this recent run is most probably in relation to ROY's recent anouncements and the nearology factor as PMH have made mention of in yesterdays ann.
As for how far it could go? you only need to have a look at any stock within cooee of SFR's recent discovery and how the nearology factor has effected them.
Bear in mind PMH is one of those stock with the narraccota volcanics on it also
Not saying it could do something similar but the run in momentum can sometimes surprise most of us.
Good luck with it as looked at PMH a week or so ago around 17-19 cents based on it's nearology factor to SFR even though it is quite a distance but same structual control. (from memory anyway as looked at so many last 2 weeks)
