Toronto, Ontario--(Newsfile Corp. - April 25, 2022) -
Palladium One Mining Inc.
(
TSXV: PDM)
(OTCQB: NKORF) (FSE: 7N11
) (the "
Company
" or "
Palladium One
") is pleased to announce an
updated Indicated and Inferred Mineral Resource Estimate ("MRE") prepared the Company under the
supervision of SLR Consulting (Canada) Ltd. (formerly Roscoe, Postle Associates Inc.) disclosed in
accordance with National Instrument 43-101 ("NI43-101") for the 100%-owned Läntinen Koillismaa
("LK") Project in north-central Finland (Figure 1).
"We are pleased to report important milestones that measurably de-risk our LK PGE-Cu-Ni Project in
Finland.
Namely, a) a maiden Mineral Resource Estimate at Kaukua South and Murtolampi which
increases the Kaukua Area's indicated resources tonnes by approximately 250%; b) advanced
metallurgical testing conducted by SGS (Lakefield) which demonstrates consistently repeatable
metallurgical recoveries; and c) the ability to produce both a high-value copper and nickel concentrate
using a conventional flotation recovery process.
"These milestones substantially improve the economic potential by confirming scale and by delivering
clarity of recovery rates for various rock types.
"With a grade of 30% copper in the copper concentrate and a value of approximately US$4,200 per
tonne for the nickel concentrate, both are highly marketable, which bodes well for future concentrate
marketing negotiations.
"While continued exploration in 2022 to increase the size of LK is ongoing, we have accelerated
baseline environmental studies and plan to advance a Preliminary Economic Assessment ("PEA").
"The bulk of 2022's exploration efforts are expected to be in Canada and directed to the award winning
Tyko Ni-Cu Project.
Once drill permits are received, we plan to drill test several multi-line VTEM
anomalies where highly anomalous soil sample values of copper nickel and cobalt were discovered in
2021. To date, additional drill permits have not been received," commented Derrick Weyrauch,
President and CEO.
Highlights
In addition to the Mineral Resource Estimate ("MRE") which used US$1,700/oz palladium (Table 1a,
2b), a sensitivity analysis was completed with seven optimized open-pit constrained resource estimates,
with palladium prices ranging from US$900/oz to US$2,500/oz (Table 2a, 2b).

(see Table 1b).
248% increase in Indicated tonnes
and a
14% increase in Inferred tonnes
.
44% of the MRE is in the Indicated category.
A waste to ore ratio
("Strip Ratio")
of
1.48:1 in the Kaukua Area (including Murtolampi) and
a 0.58:1 Strip Ratio at Haukiaho.
The MRE assumes a Net Smelter Return ("NSR") cut-off of US$12.50 per tonne, based on a
20,000 tonne per day milling rate.
Includes three open-pits in the Kaukua Area (including Murtolampi) and one at Haukiaho, 10-
kilometers to the south of Kaukua.
Recovered, and payable metal assumptions are based on the 2022 Phase II Metallurgical Testing
Program, and preliminary indicative copper and nickel smelter quotes.
Future Resource Expansion
LK remains open for additional resource expansion both along strike and at depth.
The MRE covers approximately 5 kilometers of the 38-kilometer marginal series contact
zone, for which reconnaissance historical drilling indicated mineralization along nearly it's
entire length.
The Company's near-term targeting includes two additional open-pit targets in the Kaukua
Area and possibly multiple open-pit targets along the 17-kilometer Haukiaho Trend.
Three areas of Target Potential have been defined for near term resource expansion
representing an additional 2.4-kilometer of strike length along the favourable marginal series
and could add between 21.6 million and 36.0 million tonnes of resource. Refer to Table 3,
Figures 4 & 5.
2022 Phase II Metallurgical Testing Program
The Phase II Metallurgical Testing Program demonstrates the ability to produce
BOTH a high-
value copper AND a high-value nickel concentrate
("Con") utilizing conventional 3-stage
flotation.
The Cons were readily and
consistently reproduced.
Locked Cycle Test results:
Locked Cycle Bulk Concentrate recoveries: 73.5% Pd, 56.1% Pt, 73.0% Au, 88.6% Cu,
30.3% Ni, and 18.6% Co (Table 5).
