The Dome showing is located on Evans Creek, approximately 12 kilometres south-southwest of the community of Dome Creek.
The area is underlain dominantly by rocks of the Cariboo Terrane. These consist mainly of Hadrynian to Lower Paleozoic Cariboo Group metasedimentary rocks. In this area the underlying rocks belong to the Dome Creek Formation of the upper part of the Cariboo Group. The Dome Creek Formation is, here, considered to be of Cambrian age and consists of limestone, calcareous argillite, shale and quartzite.
Mineralization comprises chalcopyrite, galena and minor pyrite in brecciated zones of a 15 metre thick quartz sill between grey quartzite in the hanging wall and calcareous argillite in the footwall. The sill and the enclosing rocks strike about 85 degrees and dip 60 degrees south. Carbonate (probably ankerite) occurs as a secondary mineral within the sill.
The first record of work in the area comes from government geologist D. Lay in 1934. In 1958, Lido Mines completed rock trenching on the property. In 1969, a drill program totalling 300 metres was completed. In 1971, Kellex Mining Company held and explored the area.
