North American Palladium Intersects High Grades Underground at LDI Mine and Reef-Style Mineralization on Surface Near Open Pit

30.01.2012  |  Marketwire

TORONTO, ONTARIO -- (Marketwire) -- 01/30/12 -- North American Palladium Ltd. ('NAP' or the 'Company') (TSX: PDL)(NYSE Amex: PAL) today provided an update on the remaining drill results from its 2011 exploration program at the Company's Lac des Iles ('LDI') palladium mine in Northern Ontario. These results (see Appendix) are the third and final tranche of drill results from the 2011 program.


Highlights:



-- Infill drill results in the Offset Zone returned excellent grades, with
good width and continuity, including 78 metres at 7.39 grams per tonne
Palladium ('g/t Pd') and 33 metres at 8.71 g/t Pd;
-- Good indication of a southern extension to the Offset Zone in an area
previously reported as the Southern Norite Zone, including 39 metres at
4.02 g/t Pd and 15 metres at 5.13 g/t Pd;
-- Mineralization discovered 300 metres to the west of the Offset, Cowboy
and Outlaw zones, including 10 metres of 3.05 g/t Pd, giving support to
the interpretation that some mineralized zones manifest as a series of
parallel stacked lenses;
-- Confirmed north and south lateral extensions of upper Roby Zone,
including 18 metres at 12.82 g/t Pd; and
-- Bonanza grade surface mineralization encountered from trenches along the
North VT Rim 500 metres northeast of the LDI open pit, including
approximately 1 metre samples at 64.4 g/t Pd and 45.8 g/t Pd.


'The success of our 85,000-metre drill campaign in 2011 underpins the significant exploration potential of the LDI property, and supports our view that we have only scratched the surface in our exploration endeavours,' stated William J. Biggar, President and Chief Executive Officer. In addition to confirming excellent grades in the Offset Zone over significant intercepts, the 2011 exploration program continues to expand the size of the Offset Zone and parallel mineralized zones; provides new targets for Roby Zone mining adjacent to existing underground infrastructure; and gives a new surface target with exceptional grades.'


Mr. Biggar added: 'As we pursue our organic growth strategy through the LDI mine expansion, exploration will continue to be a key focus for the Company for many years to come. As an established PGM producer with excess mill capacity on a permitted property, we are well positioned to convert exploration success into production and cash flow on an accelerated timeline.'


The objectives of NAP's 2011 exploration program were to expand the Offset Zone, improve knowledge of the Offset Zone mineralization through infill drilling, and identify potential surface targets (see Figures 1, 2 and 3 for an overview of drill locations). In 2011, 261 holes totaling 84,686 metres were drilled on the LDI property. Underground drilling accounted for 41,343 metres (205 holes), of which approximately 13,290 metres (66 holes) were to support mine operations. Drilling from surface accounted for the remaining 43,343 metres (56 holes). Previous exploration updates on the 2011 program were issued by news release on June 28, 2011 and September 14, 2011.


The visual images and complete drill results are included in an Appendix to this news release posted on the Company's website. It is estimated that true widths represent on average 70% of the reported lengths for surface drilling and on average 80% of the reported lengths for underground drilling.


Offset Zone Delivers Excellent Grades and Continues to Expand


Infill drilling on the Offset Zone continued throughout 2011 to define the upper and middle portions of the ore body on a 15-metre drill pattern in preparation for production (see Figures 4 and 5). The holes were drilled on a fan pattern from the Offset Zone ramp and the vast majority intersected the Offset Zone, returning good widths and grades, the majority which are higher than the current resource estimate. Although the Cowboy Zone was not specifically targeted, it was frequently intersected during the drill campaign.


The 800-series holes of the infill drilling targeted the middle portion of the Offset Zone, which continued to intersect high grade intervals. Some of the best results from the 800-series holes include:



----------------------------------------------------------------------------
Length of Grade
Hole From To Intersection (g/t Pd) Location
----------------------------------------------------------------------------
11-829 100 m 178 m 78 m 7.39 Offset & Cowboy
----------------------------------------------------------------------------
11-801 104 m 137 m 33 m 8.71 Offset
----------------------------------------------------------------------------
11-817 91 m 124 m 33 m 8.60 Offset
----------------------------------------------------------------------------
11-804 103 m 114 m 11 m 18.06 Offset
----------------------------------------------------------------------------
11-831 116 m 125 m 9 m 20.07 Offset
----------------------------------------------------------------------------


The 700-series of holes targeted the southern portion of the Offset Zone, at the outer portion of the current resource model (see Figures 6 and 7). Results continue to show high grades and good continuity as well as high grade footwall mineralization that may be associated with the Cowboy or Outlaw zones. Significant mineralization was encountered in the Cowboy Zone, including 11 metres at 7.22 g/t Pd (Hole 11-710) and 24 metres at 5.5 g/t Pd (Hole 11-717).


