ARIS MINING ANNOUNCES COLOMBIAN MINISTRY OF ENVIRONMENT RESOLUTION RELATED TO THE SANTURBÁN REGION

VANCOUVER, BC, March 5, 2025 /CNW/ - 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.
