How Gold Actually Reaches a Trading Desk: Industrial Mines, Artisanal Supply, and the Melt-and-Pay Safeguard.

Every gold offer a desk receives claims to come from a mine. Almost none of them explain which kind. That single distinction, industrial or artisanal, determines nearly everything else about whether the deal in front of you is real, whether the seller actually has the right to sell it, and what a safe transaction structure even looks like. This piece breaks down both supply chains from the ground up to the point a deal lands on your desk, then walks through melt-and-pay, the settlement structure that removes most of the fraud risk this site's Forensic Files pieces keep documenting.

Industrial Gold Mining: The Output Is Usually Already Spoken For

A large-scale, mechanized gold mine doesn't start selling gold the day it starts producing. It starts selling gold years before that, often before a single ounce has been pulled from the ground.

The sequence:

1. Exploration and resource definition. Drilling programs establish a defined, measured resource (reported under standards like JORC or NI 43-101).

2. Feasibility study. An independent technical report models the economics: grade, strip ratio, recovery rate, all-in sustaining cost, mine life.

3. Project financing. This is the step that matters most for a trader, because it's where the gold gets committed before it exists. A mine at this stage typically needs hundreds of millions of dollars in construction capital, and mining companies rarely fund that entirely from equity. They raise it by selling forward claims on the gold itself:

   • Streaming agreements. A streaming company pays the miner an upfront lump sum in exchange for the right to buy a fixed percentage of future production at a steep discount to spot, for the life of the mine.

   • Royalty agreements. Similar upfront capital, but the financier takes a percentage of revenue or production rather than a right to buy metal directly.

   • Offtake agreements with banks or refiners. A bank or major refiner (often one already on the LBMA Good Delivery List) agrees to purchase all or a fixed share of doré output for a set term, sometimes attached to a prepayment facility that also functioned as project financing.

4. Construction and commissioning.

5. Production. The mine pours doré bars, typically 60 to 95 percent gold with silver and base-metal impurities, which get shipped to a refinery for final processing into LBMA-standard bars.

What this means for a desk: by the time an industrial mine is actually producing, a meaningful share of its output, sometimes all of it, is already legally committed under a streaming, royalty, or offtake structure signed during construction financing. If someone approaches you offering "direct from mine" gold from a named, operating industrial project, the first question isn't about price or purity. It's this: who holds the existing offtake, and how much of this production, if any, is actually uncommitted? A legitimate seller with genuine free-market volume, whether that's excess production above a streaming cap, a smaller mine that self-financed without giving up offtake rights, or output from a mine whose original financing has already been repaid, can usually answer this without hesitation. Someone who can't or won't explain why gold from a large financed mine is available on the open market is describing a deal that most likely doesn't have the legal right behind it to close.

Artisanal Gold Mining: A Completely Different Supply Chain

Artisanal and small-scale mining (ASM), meaning informal, low-mechanization operations, often alluvial panning or shallow hard-rock digging, runs almost nothing like the industrial process above, and it's where the large majority of gold fraud in this site's Forensic Files coverage has originated.

The sequence:

1. Extraction. Individual miners or small cooperatives work a site, often without the capital-intensive infrastructure of an industrial operation. Output is raw: gold dust, small nuggets, or crude amalgam.

2. Local aggregation. A local buying house, trading post, or "comptoir" purchases small lots from many individual miners, consolidating fragmented production into tradeable volumes. This is the point where provenance starts to blur. Gold from a licensed, legitimate ASM site and gold from an unlicensed or conflict-affected site can enter the same aggregation point with no reliable way to distinguish them by looking at the metal itself.

3. Formalization and licensing. In jurisdictions with functioning regulatory frameworks, aggregated gold is supposed to pass through a licensed dealer who declares it to the state mining authority, pays applicable royalties and export taxes, and obtains an export permit. This step is exactly where the Gambia doré case covered in this site's Forensic Files broke down. A valid dealer license existed, but a valid dealer license says nothing about whether the specific gold behind it is what it's claimed to be.

4. Domestic assay and refining. Before export, material is often taken to a local refinery for a preliminary assay and cast into doré bars. This is the second major failure point: a local facility that won't allow independent testing, as in the Gambia case, has effectively removed the buyer's ability to verify anything before money moves.

5. Export and international sale. The doré reaches an international buyer, trader, or refinery, ideally with a full document chain: mining license, export permit, assay certificate, and (increasingly, under frameworks like the OECD Due Diligence Guidance) a documented chain of custody back toward the mine site.

What this means for a desk: artisanal gold isn't inherently riskier than industrial gold. Plenty of ASM output is fully legitimate and formally documented, but the chain has more handoff points, more informal actors, and more places for a licensing document to substitute for genuine verification. The questions that matter here are different from the industrial case, not "who holds the offtake," but "can every link in this custody chain, miner to aggregator to licensed dealer to exporter, actually be independently confirmed, or does the chain rely on trusting one document that nobody has re-checked against reality?"

