Hi badge,
it is more easy as you think, the Company Petaquilla is - if the mine is open - the carrier of the mine because they have the license for exploitation than (in this case from Panama Government), so they can also give this license to an sub-Corporation for example. The owner of Petaquilla shares stay as owner. Petaquilla shares are currently not tradeable, only out of stock market. But if Petaquilla rise of ash..., the shares are will be back very soon on stage! Because Petaquilla and his biggest sharehoulders, for sure will come back on normal stock market! That is the pressure of big Money.
