2025 AusIMM Life of Mine | Mine Waste and Tailings Conference

Practitioners from Geosyntec and Red Earth Engineering, a Geosyntec Company (REE) will make significant contributions at the 2025 AusIMM Life of Mine | Mine Waste and Tailings Conference.

The conference will be held from July 28 through 31, 2025, in Brisbane, Australia.

REE’s Jarrad Coffey, Martin Rojas, Jiajun Zhang, Leis Day, Marcelo Llano, Wade Ludlow, Nicolas Pereira, Oliver Dudley, Anna Goto, and Symon Jackson will speak, as will Rachel James of Geosyntec and David Reid of Geosyntec’s REELab.

Our speakers and many other attendees from the firm will be available at booth 42 during the conference. To advance the practice and promote knowledge sharing, we are an Engineering Sponsor of this global event.

AusIMM’s Mine Waste and Tailings Conference equips the global mining community with the latest in sustainable development. It will focus on all aspects of waste rock and tailings management throughout the mine’s life cycle, from site selection and design to post-closure care. Speakers and participants will address current and future challenges to the re-engineering of mining. AusIMM is a trusted voice for people working in the resources sector. Representing a global community working across 110 countries, the institute supports all aspects of the mining industry.
