ARIS MINING ANNOUNCES CLOSING OF US$450 MILLION SENIOR NOTES OFFERING

TO FUND REDEMPTION OF OUTSTANDING 6.875% SENIOR NOTES

Vancouver, Canada, October 31, 2024 – Aris Mining Corporation (Aris Mining or the Company) (TSX: ARIS;

NYSE-A: ARMN) today announces that it has completed its offering of US$450 million aggregate principal

amount of 8.000% Senior Notes due 2029 (the “Notes”). Aris Mining intends to use the net proceeds from

the offering of the Notes to fund the redemption of its outstanding 6.875% Senior Notes due in 2026 on

November 20, 2024 and for working capital and general corporate purposes.

Neil Woodyer, CEO of Aris Mining, commented “We are pleased by the overwhelming investor demand for

our Note offering, which reflects confidence in our growth strategy as well as favourable conditions across

credit markets, emerging markets and gold . In response, we upsized the offering to US$450 million and

priced the new Notes at 8.00%, significantly below the indicated market range of 8. 25% to 8.5 0%. This

strategic financing repays our existing US$300 million notes, extends the maturity of our long-term debt to

October 31, 2029, while increasing our cash reserves during our transformational growth period with

ongoing expansions at both Segovia and Marmato.”

The offer and sale of the Notes will not be registered under the United States Securities Act of 1933, as amended

(the “Securities Act”), and the Notes may not be offered or sold in the United States or to U.S. persons absent

registration or an applicable exemption from the registration requirements of the Securities Act and applicable

state securities laws. This news release shall not constitute an offer to sell or the solicitation of an offer to buy

the Notes, nor shall there be any offer or sale of the Notes in any jurisdiction in which such offer, solicitation or

sale would be unlawful.
