No delays would be good but in my experience there are no guarantees in the speculative mining business, which includes projected timelines. Too many possible variables to give more than just a rough guide IMO. I agree with you on the silica subject. I gave that a value of zero 12 months ago, if turns out well it's a bonus for me so won't be losing any sleep there.
