The program comprises a minimum of 5,000m of diamond drilling aimed at targets derived from earlier drilling at Veta Chala and recently completed induced polarisation geophysics.

Initial targets are veins and vein-breccias at Chala, Lucila and Vetarron further to the south-west, and the Trafwe target is the gravel covered area between Chala and Lucila.

Drilling at Veta Chala will follow up previous intersections at Achen, Chala Central and Chala Splay such as 20.3m @ 1.5 g/t gold (Au) and 34 g/t silver (Ag) from 121.7m including 2.65m @ 6.8 g/t Au and 23 g/t Ag from 135.6m in Hole CHD71; and in CHD61, 28.7m @ 1.4 g/t Au, 11.5 g/t Ag from 85.0m, including 3.0m @ 9.5 g/t Au, 28 g/t Ag from 87.0m, both from Achen.

At Lucila, shallow drilling in 2008 intersected a five metre thick quartz vein with anomalous gold and silver values, and recent IP surveying located a chargeability target at depth which could indicate sulphide mineralisation.

The Trafwe target, located on the 2km strike length between Chala and Lucila, is outlined by a well defined linear magnetic low, and this gravel covered area was also covered by the recent IP survey.

According to Mariana Resources, drilling at Vetarron is planned to test coincident vein breccia zones and chargeability anomalies located in the northern part of the prospect.

The Sierra Blanca project is located in the centre of the Deseado Massif gold-silver province.
