Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	NOTE P – COMMITMENTS AND CONTINGENCIES Rights to Future Revenues, If Any We have sold the rights to share in future revenues, if any, with respect to the “Seattle” and the “Cambridge” (“HMS Sussex”) projects and have recorded $887,500 as Deferred Income from Revenue Participation Rights (See NOTE L). We are contingently liable to share the future revenue of these projects only if revenue is derived from these specific projects. To date, the only income derived from these projects resulted in a one-time revenue distribution payment of $12,986 to the holders of the “Cambridge” RPC’s. In addition, on May 26, 1998, we signed an agreement with a subcontractor that entitled it to receive 5% of the post finance cost proceeds from any shipwrecks in a predefined search area of the Mediterranean Sea. A shipwreck we have found, which we believe to be HMS Sussex, is located within the specified search area and we will be responsible to share future revenues, if any, from this shipwreck. On December 9, 2002, a Georgia limited liability company acquired the 5% interest from the subcontractor through a foreclosure sale (see NOTE K). In February 2011, we entered into a project syndication deal with Galt Resources LLC (“Galt”) for which they invested $7,512,500 representing rights to future revenues of any project of Galt’s choosing. This amount has been bifurcated equally between the SS Gairsoppa and HMS Victory projects. The SS Gairsoppa has been paid in full. See NOTE L for further detail. Legal Proceedings The Company may be subject to a variety of other claims and suits that arise from time to time in the ordinary course of business. We are currently not a party to any pending litigation. Contingency During March 2016, our Board of Directors approved the grant and issuance of 3.0 million new equity shares of Oceanica Resources, S.R.L. to two attorneys for their future services. This equity is only issuable upon the Mexican’s government issuance of the Environmental Impact Assessment (“EIA”) for our Mexican subsidiary. This grant of new shares was also approved by the Administrators of Oceanica Resources, S.R.L. We also owe consultants contingent success fees of up to $425,000 upon the approval and issuance of the EIA. The EIA has not been issued as of the date of this report. Going Concern Consideration We have experienced several years of net losses and may continue to do so. Our ability to generate net income or positive cash flows for the following twelve months is dependent upon our success in developing and monetizing our interests in mineral exploration entities, generating income from exploration charters, collecting on amounts owed to us, and completing the MINOSA/Penelope equity financing transaction approved by our stockholders on June 9, 2015. Our 2018 business plan requires us to generate new cash inflows to effectively allow us to perform our planned projects. We plan to generate new cash inflows through the monetization of our receivables and equity stakes in seabed mineral companies, financings, syndications or other partnership opportunities. If cash inflow is not sufficient to meet our desired projected business plan requirements, we will be required to follow a contingency business plan which is based on curtailed expenses and fewer cash requirements. On March 11, 2015, we entered into a Stock Purchase Agreement with Minera del Norte S.A. de c.v. (“MINOSA”) and Penelope Mining LLC (“Penelope”), an affiliate of MINOSA, pursuant to which (a) MINOSA agreed to extend short-term, debt financing to Odyssey of up to $14.75 million, and (b) Penelope agreed to invest up to $101 million over three years in convertible preferred stock of Odyssey. The equity financing is subject to the satisfaction of certain conditions, including the approval of our stockholders which occurred on June 9, 2015, and MINOSA and Penelope are currently under no obligation to make the preferred share equity investments. (See Item 7, Management’s Discussion and Analysis of Financial Condition and Results of Operations—Financings.) Our consolidated non-restricted cash balance at December 31, 2017 was $1.1 million which is insufficient to support operations for the following 12 months. We have a working capital deficit at December 31, 2017 of $31.5 million. Our largest loan of $14.75 million from MINOSA had a due date of December 31, 2017 which is now linked to other stipulations, see NOTE I for further detail. The majority of our remaining assets have been pledged to MINOSA, and its affiliates, and to Monaco Financial LLC, leaving us with few opportunities to raise additional funds from our balance sheet. The total consolidated book value of our assets was approximately $3.0 million at December 31, 2017 and the fair market value of these assets may differ from their net carrying book value. Even though we executed the above noted financing arrangement with Penelope, Penelope must purchase the shares for us to be able to complete the equity component of the transaction. The Penelope equity transaction is heavily dependent on the outcome of our subsidiary’s application approval process for an environmental permit to commercially develop a mineralized phosphate deposit off the coast of Mexico. The factors noted above raise doubt about our ability to continue as a going concern. These consolidated financial statements do not include any adjustments to the amounts and classification of assets and liabilities that may be necessary should we be unable to continue as a going concern.
