Notes:
| 1. | All tabulated data have been rounded and as a result minor computational errors may occur. |
| 2. | Mineral Resources, which are not Mineral Reserves, have no demonstrated economic viability. There is no guarantee that all or any part of the Mineral Resource will be converted into a Mineral Reserve. The estimate of Mineral Resources may be materially affected by geology, environment, permitting, legal title, taxation, socio-political, marketing, or other relevant issues. |
| 3. | kt = thousand tonnes, Mt = Million tonnes, Mlbs = million pounds |
| 4. | The 2026 MRE has been prepared in accordance with the CIM Definition Standards (2014) and CIM Best Practice Guidelines (2019) with a data cut-off of September 21, 2026, and an effective date of September 28, 2026. |
| 5. | Mineral Resources are reported at a cut-off value of US$75/t NSR (Net Smelter Return) defined as received value of final metal recovered minus off-site costs, and a minimum thickness of 1.5 metres. |
| 6. | Mineral Resources are estimated using long-term prices of US$9.10/lb Ni, US$5.10/lb Cu, US$20.00/lb Co. The same metal prices were used in NSR calculations. |
| 7. | Mineral Resources are estimated using nickel, copper and cobalt recoveries of 55.6%, 96.1%, and 60.2%, respectively, derived from metallurgical studies which consider a two-concentrate scenario. |
| 8. | Payabilities and off-site treatment and refining costs were derived from an independent marketing study commissioned by NexMetals. |
| 9. | Bulk density has been estimated in the block model based on an extensive data set of measurements taken from drillhole cores. The average density is 3.51 t/m3 for the Upper vein and 3.38 t/m3 for the Lower vein. |
| 10. | Mineral Resources are reported using NSR values which assume mining costs of US$47.60/tonne, concentrate processing costs of US$20.00/tonne and G&A of US$5.50/tonne. |
| 11. | Areas depleted or sterilized by mining were removed from the mineral resource as well as an interpreted dyke. |
| 12. | There are no Mineral Reserves. |
| 13. | Copper equivalent is calculated using the formula CuEq =(Cu%*96.4+Ni%*87.0+Co%*132.7)/96.4. |
The table reports Selebi Main only. The updated Selebi North mineral resource estimate is pending and is not included. Totals may not add up due to rounding.
