GSSO commenced its activities in late 2013. It had a budget of more than AUD 1.7 M, with a 3.5 year duration. GSSO Phase 1 benefited from the valued support of major sponsors: Minerals Research Institute of Western Australia (MRIWA), Codelco Chile, Glencore Mount Isa Mines, IGO Limited, MMG Limited, and the Australian Centre for Geomechanics. Minor project sponsors were: Atlas Copco Australia Pty Limited (now Epiroc), DSI Underground, Fero Strata Australia (now DSI Underground), Golder Associates Pty Ltd, Geobrugg AG, and Jennmar Australia. The sponsors not only offered significant financial contributions, but also a large pool of expertise that provides extremely valuable input into the research projects and development of the Guide. The project culminated with the publication of Ground Support for underground mines which is available for purchase at acg.uwa.edu.au/shop/gsso.
