Abacus Mining Announces Independent Recommendation in Favour of the Joint Venture with KGHM

VANCOUVER, BRITISH COLUMBIA -- (Marketwire) -- 06/10/10 -- Abacus Mining & Exploration Corporation ('Abacus' or the 'Company') (TSX VENTURE: AME) announces that the RiskMetrics Group, a leading provider of risk management and corporate governance products and services, has recommended that Abacus shareholders vote in favour of the Joint Venture with KGHM Polska Miedz S.A. ('KGHM') at the upcoming Special Meeting of Shareholders to be held on June 22, 2010. The analyses and recommendations of the RiskMetrics Group are relied upon by major institutional investors, investment firms and mutual fund managers throughout North America.

In making its recommendation in favour of the Joint Venture with KGHM, the RiskMetrics Group cited numerous reasons in their report released on June 6, 2010(i). 'Based on a review of the terms of the transaction, that the JV partner would provide all the required funding and the fresh investment available to the company, shareholder approval is warranted.'

Other factors mentioned in their report were the fact that KGHM is stated to be Europe's second largest copper producer and, as such, the JV may have longer term strategic benefits, as well as there being no superior proposals at this stage.

(i) Permission to quote from the RiskMetrics report was neither sought nor obtained.

About Abacus

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 (approx. 50,000 tonnes) and 100,000 ounces of gold in concentrate annually. Sensitivity analyses approximating metal prices (US$3.00 per pound copper and US$1,000 per ounce gold) in the assessment indicate a NPV of $1.46 billion discounted 8% over a 23 year mine life, with an IRR of 35.4%, cash costs of $0.90 per pound copper, and payback of 2.0 years. The Ajax extension remains open along strike and at depth. Mineral resources that are not mineral reserves do not have demonstrated economic viability.