What's Actually in Front of the Trader

Strip away the marketing language sellers attach to these offers, and what reaches a desk is almost always one of these:

What's Offered	Industrial or Artisanal	Key Question Before Proceeding
"Mine-direct" doré from a named operating industrial project	Industrial	Is this volume inside or outside an existing offtake or streaming commitment?
Aggregated doré bars from a licensed regional dealer	Artisanal (formalized)	Does the chain of custody trace back to a specific, verifiable mine site or set of sites?
Loose gold dust, bars, or nuggets with a dealer license but no clear mine of origin	Artisanal (informal)	Can origin be established at all, or is this effectively unprovenanced?
Gold already cast and assayed at a named refinery	Either	Was the refinery's assay independently witnessed, or taken on trust?

Safeguarding the Transaction, General Principles

Regardless of which chain the gold came from, the same core protections apply, drawn directly from the failure points this site's fraud autopsies keep exposing.

Verify licensing directly with the issuing authority, not from the document alone. A license or export permit can be genuine and the transaction can still be fraudulent. The paper proves a filing was made, not that this specific gold is legitimately behind it.

Never accept a refinery's assay if the refinery refused independent testing. Any facility that won't allow a buyer's own inspection representative to draw a parallel sample or use independent XRF equipment has told you everything you need to know before you've spent a dollar.

Structure payment against confirmed content, not declared content. This is the core problem in essentially every gold fraud this site has documented. Money moved based on what a seller's paperwork claimed, before anyone independently confirmed what was actually there. Which brings us to the safeguard built specifically to solve this.

Melt-and-Pay: The Safest Structure, Broken Down

Melt-and-pay is widely regarded as the safest settlement structure for a physical gold transaction, because it removes the single biggest point of failure in every case this site has covered: paying based on a declared purity that nobody independently verified before funds moved.

The mechanics:

1. Independent refinery selection. Both parties agree on a refinery that is genuinely independent of the seller, ideally an LBMA Good Delivery-listed refiner or an equivalent accredited facility. This is the step that makes or breaks the entire structure. Melting at a refinery controlled by, or complicit with, the seller is not melt-and-pay. It's the exact black box assay trap from the Gambia case, just with an extra step.

2. Melt and refine. The doré isn't simply melted for a quick sample and left in doré form. The refinery carries the material through its actual refining process, typically electrolytic or chemical, toward standardized fine bullion at 999.9 purity, the same standard LBMA Good Delivery bars are held to. Melting the raw material also solves a fraud problem on its own: uneven purity across a bar, such as a thin layer of real gold plated over base metal, can't survive melting. Once liquid, whatever is actually in the material is uniformly mixed, so there's nowhere left for a fraud to hide before sampling.

3. Dip sampling. During this refining process, a sample is drawn directly from the molten metal. A sampling tool is dipped into the melt, and the metal clinging to it solidifies almost instantly on contact with air, producing a small solid sample, typically a few grams, that's chemically representative of the whole melt at that moment. This is the same method LBMA referees use to test Good Delivery refiners' own output. Sampling from the liquid melt matters because it happens while the metal is genuinely homogeneous; a solid bar can segregate slightly as it cools, so a piece cut from a finished bar isn't guaranteed to represent the whole. Multiple dips are typically drawn from the same melt so that more than one party has material to test, and a dip sample only means anything if the buyer's own representative, or an independent inspector acting for the buyer, actually witnesses it being drawn.

4. Split-sample assay. This is the heart of the safeguard. The refinery runs its own assay on one sample. The buyer (or the buyer's independent inspector) is entitled to have a separate sample tested, either by their own accredited lab or by a mutually agreed independent referee. Industry-standard splitting limits are tight: commonly around 0.05 percent for gold. If both assays fall within that tolerance of each other, the refinery's result stands. If they diverge beyond it, either party can call for an umpire assay, a third, independent lab whose result becomes final, with settlement based on whichever of the two original assays lands closer to the umpire's number.

5. Bullion outturn and payment. Once the refining process is complete and the fine content is certified, payment is calculated on the actual refined fine ounces in the resulting bullion, not the seller's original declared weight or purity, minus any agreed refining or treatment charge and payable percentage. Refiners typically don't pay out 100 percent of assayed content; a small deduction covering refining losses and margin is standard and should be agreed in writing before the melt, not after.

Why this defeats the fraud patterns this site has documented: the West African doré case worked specifically because the buyer relied on a certificate from a refinery that controlled the entire testing process and barred outside verification. Melt-and-pay, done correctly, makes that structurally impossible. The buyer's own representative witnesses the melt and the dip sample, the buyer's own sample goes to an independent assay, and payment only happens once the refined bullion's actual fine content is certified. The fraud doesn't have anywhere to hide, because nobody is paying against a document anymore. They're paying against a jointly verified physical result.

The one place this safeguard still fails is if a buyer treats "melt-and-pay" as a phrase rather than a specific procedure, agreeing to melt at a facility the seller chose and controls, without an independent representative present, without a genuinely independent split-sample assay. At that point it's melt-and-pay in name only, and it protects nobody.
