TORONTO, ONTARIO -- (Marketwire) -- 06/14/12 -- Mustang Minerals Corp. (TSX VENTURE:MUM)(FRANKFURT:NJF) ("Mustang" or the "Company") today announced an update on its drilling activities at the Mayville Property M2 Zone in southeast Manitoba, approximately 2 hours northeast of Winnipeg. The Company recently completed a series of resource holes at Mayville focused on expanding the near surface resource of the Mayville Project to depth. Drill results for two holes which were drilled in the eastern part of the M2 Deposit are reported in this release. The importance of these holes is that:

1) Drill hole MAY12-43 extended the main zone of mineralization to depth.   
2) Drill hole MAY12-57 intersected a higher grade zone of mineralization    
   beneath previous drilled mineralization.                                 
     -  A target defined by recent borehole EM.                             
3) Drill hole MAY12-57 intersected PGM mineralization in the footwall rocks 
   to the M2 Cu-Ni Deposit.                                                 
     -  The PGE mineralization in the footwall of the M2 Cu-Ni deposit      
        represents a new exploration target.                                

The Mayville Intrusion hosts the M2 Zone resource which is a magmatic nickel copper system. Sulphide mineralization consists of chalcopyrite, pyrrhotite, pentlandite and pyrite and a variety of textures ranging from disseminated to locally massive. The M2 Deposit has a current strike length of over one kilometer and is open at depth. The current near surface resource is 9.2 million tonnes at 0.61% copper and 0.23% nickel.

Discussion

The mineralization in MAY12-57 appears to be part of a higher grade zone also intercepted by previous drill hole MAY05-16 (1.58% copper and 0.47% nickel over 14.8m) which was located approximately 75 meters down dip of MAY12-57. Borehole geophysics has outlined a 250m by 250m conductive plate which now is a significant exploration target for the Mayville Project. The drill intercept in MAY 2-57 is higher grade than the current resource average for the M2 Deposit. The mineralization in drill hole MAY12-57 starts at about 300m vertical depth.

MAY12-57 was also extended into the footwall for several hundred meters. At a depth of 508.2 meters it intercepted an interval of platinum group metals mineralization. The interval contained a one meter sub-interval assaying 2.3 g/t Au-Pt-Pd. The entire intercept assayed 1.1g/t Au-Pt-Pd over 7.7 meters.

The potential for a continuous zone of platinum group metals mineralization to the north of the Mayville M2 Zone is now an exploration target given its close proximity to the Mayville M2 Ni-Cu resource. The footwall host rock for the platinum group metals has been noted in other drill holes across the 1.2 km strike length of the M2 Deposit but for the most part remains untested. A sampling program of existing drill core from 2005 and 2006 is being designed to test this potential.

Drill hole results from other M2 Zone are pending from the central and western parts of the M2 Zone. Holes targeted the western part of the M2 Zone as the modeled resource on the west side is relatively shallow and there was no previous drilling at depth in this area.

The overall objective of the current drill program will be to result in a significant resource upgrade for the Mayville M2 Ni-Cu Deposit which is one of two near surface deposits in the Bird River Greenstone Belt controlled by Mustang.

The Company is also awaiting assays from drill holes at the PGM Zone on the Mayville Property which is approximately 1 km to the southeast of the Mayville M2 Zone.

A longsection of the M2 Deposit and sections and drill hole information have been posted at the Company website at www.mustangminerals.com.

QA/QC Program

All core samples are sent to Accurassay Laboratories in Thunder Bay, Ontario. Analysis is completed for nickel, copper, cobalt and silver using an Aqua Regia digestion followed by AAS/ICP finish. For gold, platinum and palladium, fire assay of 30g aliquots followed by combination fire assay and AAS finish is employed. Drill core is logged and split on the Makwa site by Mustang personnel with half the core retained and stored. Mustang implements a QA/QC program on drill core including inserting blanks, duplicates and commercial standards at regular intervals with all sample submissions to the laboratory.
