TORONTO, ONTARIO--(Marketwired - Dec 23, 2013) - North American Palladium Ltd. ("NAP" or the "Company") (PDL.TO)(NYSE MKT:PAL) today provided an update on its drill results from the second half of its 2013 underground and surface exploration program at its Lac des Iles ("LDI") palladium mine property in Northern Ontario.

Highlights:

• Surface drilling on the upper Roby Zone northeast extension target extended a near-surface part of the zone. Several typical Roby Zone open pit grade intersections of palladium mineralization were encountered, including 2.44 grams per tonne of palladium ("g/t Pd") over 16 metres, 2.13 g/t Pd over 17 metres and 1.79 g/t Pd over 24 metres. The program also encountered some high-grade palladium mineralization, including 16.4 g/t Pd over 3 metres.
  
  

• Several surface drill holes testing the upper Offset Zone southeast extension target intersected significant palladium grades with hole 13-717 returning 5.23 g/t Pd over 37.6 metres, including 8.24 g/t Pd over 10 metres. Hole 13-717's intersection occurs 240 metres from the new shaft and above the Offset Zone mine infrastructure in an otherwise undrilled area. Follow up drilling has been planned for 2014 to define the geometry and extent of this new discovery.
  
  

• Three short drill holes that were following up positive 2013 channel sampling results at the north end of the Sherriff Zone intersected high grade palladium mineralization. One hole hit 10.15 g/t Pd over a 16 metres within which a 4.7 metre interval graded 23.6 g/t Pd. This intersection occurs close to surface (45 to 58 metres vertical depth). This demonstrates additional high-grade mineralization can still be found on the property, away from the well-defined Roby and Offset high-grade zones.
  
  

LDI Exploration Overview

The exploration program's focus during the second half of 2013 was to identify lateral zone extensions near existing infrastructure, northeast of the Roby Zone and southeast of the upper Offset Zone.

In the second half of 2013, the Company completed 23,250 metres of diamond drilling at LDI of which:

• 7,216 metres (38 surface drill holes) were completed on the upper Roby Zone northeast extension target;
  
  

• 15,836 metres (27 surface drill holes) were completed on the upper Offset Zone southeast extension target; and
  
  

• 198 metres (3 surface drill holes) were completed on the north Sheriff Zone target.
  
  

In 2013 the Company completed a total of 54,532 metres of diamond drilling at LDI in 212 drill holes. For reference, the results from drilling during the first half of 2013 were disclosed in a news release dated September 5, 2013, available on NAP's website.

The results from the 2013 program, including the results from the potential lateral extension targets, will be considered in the studies and life of mine update planned for 2014 to establish the potential to extend mine life.

Figure 1 in the Appendix shows the locations of the program's exploration targets during the second half of the year. A tabulation of significant palladium ("Pd"), platinum ("Pt"), gold ("Au"), nickel ("Ni"), and copper ("Cu") assays received from drilling completed in the second half of 2013 are included in Table 1 in the Appendix, with select highlights listed in the tables referred to throughout this news release. All mineralized intersections are given as down hole intervals and core lengths in metres.

Roby Zone Northeast Extension Target

The objective of the upper Roby Zone northeast extension drilling program was to attempt to connect the undeveloped North VT Rim west resource to the northeast end of the Roby Zone open pit, thereby providing a potential future surface mining opportunity for the Company.

Highlights from this program are provided in Table 1 below, which include notable intersections of:

• 2.44 g/t Pd over 16.3 metres (hole 13-218);
  
  

• 2.13 g/t Pd over 17 metres (hole 13-226);
  
  

• 9.20 g/t Pd over 4 metres (hole 13-228);
  
  

• 16.35 g/t Pd over 3 metres (hole 13-236); and
  
  

• 1.79 g/t Pd over 24 metres (hole 13-240).
  
  

The results to date suggest that the Roby Zone does appear to connect to the North VT Rim along southwest trending shears and in association with a southwest striking noritic layer with grades reporting both to structures and to the noritic layer.

Upper Offset Zone Southeast Extension Target

The objective of the upper Offset Zone southeast extension drilling program was to test if the Offset Zone continues upward and toward the southeast along the currently interpreted arcuate strike of the Equigranular Gabbro unit in the same manner that the Roby Zone follows the arcuate Equigranular Gabbro contact towards the North VT Rim.

Highlights from this program are provided in Table 2 below, which include notable intersections of:

• 3.62 g/t Pd over 6 metres (hole 13-704);
  
  

• 4.58 g/t Pd over 8 metres (hole 13-707); and
  
  

• 4.34 g/t Pd over 50 metres (hole 13-717).
  
  

Results from the drilling program indicate that although palladium mineralization is intermittently present along the arcuate-trending target adjacent to the Equigranular Gabbro contact, it generally does not appear to have sufficient continuity to warrant additional infill drilling at this stage. However, the high-grade mineralization encountered in hole 13-717 does warrant follow-up drilling as it could potentially connect to an isolated new zone of good grade palladium mineralization located to the south of and above the main Offset Zone resource shell. The controls on the distribution of palladium in this new target area are currently unresolved but may relate to a northwest-trending fault or shear zone located to the south of the Offset Zone fault.

North Sheriff Zone Surface Exploration

In late September, three short drill holes were completed at the north end of the Sheriff Zone in order to determine the continuity along strike and to depth of previously identified surface mineralization (historical and recent channel sampling results).

Highlights from this program are provided in Table 3 below, which include notable intersections of:

• 10.15 g/t Pd over 16 metres (hole 13-118); and
  
  

• 2.06 g/t Pd over 12 metres (hole 13-119).

True widths have not been determined yet; there is no relationship between the reported interval lengths, average grades and the true width. Additional drilling and surface mapping will be required to establish the strike and dip of the mineralization encountered in the North Sheriff Zone area.

Mineral Reserve and Resource Update

A comprehensive update to LDI's mineral reserve and resource estimates is expected to be provided in January 2014. The Company is currently working with an external engineering firm to revisit its Phase I mine plan for the upper Offset Zone based on recent refinements to the underground mining method, operating costs and capital expenditure forecasts. The results of this work will be provided in a National Instrument 43-101 ("NI 43-101") technical report that will be published in the first quarter of 2014.
