCQB: FUUFF) has announced a significant new uranium discovery at Broach Lake, located 12km south of the JR Zone. Drillhole PLN25-205 intersected radioactivity over 33.0m, including a notable 0.56m section of high radioactivity exceeding 10,000 cps with a peak of 37,700 cps at 398.34m depth.
The discovery is particularly significant as it occurs within the Clearwater Domain, an area historically considered less prospective for uranium mineralization. The mineralization starts at a vertical depth of 325 meters from surface and is hosted within chloritic and clay altered orthogneisses.
The company plans to continue drilling on section to better understand the mineralization controls before exploring along strike, which remains open in both directions. The discovery follows previous drilling attempts in the area, including PLN25-202 which showed initial potential with 720cps.
F3 Uranium Corp (TSXV: FUU) (OTCQB: FUUFF) ha annunciato una importante nuova scoperta di uranio a Broach Lake, situata a 12 km a sud della zona JR. Il foro di sondaggio PLN25-205 ha intercettato radioattività su 33,0 m, inclusa una sezione significativa di 0,56 m con alta radioattività superiore a 10.000 cps, con un picco di 37.700 cps a 398,34 m di profondità.
La scoperta è particolarmente rilevante poiché si trova nel Clearwater Domain, un’area storicamente considerata meno promettente per la mineralizzazione dell’uranio. La mineralizzazione inizia a una profondità verticale di 325 metri dalla superficie ed è ospitata in ortogneiss alterati da clorite e argilla.
L’azienda prevede di continuare la perforazione sulla sezione per comprendere meglio i fattori che controllano la mineralizzazione, prima di esplorare lungo la direzione della vena, che rimane aperta in entrambe le direzioni. La scoperta segue precedenti tentativi di perforazione nell’area, incluso il foro PLN25-202 che aveva mostrato un potenziale iniziale con 720 cps.
F3 Uranium Corp (TSXV: FUU) (OTCQB: FUUFF) ha anunciado un importante nuevo descubrimiento de uranio en Broach Lake, ubicado a 12 km al sur de la Zona JR. El taladro PLN25-205 intersectó radioactividad durante 33,0 m, incluyendo una sección notable de 0,56 m con alta radioactividad superior a 10,000 cps, con un pico de 37,700 cps a 398,34 m de profundidad.
El descubrimiento es especialmente significativo ya que ocurre dentro del Clearwater Domain, un área históricamente considerada menos prometedora para la mineralización de uranio. La mineralización comienza a una profundidad vertical de 325 metros desde la superficie y se aloja en ortogneises alterados con clorita y arcilla.
La compañía planea continuar perforando en la sección para comprender mejor los controles de la mineralización antes de explorar a lo largo de la extensión, que permanece abierta en ambas direcciones. El descubrimiento sigue a intentos previos de perforación en la zona, incluyendo PLN25-202 que mostró un potencial inicial con 720 cps.
F3 Uranium Corp (TSXV: FUU) (OTCQB: FUUFF)는 JR 존에서 남쪽으로 12km 떨어진 Broach Lake에서 중대한 새로운 우라늄 발견을 발표했습니다. 시추공 PLN25-205는 33.0m 구간에 걸쳐 방사능을 확인했으며, 그 중 0.56m 구간에서는 10,000 cps를 초과하는 높은 방사능이 나타났고, 398.34m 깊이에서 최대 37,700 cps를 기록했습니다.
이 발견은 우라늄 광화 가능성이 낮다고 여겨졌던 Clearwater Domain 내에서 이루어졌다는 점에서 특히 중요합니다. 광화는 지표면에서 수직으로 325미터 깊이부터 시작되며, 클로리트 및 점토 변형된 정장편마암 내에 분포합니다.
회사는 광화 제어 요인을 더 잘 이해하기 위해 단면 시추를 계속 진행할 계획이며, 이후에는 양방향으로 열려 있는 연장선을 따라 탐사를 진행할 예정입니다. 이번 발견은 이전에 지역에서 시도된 시추 작업들, 예를 들어 720 cps의 초기 가능성을 보였던 PLN25-202 이후에 이루어졌습니다.
F3 Uranium Corp (TSXV : FUU) (OTCQB : FUUFF) a annoncé une importante nouvelle découverte d’uranium à Broach Lake, situé à 12 km au sud de la zone JR. Le forage PLN25-205 a intercepté une radioactivité sur 33,0 m, incluant une section notable de 0,56 m à haute radioactivité dépassant 10 000 cps, avec un pic à 37 700 cps à une profondeur de 398,34 m.
Cette découverte est particulièrement significative car elle se situe dans le Clearwater Domain, une zone historiquement considérée comme moins prometteuse pour la minéralisation en uranium. La minéralisation commence à une profondeur verticale de 325 mètres depuis la surface et se trouve dans des orthogneiss altérés par chlorite et argile.
