Good recovery figures from Ungava tests

Metallurgical testing commissioned by Canadian Royalties (CZZ-T) on mineralization from its Ungava nickel-copper projects has shown high base metal and platinum-group recoveries.

Testing by SGS Lakefield Laboratories on drill core from the project established that conventional flotation works on sulphide mineralization from the Mesamax, Expo and Mequillon deposits. Mineralization from the different deposits had a wide range of characteristics, but all types behaved similarly in flotation cells.

Bulk nickel-copper concentration was tested but final work evaluated only separate nickel and copper concentrates, which would be an easier sell to smelters in any event.

Nickel recoveries ranged from 75% to 82% and copper recoveries from 83% to 98%. Platinum and palladium were recovered in both concentrates, but mainly in the nickel concentrate. Total recoveries were 60% to 80% for platinum and 80% to 93 % for palladium.
