Unless you expect coking coal to rally hard over the next few months, then it would be best to sell.

GUF's debt position is unsustainable at current levels and market conditions. They are unlikely to generate free cash flow from their mining operations, so the debt position is going from bad to worse. Cash position, as you note, is paltry and I can't see how they raise cash in the current market to cover operational cash outflow.

The only thing that has been going up is the share count - just take a look at how much new scrip has been issued over the last 3 years.

This probably isn't going to end well and the share price may end up at COK levels - so maybe time to cut your losses.
