North American Palladium Preliminary Economic Assessment Confirms Long Term Potential of Offset High Grade Zone

Highlights - Production at Lac des Iles mine from the Offset High Grade Zone sustainable at 250,000 ounces palladium per year (plus by-products) to 2018. - Strong financial returns at two-year trailing average prices. Internal Rate of Return (IRR) of 29% before taxes and royalties. - North American Palladium moving immediately to feasibility study.

TORONTO, ONTARIO--(Marketwire - May 7, 2008) - North American Palladium Ltd. (TSX:PDL) (TSX:PDL.WT) (AMEX:PAL) (AMEX:PAL.WS) today announced positive results from a preliminary economic assessment of its Offset High Grade Zone (OHGZ), at the Company's Lac des Iles Mine (LDI) north of Thunder Bay, Ontario. The study indicates the viability of extending the Company's underground mining operation to 2018.

Micon International Limited was engaged to examine the economic viability of several mining scenarios for the OHGZ. These included a continuation of the existing ramp system from the current underground mine, several shaft options and a conveying option. The study concludes that the deposit can be mined at a rate of 4,000 to 7,000 tonnes per day using a series of conveyors and access ramps at an initial capital cost of Cdn$37 million. The base case scenario yielded an internal rate of return of 29% before taxes and royalties, a net present value of US$31.8 million at a 10% discount rate, and a three-year payback period. The report is subject to confirmation by a definitive feasibility study including further delineation of the resources presently classified as inferred.

The Micon study proposes continuation of the longhole stoping mining method currently in use at the existing underground operation at LDI. The development scenario contemplates commencing production from the upper portion of the OHGZ by late 2010, which coincides with the resource depletion in the existing underground operation. Production from OHGZ will ramp up to 6,000 tpd by 2012. Using the conveying system to bring ore to surface is advantageous since it provides a great deal of flexibility in decision-making and with the economics of the project. It avoids the large upfront cost of a conventional shaft-hoist system and spreads the majority of capital expenditures throughout the life of the mine.

Mr. Jim Excell, President and CEO said: "The result from this preliminary economic assessment demonstrates that we could have another decade of underground mining at Lac des Iles. An advantage of this project is that we expect to fund development from 2011 onward from the positive cash flow the project will generate. In light of current favourable PGM market conditions, management is also assessing the economic viability of a southern extension of the open pit, which could prolong the mine life of the open pit by an additional two to three years."

Financial Analysis & Assumptions

Traditional Discounted Cash Flow (DCF) models were prepared to determine the Internal Rates of Return (IRR) and the Net Present Values (NPV) for different metal price assumptions on a pre-tax and pre-royalty basis. The results are summarized as follows:

- Production from the OHGZ ramps up to 6,000 tpd by 2012.

- A 6,000 tpd operation yields 250,000 oz palladium, 16,000 oz platinum, 17,000 oz gold, two million lbs nickel and 4 million lbs copper annually.

- Operating costs are estimated at Cdn$39.75 per tonne.

- Initial capital expenditure of Cdn$37 million; Cdn$188 million remaining capital expenditure funded out of cash flow for the remaining eight years of mine life.

The preliminary economic assessment was prepared under the supervision of Mr. Mani Verma, P.Eng, of Micon International Limited, who is an Independent Qualified Person as defined under NI 43-101, and based on North American Palladium's most recent NI 43-101 report for the OHGZ completed by Scott Wilson Roscoe Postle Associates Inc. (RPA) dated February 23, 2007.

This economic assessment is preliminary in nature and includes measured, indicated and inferred mineral resources. Approximately 80% of the resources included in the preliminary economic assessment are in the inferred category. Inferred mineral resources are considered too speculative geologically to have economic considerations applied to them that would enable the resource to be categorized as mineral reserves. The study's level of accuracy is deemed to be plus or minus 20-25%. There is no certainty that the preliminary economic assessment will be realized.

About The Offset High Grade Zone

The primary deposit at the Company's Lac des Iles property is the Roby Zone, which is currently being mined using open pit and underground mining methods. The OHGZ is believed to be the fault displaced continuation of the Roby Zone mineralization and is located below and approximately 250 meters to the west of the Lac des Iles underground mine. A mineral resource estimate showed that the OHGZ has significantly more mineral resources than the current underground mine at similar grades, while still being open along strike to the north, south and at depth.

The current mineral resource estimates for the OHGZ are as follows:(1)

that are not mineral reserves do not have demonstrated economic
viability.


RPA has been retained to update this mineral resource estimate for the upper portion of the OHGZ using the results of a recent infill drilling program (see press release dated April 29, 2008).

OHGZ Future Development

North American Palladium will immediately proceed to the feasibility stage for this project, including updating the current resource estimate. The Company will be making a development decision by the end of 2008, with production planned to commence in 2010. Ongoing drill programs will be conducted throughout 2009 and 2010 to confirm resources. Potential also exists to add new resources along strike to the north and south and at depth.
