In September 2006, and at the recommendation of Goldberg, the company Maping Ltda. carried out a low-resolution geophysics at the Lar group tenements, in order to determine the magnetic field response of possible magnetite and specularite bodies that could be associated with copper and gold mineralization. The above is not possible to determine on the surface due to the cover of sediments and colluvium. In addition, detect other geological features through magnetic anomalies, and thus be able to associate them with mineralized bodies of the IOCG (Iron Oxides Copper Gold) type.

The result of the geophysical study allowed the identification of two units, called Unit 1 and Unit 2 . The Unit 1 is associated with high magnetic anomalies which correlates to iron formations surface, possibly magnetite, and could be setting an IOCG deposit, the Unit 2 is instead associated with low magnetic anomalies, which minerals may have been transformed by a high temperature geothermal process, a product of which they have lost their magnetic properties, which is common in demagnetized or non-magnetic mineralized rocks, with structural implications.This unit configures an exploratory target of economic interest, of metals not associated with iron.

The study carried out by Goldberg , and based on the results presented above, recommends four activities , which are the development of an extensive geochemical study , a geological survey at 1: 10,000 scale and on the targets one at 1: 5,000 scale, a geophysical study of the gravimetric type on the targets of Unit 2, and, at the end of these activities, design a reverse air and diamond drilling campaign.
