The Future of Gold Exploration is Under Cover

Date: Thursday, June 14, 2018 2:06 PM EST

Over billions of years, extraordinary amounts of gold and other metals were deposited and spread throughout the Earth’s crust. Humans have been searching for these rich deposits for centuries, and advances in geoscience and technology have helped us become more adept at finding them over time.

The Future of Gold Exploration is Under Cover

However, even with today’s advancements – almost all early-stage prospecting methods are still based on the same key principle: trying to find areas of exposed bedrock, called outcrops, that indicate an orebody is near.

But such outcrops only form in certain circumstances – and what happens when a geological system doesn’t come in contact directly with the surface?

THE PROBLEM OF COVER

Today’s infographic comes to us from Nevada Exploration, and it identifies the problem behind finding these “hidden” deposits that do not leave a helpful trail of clues on the surface.

Instead of having outcrops where rocks can be readily sampled, these deposits are trapped underneath large amounts of soil and gravel. Geologists call this a covered setting, where they must first find a way to “see through” the cover in order to identify what geological systems really exist below.

Seeing through cover can be expensive and difficult to do, but it also has big potential upside.

There is no reason not to assume as much gold still exists as has been mined in the past, but prospectors, explorationists, and geologists have found the easy gold.

In fact, many geologists think that the next game-changing gold deposit could be found under cover.

EXPLORATION 2.0

For explorers, it is no secret that the cost per discovery is going up dramatically over time. The reality is that traditional exploration methods are achieving diminishing returns, and as a result companies are settling for lower grade deposits, more complex geological settings, and politically questionable jurisdictions.
