Issues Relating to Quarries and Deleterious Materials: Discussion
Ms Yvonne Wylde:
On the mica, there are other ways of identifying it. It is not called a mica test but there are other ways like the petrographer's report, the geologist's report and the percentage finds. The control over the percentage finds is where the mica would be found. They are not called mica tests, as I said, but there are other tests that establish if mica is present. If there is an indicator maybe you go to the next level but there are definitely tests there around establishing those materials.
