===Mineral discovery===
Mineral discovery can be made from research of mineral maps, academic geological reports, or government geological reports. Other sources of information include property [[assay]]s and local word of mouth. Mineral research usually includes sampling and analysing sediments, soil, and drill cores. Soil sampling and analysis is one of the most popular mineral exploration tools.<ref>Martins-Ferreira, M. A. C., Campos, J. E. G., & Pires, A. C. B. (2017).
