GMA Garnet Group (GMA) is an organisation that mines, processes, exports and distributes the highest quality garnet globally. Established over thirty five years ago, GMA is now the world’s largest and most advanced garnet mining and processing operation supplying garnet abrasive to the waterjet cutting and protective coating industries.
Garnets are a group of silicate minerals used as gemstones and abrasives. Mined garnet comes in many forms and is utilised for abrasives, cutting and filters. In Western Australia, garnet is a mineral sand and is considered one of the optimum products in the world for industrial applications such as waterjet cutting and sand blasting.


Operating in the Midwest region of Australia, GMA was established in the 1980s when it started exploration along a small stretch of coast line in the town of Port Gregory where geologists found small deposits of garnet. In 1983 GMA established a dry processing plant in Geraldton, a significant milestone for their operation, where it is still located today. These garnet bearing sands in Western Australia have a unique geological history of erosion and disposition resulting in them comprising of the highest quality garnet available anywhere in the world.
GMA took delivery of their very first Volvo in 1989 and over thirty years on, are still running a fleet of Volvo machines.


The very first business to purchase the Volvo L350F wheel loader in Australia, GMA Garnet is now the first Australian company to own Volvo’s largest excavator, the mighty EC950E.
With a knockout bucket breakout force of 478 kN (ISO 6015) and an arm tearout force of 420 kN (ISO 6015), the 90 tonne EC950E is a ground breaker in its class, offering superior digging force, when working with hard and heavy materials. As well as higher digging force, the momentous crawler excavator offers quick cycle times thanks to the enhanced hydraulics system which increases pump power for a fast and smooth operation. The EC950E is built with protected components, including a heavy-duty boom and arm, and a strong frame structure, and can be relied on for longevity and sustained uptime in demanding applications. Featuring a wide track gauge, long track length, retractable undercarriage, and an optimized counterweight there is no environment too challenging for this solid machine.
GMA use a variety of Volvo machines at their operations North of Geraldton in WA. They have A45G and A60H Volvo articulated haulers for carting ore from various pits to plant and backloading of waste from plant to pit. The team say the addition of Volvo’s largest hauler, the A60H, has increased their productivity due to the extra payload.


GMA also operate Volvo L350H wheel loaders in the processing plant to load ore into hoppers and tailings onto trucks, while their excavators are used on the front line, getting product out of the ground and into the trucks.
GMA says that Volvo has been proven to be high quality, reliable machinery since the beginning and have always had an outstanding name in the industry.
Moving upwards of ten thousand tonnes of materials per day, the ability to maximise operator productivity is essential. GMA’s operators shared their appreciation of the ergonomic layout of the instruments and controls in the Volvo machines making for better comfort and reduced fatigue. The new Volvo EC950E features a spacious cab, with a low noise environment and greater comfort.


GMA focuses on strong partnerships and an unwavering dedication to their customers. Much like CJD Equipment and Volvo Construction Equipment, their values surround trust, teamwork and care for their people and the environment. These collaborative values are what has built such a strong relationship between GMA and CJD Equipment over the last thirty years. GMA says the remarkable back up from the CJD team, their product support and knowledge of equipment requirements are what has helped build this relationship to what it is today.
GMA have led the way in innovation and the development of new products for the global abrasive blasting and waterjet cutting industries. With such an innovative outlook, it is no wonder they were the first to acquire Volvo’s latest edition to the Australian market and their largest excavator, the EC950E.
CJD Equipment and Volvo Construction Equipment are proud to provide GMA with the resources and services they need to move forward and drive innovations into the future.
