Laurian Announces Proposed Private Placement of Flow-through Units

Press Release

TORONTO, ONTARIO (December 17, 2025) – LAURION Mineral Exploration Inc. (TSX.V: LME|OTC: LMEFF|FSE: 5YD) (“LAURION” or the “Corporation”) today announced that it is proposing to complete a flow-through private placement on a non-brokered basis (the “Private Placement”). The Corporation intends to raise up to approximately $1.6 million in gross proceeds by issuing up to approximately 4,848,485 “flow through” units (“FT Units”) at a price of $0.33 per FT Unit.

Each FT Unit will consist of one common share of the Corporation to be issued as a “flow-through share” (as defined in subsection 66(15) of the Income Tax Act (Canada) (the “Tax Act”)) and one-half of one common share purchase warrant (each whole warrant, a “Warrant”). Each Warrant will entitle the holder thereof to acquire one non flow-through common share of the Corporation at a price of $0.39 per share for a period of 24 months from the date of issuance.

The gross proceeds raised from the FT Units will be used to incur eligible “Canadian exploration expenses” (“CEE”) at the Corporation’s flagship Ishkõday Project that qualify as “flow-through mining expenditures”, as such terms are defined in the Tax Act. LAURION intends to allocate the proceeds from the Private Placement to advance the Corporation’s 2026 drill program on the Ishkõday property, focusing on the gold and base metal A-Zone to the McLeod and CRK corridor (approximately 1.9 km strike) and the proximal orogenic Sturgeon River Mine area, located within the 6.0 x 2.5 km mineralized corridor. The program will include systematic in-fill and step-out drilling to define continuity of known mineralized envelopes and test depth and strike extensions where mineralization converges. LAURION’s exploration strategy aims to build resource potential within the A-Zone and Sturgeon River Mine corridors.

The closing of the Private Placement, as well as the payment of any finders’ fees in connection therewith, are subject to the approval of the TSX Venture Exchange (the “TSXV”). The Corporation intends to close the Private Placement on or about December 19, 2025, subject to receipt of all necessary regulatory approvals. In connection with the Private Placement, the Corporation may pay finders’ fees. All securities issued pursuant to the Private Placement will be subject to, among other things, a hold period of four months and one day in accordance with applicable Canadian securities laws.
