Exploration is the process of searching for and assessing mineral resources, aimed at identifying, defining, and evaluating the potential of mineral reserves in a specific area. This activity includes the following subfields:

◆ Exploration Management
Comprehensive management of all aspects of exploration activities, including planning, organizing, and controlling resources.

◆ Topographic Mapping
Pembuatan peta bentuk permukaan bumi untuk mengidentifikasi karakteristik fisik yang berpengaruh terhadap eksplorasi dan kegiatan penambangan.

◆ Geological Mapping
Preparing maps that depict rock types, geological structures, and relationships between rock units to assess mineral potential and geological conditions of an area.

◆ Geochemistry
Studying chemical elements in rocks, soils, and water to analyze geological processes and detect potential mineral content.

◆ Geophysics
Applying physical methods such as gravity and seismic surveys to understand subsurface structures and detect mineral resources without direct excavation.

◆ Subsurface Survey
Techniques used to reveal geological conditions below the surface, including rock formations and structures.

◆ Geotechnical Studies
Investigating the physical and mechanical properties of soil and rock as a basis for engineering or mining infrastructure design.

◆ Exploration Drilling
Drilling activities to obtain subsurface samples for laboratory analysis.

◆ Exploration Sampling 
Creating geological visual models from collected data, used to design further exploration strategies.

◆ Resource and Reserve Estimation
Quantitative evaluation of the amount of mineable mineral resources and reserves based on gathered exploration data.
