ARIS MINING: All Workers Safely Recovered at Segovia Partner Mine

VANCOUVER, BC – Aris Mining Corporation (TSX: ARIS) (NYSE-A: ARMN) announced today the safe recovery of all 23 workers who were underground during a recent shaft collapse at the La Reliquia Mine. The group included five Aris Mining employees conducting a routine operational review.

The company’s Brigade of Prevention and Emergency Control responded immediately, ensuring a safe resolution to the incident with no reported injuries.

CEO Neil Woodyer stated, “We are incredibly relieved and grateful that all workers are safe. I commend our rescue team and the La Reliquia workforce for their swift and professional response. We also extend our thanks to the families and the local community for their patience and support during this challenging time.”

The La Reliquia Mine, a partner to the Segovia Operations since 2014, contributes a small percentage of mill feed to Segovia’s overall production. According to the company, the incident has not impacted ongoing operations at Segovia.

About Aris Mining

Aris Mining, established in September 2022, focuses on building a leading gold mining company in Latin America. Its growth strategy emphasizes current production and cash flow generation alongside expansions of existing assets and exploration and development projects. The company aims to unlock value through scale and diversification and is listed on the TSX (ARIS) and NYSE-A (ARMN).

Aris Mining operates two underground gold mines in Colombia: the Segovia Operations and the Marmato Complex. In 2024, these mines produced 210,955 ounces of gold. With expansions underway, the company is targeting an annual production rate exceeding 500,000 ounces. This target hinges on the commissioning of the second mill at Segovia, completed in June and currently ramping up in the second half of 2025, and the ongoing construction of the Bulk Mining Zone at the Marmato Complex, which is anticipated to begin increasing production in the second half of 2026. Beyond these core assets, Aris Mining holds a 51% stake in the Soto Norte joint venture. A Preliminary Feasibility Study (PFS) has been completed for a smaller-scale development plan that the company believes will establish Soto Norte as a high-quality, long-term project with sound economics and strong environmental and social design features. Additionally, Aris Mining owns the Toroparu gold/copper project in Guyana, where a new Preliminary Economic Assessment (PEA) is underway to evaluate potential development scenarios.

Colombia, rich in high-grade gold deposits, represents a key geography for Aris Mining. The company is actively seeking partnerships with the country’s small-scale mining sector, aiming to promote safe, legal, and environmentally responsible operations that benefit both local communities and the broader industry.

Analysts’ Commentary:

The incident at La Reliquia raises questions about safety protocols at Aris Mining’s partner operations. While the company reports no disruption to Segovia’s production, investors will likely scrutinize future safety reports and operational reviews closely. The successful recovery of the workers is a positive outcome, but the incident highlights the inherent risks associated with underground mining and the importance of robust risk management practices. The medium-term outlook for Aris Mining remains tied to its expansion plans at Segovia and Marmato. Successful execution of these projects is crucial for achieving the company’s targeted production increases and solidifying its position in the Latin American gold mining sector. The updated PEA for the Toroparu project in Guyana will also be a key catalyst to watch, providing insights into the potential for future growth beyond Colombia.
