Rock composed of muscovite and quartz having as mineral magnetite Specularite traits and

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

to 5.33 g / cm³, with ITF 1.319 g / cm³ and with CNG 1.896 g / cm³;

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.
