Palladium One Expands the Tyko Sulphide Nickel-Copper Project to 24,500 hectares and Completes VTEM Survey

KEY HIGHLIGHTS

• Two Earn-in agreements expand the Tyko Nickel-Copper Project by 950 hectares
• Additionally, 3,500 hectares were purchased from the original Optionors of the Tyko Project.
• Tyko Nickel-Copper Project currently over 24,500 hectares
• 3,100-kilometer airborne Electro Magnetic (VTEMmax) geophysical survey completed
• Summer exploration field crews are onsite conducting reconnaissance mapping, prospecting and soil sampling. The first 1,000 soil samples have been sent for assaying, results pending

Toronto, July 27, 2021 - The footprint of the Tyko Nickel-Copper Project, which returned drill intercepts from massive magmatic sulphide of up to 9.9% Nickel equivalent ("Ni_Eq"), (23.0% Copper equivalent, 30.1 g/t Gold equivalent*) over 3.8 meters in hole TK21-023 (Table 1) has been expanded by 4,400 hectares, said Palladium One Mining ("Palladium One" or the "Company") (TSXV: PDM) (FSE: 7N11) (OTCQB: NKORF) today.

Tyko has grown from 20,100 hectares to over 24,500 hectares since the Phase II drill program was completed.

An option agreement with First Class Metals Ltd, for the Pickle Lake property, consists of 700 hectares located on the west side of the Tyko project and is proximal to the historic RJ zone which returned up to 1.2% Ni_Eq (2.78% Cu_Eq and 3.6g/t Au_Eq*) over 16.2 meters in hole TK16-002 (see news release April 12, 2016). A second option agreement for the Cupa Lake property with a local prospector consists of 250 hectares and is located 8km east of the Smoke Lake Zone.

President and CEO Derrick Weyrauch commented, "Tyko continues to impress and warrants increased levels of expenditure and exploration. Results to date demonstrate robust mineralization spread over at least 18 kilometers, yet the area has seen virtually no government mapping or exploration. We believe that in addition to the high-grade Smoke Lake zone, there are new zones off nickel-copper mineralization yet to be discovered. We are awaiting result from the 3,100-kilometer airborne Electro Magnetic (VTEMmax) survey which will guide further exploration."

200-square kilometer, VTEMmax survey

Geotech's Versatile Time Domain Electromagnetic airborne system (VTEMmax) survey has been completed across the entire Tyko project. The survey comprised greater than 3,100-line kilometers of closely spaced (100-meter) flight lines. It is the most comprehensive and sensitive airborne geophysical survey ever flown on the Tyko property and covered large areas for which no airborne Electro Magnetic surveys had ever been flown, including the area surrounding the Shabotik showing, having up to 1.0% Nickel, see press release August 19, 2019.

Summer Field Program

Mapping, prospecting and soil sampling is well underway with 1,000 soil samples having already been submitted to the assay lab. This program is designed to ground truth historic and new geophysical anomalies. The vast majority of the Tyko project has seen little to no exploration, or even government mapping.

(1) Reported widths are "drilled widths" not true widths.

(2) * Au_Equivalent is calculated for comparison purposes using recent spot prices, $8lb nickel, $4.4/lb copper, $19/lb cobalt, $2,700/oz palladium, $1,150/oz platinum, $1,900/oz gold.

(3) **Italicised orange highlighted results are previously released results see news release June 23, 2021

*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.

Transaction Details

First Class Metals Ltd. - Pickle Lake (formerly, Pezim II) Property - 700 hectares - Grant of Earn-In Right

The Company can earn up to an 80% undivided working interest and a royalty Buy-Back Right, in the Earn-In Properties, over a 3-year earn-in period by incurring Canadian Exploration Expenses as follows:

Year 1 - an amount of not less than C$25,000 on or before the 1st anniversary of the Effective Date:

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
