Why MTL Vault Exists
Existing public products for rare earth and specialty metals primarily hold mining equities. MTL Vault is built to hold the physical material itself, on U.S. soil.
01

The Demand Is Real

Governments worldwide have designated these materials as strategically critical. EV makers, defense contractors, and semiconductor fabs compete intensely for limited supply.

02

The Existing Products Are Indirect

Mining equities carry company-specific risk, dilution, permits, hedging, geopolitics. A miner can underperform even when the metal it digs appreciates substantially.

03

Direct Physical Exposure Has Been Missing

Public markets offer no physically backed trust holding a basket of rare earth and specialty metals. MTL Vault is designed to address that gap through a passive, physically backed structure built for direct ownership.

Miners vs. MTL Vault

Own the metal.
Not the noise around it.

Physical ownership strips away layers of corporate noise. Your exposure tracks the metal, not a management team's quarterly results.

Mining Equities / Critical Minerals ETFs
✕

Indirect exposure, you own stock in a company that mines, processes, or explores for metals.

✕

Production risk, missed guidance, operational delays, and mine permitting.

✕

Dilution risk, companies raise capital, eroding your share of value.

✕

Corporate hedging, many miners hedge commodity exposure, reducing upside.

✕

Country and jurisdiction risk, political instability in mining regions.

MTL Vault
✓

Direct physical ownership, each share is a beneficial interest in a trust that owns lot-identified metal.

✓

No producer risk, the trust buys processed material from merchants and counts it only once a U.S. warehouse has accepted it.

✓

No dilution, no hedging, a passive structure that holds the basket without trading it, with acquisition costs borne by new capital.

✓

Allocated U.S. inventory, every lot carries its own ID and warehouse receipt, physically separated from other material.

✓

Independent NAV, calculated by a third-party administrator from published price assessments and independent dealer quotes.

Basket
Three metals at launch, six at scale

NdPr oxide, tungsten APT, and gallium at launch. Germanium, antimony, and indium are added as assets grow.

Custody
Allocated U.S. warehouse inventory

Metal is recognized only after receipt, acceptance, a warehouse receipt, and lot-level allocation.

Valuation
Independent, auditable NAV

Price-reporting agency assessments, U.S.-delivered where published, supported by independent dealer quotes.

Access
Private phase, Rule 506(c)

For verified accredited investors. A public listing remains an option, not a requirement.

The Six-Metal Basket

Three industries.
Six essential materials.

The basket spans three strategic industries: electrification and clean energy, defense and industrial, and semiconductors and advanced electronics. MTL Vault launches with one metal from each and is designed to add three more as assets grow, subject to dealer capacity and the final tax structure.

Weights are sized to what each market can absorb. The deepest markets carry most of the portfolio, the scarcest metals are capped in tonnes, and no metal is sold simply to rebalance. All six appear on the USGS Final 2025 List of Critical Minerals.

How It Works

Simple by design.
Serious in structure.

01

MTL Vault Acquires Physical Metal

The trust buys lots matched to published benchmark specifications through established metals merchants, pacing purchases to what each market can absorb. Metal enters the trust only after physical receipt and formal acceptance at an approved U.S. warehouse.

02

Metal Is Held in Allocated U.S. Inventory

Every lot carries a unique identifier and a warehouse receipt, and is physically separated from other customers' material rather than commingled in a pool. Warehousing is planned for Baltimore and the Los Angeles basin, with room to expand as assets grow.

03

Investors Hold Shares in the Trust

Each share represents a beneficial interest in the trust, which owns the metal on investors' behalf. NAV is calculated by an independent administrator through a methodology designed to be transparent, auditable, and repeatable.

A Note on Valuation

MTL Vault values its holdings under a written policy built on third-party evidence: price-reporting agency assessments, on a U.S.-delivered basis wherever one is published, supported by independent dealer quotes. The trust's administrator and auditor must approve that policy before any investor capital is accepted. Because the sponsor is paid on NAV, it cannot approve its own marks, and the trust's own purchases are never, on their own, used to value its holdings.

The Case for Physical

Why physical metal.
Why the structure matters.

Many investors want direct exposure to an underlying material without taking on the burden of sourcing, storing, insuring, and reconciling that asset themselves. MTL Vault is designed to provide that exposure through a passive, physically backed trust.

01 / Isolation

Own the Asset, Not the Business Around It

Physical metal ownership removes corporate risk from the equation. No management team to judge, no earnings call to parse, no dilution to model. Your exposure is to the material itself, and that is precisely the point.

02 / Geopolitical Relevance

Strategic Significance Beyond Returns

Supply chains for rare earths and critical metals are geographically concentrated, and since 2023 China has imposed export controls on gallium, germanium, antimony, and tungsten. Access to these materials has become a live subject of trade policy and national security planning. Physical ownership in U.S. warehouses carries both financial and strategic weight.

03 / Structural Discipline

Built to Be Legible and Auditable

Passive ownership, allocated custody, and independent valuation are not incidental details. They are the core of the structure.

04 / Neutrality

Access, Not a Forecast

MTL Vault does not take, market, or require a view on where these metals will trade. There has been no clean way to own them, and the trust is built to provide one. Investors bring their own view.

Trust Structure

Built for clarity,
custody, and auditability.

MTL Vault is designed as a physically backed, passive trust, not an operating company, not an actively managed commodity fund, and not a futures product. The objective is direct beneficial exposure to allocated metal through a structure that can be understood, administered, and audited.

How the Trust Operates

  • Available to verified accredited investors
  • General solicitation permitted under SEC Rule 506(c)
  • Delaware statutory trust; investors hold beneficial interests in the trust, which owns the metal
  • No leverage, derivatives, metal lending, or rehypothecation
  • New subscriptions bear their own acquisition costs, so existing investors do not subsidize them
  • NAV calculated by an independent administrator, not the sponsor
  • Participation, lockup, and transfer terms will be set out in the private placement memorandum

Liquidity and the Public Option

  • Built for long-term holders; private liquidity is being designed around an initial lockup followed by limited periodic windows
  • The private trust is designed to stand on its own; no listing is promised
  • A U.S. exchange listing or successor public vehicle remains an option if economics and market structure justify it
  • A listing would add secondary-market liquidity for investors who want it
  • Any public phase would remain subject to counsel, exchange, and regulatory approval
Structural Discipline
Passive Design

No active trading, no futures, no leverage or metal lending, and no operating-company exposure. The structure is designed to hold metal, value metal, and report on metal.

Allocated Custody

Metal enters the trust only after receipt and acceptance at an approved U.S. warehouse, then remains identifiable by lot in allocated inventory rather than a general pool.

Independent Valuation

MTL Vault is not a metals merchant, and the sponsor does not calculate NAV. An independent administrator does, from third-party price evidence, under a policy the auditor approves before launch.

Metal markets can be illiquid and volatile. The trust's federal tax classification, investor tax reporting, and basket mechanics remain subject to a formal tax opinion. No public listing or successor public vehicle has been reviewed by the SEC or any national securities exchange, and there can be no assurance that one will be pursued or obtained. MTL Vault is not affiliated with or endorsed by any government program, including the U.S. government's Project Vault critical minerals stockpile. The trust is a privately sponsored vehicle and operates independently. Please review all offering documents carefully and consult your own legal, tax, and financial advisors before investing.
