I'll respond based on what I think "Bunti" might be thinking as I agree he rarely provides detail on his trading strategies:
Do serious investors invest in stocks that issue a news release on just one drill hole hitting what are pretty average grades?
Do serious investors anticipate a stock being valued based on $30 moly?
Do serious investors extrapolate or interpolate? Do they invest off JORC / NI calculations or just drill holes? Are they optimists or realists or pessimists?
Do serious investors compare a stock with all the others out there and perform comparative valuations.
