Gold exploration company Serabi Mining has commenced a ground-based geophysical survey comprised of over 70km of induced polarisation (IP) at the Jardim do Ouro project in Brazil.

The surveyed areas cover the remaining priority anomalies from the initial airborne geophysical survey undertaken by the company in 2008, the Jamanxim and Calico prospects, being two new areas identified from the additional airborne survey undertaken earlier in 2011.

While it was originally envisaged to undertake IP over the remaining priority targets from the 2008 airborne survey, Serabi has in the light of its drilling success extended the survey and in particular to encompass the Espeto prospect following the success of drill-hole PDD470, the company said.

The positive drilling results at the Currutela prospect, along with re-processing of aeromagnetic data, showed the potential for structural continuity between Currutela and the existing Palito gold resource extending over some 1.6km.

The potential for structural and mineralized continuity was enhanced by the intersection in PDD470 of multiple zones of hydrothermally altered granite, similar to previously reported intercepts at Palito and Currutela, the company said.

PDD 470 is the first drill hole into the Espeto target that lies along strike to the southwest of Palito about midway between Currutela and Palito.

The company continues drilling with two drilling rigs on the Phase 1 discovery drilling program at Currutela, Lazaro, Pele and Tatu targets.
