Foremost Clean Energy Ltd.’s SEC filings document foreign-issuer current reports for its mineral exploration business and related capital structure. Form 6-K submissions incorporate press releases on uranium and gold-lithium exploration, including Hatchet Lake drill programs, CLK geophysical surveys, Jean Lake sampling and drilling, and exploration agreements in Manitoba.
The filing record also includes financing documents tied to a bought-deal private placement, such as an underwriting agreement, subscription agreement and warrant indenture, and references a Form F-3 registration statement. These disclosures cover flow-through units, common share purchase warrants, project updates, formal exhibits, and capital-raising terms.
Foremost Clean Energy Ltd. provided an exploration update on its 25,753-acre CLK Uranium Property in Saskatchewan’s Athabasca Basin. A 2025 helicopter-borne MobileMT electromagnetic and magnetic survey covering 808 line-kilometres mapped conductive and resistive features tied to structures prospective for unconformity-style uranium mineralization.
The company then completed an ambient noise tomography survey using 221 sensors over roughly 7.5 × 3.8 km to image subsurface shear-wave velocities to about 2 km depth. These datasets are being integrated to define high-priority drill targets near historic hole CLG-D1, which intersected 8,600 ppm U (approx. 1.01% U3O8), and CLG-D5, which intersected 510 ppm U (approx. 0.06% U3O8). Historical uranium values are based on legacy XRF data and are not compliant with current standards.
The CLK Property is fully permitted for a multi-phase exploration program including up to 30 diamond drill holes, and the technical content was reviewed by a Qualified Person under National Instrument 43-101.
Foremost Clean Energy Ltd. reported new uranium exploration results from its 2026 drill program at the Hatchet Lake South Project in Saskatchewan’s Athabasca Basin. Drilling at the newly named Tuning Fork Uranium Zone has expanded mineralization to over 150 metres of strike length stepping out from the 2025 discovery hole.
Ten diamond drill holes totaling 2,113 metres have been completed so far, with five intersecting unconformity-related uranium mineralization above the company’s 0.05% eU₃O₈ reporting threshold. The best interval is 0.34% eU₃O₈ over 4.6 metres in hole TF-26-30, including 1.0% eU₃O₈ over 1.4 metres.
Management highlights consistent uranium mineralization and hydrothermal alteration at the Athabasca unconformity across three drill fences and plans further drilling to extend the zone northward and refine the geometry while also advancing additional high-priority targets on the broader Hatchet Lake Project.
Foremost Clean Energy Ltd. entered into a bought-deal underwriting for 1,618,000 flow-through units at $3.40 per unit, raising gross proceeds of $5,501,200. Each unit includes one flow-through common share and half a warrant, with each whole warrant exercisable at $4.40 for 24 months after closing.
The company granted the underwriter an option to sell up to an additional 242,700 units at the same price for potential extra proceeds of $825,180. Proceeds are to fund qualifying exploration programs in Saskatchewan and Manitoba, with associated tax benefits renounced to Canadian investors under Canada’s flow-through share rules.
Foremost Clean Energy Ltd. completed a bought deal private placement of flow-through units, raising aggregate gross proceeds of C$5,746,680. The company issued 1,690,200 flow-through units at C$3.40 per unit, each including one flow-through share and half a warrant.
Each whole warrant allows investors to buy one common share at C$4.40 until March 31, 2028. Certain directors subscribed for 63,000 units. Foremost plans to use an amount equal to the gross proceeds on qualifying Canadian exploration expenses in Saskatchewan and Manitoba and renounce these tax benefits effective December 31, 2026.
Foremost Clean Energy Ltd. filed a report highlighting an upcoming live investor webinar on March 18, 2026 at 4:15 p.m. ET, hosted by RedChip Companies. President and CEO Jason Barnard will present an overview of the Company’s uranium exploration portfolio in Saskatchewan’s Athabasca Basin and plans to advance high-priority drill targets.
The webinar will cover Foremost’s option agreement with Denison Mines Corp., under which it may earn up to a 70% interest in 10 uranium properties spanning over 330,000 acres, plus 51% at Hatchet Lake. The Company will also discuss its 2026 exploration objectives and its additional lithium projects across more than 55,000 acres in Manitoba and Quebec.