Copper Concentrate:
Grades of 30.0% Cu,
1.43% Ni, 0.1% Co,
38.3 g/t Pd, 13.1 g/t Pt,
11.2 g/t Au
representing a
value of US$6,300 per tonne of concentrate
(Table 6).
Nickel Concentrate:
Grades
of 4.8% Ni, 3.9% Cu, 0.2% Co,
40.8 g/t Pd, 11.0 g/t Pt, 2.9
g/t Au
representing a
value of US$4,200 per tonne of concentrate.
Rhodium values up to 1.7 g/t and 1.0 g/t were reported in both the Nickel and
Copper Concentrates respectively,
while the MRE does not include rhodium values.
Fortunately, both Cons are high in iron and sulfur and low in MgO, thereby improving
marketability.
A low mass pull of 1.2% was achieved, thereby suggestive of low transportation charges.
Other
In aggregate, there is 38 million tonnes of Indicated and 50 million tonnes of inferred in resources,
thereby providing the opportunity for a large tonnage long-life mine to be developed.
The LK project has excellent infrastructure with paved roads, power, skilled labour and is less than
180 kilometers from the port of Oulu, thereby providing the opportunity for reduced initial capital
cost estimates.

Notes:
1
.
CIM (2014) definitions were followed for Mineral Resources.
2
.
The Mineral Resources have been reported above a preliminary open pit constraining surface using a Net Smelter Return (NSR) pit discard
cut-off of US$12.5/t (which for comparison purposes equates to an approximately 0.65 g/t Palladium Equivalent in-situ cut-off, based on
metal prices only).
3
.
The NSR used for reporting is based on the following:
a
.
Long term metal prices of US$ 1,700/oz Pd, US$ 1,100/oz Pt, US$ 1,800/oz Au, US$ 4.25/lb Cu, US$ 8.50/lb Ni and US$ 25/lb Co.
b
.
Variable metallurgical recoveries for each metal were used at Kaukua and Murtolampi and fixed recoveries of 79.8% Pd, 80.1% Pt,
65% Au, 89% Cu, 64% Ni and 0% Co at Haukiaho.
c
.
Commercial terms for a Cu and Ni concentrate based on indicative quotations from smelters.
4
.
Total Precious Metals (TPM) equals palladium plus platinum plus gold
5
.
Bulk densities range between 1.8 and 3.23 t/m
3
.
6
.
Numbers may not add up due to rounding.
7
.
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.
8
.
The quantity and grade of reported inferred resources in this estimation are conceptual 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.
Palladium Equivalent (PdEq)
Palladium equivalent ("PdEq") is calculated using US$1,700 per ounce for palladium, US$1,100 per
ounce for platinum, US$1,800 per ounce for gold, US$4.25 per pound for copper, US$8.50 per pound
for nickel, and $25 per pound cobalt consistent with the calculation used in the Company's current
Mineral Resource Estimate for the LK project. PdEq was used for wireframe construction and
metallurgical test work only, and does not include metallurgical recoveries or smelter terms, and was not
used for generation of the conceptual pit shells or Mineral Resource reporting. The Mineral Resource
tabulation is based on a unit NSR value which includes metal prices, metallurgical recoveries and
contract terms for Ni and Cu concentrates.
Mineral Resource Estimation Methodology
The Kaukua/Murtolampti drillhole
database comprises 21004 drillholes for a total of 44,139441.45 m
drilling. The Haukiaho drillhole database comprises a further 84 drillholes for a total of 13,392.3 m drilling
. An updated 3D geological model has been constructed using Leapfrog software version (Figure 4).
Kaukua
For Kaukua, Key lithological units modelled include the basement gabbro and granodiorite as well as the
intrusive or Marginal Series pyroxenite, peridotite and gabbronorite units. Major controlling structures
have been used to split the deposit into three zones with subsidiary faults, major stratigraphic units,
diabase dykes and the overburden modelled within these four zones.
Faults outline the Pit, Gap and
South Zones (sub-domains of the Kaukua deposit). A topographic surface has been generated using
Lidar data.
Grade shells have been modelled at 0.3 g/t and 0.6 g/t PdEq thresholds using the vein system modelling
in Leapfrog Geo within the geological constraints as determined.
Capping was completed on assays prior to compositing. A composite length of 6 m has been used, with
the composites within each mineralized domain assessed for the need to apply grade caps. Continuity
analysis (variography) has been completed on the composited samples within the various mineralization
domains with the resultant variograms checked against the mineralization domain to ensure geological
consistency.
