Minsud Announces Exploration Results at La Rosita-Deseado Massif-Santa Cruz Province-Argentina

TORONTO, ONTARIO--(Marketwire - Aug. 15, 2012) - Minsud Resources Corp. ("Minsud" or the "Company") (TSX VENTURE:MSR) is pleased to announce the results of early stage exploration work conducted during Q1 and Q2 2012 on its 100% owned LA ROSITA Project, Santa Cruz Province, Patagonia Argentina. The work is the continuation of systematic multidisciplinary exploration designed to test a substantial (>6 km2) area of complex hydrothermal alteration that shows key attributes of Ag-Au bearing polymetallic vein systems and Ag-Au low-sulfidation systems. The La Rosita Project is located in the prolific Deseado Massif mining district some 25 km north of the Martha Mine and about 30 km northwest of the Manantial Espejo Mine.

An early stage exploration program was performed, including:

• a ground magnetometer survey covering some 16 km2 (320.3 line km),
• detailed surface geological mapping and at 1:2000 scale over an area of approximately 6 km2, and
• 3.5 line km of mechanical trenches (51 trenches) to define geological units, alteration features and as an initial test of potentially mineralized structures.
• About 22 km of bush road construction was carried out to allow easy access the main target areas.

The combined exploratory methods enabled the mapping of various styles and intensities of the classical alteration types as well as a variety of chalcedonic silica and carbonate veins, vein stockworks and breccias systems. The area exhibits a variety of overlapping styles of alteration, veining and mineralization. These enigmatic features indicate an extended temporal range of magmatic activity and potentially multiple stages of mineralization (Figure 1).

The 2012 trenches did not encounter any mineralization sections that might be considered commercially significant in grade or thickness. However, the trench analytical data has confirmed the existence of widespread areas of geochemically anomalous silver and gold as well as much larger zones of anomalous base metals (Cu, Pb, Zn) as well as the pathfinders mercury and arsenic. Additionally anomalous values of tungsten and antimony were encountered in the system. It is believed that the currently outlined 4,000 m of combined veins still have potential for the discovery of high grade Ag-Au deposits similar to those being mined in the region (Targets: Mogotes Hill, Maria Sol Veins and Breccia Hormiga). Additionally acid domes related to hydrothermal alteration and disseminated sulphides are believed to have potential for discovery of Ag-Au low grade/bulk tonnage mineralization (magnetic anomalies in the Mogotes Hill Target and acid domes related to the sub outcropping Maria Sol Target). Breccia complex systems that contain promising mineralization/alteration features have also been identified (Felices Pascuas Breccia and Eastern Red Breccias Targets) (Figure 2).

The magnetic survey and mapping program has defined a conjugate shear structural system, with maximum extensional effort coincident with the general strike of the outcropping mineralized veins. The magnetic survey also revealed three magnetic high features, possibly linked to mineralized acid domes underlying the Mogotes Hill target (Figure 3).

The combined features of lithology, structure, alteration, precious/base metal geochemistry, pathfinder element geochemistry, and magnetic features all indicate that the outcrops are possibly near or immediately above the boiling zone (Figure 4). The link between the main alteration system, the intrusion of acidic domes and shear stress field, create the right conditions for the formation of Ag-Au mineralization. The minor anomalies observed in precious and base metals (Table 1), as well as the strong distribution of pathfinders conform to the mineralization model, and indicate an optimum erosion level, with potential for a discovery within 300 meters of surface.

Exploration work carried out so far indicates the possible presence, at shallow depth, of an extensive low sulfidation epithermal system, similar to most deposits of the Deseado Massif. Minsud plans to continue with the systematic multidisciplinary approach to target definition. The next phase of target development will be an Induced Polarization/Resistivity survey preparatory to drill target definition.

Mr. Howard Coates, a Professional Geoscientist and a "Qualified Person" as defined by National Instrument 43-101, has visited the property and has read and approved the contents of this release. Mr. Coates, the Vice President (Exploration) and Director of the Company, states: "La Rosita is a very promising early stage exploration situation, although a lot of multidisciplinary work is required to test its mineral potential".

Carlos Massa, President & CEO of the Company, states: "We are continuing to systematically explore a property that is the product of the project generation skills of our in-house technical team. By advancing exploration at La Rosita we are diversifying risk across a broader project base and increasing the Company's chances of significant mineral deposit discovery."
