At the last AGM spoke to David about the low quality feldspar & suggested that it could be sold as road base material depending on it's hardness. He replyed that this was a great idea as the Coolgardie/Esperence highway was due for major road works. Anyone interested should check out what the price of Bluemetal is worth in it's various sizes. Apart from the topsoil we have no waste, but hardness of the rock is key. Exploration at the dome will take several years, but as MFG say's it should be of the highest priority. I already know as i have said before there are other commercial minerals at the Dome & i am sure we have just scraped the surface. GLTA.
Most rock can be crushed for road base. The overburden should mostly be suitable as crusher feed to produce road base. rock for bitumen screenings requires fairly high hardness and is a bit more difficult to source. Granite is generally suitable for both and I suspect that any fedspar would also be suitable for both. Any rock crushed for bitumen screenings would have to be fresh or close to. If the WA Main Roads are engaging in an upgrade to the highway past our dooe some of the "waste" rock should be saleable to a contractor experienced in producing road materials. He should pay some thing for rock already in stockpile. Don't expect too much (perhaps $5 a tonne) but it is something. Also the quantity required at that site is probably less than what is available

Reply back from a GeoMech lab - unlikely felspar would be used on a major road project much is the pity.
