ARIS MINING PUBLISHES ITS 2023 SUSTAINABILITY REPORT

Aris Mining Corp. has published its 2023 sustainability report, which has been prepared in accordance with the Sustainability Accounting Standards Board for the metal and mining industry.

Neil Woodyer, chief executive officer of Aris Mining, commented: "We are pleased to present Aris Mining's 2023 sustainability report. In 2023, we made significant progress in our environmental, social and governance initiatives, adhering to industry best practices for the benefit of our stakeholders. Of particular importance in this regard is our contract mining partners program, which contributes over 40 per cent of our current gold production and is vital to our success in Colombia.

"By partnering with CMPs, we develop a shared value initiative that not only generates profitability for both parties, but also presents a solution to the environmental and social complexities arising from informal and illegal mining that has historically been an issue in Colombia. By helping to formalize more than 3,000 miners to date and planning to formalize an additional 500 to 1,000 miners in 2024, we are driving responsible and safety-focused mining practices that align with government policies, promote economic development and strengthen the social fabric in the regions in which we operate while exercising due care for the environment. These partnerships represent the future of mining in Colombia and offer sustainable solutions to the challenges associated with informal and illegal mining."

2023 sustainability report highlights:

• The company established a management sustainability committee, reporting directly to the chief executive officer and the sustainability committee of the board, which has facilitated transparent decision making and oversight of its sustainability initiatives.
• Its participation in the SASB standards and the Towards Sustainable Mining protocols reflect its commitment to rigorous ESG performance standards.
• In 2023, it became a member of the United Nations Global Compact, endorsed the United Nations Women's Empowerment Principles and increased the inclusion rate of women in its work force.
• It updated its materiality analysis in 2023 to cover both the Marmato mine and the Segovia operations.
• It has created an $11-million trust fund dedicated to the environmental rehabilitation of Marmato, which includes the construction of a water treatment plant to treat industrial waste water from its operation.
• It has invested $10.2-million in social and environmental projects, highlighting its commitment to creating shared value in the communities in which it operates and aligning with the United Nations Sustainability Development Goals. These investments prioritize education, socio-economic development, infrastructure, environmental conservation, and gender equity and inclusion.
• Following the adoption of the Vision Zer000 safety program in 2022, it achieved a 75-per-cent reduction in lost-time injuries.

About Aris Mining Corp.

Aris Mining is a gold producer in the Americas, currently operating two mines with expansions under way in Colombia. The Segovia operations and the Marmato Upper mine produced 226,000 ounces of gold in 2023. Aris Mining is targeting a production rate of approximately 500,000 ounces of gold per year in the second half of 2026, following a ramp-up period after the Segovia mill expansion, scheduled for completion in first quarter 2025, and the Marmato Lower mine's first gold pour in late 2025. Aris Mining also operates the 51-per-cent-owned Soto Norte joint venture, where feasibility-level studies are under way on a new, smaller-scale development plan, with results expected in early 2025. In Guyana, Aris Mining is advancing Toroparu, a gold/copper project.

Aris Mining intends to pursue acquisitions and other growth opportunities to unlock value through scale and diversification. Aris Mining promotes the formalization of traditional miners into contract mining partners as this process enables all miners to operate in a legal, safe and responsible manner that protects them and the environment.

We seek Safe Harbor.
