Abacus Mining Drills 207 M Of 0.32% Cu At Ajax

Mr. Doug Fulcher reports

ABACUS MINING & EXPLORATION CORP.: PROGRESS REPORT ON DRILLING AT AJAX WEST AND EAST; DRILLING UNDERWAY AT DM-AUDRA-CRESCENT

Abacus Mining & Exploration Corp. has received further results from the diamond drill program on the Ajax property near Kamloops, B.C. The property comprises eight, 100-per-cent-owned Crown grants near Kamloops, B.C., which encompass most of the historical east and west pits that were last mined in 1997 by Afton Operating Company. The Ajax property is situated eight kilometres southeast of the former Afton mill/shop/warehouse infrastructure which the company purchased from Teck-Cominco and is accessible via an existing haul road.

Two diamond drill rigs are currently in operation on the Ajax property. The first drill rig is dedicated to defining a 43-101-compliant resource in the Ajax East zone. The second drill rig is currently being used to fill in and possibly expand the NI-43-101-compliant Ajax West inferred resource estimate completed last March by Beacon Hill Consultants Ltd. (147 million tonnes at 0.36 per cent copper and 0.23 gram per tonne gold at a 0.20 per cent copper cut-off grade).

Two exploratory holes were also drilled into the adjacent Monte Carlo claim from the east side of the Ajax east pit.

A third drill rig is operating at the DM-Audra-Crescent zone which is situated one to 2.5 kilometres east of the Afton mill/shop/warehouse infrastructure. On this property Abacus has already defined a 43-101-compliant resource estimate by Giroux Consultants Ltd. of 28.5 million tonnes indicated at 0.30 per cent copper and 0.15 g/t gold plus 15.8 million tonnes inferred at 0.28 per cent copper and 0.12 g/t gold; both at 0.20 per cent copper cut-off grade. The current drilling is intended to expand on the resource, which is open at depth and along strike. Results will be released when sufficient assay data have been received.

Douglas Fulcher, president of Abacus, states, "This year's drilling program is continuing to expand on the potential size of both the Ajax and DM-Audra deposits." A resource on the Ajax East deposit is expected to be completed this fall and preliminary economics on the whole Ajax area as well as the DM zones is now well under way and expected to be completed in early 2008. The company is currently contemplating to have a full feasibility study completed by the end of 2008. To date, Abacus has drilled over 100,000 metres in the Afton camp with an additional 30,000 metres to be completed this year. Baseline and environmental studies are well under way and will continue throughout the year.

Detailed drilling of the Ajax east pit on Abacus ground is nearing completion. Some infill drilling is still required between the company's southern boundary and Section 1350N, and near the company's eastern claim boundary. Additionally, one or two more longitudinal holes will be completed along a northeast-to-southwest direction to look for clues that will help it determine the orientation that future drilling should take as it moves eastward into the Monte Carlo property.

Monte Carlo property

The Monte Carlo claim is part of a contiguous group of six Abacus-owned Crown-granted claims that cover part of the Ajax east pit deposit and surrounding area, most recently mined by Afton Operating Company. The Monte Carlo claim lies immediately east of the old pit where near-surface historical work indicates the presence of copper-gold mineralization that appears to be similar to, and therefore possibly an eastern extension of, the Ajax zones. Abacus recently completed two exploratory holes into the claim from Section 1450N on the east side of the Ajax east pit and the results demonstrate the presence of copper-gold mineralization, which has the potential to extend to depths encountered at both Ajax open pits. Highlights are shown in the table of Monte Carlo drill results.

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, PGeo, is the qualified person responsible for the design and conduct of the work performed.
