The high volotility today shouldn't have come as a complete surprize to anyone. NOT at this time is still highly speculative and rumours, press and just ants in the pants on the part of individuals will cause what your seeing today.
The rapid rise in market price came without any release of drill results or assays so the reverse can also happen. Until the smoke clears and deposits are defined it's a wide open speculative play.
Of course the brokers will play games, sometimes it pushes price up and sometimes down. Roller coaster time and it's just as likely to be higher tomorrow. Just bet the day traders love this.
