Power Nickel Follows Up Release of NI 43-101 Compliant Mineral Resource Estimate on the Nisk Nickel Project With Commencement of Second Round of Drilling

TORONTO, ON / ACCESSWIRE / September 22, 2022 / Power Nickel Inc. (the "Company" or "Power Nickel") (TSXV:PNPN)(OTCQB:CMETF)(Frankfurt:IVVI) is pleased to follow up on the recent release of the NI 43-101 Technical Report and Mineral Resource Estimate ("MRE") on the "Nisk" Nickel project with the commencement of the second round of drilling. The NI 43-101 Technical Report and Mineral Resources Estimate for the Nisk Project was filed on SEDAR on August 30, 2022.

The Nisk Project is located in the southern portion of the Eeyo Istchee James Bay territory, Québec, a region that is the site of a number of mining projects (Figure 1) and improving infrastructure (Figure 2).[1]

[1] References to nearby properties is for information purposes only and there is no assurance that Power Nickel will achieve the same results as on the nearby properties.

Power Nickel completed the acquisition of its option to acquire up to 80% of the Nisk Project from Critical Elements Lithium Corp. (CRE:TSXV). The Nisk Project comprises a large land position (20 kilometres of strike length) with numerous high-grade Nickel intercepts. Since completion of the option, Power Nickel retained 3DGeo Solution Inc to create a geological model of the Nisk Project and used this as a guide to the very successful initial Power Nickel 2400-metre drill program completed last December and reported in March of 2022. (See figure 3 below, modified from Press Release dated March 30, 2022).

On the basis of this drill program and the historical drill results, 3DGeo Solution Inc was mandated to conduct a Mineral Resource Estimate and to prepare a NI 43-101 Technical Report on the Nisk Project. Engineering work related to defining a constraining pit shell and underground mineable shapes was contracted to InnovExplo Inc. The Highlights of the Mineral Resource Estimate are below.

Notes to Accompany Mineral Resource Table:

1. The Independent Qualified Persons for the purposes of this Mineral Resource Estimate (MRE), as defined in NI 43-101, is Kenneth Williamson, P.Geo.. (OGQ # 1490) of Solution 3DGéo inc. The effective date of the estimate is May 17, 2022.

2. The estimate of the mineral resources of the Nisk Project complies with the "CIM Estimation of Mineral Resources and Mineral Reserves Best Practice Guidelines" of November 29, 2019. The Mineral Resources were estimated in accordance with the Canadian Institute of Mining, Metallurgy, and Petroleum (CIM), CIM Standards on Mineral Resources and Reserves, Definitions (2014), and Best Practices Guidelines (2019) prepared by the CIM Standing Committee on Reserve Definitions and adopted by the CIM Council.

3. These mineral resources are not mineral reserves since their economic viability has not been demonstrated.

4. The resources are presented before dilution and in-situ and are considered to have reasonable prospects of economic extraction. Isolated and discontinuous blocks with a grade greater than the selected cut-off grade are excluded from the estimate of underground mineral resources. The blocks that must be included, i.e., isolated blocks with a grade below the cut-off grade located within potentially mineable volumes, have been included in the mineral resource estimate.

5. As of May 17, 2022, the database included a total of 66 drill holes (59 historic and 7 recent 2021 drill holes) totaling 15,266.3 meters of drilling.

6. A value of half of the assay lab detection limit for each element was used as a grade for the un-assayed core.

7. The assays were grouped within the mineralized domains in composites of 1.00 meters in length.

8. The block model was prepared using Leapfrog® Geo and Edge software. The block model consists of 2-meter parent blocks and sub-blocks of 1 meter. The block model has a dip azimuth of 340°.

9. An interpolation according to the "inverse distance squared" ("ID2") method was performed to estimate the grades in the interpreted mineralized volume.

10. An interpolation according to the "inverse distance squared" ("ID2") method was performed to estimate the Density (SG) in the interpreted mineralized volume. Sample intervals with missing SG values were calculated based on a strong correlation with %Ni. The calculation used was SG = (0.7001 x %Ni) + 2.6751.

11. The "Open Pit" mineral resources are presented at a cut-off grade of 0.33 %NiEq and are confined within a "Whittle" pit shell. The "Underground" mineral resources are presented at a cut-off grade of 0.91 %NiEq and are confined within volumes defined using "DSO" (Deswik Stope Shape Optimizer). These volumes correspond to groups of contiguous blocks with a reasonable size to be exploited by underground mining methods.

12. The engineering work required for the cut-off grade estimation and the creation of the DSO volumes were performed by InnovExplo Inc., and the following economic parameters were used: US $8.00/lb Nickel, $3.00/lb Cu, $25.00/lb Cobalt, $1000/Oz Platinum, $1000/Oz Palladium, $1300/Oz Gold, and $17.00/Oz Silver; Exchange rate of USD/CAD 1.30, metallurgical recovery of 85%, total processing cost CA $40.00/t, mining cost CA $6.00/t, mining overburden cost CA $4.20/t, underground mining cost CA $110.00/t, G&A cost CA $12.20/t, northern logistics costs CA $10.00/t. It should be noted that the G&A cost could be underestimated depending on the extraction sequence chosen.

13. The independent qualified person is not aware of any environmental, licensing, legal, title-related, tax, socio-political or marketing-related issue, or any other relevant issue that could have a material impact on the estimate of mineral resources.

14. The numbers of tonnes are rounded to the nearest hundred to reflect uncertainties, which may cause slight differences.

Figure 4 shows the grade of the Nickel Equivalent (%NiEq) mineral resources and Figure 5 shows the mineral resource classification (indicated and inferred). Note that portions of the deposit still contain unclassified mineral potential and requires more in-fill drilling to potentially include this in a future updated MRE.

Figure 6 below shows the drill targets for phase 2 of the drilling at Nisk.

As a follow-up to the filing of the Technical Report, 3DGeo Solution (3DGS) was mandated to design a drilling program aiming at infilling gaps within the defined resource area and to expand the known mineralization along identified higher-grade shoots.

This second round of drilling, consisting of approximately 5,500 meters of drilling, aims at reaching over 15 of these different targets. GeoVector Management Inc is mandated as the operator of the current drilling program.

"We are very excited to get back to drilling and building on our resource at Nisk. The initial round of drilling was done largely to verify the historic resource and allow us to post the inaugural NI 43-101 Technical Report and MRE. This round, based on what we've learned from the MRE study, will enable us to better explore and we hope to expand the resource as we look to demonstrate Nisk has the potential to become Canada's next Nickel Mine. The plan is to drill around 5,000 Metres but will adjust that to opportunities on the ground. We would expect the drilling program to continue into December and we will provide updates as progress dictates." commented Terry Lynch CEO of Power Nickel
