EUREKA CLARIFIES UPDATE ON NUNAVIK PROJECTS

Eureka Lithium Corp. has issued this news release as the result of a review by the British Columbia Securities Commission to clarify disclosure contained in the company's news release dated March 6, 2026, which inadvertently omitted to reference one additional block of mineral claims as having lapsed. Accordingly, the company wishes to clarify that it has allowed to lapse approximately 1,094 mineral claims comprising the Raglan West project, approximately 550 mineral claims comprising the Raglan South project, approximately 1,255 mineral claims comprising the North Shore block (not previously disclosed), and approximately 1,601 mineral claims comprising the New Leaf project (collectively making up the Nunavik projects). Accordingly, at this time, the company retains approximately 158 claims (remaining claims) relating to the Nunavik projects. The company notes that the cost of renewing the lapsed mineral claims would have been approximately $680,570. The company further notes that it is actively considering whether or not to renew the remaining claims, at a cost of $26,544.

The company also notes that, as a result of the BCSC review, it has filed an amended and restated material change report in respect of the lapsed mineral claims, and that it has also filed an amended and restated management discussion and analysis for the three and nine months ended Sept. 30, 2025. Both of these documents may be obtained under the company's profile on SEDAR+.

The company recently acquired (please see news release dated Jan. 28 and Feb. 26, 2026) a 100-per-cent interest in the Cabin Lake silver-gold-zinc-lead project located in the Omineca mining district of British Columbia and a 100-per-cent interest in the Tyee titanium-vanadium project, located within the Havre-St-Pierre region of Quebec.
