VANCOUVER, BRITISH COLUMBIA--(Marketwired - April 23, 2013) - Mineral Mountain Resources Ltd. ("Mineral Mountain" or the "Company") (TSX VENTURE:MMV)(OTCQX:MNRLF) is pleased to announce that preliminary data from the detailed Fugro HELITEM survey on the Holy Terror and Rochford Projects located southeast along strike of the formerly producing Homestake Mine in South Dakota, USA has been received.

Existing Mineralization Confirmed - New Targets Generated

The preliminary results for the HELITEM airborne magnetics and electromagnetics surveys from the Holy Terror and Rochford Projects have been received and are currently being reviewed. The HELITEM system is a proprietary technology belonging to Fugro Airborne Surveys and is a helicopter towed electromagnetic system designed to elicit a measurable geophysical response from conductive rocks. The majority of mineralization styles which host gold at both the Holy Terror and Rochford Projects are amenable to detection from this advanced geophysical system.

Based upon historical records, this is the first time that either area has been flown with any electromagnetic system or in such great detail. Initial assessments of the preliminary data indicate extremely positive correlations between the known gold mineralization at the Bullion, Keystone and Bismarck mines and the HELITEM responses. Application of these same signatures has yielded a plethora of new, previously unidentified target areas which will be ground-truthed and prospected by exploration staff in Q2 2013. This survey has yielded numerous significant new targets in undrilled areas of the properties.

In total, 997 line kilometres were flown at a resolution of 100 metre line spacings and have provided an amazing degree of detail for these project areas.

Commentary

About Mineral Mountain

Mineral Mountain Resources Ltd., through its wholly owned subsidiary Mineral Mountain Resources (SD) Inc., is focused on the exploration and, if warranted, development of its key assets, the Holy Terror Project in the Keystone Mining district and the 100%-owned Rochford Project both located along the Homestake Gold Trend in the southeastern part of the Black Hills of South Dakota. The Holy Terror Project is centered along the southwestern extension of the Homestake Gold Trend and covers approximately 4,000 acres straddling a major gold bearing structural corridor measuring about 15 km in strike length and 1.5 km in width. The Holy Terror and Rochford Projects contain 17 historic gold mines, eight of which within the Holy Terror Project. Production of these mines came from early Proterozoic gold mineralization associated with iron formation, and shear zones similar to the deposits at the former Homestake gold mine which, over 120 years, produced over 40 million ounces of gold. The Holy Terror Project is very well located near Rapid City where it can be easily accessed by a network of roads and has hydro-electricity and modern internet services to the drill site. As well, the area has a skilled labor force and is a low cost exploration area. South Dakota has low political risk and a jurisdiction that embraces mineral development.
