The Mineral Exploration Roadmap

Mineral Exploration Roadmap

There is nothing more exciting than making some type of discovery.

Discoveries can come in many forms – they can be physical, scientific, personal, or even philosophical in nature. But while there are different types of discoveries that can be made, perhaps the most tactile kind of discovery is in the field of mineral exploration.

The discovery of a mineral deposit can transform a piece of “moose pasture” into a new economic asset, and it may enable millions or billions of dollars worth of metals and minerals to be used for human purposes.

These minerals get used all around us – they go into our houses, cars, infrastructure, jewelry, electronics, and they can even be used to power the green revolution.

From Prospecting to Production

Making an economic mineral discovery is the goal of many teams around the world, but these efforts can also be extremely difficult, costly, and time-consuming, and most companies engaged in exploration end up walking away empty-handed.

Today’s infographic comes to us from Orix Geoscience and it shows the steps of mineral exploration, and how teams can maximize their odds of success by using data to add value throughout the process.

Steps of the Mineral Exploration Process

1. Exploration Strategy

Where do you choose to explore? There are two basic strategies:

(a) Working from the known
Deposits tend to form in clusters in prolific belts, and exploration occurs outward from known mineralization.

(b) Working from the unknown
If you review all available information, prospective areas with potential for discoveries can be identified.

2. Prospecting

In this stage, boots are now on the ground – and it’s time to explore the backwoods for showings. Prospectors will stake claims, map outcrops and showings, and search for indicator minerals.

The goal of the prospecting stage is to find the earliest piece of the exploration puzzle: the clue that there is something much bigger beneath.

3. Early-Stage Exploration

Congrats, you’ve found something interesting – and now it’s time to ramp up exploration efforts!

This is where the amount of data and sophistication picks up. In this stage, companies are using existing maps and historical data, geophysics, ground truthing, geochemistry, and trenching to try and identify drill targets.

4. The “Truth Machine”

Geologists don’t call the drill a “truth machine” for nothing.

If you’re target hits, you’re in business. If your target misses, it’s time to go back a step and find new ones.

5. Discovery

Eureka! You’ve found something. Now it’s time to see how far the mineralization goes!

Once you have enough information, you can get an official resource estimate. This data is another puzzle piece that will be crucial as you advance your discovery.

6. De-risking

Even at the best of times, mining can be expensive, risky, and tricky.

That’s why your investors and backers will want you to source even more data – it’ll allow you to see a clearer picture of the deposit, and help your team see how it could take shape as a mine.

At this stage, drilling, metallurgical tests, environmental assessments, 3d models, and mine designs are used to increase confidence in the project.

Data starts to get very granular. Your company may do a Preliminary Economic Assessment (PEA) to assess the potential economic outcomes of a mine. Then after, they may conduct an in-depth Feasibility Study to help make a production decision.

Final Steps

By this point, you may have all the puzzle pieces – a clear vision of the deposit and its potential – to make a decision!

If the puzzle looks good, it’s time to make a production decision, construct the mine, and start commercial production. But the data doesn’t stop there – at these later stages, even more data gets created and it can help you make better decisions.

Charted: The Value Gap Between the Gold Price and Gold Miners

While gold prices hit all-time highs, gold mining stocks have lagged far behind.

Although the price of gold has reached new record highs in 2024, gold miners are still far from their 2011 peaks.

In this graphic, we illustrate the evolution of gold prices since 2000 compared to the NYSE Arca Gold BUGS Index (HUI), which consists of the largest and most widely held public gold production companies. The data was compiled by Incrementum AG.

Mining Stocks Lag Far Behind

In April 2024, gold reached a new record high as Federal Reserve Chair Jerome Powell signaled policymakers may delay interest rate cuts until clearer signs of declining inflation materialize.

Additionally, with elections occurring in more than 60 countries in 2024 and ongoing conflicts in Ukraine and Gaza, central banks are continuing to buy gold to strengthen their reserves, creating momentum for the metal.

Traditionally known as a hedge against inflation and a safe haven during times of political and economic uncertainty, gold has climbed over 11% so far this year.

According to Business Insider, gold miners experienced their best performance in a year in March 2024. During that month, the gold mining sector outperformed all other U.S. industries, surpassing even the performance of semiconductor stocks.

Still, physical gold has outperformed shares of gold-mining companies over the past three years by one of the largest margins in decades.

200 Years of Global Gold Production, by Country

Global gold production has grown exponentially since the 1800s, with 86% of all above-ground gold mined in the last 200 years.

Visualizing Global Gold Production Over 200 Years

Although the practice of gold mining has been around for thousands of years, it’s estimated that roughly 86% of all above-ground gold was extracted in the last 200 years.

With modern mining techniques making large-scale production possible, global gold production has grown exponentially since the 1800s.

The above infographic uses data from Our World in Data to visualize global gold production by country from 1820 to 2022, showing how gold mining has evolved to become increasingly global over time.

A Brief History of Gold Mining

The best-known gold rush in modern history occurred in California in 1848, when James Marshall discovered gold in Sacramento Valley. As word spread, thousands of migrants flocked to California in search of gold, and by 1855, miners had extracted around $2 billion worth of gold.

The United States, Australia, and Russia were (interchangeably) the three largest gold producers until the 1890s. Then, South Africa took the helm thanks to the massive discovery in the Witwatersrand Basin, now regarded today as one of the world’s greatest ever goldfields.

South Africa’s annual gold production peaked in 1970 at 1,002 tonnes—by far the largest amount of gold produced by any country in a year.

With the price of gold rising since the 1980s, global gold production has become increasingly widespread. By 2007, China was the world’s largest gold-producing nation, and today a significant quantity of gold is being mined in over 40 countries.

The Top Gold-Producing Countries in 2022

Around 31% of the world’s gold production in 2022 came from three countries—China, Russia, and Australia, with each producing over 300 tonnes of the precious metal.

#11🇬🇭 Ghana903%
#12🇮🇩 Indonesia702%
-🌍 Rest of the World1,03033%
-World Total3,100100%

North American countries Canada, the U.S., and Mexico round out the top six gold producers, collectively making up 16% of the global total. The state of Nevada alone accounted for 72% of U.S. production, hosting the world’s largest gold mining complex (including six mines) owned by Nevada Gold Mines.

Meanwhile, South Africa produced 110 tonnes of gold in 2022, down by 74% relative to its output of 430 tonnes in 2000. This long-term decline is the result of mine closures, maturing assets, and industrial conflict, according to the World Gold Council.

Interestingly, two smaller gold producers on the list, Uzbekistan and Indonesia, host the second and third-largest gold mining operations in the world, respectively.

The Outlook for Global Gold Production

As of April 25, gold prices were hovering around the $2,000 per ounce mark and nearing all-time highs. For mining companies, higher gold prices can mean more profits per ounce if costs remain unaffected.

According to the World Gold Council, mined gold production is expected to increase in 2023 and could surpass the record set in 2018 (3,300 tonnes), led by the expansion of existing projects in North America. The chances of record mine output could be higher if gold prices continue to increase.
