ITAFOS PARTIALLY MONETIZES EQUITY INTEREST IN ST GEORGE MINING LIMITED

HOUSTON, TX – October 16, 2025 – Itafos Inc. (TSX-V: IFOS) (OTCQX: ITFS) (“Itafos” or “the Company”) today announces that it has

partially monetized its ownership interest in St George Mining Limited (“St George”) (ASX:SGQ) (the “Transaction”) that it acquired as

consideration for the sale of its Araxá project, announced in February of this year. Between October 13-14, 2025, Itafos sold 277,893,103

ordinary shares of St George (“SGQ Shares”) and expects to receive total gross proceeds of approximately USD$18.3MM on October 16

or 17, 2025 based on current exchange rates and before certain fees and applicable taxes. On October 16, 2025, Itafos issued an exercise

notice to exercise the 86,111,025 options at AUD$0.04 per share.

Together with the initial payment received by Itafos in February 2025 of USD$10MM (less withholding tax payable), Itafos has now

received total gross proceeds of approximately USD$28.3MM (less applicable taxes and fees) from St. George for the sale of its Araxá

project. Under the terms of the sale agreement with St George (the “Sale Agreement”), a further US$11MM is payable in two instalments.

Additionally, future value is attributable to the shares issued on exercise of the option, given the options were in the money. This financial

result demonstrates the Company’s commitment to monetize its non-core assets, strengthen its balance sheet and deliver value to

shareholders.

David Delaney, Chief Executive Officer of the Company commented, “the partial monetization of the ownership interest in St George that

we acquired from the divestiture of our Araxá rare earth project earlier this year is another indication of our intentions to deliver long-term

value to our shareholders by focusing on our core businesses. The equity interest in St George that we received as a portion of the total

consideration for the sale of Araxá had appreciated significantly since the sale closing date as St George has been able to de-risk and

advance the development of the project. As a result, we were able to recognize meaningful value from the sale of the SGQ shares at this

time.”
