The East Anderson River quarry is located in coarse-grained, green-white granite of the Late Jurassic and Early Cretaceous Eagle Plutonic Complex. Quarry Pacific Industries produces stone blocks from this quarry, to be processed into tile in Surrey.
The stone contains feldspar crystals up to 2 centimetres in diameter which have indications of zoning with light beige centres and pale greenish rims with white feldspar as matrix elsewhere. The rock contains occasional hornblende crystals.
In 1995, with Explore B.C. Program support, Quarry Pacific Industries Ltd. carried out a program of quarry preparation and development and some on-site block production from large boulders and outcrop. Limited quantities of two new products - Tiles of White Water and White Water Classico granite - were introduced on the market (Explore B.C. Program 95/96 - M148).
Margranite Industry Ltd. produces Aqua Mist from this quarry.
