ODM MMSIM grain counts



Overburden Drilling Management - metamorphic and magmatic sulphide indicator mineral (MMSIM) grain counts.  The counts are specific to the 0.25-0.50 mm grain size.

General Methodology:

MMSIM picked grain counts for the 0.25-0.50 mm size fraction.  The counts are reported as a mix of actual and estimated grain counts, plus estimated percentages of the whole assemblage.  The percentage estimates are based on the assumption that 1 gram of the 0.25-0.50 mm size fraction contains approximately 10,000 grains.  The data reported by ODM have been somewhat simplified.  The simplifications include:

  • grouping sapphire and ruby together as corundum
  • ignoring colour differences between gahnite grains
