SPC Nickel Announces Maiden Mineral Resource on the West Graham Project
SUDBURY, Jan. 17, 2024 - SPC Nickel Corp. (TSXV: SPC) ("SPC Nickel" or the "Company"), is pleased to announce the maiden Mineral Resource Estimate ("MRE") for the West Graham Project ("West Graham" or the "Project"), part of the Company's large-scale Ni-Cu property (Figure 1 & 2) in the southwest corner of the Sudbury Basin, referred to as the Lockerby East Property.
The MRE shows Indicated Resources of 224.8 million pounds of contained nickel and 155.0 million pounds of contained copper and further Inferred Resources of 86.2 million pounds of contained nickel and 57.5 million pounds of contained copper (Table 3).
The MRE, in accordance with National Instrument 43-101 ("NI 43-101") is effective as of December 4, 2023, was produced following the consolidation of the Project in January 2023 (see News Release dated January 23, 2023) through an agreement with Vale Canada. Following that consolidation, SPC Nickel completed a diamond drilling program (67 holes totalling 14,180 metres) in connection with producing the MRE.
- In-Pit Resource at a 0.3% NiEq1 Cutoff Grade
- Indicated Resource of 19.3 Mt at 0.42% Ni, 0.28% Cu (0.57% NiEq2)
- Inferred Resource of 3.3 Mt at 0.37% Ni, 0.28% Cu (0.53% NiEq2)
- In-Pit Resource extends from surface to a vertical depth of 435 metres.
- Future Expansion: Potential to expand the 'higher-grade' (>0.9% NiEq2) zones within the In-Pit Resource with additional infill drilling.
- Out-of-Pit Resource at a 0.7% NiEq1 Cutoff Grade
- Indicated Resource of 3.2 Mt at 0.63% Ni, 0.47% Cu (0.92% NiEq2)
- Inferred Resource of 3.9 Mt at 0.69% Ni, 0.43% Cu (0.97% NiEq2)
- Exploration Upside: Significant potential to expand the Out-of-Pit Resource with additional infill drilling.

Grant Mourre, CEO and President of SPC Nickel commented, "SPC Nickel is very pleased to deliver this maiden Mineral Resource representing yet another major milestone for the Company as we continue to grow and advance the West Graham Project. To produce a Mineral Resource Estimate within 12 months of signing an agreement to consolidate the asset with Vale in January 2023, is a tremendous achievement by our team.
The geometry of the mineralization at West Graham, its amenability to low-cost open-pit mining methods, the availability of local skilled labour, proximity to power, transportation and processing infrastructure, including both nickel sulphide mills and smelters, favourably positions the project for a near-term path to production. The West Graham Deposit, as well as the larger Lockerby East Property, retains remarkable exploration upside and our maiden Mineral Resource is a vital step towards unlocking and realising that potential."
The Mineral Resources at West Graham were estimated by SGS Geological Services and are summarized in Table 1. Sensitivity to cutoff grade is summarized in Table 2, and contained metal summarized in Table 3. Mineral Resources include near surface mineralization with potential for open-pit mining, as well as higher grade mineralization amenable to conventional underground mining methods (Figure 2). The full technical report, which is being prepared in accordance with NI 43-101 - Standards of Disclosure for Mineral Projects will be available on SEDAR (www.sedar.com) under the Company's issuer profile within 45 days from this news release.

In addition to the West Graham Deposit, the property also hosts the 100% owned high-grade LKE Deposit (formerly called the Lockerby East Deposit). Located 200 metres down-dip of the West Graham Resource (Figure 2), the deposit is comprised of a lens of high-grade Ni-Cu-PGM massive sulphide where historical drilling returned values as high as 5.60% Ni and 1.26% Cu over a core length of 10.0 metres (see reference section). In 2009, First Nickel Inc. published a historical resource for the LKE Deposit, that contained 0.18 Mt at 2.32% Ni, 0.78% Cu in the indicated category and 0.04 Mt at 2.90% Ni, 0.80% Cu in the inferred category (see reference section). SGS Geological Services is currently updating the historical resource to current standards based on a validated historical database and a revised resource model and will incorporate this resource estimate update in the full technical report.
