Canada Carbon's Miller graphite mine project, Canada

The CPTAQ finally suspended the Miller mine in July 2021. This is a half-victory though. The company can nonetheless continue exploration work for the time being


The Canadian company Canada Carbon's Miller graphite mine project is located 80 km west of Montreal in the Township of Grenville. The Miller mine is a historical deposit of graphite and mica which was originally mined between 1845 and 1900. As of 2012 new studies were conducted by a geologist while the company Canada Carbon acquired 71 mining titles (claims), located on both sides of the Red River. The areas newly acquired by Canada Carbon covered ​​4,152 hectares, which is to say nearly a third of the municipality of Grenville-sur-la-Rouge. Phase 1 of this new project would consist in the extraction of marble and graphite from three open pits and the construction of an on-site flotation plant, which would occupy a total area of ​​62 ha. The construction of a heat treatment plant in Asbury, 150 km northwest of the Miller site, is also being planned. Annual production is expected to amount to 1,515 tons of seam graphite (very high purity, nuclear quality) and 150,000 tons of marble [1] [2] [3].
