Elexon Mining works with customers and collaborators around the world. From Brendale, in the outer northern suburbs of Brisbane, the technology and systems developed by Elexon and its partners benefits mining operations as far afield as Northern Canada and the remote interior of Chile.

Collaboration: Wireless Sensing Markers

Networked Smart Markers (NSM) are novel subsurface deformation monitoring devices able to transmit data wirelessly through the rock mass. They have the potential to overcome some limitations of currently available technologies: short lifespan, limited application depth, limited number of sensors per borehole among others. Two mine scale trials were conducted to asses the reliability of wireless data transmission through rock and the ability to get qualitative subsurface deformation measurements. The System performed successfully fulfilling both objectives of the trials and allowing the installation procedures, data acquisition and management and communication protocols to be tested and validated.


This project is a collaborative effort and the Authors would like to acknowledge the support of: Fundación CSIRO Chile through the Smart Open Pit Slope Management Project under the auspices of CORFO; the University of Chile, Advanced Mining Technology Center and the mining company, who have provided strong support to the Project from its commencement.

Collaboration: Cave Tracker

In collaboration with Rio Tinto, CRC Mining and Newcrest, Elexon Mining has developed the Cave Tracker System. This world first system allows mine operators to see movement in the cave in near-real time – a world first achievement realised through the power of working together.

Case Study: Resolute’s Mt. Wright Mine

Successful Sublevel Shrinkage at Mt. Wright: The Smart Marker Solution, which has been used by Resolute Mining at the Mt Wright underground gold project in Queensland, has had a positive impact on operations.

Senior Mining Engineer Stuart Long says the Smart Marker System by Elexon Mining is a window into sublevel shrinkage, which is very similar to sublevel caving, at its operations at Mt Wright; and in this regard the technology has been very beneficial. Resolute has been using the Smart Marker System since July, 2011.

“The Smart Marker System has enabled us to make improvements to our drill and blast activities, which has resulted in better ore recovery,” Long says.

As demand for minerals continues to grow, the mining sector faces the challenge of economically and safely accessing deposits that are deeper underground. But, “the deeper you go, the more expensive it is to mine,” Chair of Minerals Industry Engagement, mining engineer and Professor at University of Queensland Gideon Chitombo said.

Partnerships: Exciting new development – in-situ ore tracking

Collaborative working relationships that connect industry with technology experts result in targeted products that help to improve safety, productivity and profit.

The underground mining industry is keen on innovative technologies that will reduce the risks associated with mining methods like block caving, and a team of industry experts say they have the solution.

CRC Mining, Newcrest Mining and Elexon (the company that introduced the Smart Marker technology to the underground mining sector) are working in partnership to develop the Cave Tracker.
