The limestone is generally dark to bluish grey, comprising limestone bands, 10mm to 1m thick separated by thin shale or siltstone |
laminae. |
The limestone is crushed on site and then trucked to Tamaree for processing to produce mainly burnt lime and quick-lime. Road base and |
screenings are also produced from the quarrying operation. |
