The Portfolio · Current & Former

Named in the room. Described here.

Every engagement below is real. Descriptions give the general location and the technology or material — nothing more. Specific names, scopes, and references are furnished under executed NDA.

Workflow

How an engagement runs.

One connected motion — the same six stages, whether the mandate is a filing, a campaign, or a supply chain.

IAccess

Direct, durable reach across the national-security and finance interagency — built over years, not rented for a deal.

IIDiplomacy

The standing to engage sovereign and host-government partners, and convert it into material and market access.

IIICapital

Sovereign and institutional capital formed around assets structured to be financeable.

IVAdvisory

Positioning government-vetted developers into the shape that agencies and lenders can say yes to.

VSupply Chain

Building the routes — mine, processor, logistics, end user — that hold under scrutiny.

VIExecution

Moving material and capital through the regulatory and political environment. Cleanly.

Current Clients

The active book.

Eleven current client engagements across critical minerals, nuclear fuel, advanced materials, energy, and policy. Locations are given at the state or national level; technologies and materials as publicly characterized.

01

Tungsten developer

The largest undeveloped tungsten resource in America — federal positioning and agency-engagement strategy, sequenced deliberately toward development of the deposit the defense industrial base will eventually need.

███████████Nevada · USACritical Minerals
02

Uranium developer

A portfolio of past-producing American uranium mines advanced as a brownfield restart — framed against the fuel-security mandate created when adversary imports were banned.

██████████Western USANuclear Fuel
03

Polymetallic silver developer

Silver with its strategic weight in the by-products — antimony and gallium, the materials under adversary export controls — framed for the audiences where that urgency lives.

████████Alaska · USACritical Minerals
04

Cobalt-nickel-copper producer & recycler

Domestic battery-metals mining, recycling, and hydrometallurgical refining — positioned across the federal financing, stockpile, and offtake landscape.

█████████████Missouri · USABattery Metals
05

Solid-state metals technology company

Electrochemical reduction of oxides directly to titanium, tantalum, and alloy powders — allied additive-manufacturing feedstock, positioned into U.S. defense programs.

██████████United KingdomAdvanced Materials
06

Phosphate-processing technology company

Cleaner phosphoric-acid production with critical-mineral recovery from phosphate streams — fertilizer security and by-product rare earths in a single thesis.

████████████Southeastern USAProcessing
07

Energy company

Advanced-energy programs built alongside a flagship state university — the research-to-deployment pathway, structured and carried toward federal customers.

█████████Texas · USAEnergy
08

Exploration & development holdings

District-scale ground in a historic American mining district — advanced with disciplined federal positioning and patient capital formation.

███████████Nevada · USAFrontier
09

Research universities & policy institutes

Critical-minerals research hubs, national-security data and policy institutes, and standing advisory roles — the working positions where the rules of the materials age are written.

██████████Virginia · N. Carolina · TexasPolicy

Counting related entities and university programs, the current book stands at eleven engagements. The named record — entities, scopes, and references — is furnished under executed NDA.

Former & Completed

Mandates carried to conclusion.
