The Biden administration Thursday approved a massive lithium and boron mine in southern Nevada, overriding some environmentalists’ protests that it could drive an endangered wildflower to extinction. … Some environmentalists have also raised alarm about the mine’s water consumption, given a historic drought gripping much of the American West. But Bernard Rowe, Ioneer’s managing director, said the company is taking steps to mitigate these concerns. The mine will be “very efficient with water. We recirculate about 50 percent of our water,” Rowe said on a call with reporters Thursday, adding that “we’ve designed the project to be very, very respectful of environmental sensitivities.”
