i need a crystal ball

I need a crystal ball to look into the future. I am still holding 40% of my total SIR holding.
Few days ago i could have sold for $5 a share, giving me massive amount of profits at zero cost. Today its down by 20%..what comes tomorrow?.
My rational thinking ask me to sell, but my greed ask me to hold..this is no longer investing but has becoming a gambling.

Is the $5 price a share already factoring SIR producing nickel, established JORC or what....? What is SIR true value?

I gotta admit the decision of when to pull the plug with SIR is one of the hardest decision i ever have in my life.
