Why is nickel essential to electrification? And how can prospectors and geologists find new nickel deposits? This session addresses these two questions, and it considers the answers in the light of the world's growing emphasis on sustainability.

The Government of Quebec has been reported as considering shutting the Horne smelter because of the potential effects of fugitive arsenic and cadmium on people who live near the smelter. Furthermore, the Armstrong nickel project in Western Australia has never been developed because of its high arsenic content. The prospectors and geologists who discover a nickel deposit, and the operators who extract economic metals from it should, therefore, be concerned not only about mitigation of the release of greenhouse gases from their deposit, they should also be aware of the potential of their deposit to introduce deleterious materials, notably arsenic, into the environment.
