The Cascade prospect is located about 27 kilometres northeast of the community of Hope, and is underlain by green-white coarse-grained granite of the Eocene Needle Peak pluton.
Test splitting of large boulders for building stone use has taken place late in 1992. The stone contains feldspar crystals up to 2 centimetres in diameter which have indications of zoning with light beige centres and greenish rims with white feldspar as pale matrix elsewhere. The rock contains occasional hornblende crystals.
The operator is B.C. Granite Ltd. of Burnaby. Available potential quarry sites are in several places of the valley.
Margranite Industry Ltd. possibly produced Alpine Summer from this quarry.
