Abacus Looks at DM Zone as a Complement to the Multi Pit Mining Plan

VANCOUVER, BRITISH COLUMBIA--(Marketwire - Dec. 11, 2007) - Abacus Mining & Exploration Corp. (TSX VENTURE:AME) (the "Company") is pleased to announce diamond drill results from the first 15 holes of a 32 hole, 29,875 foot (9,106 metre) program on its DM/Audra/Crescent ("DM") deposit, which lies 1.5 kilometres east of the old Afton mine and infrastructure. The focus of the drilling at the DM Zone is to upgrade and constrain the 43-101 compliant resource completed in 2005. Since the DM resource was calculated, the Company has completed an additional 51 drill holes totaling 53,359 feet (16,264 metres) on the deposit during 2006 and 2007. The Company plans to update the 43-101 compliant resource estimation on the DM zone by second quarter of 2008.

"The DM zone's resource is only 1.5 kilometres from the existing infrastructure and has a low strip ratio, which enables Abacus to look at the DM deposit as an important component of a potential multiple pit mining plan at Afton. This complements and adds to the proposed 2010 production from Ajax and elsewhere," said Doug Fulcher President and CEO. "Additionally Abacus continues to expand the resources at the Afton Ajax camp with the large multi pit scenario as the focus moving forward."

DM Zone Highlights

- Hole DA-07-069 intersects 33.43 metres grading 0.56% copper and 0.33 g/t gold.

- Hole DA-07-056 intersects 24 metres grading 0.42% copper and 0.23 g/t gold within a wider interval grading 0.29% copper and 0.18 g/t gold over 108 metres.

- Hole DA-07-068 intersects 33 metres of 0.38% copper and 0.34 g/t gold.

The following tables list the most recent drill results from the DM zone. Intercept lengths are core lengths, which do not necessarily reflect true width. Section spacing is 30 metres. A drill hole plan map is available at www.amemining.com.

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 399,000 feet (121,618 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 tones 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.

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.

On Behalf of the Board,

ABACUS MINING AND EXPLORATION CORPORATION

Doug Fulcher, President and Chief Executive Officer
