The War Eagle claim (Lot 678) is 700 metres south of the Phoenix pit (082ESE020) and adjoins the Aetna (082ESE022) and Grey Eagle (082ESE018) claims, situated to the north and west, respectively. The claim was Crown granted to R. Denzler and T.W. Johnson in 1897.

The mine was first developed by a two compartment vertical shaft sunk to the 30-metre level, which is also connected to the surface by a 100-metre long adit crosscut driven from the south. The ore was delivered from the property by gravity tram to a spur line of Canadian Pacific railway extending west from Hartford junction. This work was done by the Consolidated Mining & Smelting Company of Canada in 1909. In 1928, the War Eagle and other surrounding claims were held by the Hercules Consolidated Minng, Smelting, and Power Corporation, Limited. No clear documention of production exists for the War Eagle; minor production may be included with the Showshoe (082ESE025).

The principal mineralized zone is hosted in sharpstone conglomerate (Triassic Brooklyn Group) above the main level, except at the north end of No. 2 north crosscut, where the ore dips a low angle to the north and west, below the main level. The ore consists of finely disseminated chalcopyrite and pyrite in a dense epidotic gangue and coarser irregular bands of grey calcite and quartz. A diamond drill hole through this ore body showed a vertical thickness of 9 metres.

A large body, averaging about 11 metres thick and composed mostly of magnetite and pyrite (with little or no copper mineralization), was encountered in crosscut No. 1 north, above the main level. This body measures 40 by 50 metres in plan projection and dips gently to the north.

Trenches in the northeast part of the claim expose massive magnetite and pyrite lenses across widths ranging from 9 to 15 metres. However, many of the open cuts show only lean ore or barren gangue with an abundance of massive green epidote containing some pyrite and calcite.
