Don't worry to much about the options. They will not come into play unless the SP is over 30c. I am personally looking forward to converting my options because that means that my shares are worth a lot more than they were when I bought them.
If the SP goes over 30c as we all expect it will mean that production is proceeding as planned and there may be further plans for expansion. In that case the funds from the options along with sales will enable this expansion without further fund raising.
This is a fairly simplistic view but hopefully shareholders will not stress over the options.