Mineral Resource Estimate Notes:
| (1) | The Mineral Resource Estimate was estimated by Allan Armitage, Ph.D., P. Geo. of SGS Geological Services and is an independent Qualified Person as defined by NI 43-101. Dr Armitage conducted a site visit to the Lockerby East Property on July 24, 2023. |
| (2) | The classification of the current Mineral Resource Estimates for the West Graham Deposit into Indicated and Inferred is consistent with current 2014 CIM Definition Standards - For Mineral Resources and Mineral Reserves. |
| (3) | All figures are rounded to reflect the relative accuracy of the estimate and numbers may not add due to rounding. |
| (4) | All mineral resources are presented undiluted and in situ, constrained by continuous 3D wireframe models (the constraining volumes), and are considered to have reasonable prospects for eventual economic extraction. |
| (5) | Mineral resources which are not mineral reserves do not have demonstrated economic viability. An Inferred Mineral Resource has a lower level of confidence than that applying to an Indicated Mineral Resource and must not be converted to a Mineral Reserve. It is reasonably expected that most of the Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued exploration. |
| (6) | The validated database for the West Graham Deposit provided by SPC Nickel for the MRE includes data for 560 surface and underground diamond drill holes and 26 surface rock channels totalling 182,936 m. The database totals 20,294 assay intervals representing 27,388 m of drilling and channeling. The database includes data for 85 drill holes completed by SPC totalling 19,393 m and including 7,093 assay samples. The average assay sample length of all drilling is 1.35 m. |
| (7) | The West Graham resource model is based on 256 mineralized intercepts from 236 drill holes and 17 rock channels, including mineralized intercepts from all 85 drill holes completed by SPC. The mineralized database included 7,953 assay samples, average length of 1.30 m and 7,119 1.5 m composites. |
| (8) | The West Graham Mineral Resource Estimate is based on a three-dimensional ("3D") resource model, constructed in GEOVIA GEMS version 6.8.3 software ("GEMS"). |
| (9) | Grades for nickel, copper, cobalt, platinum, palladium, gold and silver were estimated were interpolated into a block model, with block dimensions of 10 * x 5 (y) x 5 (z) m, using 1.5 m capped composites assigned to that model. To generate grade within the blocks, the inverse distance squared (ID2) interpolation method was used. The resource estimate search parameters are based on drill hole spacing, and size, shape and orientation of the resource domain. The classification of resource into Inferred and Indicated is based primarily on drill hole spacing. |
| (10) | An average density value for the West Graham Deposit was assigned based on a database of 6,295 mineralized samples. A value of 2.92 is used for West Graham. Values ranging from 2.85 to 3.00 are used for waste. Waste densities are based on a database of 7,039 samples. |
| (11) | The West Graham Deposit mineralization is considered amenable to open-pit and underground extraction. |
| (12) | It is envisioned that parts of the West Graham Deposit may be mined using open pit mining methods. In-pit mineral resources for the West Graham Deposit are reported at a base case cutoff grade of 0.3 % NiEq within a conceptual pit shell. Whittle™ pit optimization software (GEOVIA Whittle 2022) was used for pit optimization. The results from the pit optimization are used solely for the purpose of testing the "reasonable prospects for economic extraction" by an open-pit and do not represent an attempt to estimate mineral reserves. There are no mineral reserves on the Property. The results are used as a guide to assist in the preparation of a Mineral Resource statement and to select an appropriate resource reporting cutoff grade. The West Graham in-pit Mineral Resource grade blocks are quantified above the base case cutoff grade, above the constraining pit shell, below topography and within the constraining mineralized domain (the constraining volumes). |
| (13) | Underground Mineral Resources for the West Graham Deposit are estimated from out of the pit shell and are reported at a base case cutoff grade of 0.7 % NiEq. The West Graham underground resource grade blocks were quantified above the base case cutoff grade, out of the constraining pit shell and within the constraining mineralized domain (the constraining volume). |
| (14) | Based on the size, shape and orientation of the deposit, it is envisioned that the West Graham underground resource may be mined using the longhole open stoping mining method (a bulk mining method that has long been utilized in the Sudbury region). |
| (15) | NiEq cutoff grades consider metal prices of $9.50/lb Ni, $3.50/lb Cu, $22.00/lb Co, $1000/oz Pt, $1,800/oz Pd and $1,700/oz Au and consider metal recoveries of 90% for Ni, 90% for copper, 56% for Co, 69% for Pt, 68% for Pd and 68% for Au. Silver is not used. |
| (16) | NiEq grades are calculated using this formula: Ni (%) + [Cu (%) * 0.369] + [Co (%) * 2.318] + [Pt / 31.1 * 4.779] + [Pd / 31.1 * 8.602] + [Au / 31.1 * 8.124] with price assumptions of $9.50/lb Ni, $3.50/lb Cu, $22.00/lb Co, $1000/oz Pt, $1,800/oz Pd and $1,700/oz Au. Silver is not used. |
| (17) | For the West Graham Deposit, pit optimization and the in-pit base case cutoff grade of 0.3% NiEq considers a mining cost of US$2.50/t rock and processing, treatment and refining, transportation and G&A cost of US$38.00/t mineralized material, and an overall pit slope of 55 degrees, metal prices and process recoveries. The underground base case cutoff grade of 0.7 % NiEq considers a mining cost of US$45.00/t rock and processing, treatment and refining, transportation, G&A cost of US$42.50/t mineralized material and process recoveries. |
| (18) | The estimate of Mineral Resources may be materially affected by environmental, permitting, legal, title, taxation, socio-political, marketing, or other relevant issues. |
