In reality, the options did finish up today. Although the last trade price at 1.4c did not change, there is a buyer in the depth at 1.5c.
So, in my analysis, that means if a buyer is prepared to pay 1.5c, then that is the minimum price. With PDY at 3.2c in a fairly level trading range over the past three weeks, the options are fair value at 1.5 to 1.6c imo, that is a premium of 0.3c to 0.4c with over 19 months to run.
