Tosca Mining Corp. (TSQ – TSX Venture, TQ4 – FWB), reported today it has completed the due diligence on the Red Hills Moly-Copper Project and has signed a formal agreement to purchase the 100% ownership of all mineral and surface rights of the property.  The agreement calls for payments of US$10,900,000 and the issuance of 2.1 million common shares to the sellers of the property over a five year period.  The sellers will retain a 2% net smelter return over the Red Hills property.

Ron Shenton, President of Tosca states “The company will now initiate field work leading to a drill program to verify historical drilling within the shallow copper-moly blanket, as well as deepen and verify previous drill holes in the moly zone. The data will be the basis of a 43-101 compliant report followed by a pre-economic assessment.”

The 2,880-acre Red Hills project lies along a seven kilometre mineral district characterized by significant occurrences of precious and base metals, including the Shafter-Presidio silver deposit.  Located 27 kilometres  north of the border town of Presidio which is served by US highway 67 and the South Orient Railroad, the property has access to water from adjoining properties and a major power line serves the Shafter silver property located seven kilometres east of Red Hills.

As described in the company’s news release dated March 2, 2011, the Red Hills project consists of a large molybdenum porphyry system overlain a by a copper (chalcosite) enrichment blanket developed below the oxide-sulphide transition zone.  Eighty eight holes were drilled on the property between 1955 and 1972.  This work led to the identification of a non-43-101 compliant resource of 17 milliontons grading 0.35 Cu% with associated moly mineralization in the shallow copper blanket. The previous activity also led  to the discovery of a linear trend of high grade copper mineralization defined by three vertical holes which included 33.55 metres of 9.09 % Cu. Based on historic drilling, the molybdenum mineralization occurs within a horseshoe shaped area measuring 1,000 m x 200 m and is open in two directions and at depth. Although many of the holes drilled in the molybdenum system were stopped in mineralization at shallow depths, the deeper holes were mineralized throughout (e.g. hole Duval 07: 642 metres @ 0.076% Mo).

Note a qualified person has not done sufficient work to classify the historical estimate as current mineral resources, the issuer is not treating the historical estimate as current mineral resources and the historical estimate should not be relied upon