A block model has been constructed in Hexagon Minesight software using a 6 m (X) by 6 m (Y) by 6 m
(Z) block size. No sub-celling or rotation of the block model has been undertaken.
The block model has been coded by lithology and mineralization domain for each element.
The later,
cross-cutting diabase dykes and overburden have been coded into the block model with the grades for
Pd, Pt, Cu, Ni, Co and Au set to background values in the block model.
The estimation of grade has been undertaken in two interpolation passes using ordinary kriging, with the
0.6 g/t PdEq mineralization wireframes used as firm-boundaries during the estimation. Dynamic
anisotropy was used to accommodate local changes in dip and strike of the mineralization. Each
subsequent interpolation pass has used an increased search ellipse size and a decrease in the
minimum number of samples required:
Pass 1 estimations have been undertaken using a minimum of three and a maximum of 8
composites into a 120 m x 120 m x 60 m search ellipse, with a maximum of 2 composites per
drillhole,
Pass 2 estimations have been undertaken using a minimum of one and a maximum of 8
composites into a 200 m x 200 m x 60 m search ellipse, with a maximum of one composite per
drillhole,
Final grade estimates for Pd, Pt, Ni, Cu, Co and Au have been validated by statistical analysis and
visual comparison to the input drillhole composite data. The estimated Pd, Pt, Cu, Ni, Co and Au grades
validate within acceptable limits to the input declustered composite grades. Therefore, the block model
accurately reproduces the input grades at a global scale. Swath plots show that there are negligible local
biases. Change of support validation shows that the kriged model grades contain a suitable amount of
internal dilution for the anticipated mining selectivity.
Blocks were classified as Indicated and Inferred in accordance with CIM Definition Standards 2014.
Blocks were classified to the Inferred category if the block fell within 80 m of a composite. Indicated
category blocks were classified using a drill-spacing of 50 x 50 m in the Pit area and 100 x 50 m in the
South area.
Murtolampi
A grade shell has been modelled at a 0.3 g/t PdEq
threshold using the vein system modelling in
Leapfrog Geo within the geological constraints as determined.
Capping was completed on assays prior to compositing. A composite length of 6 m has been used, with
the composites within each mineralized domain assessed for the need to apply grade caps. The
variogram modelled for Kaukua was used at Murtolampti as there are an insufficient number of
composites to model a robust variogram.
A block model has been constructed in Hexagon Mineplan
software using a 6 m (X) by 6 m (Y) by 6 m
(Z) block size. No sub-celling or rotation of the block model has been undertaken.
The block model has been coded by lithology and mineralization domain for each estimation of grade
has been undertaken in two interpolation passes
The estimation of grade has been undertaken in two interpolation passes using ordinary kriging.
Anisotropy directions were selected based on the geometry of the mineralization. Each subsequent
interpolation pass has used an increased search ellipse size and a decrease in the minimum number of
samples required:
Pass 1 estimations have been undertaken using a minimum of three and a maximum of 8
composites into a 120 m x 120 m x 60 m search ellipse, with a maximum of 2 composites per
drillhole,
Pass 2 estimations have been undertaken using a minimum of one and a maximum of 8
composites into a 200 m x 200 m x 60 m search ellipse, with a maximum of one composite per
drillhole,
Final grade estimates for Pd, Pt, Ni, Cu, Co and Au have been validated by statistical analysis and
visual comparison to the input drillhole composite data. The estimated Pd, Pt, Cu, Ni, Co and Au grades
validate within acceptable limits to the input declustered composite grades. Therefore, the block model
accurately reproduces the input grades at a global scale. Swath plots show that there are negligible local
biases.
Haukiaho
Key lithological units modelled include the basement, gabbro/peridotite/pyroxenite and diabase. A fault
divides the mineralization into eastern and western blocks. A topographic surface has been generated
using Lidar data.
A grade shell has been modelled at a 0.25 g/t PdEq thresholds using the vein system modelling in
Leapfrog Geo within the geological constraints as determined.
Capping was completed on assays prior to compositing. Several historic drillholes are missing Au, Pt
and Pd assays. Linear regression (RMA) with high correlation coefficients against Cu and Ni assays has
been used to assign Au, Pt and Pd grades to these drillholes. A composite length of 5 m has been used,
with the composites within each mineralized domain assessed for the need to apply grade caps.
