Palladium One High Grade Mineralization Extended 250 Meters Southwest of the Kaukua Open Pit Resource, Finland

• Geological interpretation changed at the Kaukua Deposit.
• High-grade core zone extended to the southwest, 250 meters beyond the current Open Pit Mineral Resource Estimate ("MRE").
• 3.2 g/t Palladium Equivalent (Pd_Eq) over 13.7 meters, within 1.6 g/t Pd_Eq over 113.6 meters, in hole LK21-102, with individual samples grading up to 9.6 g/t Pd_Eq over 1.00 meters.
• 3.3 g/t Pd_Eq over 9.6 meters, within 1.5 g/t over 113.4 meters, in hole LK21-100, with individual samples grading up to 5.9 g/t Pd_Eq over 1.5 meters.
• 2.2 g/t Pd_Eq over 19.6 meters, within 1.5 g/t Pd_Eq over 74.5 meters, in hole LK21-101.

Toronto, November 23, 2021 - Initial down plunge drilling, has extended mineralization 250 meters southwest of the open-pit constrained MRE of the Kaukua Deposit, by intersecting 2.2 g/t Pd_Eq over 19.6 meters, within 1.5 g/t Pd_Eq over 74.5 meters, starting at 273 meters down hole (LK21-101) (Figure 1), said Palladium One Mining Inc. (TSXV: PDM) (FSE: 7N11) (OTCQB: NKORF) ("Palladium One" or the "Company").

Derrick Weyrauch, President and CEO commented: "The high-grade "Core Zone" of the Kaukua Deposit has been extended to the southwest and remains open for expansion. These are among the thickest intercepts to date within the Kaukua Deposit and will add significant tonnage to our existing resource endowment. An updated NI43-101 Mineral Resource Estimate is schedule for Q1 2022 and will incorporate these valuable results."

These drilling results extend the Kaukua Deposit mineralization southwest of the existing conceptual open-pit, where it remains open (Figure 1 and 2). Previous geological interpretations suggested that the Kaukua deposit was cut-off by a northwest trending fault, occupying a distinct magnetic low and topographic lineament. Drilling has now demonstrated that the magnetic low is the result of a later cross cutting dyke (now referred to as the high-titanium gabbro dyke) and that the Kaukua deposit remains open to the south. Significantly the high-grade "Core Zone" of the Kaukua Deposit has been extended 250 meters to the southwest and we have encountered some of the thickest intercepts (>100m) to date within the deposit.

Table 1. LK Project, Kaukua Drill Hole Results

* Pd_Eq calculated using in-situ values and prices from the 2021 NI43-101 Haukiaho Mineral Resource Estimate; $1,600/oz Pd, $1,100/oz Pt, $1,650/oz Au, $3.50 Cu, and $7.50 Ni, and $20/lb Co. Limited historical metallurgical work on the Kaukua Deposit indicates final recoveries in the range of 73% Pd, 56% Pt, 78% Au, 91% Cu, 48% Ni and 0.48% Co and are used in the Estimated Recovered Pd_Eq grade calculation.

Palladium Equivalent
The Company is calculating Palladium equivalent using US$1,600 per ounce for palladium, US$1,100 per ounce for platinum, US$1,650 per ounce for gold, US$3.50 per pound for copper, US$7.50 per pound for nickel, and $20/b cobalt consistent with the calculation used in the Company's September 2021 NI 43-101 Haukiaho Resource Estimate.
