As a local tribe prepares to sue Vancouver-based Midas Gold over poor water quality in the Stibnite mining district of central Idaho, in the US, the company on Thursday committed to do its bit to improve water quality in the area where mining had been taking place for more than a century. Subsidiary Midas Gold Idaho CEO Laurel Sayer said in a statement that the company shared the Nez Perce Tribe’s concern over water quality in the Stibnite mining district, where water quality sampling had showed high arsenic and antimony levels, "far beyond" what was considered acceptable for drinking water or aquatic life standards.
