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

VANCOUVER, BC, July 9, 2025 /PRNewswire/ – 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, the 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.

Warrant Exercise Summary

About Aris Mining

Founded in September 2022, Aris Mining was established with a vision to build a leading Latin America-focused gold mining company. Our strategy blends current production and cashflow generation with transformational growth driven by expansions of our operating assets, exploration and development projects. Aris Mining is listed on the TSX (ARIS) and the NYSE-A (ARMN) and is led by an experienced team with a track 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 underway, 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 H2 2025, and the construction of the Bulk Mining Zone at the Marmato Complex, expected to start ramping up production in H2 2026. In addition, Aris Mining operates the 51% owned Soto Norte joint venture, where studies are underway 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, we enable 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.
