The global transition to renewable energy and sustainable agriculture has created unprecedented demand for critical minerals, driving innovative companies to explore previously untapped resources. Odyssey Marine Exploration (OMEX) is a publicly traded company with over 30 years of deep ocean experience. Over the years, the company has successfully pivoted from historic shipwreck recovery to modern seafloor mineral extraction, positioning itself as a first-mover in an emerging industry valued in the billions.
From Shipwrecks to Seafloor Minerals
Odyssey's unique competitive advantage stems from three decades of deep ocean operations experience. CEO Mark Gordon explains,
"We learned how to use complicated equipment in the deep ocean, how to execute difficult projects in difficult environments."
This operational expertise, originally developed for recovering valuable cargos from historic shipwrecks beyond 1,000 feet water depth, translates directly to mineral extraction.
"Sometimes I say simply by changing out the science team on the boat, moving from archaeologists during the shipwreck business to geologists now, almost everything else is the same - the sophisticated sonar systems, the remotely operated submarines, the ships."
The company's exploration methodology mirrors traditional mining practices, beginning with desk-based research to identify optimal locations, followed by precise target identification and deep-water recovery operations. This systematic approach has enabled Odyssey to build a diversified portfolio of mineral assets across multiple jurisdictions, focusing exclusively on exclusive economic zones within 200 nautical miles of sovereign nations rather than international waters.
Strategic Focus on Critical Minerals
Odyssey has strategically concentrated on two essential mineral categories addressing fundamental human needs.
"Any mineral available on dry land will be available in the ocean. [But the company has] decided to focus on things that are important for mankind and in relatively short supply right now."
The first focus area is phosphate, a critical fertilizer component that cannot be laboratory-created and must be sourced from nature. The second emphasis targets battery metals for electrification, specifically polymetallic nodules containing cobalt, copper, and rare earth elements essential for renewable energy infrastructure.
This strategic positioning addresses supply chain vulnerabilities in both food security and energy transition. Mexico currently imports over 50% of its phosphate requirements, while global battery metal demand continues outpacing traditional mining capacity. Odyssey's projects could potentially transform these supply dynamics while generating substantial revenues for stakeholders.
Mexico Phosphate Project: Near-Term Production Potential
The company's most advanced asset, located off Mexico's Pacific coast, contains a quantified phosphate resource valued in the billions under a 43-101 standard. The project has progressed through pre feasibility studies and requires only final environmental approval for production commencement.
"Mexico right now imports ... let's call it more than 50% of the raw phosphate rock phosphate they need for their fertilizer business. They could turn that country into a net exporter almost instantly with this project."
Recent political developments have improved the project's prospects significantly. The previous administration's permit denial was overturned by Mexico's highest court in 2018, with an 11-judge panel ruling unanimously that the government acted unlawfully. Subsequently, Odyssey prevailed in NAFTA arbitration proceedings, though the $60 million damage award was lower than anticipated, causing temporary share price volatility in September.
The new Sheinbaum administration's science-based approach and mining-friendly policies create optimism for Odyssey's project advancement. Gordon formed a strategic joint venture with Juan Cortina Gallardo, a respected agribusiness leader representing 80% of Mexico's agricultural GDP through the CNA farmers' association. This partnership brings essential local expertise and political connectivity. Underscoring its importance, Odyssey recently announced a $4 million financing through a securities purchase agreement, led by Mr. Cortina, holders of Odyssey’s debt, and the company’s lead director
Production Economics and Infrastructure Advantages
The Mexico project's economic fundamentals appear robust, with rock phosphate currently priced around $150 per ton and planned annual production of three million tons generating several hundred million dollars in revenue. Gordon projects "at least a 30% gross margin in those revenues" due to operational efficiencies and partnership with Royal Boskalis, one of the world's largest dredging companies, eliminating significant capital expenditure requirements.
The partnership structure optimizes each party's core competencies. Odyssey handles exploration, quantification, and extraction using modified existing dredge ships, while Mexico's state-owned PEMEX fertilizer division manages processing and distribution through established infrastructure.
