The Turnagain nickel project in northern British Columbia is emblematic of the likely next class of nickel producers. Low-grade ultramafic nickel projects such as Turnagain have many similarities with copper porphyry projects: massive deposits with high-throughput and low per unit cash flow, but their mineralogy can be challenging with numerous alteration minerals, variations in nickel deportment, and wide variations in nickel recovery. Project benefits can include significant by-product credits, and the ability to reduce greenhouse gas footprint through carbon mineralization in tailings—the most permanent carbon sequestration. The presentation will describe the Turnagain project and ore, and the mineral processing and geometallurgical programme undertaken to reduce technical risk.
