Gold Dore Bars: Complete Guide for Buyers (2026)

# Gold Dore Bars: Complete Guide for Buyers (2026)

Gold dore bars represent one of the most significant opportunities in the global precious metals supply chain. For institutional buyers, understanding what gold dore bars are, how they are produced, how pricing works, and what compliance requirements apply is essential for successful procurement. This 2026 guide provides a comprehensive overview of gold dore bars — from production and refining through to purchase and export.

What Are Gold Dore Bars?

A gold dore bar (sometimes spelled doré) is a semi-pure alloy of gold and silver, produced at mining operations before final refining. The term "dore" comes from the French word meaning "gilded" or "golden." These bars are the standard intermediate product in the gold supply chain, representing the transition point between raw mine output and investment-grade refined gold.

Dore Bar Composition

Gold dore bars typically contain between 60% and 95% gold, with the remainder consisting primarily of silver, along with trace amounts of copper, palladium, and other minerals. The exact composition varies significantly depending on the ore source and mining region.

Typical Dore Bar Composition by Region:

• ◈**East Africa (Uganda, Tanzania, Kenya)**: 75-92% gold, 5-20% silver, 1-5% other metals
• ◈**West Africa (Ghana, Burkina Faso, Mali)**: 80-95% gold, 2-15% silver, 1-3% other metals
• ◈**South America (Peru, Colombia)**: 65-85% gold, 10-30% silver, 2-5% other metals
• ◈**Central Asia (Uzbekistan, Kazakhstan)**: 70-90% gold, 5-25% silver, 2-5% other metals

How Gold Dore Bars Are Produced

The production of gold dore bars follows a multi-stage process that begins with ore extraction and ends with a cast bar ready for refining:

Stage 1: Ore Extraction Gold-bearing ore is extracted from open-pit or underground mines. In East Africa, artisanal and small-scale miners (ASM) also produce significant quantities using hand-dug shafts and alluvial panning methods.

Stage 2: Crushing and Grinding The extracted ore is crushed and ground into fine particles, typically to 75 microns or less, to liberate gold particles from the host rock.

Stage 3: Concentration Gold is concentrated through gravity separation, flotation, or cyanide leaching. In East Africa, gravity concentration is the predominant method for artisanal operations, while industrial mines use cyanide leaching (CIL/CIP processes).

Stage 4: Smelting The concentrated gold is smelted at temperatures exceeding 1,064°C (gold's melting point) with flux materials that remove impurities. This produces a molten mixture of gold and silver.

Stage 5: Casting The molten alloy is poured into molds and allowed to cool, forming the characteristic dore bar shape. Bars are then stamped with identifying marks including weight, purity estimate, and producer identification.

Dore Bar vs. Refined Gold: Key Differences

Understanding the distinction between gold dore bars and refined gold bullion is fundamental for buyers:

• ◈**Purity**: Dore bars (60-95% gold) vs. refined bars (99.5-99.99% gold)
• ◈**Form**: Dore bars are rough, unrefined castings vs. refined bars are minted or cast to precise specifications
• ◈**Pricing**: Dore bars are priced at a discount to spot (reflecting refining costs and impurity risk) vs. refined bars trade at or near spot price
• ◈**Market**: Dore bars trade between miners and refineries vs. refined bars trade in investment and jewelry markets
• ◈**Regulation**: Dore bars require ICGLR certification for export from East Africa vs. refined bars are LBMA-standard products

Gold Dore Bar Pricing Explained

Pricing gold dore bars accurately requires understanding the several components that determine value. Unlike refined gold, which trades at or near the London Fix, dore bars involve additional calculations.

How Gold Dore Bar Prices Are Calculated

The price of a gold dore bar is determined by:

1. Fine Gold Content

Fine gold content = Gross weight × Assayed purity (%)

For example, a 10kg dore bar assayed at 85% purity contains 8.5kg of fine gold.

2. Spot Price Adjustment

The fine gold content is multiplied by the prevailing London Fix spot price. However, sellers typically receive a percentage below spot to account for refining costs and market risk.

