rmio query

Hi guys...
Hmm...i need your help.
My father passed away and im trying to figure out his finances. It seems that my father is holding RMIO options. Now, i really dont fully understand how options work...but its sitting at 0.001 now. Can you guys please help me with a few questions...

1) Were the options given for free upon owning RMI shares? or you have to buy the options?

2) Im confused. On the ASX website for RMI

http://www.asx.com.au/asx/research/CompanyInfoSearchResults.jsp?searchBy=asxCode&allinfo=on&asxCode=RMI&companyName=&principalActivity=&industryGroup=NO#details

it says...

Exchange Traded Options
No options are available over the security RMI

But isnt RMIO options!?

3) If i exercise the options...what does this mean? I buy the RMI shares at a given price?

I really appreciate this. Im so lost, and the options expire soon.

Thanks very very much!
