THIS NEWS RELEASE IS NOT FOR DISTRIBUTION TO U.S. NEWSWIRE SERVICES FOR DISSEMINATION IN THE UNITED STATES.

Cartier Resources Inc. (TSX-V: ECR) (" Cartier " or the " Corporation ") announces the execution, on March 31, 2025, of an amending agreement (the " Amending Agreement ") further to the engagement letter dated March 20, 2025 between Paradigm Capital Inc. (the " Agent ") and the Corporation (the " Engagement Letter ") with respect to its previously announced "best efforts" private placement offering of securities of Cartier (the " Offering ").

The Amending Agreement was concluded to address potential impacts of several tax measures unveiled on March 25, 2025 by the Minister of Finance (Québec) in connection with his 2025-2026 budget (the " 2025 Québec Budget ").

The Offering will continue to raise aggregate gross proceeds for the Corporation of up to approximately $7,300,160 (subject to a potential increase thereof for additional gross proceeds of up to $1,095,024 in accordance with the exercise of the Agent's Option, as further described below).

The Offering remains a combination of: (a) units of the Corporation issued on a charitable flow-through basis that will qualify as "flow-through shares" within the meaning of subsection 66(15) of the Income Tax Act (Canada) (the " Tax Act ") and section 359.1 of the Québec Tax Act (the " Premium FT Units ") for gross proceeds of approximately $5,000,200; and (b) units of the Corporation (the " Hard Dollar Units ") and, together with the Premium FT Units, the " Offered Securities ") at $0.13 per Hard Dollar Unit for gross proceeds of $2,299,960. Each Premium FT Unit consists of one common share in the capital of the Corporation (each a " Common Share ") and one common share purchase warrant (each a " Premium FT Warrant "), with each such Common Share and Premium FT Warrant qualifying as a "flow-through share" within the meaning of subsection 66(15) of the Tax Act and section 359.1 of the Québec Tax Act. Each Hard Dollar Unit consists of one Common Share of the Corporation and one common share purchase warrant (each a " Hard Dollar Warrant "), and for certainty, each such Common Share and Hard Dollar Warrant will not qualify as a "flow-through share".

Under the Engagement Letter, the subscription price of the Premium FT Units (the " FT Subscription Price ") was set on March 20, 2025 at $0.23 per FT Unit, based on certain tax benefits then available under the Quebec Tax Act and the Tax Act, including, but not limited to, the Québec Capital Gain Exemption and Québec Additional Deductions (each as defined herein).

The 2025 Québec Budget introduced major changes to the flow-through share regime under the Taxation Act (Québec) (the " Québec Tax Act "), including the following measures (collectively, the " 2025 Québec Budget Amendments "):

However, the 2025 Québec Budget provides that the abolition of the Québec Additional Deductions will not apply to flow-through shares issued after March 25, 2025 if they are issued following a public announcement made no later than March 25, 2025 (which is the case of the Offering), provided furthermore that a report of exempt distribution is filed with the Autorité des marchés financiers no later than May 31, 2025 (the " Grandfathering Exception ").

Considering the potential impacts of the 2025 Québec Budget Amendments as announced on March 25, 2025, the Corporation, on March 31, 2025, (a) entered into the Amending Agreement; and (b) entered into a subscription and renunciation agreement with PearTree Securities Inc. (" PearTree "), on behalf of certain disclosed principals (the " Subscription and Renunciation Agreement ").

Pursuant to the Subscription and Renunciation Agreement, a mechanism was introduced to allow for the adjustment of the FT Subscription Price to $0.205 or $0.182 from $0.23 (i.e. the price initially agreed upon on March 20, 2025 under the Engagement Letter) depending on whether the Québec Capital Gain Exemption and/or Québec Additional Deductions are determined on the Closing Date (as defined herein) to be available in respect of the Offering, based on any written statements that are issued by the Minister of Finance (Québec) to clarify the scope of the 2025 Québec Budget Amendments and the Grandfathering Exception. Under the Subscription and Renunciation Agreement, corresponding adjustments would also be made to the number of Premium FT Units issued so as to retain approximately the same aggregate gross subscription proceeds.

All of the other material terms of the Offering remain unchanged, including the following:

• The gross proceeds from the sale of the Premium FT Units will be used by the Corporation to incur eligible "Canadian exploration expenses" that qualify as "flow-through mining expenditures" (as both terms are defined in the Tax Act) (the " Qualifying Expenditures ") related to the projects of the Corporation in Québec. The Qualifying Expenditures will be renounced in favour of the subscribers of the Premium FT Units with an effective date no later than December 31, 2025 and in an aggregate amount of not less than the total amount of the gross proceeds raised from the issuance of the Premium FT Units.
• Each Premium FT Warrant and Hard Dollar Warrant will entitle the holder thereof to acquire one Common Share of the Corporation (each a " Warrant Share ") on a non-flow-through basis at an exercise price of $0.18 for a period of 5 years following the Closing Date (as herein defined).
• The expiry of both the Premium FT Warrants and the Hard Dollar Warrants may be accelerated by the Corporation if the daily volume-weighted average trading price of the Common Shares on the TSX Venture Exchange (the " TSX-V ") exceeds $0.18 for a period of twenty (20) consecutive trading days, at any time during the period: (i) beginning on the date that is three (3) years from the Closing Date (as herein defined); and (ii) ending on the date the Premium FT Warrants and the Hard Dollar Warrants expire (the " Acceleration Trigger "). Following an Acceleration Trigger, the Corporation may give notice in writing (the " Acceleration Notice ") to the holders of the Premium FT Warrants and the Hard Dollar Warrants that such warrants will expire thirty (30) days following the date on which the Acceleration Notice is given.
• The Corporation will grant the Agent an option (the " Agent's Option "), exercisable up to 48 hours prior to the Closing Date (as herein defined), to sell that number of Offered Securities for additional gross proceeds of up to $1,095,024.

The Offering is being made by way of private placement in Canada. The Offered Securities will be subject to a four month and one day hold period under applicable securities laws in Canada. The Offering is expected to close on or about April 14, 2025 (the " Closing Date "), subject to the satisfaction or waiver of customary closing conditions, including the conditional listing approval of the TSX-V.