"We don't have any designs on building new fertilizer plants and trying to figure all that out. That's not our core competency, but we can deliver the raw product to the beach."
Interview with CEO Mark Gordon
Cook Islands: Strategic Polymetallic Nodule Investments
Odyssey's Cook Islands strategy involves minority stakes in two exploration companies holding licenses for cobalt-rich polymetallic nodules. The company owns approximately 6% of OML (Offshore Minerals Limited), which has completed a JORC resource estimate valuing their holdings at $4.7 billion, and 15% of CIC (Cook Islands Consortium), whose license area is ten times larger than OML's territory.
These investments provide exposure to battery metals without requiring direct operational management or significant capital investment.
"We provide services to both those operators. One of our forms of contribution to get our equity stake in OML was putting one of Odyssey's 6,000 meter rated remotely operated vehicles aboard their ship that's doing the exploration work."
The Cook Islands government has maintained stable, development-friendly policies for several years, positioning the territory as an attractive jurisdiction for seafloor mining operations. Both companies have progressed through three years of exploration programs and completed extensive environmental assessments, with trial extraction licenses potentially forthcoming within 6-12 months.
Regulatory Environment and Recent Catalysts
The regulatory landscape for seafloor mining has improved significantly, particularly following President Trump's recent executive order supporting domestic mineral production. Gordon observes,
"I think that the executive order issued by President Trump several weeks ago is an indication that the US is getting very engaged and looking at refining their regulatory framework to accommodate it."
This policy shift could unlock additional opportunities in US territorial waters, where Odyssey has maintained qualified bidder status with the Bureau of Energy Management since 2021. Odyssey's exclusive focus on territorial waters rather than international waters simplifies regulatory compliance by dealing with individual sovereign nations rather than complex multinational frameworks.
"It's hard enough to deal with one government to get the regulatory approvals you mentioned earlier. And for us it was pretty daunting to think about getting 160 odd countries in the United Nations to give us a regulatory framework."
Financial Position and Funding Strategy
Following recent warrant and option exercises generating $2 million, plus the $4 million December financing round, Odyssey maintains adequate liquidity for near-term operations. The company's cash burn remains relatively fixed, primarily covering public company compliance costs while minimizing exploration expenditures until regulatory clarity improves.
Future funding requirements will be addressed through project-specific financing rather than dilutive equity raises. Major capital expenditures for the Mexico project will occur at the joint venture level, while partnerships with established operators like Royal Boskalis reduce infrastructure investment needs.
"Elements of debt or project specific financing are ways we'll be able to finance capital needs without additional dilutive impact."
Near-Term Catalysts and Timeline
Gordon anticipates significant news flow within 30-90 days regarding Mexico project discussions, while Cook Islands developments may materialize within 6-12 months. The regulatory momentum from both the Trump administration's executive order and Mexico's new government creates favorable conditions for project advancement.
"I think we're at that inflection point finally now," Gordon observes, comparing the current moment to offshore oil and gas development in the 1970s, when technological capability existed but required regulatory and political catalysts for widespread adoption. The combination of critical mineral shortages, technological feasibility, and improving regulatory frameworks suggests seafloor mining may be approaching commercial viability.

Macro Thematic Analysis
The global transition to sustainable energy and food security faces a fundamental constraint: terrestrial mineral resources are increasingly depleted after millennia of extraction. As Gordon notes,
"the critical minerals mankind is going to need into the future has to come from the 70% of our earth that's underwater because the 30% of the dry surface has been pretty exhausted after 2,000 years of mankind harvesting from the dry surface."
This resource scarcity coincides with unprecedented demand growth driven by electrification and population expansion, creating a compelling macro environment for seafloor mining development. The ocean floor contains vast deposits of polymetallic nodules rich in cobalt, nickel, and copper essential for batteries, while phosphate deposits could address global food security concerns as traditional agricultural inputs become constrained.
Recent regulatory developments, including the Trump administration's mining-friendly executive order and Mexico's science-based policy approach, signal growing governmental recognition that seafloor resources represent a strategic necessity rather than an environmental luxury.
