TOMRA Mining LASER technology changes the way things are done in gold processing

Located approximately 200 km northwest of Sydney, between Bathurst and Mudgee, the Hill End project encompasses a significant portion of the historic Hill End goldfield. This region, part of the Eastern Lachlan Fold Belt, has historically yielded over 1.6 million oz of gold and is renowned for producing large gold nuggets, including the famous Holtermann Nugget.

The project's geology features gold mineralisation associated with quartz veins within the Chesleigh Formation and Crudine Group. These characteristics make the ore amenable to gravity separation techniques, allowing for high recovery rates without the use of chemicals.

In pursuit of enhancing ore processing efficiency and reducing environmental impact, Vertex Minerals has incorporated TOMRA Mining's LASER ore sorting technology into its processing workflow. This sensor-based technology enables precise separation of ore from waste rock, improving feed grade and reducing the volume of material processed downstream.

The integration of LASER sorting complements the existing gravity-based processing plant, which includes crushing, ball milling, and concentration equipment. By pre-concentrating ore before it reaches the mill, Vertex achieves higher throughput and lower energy consumption.

Roger Jackson, Executive Chairperson, Vertex Minerals, said:

“Vertex decided to open up this mine because it was already permitted, it was a high-grade gold mine, and we could see an opportunity to have one of the best high-grade gold mines in Australia.”

Gavin Rech, Area Sales and Technical Manager Australia at TOMRA Mining, said:

“What excites me about this project is to work with a team like Vertex and this beautiful historic site, and mine in a more efficient and intelligent way.”
