NEWFOUNDLAND – Buchans Minerals Corp. of Windsor, NS, has received a detailed open pit mine plan for its Lundberg and Engineer House base metals deposits in central Newfoundland. Wardrop prepared the plans based on a 5,000-t/d operation.
The pit design includes 16.6 million tonnes of the existing resource. The average grades over the life of mine is 1.65% Zn, 0.70% Pb, 0.41% Cu, 5.97 g/t Ag, 0.07 g/t Au and 1.25% Ba. It is estimated that the life of mine will be approximately 10 years and the average stripping ratio is estimated to be 3.20:1 with 53.3 million tonnes of waste material being moved.
The open pit is located just west of the town of Buchans, and the final open pit is anticipated to be comprised of 20 benches down to a depth of 200 metres and a final footprint having approximate dimensions of 800 metres north-south and 900 metres east-west. Three dimensional images of the mine plan can be viewed on the Company’s website at http://www.BuchansMinerals.com.
The original resource estimate with an inferred resource of 20.7 million tonnes grading 1.68% Zn, 0.72% Pb, 0.38% Cu, 5.92 g/t Ag and 0.07 g/t Au at Lundberg and 1.1 million tonnes grading 2.04% Zn, 0.85% Pb, 0.82% Cu, 9.79 g/t Ag and 0.12 g/t Au at Engine House.
