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.

Mining has traditionally been depicted with pack mules, pickaxes, and rugged prospectors.
However, it may surprise you to learn that today’s mining industry is precisely the opposite in almost every respect. It’s high-tech, efficient, and safe.
This is partially because modern mining companies are deploying the latest in sensor and cloud technology. These connected mines are improving the extraction process and workers’ safety while also boosting productivity.
Today’s infographic comes to us from Natural Resources Canada and discusses how this sensor and cloud technology can be integrated into the extractive process.
What is Smart Mining?
A connected mine uses data from sensor technology to effectively manage underground and pit mining operations.
“Any mining operation today will have in the thousands or hundreds of thousands of sensors capturing in real time a vast swath of data.”
– Mukani Moyo, McKinsey Senior Expert (Source)
From a single application on a mobile device, supervisors at mine sites can now receive alerts via SMS, email or in-app notifications. This helps them react to critical problems in real-time and maximize productivity.
In addition, advanced data analytics can be applied to the raw data to create insights, visualizations, and recommendations. This information is delivered to mine managers and employees in real-time on their mobile devices.
Case Study: Smart Solutions in Practice
Dundee Precious Metals was one of the first companies to bring wireless networks into an underground mine. The company used RFID and Wi-Fi to monitor the location of equipment and people. The networks also allowed personnel to stay connected to the surface.
Once the networks were installed, communication was reliable and instantaneous – even almost 2,000 feet underground at the bottom of the mine. Workers could bring laptops and smartphones into the mine to stay connected to personnel and software on the surface.
With an RFID chip on every vehicle, machine, and person, managers can see the location of everyone and everything in the mine. This helps prevent accidents and breakdowns, and streamlines operations in real-time.
There are also environmental and cost-saving benefits. Using location data, an automated ventilation system can respond and minimize energy consumption.
Fans turn on and off as miners enter or leave an area. In addition, fan speeds adjust when machines or vehicles are running nearby to ensure that emissions are properly vented. This could drastically reduce a mine’s energy requirements.
Changing the Nature of Work: Remote Working
These smart mining solutions are reducing the risks miners face and creating new opportunities for a tech-savvy generation.
Remote mine locations that revolve around shift work can place stress on workers and their families. With a connected infrastructure, mine employees and managers can monitor operations at a distant office.
There will always be a need for workers on site, but connected technology can create some town-based career opportunities and help stabilize families.
A Sustainable Future for Mining
This is just the beginning.
Over time, data from sensor technology and cloud software, will reveal insights that could help develop sustainable mining operations.
By minimizing their negative impacts, mining companies will be able to responsibly deliver the materials the modern world needs.
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.
