Mariana Commences Drilling at Sierra Blanca Gold-Silver Project, Santa Cruz Province, Argentina
VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 10/13/11 -- Mariana Resources Ltd. ('Mariana' or 'the Company') (TSX: MRY)(AIM: MARL), the AIM and TSX quoted exploration and development company focused in Argentina and Chile, is pleased to announce the commencement of its fourth drilling programme at the 70% owned Sierra Blanca Gold-Silver Project ('Sierra Blanca'), in southern Argentina (Figure 1). Sierra Blanca is located in the centre of the Deseado Massif gold-silver province. The programme comprises a minimum of 5,000 metres of diamond drilling aimed at targets derived from earlier drilling at Veta Chala and recently completed Induced Polarisation (IP) geophysics. Initial targets are veins and vein-breccias at Chala, Lucila and Vetarron further to the south-west. The Trafwe target is the gravel covered area between Chala and Lucila.
The drilling at Veta Chala will follow up previous promising 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. Recent IP surveying located a chargeability target at depth which could indicate sulphide mineralisation.
The Trafwe target, located on the two kilometres strike length between Chala and Lucila is outlined by a well defined linear magnetic low. This gravel covered area was also covered by the recent IP survey.
Drilling at Vetarron is planned to test coincident vein breccia zones and chargeability anomalies located in the northern part of the prospect.
Following the drilling campaign at Sierra Blanca the rig will return to the Company's flagship Las Calandrias Project in the eastern Deseado Massif.
Chairman John Horsburgh said today;
'This drilling campaign will test an impressive array of vein and vein-breccia targets, building on numerous robust looking intersections from drilling to date as well as some untested areas including the Trafwe target. Sierra Blanca clearly has excellent potential for vein-style epithermal gold-silver mineralisation.'
John Horsburgh, Chairman.

Quality Assurance/Quality Control
All technical information for the Company's Argentina projects is obtained and reported under a quality assurance and quality control (QA/QC) program. All samples are collected under the supervision of the Company geologists and dispatched via commercial transport to ALS Chemex laboratories in Mendoza, Argentina, and assayed in Chile. ALS Chemex's quality system complies with the requirements for the International Standards ISO 9001:2000 and ISO 17025: 1999. Samples returning greater than 10 g/t gold and/or greater than 100 g/t silver are assayed using gravimetric analyses.
Systematic assaying of sample duplicates and commercially prepared standards and blanks is performed for analytical reliability.

In southern Argentina, in addition to the Las Calandrias gold-silver discovery, the Company has the Sierra Blanca silver-gold prospect (70%); the Los Amigos joint venture (49%) with Hochschild Mining and a 160,000 Ha land package (100%) in the country. All of these projects are located in the Deseado Massif epithermal gold-silver district in mining-friendly Santa Cruz province of southern Argentina, which hosts four mines and several advanced projects. In Chile, Mariana has a joint venture with US based international mining and natural resources company Cliffs Natural Resources Inc., to explore for iron oxide-copper-gold deposits ('IOCG') in a 92,000 km2 area ('SCM Mariana Area') in north-central Chile along the highly prospective Atacama Fault Zone. The SCM Mariana Area includes the 44km2 Buenaventura and 46km2 Perro Chico IOCG projects. Mariana is also evaluating a number of gold-silver and copper-gold opportunities away from the Cliffs JV area, as part of a new initiative.