La société prévoit de poursuivre les forages sur cette section afin de mieux comprendre les contrôles de la minéralisation avant d’explorer le long de la direction, qui reste ouverte dans les deux sens. Cette découverte fait suite à des tentatives de forage antérieures dans la région, notamment PLN25-202 qui avait montré un potentiel initial avec 720 cps.
F3 Uranium Corp (TSXV: FUU) (OTCQB: FUUFF) hat eine bedeutende neue Uranentdeckung bei Broach Lake bekanntgegeben, das 12 km südlich der JR-Zone liegt. Das Bohrloch PLN25-205 durchteufte Radioaktivität über 33,0 m, einschließlich eines bemerkenswerten Abschnitts von 0,56 m mit hoher Radioaktivität von über 10.000 cps und einem Spitzenwert von 37.700 cps in 398,34 m Tiefe.
Die Entdeckung ist besonders bedeutend, da sie im Clearwater Domain liegt, einem Gebiet, das historisch als weniger aussichtsreich für Uranmineralisierung galt. Die Mineralisierung beginnt in einer vertikalen Tiefe von 325 Metern von der Oberfläche und befindet sich in chlorit- und tonveränderten Orthogneisen.
Das Unternehmen plant, die Bohrungen im Querschnitt fortzusetzen, um die Steuerungsfaktoren der Mineralisierung besser zu verstehen, bevor es entlang des Streichens weiter exploriert, das in beide Richtungen offen bleibt. Die Entdeckung folgt auf frühere Bohrversuche in der Region, darunter PLN25-202, das mit 720 cps erstes Potenzial zeigte.

On New Trend - 12km South of JR Zone
Kelowna, British Columbia--(Newsfile Corp. - April 15, 2025) - F3 Uranium Corp (TSXV: FUU) (OTCQB: FUUFF) ("F3" or "the Company") is pleased to announce a new discovery with drillhole PLN25-205 which intersected radioactivity over a total of 33.0m including 0.56m of high radioactivity (>10,000 cps) with a peak of 37,700 cps at 398.34m. The drillhole is still currently in progress, however additional mineralization is not expected.
2025 Handheld Spectrometer Highlights:
Broach Lake: PW Area
PLN25-205 (line 11310S):
- 0.5m interval with radioactivity of 340 cps between 340.0 and 340.5m, and
- 0.5m interval with radioactivity of 440 cps between 347.5 and 348.0m, and
- 0.5m interval with radioactivity of 370 cps between 366.0 and 366.5m, and
- 8.0m interval with radioactivity peaking 2,500 cps between 373.0m and 381.0m, and
- 23.5m interval with radioactivity peaking 37,700 cps between 384.0m and 407.5m, including
- 0.56m composite mineralization >10,000 cps between 389.75m and 398.56m
Sam Hartmann, Vice President Exploration, commented:
“On March 18th we announced anomalous radioactivity at a newly emerging area 12km south of the JR Zone, showing great initial potential with drillhole PLN25-202, peaking at 720cps. This was followed up with an aggressive step back with PLN25-203, which aimed to locate a MLTDEM ground conductor. Encouraging alteration was encountered at depth corresponding with the approximate down-dip projection of the radioactive intervals in PLN25-202, but no anomalous radioactivity was noted. PLN25-204 then tested 60m up-dip of PLN25-202, successfully intersecting the targeted rock units but again with no anomalous radioactivity. Despite these results we decided on one more follow-up to PLN25-202 targeting approximately 50m down-dip (see Image 1 for cross section), this time successfully intersecting high-grade pitchblende mineralization hosted within competent but strongly chloritic and clay altered orthogneisses (see Image 2), in the hanging wall of an unmineralized fault with mineralization starting at a vertical depth of 325 meters from surface. This discovery is particularly meaningful as it is within the Clearwater Domain – a geological package predominantly thought to consist of intrusive rocks and historically considered less prospective for uranium mineralization. These drillholes contain significant intercepts of dioritic rocks – but also the strained and structurally disturbed orthogneisses we target. This strong initial intercept in PLN25-205 is the perfect analog to the approach of the technical team at F3 Uranium; to think out of the box and be persistent. After we finish drilling this hole, we plan to continue drilling on section to improve our understanding of the controls on the mineralization, before moving laterally along strike, which is open in both directions”.

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 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.
The Company considers uranium mineralization with assay results of greater than 1.0 weight % U3O8 as “high grade” and results greater than 20.0 weight % U3O8 as “ultra-high grade”.
All depth measurements reported are down-hole and true thicknesses are yet to be determined.
