North American Palladium Files Prefeasibility Study on LDI's Initial Offset Zone Reserves
1.1 Million Contained Palladium Ounces Converted into Reserves
TORONTO, ONTARIO -- (Marketwire) -- 02/19/13 -- All figures are in Canadian dollars except where noted.
North American Palladium Ltd. ("NAP" or the "Company") (TSX: PDL)(NYSE MKT: PAL) is pleased to announce that it has filed on SEDAR a National Instrument 43-101 ("NI 43-101") technical report for the LDI property, which includes an initial mineral reserve estimate and Prefeasibility Study for Phase I of the Offset Zone (the "Prefeasibility Study").
Summary:
-- Initial Offset Zone reserves total 7.7 million tonnes, representing
approximately 1.1 million contained palladium ounces.
-- Management estimates that at current metal prices (US$750 palladium
price), the economic analysis shows $226 million in undiscounted post-
tax cash flow (determined as net revenue less operating and capital
costs) for the initial Offset Zone reserves, a 95% internal rate of
return ("IRR") (over a 27-month payback period), and a net present value
("NPV") of $187 million at a 5% discount rate.
-- The Prefeasibility Study economic analysis was only applied to the
converted reserves (representing approximately one third of the entire
Offset Zone deposit in the measured and indicated category), however
much of the infrastructure spend associated with those reserves is
expected to also be utilized for the additional mining phases in the
future.
-- $79 million capital investment in 2013 to complete Phase I of the LDI
mine expansion, which is expected to allow the Company to transition
operations to shaft production in the third quarter of 2013, which is
expected to allow the Company to increase underground mining at a
reduced cash cost per ounce.
-- There is significant upside potential from continued exploration at the
LDI property, where a number of surface and underground targets have
been identified near existing infrastructure, highlighting the potential
for future resource expansion at LDI.
Offset Zone Reserves & Resources
The Offset Zone mineral reserve and resource estimate was prepared by independent Qualified Persons of Tetra Tech, Inc. ("Tetra Tech"). Based on the current and future operating plans at the mine, and updated metal price assumptions that are consistent with current consensus price forecasts, the Company has reduced its palladium cutoff grade from 3.5 grams per tonne ("g/t") to 2.5 g/t to calculate the reserves and resources.
Proven and probable reserves are estimated to be 7.7 million tonnes at a grade of 4.30 g/t of palladium, representing 1.1 million ounces of contained palladium. For the purpose of the Prefeasibility Study, the new reserves are based on the Phase I portion of the measured and indicated resources of the Offset Zone above the 990-metre mine level, which qualified due to density of drilling (see Figure #1 below).
The following table provides the Offset Zone mineral reserve estimate using a 2.5 g/t Pd cutoff:

----------------------------------------------------------------------------
Pages 14-31 through 14-37 of the Prefeasibility Study include tables and graphs using various cutoff grades to demonstrate the robust nature of the resources. The Company plans to provide its next annual reserve and resource update in the third quarter of 2013 using the 2.5 g/t cutoff grade for all underground resource models.
For comparative purposes, the following Offset Zone mineral resource estimate (which formed the basis for the conversion of the reserves) also uses a 2.5 g/t cutoff:

Notes:
1. Prepared in accordance with National Instrument 43-101 - Standards of
Disclosure for Mineral Projects (NI 43-101) and the Canadian Institute
of Mining, Metallurgy and Petroleum classification system. U.S.
investors should refer to the Annual Information Form for an overview on
how Canadian standards differ significantly from U.S. requirements.
2. Palladium ounces are stated as contained ounces. Disclosure of contained
ounces is permitted under Canadian regulations; however, the SEC
generally permits resources to be reported only as in place tonnage and
grade. Numbers may not add due to rounding.
3. Mineral reserves for the Offset Zone were estimated by Todd McCracken,
P.Geo., William Richard McBride, P. Eng., Todd Kanhai, P. Eng., and
Phillip Bridson, P.Eng. of Tetra Tech, independent Qualified Persons
within the meaning of NI 43-101. The mineral reserves were estimated
from drilling completed to March 31, 2012.
4. Reserves were estimated to the 990 Mine Level (4490 m elevation), a
maximum depth of 1017.5 metres.
5. The following metal price assumptions were used for reserves estimation:
US$675/oz palladium, US$1,675/oz platinum, US$1,750/oz gold, US$8.00/lb
nickel, and US$3.50/lb copper. A US$/Cdn$ exchange rate of US$1.00 =
CDN$1.00 was also applied. An average production rate of 3500 tonnes per
day was used to determine the reserves.
6. The following mill recoveries were used in the assumptions to determine
the reserves: 80.45% palladium, 71.30% platinum, 83.97% gold, 43.13%
nickel and 88.55% copper.
7. Mineral resources for the Offset Zone were estimated by Todd McCracken,
P.Geo., of Tetra Tech, an independent Qualified Person within the
meaning of NI 43-101. The mineral resources were estimated from drilling
completed to March 31, 2012. The mineral resource calculation uses a
minimum 2.5 g/t Pd resource block cut-off. The mineral resource estimate
is based on the combination of geological modeling, geostatistics and
conventional block modeling (5 m x 5 m x 5 m blocks). Assay grade
capping was determined not to be necessary. The Offset Zone resource
models used the ordinary kriging (OK) grade interpolation method within
a three-dimensional block model with mineralized zones defined by
wireframed solids. The QA/QC protocols and corresponding sample
preparation and shipment procedures for the Offset Zone have been
reviewed by Tetra Tech. Resources were estimated to the 4070 Mine Level
(-930 m elevation), a maximum depth of 1,430 m. The following metal
price assumptions were used: US$675/oz palladium, US$1,675/oz platinum,
US$1,750/oz gold, US$8.00/lb nickel, and US$3.50/lb copper. A US$/Cdn$
exchange rate of US$1.00 = CDN$1.00 was also applied.
8. Mineral resources which are not mineral reserves do not have
demonstrated economic viability. The estimate of mineral resources may
be materially affected by environmental, permitting, legal, title,
taxation, sociopolitical, marketing, or other relevant issues. The
quantity and grade of reported inferred resources in this estimation are
uncertain in nature and there has been insufficient exploration to
define these Inferred resources as an Indicated or Measured mineral
resource and it is uncertain if further exploration will result in
upgrading them to an Indicated or Measured mineral resource category.
The 7.7 million tonnes of Offset Zone reserves grading above 2.5 g/t palladium represent only approximately one third of the 22.1 million tonnes of the overall measured and indicated resources grading above 2.5 g/t. Using the same 2.5 g/t cutoff, there are approximately 14 million additional tonnes of identified Offset Zone inferred resources, therefore the Prefeasibility Study takes a conservative view of the Offset Zone relative to the total resource wireframe. The Company has a clear resource replacement strategy and remains confident that it can continue to expand its reserves and resources through exploration. See Figure #1 below for a visual of the Offset Zone reserves contemplated in the Prefeasibility Study, relative to the other known resources.

