North American Palladium Provides LDI Exploration Update

TORONTO, ONTARIO, Jun 07, 2010– North American Palladium Ltd. (“NAP” or “the Company”) today provided an update on the drill results from its 2010 exploration program at the Company’s flagship Lac des Iles (“LDI”) palladium mine in Northern Ontario. These results (see table in appendix) are the first tranche of drill results from a 53,000 metre 2010 drill program underway at LDI.

— Current mine (Roby Zone) extended approximately 100 metres north and at depth
— Offset Zone extended higher towards surface
— Continued positive drill results throughout the Offset Zone

“The positive drill results from our 2010 exploration program to date confirm our belief that there remains considerable exploration upside at LDI. These results support our organic growth strategy, suggesting that we will be able to extend mining in the Roby Zone beyond two years, and that the Offset Zone will provide at least an additional 10 years of mining at an annualized production rate in the range of 250,000 ounces per year”, said William J. Biggar, President and CEO. “With permits, mine infrastructure and mill facilities already in place, we are confident that we can move from exploration success to production on an accelerated timeline,” added Mr. Biggar.

None of the results reported today are incorporated in the resource update for the Offset Zone released on May 27, 2010, which only included results from the 2009 program.

Since the beginning of 2010, four drills have completed 63 holes totaling 20,500 meters, of which:
— 26 holes (5,485 meters) were completed from underground on the extension
of the Roby Zone; and
— 37 holes (15,015 metres) were completed on the Offset Zone including:
(i.) underground on the upward extension of the Offset Zone (mine
elevation 4900 and higher – “Upper Offset Zone”);
(ii.) on the Central Offset Zone to complete the previous drilling
pattern and to follow its northern extension; and
(iii.) from surface with directional drilling, with the first deep holes
into the Lower Offset Zone (mine elevation 4650 and lower).

Drill results are included in the appendix of this news release. Elevations referred to in this news release are presented in the mine grid in Figure 1, available online at

Roby Extension
The 2010 underground drill campaign extended the Roby Zone approximately 100 metres north and at depth. The mineralized area encountered are located immediately adjacent to the underground infrastructure that is currently utilized for production from the Roby Zone, which is presently mined at a rate of 2,600 tonnes per day (140,000 oz palladium per annum).

Some of the most encouraging drill results include:
— Hole 10-102: where an average value of 5.0 g/t Pd was intersected over
18 metres;
— Hole 10-105: where a 6 metre intersection graded 24.3 g/t Pd, including
1 metre at 109.0 g/t Pd (one of the best intercepts in LDI’s history);
— Hole 10-114: which intersected 11 metres grading 5.3 g/t Pd, including 6
metres at a grade of 8.0 g/t Pd;
— Hole 10-118: which intersected 5 metres at a grade of 13.4 g/t Pd;
— Hole 10-119: which intersected 11 metres grading 6.9 g/t Pd; and
— Hole 10-121: which intersected 18 metres grading 6.7 g/t Pd.

The positions of the holes are shown in Figure 2, available online at

An additional 10 holes are planned for 2010 to follow the Roby Zone at depth and north. The Company is also currently evaluating the impact of these results on the mine plan, which is expected to lengthen production from the Roby Zone from its current forecast of 140,000 ounces per year for 2 years.

Offset Zone
Since the beginning of 2010, three different parts of the Offset Zone were drilled:
— The Upper Offset Zone, which is the upper extension over mine elevation
— The Central Offset Zone, (mine elevation between 4650 and 4900) which
was the subject of the 2009 drill campaign; and
— The Lower Offset Zone, under mine elevation 4650.

