Last I checked, the entity known as "Matrixx Resource Holdings, Inc." was non-existent as a Delaware corporation because its corporate status had lapsed in 2008, so your shares are meaningless/worthless in my opinion/estimation.
To get an actual and up-to-date answer, you would need to contact a Delaware lawyer for the question of what value/rights if any a "shareholder" has in a lapsed corporation, and you would need to confirm with the Delaware Secretary of State the current status of the entity. Assuming it were still void, it might nonetheless be theoretically possible to revive the entity's corporate status (that's a question for your Delaware lawyer), and maybe the "officers" here intended to do so if they struck oil, but my opinion is that shares here are worthless and have been since 2008.
All that said, my information dates back to 2012, so I could not tell you what's going on currently.
Out of curiosity, how many shares do you have, what did you pay for them, and when?
