Executive Summary
This section of the NI 43-101 Technical Report discusses recovery methods for nickel resources, specifically comparing sulphide and laterite ores. It notes that sulphide ores can be concentrated using traditional flotation techniques followed by pyrometallurgical extraction, whereas laterites require molten or dissolved processing with higher capital costs. Metallurgical studies on the Beaver block focused on the viability of conventional flotation methods for sulphide nickel ores.
The report highlights challenges with disseminated sulphide ores, particularly fines containing magnesium-rich serpentine minerals that generate slimes and affect smelting. It introduces the CESL Nickel Process, a hydrometallurgical method developed by Teck Resources Ltd since 1994 for treating low-grade sulphide concentrates with high magnesia content. While the CESL process offers high metal extractions and competitive costs, no samples from the Beaver or Lynx blocks have been tested using this method to date.
