SPC Nickel Announces Filing of NI 43-101 Technical Report for the Previously Announced West Graham Maiden Mineral Resource and the Adjacent Updated LKE Resource

SUDBURY, March 4, 2024 - SPC Nickel Corp. (TSXV: SPC) ("SPC Nickel" or the "Company"), is pleased to announce that the Company has filed an independent technical report prepared in accordance with National Instrument 43-101 - Standards of Disclosure for Mineral Projects ("NI 43-101") supporting the previously announced West Graham Mineral Resource Estimate ("MRE") (reported in the Company's news release dated January 17, 2024) and the adjacent updated MRE for the LKE Deposit ("LKE").

The technical report, titled "Mineral Resource Estimates for the West Graham and LKE Deposits, Lockerby East Ni-Cu-PGM Sulphide Property, Sudbury, Ontario Canada" can be found on the Company's website at www.spcnickel.com and under the Company's issuer profile at www.sedarplus.ca. The MRE, in accordance with National Instrument 43-101, is effective as of December 4, 2023.

Highlights:

• LKE: Resource at a 0.9% NiEq¹ Cutoff Grade
  • Indicated Resource of 0.67 Mt at 1.17% Ni, 0.54% Cu (1.59% NiEq²)
  • Inferred Resource of 0.12 Mt at 0.99% Ni, 0.42% Cu (1.39% NiEq²)
• The LKE Resource is strategically located immediately below the existing mining working developed by Falconbridge in the 1990's.
• Exploration Potential: Significant potential to expand the LKE Resource down-dip over a distance of 1,000 metres.
• West Graham: In-Pit Resource at a 0.3% NiEq¹ Cutoff Grade (previously released)
  • Indicated Resource of 19.3 Mt at 0.42% Ni, 0.28% Cu (0.57% NiEq²)
  • Inferred Resource of 3.2 Mt at 0.37% Ni, 0.28% Cu (0.53% NiEq²)
• West Graham: Out-of-Pit Resource at a 0.7% NiEq¹ Cutoff Grade (previously released)
  • Indicated Resource of 3.2 Mt at 0.63% Ni, 0.47% Cu (0.92% NiEq²)
  • Inferred Resource of 3.8 Mt at 0.69% Ni, 0.43% Cu (0.97% NiEq²)

Grant Mourre, CEO and President of SPC Nickel commented, "SPC Nickel is very pleased to deliver this NI43-101 Technical Report representing yet another major milestone for the Company. We believe the combined West Graham and LKE Mineral Resource Estimates along with our positioning at the heart of the Sudbury mining camp, one of the most developed and prolific nickel jurisdictions globally, establishes the Company as one of the best nickel investment opportunities anywhere. In addition to the Company's impressive progress at West Graham, the announcement of an updated resource at LKE combined with the down-dip potential further highlights the vast exploration potential that exists on the Property."

The Mineral Resources at the LKE Project were estimated by SGS Geological Services and are summarized in Table 1. Sensitivity to cut-off grade is summarized in Table 2, and contained metal summarized in Table 3. The LKE MRE was based on a validated historical database containing drill holes completed by both Falconbridge Ltd. (Falconbridge) and First Nickel Inc. (FNI). A revised resource model, economic parameters and cutoff grade were used in the LKE MRE. Since acquiring the property in 2016, the Company has not completed any exploration drilling on the LKE Deposit.

Discovered in 1968 by Falconbridge, the LKE Resource is located approximately 1,500 metres east of the former Lockerby Mine and 200 metres down-dip of the West Graham Resource (Figure 2). Mineralization is predominately contact style, with narrow (less than 5 metres thick) high-grade semi-massive to nearly massive breccia sulphide veins anastomosing proximal to the folded granite footwall contact. LKE sulphide mineralization is characterized by a high pentlandite to pyrrhotite ratio with the overall grade, tenor and PGM content of the mineralization increasing with depth. Historical drilling completed by FNI returned values as high as 5.60% Ni and 1.26% Cu over a core length of 10.0 metres (see reference section below).

In 2016, the Company completed a borehole geophysical program (reported in the Company's news release dated November 21, 2016) on seven historic holes completed by Falconbridge and FNI down-dip of the LKE Resource. The results from the surveys identified a trend of very strong geophysical conductors (2,000-20,000 siemens) over a combined distance of 1,100 metres extending down-dip from the LKE Resource (Figure 3). Of particular interest, is a 200 metre by 700 metre area with several >10,000 siemen conductors that remain virtually untested by drilling. Historical hole GRA-21DE, drilling by Falconbridge in 1988, encountered a thick zone of Ni-Cu-PGM mineralization include several high-grade massive sulphide stringers with extremely high nickel tenors (9.5% -12.3%) along the fringes of the modelled EM conductors.

The Lockerby East Property is located in the heart of the Sudbury Mining District where nine mines are currently in operation and two more are in the development phase. The region benefits from its proximity to well-developed transportation infrastructure including roads, railways, and electrical grid. In addition, the Property is situated close to processing, smelting and refining assets which include two mills, two smelters and one nickel refinery. Local operators include global mining corporations Vale, Glencore and KGHM.
