List your asset
Mine claim, mineral rights, or industrial feedstock. Free to list. The platform pulls public record data, generates a MotherLode Score, and produces a value estimate before the listing goes live.
Marketplace
The first marketplace where every listing is scored before it goes live.
Mine claims. Mineral rights. Industrial feedstock. Every listing carries a MotherLode Score — calculated from the same integrated dataset that powers the full platform. No guessing. No misrepresentation. No blind offers.

How it works.
Every other mining marketplace is a listing board — asking price, a seller description, and no way to know if the site is worth what someone is asking. MotherLode Marketplace changes every part of that.

Buyers find you by score
Buyers search and filter by MotherLode Score, commodity, state, price, and rework cost. Your asking price is benchmarked against the score — fairly priced listings surface first. Deal alerts notify matched buyers instantly.

Close with confidence
Verified assays, chain-of-custody documentation, comparable closed transactions, scam pattern screening, and a per-state tax calculator. Four percent commission at close — the marketplace earns when you earn.
Three asset classes. One scoring engine.
Whether you are selling a forty-acre gold claim, leasing mineral rights on inherited land, or moving five hundred tons of REE-bearing tailings to a refiner — every listing carries a MotherLode Score calculated from the same integrated dataset.
Mine Claims
Active claims, patented ground, and open BLM parcels. Each listing shows the MotherLode Score, bycatch predictions with confidence intervals, claim status, regulatory pathway, and estimated rework economics. Asking price benchmarked against the score on every listing.
Mineral Rights
Sell outright or lease with a defined royalty structure. The scoring engine evaluates mineral rights parcels the same way it evaluates mine claims — bycatch potential, commodity mix, era-specific recovery models, and current market value. Both sale and lease listings supported.
Industrial Feedstock
Tailings operators and site owners list available material by tonnage, mineral composition, purity grade, and delivery logistics. Refiners and processors search by the mineral they need, the volume they need, and the region they need it from. The marketplace connects supply to demand.
What makes this different from every other listing board.
Every other mining claim and mineral rights marketplace is a listing board. Asking price, a description the seller wrote, no verification, no valuation, no way to know if the site is worth what someone is asking. MotherLode Marketplace changes every part of that.
Every listing carries a MotherLode Score
No listing goes live without a score. Bycatch potential, historical production, claim status, regulatory complexity, and modern recovery economics — calculated before a buyer asks a single question.
Every asking price benchmarked against the score
A Score-85 site listed at eight thousand dollars is flagged as below market. A Score-42 site listed at forty-five thousand is flagged accordingly. Buyers see the value gap clearly. Sellers who price to the score transact faster.
Verified assays with chain-of-custody documentation
Verified listings require original assay records and chain-of-custody documentation. The platform cross-references submitted documents against historical USGS records for the same site. Discrepancies are flagged before the listing goes live.
Scam patterns flagged automatically
The refile-and-resell pattern, claims sold with misrepresented commodity history, and listings that duplicate previously recorded sites under new names. Flagged listings are held for review before buyer contact is permitted.
Comparable closed transactions — not asking prices
Transaction history based on actual closes, not what people hoped to get. The first marketplace where you can see what similar sites actually sold for.
Every closed transaction feeds the model
Verified outcomes — what the site yielded, what the rework cost, what the actual recovery rate was — flow back into the scoring engine. The marketplace makes the intelligence more accurate with every deal.
Industrial
Built for volume. Built for compliance. Built for the supply chain.
The consumer marketplace connects individual buyers and sellers. The industrial layer connects operators, refiners, processors, and federal program participants at the scale the domestic supply chain requires.
Offtake Agreements
Long-term supply contracts, not one-time sales. Refiners post what they need — mineral type, volume, purity, region. Operators with matching scored sites are surfaced automatically. The marketplace brokers the introduction and documents the agreement.
Request for Quotation Board
Buyers post demand signals: mineral, tonnage, grade, delivery window, target region. Operators with matching supply are notified. The RFQ board creates a live demand signal that tells the market exactly what minerals are needed right now.
Verified Industrial Buyers
Refiners, processors, and DOE or DOD awardees with verified credentials see enriched data — full bycatch breakdowns, recovery economics, and compliance-ready documentation. Verified buyer badge builds trust with serious sellers.
Federal Compliance Package
Per-site documentation formatted for DOE and DOD grant applications, DPA Title III submissions, and program-manager review. Provenance chain, assay history, chain-of-custody, and regulatory pathway — exportable in one click.
Logistics
Total landed cost, not just material cost.
Every industrial feedstock listing includes estimated shipping cost based on tonnage, origin, and destination. Hazmat classification flags for mercury-contaminated tailings. Nearest processing facility mapped.
Industrial buyers evaluate total landed cost before making contact. Sellers who provide logistics detail transact faster and at higher prices.
Price Index
The reference price for domestic secondary feedstock.
Transaction prices tracked over time by mineral, region, and grade. The MotherLode Index becomes the pricing reference for domestic mine tailings and secondary mineral feedstock — a dataset that does not exist today.
As transaction volume grows, the index becomes a licensable data product and a standard reference for the industry.
Know what your site is worth before you list it.
Every seller runs the value estimator before the listing goes live. Low, mid, and high scenario at current commodity prices. No account required.
Scored value range
Based on the site's public record, commodity mix, acreage, and current market prices. Three scenarios: conservative, mid-range, and optimistic.
Per-state tax calculator
Federal capital gains, state severance tax, state income tax, depletion allowance, and the four percent marketplace commission. Net proceeds estimate before you set your asking price.
Deal alert engine
Set your criteria and receive alerts when a matching listing goes live. Score range, commodity type, state, price ceiling. The search does what manual research cannot.
Two listing types. Both free to list.
No listing fees. No monthly charges. Four percent commission at close only. Sellers keep the upside. The marketplace earns when you earn.

Deal Structuring
Mining deals are never just buyer and seller.
A productive transaction often requires a claim owner, an operator, a refiner, and a logistics partner. The marketplace supports multi-party deal structuring around scored sites — bringing all parties into a single coordinated view with shared documentation and transparent economics.
Four percent commission on the completed deal. The marketplace earns when value is created, not before.
