We need to stop judging an announcement by the price action for a few hours, unless you are an intra-day trader.
It's a great news from the business angle - this is the start of a massive drilling program that will enhance shareholders value through increase in total resources and reserves/LOM. We all know from other mining companies that the share price rise significantly during the drilling program (progressively when interim drilling results are published).
