Diamond Core Drilling Explained: Why It’s the Gold Standard for Mineral Exploration

Diamond core drilling rig operating at a mineral exploration site in Indonesia

Mining project begins with one essential question: what is actually beneath the surface? While geological mapping, geochemical sampling, and geophysical surveys can identify promising exploration targets, they cannot provide direct physical evidence of the rocks below ground. At some point, exploration teams need to recover actual rock samples to confirm geological interpretations, evaluate mineralization, and […]

When Should You Use a CSAMT Survey? Key Applications in Modern Mineral Exploration

Geophysicists conducting a CSAMT Survey in a mineral exploration project in Indonesia to map deep geological structures before drilling

Every successful mineral exploration project begins with one critical question: where should we drill? Drilling provides the most direct evidence of mineralization, but it is also one of the most expensive stages of exploration. Before committing significant resources to a drilling program, exploration companies need reliable subsurface information that reduces uncertainty and improves confidence in […]

CSAMT vs Resistivity Survey: Understanding the Best Choice for Deep Mineral Exploration

Comparison of a CSAMT Survey and Electrical Resistivity Tomography (ERT) survey used for mineral exploration in Indonesia, showing deep structural imaging versus shallow subsurface mapping

Selecting the right geophysical survey method is one of the most important decisions in any mineral exploration program. Before investing in drilling, exploration companies need reliable subsurface data to understand geological conditions, identify promising targets, and reduce exploration risk. Among the many geophysical techniques available today, two methods are frequently discussed for resistivity imaging: the […]
