Highlights:
- Mann West Significantly Larger than Initial Crawford Resource:

- Exploration Target1 of an additional 0.5-1.0 billion tonnes grading 0.20-0.22% nickel
-
Mann West is the third of eight new nickel resources expected to be published in 2025
1 the potential quantity and grade is conceptual in nature; there has been insufficient exploration to define a mineral resource; it is uncertain if further exploration will result in the target being delineated as a mineral resource (also see below). |
Mann West Mineral Resource Estimate
For the initial Mineral Resource Estimate, a total of 16,833 metres of core drilling in 37 drill holes were utilized to calculate the Mann West Resources in two categories as provided in Table 1. Indicated Resources totalled 406 million tonnes grading 0.23% nickel, for a total of 0.95 million tonnes of contained nickel and Inferred Resources totalled 599 million tonnes grading 0.22% nickel, for a total of 1.31 million tonnes of contained nickel. The approximate dimensions of the resource are 1.9 kilometres long, 800 metres wide, extending to 500 metres deep and remaining open to the northwest and at depth. An additional 0.5 – 1.0 billion tonnes grading between 0.20% and 0.22% nickel remain as an Exploration Target, pending further drilling. This Exploration Target is based on core drilling by the Company, the geophysical survey on the Project, and the understanding and calculation of the current MRE. Within the resource, a
The Exploration Target was derived by modelling the identified nickel sulphide mineralization within the current estimation envelope but outside of the current Mineral Resource Estimate area.
The volume of the modelled Exploration Target area determines the potential tonnage statement in the Exploration Target. The grade range given in the Exploration Target is determined with consideration to the drill core results within the modelled Exploration Target area, consideration of the geological setting in a well understood nickel deposit type where grades are observed and well understood, and based on the experience of the Company and the Qualified Persons. The potential tonnages and grades are conceptual in nature and are based on drill holes and geophysical results that define the approximate length, thickness, depth and grade of the Exploration Target. There has been insufficient exploration to define a current mineral resource and the Company cautions that there is a risk that further exploration will not result in the delineation of a current mineral resource.
Drilling at Mann West was completed in 2023 and 2024. The 2024 campaign successfully completed the goal of infilling previous sections to allow for the definition of an initial mineral resource estimate, gain understanding on the geology of the deposit, as well as systematically collecting samples for mineralogical analysis that have started to help define the potential of nickel recovery (see

The independent Qualified Person for the Mineral Resource Estimate ("MRE"), as defined by National Instrument 43-101 ("NI 43-101"), is Dr. |
2. |
The quantity and grade of reported Inferred Resources in this MRE are uncertain in nature and there has been insufficient exploration to define these Inferred Resources as Indicated or Measured. However, it is reasonably expected that the majority of Inferred Mineral Resources could be upgraded to Indicated Mineral Resources with continued exploration. |
3. |
A cut-off grade of 0.10% Ni was used to define potentially economic material for inclusion within the MRE. Cut-offs were determined on the based on core assay geostatistics and drill core lithologies for the deposit, and by comparison to analogous nickel deposit types. |
4. |
Geological and block models for the MRE used data from a total of 37 surface drill holes, completed by |
5. |
Estimates have been rounded to two significant figures. |
6. |
The MRE was prepared following the CIM Estimation of Mineral Resources & Mineral Reserves Best Practice Guidelines ( |
7. |
The geological model as applied to the MRE comprises three mineralized domains hosted by variably serpentinized ultramafic rocks: a relatively higher-grade core (dunite), a lower grade (peridotite), and a PGE-rich pyroxenite "reef". Individual wireframes were created for each domain in Leapfrog Geo 2024.1 software. |
8. |
A 20 m x 20 m x 15 m block model was created, and samples were composited at 7.5 m intervals. Grade estimation from drill hole data was carried out for Ni, Co, Fe, Cr, S, Pd and Pt using the Ordinary Kriging interpolation method in Isatis 2024.04 software. |
9. |
The MRE has been constrained by a conceptual pit envelope that was developed using the following optimization parameters. Metal prices used were |
10. |
Grade estimation was validated by comparison of input and output statistics (Nearest Neighbour and Inverse Distance Squared methods), swath plot analysis, cross-plots of declustered samples against the nearest OK estimate, and by visual inspection of the assay data, block model, and grade shells in cross-sections. |
11. |
Density estimation was carried out for the mineralized domains using the Ordinary Kriging interpolation method, based on 1,740 specific gravity measurements collected during the core logging process, using the same block model parameters of the grade estimation. As a reference, the average estimated density value within dunite is 2.64 g/cm3 (t/m3), while the peridotite domain yielded an average of 2.74 g/cm3 (t/m3), and the PGE "reef" domain an average of 3.05 g/cm3 (t/m3). |
Next Steps at Mann West:
- A technical report with respect to the Mineral Resource Estimate disclosed today will be filed within 45 days.
- Infill drilling at the property will aim to increase and upgrade inferred resources in the next drilling campaign.
- Mineralogical and metallurgical analysis will continue to better understand and estimate metal recoveries.
