Illegal miners at a copper and cobalt mine run by Glencore in southeastern Congo defied a deadline on Tuesday to vacate the site, a union official said, raising fears of a potentially violent standoff. A landslide last Thursday at the Kamoto Copper Company (KCC) concession, majority-owned by a subsidiary of Glencore, killed 43 people and led Democratic Republic of Congo's government to promise to remove the miners.
