Eidsvold Siltstone was founded in 2000 by geologist Michael Whitty when he discovered the formation at Lochaber Creek near Eidsvold in regional Queensland.
This fine grained alumino silicate siltstone is derived from the adjacent Permian Eidsvold Granitoid Complex and settled into a Jurassic lacustrine lake system that was later intruded by Tertiary Volcanics and can be interpreted as a Volcaniclastic Siltstone.
Excited by the market potential of the unique stone, Michael acquired mining permits and approvals, leased the land from local cattle grazers and formed Eidsvold Siltstone - one of Australians first zero waste mines.
Over the years, Eidsvold’s white siltstone has become a highly sought after building material by top architects and builders across Australian and abroad.
At Eidsvold Siltstone, we’re proud of our community and equally proud to be an employer of locals from the Northern Burnett region.
ZERO WASTE MINE
Eidsvold Siltstone is committed to our sustainability targets of zero waste.
We do this by:
crushing all stone offcuts to make pebbles for landscaping
repurposing powder from sawing into furniture resin and eco-friendly cement starter
sourcing stone without the use of explosives or chemicals
re-using all waste water.
Our model is the sustainability benchmark for the Australian mining industry.
Blocks are extracted from the mine face using an Atlas Copco Air Track mounted rig drilling 25mm holes at 1 metre spacing and broken free by infilling with Expando cracking agent.
The resource is naturally fractured along horizontal bedding planes and sub vertical parallel fracture zones which is thought to have been brought on by techtonic forces with volcanism during the Tertiary Period.
