BOLIVIA – Orvana Minerals Corp. of Toronto has made the first commercial shipment of gold-silver doré made since the carbon-in-leach circuit was recommissioned at its Don Mario copper-gold-silver mine in Santa Cruz state. The shipment comprised 11 bars containing about 4,800 oz. of gold and 1,700 oz. of silver.
Recommissioning the C-I-L circuit at the Don Mario mine will boost Orvana’s gold output.
The C-I-L circuit is now fully operational, having poured its first doré on Jan. 22, 2017.
Orvana expects gold recovery to increase to 80% using the C-I-L circuit, compared to 55% from the old flotation-only process. The increased ounces will boost cash flow, allowing the company to pay back the US$7.9 million project financing by the end of fiscal 2017.
Orvana’s operating assets consist of the producing gold-copper-silver El Valle and Carlés mines in northern Spain and the producing gold-copper-silver Don Mario mine in Bolivia. Additional information is available at www.Orvana.com.
