Abacus' Ajax East Extension Area Drilling Highlights Potential for Starter Pit

VANCOUVER, BRITISH COLUMBIA--(Marketwire - March 15, 2010) - Abacus Mining & Exploration Corp. ("Abacus" or the "Company") (TSX VENTURE:AME) is pleased to announce results from diamond drilling in the Ajax East Extension ("AEE") area, a fault offset extension of the copper-gold rich Ajax deposit, near Kamloops, British Columbia. The drill holes targeted near-surface higher grade copper-gold mineralization with the intent to upgrade previously existing NI 43-101 compliant mineral resources in the AEE (announced June 22, 2009), and to explore the potential for hosting a "starter pit", which could be delineated for the ongoing Prefeasibility Study. The Ajax deposit is currently estimated to contain approximately 2.9 billion pounds copper and 2.7 million ounces gold with the potential for a 60,000 ton per day mining operation producing an average of 110 million pounds of copper and 100,000 ounces of gold in concentrate annually over a 23 year mine life. Both the AEE and Ajax area is 100 per cent owned by Abacus.

The drilling occurs within a 500 metre by 200 metre zone of favourable Sugarloaf Diorite between the AEE and Ajax deposit. Fifteen relatively short vertical drill holes were completed on a 50 metre - 100 metre grid pattern while three deeper inclined holes tested the main AEE offset zone for continuity of deeper copper-gold mineralization, and to convert inferred resources into measured and/or indicated status. In total, 3,616 metres (11,862 feet) of drilling was completed in this phase.

Doug Fulcher, President of Abacus stated, "We are extremely pleased with the outcome of this phase of drilling. The results demonstrate the presence of a zone or zones of near-surface copper-gold mineralization that when combined with previous near-surface intercepts, may host a "starter pit" that could supply early, higher-grade mill feed, and potentially enhance the economics of the Ajax deposit. We are also encouraged that deep drilling in the AEE confirms the future 'blue-sky' potential as the entire Ajax deposit remains open at depth."

Drill Highlights

Grid Drilling

- Hole AM-10-044 intersects 71 metres (232.9 feet) averaging 0.43% copper and 0.13 g/t gold; which includes 29 metres (95.1 feet) averaging 0.64% copper and 0.20 g/t gold, and also includes 14 metres (45.9 feet) grading 1.09% copper and 0.36 g/t gold. The top of the mineralized intercept was 31 metres (101.7 feet) below surface.

- Hole AM-10-039 intersects 72.6 metres (238.2 feet) averaging 0.33% copper and 0.22 g/t gold; including 27 metres (88.6 feet) averaging 0.43%, copper and 0.30 g/t gold. The top of the mineralized intercept was 19 metres (62.3 feet) below surface.

Deep Drilling

- Hole AM-09-034, which was drilled to 441.05 metres (1447 feet) last year, was deepened 252.68 metres (829 feet) this year for a total depth of 693.73 metres (2276 feet). Besides the intercepts reported in the last news release, the lengthened portion of the hole allows a significant mineralized interval to be restated as 250.25 metres (821 feet) averaging 0.33% copper and 0.27 g/t gold; which includes a 73 metre (239.5 feet) intercept averaging 0.51% copper and 0.52 g/t gold. Hole AM-09-034 terminated in mineralization.

About the Ajax Project

Abacus is an exploration and development company with a 43-101 compliant positive preliminary economic assessment report (announced June 22, 2009) for its Ajax copper/gold project located 10 kilometres southwest of Kamloops, British Columbia. The report contemplates a 60,000 tonne per day operation producing an average of approximately 110 million pounds of copper and 100,000 ounces of gold in concentrate annually. Sensitivity analyses approximating metal prices (US$2.75 per pound copper and US$1,000 per ounce gold) in the assessment indicate a NPV of $1.2 billion discounted 8% over a 23 year mine life, with an IRR of 31.3%, cash costs of $0.90 per pound copper, and payback of 2.3 years. The Ajax extension remains open along strike and at depth. Mineral resources that are not mineral reserves do not have demonstrated economic viability.

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