Red Back Mining Inc.: High Grades Intersected Between Pits at Chirano

VANCOUVER, BRITISH COLUMBIA--(CCNMatthews - March 15, 2007) - Red Back Mining Inc. (TSX:RBI) (the "Company" or "Red Back") is very pleased to report that recent infill drilling at the Chirano Gold Mine in Ghana, West Africa has intersected high grade mineralisation at depth between the Tano and Paboase open pits.

Hole CHRC923 is part of an ongoing resource optimization program at Chirano. As expected, the upper part of the hole confirmed previous drill results of 1-2g/t gold. However, the hole was extended to depth upon intersecting high grade material at 150m. Results from CHRC923 are reported below:



----------------------------------------------------------------------------
Hole ID From (m) To (m) Interval (m) Grade (g/t gold)
----------------------------------------------------------------------------
CHRC923 62 84 22 1.42
----------------------------------------------------------------------------

----------------------------------------------------------------------------
107 150 43 1.16

----------------------------------------------------------------------------
151 225 74 5.68
----------------------------------------------------------------------------
incl 168 188 20 9.99
----------------------------------------------------------------------------


True widths are estimated to be approximately 60% of drilled widths.

The 74m interval grading 5.68g/t (including 20m grading 9.99g/t) lies below the limit of previous drilling in this area, 100m below the current pit design and is 180m south of the main Tano orebody.

Commenting on the new discovery Richard Clark, President and CEO of the Company, stated, ""The discovery of high grade mineralisation between Tano and Paboase follows the recent high grade intercept below the Obra pit (17.1m grading 7.61g/t, News Release 21st February). The potential of these new discoveries is demonstrated by the size of the high grade orebody at Akwaaba (674,000 ounces Indicated resource plus 221,000 ounces Inferred resource - Hellman and Schofield, November 2006). More importantly, these intercepts confirm the potential of the Chirano Shear zone to host high grade ore bodies at depth and between existing surface deposits. Upon completion of the resource optimization program, by the end of March, these new discoveries will immediately be targeted for resource definition."
