ARIS MINING ACHIEVES 2024 PRODUCTION GUIDANCE AND PROVIDES 2025 OUTLOOK

Aris Mining Corp. had 2024 gold production of 210,955 ounces (oz) from its two operations in Colombia, with 187,583 oz from Segovia and 23,372 oz from the Marmato upper mine, and achieving the revised 2024 guidance range of 205,000 to 220,000 oz (1).

2024 gold production highlights:

• Gold production of 57,364 oz in Q4 (fourth quarter) 2024, delivering the highest quarterly production of the year;
• Gold production in the second half of 2024 of 110,972 oz was 11 per cent higher compared with H1 (first half) 2024.

Neil Woodyer, chief executive officer of Aris Mining, commented: "Looking ahead to 2025, we expect total gold production of between 230,000 and 275,000 ounces as we begin to realize growth from our expansion projects. At Segovia, the processing facility's capacity is being expanded by 50 per cent to 3,000 tonnes per day (tpd). Construction remains on track for completion in Q1 2025, with commissioning scheduled for Q2 2025. The mill feed rate is expected to increase gradually during the second half of 2025, rising from the current 2,000 tpd to the full 3,000 tpd by year-end. Meanwhile, construction of the Marmato lower mine continues to progress, with combined production from the upper and lower mines expected to ramp up in 2026.

"As of Dec. 31, 2024, we hold $253-million (U.S.) of cash, providing strong funding for these projects. Following project completion and ramp-up, we are targeting annual gold production of approximately 500,000 ounces. Additionally, we are advancing key strategic priorities, including environmental and technical studies at the top-tier Soto Norte gold-copper project. Results of these studies are expected in mid-2025. Aris Mining is well positioned for both near and long-term growth and value creation."

(1) On Oct. 7, 2024, Aris Mining announced it was targeting gold production of between 185,000 and 195,000 ounces in 2024 from the Segovia operations, and leaving 2024 production guidance for the Marmato upper mine unchanged at 20,000 to 25,000 ounces.

2025 gold production and AISC (all-in sustaining cost) guidance:

• During 2025, Aris Mining expects consolidated gold production of between 230,000 and 275,000 oz, with in-progress expansion projects to contribute to production growth in 2025 and beyond.
• In 2025, the Segovia operations are projected to produce between 210,000 and 250,000 ounces of gold, with approximately 50 per cent to 55 per cent sourced from Owner Mining and 45 per cent to 50% from mill-feed purchased from contract mining partners (CMPs). For the Owner Mining segment, AISC (2) per ounce sold is expected to range between $1,450 and $1,600 (3) and the CMP segment is expected to achieve an AISC (2) sales margin of 35 per cent to 40 per cent.
• Aris Mining will resume providing AISC guidance for the Marmato mine when the lower mine achieves commercial production, which is expected in 2026.

Aris Mining operates two underground gold mines in Colombia: the Segovia operations and the Marmato upper mine, which together produced 210,955 ounces of gold in 2024. With expansions under way, Aris Mining is targeting an annual production rate of approximately 500,000 ounces of gold following the ramp-up of the Segovia mill expansion, expected during the second half of 2025, and the new Marmato lower mine, which is expected to reach full production in 2026. In addition, Aris Mining operates the 51-per-cent-owned Soto Norte joint venture, where studies are under way on a new, smaller-scale development plan, with results expected in mid-2025.
