Precious metals, PGM & REM, verified at the source.
Mox Core sources, assays, and trades gold, silver, platinum-group metals, rare earth metals, and advanced copper materials for corporations that need a single, verifiable point of contact — from raw material to certified report.
Mox Core × Helio Corporation
Mox Core stands as a strategic corporate partner to Helio Corporation (OTC: HLEO) — serving as a lead sales representative, working closely with Ed Cabrera, Chairman & CEO of Helio and Managing Director of Investment Banking at Network 1 Financial Securities, on energy, metal, and processing deals connecting South America and Helio.
One lab, the full range of precious metals, PGMs & REMs.
Every material that passes through Mox Core is measured, not assumed. Below is a working sample of the groups we source, assay, and trade for corporate clients — each figure is a grade we can verify on our own bench.
Select any element to see typical uses and request an assay.
A single desk for sourcing, verification, and trade.
Corporations working across borders and refiners don't need another broker — they need one counterparty who can source the material, prove what it is, and move it. That is the entire premise of Mox Core.
Sourcing & procurement
We identify and qualify supply of precious metals, PGM, and REM group material from vetted origin points, structured around each client's volume, grade, and delivery requirements.
In-house laboratory assay
Material is verified on our own bench in Miami before it moves — purity grade, particle characterization, and a certificate of analysis clients can hand to their own buyers.
Trading & delivery
Once verified, Mox Core structures the trade, logistics, and delivery terms directly with the corporation — one contact for the material and the paperwork behind it.
From origin to certified delivery, on one line.
Every lot follows the same path: sourced from a qualified origin, verified in our laboratory, then delivered with its documentation.
Beyond bullion: engineered copper nanomaterials.
Our lab also produces and characterizes high-purity copper nanopowder across the 5N (99.999%) to 7N (99.99999%) range, with particle populations confirmed by Nanoparticle Tracking Analysis (NTA) — the same instrumentation used to verify sub-micron particle size and concentration for electronics, catalysis, and advanced coatings clients.
It's the same discipline we apply to bullion, pointed at a newer class of material.
What a one-stop shop actually removes from your process.
Fewer counterparties
One relationship covers sourcing, assay, and trade — instead of coordinating brokers, independent labs, and traders separately.
Verifiable documentation
Every lot leaves with lab-backed purity data and a certificate of analysis your own compliance team can review.
Direct ownership
Mox Core is owned and operated by its three founding partners — decisions on your account are made by the people who own the company.
