Geological Report on Chrome Ore Mine
As reported by Gulf Mining onsite mining engineer, the chromite grade varies from 26% to 34% Cr2O3 content. Chromite does not intrude deep into the harzburgite and globally the contact can be considered as rapid. This type of structural contact suggests that the chromite pods deformed into the fault area in the already crystallized harzburgite.
