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.
Foremost Clean Energy Ltd. is launching a 5,000-metre diamond drill program at its Hatchet Lake Uranium Project in northern Saskatchewan, anticipated to begin in mid February. The work follows a 2025 winter campaign that delivered a new uranium discovery at the Tuning Fork target area.
The discovery hole TF-25-16 intersected 0.87% U₃O₈ over 0.45 metres within a broader 6.2-metre interval averaging 0.10% U₃O₈ at the Athabasca unconformity. The 2026 program will step out around this hole and test additional high-priority targets at Tuning Fork, the Beta Grid, and the Richardson SE area, using historic Denison data and new geophysical modelling to refine drill targeting.
Foremost Clean Energy Ltd. reported that it has engaged RedChip Companies to lead its investor relations and strategic communications. RedChip will use digital distribution, webinars, roadshows, and its television program to present Foremost’s uranium and lithium exploration story to institutional and retail investors.
Foremost is advancing multiple drill programs in Canada’s Athabasca Basin under an option to earn up to 70% interest in 10 uranium properties from Denison Mines, alongside lithium projects in Manitoba and Quebec. Under the agreement, RedChip will receive $11,000 per month for six months, starting January 19, 2026, with no securities issued as compensation, and the engagement remains subject to Canadian Securities Exchange approval.
Foremost Clean Energy Ltd. filed a Form 6-K to furnish a press release on new exploration results at its 100%-owned Jean Lake Gold–Lithium Project in Manitoba. The company reports positive lithium assays from drill hole JL25-005B in the B1 pegmatite, including 1.64% Li₂O over 5.0 metres and 1.46% Li₂O over 4.8 metres, with higher-grade internal intervals up to 2.80% Li₂O. These lithium intercepts complement previously reported gold results, supporting Jean Lake as a multi-commodity target.
The company has completed a historic core re-sampling program at Jean Lake and is awaiting additional assays to refine its geological and structural model. Management also highlights plans for an upcoming drill program at the Hatchet Lake Uranium Property in Saskatchewan’s Athabasca Basin, aligning with its focus on uranium and lithium exploration to support long-term clean energy demand.
