ARIS MINING CLOSES ACQUISITION OF REMAINING 49% OF SOTO NORTE

Aris Mining Corp. has completed its previously announced acquisition of the remaining 49-per-cent interest in the Soto Norte joint venture in Colombia from MDC Industry Holding Company LLC (Mubadala). Aris Mining now owns 100 per cent of the Soto Norte project, and the associated precious metals stream previously granted to Mubadala has been terminated.

Neil Woodyer, chief executive officer of Aris Mining, commented: "With 100-per-cent ownership of Segovia, Marmato, Toroparu and now Soto Norte, Aris Mining is focused on building a large, diversified gold business across Colombia and Guyana. Our strategy combines strong cash flow generation from our operating mines with growth from expansions, exploration and project development.

"Since our formation in 2022, we have progressed from a buy-and-build strategy to focusing on building the high-quality assets we now own. Fewer than 15 gold companies worldwide produce more than one million ounces annually; and, with our current asset base and growth projects, Aris Mining has a clear path to join that group."

About Aris Mining Corp.

Founded in September, 2022, Aris Mining was established with a vision to build a leading South 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 intends to unlock value through scale and diversification. The company is listed on the Toronto Stock Exchange (symbol: ARIS) and the NYSE American exchange (symbol: ARMN) 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, driven by the commissioning of a second mill at Segovia, completed in June and ramping up during the second half of 2025, and the construction of the bulk-mining zone at the Marmato complex, with first gold expected in the second half of 2026.

In Guyana, Aris Mining owns the Toroparu gold project, where a new preliminary economic assessment has been completed and a prefeasibility study is in progress. Following completion of the PFS, Toroparu will be positioned to advance toward construction.

Aris Mining also owns the Soto Norte gold project, where a prefeasibility study has been completed on a smaller-scale development plan, confirming Soto Norte as a high-grade, long-life project with strong economics and industry-leading environmental and social design features. Environmental studies are being finalized, which are scheduled to be submitted in the first half of 2026 to initiate the licensing process.

We seek Safe Harbor.
