Machine learning (ML) and artificial intelligence (AI) technologies have made significant contributions to geoscience and mineral exploration in the mining industry, providing valuable tools and techniques for improving efficiency, accuracy, and effectiveness in various aspects of the exploration process. Here are some ways ML and AI benefit geoscience and mineral exploration in mining.
How ML and AI technologies benefit mineral exploration
1. Geological data analysis
Machine learning algorithms are able to quickly analyse vast data sets containing geological and geophysical data to identify patterns and anomalies that may indicate the presence of valuable minerals at a site. Data sets analysed may include core samples, seismic data, and geochemical data.
This helps geologists and exploration teams target their efforts and makes for effective and efficient mineral exploration.
2. They enable prospectivity mapping
Prospectivity maps consider various geological, geophysical, and remote sensing data layers to make predictions about mineral deposits in a location. ML models can be trained to create prospectivity maps, which highlight areas in a region with a higher likelihood of containing deposits of the minerals geologists and miners are searching for.
3. Help with prioritising exploration targets
ML algorithms can assist in selecting the most promising and important sites as targets for exploration. They do so by assessing the probability of success for each target based on historical data and geological characteristics. This helps exploration teams decide where to utilise their resources and focus their exploration efforts.
4. Streamline Mineral Identification
AI-based image analysis can aid geologists in quickly identifying the minerals in rock samples, streamlining the process of mineralogical analysis. This is particularly useful for onsite or real-time analysis.
5. Aid in geophysical data interpretation
Machine learning can be used in the interpretation of geophysical data, such as in gravity and magnetic surveys, by recognising subtle patterns and anomalies that may not be obvious to human geophysicists. This can lead to more accurate subsurface models of geophysical areas.
6. Assist teams in selecting sites as drill targets
ML algorithms can optimise drill target selection for companies by analysing historical drilling data and geological information. They then suggest the most promising locations for drilling to maximise the chances of discovering economically viable deposits.
7. Remote sensing abilities
AI can be used to analyse satellite and aerial imagery to identify geological features, alterations, and land cover changes associated with mineralisation. This can help identify new exploration targets and be used to monitor mining operations.
8. They can perform risk assessments
Machine learning-driven technologies can be used to assess geological and environmental risks associated with mineral exploration in a specific location. This enables teams to make informed decisions about whether carrying out exploration in the area is viable based on the possible impact it could have.
To sum things up, machine learning and artificial intelligence are powerful tools that can be used to enhance and optimise mineral exploration and geoscientists’ work. By leveraging these technologies, companies can reduce mineral exploration project risks, improve resource identification, and streamline their operations, ultimately leading to more sustainable, efficient, and effective mineral exploration.
