Aris Mining Begins Construction of the Puruni Bridge in Guyana
The permanent crossing will improve a key logistics link to the Toroparu Gold Project
Aris Mining Corporation (Aris Mining or the Company) (TSX: ARIS; NYSE: ARIS) has commenced construction of a permanent bridge across the Puruni River at Puruni Landing in Guyana. The 109-metre modular steel bridge will provide a permanent crossing in addition to the existing pontoon crossing, strengthening an important access route to the Toroparu Gold Project while also improving access for other users of the Puruni corridor.
The bridge is an early infrastructure initiative being advanced by Aris Mining’s Guyana project team while the Toroparu Pre-Feasibility Study (PFS) continues. Toroparu’s planned route includes moving heavy equipment and cargo by barge to Itaballi and then by road to Toroparu, crossing the Puruni River at Puruni Landing.
Neil Woodyer, Chair and CEO of Aris Mining, commented: “With our Guyana project team in place, we are pleased to begin this early infrastructure work while we advance the Toroparu PFS toward completion in Q4 2026. Working in cooperation with the Government of Guyana, we are delivering practical infrastructure that supports Toroparu and provides broader benefits in the region.”
The bridge is expected to improve connectivity for communities, businesses and other users of the Puruni corridor. The permanent crossing will allow heavy industrial traffic to be diverted away from the main community road.
Construction of the bridge is being undertaken by Aris Mining in coordination with the Ministry of Natural Resources, the Ministry of Public Works and other relevant agencies, with completion targeted for December 2026.
