Minsud Resources Corp.: Exploration Update Chita North Porphyry Sector, Chita Valley Cu-Mo-Ag-Au Project, San Juan, Argentina

TORONTO, ONTARIO--(Marketwired - May 23, 2013) - Minsud Resources Corp. ("Minsud" or the "Company") (TSX VENTURE:MSR) announces exploration results from the Chita North Porphyry area of the Chita Valley diatreme volcanic vent/porphyry complex.

The following is an update on recent exploration work conducted on the Chita North sector of the Chita Valley Project (the Project") located in San Juan Province, Argentina. The Project is a large exploration stage diatreme volcanic vent/porphyry complex with classic alteration features, widespread porphyry style Cu-Mo-Ag-Au mineralization, and associated gold and silver-bearing polymetallic veins.

Exploration Work First Quarter 2013

The current exploration program represents a balance between systematic multidisciplinary exploration and prudent use of limited funding in a poor financial market. As a result Minsud is currently concentrating primarily on the continuation of systematic detailed geological mapping and alteration studies with selective surface sampling.

The strategy is to continue expanding the areas covered by detailed mapping to eventually include the entire Chita Valley Properties area. Lithological, alteration, structural and mineralization studies that initially focused on the Chinchillones and Chita South Porphyry areas are being expanded to include other nearby sectors (Chita North Porphyry, Breccias Ridge, Placetas Porphyry, Romina and Minas de Pinto) to eventually produce a coordinated exploration and mineral deposits model for the entire property.

Chita North Porphyry

A program of semi-continuous weathered surface bedrock sampling employing a combination of sawn channel samples and composite chip channel samples was completed in Q1 2013. Four semi-continuous sampling profiles were completed (NPry-13-01, 02, 03 and 05) with a total of 135 geochemical samples with a cumulative sampling length of 325 metres. All samples were submitted to the Alex Stewart (Assayers) Argentina S. A. laboratory in Mendoza, Argentina for preparation and analysis. The laboratory is certified to ISO-9001 international standards. All geochemical grab and channel rock samples were analyzed for Au by fire assay/ AA finish, 50 g, (Au4-50) plus a 39-element ICP scan (AR-39).

Sampling profiles NPry-13-01, 02 and 03 were designed to provide an initial evaluation of the substantial areas of jarosite-pyrite alteration near the porphyry-andesite contact zone. The generally NE oriented altered zone is characterized by concentrations of veins, breccias and stockworks. Trench NPry-13-05 which lies outside of the stronger alteration and mineralization is used to determine local geochemical background values.

In general the geochemical results indicate anomalous concentrations of gold, silver and copper over significant intervals. In comparison to the previously reported channel sampling from the Chita South porphyry area these elements generally occur in similar to somewhat higher concentrations at Chita North. Molybdenum values on the other hand are substantially lower in the areas sampled at Chita North. As a general rule due to surface leaching, copper values at surface usually understate the contents of the underlying supergene enrichment and primary mineralization zones.

It is emphasized that the areas sampled constitute a very small portion of the mapped mineralization and in turn the exposed bedrock areas represent a similarly small portion of the Chita North sector. Therefore the combined historical exploration (two widely spaced drill holes) and Minsud's three modest surface trenches do not adequately test the area's mineral potential for epithermal or porphyry deposit types.

Mr. Howard Coates, Professional Geoscientist, Director of the Company and a geological consultant, is a qualified person as defined by Canadian National Instrument 43-101. Mr. Coates visited the property and has read and approved the contents of this release. Mr. Coates states; "The early-stage detailed mapping, surface sampling programs and magnetometer survey work at Chita North continues to define the paleotectonic setting, mineralization models, structural features, alteration styles and general mineral deposit potential of the Chita North sector as well as the overall Chita Valley Project. These encouraging results indicate a need for further multidisciplinary exploration work in the area."

Carlos Massa Minsud´s President & CEO, states: "We defined a modest but effective exploration program more than one year ago to systematically explore the Chita Valley Project. Fortunately every new target area is extending the mineral potential frontier as initially hoped."
