Trevali lays strong foundation for future Halfmile-Stratmat project scenarios

A preliminary economic assessment (PEA) on Canadian pure-play zinc producer Trevali Mining's fully owned Halfmile-Stratmat zinc/lead/silver deposits, located in the Bathurst Mining Camp of New Brunswick, has produced strong results for developing either a standalone operation, or leveraging existing infrastructure at the nearby Caribou mine. The Vancouver-based miner reported on Monday that the base case study, outlining a new 3 000 t/d concentrator at the Stratmat site, which will treat underground ore from both the Stratmat and Halfmile deposits, generates an after-tax net present value (NPV), using an 8% discount rate, of C$99-million and an internal rate of return (IRR) of 19%.