Notable drill results from the 700-series holes include:



----------------------------------------------------------------------------
Length of Grade
Hole From To Intersection (g/t Pd) Location
----------------------------------------------------------------------------
11-748 125 m 151 m 26 m 5.17 Offset
----------------------------------------------------------------------------
11-719 209 m 237 m 28 m 4.75 Offset
----------------------------------------------------------------------------
11-717 22 m 46 m 24 m 5.5 Cowboy
----------------------------------------------------------------------------
11-718 203 m 221 m 18 m 5.63 Offset
----------------------------------------------------------------------------
11-722 108 m 121 m 13 m 5.01 Offset
----------------------------------------------------------------------------
11-710 24 m 35 m 11 m 7.22 Cowboy
----------------------------------------------------------------------------
11-825 40 m 47 m 7 m 4.28 Cowboy
----------------------------------------------------------------------------
11-829 60 m 66 m 6 m 7.44 Cowboy
----------------------------------------------------------------------------
11-711 28 m 33 m 5 m 9.84 Cowboy
----------------------------------------------------------------------------
11-749 147 m 151 m 4 m 16.04 Offset
----------------------------------------------------------------------------


Moreover, there is good indication of a southern extension to the Offset Zone in an area previously reported as the Southern Norite Zone (see the Appendix for the drill results for Southern Norite Zone and Figures 10 and 11 for the location of the drill holes).


Notable results from these drill holes include:



----------------------------------------------------------------------------
Length of Grade
Hole From To Intersection (g/t Pd) Location
----------------------------------------------------------------------------
11-027 206 m 245 m 39 m 4.02 Norite
----------------------------------------------------------------------------
11-023 944 m 959 m 15 m 5.13 Norite
----------------------------------------------------------------------------


The Company is investigating whether the Southern Norite Zone is an extension of the Offset Zone towards the south.


The 900-series of holes targeted an area to the west of the Offset Zone from an underground platform. These results discovered more footwall mineralization to the west of the mineralized Outlaw Zone (see Figures 8 and 9). This is the Company's first attempt to drill beyond the Cowboy and Outlaw zones, which were discovered to the west of the Offset Zone in 2009. Additional work will be required to understand how the 300 metres of previously unknown mineralized gabbros relates to the three currently identified zones. The results do, however, give support to the interpretation that mineralization adjacent to the Offset Zone consists of a series of parallel stacked lenses.


Roby Zone Expands Laterally


The Roby Zone drill campaign was designed to confirm north and south extensions of the mineralization in the upper part of the mine. Definition drilling in 2011 followed palladium mineralization previously encountered and results continue to confirm northern and southern extensions (Figures 12 and 13).


Some notable drill results include:



----------------------------------------------------------------------------
Length of Grade
Hole From To Intersection (g/t Pd) Location
----------------------------------------------------------------------------
11-214 215 m 233 m 18 m 9.27 Roby North
----------------------------------------------------------------------------
11-217 238 m 256 m 18 m 12.82 Roby North
----------------------------------------------------------------------------
11-234 55 m 71 m 16 m 9.03 Roby South
----------------------------------------------------------------------------


The Company is developing a mine plan for both upper Roby Zone extensions. Development has already commenced towards the new North Block, which will allow further drilling to expand the resource northward. In the southern extension, development is still at the planning stage.


Bonanza Grade Mineralization Encountered at North VT Rim


The Company discovered bonanza grade Platinum Group Elements (PGEs) at surface in trenches along the North VT Rim approximately 500 metres northeast of the LDI open pit, including 0.98 metre at 64.4 g/t Pd and 0.8 metre at 45.8 g/t Pd (see Figures 14 and 15). Corresponding platinum values for these intervals are 5.2 g/t Pt and 2.46 g/t Pt, which are broadly in line with palladium to platinum rations in the nearby Roby and Offset zones.


The North VT Rim target was known to have anomalous palladium values that follow the contact with the East Gabbro and Varied-Textured Gabbro (VT-Gab) to the east but such high grades had not previously been encountered. The geological controls on the high grade palladium mineralization along the North VT Rim target are still being investigated. Available technical data indicate that the mineralization is generally stratabound and stratiform in nature and features very low sulfide content that is generally not visible in hand specimens. The mineralization along this contact may be similar to other PGE 'reef-style' occurrences found in the Bushveld and Stillwater complex.


The most noteworthy grades from trenching on the North VT Rim include:



----------------------------------------------------------------------------
Length of Pd. Grade Pt. Grade Au. Grade
Trench ID Intersection (g/t) (g/t) (g/t)
----------------------------------------------------------------------------
TR11-04-011 0.98 m 64.4 5.17 1.19
----------------------------------------------------------------------------
TR11-04-103 0.80 m 45.8 2.48 1.59
----------------------------------------------------------------------------
TR11-04-102 1 m 37.3 2.44 0.33
----------------------------------------------------------------------------
TR11-04-027 1 m 23 0.98 0.58
----------------------------------------------------------------------------
TR11-04-026 0.9 m 22.3 0.99 0.33
----------------------------------------------------------------------------


While very encouraging, additional work is required on the North VT Rim to understand the nature of the mineralization. The Company intends to follow up on these results during 2012 with a drill campaign targeted below the highest grade trench mineralization with larger diameter HQ drill core.


2012 LDI Exploration


NAP will continue to invest in exploration to expand the reserves and resources at LDI and to identify new targets. In total, NAP plans to drill approximately 70,000 metres in 2012, of which 64,000 metres will be at LDI, and 6,000 metres at NAP's other nearby properties. Approximately 55,000 of the 64,000 metres to be drilled at LDI is in connection with the LDI mine expansion.


The primary focus of the exploration program will be underground exploration at LDI targeting the Offset Zone, to conduct infill drilling as well as to test extensions of the Offset Zone mineralization towards surface, at depth, and to the south. In addition, drilling will be conducted at North LDI, the North VT Rim and at Legris Lake.
