Producing GMA in Australia

Australian Garnet

Most of GMA’s superior product comes from the garnet-bearing sands in Western Australia. Through a unique geological history of erosion and deposition, these dune sands contain the highest quality garnet available anywhere in the world.

From Western Australia’s capital city of Perth, GMA manages a state-of-the-art mining, processing, refining, and shipping operation that includes resources in Geraldton and Port Gregory. The quality control imposed upon all aspects of the Western Australia operation has made GMA the leading supplier of blast cleaning and waterjet cutting abrasives in the world.
