Only 7 out of 3300 companies in the last decade or so have not been revoked. Do you really think a company that is run so horribly as SFEG will have everything necessary for the SEC to say "yes, things were so bad for you that it took over 2 years to get your financials done. Here is the golden key to start trading again as a respectable company that the public can trust!"
That is not happening. As you can see on the grey markets there are no trades. SFEG will be over in the coming weeks and the shares you hold will be worth $0. Now, that does not mean that the assets are going away. SFEG may be ever so kind to open as a new company and give shareholders equal shares in the new company. Good luck on that. This could have been their play all along. Delay everything, let the SEC end the company, and then open as new with no shareholders. Buried in the Financials, a lot of the land/mining rights are held by Mueller's private company.
In the end, it is very simple. Count the number of your shares multiply it by $0.00 and that is the value of the stock you now hold.