The Upper Offset Zone:
The 2010 underground drilling has extended the Upper Offset Zone approximately 50 metres higher on the 4950 elevation, where drilling encountered some of the best results to date. This mineralized area was not included in the May 2010 resource estimate. Five holes (10-330 to 10-334) were drilled at elevation 4900 on 15 metre spacing and the reported lengths are very close to true widths. Some of the most encouraging drill results include:
— Hole 10-330: which intersected 11 metres grading 10.7 g/t Pd, including
6 metres grading 15.2 g/t Pd;
— Hole 10-334: which intersected 11 metres grading 8.0 g/t Pd, including 5
metres at a grade of 13.1g/t Pd;

Another series of 5 holes (10-301 to 10-305) were also drilled from the Roby underground mine infrastructure towards the 4950 elevation. The Offset Zone was intersected and is still open towards the surface. Some of the best results include:
— Hole 10-302: which intersected 18 metres at a grade of 9.5 g/t Pd,
including 5 metres at a grade of 14.3 g/t Pd; and
— Hole 10-304: which intersected 11 metres of 7.5 g/t Pd, including 6
metres at a grade of 9.3 g/t Pd.

Further drilling will continue to follow the upward extension of the Upper Offset Zone.

The positions of the holes are shown in Figures 2 and 3, available online at

The Central Offset Zone:
In late 2009 and early 2010, two attempts were made to drill from the underground Roby Zone infrastructure to follow the northern extension of the Offset Zone. Due to the unfavorable positioning of the drill bays in space relative to the target, several of the attempted holes missed. However, two holes from the series 09-954 to 09-960 (see appendix) had very favourable intercepts:
— Hole 09-954: intersected 15 metres grading 9.0 g/t Pd, including 5
metres grading 18.6 g/t Pd; and
— Hole 09-955: intersected 16 metres grading 8.2 g/t Pd, including 7
metres at 13 g/t Pd.

Although both holes were drilled at the end of 2009, assay results and interpretation were not available in time for the May resource estimate.

The 10-401 to 10-405 series of drill holes also attempted to follow the north extension of the Offset Zone but they had limited success. Due to the low angle of the intersection, Company geologists estimate the true widths of mineralization to be 50% of those intersections. These results nonetheless support the belief that there is a northern extension of the Offset Zone.

In addition, five holes (10-201 to 10-205) were drilled from underground to infill areas of the Offset Zone where the drill pattern was not regular. All of these intersected the Offset Zone, most over large widths.

Some of the best results are:
— Hole 10-201: which intersected 40 metres at a grade of 6.9 g/t Pd,
including 10 metres at 11.7 g/t Pd;
— Hole 10-204: which intersected 69 metres at a grade of 5.1 g/t Pd,
including 9 metres at 8.0 g/t Pd and 10 metres at 11.5 g/t Pd; and
— Hole 10-205: which intersected 33 metres of 6.2 g/t Pd.

The Lower Offset Zone:
While awaiting the partial completion of a new ramp into the Offset Zone, which will allow for further infill drilling, the Company commenced a surface directional drilling campaign in March 2010 with two surface drills. The objective was to drill deep holes around the 4450-4650 elevation of the Offset Zone.

The first completed hole (10-501) at elevation 4650, in the south part of the Offset Zone, initially intersected an unknown 8-metre mineralized interval commencing at 701 metres down hole, grading 9.6 g/t Pd. It then intersected the Offset Zone at 1,138 metres, for 19 metres grading 3.5 g/t Pd. A second directional hole is in progress and the same unknown mineralized area was again intersected at 703 metres. This second intersection is 5 metres long and returned a grade of 8.4 g/t Pd. A historical review of previous surface holes in the vicinity is in progress to evaluate these findings.

The second surface drill completed hole 10-551, aimed at elevation 4500, in the north part of the Offset Zone. The Offset Zone was intersected at a down hole depth of 1,286 metres, over a length of 28 metres grading an average of 6.0 g/t Pd, including 7 metres from 1,290 to 1,297 metres at a grade of 12.3 g/t Pd. It also intersected a second zone, from 1,369 to 1,387 meters, (a core length of 18 metres) grading 5.5 g/t Pd. The results indicate the potential at depth of the Offset Zone.

Ongoing Exploration
NAP is continuing its significant $15 million 2010 exploration program at LDI. The program consists of 53,000 metres of drilling to expand the size of the Offset and Roby zones, increase the grade of Offset Zone mineralization and to explore the West Pit and other surface areas.
