Ive also been buying a few over the last few days. With over two months until the expiry date, there shouldn't be such a big gap imo. We are expecting the PFS in the next week or two which could move the share price quite a bit. A 50% rise in the share price should equate to a 100% increase in the options so they still offer good leverage.
There was 300,000 options exercised recently, it would be easy to sell these on market for around 45c and then re-buy the options for 20c and make an instant 5c per share for little work.
