Sustainable
Gold Mining

A quarter of the world’s gold is mined by hand, off the record, with mercury. We turned that into an ecosystem you can trust, verify, and enter.

01 / The reality

The most consequential gold on earth is the gold no one can trace.

18.2M
people work in artisanal & small-scale gold mining (ASGM)
~20%
of the world’s gold supply, mostly informal
~37%
of global mercury pollution. ASGM is the single largest source
1.76 kg
of mercury released for every kilogram of gold
350,000 ha
of Amazon forest & wetland lost to placer mining
$3M
to fully remediate a single contaminated hectare

Source: Conservation X Labs, Gold Reimagined (2025). With gold near $3,000/oz, the pressure and the damage are accelerating.

Every gram of gold starts in <em>a real place</em>.

02 / The ecosystem

Follow the gold. Watch where trust breaks.

Sustainable gold is a chain, and every link has a failure mode the next one launders away.

01 / Miners
Extraction
Informal, low-tech, remote. No proof, no premium for doing it right.
02 / Processing
Mercury
Amalgamation recovers up to 90%, and poisons people, water and forest.
03 / Aggregators
The middlemen
“Logistical entrepreneurs” sell paper traceability without changing the ground.
04 / Refiners
The blend
Gold melts. Legal and illegal origin become one bar, untraceable.
05 / Buyers
Brands
Low willingness to pay. No demand signal rewards clean gold.
Gold is easy to blend legal and illegal into one bar. Traceability remains a neglected gap.

03 / The dependency stack

Nothing higher works until the layer beneath it does.

The sector’s own research maps a strict order. Transparent markets need formalization; formalization needs verification. The base and the apex remain unsolved.

Unsolved · Saphi
Transparent markets & payment
Traceability is “still in pilot mode,” buyers will not pay a premium, and there is no secured rail to reward verified miners.
Partly solved
Formalization & best practice
Standards exist (Fairmined, CRAFT). They stall without proof beneath them and demand above.
Unsolved · Antiari
Monitoring & verification
Monitoring exists, yet there is “no significant evidence” of real mercury or deforestation reduction. Proof is not yet tied to consequence.

Read it bottom-up: verification carries the whole stack. That base is Antiari. That apex is Saphi.

04 / The verification protocol
Antiari. Proof that changes behavior.

The sovereign AI of the nature economy, applied to gold. It produces evidence: satellite to soil, gram to ledger, admissible enough to act on.

Satellite & SAR monitoring
Mining detected through cloud and canopy, month over month, at the accuracy the field has proven (~94%).
Parcel & plant-level ground truth
Geo-anchored evidence at the mine and the concession: mercury-free, deforestation-free, where it happened.
Provenance & chain of custody
Origin bound to the gram before it can be blended away. The failure mode of every paper scheme, closed.
Court-admissible by design
Verification built to stand up in enforcement and offtake. Proof you can act on.
05 / Ecosystem acceleration
Saphi. From a verified gram to a real market.

Proof opens the door. Saphi builds the four mechanisms that turn verified gold into demand, payment, and trust.

Mechanism 01
Offtake & demand
We aggregate the premium buyers and brands, creating the demand signal for verified gold that the market never had.
Mechanism 02
Secured fragmented payments
Split, escrowed payment released on proof-of-provenance: the rail that pays verified miners a premium at the gram.
Mechanism 03
Trust & formalization
Informal miners become legal, bankable, certified suppliers, the on-ramp from the shadow economy to the real one.
Mechanism 04
MRV-gated value routing
Value flows only on verified outcomes: mercury-free, deforestation-free. Antiari measures; Saphi moves the money.

Payment moves when the forest is <em>still standing</em>.

06 / The gateway

The key to enter the ecosystem.

Every actor has been waiting on the same two things: proof, and a market that rewards it. Saphi holds that door open.

Miners & cooperatives
Get certified, financed, and paid a premium for gold you can prove.
Buyers & brands
Source gold with provenance you can audit and a conscience you can defend.
Governments
Formalize the informal and enforce with evidence that holds up.
Financiers
Underwrite verified flows: blended finance and advance commitments, de-risked by proof.
