Toronto, Ontario–(Newsfile Corp. – June 23, 2021) – Final results containing massive magmatic sulphide intercepts grading up to 10.2% Nickel equivalent (“Ni_Eq”) (224 lbs/tonne), (23.7% Copper equivalent) over 1.7 meters, within 7.4% Ni_Eq (164 lbs/tonne) (17.4% Copper equivalent) over 4.5 meters, have been received from the Phase II Tyko drill program, located at the at Smoke Lake target of the Tyko NI-Cu Project, said Palladium One Mining (TSXV: PDM) (FSE: 7N11) (OTCQB: NKORF) (“Palladium One” or the “Company”) today.

These results are in addition to last weeks announcement of 9.5% Ni_Eq (210 lbs/tonne), (22.3% Copper equivalent) over 1.7 meters, within 6.0% Ni_Eq (131 lbs/tonne), (13.9% Copper equivalent) over 5.0 meters. (see press release June 17, 2021).

The Phase II program was designed to test the down dip continuity of the EM Maxwell Plates “Plates” that were modelled subsequent to the Q4 2020 Phase I drill program.

A total of 14 holes were completed, 11 of which intersected massive and/or semi-massive sulphide mineralization at the Smoke Lake Zone, which also returned up to 9.9% Nickel equivalent (218lbs/tonne), (23% Copper equivalent, 30.1 g/t Gold equivalent*) (8.1% Ni, 2.9% Cu, 0.61g/t Pd, 0.71g/t Pt, and 0.02g/t Au) over 3.8 metres (see press release January 19, 2021).

President and CEO, Derrick Weyrauch, commented, “Smoke Lake continues to deliver some of the highest sulphide nickel grades globally. We remain focused on finding the source of the remobilized massive sulphide mineralization, which could be located in the large magnetic anomaly immediately below Smoke Lake. Field crews have been mobilized and the summer exploration field season has started. We are cautiously optimistic that there could be additional Smoke Lake-type high-grade nickel zones on the 200km² Tyko Property.”

The most important result of Phase II drill program was the strike length extension to 350-meters combined with linking high-grade massive sulphide mineralization between the ‘upper conductor’ with the ‘lower conductor’ (see hole TK21-034 which returned 6.0% Ni_Eq over 5.0 meters (Figure 1 and 2).

The Phase II drill program indicates a continuous elongate lens of high-grade sulphide mineralization that dips to the west and plunge to northwest. Significantly, the sulphide mineralization appears to be remobilized and injected into the tonalite host rocks, cross cutting the foliation in the tonalite and containing well-rounded tonalite and biotite altered hornblendite clasts.

A total of 14 holes totalling 1,370 meters were completed before a significant drill breakdown combined with the onset of early spring conditions forced the suspension of the drill program. Drilling is planned to resume once Geotech’s VTEMmax airborne EM survey and summer field program have been concluded.

200-square kilometer, VTEMmax survey

Geotech’s Versatile Time Domain Electromatic airborne system (VTEMmax) has been contracted to identify additional EM targets, such as Smoke Lake, across the entire 200-square kilometer Tyko property.

The survey comprises greater than 3,000-line kilometers of closely spaced (100-meter) flight lines. Although the Smoke Lake EM anomaly was originally found at the end of a 1980’s era survey, EM surveying was not conducted to the south of the Smoke Lake, despite there being another nickel-copper showing (Shabotik, with up to 1.0% Ni, see press release August 19, 2019) occurring in this area.

A summer mapping, prospecting and soil sampling program has been mobilized to ground truth VTEMmax anomalies identified and increase the knowledge base of the larger Smoke Lake area as well as other select areas. The vast majority of the Tyko project has seen little to no exploration, or even government mapping.

*Nickel Equivalent (“Ni_Eq”) and Copper Equivalent (“Cu_Eq”)

Nickel and copper 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 (US$3.00 per pound) for copper, US$15,432 per tonne (US$7.00 per pound) for nickel and US$30,865 per tonne (US$14 per pound) for Cobalt. This calculation is consistent with the commodity prices used in the Company’s September 2019 NI 43-101 Kaukua resource estimate.

QA/QC

The Phase II 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. The drill core samples were transported by company staff the Company’s core handling facility, to Actlabs laboratory in Thunder Bay, Ontario. Actlabs, is an accredited lab and are ISO compliant (ISO 9001:2015, ISO/IEC 17025:2017). PGE analysis was performed using a 30 grams fire assay with an ICP-MS or ICP-OES finish. Multi-element analyses, including copper and nickel were analysed by four acid digestion using 0.5 grams with an ICP-MS or ICP-OES 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.
