This is a record of the proposed Tenas Project open-pit coal mine; near the confluence of the Telkwa & Wetzinkwa (Bulkley) rivers, and the towns of Telkwa & Smithers, in British Columbia.
The review is in its final phase. Town halls: Telkwa, October 10; Smithers, Saturday, October 17 at 1 pm (Della Herman Theatre). Organizers give the public comment period on the government’s draft findings as November 10 to December 10, 2026.
See the dates →The proposed Telkwa Coal mine will be visible from almost everywhere in the Bulkley Valley, and irreversibly despoil our beautiful home. The 3D map below shows the visual impact of the pit, ponds, and access corridor from any vantage point on land or in air.

Telkwa Mining held open-house sessions in Smithers and Telkwa, displaying twenty posters on the project. We transcribed every claim on every poster and answered each one from the record.
Walk the posters →The mine plan has been under government review since 2018. What the reviewers asked for, what the company answered, the ten major items raised, and what came of each.
Follow the review →Four Indigenous nations take part in the review. The material includes letters, requests, and the two technical reports written for the Office of the Wet'suwet'en.
Read documents →The proponent’s own drawings of the pit, the ponds and the dams at each stage, from first clearing to fifty years on. Step through them.
See the drawings →Three ponds behind four earth dams would hold the mine’s acid-generating waste under water above the Telkwa River. What they are, how their liners leak by design, where our flood maps come from, and what the company’s own study says a failure would do.
Read about the ponds and dams →The company predicts 950 tonnes of dust a year at the mine’s peak and calls the effect not significant. The Ministry of Environment’s reviewer called the modelling too uncertain to say. What the file holds from 2018 to 2026.
Read about the dust →Reviewers said the mine plan showed potential for significant harm to water. The company’s answer, about 3,300 distinct pages filed as 13,440, adds one new measure and no water treatment. A plain-language reading.
Read what they answered →A slowly recovering population of thirty-three caribou live on Wet'suwet'en territory, in a range once covering thousands of square kilometers. The proposed Tenas mine footprint sits inside the provincially-designated recovery area.
Read the story →The Tenas Project would produce metallurgical coal for Asian blast furnaces. Meanwhile, hydrogen-reduced steel is already shipping commercially in Sweden, and the European carbon border adjustment takes effect in 2026.

The Tenas Project is a proposed coal mine about ten minutes south of the town of Telkwa, in the Bulkley Valley and Wet'suwet'en territory in
British Columbia. The proponent has filed under several
corporate names — most recently rebranded to Telkwa Mining
Corporation. The EAO file under
project ID 5b905af23965330024d5b706 follows the project
across those name changes.
