While copper and precious metal upgrades were strong, nickel recovery was limited by mineralogy, with further testing planned. Reasoning: First metallurgical testing on W2 project shows strong copper performance and significant upgrading of precious metals, though nickel recovery remains a challenge. - Positive factor: strong copper recoveries - Positive factor: high-grade copper concentrate produced - Positive factor: meaningful precious metal upgrades - Negative factor: low nickel recovery in cleaner concentrate - Negative factor: nickel hosted in pyrrhotite matrix Facts used in scoring: 6 ## Classification and evidence **Mill Route** Polarity: neutral Definition: Processing via mill or concentrator \(CIL, CIP, tank leach, flotation\). Why it applies: Testing utilized flotation stages and grinding. Evidence · text > utilized a rougher flotation stage **Bench Scale Only** Polarity: negative Definition: Only preliminary bench tests completed — no locked-cycle or pilot work. Why it applies: Initial testing described as open circuit and rougher flotation, with locked cycle testing planned as next step. Evidence · text > Locked cycle testing planned as a next step ## Extracted facts Stored fact records: 6.
