F3 Uranium launches summer drilling program at Patterson Lake North Project, Saskatchewan
F3 Uranium Corp. [TSXV: FUU; OTCQB: FUUFF; FSE: GL7] has commenced drilling under its 2026 summer exploration program across its 100%-owned Patterson Lake North (PLN) Project in the western Athabasca basin, Saskatchewan. With the JR and Tetra zones having proven what the company’s land-package-wide approach can deliver, drilling is now turning to a series of newly defined target areas on the Broach and Minto properties, several of which have reached the drill-ready stage for the first time.
The PLN project is one of the largest contiguous land packages held by a single explorer along the prospective southwestern margin of the Athabasca basin – host to Paladin’s Triple R and NexGen Energy’s Arrow deposits. While the JR and Tetra zones remain core to the company’s activity, continuing compilation and reinterpretation of historical and recently acquired geophysical, geological and geochemical data sets across the broader project have advanced several additional trends to the drill-ready stage.
The 2026 summer program is designed to systematically advance these new target areas in parallel with the continued evaluation of the company’s flagship discoveries. Drilling has commenced and is expected to initially comprise approximately 4,000 metres.
Sam Hartmann, vice-president of exploration, commented: “It’s exciting to finally be putting the drill into some of these areas. A number of them have been in our pipeline for years and it’s only now – with the additional geophysics we’ve completed and a systematic reinterpretation of our historic and newly acquired data sets — that they’ve matured to the drill-ready stage. This is the same land-package-wide, first-mover approach that delivered our discoveries at the JR and Tetra zones, and this summer, we finally get to test the most prospective of these targets in the field while continuing to unlock the significant untested potential that remains across all three properties.”
The 19,864-hectare Minto property hosts priority conductive corridors and geophysical anomalies along trend from the JR zone. Notably, the A4 trend spans nearly seven kilometres and runs parallel to – and shows a similar EM (electromagnetic) response to – the A1 conductor that hosts the JR zone. Summer drilling will advance the target area around historical drill hole PLN14-021 at A4 with at least one drill hole.
At the 19,022-hectare Broach property – host to the Tetra zone discovery – the 3-D DCIP and resistivity survey has been completed, with results currently being interpreted to refine drill targeting directly over the Tetra structure. Summer targeting on the Broach property is concentrated in two areas — the Patterson West area surrounding the Tetra zone and the Broach Lake South area.
Surrounding the Tetra zone discovery, the Patterson West area hosts numerous targets defined by EM conductors and gravity-low anomalies that exhibit geophysical signatures similar to those at the Tetra zone, of which four have been prioritized for drill testing under the 2026 summer program. F3 sampling of historical drill core in the area returned 423 parts per million (ppm) uranium (U) and identified intense bleaching, and these targets remain untested by follow-up drilling.
The Broach Lake South area hosts multiple drill-ready targets. These include target 1, a newly reinterpreted and steeply dipping conductor on the southern end, interpreted to be the continuation of the Carter trend, which will be drill tested this summer.
The company’s 42,960-hectare 100%-owned Patterson Lake North 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 km 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 km south of the JR zone. All three properties comprising the PLN project are accessed by provincial Highway 955.
F3 is a uranium exploration company, focusing on the high-grade JR zone and new Tetra zone discovery 13 km south in the Patterson West area on its Patterson Lake North project in the western Athabasca basin.
F3 has three properties in the Athabasca basin: Patterson Lake North, Minto and Broach. The western side of the Athabasca basin, 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.
