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.
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.
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.
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.
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.
20 Common Metal Alloys and What They’re Made Of
You can’t find stainless steel, brass, sterling silver, or white gold on the periodic table. Learn about 20 common metal alloys, and what they are made from.
Every day, you’re likely to encounter metals that cannot be found anywhere on the periodic table.
You may play a brass instrument while wearing a white gold necklace – or maybe you cook with a cast iron skillet and store your leftovers in a stainless steel refrigerator.
It’s likely that you know these common metal alloys by name, and you can probably even imagine what they look and feel like. But do you know what base metals these alloys are made of, exactly?
Common Metal Alloys
Today’s infographic comes to us from Alan’s Factory Outlet, and it breaks down metal and non-metal components that go into popular metal alloys.
In total, 20 alloys are highlighted, and they range from household names (i.e. bronze, sterling silver) to lesser-known metals that are crucial for industrial purposes (i.e. solder, gunmetal, magnox).
Humans make metal alloys for various reasons.
Some alloys have long-standing historical significance. For example, electrum is a naturally-occurring alloy of gold and silver (with trace amounts of copper) that was used to make the very first metal coins in ancient history.
However, most of the common metal alloys on the above list are actually human inventions that are used to achieve practical purposes. Some were innovated by brilliant metallurgists, while others were discovered by fluke, but they’ve all had an ongoing impact on our species over time.
Alloys with an Impact
The Bronze Age (3,000 BC – 1,200 BC) is an important historical period that is rightfully named after one game-changing development: the ability to use bronze. This alloy, made from copper and tin, was extremely useful to our ancestors because it is much stronger and harder than its component metals.
Steel is another great example of an alloy that has changed the world. It is one of the most important and widely-used metals today. Without steel, modern civilization (skyscrapers, bridges, etc.) simply wouldn’t be possible.
While nobody knows exactly who invented steel, the alloy has a widely-known cousin that was likely invented in somewhat accidental circumstances.
In 1912, English metallurgist Harry Brearley had been tasked with finding a more erosion-resistant steel for a small arms manufacturer, trying many variations of alloys with none seeming to be suitable. However, in his scrap metal heap – where almost all of the metals he tried were rusting – there was one gun barrel that remained astonishingly untouched.
The metal alloy – now known to the world as stainless steel – was a step forward in creating a corrosion-resistant steel that is now used in many applications ranging from medical uses to heavy industry.
How AI and Big Data Will Unlock the Next Wave of Mineral Discoveries
Mineral exploration produces massive amounts of data. With AI, geologists can produce geological insights from this data to make the next discovery.
How AI and Big Data Will Unlock the Next Mineral Discovery
Emerging technologies such as artificial intelligence (AI) and machine learning are rapidly proving their value across many industries.
Today’s infographic comes from GoldSpot Discoveries, and it shows that when this tech is applied to massive geological data sets, that there is growing potential to unlock the next wave of mineral discoveries.
Mineral Exploration: Fortunes Go to the Few
Discovering new sources of minerals, such as copper, gold, or even cobalt, can be notoriously difficult but also very rewarding. According to Goldspot, the chance of finding a new deposit is around 0.5%, with odds improving to 5% if exploration takes place near a known resource.
On the whole, mineral exploration has not been a winning prospect if you compare the total dollar spend and the actual value of the resulting discoveries.
Measuring Discovery Performance by Region (2005 to 2014)
|Region||Exploration Spend||Estimated Value of Discoveries||Value/Spend ratio|
|Australia||$13 billion||$13 billion||0.97|
|Canada||$25 billion||$19 billion||0.77|
|USA||$10 billion||$5 billion||0.48|
|Latin America||$33 billion||$19 billion||0.57|
|Pacific/SE Asia||$8 billion||$4 billion||0.49|
|Africa||$20 billion||$23 billion||1.19|
|Western Europe||$4 billion||$2 billion||0.42|
|Rest of World||$27 billion||$8 billion||0.32|
|Total||$140 billion||$93 billion||0.57|

Aside from the geographic insights, on the surface this data reveals that mineral exploration does not pay for itself. That said, there are still significant discoveries worth billions of dollars – it’s just the returns go inordinately to a few small players that make big finds.
Much of the money spent on exploration may not have produced the next great discovery, but you can be sure it created massive volumes of data that could be used for further refining of exploration models.
So, What is the Problem?
Every exploration failure or success produces geological insights. The mineral exploration process is the source of massive amounts of data in the form of soil samples, chip samples, geochemistry, drill results, and assay results. Each drill hole is a tiny snapshot into the processes that form the earth.
A single drill hole can create 200 megabytes of data and when there are many drill holes coupled with other types of information, an exploration project can produce terabytes of data. If you wanted to compare your one project to hundreds of others to find the best insights, the amount of data becomes dizzying.
All these data points are clues that can be used to find new mineral deposits, but to sort through them is too much for even an entire team of capable geologists.
Luckily, using today’s technology, this data can now be used to train computers to spot the areas showing similar patterns to past discoveries.
The true power of AI will be in its ability to empower technically trained professionals to make decisions in an increasingly complex and data-driven world.
Professor Ajay Agrawal, a noted academic in AI and founder of the University of Toronto’s Creative Destruction Lab, categorizes human activities into five categories:
- Data collection
- Information retrieval
He concludes that machines should do the first three and that humans – such as geologists, doctors, lawyers, investment bankers and others – should make the judgment calls and take the actions based on predictive capabilities of AI.
The mineral exploration industry presents a good example of how AI and big data can help technical professionals make discoveries faster, with less money, using a wide variety of data inputs created.
Opportunity Generator and the AI-friendly Future
AI can take the large amounts of data from many different projects in order to spot the right opportunities to further explore, building on decades of geological data from projects around the world.
The right technology can help reduce the risk inherent in exploration and lead to more mineral discoveries on budget, rewarding those that deployed their data most effectively. Companies that are able to harness this power will tip the scales in their favor.
As a result, mineral exploration is no longer so much an art of interpretation – but instead, it becomes closer to a pure science, giving geologists a whole-field perspective of all the data.
