If you're a long term holder what does it matter what the share price does in the short term or medium term?
They said they expected to be finalising something on the gas deal early 2018. We're only 4 weeks into the year.
The micro cap end of the market is crap and has been for a few weeks. There has been a broad sell off in 2018 so far. This is still trading at around the cap raising price. Not a bad effort to be honest especially when I look at some of my other micro caps.
