Snapshot	The Arctos Anthracite Project is a proposed coal mining development in northwestern British Columbia, focused on extracting anthracite, a high-grade form of coal used in steelmaking. The project has faced strong opposition from the Tahltan First Nation due to its location in an area of cultural and ecological importance, which has led to delays and required negotiations with the BC government. In May 2015, the Arctos licences were sold to the provincial government’s rail corporation, with the sellers retaining a 10-year option to repurchase them at the same price. In Q1 2025, it was confirmed that the repurchase option expired on May 1, 2025, and was not exercised.

Deposit type

• Sedimentary

Summary:

The anthracite deposits at the Property are part of significant coal measures within the Bowser Basin. This ancient basin formed and filled with sediments eroded from surrounding high land during the late Jurassic to early Cretaceous periods.

The Klappan (Anthracite) Formation sediments are interpreted to have been deposited in a regional, shallow gradient, stable coastal delta (Gulf 1988). The environments of deposition cycled between fluviodeltaic and marine. The coal seam deposition is an extreme of the cycles, with an average of 20 to 30 metres of mudstone, siltstone and sandstone separating the coal seams. The interburden lithology generally consists of laminated mudstone, siltstone and fine-grained sandstone. Occasional deposition of coarse sandstone and conglomerate occurs.

Anthracite seams are encountered on the Arctos Anthracite Property. Anthracite is the highestrank coal under international coal classification standards. Anthracite on the Property occurs in 33 identified seams with individual seam true thickness of up to 11 metres; 28 of the seams have an average true thickness of at least 0.50 metres and contain at least 50 percent coal.
