ODM Indicator Mineral Picking-Kimberlite samples

Overburden Drilling Management Indicator mineral counts-Kimberlite samples. A portion (¼ to 1/16) of kimberlite samples are picked for 4 major indicator minerals including Cr-diopside, Cr-pyrope, Mg-ilmenite and chromite.

General Methodology:

Overburden Drilling Management indicator mineral picking. Only a portion (¼ to 1/16) of kimberlite samples is examined for indicator minerals under binocular microscopes due to the abundace of indicator minerals in kimberlites.  Grains are examined for pyrope, chrome diopside, ilmenite and chromite.  Grain identity is not confirmed by electron microprobe.
