Producing GMA in Australia

A man working on site work
GMA’s mining operations in Australia produce a superior quality of mineral that comes from the garnet-bearing sands found near Port Gregory in Western Australia. Through a unique geological history of erosion and deposition, these dune sands owned by GMA contain the highest quality garnet available anywhere in the world.
 
Our advanced mining, processing, refining, and shipping operation supply superior GMA Garnet™ abrasives to customers around the globe.



Quality Assured

 The quality control measures implemented throughout the refinement are a significant part of the GMA process. Heavy mineral concentrate is sampled prior to leaving the mine, at several transition points during processing, and again as a final product to ensure only garnet meeting the rigorous GMA standards is delivered to our customers. 
 
GMA takes pride in the fact that our product is undisputedly the highest quality natural abrasive and cutting medium available in the world today. The entire production process from mining to processing and administration is certified under various international quality standards, including:
  • ISO 9001:2015 (Quality Management Systems)
  • ISO 14001:2015 (Environmental Management Systems)
  • AS/NZS 4801:2001 (Occupational Health & Safety Management Systems)
  • In compliance with ISO 11126-10:2017 for free silica content.
