Ok, I managed to get hold of the Mining Registrar this morning. As suspected, it's to do with an ERE.
He tells me that the DMNR have not actually declined my application - they just can't approve it because another government department has implemented an ERE in Reward and my applications happen to be on top of it.
He was pretty good about it actually, despite that I had gone ballistic at him on Friday. He says that if we want to call it quits, he will refund all of our money, not just the bond but the advertising fees etc as well. So that's good.
But if we want to press on, we will have to shell out some large sum to challenge the outcome. It seems unlikely that any of those involved in declaring the ERE have ever actually set foot on the land in question and looked around with their own eyes - they look at a grainy, long-distance photograph taken from space and from that they believe they can state to a certainty that some of the blurry, gray-green blobs are an endangered ecosystem and declare an ERE, shafting anybody in their road.
The Mining Registrar is sending me out the satellite maps and information from which I will try and work out what they are talking about - the vegetation on my claim applications consists mainly of a few gum trees and a swathe of buffle grass, an exotic grass introduced to Australia by accident. It seems they believe it is incumbent on the person who has physically been in the spot to prove what is or isn't there by paying for a botanist to do a vegetation survey, while they can legally declare what is or isn't there without ever having set foot there.
I wonder if these clowns realize that their ERE is actually a shared mining/pastoral lease and that Kielambete station graze their cattle in there and have done so for a long time?
