GreenMet

GreenMet's compensation for brokering the CRML-Tanbreez partnership is absent from all public filings ⁷⁸. A comprehensive review of all 167 CRML SEC filings -- including 20-F annual reports, 6-K current reports, F-3 registration statements, Form 144 insider sales, and Schedule 13D/G beneficial ownership filings -- returned zero results for "GreenMet," "Sorial," "Schiller," or "Horn" ⁷⁸¹⁴. Tanbreez ownership is divided 92.5% CRML and 7.5% European Lithium, accounting for 100% of equity and leaving no room for a direct GreenMet stake in the Greenlandic entity ⁹.

Cross-referencing this absence with GreenMet's prior deals and corporate structure yields four plausible compensation vectors ⁹. First, a success fee from Rimbal Pty Ltd, the Australian private company controlled by Gregory Barnes that sold its Tanbreez stake to CRML ⁹: Rimbal received approximately $14 million from selling 2 million CRML shares in the October 2025 PIPE, and a referral fee paid by an Australian private company to a U.S. private company would be invisible to SEC disclosure ⁹. Second, an advisory fee from Cantor Fitzgerald, which served as CRML's SPAC underwriter and with which GreenMet works on Tanbreez project finance; a fee arrangement between GreenMet and Cantor would not require CRML disclosure ⁴⁹. Third, consulting fees structured below SEC materiality thresholds ⁹. Fourth, deferred equity or warrants tied to milestones such as EXIM loan closing or Stage 2 completion that have not yet triggered disclosure ⁹.

GreenMet's proven business model from prior deals supports the equity-for-services hypothesis. In November 2021, Greentech Minerals Holdings signed a Financing and Purchase Option Agreement with Texas Mineral Resources Corp. (TMRC), committing to fund a $6.5 million bankable feasibility study for TMRC's Black Hawk Mining District silver project in New Mexico in exchange for 20.2% equity in a proposed TMRC-Santa Fe Gold joint venture ¹⁵¹⁶. GreenMet subsequently determined not to pursue the financing option per TMRC's SEC filing, abandoning the deal ¹⁵. The TMRC arrangement demonstrates that equity-for-services is GreenMet's established deal structure ¹⁶.

GreenMet also operates as a capital-raising intermediary. According to ION Analytics reporting, GreenMet helped secure a $50 million Cerberus Capital Management investment in Torngat Metals for the Strange Lake rare earth project in Canada in November 2022 ⁴. Horn described GreenMet's role as "a facilitator" and stated the company "helped identify and develop the investment opportunity" ⁴. In this model, compensation is typically a percentage of capital raised, structured through private arrangements that carry no public filing requirements ⁴.

Washington, DC, corporate registry documents identify three beneficial owners of GreenMet: Drew Horn (CEO), George Sorial, and Keith Schiller ³. Horn is a former Army Special Forces and Marine Corps officer who served as an aide to Vice President Pence, a national security official at the Department of Energy, and a Senior Advisor at the Office of the Director of National Intelligence before founding GreenMet ². Sorial served as the Trump Organization's Executive Vice President and Chief Compliance Counsel for approximately seventeen years (2002-2019), while Schiller was Donald Trump's personal bodyguard for decades before serving as Director of Oval Office Operations in the first Trump administration ². Sorial stated that he and Schiller are "passive minority shareholders in GreenMet and have no management role in the company," having resigned board and advisory roles in early 2025 ³.

The Libra Group, an international business conglomerate led by CEO George Logothetis with subsidiaries spanning energy, shipping, real estate, and hospitality across more than 50 countries, holds a 44% minority stake in GreenMet following a March 2022 strategic investment, with four Libra executive team members appointed to the GreenMet board ⁴⁵. This investment provided GreenMet with capital and board-level international business connections beyond its Washington policy network.

Ned Mamula served as GreenMet's Chief Geologist before being confirmed as Director of the U.S. Geological Survey in October 2025 ¹¹. Mamula is a former CIA geoscientist whose career spanned USGS, DOE, CIA, and the Cato Institute ¹¹. Horn co-authored the foreword to Mamula's 2024 book according to OCCRP reporting ¹¹. Mamula filed a divestiture from GreenMet in January 2026 following his confirmation, but the USGS directorship gives him authority over the Critical Minerals List -- a designation directly relevant to GreenMet's business interests ¹¹.

GreenMet's advisory work extends well beyond the CRML-Tanbreez deal. Three additional client relationships have been confirmed ¹⁰. Horn presented at a NioCorp Developments (NASDAQ: NB) webcast for the Elk Creek Critical Minerals Project on April 29, 2025, and GreenMet appears in NioCorp's EDGAR filings ¹⁰. GreenMet also entered a strategic advisory alliance with US Critical Materials Corp to support federal funding for gallium and critical mineral production ¹⁰. And in November 2022, GreenMet helped secure a $50 million Cerberus Capital Management investment in Torngat Metals for the Strange Lake rare earth project in Canada ⁴.

The NioCorp relationship is particularly notable because Javelin Advisors (Sorial/Schiller) also lobbies for NioCorp, creating a coordinated advisory ecosystem where the same principals service the same client through parallel entities ¹⁰. This pattern -- Horn as minerals advisor through GreenMet, Sorial and Schiller as government relations consultants through Javelin -- replicates across the critical minerals sector ¹⁰. Both firms draw on the same network of former Trump administration officials and defense connections, but operate as separate legal entities with distinct disclosure obligations ¹⁰.

