Red Back Announces Major Expansion Plans for Tasiast Gold Mine in Mauritania

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Dec. 3, 2007) - Red Back Mining Inc. (TSX:RBI) (the "Company" or "Red Back") is pleased to provide an update on its 100% owned Tasiast Gold Mine in Mauritania.

Red Back successfully completed the purchase of Tasiast on August 2, 2007. Commissioning of the Tasiast plant is continuing with commercial production on track for January, 2008. The plant is currently operating on a batch basis awaiting the installation of new crushers. The new crushers have been ordered, are on route to site, and will be installed in December, 2007.

Since the Company took ownership of Tasiast, 148,000 tonnes of ore have been batch treated at a head grade of 4.44g/t and 96% recovery, resulting in production of 20,138 ounces of gold. It is anticipated that approximately 23,000 ounces will be produced by year end. Going forward, budgeted production at Tasiast for 2008 is 100,000 to 110,000 ounces.

Based on positive results from the ongoing resource conversion drill program, the Board of Directors of Red Back recently approved an expansion of the Tasiast plant from 1 million tonnes per annum (mtpa) to approximately 1.8 mtpa. Orders have now been placed for long lead time items, including a second ball mill and related equipment. This equipment is scheduled to arrive at site in the third quarter of 2008. Upon completion, expanded operations at Tasiast are expected to produce +180,000 ounces per annum. Combined with the approved expansion at the Chirano Mine in Ghana (news release dated November 21, 2007), Red Back's production will grow to +400,000 ounces of gold per annum in 2010.

Exploration at Tasiast is currently focussed on an 18,000m RC drill program aimed at infill and extension of the main Piment Zone. This program will be complete in February, 2008 and a new resource estimate will be reported. The Company expects to release the updated resource estimate by the end of the first quarter, 2008.
