Regarding the gold and silver ( factored into the Zinc Eq), this taken from the 17th Dec Red River announcement
'
The metallurgical factors applied in the economic evaluations are based on Thalanga mine historicals; zinc concentrate 89% recovery & 56% concentrate grade, lead concentrate 75% recovery & 60% concentrate grade plus 50% recovery of silver & 30% recovery of gold into the lead concentrate, copper concentrate 80% recovery & 26% concentrate grade plus 15% recovery of silver & 17% recovery of gold into the copper concentrate. There are no material deleterious elements expected that will prevent the saleability of the concentrates "
No doubt in the recent plant start up and ramp -up experience , they will be "tinkering" with the metallurgy benefication process to optimize the recovery process of each element , and an upscaling ( even modest ) would be welcomed and come as no surprise . March Quarter figures may reveal .
