Gold Mining Supply Looks Set To Decline

The increased spending, however, has not produced the equivalent in new gold discoveries. During the past decade, 41 discoveries have resulted in a mere 215.5 million ounces of the precious metal. Even counting recently discovered but unexplored mines, which may hold as-yet major discoveries, the total available amount of gold in these discoveries are not expected to surpass 363 million ounces over the next ten years.

Gold discoveries have followed a predictable pattern. 263 major gold discoveries have been made in the past 28 years, but half of those discoveries happened in the 1990s. This boom lasted until the turn of the century when the rate of discovery began to decline. Only 16 discoveries were reported from 2000 to 2002, which produced 108.3 ounces of gold. That amount was below the average finds of the 1990s. This decline has continued, with both new discoveries and the amount of gold mined decreasing steadily. By 2010, only 18.6 million ounces of gold was discovered, a severe drop from the 61.5 ounces found in 2009.

Old sectors are being depleted, while active exploration for new discoveries has been slow. The amount of available gold has not met expectation and remains far below the 2009 high.

The lack of new discoveries is not the result of funding. $54.3 billion has been allocated to exploration during the past decade. Part of the problem is that the time span between discovery and production is around 20 years. Unless significant new discoveries are made, the amount of available gold could decrease in the near future, raising the demand for the metal even further. Scarcity invariably results in higher prices, and the decline in global gold makes a price increase almost certain.

Continued gold exploration has become critical. In 2018, Colorado-based Newmont Mining Corp., one of the world largest gold explorers, has allocated $1.3 billion to expand its current projects, an increase of $300 million from the previous year.

Much of the available gold in Australia’s northern Goldfield has been depleted, and companies are drilling to unprecedented depths of 3 kilometers below the surface hoping for new discoveries as new finds are becoming rarer and more expensive to pursue.

According to Richard Schodde, managing director of MinEx, Australia gold mining output could decrease by 50 percent over the next eight years, with only four mines remaining open by 2057.

The need to drill deeper will make gold harder to find and more expensive to produce.
