Ann: Exploration Update, page-37

My guess would be three or four weeks, these targets are much shallower so I don't think well have to wait very long to know the results from drilling these conductors.
Plus the report itself said that "Regionally, surface exploration activities on other target areas within the Mt Ridley project are ongoing, including air core and auger drilling on selected gravity/magnetic features." Therefore there is still some sort of drilling going on, so I'm not sure how long it would take for them to get the other type of drilling operation going but if they're already on site, possibly not that long.
However that is just a complete guess as I don't have any idea what's involved, I'm sure Ash or somebody at the company could give you a rough estimation of the timeframe invovled.
