Palladium One Expands High-Grade at Kaukua

South, Drills 47 Meters @ 2.6 g/t Pd_Eq,

Including 12 Meters @ 4.2 g/t Pd_Eq

Toronto, Ontario--(Newsfile Corp. - March 18, 2021) - Drilling has returned significant PGE (Platinum

Group Element) grades of

47 meters at 2.6 g/t Pd_Eq

, including

12 meters at 4.2 g/t Pd_Eq

. (Hole

LK21-045), defining a high-grade core at Kaukua South on the Läntinen Koillismaa ("LK") PGE-Ni-Cu

project in Finland, said Palladium One Mining Inc. (TSXV: PDM) (FSE: 7N11) (OTCQB: NKORF)

("Palladium One" or the "Company") today.

Thus far, 34 holes have been drilled as part of the 17,500-meter Phase II Resource Definition drill

program at Kaukua South, including today's results 22 have been released, while results for 12 holes are

pending.

Drilling has been strategically undertaken to define mineralization from surface to a depth of

200 metres, leaving mineralization open at depth, across the known 4-kilometer strike length of Kaukua

South.

In total 6,404-meters have been drilled to date as part of the Phase II program at Kaukua South,

while an additional 860-meters (6 holes) of regional exploration has been undertaken.

Derrick Weyrauch, President and CEO of Palladium One said, "Drilling at Kaukua South continues to

intersect impressive grades and widths, thereby proving up the known four-kilometer strike length of

Kaukua South. Induced Polarization (IP) surveys have been started to expand the Kaukua South strike

length by up to three kilometers. With robust drill results thus far and the potential to increase the Kaukua

South strike length to

seven kilometers

we are optimistic that, in addition to our existing Kaukua

National Instrument 43-101 pit constrained resource, a new multi-million ounce resource is well within our

reach."

"In addition to our Phase II Kaukua South drill program and to take advantage of winter drilling

conditions, 2,000 meters (12 holes) were recently drilled on the Haukiaho zone. This drilling represents

completion of the infill campaign that was launched in February 2020 and suspended in March 2020 due

to Covid-19.

The drill program was designed to provide additional data in advance of a NI 43-101

resource estimate.

Assay results are pending," said Weyrauch.

Highlights

Drilling continues to demonstrate continuity of near surface open pit grades and widths

at Kaukua South.

Core zone of

11.6 meters grading 4.21 g/t Palladium equivalent

("Pd_Eq") within

47.4 meters

grading 2.59 g/t Pd_Eq.

in hole LK21-045, starting 123 meters down hole.

Core zone of

16.5 meters grading 2.52 g/t Pd_Eq,

within

52.7 meters grading 1.53 g/t Pd_Eq

in hole LK21-046, starting 66 meters down hole.

2,000 meters of drilling completed on the Haukiaho Zone to upgrade the historic resource to

National Instrument 43-101 standards.

Kaukua South Infill Drilling

Kaukua South infill drilling continues to demonstrate consistent near surface open pit grades and widths.

A total of 22 holes from the Phase II infill drill program on Kaukua South have now been released with

intersections such as

53 meters at 2.1 g/t Pd_Eq,

in hole LK20-028 (see press release

January 18,

2021

) and

33 metres grading 2.0 g/t Pd_Eq

in hole LK20-034 (see news release

March 11, 2021

).

These 22 holes cover approximately 1.3 kilometers of the Kaukua South Zone and have returned similar

widths and grades to those in the Kaukua NI 43-101 Open Pit resource estimate. (Figure 1 and 2).

IP Survey Underway

Induced Polarization ("IP") surveys have proven to be highly successful at outlining palladium-rich

disseminated copper-nickel sulphide mineralization on the LK Project. The discovery of Kaukua South in

an overburden covered area with no previous drilling was a direct result of the Company's 2020 IP

survey.

The current IP survey is well advanced, with the western grid anticipated to be completed within the next

week. The Company believes there is potential to extend the currently Kaukua South IP chargeability

anomaly from the currently defined four to over seven kilometres of strike length (Figure 1).