Foremost Clean Energy Ltd. has started its planned ~5,000-metre 2026 winter diamond drill program at the Hatchet Lake Uranium Project in the eastern Athabasca Basin of Saskatchewan. Drilling is underway at the Tuning Fork target, following a 2025 uranium discovery that intersected 0.87% U₃O₈ over 0.45 metres within a broader 6.2-metre interval averaging 0.10% U₃O₈ at the Athabasca unconformity.
The current program aims to test along-strike and down-dip continuity of this mineralization, refine structural controls on uranium emplacement, and assess additional targets at Hatchet Lake South and North, including the Beta Grid and Richardson SE areas. Foremost views Hatchet Lake as a strong platform for further unconformity-related uranium discoveries within the region.
Foremost Clean Energy Ltd. filed a Form 6-K after signing an Exploration Agreement with Kiciwapa Cree Nation in Manitoba. The Agreement, dated February 24, 2026, sets a formal framework for mineral exploration within Kiciwapa Cree Nation’s Traditional and Ancestral Territory.
The parties commit to transparency, regular communication, environmental and cultural stewardship, and meaningful community engagement. The Agreement includes opportunities for Kiciwapa Cree Nation to participate in environmental and cultural monitoring, as well as employment, training, contracting opportunities, and financial commitments supporting community engagement, capacity initiatives, and an Economic Development Fund.
Foremost Clean Energy Ltd. reported new gold assay results from a targeted historic core resampling program at its 100%-owned Jean Lake Gold-Lithium Property in Manitoba. Resampling of previously unassayed 2023 drill core along the Valkyrie and Midas trends identified additional mineralized intervals, including 1.10 g/t gold over 8.0 metres in hole FM23-25 from 22.0–30.0 metres and 0.64 g/t gold over 10.4 metres in hole FM23-08 from 106.5–116.9 metres.
The company combined these new assays with its 2023 drill data to better define gold distribution and refine its structural model along the Valkyrie Trend, which has now been traced over roughly 600 metres of strike. These results will guide the next phase of exploration, expected to include step-out and infill drilling to test continuity and expand the mineralized footprint.
Foremost Clean Energy filed a Form 6-K to share final results from its 2025 diamond drill program at the 100%-owned Jean Lake Gold-Lithium Property in Manitoba. The 15-hole, 2,266-metre program outlined an emerging gold corridor along the Valkyrie Trend.
Key near-surface intercepts include 9.4 g/t Au over 2.2 metres from 48.0 metres, including 27.9 g/t Au over 0.7 metres in hole JL25-010, and 6.2 g/t Au over 2.6 metres from 52.5 metres, including 31.1 g/t Au over 0.5 metres in JL25-009. Multiple holes show broader 1–3 g/t envelopes hosting higher-grade zones exceeding 20–80 g/t Au.
Gold mineralization has now been intersected along roughly 600 metres of strike length, interpreted within a steeply dipping shear zone that remains open along strike and at depth. Foremost plans follow-up step-out and infill drilling to extend the corridor and better target higher-grade zones, supported by detailed QA/QC procedures and review by a qualified person under NI 43-101.
Foremost Clean Energy Ltd. filed a Form 6-K with unaudited results for the nine months ended December 31, 2025, showing a net loss of $4.17 million and negative operating cash flow of $6.13 million. Cash declined to $4.08 million from $5.01 million as the company funded intensive exploration.
Total assets rose to $35.94 million, driven by $29.08 million in exploration and evaluation assets and new marketable securities from the Rio Grande spin-out. Liabilities fell to $1.48 million after repaying term loans, leaving equity at $34.46 million. The company discloses “material uncertainties” that cast substantial doubt on its ability to continue as a going concern, relying on continued equity and debt financing. It advanced its Athabasca uranium option with Denison and Manitoba/Quebec lithium projects, and recognized a $1.79 million recovery of flow-through premium liability tied to completed qualifying exploration spend.
