Exploration Tools and Techniques

GGL explores mineral properties using every available technology.

  • GGL’s proprietary database is made up of assessment reports of all diamond exploration activity in the NT for the last 15 years, government data, as well as data purchased through private sources.  (Exploration companies must submit assessment work of $2 per acre per year in order to keep their claims current.)

The GGL Database includes:

  • 300 GB of data in 29,000 map layers, representing geology, geophysics, topography, claims, bathymetry, airphotos, satellite images, sampling and drill sites, and man-made features.
  • Land Status - what lands are available and what claims are coming available.

GGL has also developed a proprietary software program that allows the Company to enter, effectively manage, and manipulate the data. 

GGL uses the data base to help define areas of interest for possible acquisition.  Once a claim is acquired, the database is enhanced with information from our own sampling, geophysical and geochemical surveys.  With all the information combined and accessible, we are able to identify potential drill targets.

Diamond claim sampling:

  • Samples originate on property.
    • 20 liter bucket filled with glacial till
    • position located and recorded using a GPS
    • notes taken
    • sample tagged
  • Samples sent to SRC mineralogical lab in Saskatchewan where they are concentrated.
  • Samples are reduced to a small vial of glacial till concentrate.
  • Selected indicator minerals are examined with a microprobe to determine the chemistry of the grains which will aid in determining the quality (diamond potential) of the kimberlite pipe.

Geophysical airborne and ground surveys:

  • Magnetic and electromagnetic surveys are used to help pinpoint kimberlite pipes.
  • Magnetic surveys measure the earth’s magnetic field.
  • Electromagnetic surveys generate an electromagnetic field in the earth and since an eroding kimberlite surface is often conductive, this type of survey can be conclusive.

Geophysical airborne and ground surveys are used in conjunction with ground sampling to explore for diamondiferous kimberlite pipes.
