Yes, they did sell stockpiled low-grade ore from previous mining. XX was correct on that. AMG promotional video geo(s) spoke glowingly of widespread medium - high grade gold at surface over long distances from surface sampling so it should not be too difficult to selectively mine small pits from a number of sources. Clearing it with the Mines Dept can cause some delays but it is unusual to have such opportunities at the surface and over long distances. AMG saying that "may" be amenable to bulk mining is just conforming to ASX rules.
