This examine contains, for the primary time, a 43-101 reserve estimate for gypsum. Complete measured and indicated materials is 5.2 million tonnes grading 91.8% gypsum, and the inferred portion is 790,000 tonnes at 91.2%. ScoZinc signed a gypsum offtake settlement in early November. Earlier research for the Scotia mine designated gypsum as waste rock.
Measured and indicated base metallic assets are 25.5 million tonnes grading 1.89% zinc and 0.99% lead (2.84% zinc-equivalent), with inferred assets at 5 million tonnes grading 1.5% zinc and 0.66% lead (2.13% zinc-equivalent). Confirmed and possible reserves stand at 13.7 million tonnes grading 2.03% zinc and 1.1% lead (3.09% zinc-equivalent).
The mill on the Scotia mine would have a throughput of two,700 t/d to supply a 57% zinc focus and 71% lead focus. 5-year annual manufacturing could be 35 million lb. zinc and 15 million lb. lead in concentrates. All-in sustaining prices are estimated to be 60¢/lb. zinc-equivalent.
The mine, 62 km northeast of Halifax, has been on care and upkeep because the third quarter of 2013. ScoZinc owns 100% of the open pit mine and mill. The challenge is absolutely permitted, and the following step is financing. Business manufacturing may start 9 to 12 months after financing is organized.
