Analysis · ARIS · Energy & Transportation
Aris Mining announced that Colombia's new administration has revoked three regulatory measures that had restricted mining authorizations and environmental licensing in the Soto Norte region — the La Baja Reserve, the Temporary Reserve Extension, and the 2026 Páramo Partial Delimitation. The Temporary Reserve Area now reverts to its original March 4, 2027 expiry, aligning with the company's project timeline. With the ESIA preparation complete and community engagement launching in October, Soto Norte — a 4.6 million ounce high-grade gold project — is positioned to advance toward environmental licensing and a construction decision. This removes significant regulatory uncertainty that had clouded the project's path forward.
