Gold's allure is timeless, but beyond the bars stacked in vaults, vast treasures remain locked deep within the Earth. Understanding where the largest untapped reserves lie is key to the future of global supply. Recent U.S. Geological Survey (USGS) assessments pinpoint two nations above all others: Australia and Russia are estimated to hold geological fortunes of around 12,000 metric tons of gold each, still waiting underground.
Russia’s Largest Gold Deposits
Based on recent estimates from TAdviser (citing Russia’s state balance sheet as of March 2025), some of Russia’s largest gold reserves include:
- Sukhoy Log (Irkutsk): Over 2,770 tonnes, making it Russia’s largest gold deposit.
- Natalkinskoye (Natalka) (Magadan): Around 1,385 tonnes.
- Olympiadinskoye (Olimpiada) (Krasnoyarsk): Approximately 949 tonnes.
These three deposits account for a significant share of Russia’s total gold reserves, positioning the country as one of the world’s top gold-rich nations. However, reserve estimates can vary depending on the source and methodology.
Australia’s Largest Gold Deposits
Similarly, Australia boasts some of the largest gold deposits globally. Based on recent reports, key reserves include:
- Cadia Valley (New South Wales): Operated by Newmont, with estimated reserves of approximately 17 million ounces (as of June 2023).
- KCGM / Super Pit (Western Australia): Operated by Northern Star Resources, holding reserves of 13.3 million ounces (as of mid-2023/2024).
- Boddington (Western Australia): Operated by Newmont, with reserves estimated at 10.8 million ounces (as of December 31, 2024).
Other Countries with Major Gold Reserves
While Russia and Australia lead in total reserves, other countries also hold significant in-ground gold:
- South Africa – 5,000 metric tons
- Indonesia – 3,600 metric tons
- China – 3,100 metric tons
- United States – 3,000 metric tons
- Canada – 3,200 metric tons
- Brazil – 2,400 metric tons
- Peru – 2,500 metric tons
- Kazakhstan – 2,300 metric tons
These reserves represent gold yet to be mined but confirmed through geological surveys and exploration efforts.

When LONGi Green Energy, the world's largest solar module maker, told investors on January 5, 2026 that it would begin mass-producing base-metal solar cells in the second quarter, it put a number on a pressure the whole industry feels. Solar is the largest single application within silver's industrial demand, and as the metal ran to a record above $121 an ounce in January, rising silver costs pushed manufacturers to accelerate efforts to reduce the metal per cell.

In early 2026, the artificial intelligence narrative shifted abruptly from software capabilities to physical hardware constraints. With tech giants committing hundreds of billions to new infrastructure—pushing global hyperscaler capital expenditures past $600 billion this year—the industry has collided with a new primary bottleneck: a severe power and thermal crunch.

Somewhere inside a pressurized-water reactor, an alloy that is four-fifths silver is absorbing neutrons to keep the core in check, a job most silver investors have never heard of. It is a useful reminder that the metal people picture as coins and jewelry mostly works elsewhere, across industry.

Mexico remained the world's top silver-producing country in 2025, mining 172.9 million ounces (Moz), roughly a fifth of global supply, according to the World Silver Survey 2026, produced for the Silver Institute by Metals Focus. But Mexico's lead narrowed: its output fell 5% for a third straight year, while second-place Peru climbed 7%. Global mine production rose 3% to 846.6 Moz, even as the ranking's top tier told a story of one leader sliding and its closest rival closing in.
