Rock composed of muscovite and quartz having as mineral magnetite Specularite traits and
kyanite.
Itabirites rating based only on competence is consistent with the observed chemical
uniformity in the drill samples. Differentiation between itabirites and ferruginous
quartzite suggests that it may be appropriate separation of itabirites for its enrichment in
iron.

Density tests were not made in drill core samples.
BHP did not equalize density of the results of tests with the chemical analysis of the samples.
Apparently there is a mismatch between the lithologic classification and the results of the density tests. For example: ITC

Tests with sand bottle results showed very low compared with the water displacement method.
The ob.dos values for brittle rocks are very low compared to the amounts normally found in banded iron formations of the
QF.
It is suggested that data must go through a more careful review.
