[pdf] Exploration diamond drilling is used in the mining industry to probe the contents of known ore deposits and potential sites. By withdrawing a small diameter core of rock from the orebody, geologists can analyze the core by chemical assay and conduct petrologic, structural, and mineralogical studies of the rock. It is also often used in the geotechnical engineering industry for found. HistoryRodolphe Leschot is often cited as being the inventor of the first core bit in 1863. Early drilling opened up many new areas for mineral mining, and was related to a boom in mineral exploration in remote locations. B. .
