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

Aris Mining Corp. is reminding holders of its Toronto Stock Exchange-listed warrants trading under the symbol ARIS.WT.A 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 $5.50 per share compared with a closing share price of $9.46 on July 8, 2025.

To date, approximately 48.2 per cent of the warrants have been exercised, generating $77-million (approximately $56-million (U.S.)) in proceeds for the company. If all remaining outstanding warrants are exercised, Aris Mining would receive an additional $83-million (approximately $61-million (U.S.)).

Neil Woodyer, chief executive officer 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, the proceeds from warrant exercises have further strengthened our balance sheet, contributing to a cash position of over $310-million (U.S.) as of June 30."

Important note for investors

Warrantholders who wish to exercise their warrants should contact their brokers or financial advisers 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.

About Aris Mining Corp.

Founded in September, 2022, Aris Mining was established with a vision to build a leading Latin America-focused gold mining company. The company's strategy blends current production and cash flow generation with transformational growth driven by expansions of its operating assets, exploration and development projects. Aris Mining is listed on the Toronto Stock Exchange and the NYSE American exchange and is led by an experienced team with a record of value creation, operational excellence, financial discipline and good corporate governance in the gold mining industry.

Aris Mining operates two underground gold mines in Colombia: the Segovia operations and the Marmato complex, which together produced 210,955 ounces of gold in 2024. With expansions under way, Aris Mining is targeting an annual production rate of more than 500,000 ounces of gold, following the Segovia mill expansion, completed in June and ramping up during the second half of 2025, and the construction of the bulk mining zone at the Marmato complex, expected to start ramping up production in the second half of 2026. In addition, Aris Mining operates the 51-per-cent-owned Soto Norte joint venture, where studies are under way on a new, smaller-scale development plan, with results expected in Q3 2025. In Guyana, Aris Mining owns the Toroparu gold/copper project, where a new preliminary economic assessment (PEA) has been commissioned and its results are also expected in Q3 2025.

Colombia is rich in high-grade gold deposits and Aris Mining is actively pursuing partnerships with the country's dynamic small-scale mining sector. With these partnerships, the company enables safe, legal and environmentally responsible operations that benefit both local communities and the industry.

Aris Mining intends to pursue acquisitions and other growth opportunities to unlock value through scale and diversification.

We seek Safe Harbor.
