COPENHAGEN, Denmark (AP) — Greenland's hopes of a mining boom are shrouded in uncertainty as voters on the ice-capped Arctic island decide Friday who will replace a local government that collapsed after its leader admitted to using taxpayers' money for private trips. Greenland has governed its own affairs since 1979 but its economy depends on an annual grant of 3.6 billion kroner ($600 million) from Denmark. Since gaining self-rule, the island's local politics have been plagued by corruption, nepotism and other scandals. The giant island's iron ore, zinc, gold, diamonds, rare earths and other minerals are expected to become more accessible as the ice sheet melts due to global warming, but no exploitation licenses have been issued.
