* CuEq=((% Cu)(Cu recovery)(22.0462)(2.5)+(g/t gold) (gold recovery)(1/31.1035)(750))/((Cu recovery)(22.0462)(2.5))
Cu recovery=43.619 x (% Cu)+63.002, max value = 92% Au recovery = 33.871 x (g/t gold) + 75.29, max value = 90%
Copper equivalent cutoff grades and pit shells were established using metal prices of $2.50 US per pound copper and $750 US per ounce gold.

Doug Fulcher, president of Abacus, said "We are extremely pleased with the results of the resource estimate for the Ajax Deposit. This resource demonstrates the large size of Ajax with approximately 2.5 billion pounds of copper and 2.3 million ounces of gold in a measured and indicated category. Abacus now plans to complete a preliminary economic assessment ("PEA") that contemplates a 60,000 tonne per day operation. The Ajax deposit remains open along strike and at depth. In addition, initial drilling was carried out at the end of 2008 on the northern Monte Carlo area, where there is an offset extension of the Ajax deposit which has the potential to expand the Ajax resource. Results from this drilling will be released when received."

The resource estimate is based on 621 exploration drill holes totalling over 160,000 metres completed in the Ajax West, Ajax East area and the New Gold joint venture ground in between. Approximately 20 percent of the resource is located within the ground covered by the joint venture. As previously announced, interests in the joint venture down to 500 metres below surface are 60% Abacus and 40% New Gold. AMEC created a block model from the drill data and generated conceptual pit shell envelopes using the Lerchs-Grossmann algorithm. The resource was summarized within the pit shells. The mining and milling costs were those deemed reasonable for a conceptual 60,000 tonnes per day project. Metallurgical recovery equations were based on a series of lock-cycle recovery tests performed by G&T Labs of Kamloops BC.

Abacus now plans to complete a PEA that contemplates a 60,000 tonnes per day operation, followed by feasibility studies. The resource coupled with the infrastructure purchased from Teck Cominco Ltd. in 2005 will allow Abacus to continue to move forward quickly in the Afton camp. The infrastructure purchased from Teck Cominco includes a tailings impoundment, water rights, mill and shop buildings, rights of way and surface rights.

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 Abacus' represented qualified person.
