interesting little stock

Hi all,

Been researching this stock and am quite impressed with the potential it offers. Got a few questions I can't seem to find info on:

It might be a bit premature to be talking about but have the company indicated anywhere what the potential cash costs would be per oz? They mentioned potential for open pit mining which usually is cheap but have there been any estimates?

Would it be reasonable to say anything under $0.20 would be a good entry position for the ordinary shares?

Do many own the options?

Interest to hear your thoughts!
