You said "I suppose the only positive concerning the potential loss of the PDF is the fact that we can record our losses as a tax write off." Yes, that is true, but the problem I foresee is, how do you sell? If the PDF status is a condition of ASX reinstatement, then according to the ASX, MMR will not re-list if the PDF status is not returned. For example, in the Preliminary Final Report (01/09/2021) it says: "... on 22 June 2021 the Company made an announcement to market indicating that the ASX had advised that "Should Advent be successful in the extension of its PEP11 oil and gas exploration lease and MEC be successful in its appeal to reinstate its status as a PDF, ASX could consider conditions for reinstatement on the basis of continuation of MEC's existing business". " -ASX:MMR Preliminary Final Report (01/09/2021)

If I had shares, I would be asking my broker if there were any other means.
