Ann: LIDAR Survey Identifies New Bauxite Targets, page-2

"These newly identified plateaux represent 65% of all the plateaux surface areaidentified at the target elevation on the three Minim Martap Project permits.To date, plateaux investigated at this elevation have consistently contained7m-15m thick, high-grade, low contaminant bauxite. The 70 new plateauxrepresents an additional area of 65.4km2 compared with the current resourcearea which is identified across 35.6km2.

Sampling and field mapping in conjunction with spatial analysis of the LiDARdata confirmed the relationship between elevation, geomorphology and thegrade of Al2O3, level of SiO2 contaminant and the thickness of the bauxite onone of the plateaus." (my bold)
