Mineraaliesploraatiossa, often referred to as mineral exploration, is the systematic search for ore deposits that hold significant economic value. The goal of this field is to locate new mineral resources or to evaluate existing ones, thereby informing decisions about drilling and mining operations. Exploration uses a combination of geological, geophysical, and geochemical methods to identify subsurface mineralization. Geological mapping and sampling provide foundational data, while geophysical techniques such as seismic surveying, magnetic and gravity measurements, and electrical resistivity mapping help model the Earth's subsurface structure. Geochemical surveys measure trace elements in soils, stream sediments, and biological samples to detect anomalous concentrations that may signify underlying ore bodies.

The exploration process usually begins with a desk-based assessment, integrating historical records, satellite imagery, and existing data. Fieldwork follows, involving reconnaissance drilling, trenching, and sampling at strategic locations. Early results guide more detailed work, culminating in the design of a resource model that estimates tonnage and grade. Technology has greatly expanded the scale and precision of exploration, with remote sensing, GIS, and machine learning models providing new tools for risk management and investment analysis.

Mineral exploration carries environmental and social responsibilities. Companies must conduct assessments of potential impacts on ecosystems, water resources, and local communities. Regulatory frameworks, such as the Environmental Impact Assessment (EIA), require mitigation plans and public participation. When conducted responsibly, mineral exploration can contribute to local economies, create jobs, and supply essential raw materials for manufacturing, energy, and technology industries, but it also demands rigorous stewardship to minimize ecological footprints and respect indigenous rights.
