\nAris 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.<\/p>\n
\nThe bridge is an early infrastructure initiative being advanced by Aris Mining\u2019s Guyana project team while the Toroparu Pre-Feasibility Study (PFS) continues. Toroparu\u2019s 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.<\/p>\n
\nNeil Woodyer, Chair and CEO of Aris Mining, commented: \u201cWith 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.\u201d<\/p>\n
\nThe 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.<\/p>\n
\nConstruction 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.<\/p>\n
About Aris Mining<\/b><\/p>\n

\nThe Company is advancing expansion projects at Segovia and Marmato that are expected to increase annual gold production to approximately 500,000 ounces1<\/sup>, driven by the ramp-up at Segovia following the installation of the second mill which was completed in June 2025, and construction of the new Marmato bulk mine and CIP plant, with first gold expected in Q4 2026.<\/p>\n \nAris Mining\u2019s portfolio supports a longer-term objective of approximately 1 million ounces of annual gold production2<\/sup>.

For more information, please refer to the Company\u2019s news releases dated June 30, 2025 regarding the Segovia expansion and March 12, 2025 regarding the Marmato expansion.<\/p>\n<\/td>\n<\/tr>\n 2<\/sup> Includes potential production estimates from Toroparu, which is based on a preliminary economic assessment effective October 21, 2025, which contemplates a 7.0 Mtpa operation over a 21.3-year mine life with average annual gold production of approximately 235 koz at a base case gold price of US$3,000\/oz. The preliminary economic assessment is preliminary in nature and includes inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that the preliminary economic assessment will be realized. Mineral resources that are not mineral reserves do not have demonstrated economic viability. There can be no assurance that the projected production will be achieved. Such production also remains subject to obtaining all necessary permits and to formal construction decisions by the Company, in each case for both Soto Norte and Toroparu.<\/p>\n<\/td>\n<\/tr>\n<\/table>\n \n\u00a0<\/p>\n View source version on businesswire.com: <\/span>https:\/\/www.businesswire.com\/news\/home\/20260908863772\/en\/<\/a><\/span><\/p>\n Aris Mining<\/b><\/p>\n O<\/b>liver Dachsel Lillian Chow KEYWORDS:<\/b> South America Australia North America Canada Guyana United States Africa Australia\/Oceania<\/p>\n INDUSTRY KEYWORDS:<\/b> Mining\/Minerals Natural Resources<\/p>\n\n
