Mustang Drilling Extends Copper Nickel Mineralization to Depth at Mayville

TORONTO, ONTARIO--(Marketwire - July 17, 2012) - Mustang Minerals Corp. (TSX VENTURE:MUM)(FRANKFURT:NJF) ("Mustang" or the "Company") today announced further drill results from the Mayville Property M2 Zone in southeast Manitoba, approximately 2 hours northeast of Winnipeg. Results confirm that the mineralization continues to depth along the west part of the M2 Zone. The Company is extremely encouraged by the significant zones of near surface mineralization indicated by the widely spaced holes.

Drill holes MAY12-58, MAY12-56 and MAY 12-49 were drilled at 200 meter centers over a strike length of 400 meters on the west part of the Mayville Deposit All three holes had mineralized intercepts below previous drilling on the respective sections. The results of the 2012 drilling are shown along with the 2006 drilling on the respective section. Mineralization is proximal to the volcanic gabbro contact with a number of the holes encountering massive sulfides with locally significantly higher grades. The mineralization remains open at depth.

The MAY12 series holes drilled recently are tabulated below with the MAY06 series holes (drilled in 2006) drilled on the respective section.

Discussion

The Company is pleased to see the continuation of the M2 Zone to greater depth on the west side of the M2 Deposit. A number of the drill holes have been surveyed with downhole EM and specific areas are targeted for follow up drilling. Notably, the wide zone of mineralization in MAY12-56 appears to have further potential to depth. Follow up drilling in the area of MAY12-57 is also planned. MAY12-57 was drilled on the eastern part of the deposit and intersected 25.0 meters which assayed 1.05% copper and 0.45% nickel.

The follow up drill program is planned to start in August 2012. Thereafter the Company anticipates completing a resource update for the Mayville Property targeting a significant resource upgrade. Follow up work will be funded from existing cash and working capital of the Company.

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.

Drill hole cross sections of the recently completed drill holes have been posted on 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.
