Green Minerals

What Green Minerals does

Green Minerals AS is a pre-commercial Norwegian deep sea mining explorer founded in 2020 and listed on Euronext Growth Oslo since March 2021 under the ticker GEM (ISIN: NO0010907744), headquartered at Olav Selvaags plass 5, Oslo. The company is pioneering marine mineral extraction on the Norwegian Continental Shelf, targeting polymetallic nodules, seafloor massive sulfide ores, copper, manganese, cobalt, nickel, and rare earth elements needed for the green transition. Its core technology proposition centers on responsible deep-sea mining systems with environmental footprint reduction of over 90% versus onshore mining (citing Paulikas et al., 2020), ore grades 4-10x higher than typical new terrestrial mines, and an estimated 38 mT copper in-situ resource potential on the NCS. The company has completed a conceptual study with an Oil States Industries-led consortium for a Harsh Environment Deep Sea Mining System tailored to Norwegian waters and maintains research partnerships with the University of Southampton, NTNU, and the University of Bergen.

The business model is pre-revenue with no commercial extraction or off-take contracts in place; the hardware_sales revenue stream is forward-looking and pricing is not publicly disclosed. GTM is focused on investor relations, regulatory engagement with Norwegian authorities, and partnership development with academia and offshore industry clusters (Offshore Norge, Norwegian Forum for Marine Minerals, GCE Ocean Technology) to position for future licensing rounds. In June 2025, the company adopted a Bitcoin Treasury Strategy funded by a NOK 250 million structured financing agreement with LDA Capital (closed July 2025), representing a non-core treasury diversification. Target customer segments — Clean Energy/EV Manufacturers and European/US Strategic Mineral Buyers — are horizontal and prospective rather than contracted. The company's near-term trajectory is contingent on the Norwegian government's implementation of continental shelf opening for seabed minerals, a delay in which triggered a strategic review announcement in December 2025 alongside the announced departure of CEO Øivind Dahl-Stamnes effective January 1, 2026.

Direct peers

• The Metals Company: The Metals Company is the leading publicly listed deep sea mineral explorer focused on polymetallic nodules in the Clarion-Clipperton Zone. Like Green Minerals, it is pre-revenue, pursuing offshore extraction of battery and electrification metals, and is exposed to similar ESG, regulatory, and capital markets dynamics.
• Allseas: Allseas is a Dutch offshore contractor developing the Hidden Gem deep sea mining vessel and collection system for polymetallic nodule harvesting. Its engineering-led approach to deep sea mineral collection overlaps with Green Minerals' Oil States Industries partnership for harsh-environment extraction systems.
• Loke Marine Minerals: Loke Marine Minerals is a Norwegian exploration company also targeting seabed minerals on the Norwegian Continental Shelf with a focus on manganese crusts. It is a direct domestic peer competing for the same Norwegian licensing rounds as Green Minerals.

Emerging players

• Impossible Mining: Impossible Mining is a US-based early-stage company developing robotic deep sea mineral collection technology targeting polymetallic nodules. It is a comparable emerging player focused on offshore critical minerals extraction with a sustainability-led positioning.
• Energy Transition Minerals: Energy Transition Minerals (formerly GTK Finland-affiliated, Greenland-focused) is pursuing rare earth and critical mineral projects with similar EU/US strategic mineral supply narratives. Its focus on Western-aligned critical mineral supply parallels Green Minerals' EU/US offtake story.
• Cobalt Blue Holdings: Cobalt Blue Holdings is an Australian-listed critical minerals company developing cobalt and battery materials projects. While onshore-focused, it pursues the same EV/battery supply chain narrative targeting EU/US strategic mineral demand that drives Green Minerals' thesis.

Regional players

• Blue Minerals Jamaica: Blue Minerals Jamaica is a Jamaica-registered deep sea mineral exploration company focused on the Clarion-Clipperton Zone via a Jamaican sponsorship. It is a comparable early-stage player pursuing offshore polymetallic nodule resources but operating in a different Atlantic jurisdiction than Green Minerals.
• Cook Islands Investment Corporation: The Cook Islands Investment Corporation, through CIIC Seabed Resources, is a Pacific-based state actor exploring seabed mineral resources. It is comparable as a regional public-sector deep sea exploration entity but does not directly compete in the Norwegian Continental Shelf.
• Marawa Research and Exploration: Marawa Research and Exploration is a Kiribati state-sponsored entity exploring seabed minerals in Pacific waters. It is comparable as a regional state-affiliated deep sea exploration entity but operates in a different ocean jurisdiction than Green Minerals' Norwegian Continental Shelf focus.

Broad incumbents

• Aker BioMarine: Aker BioMarine is a Norwegian-listed marine resources company with offshore operations expertise, ecosystem interest in marine minerals, and connection to the broader Aker industrial group. While not a deep sea miner, it is a comparable Norwegian-listed marine resource operator with adjacent interest in seabed minerals.
