North American Palladium Updates Gold Mineral Reserves and Resources at Vezza Project and Sleeping Giant Mine

April, 27, 2011

TORONTO, ONTARIO -- (MARKET WIRE) -- 04/27/11 -- North American Palladium Ltd. ("NAP" or the "Company") (TSX: PDL)(NYSE Amex: PAL) today released an updated mineral reserve and mineral resource estimate for its Vezza gold project and Sleeping Giant gold mine, located in the Abitibi gold district in Quebec.


--  Vezza's measured and indicated resource increased by 12% to 321,000
    contained ounces. Inferred resources total 102,000 ounces.

--  Remainder of 2010 drill hole assays from Vezza confirm continuity and
    grade, including the best result of 8.6 metres grading 14.6 g/t Au in
    hole V-10-210.

--  Vezza dewatering completed and permitting for bulk sampling well

--  2010 drilling at the Sleeping Giant mine increased the contained ounces
    in the measured and indicated category giving a higher level of
    confidence in the mineral resource.

"We are pleased to see the Vezza gold project advance in accordance with the budget and timeline, as this supports our strategy to organically grow our gold division," said William J. Biggar , President and CEO. "Future growth will come from the continued exploration and development of our advanced gold projects in the Abitibi region, where we have a significant land position and an underutilized mill."

"The updated resource estimate at Vezza shows a growing resource," said Michel Bouchard , Vice President, Exploration and Development. "We have completed the dewatering of the underground levels, and are well advanced on the rehabilitation of the underground infrastructure and services to start underground drilling in the coming weeks. The exploration program is progressing according to our plans, and will enable us to make a production decision on the project at the end of this year."

"At Sleeping Giant, the increase in the measured and indicated resource tonnages supports our decision to intensify drilling in the mine in 2011, giving us greater confidence in the ore zones," added Mr. Bouchard. "There is also upside potential at depth - where we will be developing three new mining levels this year."

Vezza Gold Project Resource, Exploration & Development Update

Vezza is an advanced-stage gold exploration project that is currently being progressed through surface and underground exploration and development towards a production decision, expected by year-end. The plan is to have Vezza ore processed at the nearby Sleeping Giant mill which is 85 kilometres away and accessible by provincial highway.

Vezza Resource Update

In the last few months of 2010, following the acquisition of the project, NAP completed 57 drill holes from surface for a total of 12,105 metres. Results from only the first 27 holes, which were published earlier this year (see news release dated February 14, 2011 at www.nap.com), formed the basis for the updated resource estimate as of December 31, 2010. The updated resource estimate was prepared by Roscoe Postle Associates Inc. ("RPA"), in accordance with National Instrument 43-101 - Standards of Disclosure for Mineral Projects ("NI 43-101").

The update shows a substantial increase in the indicated category of over 200,000 tonnes. The measured and indicated resources' total contained ounces increased by 12% to 321,000 ounces. Roughly 121,000 tonnes were converted from the inferred category to the indicated category.

Vezza Exploration Update

Since the end of 2010, the remaining assay results from the 57-hole drill campaign have been received. Assay results from the remaining 30 holes are not included in the updated resource estimate. True widths are estimated to be about 80% of core length.

This drill campaign confirmed continuity and grade near the surface of the Vezza deposit. Hole V-10-210 showed numerous small flakes of visible gold over the length of the intersection.

In 2011, the Company intends to complete an additional 30,000 metres of drilling to test the continuity and grade of the deposit. Most of the campaign will comprise underground infill drilling, and approximately 5,000 metres of extensional drilling from surface on the west part of the main zone.

Vezza Development Update

The Company has completed the dewatering of the shaft (741 metres from surface) and the four existing underground drifts. Underground rehabilitation of the drifts, stations and underground services (power, pumping and compressed air) is nearly complete. A 5,000-metre surface drilling program has started and two underground diamond drills are mobilized on site.

A bulk sample of up to 40,000 tonnes is also scheduled for the end of the third quarter of 2011. The Company has approval from the Ministry of Natural Resources and Wildlife for the bulk sample and is completing the permitting process with the Ministry of Sustainable Development, Environment and Parks.

In 2011, NAP will invest $26 million in underground exploration and development activities at Vezza, which should put the Company in a position to make a production decision by year-end. Assuming a positive production decision is made, gold production could begin in the first quarter of 2012 at an expected rate of 39,000 ounces per year over a nine-year mine life.

Sleeping Giant Gold Mine Reserves and Resources

The primary objective of the 2010 exploration drilling program at Sleeping Giant was to define and extend the gold zones within the current mine (including infill drilling to achieve greater certainty of the mine's grades) and at depth on the proposed three new mining levels, as well as to increase the level of confidence in mineral resources. During 2010, 194 drill holes were completed at Sleeping Giant, totaling 38,000 metres. Systematic drilling from underground stations has improved the Company's understanding of several previously-known zones and extended them to greater depth.

The table below sets forth estimated mineral reserves and resources as at December 31, 2010 for the Sleeping Giant mine as calculated in accordance with NI 43-101.

(1)  The mineral reserve and mineral resource estimate for the Sleeping
     Giant mine was prepared by Mr. Vincent Jourdain, P.Eng., Ph.D, Donald
     Trudel, P.Geo. and Marc-Andre Lavergne P.Eng., qualified persons under
     NI 43-101.
(2)  Mineral resources are exclusive of mineral reserves.
(3)  Mineral Resources are estimated at varying cut-off grades depending on
     the type of mining method contemplated.
(4)  This updated mineral resource estimate assumes a long-term gold price
     of US $1,100.
(5)  CIM definitions were followed for Mineral Resources. See Cautionary
     Note to U.S. Investors Concerning Estimates of Measured, Indicated and
     Inferred Resources.

Compared to the 2009 reserves and resources, the 2010 drilling program nearly tripled the measured and indicated resource tonnage, while at the same time conserving roughly the same reserves at the end of the year following a year of production. Contained ounces were slightly lower in the reserves category while they more than doubled in the measured and indicated resource categories. Tighter drilling conducted during the year reduced the overall grades but increased the confidence level of the estimation, whereas the overall gold content remained roughly the same year over year. More contained ounces were in higher categories at the end of 2010.

In 2011, the Company intends to conduct 30,000 metres of extensional drilling at a cost of approximately $2.1 million with the objective of extending the mine life further by identifying new resources and converting mineral resources to mineral reserves. A series of deep holes are also planned for 2011 to test the gold zones' extensions up to 300 meters under the three new deeper levels of the mine to plan future development at Sleeping Giant. Results are expected in the fourth quarter of 2011.
