About Abacus
Abacus Mining is an exploration and mine development company focused on the development of the Ajax copper-gold project located 10 kms southwest of Kamloops, B.C. through the KGHM Ajax Joint Venture with KGHM Polska Miedz SA. The project has a positive preliminary economic assessment report (June 22, 2009) that 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.
