The Vedder Mountain aggregate property is located 1.5 kilometres northwest of Cultus Lake, approximately 7 kilometres southwest of Chilliwack.

Regionally the area is underlain and surrounded by four formations. To the north of the claims lies the Chilliwack Group described as Devonian to Permian undivided sedimentary rocks. To the south of the claims is the Kent Formation, which consists of an Upper Jurassic mixture of conglomerate and come clastic sediments. East of the Kent Formation and on the southeast comer of the claims is the Cultus Lake Formation, which is a Late Triassic to Early Jurassic sequence containing mudstones, siltstones, shales, and other fine clastic sedimentary rocks.

Immediately underlying the claims and forming the main host for the rock quarry is the Vedder Mountain metamorphic complex, which is Permian in age and is described as a sequence of lower amphibolite to kyanite grade metamorphic rocks.

Locally, they consist of a mixture of grey to green metamorphosed basalts and andesitic rocks. Rock conditions are generally massive and competent, and are locally cut by north easterly trending by south easterly dipping shear and fault structures.

The Vedder Mountain aggregate and rock quarry have been owned and operated by Kirkness Pacific Holdings Ltd. since at least 2006. In 2010, a program of aerial photography, surveying and mapping was completed on the property in preparation to expand the existing quarry.
