On reading further, the price is the 15 day VWAP at the time that notice is given. Even at the low of around $2.75, the 15 day VWAP was still well above $3 so the company could have given notice (on the day of the $2.75 low) to draw without needing to get the sp back up first. In fact they must have given notice before the sp bounced as they announced the draw down before the bounce; "The facility has been drawn to $1m as at today". I.e. They had no need to mention the UK other than for continuous disclosure purposes - including to explain the reason for the draw down.
