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

Aris Mining Corp. has been informed by the Colombian Ministry of Environment that it has completed the public consultation process initiated in November, 2024, in respect of the resolution establishing a temporary reserve area (TRA) in the Santurban region of the Santander department, where the Soto Norte project is located. Effective March 4, this resolution allows the Ministry of Environment to evaluate water resources in the area and temporarily suspend the issuance of environmental licences 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, chief executive officer 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 Santurban region."

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