Regarding Mace ,I spoke to someone at the RMS meeting who was saying there was a particular WA law which meant the land owner could veto and that was some risk there .Seemed strange but had a look through the mining laws this morning and saw this :
Mining tenements on private landConsent of owner and occupier to grant in respect of surface landSection 29A mining tenement in respect of the natural surface and to within a depth of 30 metres thereof shall not be grantedin respect of private land which is:• in bona fide and regular use as a yard, stockyard, garden, orchard, vineyard, plant nursery or plantation;• under cultivation (ie. used for agricultural purposes including cropping or pasturing; whether cleared or uncleared,used for grazing stock in the ordinary course of management of the land);• the site of a cemetery, burial ground or reservoir (ie. a dam, bore, well or spring)• land on which there is erected a substantial improvement (as adjudged by the Warden);• within 100 metres of any private land referred to above;• a separate parcel of land having an area of 2000 square metres or less;except with the written consent of the owner and occupier of that land.
