RE:Share price I would guess that the price drop has less to do with the lack of news on the drilling, and more to do with the attack on the price on gold recently.
My suspicion is that this is happening much along the lines that Alasdair MacLeod has suggested.
That is, many of the major banking entities are heavily short in G&S, and, with European banks looking at an initial phase-in of Basel III on June 28, many of them are desperate to close out those short positions before then. (The UK gets a reprieve until Jan 2, 2022, and Comex is pretty much tied to LBMA).
That's only 11 days from today. This is the hourly gold chart for June.
