Palladium One Reports Final Assay Results for Kaukua South Drilling, Finland, Returned 4.4 g/t Pd_Eq over 7.5 Meters within 2.6 g/t Pd_Eq over 49.3 Meters

Highlights

• All assay results have been received for the greater Kaukua area, three Murtolampi Zone drill holes remain pending.
• Final Kaukua South results include 4.4 g/t Palladium Equivalent (Pd_Eq) over 7.5 meters within 2.6 g/t Pd_Eq over 49.3 meters in hole LK21-122.
• The Far Eastern IP Anomaly was tested with two holes both returning Upper and Lower Zone Kaukua-style PGE-Cu-Ni mineralization, up to 1.5 g/t Pd_Eq over 18.2 Meters in hole LK21-031.
• The Far Eastern IP Anomaly is a high priority area for future resource expansion, and permitting in this area has been accelerated.

Toronto, Ontario--(Newsfile Corp. - February 7, 2022) - Final assay results for Kaukua South are have been received, with intersection up to 4.4 g/t Pd_Eq over 7.5 meters, within 2.6 g/t Pd_Eq over 49.3 meters, in hole LK21-122 starting at 55 meters down hole (Figure 1), said Palladium One Mining Inc. (TSXV: PDM) (OTCQB: NKORF) (FSE: 7N11) ("Palladium One" or the "Company").

Derrick Weyrauch, President and CEO commented: "Resource definition drilling on Kaukua South has again produced stellar grades and widths. New mineralized zones continue to be discovered, as demonstrated with reconnaissance drilling on the Far East IP anomaly which returned Kaukua-style PGE-Cu-Ni mineralization having typical resource grades and widths. It is apparent that the Far East is the highest priority area for resource expansion in the greater Kaukua area, which hosts an approximately 6-kilometer long mineralized strike length."

All assay for the greater Kaukua area, with the exception of three holes in the satellite Murtolampi Zone, have now been received (Figure 1, 2, 3). Resource modelling can now begin for the updated Kaukua mineral resource estimate, expected in Q1 2022.

The Far East IP anomaly (Figure 3) was tested with two drill holes which retuned up to 1.5 g/t Pd_Eq over 18.2 Meters in hole LK21-031 in the Lower Zone. Both holes also intersected the Upper Zone, confirming the same stratigraphy found in Kaukua South. The Upper Zone was also well mineralized returning 1.0 g/t Pd_Eq over 12.0 meters in hole LK21-131. It is now apparent that the Far East IP anomaly is simply a continuation of Kaukua South, which has now been drill tested over 4.5 kilometers and represents an excellent target for additional near surface resource expansion.

Drill pad location options for the Far East IP anomaly (holes LK21-130 & 131) were restricted due to the area's tenure being an Exploration Permit application. Resource definition drilling of the Far East IP anomaly will require receipt of the Exploration Permit as the remaining target area is federally owned land and federal lands can only be drilled with an Exploration Permit.

Drill pad location options are even more restricted for the Western IP bullseye anomaly (Figure 1) and therefore it was only tested with one drill hole, LK21-129. This 401-meter hole was drilled in a suboptimal western direction due to the need to locate the drill pad on an existing Exploration Permit. The hole intersected primarily granophyric intermediate to felsic rock interpreted to be related to thermally altered felsic and intermediate volcanics which form the cap rock of the mafic-ultramafic Kollisamaa Complex. Portion of the granophyric rock contained abundant fine-grained magnetite which may be responsible for the strong chargeability IP response. The rock types intersected in hole LK21-129 suggest that this is the "roof" of the Kollisamaa Complex, indicating that there may be downfaulting along the northeast trending fault to the west of the Kaukua Pit area. Additional testing is planned for this anomaly with more optimal northern drilling directions.

Figure 1. Historic and current drilling in the Kaukua area having a drill data cut-off date of September 30, 2021 (hole LK21-137), assays have been received for holes up to LK21-134, the remainder are pending. Background is Induced Polarization ("IP") Chargeability.