The remaining resources require further definition before they can be converted into reserves. Development plans and stoping schedules have been applied to total mineral reserves in anticipation of upgrading the remaining known resources. Accordingly, the Company intends to study the extension of development and shaft sinking adjacent to the lower portion of the Offset Zone and conduct further definition and extension drilling of the Offset Zone.
Economic Analysis
The economic analysis in the Prefeasibility Study uses a conservative palladium price assumption however management estimates that at current prices, the economics show additional upside.
----------------------------------------------------------------------------
Current Prices Study Prices
(US$750 Pd) (US$675 Pd)
----------------------------------------------------------------------------
Post-Tax Cash Flow (Offset Zone reserves only) $226 M $171 M
IRR 95% 64%
Payback Period 27 months 32 months
NPV (at a 5% discount rate) $187 M $138 M
----------------------------------------------------------------------------
Notes:
1. Metal price assumptions used for the "current prices" economic analysis:
US$750 Pd US$1,700 Pt, US$1,650 Au, US$3.70 Cu and US$8.20 Ni.
2. Metal price assumptions used in the Prefeasibility Study: US$675 Pd,
US$1,675 Pt, US$1,750 Au, US$3.50 Cu and US$8.00 Ni.
Capital Expenditures to Extract Offset Zone Reserves
The Prefeasibility Study also highlights a $79-million investment in 2013 to complete Phase I of the LDI mine expansion (as detailed in the Prefeasibility Study), which will transition operations to shaft production in the third quarter of 2013, allowing the Company to increase underground mining at a reduced cash cost per ounce. This investment is based only on the new Offset Zone reserves, and includes sinking the shaft to the 825-metre level, and advancing underground development in the Offset Zone (including extending the ramp at depth, completing the new mine levels and setting up mining stopes), as well as mine-expansion related sustaining capex.
Exploration Upside Potential
The Company believes there remains significant upside potential from continued exploration at the LDI property, where a number of surface and underground targets have been identified for follow up exploration. The Offset Zone remains open to the west, south and at depth, and management is confident that further drilling has a high probability of finding more resources close to the new underground infrastructure.
The Company's recent exploration program returned excellent drilling results (see January 31, 2013 news release) that showed potential to extend the Offset Zone and identified new potential sources of near-surface, pit-grade ore, highlighting the potential for future resource expansion at LDI. Work has already commenced to assess the production potential of the Sheriff Zone and the 2013 exploration efforts will be focused on defining extensions to both the Offset and Roby zone resources, as well as identifying additional pit-grade material at surface.
Other important information to note when reading the technical report:
-- As noted above, the Prefeasibility Study takes a conservative view of
the entire Offset Zone deposit, focusing exclusively on just the Offset
Zone reserves, as required for a prefeasibility level study. The capital
spend discussed in the economic analysis of the technical report is only
for the initial reserves, however much of the infrastructure capital
associated with exploiting those reserves is expected to also be
utilized for accessing additional mining phases in the future.
-- The production profile contained in the Prefeasibility Study for the
initial Offset Zone reserves extends to 2018 based on the assumed mining
rate, however the Company anticipates that the mine life will be
extended well beyond 2018 through further exploration success
discovering additional resources and converting known resources into
reserves.
-- The Prefeasibility Study presents a production profile based upon a
single production platform through Phase I development, with the shaft
operating on average at 3,500 tonnes per day. Should additional
resources be converted into reserves, a second production platform could
be established, allowing the Company to potentially increase its
underground mining rate to 5,500 tonnes per day.
-- The Prefeasibility Study shows mine expansion-related capital
expenditures for the Offset Zone reserves under $25 million in 2014,
however it should be noted that future development capital will need to
be updated to reflect additional reserves and continued expansion at
depth, which will require more development.
-- Other discussions in the technical report, as it pertains to the mine
expansion, are based on the measured and indicated resources of the
Offset Zone, detailing the mine design, mining methods, and production
scenarios. These assumptions remain predominately unchanged from the
Company's current approach and previously disclosed plans (see October
5, 2011 news release). The mine design at this stage includes all
development and construction required to access the diluted mineable
reserve for mining by a bulk mining method and to transport the mined
ore via shaft to the existing milling facilities on site.
