- CIM definitions (2014) and CIM Estimation of Mineral Resources & Mineral Reserves Best Practice Guidelines (2019) were followed for Mineral Resources.
- Mineral Resources were estimated at NSR cutoff values of US$49.70 for open pit and US$94.50 for underground.
- NSR values were calculated using long-term metal prices of US$8.00/lb for Nickel, $US3.30/lb for Copper, US$20.60/lb of Cobalt, US$900/oz Platinum, and US$1,910/oz Palladium.
- Metallurgical recoveries used in the NSR calculation were 91% for Nickel, 96% for Copper, 90% for Cobalt, 50% for Platinum and 81% for Palladium.
- Open pit Mineral Resources are reported at a base case NSR value of US$49.70 within a conceptual pit.
- Underground Mineral Resources were estimated using a minimum true width of 2.5 metres and US$94.50 NSR value.
- The independent Qualified Person for the current Mineral Resource estimate is Mr. Jamie Lavigne, P. Geo.
- The Mineral Resource block model was peer-reviewed by Allan Armitage, PhD, P.Geo of SGS Geological Services. Dr. Armitage is an Independent Qualified Person as defined in NI-43-101.
- Mineral Resources, which are not Mineral Reserves, do not have demonstrated economic viability.
- All figures are rounded to reflect the relative accuracy of the estimate. Numbers may not add due to rounding
