Gold Deposits, Mines and Geology

Gold sits at the centre of this collection, from the countries holding the largest reserves to the mines, maps and deposits that make them. Alongside the geology you will find pieces on Reko Diq, Canada, Afghanistan, Arizona, Alaska and NSW, plus the TV-famous ground of Parker’s Trail and White Water.

Most readers come here for one of three reasons. Prospectors and licence holders want to know how to survey ground, start a small operation or choose an extraction method. Investors want to compare royalty companies, penny stocks and producers, and to understand cost measures such as AISC. Others want the wider picture: health and environmental effects, recovery from electronics and how technology is changing the work.

Checking a specific piece of ground?

Farmonaut Mining Pro reads satellite optical, radar and thermal data to show where a licence area looks most promising, so field work and drilling go to the best targets first.

How much gold is mined each year

World gold mine production was about 3,300 tonnes in 2025, according to the US Geological Survey, almost unchanged from 2024. China, Russia, Australia, Canada and the United States were the five largest producers, in that order, and together they mined about 41% of the total (USGS Mineral Commodity Summaries 2026). The rest comes from dozens of countries, with Ghana, Kazakhstan, Mexico, Uzbekistan and Peru among the larger ones. Our tables of the top 20 gold producing countries and gold reserves by country rank them in full.

As for all the gold mined in the world, the World Gold Council estimates about 222,600 tonnes had been mined in total by the middle of 2026, roughly two-thirds of it since 1950 (World Gold Council). Almost all of it still exists, mostly as jewelry, bars, coins and central bank reserves. Known reserves still in the ground are much smaller, in the range of 60,000 to 66,000 tonnes depending on whose estimate you use.

The geology of gold deposits

Gold deposits form in several quite different ways, and the type decides how a deposit is explored, mined and processed. The main ones:

Deposit typeHow it formsWell-known examples
OrogenicGold-bearing quartz veins in deformed, metamorphosed rock, often in greenstone beltsWestern Australia’s goldfields, the Abitibi belt in Canada, West Africa’s Birimian belts
Porphyry copper-goldLarge, low-grade bodies around intrusions in volcanic arcsGrasberg in Indonesia, many Andean deposits
EpithermalShallow hot-spring systems above intrusionsDeposits around the Pacific Ring of Fire
Carlin-typeMicroscopic gold in sedimentary rockNevada’s Carlin Trend
PaleoplacerAncient gold-bearing river gravels turned to rockSouth Africa’s Witwatersrand Basin
PlacerGold concentrated by modern rivers and streamsAlaska, the Yukon, West African rivers

Orogenic deposits supply a large share of world output, and they are also the type small-scale and artisanal miners most often work, because weathering frees the gold near surface. Our guide to geological surveys for gold resources explains how each type is looked for.

Major gold mining regions and jurisdictions

The largest gold deposits in the world cluster in a few regions. The Witwatersrand Basin in South Africa has produced more gold than any other field in history. Nevada’s Carlin Trend, Muruntau in Uzbekistan, Grasberg in Indonesia and the goldfields of Western Australia are all among the giants. West Africa’s Birimian belts, running through Ghana, Mali, Burkina Faso and neighbors, have been one of the busiest areas for new discoveries in recent decades.

Geology is only half of what makes a good place to explore. The other half is the rules: secure title, a predictable permitting process, fair taxes and royalties, and the ability to export. The Fraser Institute’s annual survey of mining executives is the best-known ranking of mining jurisdictions, and Nevada, Western Australia and several Canadian provinces regularly place near the top. Our map of gold mines in the world shows where production sits today.

How gold royalty companies work

A royalty or streaming company gives a mine developer money up front, usually to help build the mine, in return for a share of future production. A royalty is typically a percentage of revenue, often a net smelter return. A stream is a right to buy a share of the metal at a fixed, low price. The royalty company doesn’t run mines or pay most operating costs, so its results depend on the operators doing well and on the gold price.

The largest names on most gold royalty companies lists are Franco-Nevada, Wheaton Precious Metals and Royal Gold, with Osisko Gold Royalties and a number of smaller firms behind them. This is general information, not investment advice: royalty portfolios can be concentrated on a few mines, and a mine that closes early or a country that changes its rules affects them directly. Our articles comparing Franco-Nevada, Wheaton and Royal Gold and on how royalty firms earn cover them in more detail.

Gold exploration projects and assets

A gold exploration asset is usually a license plus whatever is known about it: maps, sampling, geophysics, drill results. Projects move through recognizable stages, from target generation to first drilling, then to a mineral resource reported under a code such as JORC or NI 43-101, and finally to feasibility studies. Each stage adds value only if it adds evidence.

We work at the very start of that chain. Our satellite mineral detection service ranks Exploration Targets across a license from optical, radar, thermal, terrain and magnetic data, ahead of a JORC or NI 43-101 resource estimate and never in place of one. Ghana is our largest country by area analyzed, and we have published 18 gold case studies, including a non-alluvial gold project in Kenya where 12 g/t was later confirmed. Where clients tested our ranked zones with ground or drill evidence, 90% were confirmed.

Questions about gold deposits and mining

How much gold is mined each year?

About 3,300 tonnes in 2025, according to the US Geological Survey. China was the largest producer, followed by Russia, Australia, Canada and the United States.

How much gold has been mined in history?

The World Gold Council estimates about 222,600 tonnes as of mid-2026, roughly two-thirds of it mined since 1950. Nearly all of it is still above ground as jewelry, bars, coins and central bank holdings.

What are the main types of gold deposits?

Orogenic veins, porphyry copper-gold, epithermal, Carlin-type, paleoplacer (like the Witwatersrand) and placer deposits. They form in different settings, so each is explored and mined differently.

What is a gold royalty company?

A company that pays a mine developer up front in exchange for a percentage of future revenue or the right to buy metal at a fixed price. Franco-Nevada, Wheaton Precious Metals and Royal Gold are the largest. This page explains how they work and does not recommend any stock.
