NICKEL CREEK PLATINUM EXTENDS HIGH GRADE NICKEL-COPPER-PGE MINERALIZATION AT ARCH TARGET - DRILLS 2.57% Ni, 1.61% Cu AND 2.35 g/t TPM OVER 3.84 m

HIGHLIGHTS OF THE DRILL RESULTS AT ARCH:

• A massive sulphide interval grading 2.57% nickel (Ni), 1.61% copper (Cu) and 2.35 g/t Total Precious Metals (TPM) over 3.84 m was intersected down-dip of semi-massive to massive sulphide mineralization drilled in 2021 (see Photo 1 for core sample and Table 1 for drill intersection details).
• Significant disseminated + semi-massive sulphide intervals grading 0.29 to 0.67% Ni, 0.08 to 0.43% Cu and 0.43 to 1.64 g/t TPM over 6.25 to 78.95 m intervals in 7 holes (see Table 1 for details).
• Geophysics results show untested conductivity down-dip and along strike of current drilling.
• Near surface massive to disseminated sulphide mineralization at depths of 7-170 m.

TORONTO, April 11, 2023 /PRNewswire/ - Nickel Creek Platinum Corp. (TSX: NCP) (OTCQB: NCPCF) ("Nickel Creek" or the "Company") is pleased to announce the results from its 2022 drilling and geophysics program on the Arch Target conducted during the period of July-October 2022 in Yukon, Canada. The timing of the release of these results was largely impacted by the unprecedented volume of samples from exploration projects throughout Yukon submitted to the ALS preparation lab in Whitehorse.

The drilling component of the 2022 exploration program comprised 18 holes totalling 2,975 metres (m), of which 10 holes totalling 1,265 m were drilled on the Arch Target at the Nickel Shäw Project. The drilling at Arch was successful in extending massive to disseminated Ni-Cu sulphide mineralization at depth and along strike from holes drilled in 2021. See Figure 1 for a general plan map of the areas. Eight (8) holes were drilled on the Wellgreen deposit (1,710 m) to convert inferred mineral resources to indicated mineral resources and to collect additional geotechnical and hydrogeological data.  The 1,710 metres of drilling at Wellgreen was carried out to support the completion of a Prefeasibility Study (PFS) which is expected to be completed by July 2023.

"We have demonstrated the continuity of sulphide mineralization at the Arch Target including its significant Nickel, Copper, Precious Metals and Sulphur grades. This target occurs at shallow depths and is currently being assessed to determine if a maiden inferred resource can be outlined here." said Stuart Harshaw, President and CEO of Nickel Creek Platinum.  "The PFS will not include the Arch Target when produced in Q3 this year but we are excited by the opportunity for additional higher-grade mineralization at our Nickel Shäw property."

Table 1: Arch Drilling Summary

Note: All intervals listed are down-hole core lengths, not true widths; interval grades are length weighted. A cut-off grade of 1.0% Ni was applied for the massive sulphide and 0.25% Ni for the disseminated sulphide.

The Arch ultramafic sill has been the subject of several historical exploration campaigns and has had various surveys, including ground electromagnetics (EM) and magnetics, helicopter EM and magnetics (Dighem), soil geochemistry, trenching and limited diamond drilling (three holes totalling 136m).  Drilling in 2021 at the Arch Target intersected significant massive to semi-massive sulphide in six holes. Grades up to 3.85% Ni, 1.37% Cu and 3.97 g/t TPM over 3.45m were returned. Disseminated sulphide along with net-textured, blebby and interstitial sulphide variably occurs above the high-grade zones with combined massive sulphide and disseminated intervals grading up to 1.41% Ni, 0.55% Cu and 2.49 g/t TPM over 11.95m.

During the 2022 drill program, a massive sulphide interval grading 2.57% Ni, 1.61% Cu and 2.35 g/t TPM over 3.84 m was intersected in ASD22-016, drilled down-dip of semi-massive to massive sulphide mineralization drilled in 2021. This is part of a larger interval grading 1.37% Ni, 0.89% Cu and 0.89 g/t TPM over 8.73m. Significant disseminated and semi-massive sulphide intervals grading 0.29 to 0.67% Ni, 0.08 to 0.43% Cu and 0.43 to 1.64 g/t TPM over 6.25 to 78.95 m intervals in seven (7) holes. These intersections also contain significant sulphur (S) levels, a key determining factor in Ni recovery at the Wellgreen deposit (see Table 1 for details). These intersections occur at shallow depths (7-170m) over a strike length of approximately 450m. Work is in progress to determine if sulphide mineralization at Arch can be classified as a maiden inferred resource. 

Sulphide mineralization at Arch occurs at the base of an outcropping ultramafic sill ("Arch Sill") that is centred four kilometres west-northwest of the Wellgreen deposit. The sill is approximately 100 m thick and the base (northeast contact) dips subparallel to the slope at 55-75 degrees to the south-southwest. Massive and semi-massive sulphide mineralization is related to a thin (<2 metres) marginal gabbro unit that occurs below a distinctive Mottled Peridotite unit. The high-grade sulphide occurs at the marginal gabbro/footwall contact. Footwall rocks typically consist of Hasen Creek Formation meta-sediments. The ultramafic Arch Sill is believed to be contemporaneous with the Permo-Triassic ultramafic intrusion hosting the Wellgreen deposit. The massive sulphide intersection in 2022 hole ASD22-016 is associated with a potential peridotite feeder dyke occurring below the main sill with an 8.73-m core length of combined peridotite and massive sulphide. See Figure 2 for a plan map of Arch drill hole locations. See Figure 3 for a general east-west longitudinal section showing geology and drill intersections through the Arch area.

One (1) 2022 Arch hole was surveyed by borehole electromagnetics (EM) along with 14 surface EM lines totalling approximately 4,200 m. Geophysical results show untested conductivity down-dip and to the northeast of the 2021/22 drilling. Field-checking of near-surface conductors to the northeast is required. Diamond drilling was performed by Superior Diamond Drilling and the EM survey was completed by SJ Geophysics.

As part of the 2022 drill program, existing drill trails were upgraded to allow truck access to all drill sites.

Analytical quality assurance and quality control ("QAQC") included submission of blanks and standards. Various standards were submitted that are appropriate for both low-grade and high-grade Ni-Cu-PM mineralization. Results from the standards and blanks were reviewed and in the opinion of the Qualified Person, the analytical results pass QAQC review for base metals and PMs in the low-grade type (disseminated sulphide) mineralization as well as the base metals in the high-grade (semi-massive to massive sulphide) mineralization. Analytical QAQC for precious metals in the higher-grade mineralization is still pending. Sample preparation was completed at the ALS facility in Whitehorse, Yukon and analysis was completed at the ALS laboratory in North Vancouver, British Columbia. Samples were analyzed by 4-acid digestion and ICP-AES (ALS method MEICP-61) with platinum, palladium and gold analysis by fire assay with ICP-AES finish (ALS method PGM-ICP23).

Drilling at the Wellgreen deposit was completed to facilitate hydrogeology studies, geotechnical studies and resource conversion. This work is part of the ongoing PFS that is expected to be completed by July 2023. Borehole geophysics (EM) were completed on three (3) 2022 holes at the Wellgreen deposit. This information is being reviewed in the context of the geological model to determine if high-grade targets are present below the current contemplated pit.
