What Is Mineral Exploration? Finding Mineral Resources

If you own land or are curious about underground resources, knowing how and when to explore for minerals is essential. Mineral exploration is a process that helps landowners and investors discover mineral deposits, plan safe mining operations, and understand their options when they discover minerals, oil, or gas.

Thanks to technological advancements, mineral extraction and exploration projects are now more precise, efficient, and environmentally friendly. Keep reading to learn more about mineral exploration.

The Mineral Exploration Process

Mineral exploration is a careful way of searching for mineral deposits beneath the surface. It requires planning, scientific tests, and checks to understand what may lie underground. Here’s what the exploration process involves:

‍

1. Geological Mapping

This is the process of studying the land and recording its features. It is part of the early stage exploration process. Once the study is done and recorded, exploration companies or geologists use the information to create geological maps, which help to identify areas with potential mineral deposits.

‍

2. Remote Sensing

Remote sensing uses satellites and aerial images to spot changes in land, vegetation, and rock types. These signals can hint at minerals beneath the surface and help geologists to focus their surveys and drilling.

‍

3. Geochemical and Geophysical Surveys

After mapping the land, geologists use geochemical and geophysical surveys to pinpoint where minerals are most likely to be found. This is done to focus exploration on the areas with the highest potential. Geochemical surveys check rocks, soils, and sediments for unusual elements, while geophysical surveys detect changes in the Earth's physical properties.

‍

4. Core Drilling

Core drilling is one of the most important steps. It involves drilling deep into the ground to extract cylindrical rock samples called cores. These cores are examined in labs to determine the type of minerals present, their concentration, and the structure of the deposit. Core drilling provides the first direct evidence of what lies underground and helps estimate whether the minerals are worth mining.

‍

5. Trenching and Pitting

Trenching and pitting are used to study minerals closer to the surface. Trenching involves digging long, narrow channels to expose rock layers, while pitting digs small, shallow holes to collect soil and rock samples. These methods give geologists a clearer picture of how the minerals are distributed near the surface and complement the information gained from core samples.

‍

6. Resource Modeling and De-Risking

After collecting samples and survey data, geologists create 3D models of the deposit. These models show where minerals are concentrated and how large the potential mineral deposit might be. De-risking involves evaluating technical, environmental, and financial risks. This step confirms that the project is safe and economically practical before moving forward to mining.

‍

7. Environmental and Social Considerations

Mineral exploration can affect land, water, and wildlife, so careful planning is essential. Environmental science assessments are conducted to minimize impacts. Measures like controlling pollution, recycling water, and restoring land after exploration help to make sure that exploration activities are responsible and sustainable.

‍

8. Final Production Decision

Once all the data is collected, analyzed, and the risks are assessed, a decision is made about whether to move forward with mining. If the decision is approved, the mining company will design and build the mine. Once the mine has been built, production begins.

Essential Exploration Technology

Technological advancements have revolutionized mineral exploration activities by making them faster, smarter, and more precise. These advancements have made it easier for geologists to find out what lies beneath the surface, changing the oil, gas, and mining industries. Below are some essential technologies for mineral exploration:

‍

Remote Sensing Technologies

• Satellite Imagery – This technology is used for broad-scale geological mapping and identifying mineral signatures.
• Aerial Photography – This photography helps to observe surface features.
• Hyperspectral Imaging – Imaging captures hundreds of spectral bands that can be used to map different rock types and alteration zones.
• LiDAR – This technology uses laser pulses to create precise topographical maps, especially in forested areas.

‍

Geophysical Methods

• Magnetic Surveys – This technology helps to detect variations in the Earth’s magnetic field that are caused by mineral deposits.
• Gravity Surveys – This survey detects subsurface density variations to locate heavy minerals.
• Electrical Resistivity Surveys – With this survey, geologists can measure how electricity flows through rocks to identify mineralised zones.
• Seismic Methods – This method helps to analyze wave behavior that explains subsurface structures.

‍

Geochemical Analysis

• Soil Sampling – This method uses systematic surveys to detect geochemical anomalies.
• Stream Sediment Surveys – This method analyzes materials transported by water to identify mineralization.
• Portable XRF Analysers – This technology provides rapid, real-time chemical composition analysis in the field.
• Advanced Core Processing – This technology helps with systematic handling and analysis of samples for reliable data.

‍

Drilling Technologies

• Diamond Drilling – This method produces high-quality core samples that preserve the rock’s structure.
• Reverse Circulation Drilling – This drilling provides fast, continuous rock chip samples that are great for initial exploration.‍
• Sonic Drilling – This method uses high-frequency vibrations to drill through challenging ground conditions with minimal sample disturbance.

Determining the Right Time for Mineral Exploration Projects

Starting a mineral exploration project at the right time is important for success. Here’s how to determine the right time for mineral exploration on your property:

• You've confirmed that you legally own the mineral rights to the property. Without this, exploration and extraction cannot proceed.
• You have evidence that valuable minerals, oil, or gas may be present underground. This might include nearby extraction sites or surface signs.
• You've verified that the market for mineral rights is favorable and that exploration and extraction will be worthwhile.

‍

What To Do if You Find Mineral Resources on Your Property

Just because you found mineral resources on your property doesn't necessarily mean that they can be produced and sold profitably. Here's what to do once you find these resources:

‍

1. Don’t Assume Immediate Wealth

Surface signs like oil seepage or residue might hint at underground reserves, but they don’t guarantee a large or commercially viable deposit. It could be heavy oil, oil sands, or substances unrelated to oil production.

‍

2. Get Expert Assessment

To properly identify oil on your property, hire a geologist or petroleum engineer. They can test hydrocarbon levels, study the reservoir rock, and determine whether your land contains oil or gas-rich formations.

‍

3. Check Your Mineral, Oil, and Gas Rights

Owning the land doesn’t always mean you own what lies beneath. A lawyer can help clarify your legal rights before any exploration or drilling begins.

‍

4. Consult State Oil and Gas Authorities

State agencies, like the Texas Railroad Commission, regulate drilling and can guide you on how to safely and legally identify oil and gas resources on your land.

‍

5. Explore Your Options

If your property does have oil and gas, you can lease, drill, or sell your mineral rights. A mineral broker like The Mineral Auction helps landowners find serious buyers, sell mineral rights, and get the most profitable outcome through competitive bidding.
