North American Palladium Provides Update on Lac des Iles Exploration Program

TORONTO, April 05, 2018 (GLOBE NEWSWIRE) -- North American Palladium Ltd. ("NAP" or the "Company") (TSX:PDL) (OTC PINK:PALDF) today announced results from its exploration program at its Lac des Iles mine (“LDI”), located 90 km north of Thunder Bay, Ontario.

2018 Offset South Zone Drilling Results

• Hole 18-801 intersected 149 metres averaging 1.8 g/t Pd, including 17 metres averaging 2.9 g/t Pd and 33 metres averaging 3.1 g/t Pd.
• Hole 18-802 intersected 92 metres averaging 1.3 g/t Pd, including 8.0 metres of 3.5 g/t Pd and another 79 metre interval averaging 1.49 g/t Pd with 3.9 metres of 6.0 g/t Pd.
• Hole 18-803 intersected 49 metres averaging 1.43 g/t Pd, including 3.0 metres of 5.0 g/t Pd.
• Hole 18-901 intersected 159 metres averaging 1.5 g/t Pd, including 8.0 metres of 3.5 g/t Pd.
• Hole 18-902 intersected 65 metres averaging1.4 g/t Pd, including 20 metres of 2.0 g/t Pd.
• Previously announced drill results included several holes with higher grade palladium mineralization, for example, hole 17-803 intersected 10.0 metres averaging 6.9 g/t Pd and hole 17-807 intersected 10.0 metres averaging 6.1 g/t Pd.
• The reported intersections also contain Pt, Au, Ni and Cu concentrations that are approximately the same as those currently being mined in the central part of the Offset zone, where byproduct metal sales account for ~20% of total revenue.

“We are excited that the latest results from the Offset South zone, which is located directly adjacent to our primary underground mining operations, confirm the zone has the widths required for mass mining with our well-established, low-cost, sub-level shrinkage method. Infill drilling is now required to determine the average grade within this highly prospective zone. Future resource gains from this and our many other near-mine exploration targets can extend the life of the mine at a very low capital cost,” said Jim Gallagher, President and CEO of North American Palladium.

“The recent drilling results for the Offset South zone confirm its status as the top-ranked opportunity for a significant, near-term resource addition at LDI. In addition, we are pursuing resource gains on several other underground exploration targets, all of which occur in close proximity to current mining activity in the Roby and Offset zones. We are also exploring for new near-surface resources, with this year’s program focusing on two targets in the eastern part of the mine property,” said Dr. Dave Peck, North American Palladium’s Vice-President, Exploration.

Offset South Zone

The southern part of the Offset zone (Figure 1) has been a focus for exploration drilling at LDI since mid-2017. Fifteen holes and 7,762 metres have been completed since the current program began. The results confirm the presence of a large, tabular area of greater than 1 g/t Pd mineralization occurring directly south of the sub-level shrinkage mining area (Figure 2). The Offset South zone typical varies from 50 to 100 metres in true thickness and contains multiple higher-grade sections, including several intersections exceeding 3 g/t Pd over core lengths of up to 41 metres and a smaller number of 2 to 10 metre intervals averaging 5 to 7 g/t Pd. All significant drilling intersections from the 2017 and 2018 Offset South zone drilling program are provided in Table 1.

The recent drilling has confirmed that the southern end of the Offset zone splits into two divergent mineralized trends collectively referred to as the ‘pantleg’ structure. Both trends are composed of palladium-rich magmatic breccia and varitextured norite. They are separated by a sporadically mineralized equigranular norite unit and include the thicker, southwest-trending Offset South zone (the western ‘pantleg’) and a narrower and less well defined, southeast trend (the eastern ‘pantleg’) (Figure 2). The eastern trend includes the modelled down-plunge extension of the B2 zone. Both trends remain open along strike and at depth and represent the highest ranked targets for adding palladium resources at LDI.

Plans for the Remainder of 2018

Future drilling in the Offset South zone will focus on delineating indicated resources (see ‘gap’ target, Figure 3) and establishing the continuity and distribution of higher-grade areas.

Additional 2018 underground exploration drilling targets at LDI include (Figure 3):

• The down-plunge extension of the B2 zone;
• The Offset deep footwall target; and
• The Mystery zone target.

Surface exploration at LDI resumed this month at the Creek zone target, where an outcropping of approximately 200 metres by 150 metres south-plunging target area was recently defined (Figure 4). Additional surface drilling is planned for the Shorty Lake target, which has a similar geometry and size to the Creek zone target, and in the Roby Southwest zone, remains open below and to the southwest of the currently defined mineral resources (Figure 4). Additional drilling on the down-plunge extension of the Sheriff South zone may also occur later in the year.
