Tosca Mining Corporation, (TSQ.V; US:TSMNF; FSE:TQ4), announces that drilling has commenced on its Red Hills Molybdenum-Copper project, located in Presidio County, Texas.


The purpose of the 4000 meter drill program is to:

1. Verify previous drilling within a near-surface copper blanket and to collect samples for metallurgical recovery test work, previous drilling had established a noncompliant historic resource of 17 million tonnes at .35% copper.

2. Carry out a preliminary assessment of a separate high-grade copper zone discovered by previous operators, who reported three intersections ranging from 6.12% copper to 9.09% copper over 21 meters and 33.5 meters respectively

3. Drill deeper holes, adjacent to a number of short historical drill holes that ended in strong molybdenum mineralization, and

4. Test for extensions of the molybdenum system. The deepest historical hole (Duval 7) was drilled to a vertical depth of 2106 feet (642 meters), averaged 0.076% Mo throughout

Note that in this news release all reference to previous studies, drill results and resource estimates is based on historic information. Since a qualified person has not done sufficient work to verify the historical data and estimates, the historical data and estimates should not be relied upon.
