Sustained global demand for gold has driven prices to record highs, shifting international focus toward nations holding vast unmined subterranean gold deposits. These underground reserves are positioned to shape the long-term dynamics of the global precious metals market.
Russia and Australia Command Top Spot
Data released by the United States Geological Survey (USGS) in January 2025 places Russia and Australia jointly at the top of world rankings for extractable underground gold. Both nations hold 12,000 tonnes of unmined reserves each, together accounting for roughly 40 percent of the global unmined total.
Based on the benchmark valuation of $4,362 per troy ounce used in the report, the underground gold reserves of Russia and Australia are valued at approximately $1.687 trillion for each country.
Top Five Gold Reserves and Valuation
South Africa ranks third globally, with an estimated 5,000 tonnes of gold remaining underground, valued at around $701 billion. Indonesia takes the fourth spot with 3,800 tonnes of unmined reserves, followed by Canada in fifth place with 3,200 tonnes.
Positions Six Through Ten
Although China and the United States are major current producers, their unmined reserve rankings place them sixth and seventh globally. China holds 3,100 tonnes of unmined gold, while the United States possesses 3,000 tonnes.
Peru occupies the eighth position with 2,500 tonnes, Brazil ranks ninth with 2,400 tonnes, and Kazakhstan round out the top ten with 2,300 tonnes of underground gold deposits.
Combined Wealth Exceeding $7 Trillion and Economic Impact
A key finding from the data is that more than 85 percent of all unmined gold reserves worldwide are concentrated within these top ten countries. Collectively, the underground wealth of these ten nations exceeds $7 trillion at current baseline pricing.
This concentration opens significant investment opportunities in emerging economies such as Indonesia, Peru, and Brazil. Major mining corporations seeking efficient supply chains and lower extraction costs are increasingly eyeing these markets, which could provide substantial economic growth for host nations.
Surge in African Exploration
Beyond South Africa's major reserve position, exploration activity across the African continent is accelerating rapidly. Ghana holds 1,000 tonnes of unmined gold, Mali possesses 800 tonnes, and Tanzania accounts for 400 tonnes, making these nations crucial centers for ongoing gold discovery and development.
