If you look at Moday afternoon's price chart you'll see a big spike in price and volume - highly likely short term traders caught up in the excitement with close to 2 million shares traded from 57.5 to 58.5c. Now look at the current market depth on the sell side: 2.2 million shares from 58c up to and including 60c. I think that's as good an explanation as any - especially as yesterday it traded sideways as you would expect after such an almost vertical spike - you would even expect maybe to trade a bit lower. I guess they don't want to sell at a loss and are waiting with their offers for their profit goals to be met.