Haukiaho Drill Program

The Haukiaho Zone is located 15 kilometers to the South of Kaukua. In late February and early March

2021, the Company completed 2,000 meters (12 holes) of infill drilling to enable the historic Haukiaho

resource to be upgraded to NI 43-101 compliant standards. The Haukiaho Zone which hosts the historic

Haukiaho deposit, is part of a 17-kilometre-long trend (Figure 4.), and prior to the discovery of the

Kaukua South Zone had a top priority for the Company and it remains a significant asset of the greater

LK project.

In March 2020, before being forced to shut down due to the first wave of the Covid-19 pandemic, the

Company completed 3 holes on the Haukiaho Zone returning a core zone of

34.2 metres grading 2.09

g/t Pd_Eq. within 83.3 metres grading 1.27 g/t Pd_Eq

. in hole LK20-010 (see news release

September 15, 2020

).

In February 2020, the Company completed an IP survey covering five-kilometres of the Haukiaho Trend

(see news release

May 7, 2020

). This survey identified three strong chargeability anomalies, one of

which is associated with the core of the historic Haukiaho deposit, however the other two are in areas of

sparse historic drilling. The eastern most of these three anomalies was

prospected by the Company

in 2019, returning up to

3.3 g/t Pd_Eq.

(0.51% Cu, 0.33% Ni, 0.56 g/t Pd, 0.18 g/t Pt, and 0.21 g/t

Au), (see news release

August 12, 2019

).

Historic Haukiaho Resource Estimates

In 2013, Finore Mining Inc. completed a non-pit constrained NI 43-101 historic resource with a 0.1 g/t Pd

cut-off at Haukiaho comprising 23.2 million tonnes grading 1.51 g/t Pd_Eq (0.31 g/t Pd, 0.12g/t Pt, 0.10

g/t Au, 0.21% Cu, and 0.14% Ni) (See news release

August 12, 2019

and

May 7, 2020

).

This resource

encompassed widely spaced drilling with a focus on maximizing tonnage, not grade. An earlier historic

resource estimate completed by Outokumpu in the 1980's covered a much larger part of the Haukiaho

trend and was focused more on grade and used a 0.7% Cu_eq cut-off (defined as Cu% + 2 x Ni%) and

returned 7 million tonnes grading 0.38% Cu and 0.24% Ni, however importantly, no PGE assays were

conducted.

* Reported widths are "drilled widths" not true widths.

** Orange shaded values previously released (see press release

January 18, 2021

.

*Palladium Equivalent

Palladium equivalent is calculated using US$1,100 per ounce for palladium, US$950 per ounce for

platinum, US$1,300 per ounce for gold, US$6,614 per tonne for copper, and US$15,4332 per tonne for

nickel. This calculation is consistent with the calculation in the Company's September 2019 NI 43-101

Kaukua resource estimate.

QA/QC

The Phase I drilling program was carried out under the supervision of Neil Pettigrew, M.Sc., P. Geo.,

Vice President of Exploration and a director of the Company.

Drill core samples were split using a rock saw by Company staff, with half retained in the core box and

stored indoors in a secure facility, in Taivalkoski, Finland. The drill core samples were transported by

courier from the Company's core handling facility in Taivalkoski, Finland, to ALS Global ("ALS")

laboratory in Outokumpu, Finland. ALS, is an accredited lab and are ISO compliant (ISO 9001:2008,

ISO/IEC 17025:2005). PGE analysis was performed using a 30 grams fire assay with an ICP-MS or

ICP-AES finish. Multi-element analyses, including copper and nickel were analysed by four acid

digestion using 0.25 grams with an ICP-AES finish.

Certified standards, blanks and crushed duplicates are placed in the sample stream at a rate of one

QA/QC sample per 10 core samples. Results are analyzed for acceptance at the time of import. All

standards associated with the results in this press release were determined to be acceptable within the

defined limits of the standard used.
