Foremost Announces Formation of GR and Blackwing Joint Ventures and Issuance of Warrants to Denison at a Significant Premium

(NASDAQ: FMST) (CSE: FAT) Foremost Clean Energy Ltd. has closed a transaction with Denison Mines Corp. involving the sale of a 31% interest in the GR and Blackwing properties, the formation of two exploration joint ventures, and the issuance of 1,031,191 share purchase warrants to Denison in exchange for total cash consideration of $650,000. The warrants have an exercise price of $1.80 per share, representing over a 175% premium to Foremost’s closing share price of $0.64 on October 22, 2026, and have a 5-year term. Foremost and Denison have formed two exploration joint ventures, with Foremost holding a 20% ownership interest in each of the GR and Blackwing properties. The GR property consists of 16 mineral claims covering 78,585 hectares, and the Blackwing property consists of 3 mineral claims covering 12,627 hectares. Denison is responsible for funding its 80% share of future expenditures and has committed to either carry out geophysical studies or make deficiency deposits to maintain the properties until at least January 4, 2028. Foremost expects Denison will carry out geophysical studies within the next 12 months to further define the exploration potential of the properties and generate future drill targets. Foremost has the option, within 6 months of the earlier of the completion of the initial geophysical surveys or the date of the last of the initial expenditures, to either fund its share of the initial expenditures or dilute its ownership pursuant to the terms of the joint ventures. The number of warrants exercisable by Denison at any time is limited so that Denison’s ownership of Foremost does not exceed 19.95%. At maturity, if exercise of any remaining warrants would result in Denison exceeding the 19.95% ownership cap, Foremost will either apply for and obtain an extension of the warrant term as approved by the Canadian Securities Exchange or purchase from Denison any remaining warrants not exercisable due to the ownership cap based on the differential between the exercise price and the current market price. The warrants are subject to a four-month hold period expiring on March 3, 2027, after which they will be transferable. The Option Agreement between Denison and Foremost dated September 23, 2024, originally covering 10 properties, has been amended and restated to exclude the GR and Blackwing properties, so Foremost no longer has any right to increase its ownership interest in those two properties. The amended and restated Option Agreement preserves Foremost’s right to complete Option Tranche 3 and earn an additional 19% interest (for an aggregate interest of 70%) in 7 of the remaining 8 properties under option from Denison and a minimum 51% interest in Hatchet Lake, by completing $12.0 million in eligible exploration expenditures on the remaining 8 properties by July 9, 2029, and paying Denison $2.5 million in additional consideration in cash, common shares, or a combination thereof. The amended and restated investor rights agreement between Denison and Foremost dated July 23, 2025, was further amended for housekeeping or administrative purposes. Immediately prior to the transaction, Denison owned or controlled 3,448,610 common shares of Foremost (approximately 19.9% of issued and outstanding shares) and held 607,600 share purchase warrants (approximately 15.2% of outstanding warrants). As a result of the acquisition of the new warrants, Denison now holds 1,638,791 share purchase warrants (approximately 32.6% of outstanding warrants) and continues to own 3,448,610 common shares (19.9%). The warrants are subject to a restriction that Denison shall not be entitled to exercise any warrants to the extent that, after such exercise, Denison would own or control more than 19.95% of Foremost shares. The early warning report required by National Instrument 62-104 will be filed on SEDAR+ in connection with this transaction. The technical content of the news release was reviewed and approved by Cameron MacKay, P. Geo., Vice President of Exploration for Foremost Clean Energy Ltd.

Foremost Clean Energy Announces Commencement of Inaugural Drill Program at the Turkey Lake Property

(NASDAQ:FMST) (CSE:FAT) (TSX:DML) Foremost Clean Energy Ltd. has commenced its first diamond drill program on the Turkey Lake Uranium Project in northern Saskatchewan. The drill program is designed to test priority targets identified by integrating a ground gravity survey completed in January 2026 with historical drilling, electromagnetic, magnetic, and geological data. The Turkey Lake property features more than 10 kilometres of underexplored conductive strike length, with priority targets refined by the recent gravity survey. The planned drill program will consist of 1,000 metres of drilling to test approximately four target areas. Historical drilling on the property identified uranium mineralization, including 0.16% U₃O₈ over 0.6 metres in hole TUR-4 and 0.12% U₃O₈ over 0.5 metres in hole TL-10-13, as well as elevated radioactivity in nearby follow-up drilling. The property is located along the northeastern margin of Saskatchewan's Athabasca Basin, approximately 23 kilometres north of the McClean Lake Mill and 25 kilometres north of the Eagle Point Mine. The sandstone cover on the property is less than 50 metres thick, allowing for shallow drilling to test both unconformity-related and basement-hosted uranium mineralization. The ground gravity survey identified multiple gravity low anomalies, interpreted as possible zones of hydrothermal alteration and potential fluid pathways, several of which coincide with electromagnetic conductors and magnetic features. The top targets from the gravity survey have been grouped into Basin Edge Targets (potential for unconformity-hosted mineralization) and BEX Targets (potential for basement-hosted mineralization). Foremost Clean Energy Ltd. holds a portfolio of 10 property interests spanning over 330,000 acres in the Athabasca Basin region. Upon completion of a transaction announced on October 22, 2026, Foremost will hold an option from Denison Mines Corp. to increase its interest to up to 70% in eight uranium properties (excluding Hatchet Lake, where Foremost can earn up to 51%), and a 20% ownership interest in the GR and Blackwing joint ventures with Denison. The company also has lithium-focused projects covering over 43,000 acres in Manitoba. Cameron MacKay, P.Geo., Vice President of Exploration, is the Qualified Person for the technical content of this release. David Cates is listed as Interim CEO.