In December 2024, Sorial, Schiller, and attorney Robert W. Seiden formed Javelin Advisors LLC in Delaware ². On April 25, 2025, Javelin registered under FARA (Registration No. 7579) as a foreign agent for Pakistan to pursue a rare earth minerals agreement with the United States, receiving $50,000 per month through Seiden Law LLP ². FARA filings reference a May 2025 framework for U.S.-Pakistan cooperation on rare earth minerals with an indicative value of up to $1 trillion, with Pakistan's Frontier Works Organisation nominated as the extraction entity ². Javelin used Rep. Ronny Jackson as its primary congressional contact, arranging meetings that led to a draft memorandum of understanding delivered to the office of Rep. Ryan Zinke and a reported $30 million deal between US Strategic Metals and Pakistan's Frontier Works Organisation in September 2025 ².

GreenMet's principal deal-making centers on Greenland. In April 2025, GreenMet partnered with Tanbreez Mining Greenland A/S, which holds what it describes as the only shovel-ready rare earth project in Greenland, with a 4.7-billion-tonne deposit containing 27% heavy rare earth elements ⁶. GreenMet brokered a partnership between Critical Metals Corp (NASDAQ: CRML) and Tanbreez, under which Critical Metals acquired a 92.5% stake from Rimbal Pty Ltd, with European Lithium retaining the remaining 7.5% ⁶⁹. By September 2025, Critical Metals had taken a controlling interest in Tanbreez ¹¹.

GreenMet also facilitated U.S. government financial backing for the deal. The EXIM Bank issued a $120 million letter of interest for a 15-year term loan under its Supply Chain Resiliency Initiative ⁶. Separately, GreenMet brokered a 10-year offtake agreement between Critical Metals and Ucore Rare Metals for up to 10,000 tonnes per year of rare earth concentrates to be processed at Ucore's DoD-funded Strategic Metals Complex in Louisiana ⁶. A preliminary economic assessment of the Tanbreez deposit projected a net present value of $3.04 billion and an internal rate of return of 180% ⁶. GreenMet works with Cantor Fitzgerald on Tanbreez project finance, and is soliciting investors for approximately $211 million needed for scaling production, infrastructure, and hydropower ⁴.

GreenMet's Greenland ambitions extend beyond minerals into AI infrastructure. According to media reports, AmForge Corporation (CEO Dan Whaley) signed a letter of intent with Svend Hardenberg's Inuit Development Company ApS for a 1.5-gigawatt AI data center at Kangerlussuaq, Greenland, with GreenMet serving as matchmaker and ongoing advisor ¹⁷. The project envisions 300 megawatts by mid-2027, scaling to 1.5 gigawatts by end of 2028 ¹⁷. Horn described the division of labor: "He handles everything related to Greenland and Denmark, I handle everything related to the United States" ¹⁷. However, the Greenland government told CNBC that it has not engaged in dialogue with Horn or GreenMet about the project, and no land or local approvals have been secured ¹⁷.

Greentech Minerals Holdings Inc. was incorporated in Delaware on April 9, 2021, and registered in Washington, DC, at 1825 K Street NW, Suite 515 ¹. The company is registered in SAM.gov under UEI ZD31U1MMR4J7 and CAGE code 9VEL9, with primary NAICS code 551114 (Corporate, Subsidiary, and Regional Managing Offices) and a purpose code of Z2 (federal assistance) ¹.

GreenMet organized itself into four legal entities ¹⁸¹⁹. The parent company, Greentech Minerals Holdings Inc., sits atop three branded divisions: GreenMet Advisory (GreenMet Consulting LLC, DC Foreign LLC C00007696390, now withdrawn), which handled policy and business strategy consulting; GreenMet Capital (GreenMet Real Asset Management LLC, DC Foreign LLC C00007684320, also withdrawn), described as connecting critical mineral projects with "tailored investment solutions" and facilitating project funding; and GreenMet Innovation (GreenMet Technologies LLC), which does not appear in any searched corporate registry across DC, Florida, New York, or Delaware ¹⁸¹⁹. The GreenMet Capital entity performed precisely the function GreenMet carried out for the Tanbreez deal -- connecting projects with investment capital ¹⁸. The withdrawal of both registered DC subsidiaries removes them from ongoing DC filing and disclosure requirements ¹⁸.

Analysis of 37 LDA filings shows GreenMet's lobbying activity evolved through four phases ¹³. Phase one (Q2-Q4 2021) used Strategies 360 with lobbyist Ami Sanchez at $10,000 ¹³. Phase two (Q4 2021-Q3 2023) engaged the McKeon Group Inc., headed by former House Armed Services Committee Chairman Howard "Buck" McKeon, generating approximately $269,500 in disclosed income across 20 filings ¹²²⁰. Phase three (Q2 2023-Q2 2024) expanded to an in-house team of six lobbyists covering NDAA provisions, Defense Production Act, critical mineral appropriations, IRA magnet tax credits, and national lab R&D ¹³. Phase four (Q3 2024-present) contracted to a sole lobbyist, Sabrina Katz, covering defense, energy, manufacturing, natural resources, and trade/tariff issues ¹³.

GreenMet targeted a broad range of government entities: DOD, DOE, DOS, OSTP, Commerce, DLA, NSC, EOP, Treasury, and USTDA ¹². Cogent Strategies overlapped during phase three, adding $20,000 ¹³. According to biographical records, the Cogent lobbyist assigned to GreenMet was Andrew Kauders, a former senior adviser to Senator Robert Menendez (later convicted of bribery), who came to Cogent via the Podesta Group ²¹.

The McKeon Group also lobbied for USA Rare Earth, connecting two critical minerals companies in the investigation through a common defense-focused lobbying firm ²². According to congressional records and LDA filings, Nicole Rodgers, GreenMet's former Chief Government and External Affairs Officer (Q3 2023-Q2 2024), founded the Alliance for Mineral Security, a national coalition advocating for U.S. mineral independence, testified before Congress on critical minerals, and later joined Squire Patton Boggs ²³.
