The short version is that your shares are worth a small fraction of what they were when New Hope gave Dart away to Igas.
At that time Igas was trading at around 1.20-1.30
Now they are hovering around 0.17 (the all time low) having been in a strong downtrend for over a year and nothing is likely to make them rise in the near future.
Be prepared for them to go quite a bit lower.
