The Eagle Heights showing is located on the southeast side of Eagle Heights Mountain between 550 and 610 metres elevation, 32 kilometres northwest of Victoria.

The showing consists of a 107 to 300 metre wide band of lime- stone of the Upper Pennsylvannian to Lower Permian Mount Mark Form- ation, Buttle Lake Group (previously Buttle Lake Formation, Sicker Group). The band, which trends westward for 1370 metres, is overlain to the northwest by metabasalts of the Upper Triassic Karmutsen Formation, Vancouver Group and underlain to the southeast by sediments of the Upper Devonian McLaughlin Ridge Formation, Sicker Group.

The band is comprised of coarse-grained, light grey, fossil- iferous limestone with chert and volcanic inclusions. A chip sample taken across 55 metres contained 47.10 per cent CaO, 0.82 per cent MgO and 12.40 per cent insolubles (McCammon, 1973, page 8).
