Minerals Exploration

AGI Surveys for Mineral Exploration are used in grass-roots exploration for a variety of mineral deposit types as well as mine site characterization studies. AGI’s Passive Sampler detects the volatile organic and inorganic compounds emitted by these mineral deposits in a parts-per-billion range. Using sensitive gas chromatography and mass spectroscopy, combined with Amplified Geochemical Imaging techniques, a probability map is constructed, helping to focus exploration efforts.

Gas chromatography/mass spectroscopy (GC/MS) and gas chromatography/atomic emission detection (GC/AED) analysis yields sensitive, compound-specific results that are used in identifying sources of mineralization:

  • About 90 compounds – through C20
  • Aliphatics
  • Aromatics
  • Oxygenated compounds
  • Inorganic and sulfur compounds
  • H2S Hydrogen Sulfide
  • S8 Molecular Sulfur
  • (CH3)2S Dimethylsulfide
  • CS2 Carbon disulfide
  • COS Carbonal sulfide
  • SO2 Sulfur dioxide
  • Mercury
Geochemical modeling and interpretation differentiates vapor signatures from oxidizing mineralization from those associated with vegetation, host rock, or shallow pollution.
The AGI Passive Sampler (AGI Module) allows for the direct detection of organic, organometal(loid) and inorganic compounds at the surface through hundreds of feet of post mineralization cover.