A block model has been constructed in Hexagon Mineplan
software using a 10 m (X) by 10 m (Y) by 10
m (Z) block size. No sub-celling or rotation of the block model has been undertaken.
The block model has been coded by lithology and mineralization domain for each element.
The later,
cross-cutting diabase dykes and overburden have been coded into the block model with the grades for
Pd, Pt, Cu, Ni, Co and Au set to background values in the block model.
The estimation of grade has been undertaken using inverse-distance weighting to the power of three in
two interpolation passes, with the 0.25 g/t Pd-equivalent mineralization wireframes used as a hard-
boundary during the estimation. Dynamic anisotropy was used to accommodate local changes in dip
and strike of the mineralization. Each subsequent interpolation pass has used an increased search
ellipse size and a decrease in the minimum number of samples required:
Pass 1 estimations have been undertaken using a minimum of three and a maximum of 8
composites into a 200 m x 200 m x 50 m search ellipse, with a maximum of 2 composites per
drillhole,
Pass 2 estimations have been undertaken using a minimum of two and a maximum of 8
composites into a 300 m x 300 m x 50 m search ellipse, with a maximum of two composites per
drillhole,
Final grade estimates for Pd, Pt, Ni, Cu, Co and Au have been validated by statistical analysis and
visual comparison to the input drillhole composite data. The estimated Pd, Pt, Cu, Ni, Co and Au grades
validate within acceptable limits to the input declustered composite grades. Therefore, the block model
accurately reproduces the input grades at a global scale. Swath plots show that there are negligible local
biases. Change of support validation shows that the kriged model grades contain a suitable amount of
internal dilution for the anticipated mining selectivity.
Blocks were classified as Inferred in accordance with CIM Definition Standards 2014. Blocks were
classified to the Inferred category if the block fell within 120 m of a composite.

Metallurgical testing (2022 Phase II program) results:
Variability testing for five main lithologies and a Master Composite of similar grade to the Kaukua
resource area was conducted.
Results:
Concentration by conventional floatation produces a saleable bulk concentrate with no
deleterious elements, irrespective of lithology.
A clean, high value saleable Copper Concentrate can be produced.
A clean, high value saleable Nickel-PGE Concentrate can be produced.
A detailed floatation metallurgical program was conducted by the Company on the Kaukua & Kaukua
South deposits. Both deposits posses very similar geology and mineralization, and bulk sample of
approximately 1 metric tonne from 22 holes comprising both Upper and Lower Zone mineralization was
shipped to SGS Lakefield in Canada in summer of 2021. This sample was blended to produce a
representative composite sample of the Lower Zone mineralization with grade of 1.66 g/t PdEq (0.63 g/t
Pd, 0.22 g/t Pt, 0.10 g/t Au, 0.13% Cu, 0.14% Ni, 88 g/t Co) (Table 5). In additional, ten individual
samples (five high and five low grade) consisting of the four dominant rock types that comprise the
Lower zone plus a fifth for the Upper zone were analysed for variability testing.
Results from the current metallurgical program have highlighted very consistently reproducible recovery
rates form the Kaukua/Kaukua South mineralization. Copper and PGE recovery being only slightly
affected by changes in grade, only nickel recovery is significantly affected by grade, as the percentage of
silicate nickel increases as grade decreases.
Historical test work in 2011 on the Kaukua deposit was also performed by SGS Lakefield. This earlier
composite sample had a similar bulk composition to the current metallurgical sample but was higher
grade 2.38 g/t PdEq (0.94 g/t Pd, 0.31 g/t Pt, 0.08 g/t Au, 0.22% Cu, and 0.20% Ni). Results from this
earlier test were consistent with result from the current test and further confirm the consistency of the
floatation recovery.
In addition to a Bulk Con, a split copper and nickel con were produced. Both of which are highly saleable
(Table 6). The Copper Con is particularly high-grade with 30% Cu and high PGEs. The Copper Con
represents 30% by weight of the Bulk Con with the Nickel Con comprising 70%. In addition, the Bulk Con
had a low 1.2% mass pull, and low deleterious elements including <6% MgO in the nickel concentrate.
The LK project is located 160 north east of the Port City of Oulu, thereby significantly decreasing
potential shipping costs. In addition, Finland has domestic copper and nickel smelting capacity further
potentially reducing shipping costs.
