Mako Mining Announces Amended and Restated Definitive Agreements for Restructure of Mt. Hamilton Acquisition Consideration and Filing of Supplement to Management Information Circular

VANCOUVER, BRITISH COLUMBIA / ACCESS Newswire / February 18, 2026 / Mako Mining Corp. ("Mako" or the "Company") (TSXV:MKO)(OTCQX:MAKOF) announces that, in connection with its previously announced acquisition (the "Mt. Hamilton Acquisition")of 100% of the membership interests of Mt. Hamilton LLC, the owner of the Mt. Hamilton project in Nevada, USA (the "Mt. Hamilton Project"), from Sailfish Royalty Corp. ("Sailfish) (see Mako news releases dated September 30, 2025 and November 26, 2025), effective as of today's date, the parties have entered into an amendment and restatement (the "Amended Purchase Agreement") of the purchase and sale agreement of November 26, 2025, an amendment and restatement (the "Amended Gold Purchase Agreement") of the gold purchase agreement dated November 26, 2025, and a termination (the "Royalty Termination Agreement") of the royalty agreement (the "Royalty Agreement") dated November 26, 2025 proposing the grant of a 2% net smelter returns royalty (the "Royalty") on the Mt. Hamilton Project to Sailfish. The amendments have been made in order to preserve maximum flexibility for Mako to develop the Mt. Hamilton Project and derisk the impact of encumbrances over potential future development scenarios more broadly (see Mako news release dated January 9, 2026).

Mt. Hamilton Acquisition

As further described in the management information circular of Mako dated December 23, 2025 (the "Circular") previously mailed to shareholders, the transfer of beneficial ownership and control of the Mt. Hamilton Project from Sailfish to Mako US Corp. ("Mako US") was effected concurrent with the closing of Sailfish's acquisition of 100% of the membership interests of Mt. Hamilton LLC from previous owner Mt. Hamilton Holding LLC on November 26, 2025. Concurrently, the Company, Mako US and Sailfish entered into the original purchase and sale agreement, the original gold purchase agreement and the Royalty Agreement (the "First Closing Date"), and Sailfish assigned and transferred to Mako US beneficial ownership of the membership interests in Mt. Hamilton LLC and control of the Mt. Hamilton Project effective November 26, 2025. During the interim period of time between the First Closing Date and the anticipated completion of the transfer of the registered legal ownership of the membership interests by Sailfish to Mako US (the "Closing"), following and subject to receipt of all applicable shareholder approvals and final approval of the TSX Venture Exchange ("TSXV") by each of Mako and Sailfish, Sailfish has agreed to hold the legal registered ownership of the Mt. Hamilton Project as nominee, agent and bare trustee for and on behalf of Mako US. The outside date for Closing is March 16, 2026, or such other date as may be agreed in writing by the parties.

Amended Purchase Agreement

The Amended Purchase Agreement reflects the elimination of the proposed grant of the Royalty on the Mt. Hamilton Project to Sailfish, and the removal of the Mt. Hamilton Project from the secured corporate level gold stream proposed to be granted to Sailfish, subject to and conditional on Closing, and, in lieu of the elimination of the Royalty, proposes the grant of an additional secured corporate level gold steam for a term of 72 months following the initial 60-month gold stream under the terms of the Amended Gold Purchase Agreement, as further detailed below. No substantive changes have been made to the representations, warranties, covenants, termination provisions and fallback sale provisions contemplated under the original purchase and sale agreement other than in relation to removing the Royalty.

Amended Gold Purchase Agreement

As contemplated under the original gold purchase agreement, the Amended Gold Purchase Agreement proposes that the Company will agree to sell to Sailfish an amount of refined gold, from any of its projects, other than the Mt. Hamilton Project, during the initial 60-month stream term (the "Initial Stream Term"), equal to 341.7 troy ounces per month, subject to adjustment to ensure that the amount of refined gold per month will not be (the "Adjustment Formula"): (i) less than the equivalent of US$738,000 (after deduction of the acquisition price paid by Sailfish to the Company in accordance with the stream gold price), which is equivalent to US$2,700/oz Refined Gold; and (ii) more than the equivalent of US$1,011,333.33 (after deduction of the acquisition price paid by Sailfish to the Company in accordance with the stream gold price), which is equivalent to US$3,700/oz refined gold free and clear of any and all encumbrances. The amount of payable gold for each monthly delivery during the Initial Steam Term will be adjusted upward or downward based on the application of the Adjustment Formula.

The Amended Gold Purchase Agreement also provides for an additional gold stream for a term of 72 months (the "Additional Stream Term"), during which the Company proposes to sell to Sailfish an amount of refined gold from any of its projects, other than the Mt. Hamilton Project, equal to 100 troy ounces per month, not subject to the Adjustment Formula, free and clear of any and all encumbrances.

As contemplated under the original gold purchase agreement, for each ounce of deliverable gold, Sailfish will pay to the Company 20% of the London p.m. fixed price for refined gold in United States dollars, as determined by the London Bullion Market Association (or any successor association or body) on the date of delivery of such deliverable gold. Mako also continues to have the right to source monthly mineral deliveries under each stream by way of the purchase of gold credits or by way of the delivery of gold equivalent ounces.

The obligations under the Amended Gold Purchase Agreement will take effect and commence upon and subject to Closing, at which time the Initial Stream Term will commence, and the Additional Stream Term will not commence until following satisfaction of the Initial Stream Term.

The amended stream will be secured against all present and after-acquired property of Mako, in addition to specific guarantees and pledges relating to an encumbrance by Sailfish over the Mt. Hamilton Project. The deemed purchase price of the amended gold stream is US$40 million (comprised of US$33 million for the Initial Stream Term and US$7 million for the Additional Stream Term), with such deemed purchase price satisfied through the transfer of legal title to Mt. Hamilton LLC from Sailfish to Mako.

If Closing does not occur, the Amended Gold Purchase Agreement shall terminate ab initio and the secured gold stream will never come into force or effect.

Board Recommendation

The Board of Directors of Mako, acting on the unanimous recommendation of the Special Committee of the Board, has unanimously determined (with Messrs. Leisman, Lalani and Jacobi abstaining from voting) that the Mt. Hamilton Acquisition, as amended by the terms of the Amended Purchase Agreement and the Amended Gold Purchase Agreement, is in the best interests of Mako.
