Mineral-Resource Specialists
Mineral resource specialists examine the geologic and economic aspects of mineral resources. These specialists research the genesis and geologic setting of deposits, study the distribution of elements in the earth, and conduct assessments for undiscovered mineral resources. Resource specialists can answer questions related to the geologic aspects of mineral resources and exploration.
