long term sp and what to expect

Hi guys, as a long-term holder (i've been building up a relatively small holding over the last couple of years) I'm keen to learn more from even longer longs about the long-term SP.
Looking back at the 10 year chart for Flow/FAR, there's obviously a series of rises and falls, the more dramatic of which relate to past drills- rising in the build-up and falling sharply with news of the dreaded dust! The last of which being the Kora well.
Lets put Kenya aside for a moment (Kiboko will have some SP effect be it positive or negative) and look at the Senegal drills we have penciled in for next year. Given current levels of around 4c, how much do you reckon we can expect the price to rise in the lead-up and whilst drilling? Obviously a find would send us soaring but what's a reasonable guess for the price before then? 8c? More?
Any input appreciated.
