Lithium hopeful Ioneer on Wednesday told shareholders that its agreement with US greens group the Center for Biological Diversity would have "no impact" on the ongoing activities at its Rhyolite Ridge lithium/boron project, in Nevada. Mining Weekly Online earlier this week reported that the ASX-listed company had struck a deal with the Center, agreeing to notify the conservationist group of any additional mining or exploration plans at the site, or any plans to build the mine.