Foremost Reports Assay Results from Tuning Fork Uranium Zone Including High-Grade Highlight of 1.3% U₃O₈ over 1.0 Metre

(NASDAQ:FMST) (CSE:FAT) (TSX:DML) Foremost Clean Energy Ltd. announced chemical assay results from its 2026 drilling program at the Hatchet Lake South Uranium Project (“Hatchet Lake”) in northern Saskatchewan. The 2026 drill program identified uranium mineralization above a cut-off grade of 0.05% U₃O₈ in eight drill holes across multiple drill fences spanning 200 metres of strike length at the Tuning Fork Uranium Zone (“TFUZ”). Drill hole TF-26-30 returned a high-grade intercept of 1.3% U₃O₈ over 1.0 metre, including a subinterval of 4.5% U₃O₈ over 0.25 metres, within a broader interval of 0.36% U₃O₈ over 4.0 metres from 139.9 to 143.9 metres. The 2026 Hatchet Lake program comprised 19 diamond drill holes totaling 3,848 metres, testing five drill fences spaced approximately 50 metres apart along 200 metres of strike at the TFUZ. Eight holes intersected uranium mineralization across four of these fences. Other notable results include TF-26-36, which returned 0.19% U₃O₈ over 2.8 metres on the northernmost drill fence, and TF-26-35A, which returned 0.25% U₃O₈ over 0.25 metres. The mineralized trend remains open to the north (approximately 250 metres) and south (approximately 600 metres), with follow-up drilling expected to prioritize extensions in both directions, especially to the south. Sampling and analysis were conducted by the Saskatchewan Research Council (SRC) Geoanalytical Laboratories, with control samples included at a frequency of approximately 5%. Downhole radioactivity was measured using a Mount Sopris QL40-GR Natural Gamma probe, calibrated on July 17, 2025 at the Grand Junction, Colorado calibration test pits, and measurements were collected at 0.10-metre intervals. The company’s portfolio includes 10 property interests spanning over 330,000 acres in the Athabasca Basin region of northern Saskatchewan. Upon completion of a transaction announced on October 22, 2026, Foremost will hold an option from Denison Mines Corp. to increase its interest to up to 70% in eight uranium properties (other than Hatchet Lake, in which Foremost can earn up to 51%), and a 20% ownership interest in the GR and Blackwing joint ventures with Denison. Foremost also has lithium-focused projects spanning 43,000+ acres in Manitoba. The technical content of the release was reviewed and approved by Cameron MacKay, P.

Foremost to Form Joint Ventures with Denison for GR and Blackwing Properties and to Issue Warrants at a Significant Premium

(NASDAQ: FMST) (CSE: FAT) Foremost Clean Energy Ltd. has entered into an agreement with Denison Mines Corp. to sell a 31% interest in the GR and Blackwing properties, form two exploration joint ventures, and issue 1,031,191 share purchase warrants in exchange for total consideration of $650,000. The warrants will have an exercise price of $1.80 per share, representing over a 175% premium to Foremost’s closing share price of $0.64 on October 22, 2026, and will have a 5-year term. Completion of the transaction is expected on or about November 2, 2026, subject to regulatory and stock exchange approvals and other customary closing conditions. Upon closing, Foremost and Denison will form two exploration joint ventures, with Foremost retaining a 20% ownership interest in each property. The GR property consists of 16 mineral claims covering 78,585 hectares, and the Blackwing property consists of 3 mineral claims covering 12,627 hectares. Denison will fund 80% of future expenditures under the JV agreements and is committed to either carry out geophysical studies or make deficiency deposits to maintain the properties until at least January 4, 2028. Foremost retains an option to decide within 6 months of the earlier of completion of the initial geophysical surveys or the date of the last of the Initial Expenditures whether to fund its share or dilute its ownership. The number of warrants exercisable by Denison at any time is limited so that Denison’s ownership of Foremost does not exceed 19.95%. At maturity, if exercising remaining warrants would exceed this cap, Foremost will either seek an extension of the warrant term or purchase the remaining warrants based on the price differential. The warrants will be subject to a four-month hold period and will then be transferable. The Option Agreement between Denison and Foremost dated September 23, 2024, covering 10 properties, will be amended and restated to exclude the GR and Blackwing properties, so Foremost will no longer have rights to increase its ownership in those two properties. Foremost retains the right to complete Option Tranche 3 and earn an additional 19% interest (for a total of 70%) in 7 of the remaining 8 properties and a minimum 51% interest in Hatchet Lake by completing $12.0 million in eligible exploration expenditures by July 9, 2029, and paying Denison $2.5 million in cash or shares.

RedChip has also secured a two-week national television campaign for Foremost, featuring a 30-second advertisement on CNBC, Fox Business, Bloomberg TV, and other platforms, scheduled for the second half of October at a cost of USD$150,000. No securities will be issued to RedChip as compensation, and RedChip maintains an arm's-length relationship with Foremost. Foremost received a notification letter from Nasdaq indicating non-compliance with Listing Rule 5550(a)(2), as its shares closed below US$1.00 for 30 consecutive business days from September 4, 2026, to October 16, 2026. Foremost has a 180-calendar day compliance period ending April 19, 2027, to regain compliance by having its closing bid price meet or exceed US$1.00 for at least ten consecutive business days. If compliance is not regained by April 17, 2027, Foremost may be eligible for an additional 180-day grace period if it meets other listing requirements. Management is evaluating options to address the bid price deficiency and remains committed to maintaining the Nasdaq listing.
