fAST-logg
fAST-logg Borehole Logging System for Grade Control
fAST-logg is a tailored, site specific logging application to survey, map and evaluate orebodies for mining purposes based on the variation in physical properties of the orebody and host rocks.

Reach three accuracy levels
fAST-logg borehole logging in production phase can reach three accuracy levels depending on the orebody
- Quickly
detecting ore boundaries
- Locating favorable zone or key structure controlling orebody
- At best, delineating orebody with grade estimation
Increase cost efficiency
All the logging accuracy levels provide tools
- To minimize waste dilution and ore loss
To use less expensive percussion drilling instead of expensive core drilling
- To reduce sampling and assay costs
- To quickly receive information for stope planning or blasting
fAST-logg Borehole Logging System for Mineral Exploration
fAST-logg System also provides a versatile set of borehole probes for logging physical properties in mineral exploration holes.The fAST-logg borehole probes for exploration holes consist of
- Magnetic susceptibility
- Galvanic resistivity with electrode arrays: Wenner,
- Induced Polarization (IP)
- Inductive conductivity
- Gamma-Gamma density
- Natural Gamma-ray
- Gamma-ray spectrometer
