Tosca Drills 362.4 Metres of 0.089% Mo, Including 253 Metres of 0.1% Mo in Hole TMC-25 and 301.4 Metres of 0.09% Mo Including 42.4 Metres of 0.16% Mo in Hole TMC-29

Tosca Mining Corporation (TSQ.V; US: TSMNF; FSE:TQ4) (Pink Sheets: TSMNF) today announced it has received assay results for the remaining 13 holes from its 4,873 metre (16,000 ft.) phase two diamond drill programcarried out at the Red Hills Molybdenum-Copper project, located in Presidio County, Texas.

In reviewing the results of the 2011 drill program, Dr Sadek El-Alfy, Chairman and CEO of the company comments; 'the drill program has successfully verified historic drill results of the shallowCopper-Molybdenum cap and confirmed the presence of a deeper well mineralized Molybdenum Porphyry deposit. The 2011 program encountered numerous thick mineralized intervals with grades in the 0.07% to 0.1% Mo range, and established the presence of elevated Rhenium content at RedHills. The Molybdenum grades are similar and in some cases higher than those of projects currently considered of potential economic interest.'

The results of 21 holes drilled through the copper/moly cap in Tosca′s 2011 drill program give a weighted average grade of 0.39 % Cu over acore length of 113 feet (34.5 m). Since the copper cap is subhorizontal, the average core length can be interpreted as being approximately equivalent to true width. The copper/moly cap is crescent shaped, approximately 4,000 feet (1220 metres) long and 400 feet (122 m) to 1000 feet (305 m) wide.

All of the holes except TMC-25 and 29 - 31 were short vertical holes drilled to penetrate the shallow copper-molybdenum cap overlying the much larger molybdenum porphyry system. All the short holes intersected intervals containing chalcocite mineralization and accompanyingmolybdenite -bearing veinlets. The grade of the mineralized intercepts from the copper cap vary from 0.23 % Cu over 40 feet (12.2 m) in holeTMC-19 to 0.61% Cu over 236 feet (71.9 m) in hole TMC-25. The molybdenum grades accompanying copper mineralization range from 0.026% Mo in hole TMC-20 to 0.073 % Mo in hole TMC-23. Copper mineralization was alsoencountered in holes TMC-30 and 31, the best interval grading 1.46% Cu over 18.5 feet (5.6 m).

The two holes (TMC-25 and TMC 29) drilled through the copper-molybdenumcap to test the deep molybdenum system returned excellent grades from top to bottom. TMC-29 was an angle hole drilled to check thedistribution of deep molybdenum mineralization along the west end of the deposit.

Hole TMC-25 intersected 1189 feet (362.4 m) averaging 0.089% Mo including 830 feet (253 m) of 0.1% Mo from 359 feet (109.8 m) to the bottom of the hole. Hole TMC-29 cut 989 feet (301.4 m) averaging 0.09 % Mo including 139 feet (42.4 m) of 0.16% Mo. As shown in the accompanying table, significant rhenium concentrations occur in many holes (e.g 580 ppb Re over 830 feet (253 m) in hole TMC-25, 945 ppb Re over 100 feet (30.5 m) in hole TMC-25 and 808 ppb Re over 71 feet (21.1 m) in hole TMC-28).

The results of holes TMC -19 to 31 are summarized below and their locations can be found at www.toscamining.com/i/maps/drillplan.

** The rhenium averages include intervals with Re contents above thelaboratory upper detection limit of 1,000 ppb Re. The figure of 1,000 ppb rhenium was used in calculating the averages.


The Company is currently working with Mine Development Associates ofReno Nevada on preparing a new resource estimate, which is expected to be completed by year end.

In parallel, The Company is working with Metcon Laboratories in Tucson Arizona, on establishing the flotation parameters to producing saleable Copper and Molybdenum concentrates, with results also expected by year end.


QA/QC

All analytical work was carried out at Skyline Assayers and Laboratories ('Skyline) in Tucson, Arizona. Copper and molybdenum were analyzed by ICP/OES. Rhenium values were derived by Aqua Regia leachanalyzed by ICP/MS.Skyline is an ISO/17025 accredited laboratory. Skyline monitors quality control through the introduction of blanks, standards and duplicates. In addition, Tosca′s employees routinely insert blanks and standards in the sample stream.
