The Horne claims are located 1.5 kilometres west of Cameron Lake, approximately 10 kilometres northeast of Port Alberni.

The area is underlain mainly by Paleozoic Sicker Group rocks of the Nitinat, Myra and Buttle Lake formations and lesser amounts of Triassic basaltic rocks of the Karmutsen Formation. A major north westerly striking fault zone runs through the property with associated local shear deformation and listwanite alteration in Sicker Group volcanic and volcaniclastic rocks.

Mineralization includes pyrite associated with listwanite (quartz-carbonate alteration), common disseminated sulphides and fracture controlled sulphides. Iron bearing sedimentary rocks are also noted.

In 1984, the area was explored as a part of the Comedy Group and was restaked as the Mero 1-3 claims in 1985. In 1987 and 1988, Nexus Resources Corp. completed programs of geochemical sampling, geological mapping, prospecting, geophysical surveys and 1557 metres of diamond drilling on the property, now a part of the Horne claims and Cathedral Group. Rock samples have returned values up to 120 parts per billion gold, 494 parts per million lead, 5.4 parts per million silver and 1424 parts per million zinc (Assessment Report 17474).

In 1990, a program of prospecting and rock and silt geochemical sampling was completed by E.W. Hayes on the area as the Ho 1-4 claims.
