VANCOUVER, BC, March 5, 2025 /PRNewswire/ – Aris Mining Corporation (Aris Mining or the Company) (TSX: ARIS) (NYSE-A: ARMN) announces that the Colombian Ministry of Environment has completed the public consultation process initiated in November 2024 in respect of the resolution establishing a Temporary Reserve Area (TRA) in the Santurbán region of the Santander Department, where the Soto Norte Project is located. Effective March 4th, this resolution allows the Ministry of Environment to evaluate water resources in the area and temporarily suspend the issuance of environmental licenses for two years. As previously announced, this resolution does not affect Aris Mining’s Segovia Operations, the Marmato Mine or the Lower Mine Project, all of which are licensed and located outside the designated study area.

Neil Woodyer, CEO of Aris Mining, commented “Following the start of the consultation process for the proposed TRA that we announced in November 2024, Aris Mining has continued to advance environmental and technical studies of a smaller-scale version of the Soto Norte Project, with completion expected by mid-2025. Once finalized and with significant local support for the project from the Soto Norte community, we look forward to engaging with the Ministry of Environment and its new leadership, as our redesigned project aligns with the resolution’s focus on environmental protection. We are taking a new approach compared to previous permitting submissions, featuring scaled-down mining operations and processing facilities, a reduced environmental impact, and new processing options to support local small-scale miners. Building on our successful partnerships with small-scale miners at our other Colombian mine sites, the Soto Norte Project offers a responsible solution to reduce existing harm from unauthorized mining activities in the Santurbán region.”

The Soto Norte Project remains several years away from development and is planned to commence following the completion of the ongoing expansions of our Segovia and Marmato Mines.

About Aris Mining

Founded in September 2022, Aris Mining was established with a vision to build a leading Latin America-focused gold mining company. Our strategy blends current production and cashflow generation with transformational growth driven by expansions of our operating assets, exploration and development projects.

With expansions underway, Aris Mining is targeting an annual production rate of more than 450,000 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 ramp up in 2026. In addition, Aris Mining operates the 51% owned Soto Norte joint venture, where studies are underway on a new, smaller scale development plan, with results expected in mid-2025. In Guyana, Aris Mining owns the Toroparu gold/copper project, further diversifying its asset portfolio.

Colombia is rich in high-grade gold deposits and Aris Mining is actively pursuing partnerships with the Country’s dynamic small-scale mining sector. With these partnerships, we enable safe, legal, and environmentally responsible operations that benefit both local communities and the industry.
