Abacus Intersects 318 Metres (1043.3 Feet) Of 0.43% Copper And 0.26 g/t Gold At Ajax

VANCOUVER, BC April 28, 2008 Abacus Mining & Exploration Corp. ("Abacus" or "the Company") (TSX.V:AME) is pleased to announce additional assay results for the Ajax East and West pit drill program.  The focus of that drilling (62 holes drilled in 2007) was to continue delineating copper-gold mineralization beneath the Ajax West and East pits on the Abacus-owned Crown-granted claims. The information from this drilling will be incorporated into the combined Ajax 43 -- 101 resource estimation planned for completion in June 2008, which will also include drill results from the joint venture area between the pits.  

"We are pleased to see assay results that fit with our overall model for the planned development of the Ajax area", said Doug Fulcher, President and CEO.  "Management continues to meet the goals that have been set for 2008 for the ongoing development of the Ajax area.  We have now completed the first phase of drilling on the joint venture ground between Ajax West and Ajax East, with results to be announced shortly."

  • Hole AW-07-072 intersected 318 metres (1043.3 feet) grading 0.43% copper and 0.26 g/t gold, including a 75 metre (246.1 feet) intercept averaging 0.67% copper and 0.45 g/t gold and a 99 metre (324.8 feet) intercept averaging 0.61% copper and 0.27 g/t gold.

About the Afton Area

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. The Company has completed about 480,000 feet (146,304 metres) of drilling and 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 cut-off).

The Ajax property comprises of eight 100% owned Crown grants which include the historic Ajax East and West pits.  Also included is an interest in claims between the pits acquired from a joint-venture agreement signed with New Gold 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.  With the completion of the high priority drilling in the joint venture ground, the project is now down to two drill rigs turning on the property. These two drills will continue to carry out definition drilling throughout the Ajax area in order to maximize the assignment of resources into measured and indicated categories.

The updated DM zone resource will be completed within the next few weeks and the greater Ajax area will have a compliant resource estimate scheduled for completion by the end of June.  Upon completion of the resource estimates, Abacus intends to progress the Afton project through preliminary economic studies and into feasibility during the second half of 2008 and completed in early 2009.  The Company's goal is to develop, large-scale surface mining operations at Afton producing between 40,000 and 60,000 tonnes per day by 2010.

Eco Tech Laboratory Ltd. of Kamloops, B.C., has completed all of Abacus' 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.
