Applications in Mineral Exploration

15 Sep 2013

Alteration minerals and assemblages, and the way in which they vary with respect to mineralisation, offer the explorer and mining professional important vectors towards mineralisation. In exploration, this influences the positioning of new drill holes or curtailing the progress of current holes to preserve precious exploration expenditure. In mining, ore and gangue are tracked while textural and mineralogical variables reveal key mechanical rock properties leading to consistent metallurgic and mine planning.

Inexperienced geologists can find discriminating different clay alteration species difficult. Even experienced geologists are often unable to determine the chemical variations within single alteration mineral species that provide meaningful exploration vectors. In both situations, consistency is key but difficult to achieve. For these reasons, spectral core logging is now becoming an integral part of drilling programmes.
