May 11, 2021 – Toronto, Ontario – Drilling continues to intersect impressive widths and grades of Platinum Group Elements (“PGE”) including 38 meters at 2.1 g/t Palladium equivalent (“Pd_Eq”) (Hole LK21-062) in the Lower Zone at Kaukua South, on the Läntinen Koillismaa (“LK”) PGE-Ni-Cu project in Finland, said Palladium One Mining Inc. (“Palladium One” or the “Company”) (TSXV: PDM, FRA: 7N11, OTC: NKORF) today. Drilling has also expanded the strike length of the Upper Zone having intersected robust mineralization which returned 51 meters @ 0.9 g/t Pd_Eq (Hole LK21-064).
46 holes (9,469 metres) have been drilled as part of the 17,500-meter Phase II Resource Definition drill program at Kaukua South, including today’s results 34 have been released, while results for 12 holes await assays. Additionally, assay results are pending for 12 drill holes at the Haukiaho Zone, where the Company completed infill drilling in advance of a NI43-101 resource estimate. Drilling is currently in hiatus for the spring thaw and is schedule to resume in later May.
When drilling resumes the intent is to target open pit resource definition of the Lower mineralized zone (down to 300 meters) on the western side of Kaukua South, and to extend mineralization immediately south of the existing Kaukua NI43-101 Open Pit constrained resource estimate.
“Our understanding of an Upper Zone of mineralization continues to expand and so does our realization that it could add a significant amount of resources to the planned NI43-101 resource estimate.
The Upper Zone lies in the hanging wall of the high-grade Lower Zone which has been the primary focus of the Phase II drill program.
The Upper Zone’s position could have a significant positive economic influence on the any future open pit scenario; and as evidenced by hole LK21-064 it can locally carry substantial grades.” said Derrick Weyrauch, President and CEO.
- Results to date are highly encouraging and show a clear path toward a maiden open pit resource at Kaukua South.
- Drilling demonstrates significant continuity of open pit grades and widths in both the Upper and Lower Zones at Kaukua South.
- 2.06 g/t Pd_Eq over 37.9 meters in hole LK21-062 (Lower Zone)
- 1.22 g/t Pd_Eq over 70.5 meters in hole LK21-064 (Lower Zone)
- 0.92 g/t Pd_Eq over 50.6 meters in hole LK21-064 (Upper Zone)
- Drilling in Kaukua south has consistently returned grades and widths, over 2 kilometers of strike length, similar to those in the Kaukua NI43-101 Open Pit constrained resource estimated immediately to the northwest.
Kaukua South Infill Drilling
Kaukua South infill drilling continues to demonstrate consistent open pit grades and widths. A total of 34 holes from the Phase II infill drill program on Kaukua South have now been released with intersections such as 47 meters at 2.6 g.t Pd_Eq in hole LK21-045 (see press release March 18, 2021) and 53 meters at 2.1 g/t Pd_Eq*, in hole LK20-028 (see press release January 18, 2021).
Kaukua South Upper Mineralized Zone
Kaukua South consists of two subparallel mineralized zones, the very continuous Lower Zone near the base of the Intrusion, which is very similar to the Kaukua deposit with high PGE tenors, has been the main focus of the current drill program. The Upper Zone occurs in the hanging wall of the Lower Zone and is characterised by higher Cu-Ni values and lower PGEs (Table 1). The Upper Zone is typically more sporadic than the Lower Zone but can exhibit great widths such as seen in hole LK21-064 which returned 50.6 meters grading 0.92 g/t Pd-Eq (Figure 2). It’s position in the hanging wall relative to the Lower Zone is key and has significant positive implications for the open pit potential of Kaukua South as it could reduce the strip ratio and allow the pit to extend to greater depths than originally contemplated and thereby improve project economics. As such, the Company is planning to define the Lower Zone down to a 300-meters depth in areas with strong Upper Zone mineralization (Figure 1.).

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. Additionally, US$1,100 per ounce for palladium is consistent with the UBS January 2021 long-term consensus price forecast even though the current price of palladium is approximately US$3,000 per ounce.
