ARIS MINING AND THE GOVERNMENT OF COLOMBIA REACH LONG-TERM AGREEMENT FOCUSED ON SECURITY AND SUSTAINABILITY TO END ICSID ARBITRATION

Aris Mining Corp. has entered into a settlement and termination agreement with the Republic of Colombia, represented by the National Agency for Legal Defense of the State (ANDJE), to end the arbitration proceeding brought under the Canada-Colombia free trade agreement (ICSID case No. ARB/18/23).

The arbitration was originally initiated in May, 2018, by Gran Colombia Gold Corp. (renamed GCM Mining) before the International Centre for Settlement of Investment Disputes (ICSID), an institution of the World Bank Group, and included a request for a cash award for alleged damages. Following Aris Mining's formation through the merger of GCM Mining and Aris Gold in September, 2022, Aris Mining continued the process but engaged with the government of Colombia to pursue a constructive, co-operative solution.

Neil Woodyer, chief executive officer of Aris Mining, commented: "We are very pleased to have resolved this complex matter through discussion and co-operation rather than arbitration. By electing not to continue the legacy cash claim from 2018 and with both parties agreeing to suspend the arbitration process to explore constructive solutions, this settlement reflects the success of a collaborative approach. Importantly, this is the first agreement of its kind in Colombia to resolve an investor-state arbitration. It demonstrates our shared commitment with the government of Colombia to work together to enhance security, promote responsible mining practices and support sustainable development in the communities where we operate. Aris Mining appreciates the constructive engagement of ANDJE and the government entities that participated in these discussions."

Key elements of the settlement:

• The parties have terminated the ICSID arbitration and settled the claims submitted to this case.
• No cash payments were required or contemplated as part of the settlement, reflecting an agreement structured on the exchange of performance obligations rather than financial consideration.
• The material terms of settlement are:
  • The entry into three pillar agreements that include performance obligations on the part of each of Aris Mining, the Republic of Colombia and relevant Colombian regulatory agencies in respect of formalization in the Marmato area, and collaborative initiatives with the National Police and Ministry of Defence;
  • Engagement with the Attorney General's Office to support continuing legal and enforcement processes that protect the company's operations and work force;
  • Co-operation commitments from CORPOCALDAS, the Caldas regional environmental authority for Marmato, to oversee compliance of formalized mining operations in the Cerro El Burro area with applicable mining regulations and permits, and to exercise its enforcement powers, including imposing fines, sanctions and precautionary measures where necessary;
  • Each party assuming responsibility for their own costs associated with the arbitration and its settlement.
• The pillar agreements, jointly developed by Aris Mining, and the government of Colombia are:
  1. Agreement for mining formalization and sustainable territorial development in the Marmato area with the Ministry of Mines and Energy and the National Mining Agency;
  2. Collaboration and co-operation agreement with the National Police;
  3. Collaboration agreement with the Ministry of Defense.

The settlement agreement and associated pillar agreements will remain in effect for a 10-year term and will be overseen by a joint representatives committee comprising delegates from Aris Mining and ANDJE to ensure effective implementation.

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 TSX (ARIS) and the NYSE-A (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 H2 (second half) 2025, and the construction of the bulk mining zone at the Marmato complex, with first gold expected in H2 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 holds a 51-per-cent interest in the Soto Norte joint venture, 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.
