Aris Mining Achieves Significant Ramp-Up at Segovia Operations After Second Mill Commissioning

Aris Mining Reports Successful Expansion at Segovia

Aris Mining Corporation, listed on the TSX (ARIS) and NYSE-A (ARMN), has made impressive strides in enhancing operations at its Segovia site following the commissioning of a new mill in late June 2025. This strategic move significantly boosts the processing capacity and marks a pivotal moment in the company's ongoing growth strategy.

The newly operational second mill has upgraded the site's processing capacity by an impressive 50%, allowing it to handle 3,000 tonnes per day (tpd) compared to the previous rate of 2,000 tpd. This expansion comes as part of Aris Mining's plan to maximize production efficiency and optimize resource management in light of market demands.

According to recent reports, the processing rates have seen a dramatic increase over the summer months, with July and August averaging 2,415 tpd. This rate tops the preceding average of 1,971 tpd recorded in the six-month period ending June 30, 2025. Notably, on certain days in August, the throughput hit the maximum capacity of 3,000 tpd, showcasing the facility's robust operational performance.

Moreover, the average processed gold grades remained strong, with July and August registering 10.02 grams per tonne (g/t) of gold. This indicates that the company has effectively utilized its additional processing capabilities without sacrificing the quality of production, an essential aspect for maintaining profitability in the mining sector.

As of August 31, 2025, Aris Mining reported a total gold output of 141,893 ounces year-to-date, with 42,817 ounces produced during the months of July and August alone. The company's Marmato Narrow Vein zone also contributed a notable 4,936 ounces during this timeframe, pushing the consolidated gold production to 161,168 ounces for the year. This positions Aris Mining well to meet its full-year production guidance of between 230,000 to 275,000 ounces.

Aris Mining, established in September 2022, is committed to establishing itself as a formidable player in the Latin American gold mining industry. The company's strategy hinges on a mix of immediate production contributions coupled with longer-term transformational growth through the expansion of existing assets and development projects. The leadership team boasts a proven track record of success in generating value, ensuring operational excellence, and implementing strict financial discipline within the mining realm.

The Segovia Operations, along with the Marmato Complex, are central to Aris Mining's strategy, as both sites produced a cumulative total of 210,955 ounces of gold in 2024. With current expansion efforts, the company aims to elevate its annual output to exceed 500,000 ounces of gold over the next few years. The second mill's commissioning is just one component of their holistic growth approach, which also includes the construction of the Bulk Mining Zone at Marmato, anticipated to ramp up production by the second half of 2026.

Beyond its immediate operations, Aris Mining is also engaged in a joint venture through the Soto Norte project, which boasts a completed Preliminary Feasibility Study (PFS) confirming it as a high-quality project with solid economic viability and strong environmental standards. Furthermore, Aris Mining is examining the Toroparu gold/copper project in Guyana, where a new Preliminary Economic Assessment (PEA) is currently underway.

Colombia's wealth of high-grade gold deposits forms the backbone of Aris Mining's operational strategies. The company is keenly focused on forging partnerships with the local small-scale mining sector, ensuring that operations are safe, legal, and environmentally responsible, ultimately providing mutual benefits to local communities and the mining industry.
