Four Drills Accelerate Ajax Program To Define Large Open Pit Resource

Vancouver, BC, November 26, 2007 Abacus Mining & Exploration Corp. (the "Company") is pleased to announce expansion of the mineralized zones at both the Ajax East and West areas of the Afton copper-gold project, near Kamloops British Columbia.  Results from fifteen holes reported below continue to demonstrate significant widths of copper-gold mineralization in an area that has had over 60,000 metres drilled by the Company since 2005.  Four drill rigs at Ajax will continue to provide additional data to potentially define a large open pit resource encompassing both Ajax pits, and areas in between.  The 43-101 compliant resource for the entire Ajax area is expected in the second quarter of 2008.

Ultimately, the Company plans to develop large scale surface mining operations at Afton, producing between 40,000 and 60,000 tonnes per day, with production commencing in early 2010.

Highlights

East Pit Drilling

• Hole AE-07-038 intercepts 98 metres averaging 0.63% copper and 0.40 g/t gold, and 54.74 metres of 0.91% copper and 0.56 g/t gold. 
• Hole AE-07-035 intercepts 36 metres of 0.51% copper and 0.27 g/t gold, and 39 metres of 0.48% copper and 0.38 g/t gold. The hole also includes a 129 metre interval of 0.17 g/t palladium. 
• Hole AE-07-039 intercepts 120 metres of 0.40% copper and 0.38 g/t gold.

West Pit Drilling

• Hole AW-07-059 intercepts 156 metres of 0.38% copper and 0.22 g/t gold which includes 111 metres of 0.45% copper and 0.28 g/t gold. 
• Hole AW-07-063 intercepts 48 metres of 0.49% copper and 0.27 g/t gold.  
• Holes AW-07-059 and 063 expand the mineralized zone at the west end of the pit at least 50 metres southwards.

About the Ajax area

The Company's 100% owned Ajax property comprises eight 100 percent owned Crown grants near Kamloops, B.C., comprising the historic East and West pits.  In addition, the Company has an interest in claims recently acquired from a joint-venture agreement signed with Newgold Inc.  The Ajax area lies nine kilometres southeast along an existing haul road from the Afton mill, shop facilities and tailings area which Abacus agreed to purchase in 2005 from Teck-Cominco.  In order to complete a compliant resource estimation of the entire Ajax area, the Company is using four drill rigs to complete a minimum of 60,000 feet of drilling (18,000 metres) on the ground surrounding the Ajax East and West area.  A 43-101 compliant resource estimate of the entire Ajax area is expected to be completed in the second quarter of 2008.  

About the Afton Property

The Afton properties belonging to the Company lie within a mining camp hosting a number of mined and un-mined alkalic copper-gold, porphyry style deposits.   Since 2002, Abacus has redefined several known deposits through expansion of down-dip and strike extensions. In doing so, the Company has completed over 360,000 feet (111,863 metres) of drilling. To date, the Company has developed NI 43-101 compliant indicated resources on the DM and Rainbow deposits, totaling 60.1 million tonnes and an inferred resource at the Ajax West deposit totaling 147,000,000 tonnes (all resources calculated at 0.20% copper cutoff).

During this time frame, the existing DM/Audra/Crescent compliant resource, completed in 2005, will also be recalculated, incorporating the recent 2006 and 2007 drilling.

Upon completion of all resource estimates, Abacus intends to progress their Afton project through preliminary economic studies and into feasibility during the second half of 2008.

New Drill Results

The following tables list the most recent drill results.  Intercept lengths are core lengths, which do not necessarily reflect true width. 

Eco Tech Laboratory Ltd. of Kamloops, B.C., has completed all of Abacus's analytical work on the project.  A quality-control program, using specific standards and blank samples is in place.  Robert G. Friesen, P.Geo. is the qualified person responsible for the design and conduct of the work performed.
