*The Q4 2024 results provided in this news release are approximate and may differ from the final results to be included in the Company’s 2024

annual audited financial statements and MD&A, which the Company expects to release in early March 2025.

Neil Woodyer, CEO of Aris Mining, commented “Looking ahead to 2025, we expect total gold production of

between 2 30,000 and 2 75,000 o unces as we begin to realize growth from our expansion projects. At

Segovia, the processing facility's capacity is being expanded by 50% 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 December 31, 2024 , we hold US$253 million 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, w e 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 October 7, 2024, Aris Mining announced it was targeting gold production of between 185,000 to 195,000 ounces in 2024 from the

Segovia Operations and leaving 2024 production guidance for the Marmato Upper Mine unchanged at 20,000 – 25,000 ounces.
