If they are only drilling diamond, it will be 2 shift, 24/7 drilling at approx 25m per shift on average (deeper the hole, slower the rate). I'd say they are well and truly finished, especially if the first 4 holes were disappointing. Also little doubt in my mind that the share price ran up to the 8th Jan drilling 'underway' (keep in mind the drill rig was on site and 'drilling programme underway" in Dec as per dec Qtrly), and subsequently fell all the way back on disappointing results. Don't need lab assays to know what you got with base metals...

I'd go further and say drilling at Bullhorn could be well underway and possibly the first hole past target depth... in which case they have a good idea what the IP anomaly is caused by, in which case nobody buying the rumour of success (hardly a bid at 3.4c in a rising copper price and general market) indicates more disappointment. All IMHO, based on the theory good news leaks into buying on market and bad news the opposite. Could be a new discovery has been made and kept secret though... who knows for sure