3. Silver Credit

Silver content in dore bars has commercial value. The silver credit is calculated as: - Silver weight = Gross weight × Assayed silver purity - Silver value = Silver weight × Spot silver price × Recovery factor (typically 80-95%)

4. Refining Charge

Refineries charge for converting dore bars into LBMA-grade gold. Typical refining charges are: - Fixed fee: $3-8 per ounce of fine gold - Or percentage: 0.15-0.50% of fine gold value - Minimum charges may apply (typically 500 oz minimum)

5. Penalty Elements

Certain impurities attract penalty charges: - Copper: $0.50-2.00 per ounce above threshold - Arsenic: $1.00-5.00 per ounce above threshold - Antimony, Bismuth, Tellurium: Variable penalties based on concentration

6. Transport and Insurance

• ◈Secure transport to refinery: $0.50-2.00 per ounce
• ◈Insurance: 0.15-0.25% of shipment value

Full Pricing Example

Consider a 10kg gold dore bar with the following assay: - Gross weight: 10,000 grams (321.51 troy ounces) - Gold purity: 87.5% - Silver purity: 10.0% - Other: 2.5%

Valuation: - Fine gold: 8,750g (281.32 oz) × $2,380/oz = $669,543 - Silver credit: 1,000g (32.15 oz) × $28/oz × 85% recovery = $765 - Less refining: 281.32 oz × $6/oz = ($1,688) - Less penalties (estimated): ($500) - Less transport/insurance: ($1,000) - Net value: approximately $667,120

This represents approximately 99.6% of the fine gold spot value, with the ~0.4% discount covering refining, transport, and handling costs.

Pricing Transparency Best Practices

When sourcing [gold dore bars from Uganda](/gold/dore/uganda/kampala), buyers should insist on:

Frequently Asked Questions

What is a gold dore bar?

A gold dore bar (or doré bar) is a semi-pure alloy of gold and silver produced at mining operations before final refining. Gold dore bars typically contain 60-95% gold, with the remainder being silver and trace metals. They are the standard intermediate product in the gold supply chain, sold by miners to refineries for further purification into investment-grade bullion (99.5%+ gold purity).

How much does a gold dore bar cost?

The price of a gold dore bar depends on its fine gold content, prevailing spot gold prices, and applicable discounts for refining. As of 2026, a gold dore bar with 85% gold purity would be priced at approximately 98-99% of the spot gold price per ounce of fine gold content. For example, with gold at $2,380/oz, an 85% pure dore bar containing 281 ounces of fine gold would have a net value of approximately $667,000, after accounting for refining charges, silver credits, and handling costs.

How is gold dore bar purity tested?

Gold dore bar purity is tested through three primary methods: (1) XRF (X-ray Fluorescence) screening for rapid on-site estimation, (2) Fire assay for definitive gold determination — the industry standard with accuracy to 0.01%, and (3) Gravimetric analysis for silver content. Best practice requires independent assay by accredited laboratories such as SGS or Intertek, with split samples retained by both buyer and seller for dispute resolution.

What is ICGLR certification for gold?

ICGLR certification is a regional certification mechanism administered by the International Conference on the Great Lakes Region to verify that gold originates from conflict-free sources. It is mandatory for all gold exports from Uganda and other ICGLR member states. The certification requires documented chain of custody from mine to export, third-party supply chain audits, and per-shipment certificates with unique tracking numbers. ICGLR certification is recognized by the OECD, EU, and major LBMA-accredited refiners as evidence of responsible sourcing.

Can individuals buy gold dore bars?

Gold dore bars are primarily traded between mining companies, licensed exporters, and refineries. While individuals can technically purchase dore bars, the practical barriers are significant: most reputable suppliers deal only with institutional buyers, refining access requires commercial relationships with registered refineries, and the minimum order quantities are typically 5-10 kg. For most individual investors, [purchasing refined gold bars](/gold-bars) is more practical and accessible.

How do I verify a gold dore bar supplier?

To verify a gold dore bar supplier: (1) Request and verify their Mineral Exporter's License directly with the DGSM in Uganda, (2) Confirm ICGLR certification status through the ICGLR portal, (3) Check business registration with URSB (Uganda Registration Services Bureau), (4) Request and verify at least three trade references, (5) Conduct PEP (Politically Exposed Person) screening on directors and beneficial owners, (6) Perform negative news search, (7) Visit the supplier's premises or request video verification, (8) Start with a small trial order before committing to larger volumes.

What are the tax implications of buying gold dore bars?

In Uganda, gold dore bar exports are subject to a 3% export duty calculated on the FOB value of the shipment. Additional costs include ICGLR certification fees (0.5% of FOB value, minimum $500), DGSM export permit fees (approximately $135 per shipment), and customs processing fees. Corporate income tax of 30% applies to the exporter's profits. For buyers importing into their own jurisdiction, VAT and import duties may apply depending on local regulations. Total transactional costs typically range from 3.5-5% of FOB value.
