Mining

The mining industry presents many unique opportunities for geophysical applications that cannot be solved by ordinary characterization or monitoring methods alone.  HGI has proven itself time and again to be an  innovative and solutions oriented geophysical consulting, services  provider, and research organization dedicated to the mining industry.  HGI has also become a recognized leader in the application of geophysical methods for the exploration of mineral resources, characterization of engineered rock piles, liner leak services, environmental stewardship, reclamation, and abandoned mine lands.   Additionally, HGI has worked extensively on water resource problems, geotechnical applications, and enhanced recovery of metal from heaps.  For more detailed information regarding our mining services, please visit www.heapsolutions.com

Mining geophysics offers tools that can be used to supplement a drilling or mapping campaign to gain greater insight into the subsurface.

HGI’s most recent applications of geophysics at mine sites range from heap leach saturation mapping, pond liner leak location, fluid injection monitoring for enhanced recovery, to the mapping of subsurface controls on acid rock drainage (ARD).   However, we have conducted a wide array of projects that can be grouped accordingly:

Exploration:

• Mineral resource mapping

• Precious and base metals

• Structural mapping

• Geologic interpretation

Operations:

• Heap characterization

• Secondary recovery monitoring

• In-situ leaching

• Liner integrity

• Pond leak location

Environmental:

• Acid rock drainage mapping

• Contaminant source identification

• Recharge sources

• Corrective action monitoring

• Grout curtain installation monitoring

• Cap integrity monitoring

Reclamation:

• Abandoned mine land mapping

• Acid  rock drainage mapping

• Corrective action monitoring

• Cap integrity monitoring
