SGS Canada completed a Preliminary Economic Assessment and assigned a NPV of $344 million with an IRR of 137%, to the Frances Creek project. The company is designing a new barium API pilot plant, with the goal of reducing the capital required, from the $36 million over three years, stated in the PEA. Voyageur’s plan is to build a lower cost production facility, fast track production, process the 2,000 tonnes of barium sulfate and complete full feasibility based on live real time sales of product. This is expected to allow the Frances Creek project to be valued with a NI 43-101 defined reserve."
