ARIS MINING REMINDS ARIS.WT.A WARRANT HOLDERS OF UPCOMING EXPIRY

Vancouver, Canada, July 9, 2025 – Aris Mining Corporation (Aris Mining or the Company) (TSX: ARIS; NYSE-A: ARMN)

reminds holders of its TSX-listed warrants trading under the symbol ARIS.WT.A (the Warrants) that the Warrants will

automatically expire at the close of markets on July 29, 2025. Any Warrants not exercised by that time will become

void and have no value.

The Warrants are currently “in-the-money”, with an effective exercise price of C$5.50 per share1 compared to a

closing share price of C$9.46 on July 8, 2025.

To date, approximately 48.2% of the Warrants have been exercised, generating C$77.0 million (approximately US$56

million) in proceeds for the Company. If all remaining outstanding Warrants are exercised, Aris Mining would receive

an additional C$83.0 million (approximately US$61 million).

Neil Woodyer, CEO of Aris Mining, commented “The upcoming expiry of the Warrants represents the final step in

simplifying our capital structure. Since our formation in September 2022, we have progressively eliminated legacy

convertible instruments, resulting in a more streamlined share structure with no overhangs. Combined with strong

cash flow from operations, t he proceeds from warrant exercises have further strengthened our balance sheet,

contributing to a cash position of over US$310 million as of June 30."

Important Note for Investors

Warrant holders who wish to exercise their Warrants should contact their brokers or financial advisors to ensure

sufficient time is allowed to complete the process. Please note that brokerage firms may impose earlier cut-off times

for exercise instructions, and holders should confirm the deadline applicable to their accounts.
