TROU DU NORD, Haiti (AP) — Its capital is blighted with earthquake rubble. Its countryside is shorn of trees, chopped down for fuel. And yet, Haiti's land may hold the key to relieving centuries of poverty, disaster and disease: There is gold hidden in its hills — and silver and copper, too.

A flurry of exploratory drilling in the past year has found precious metals worth potentially $20 billion deep below the tropical ridges in the country's northeastern mountains. Now, a mining company is drilling around the clock to determine how to get those metals out.

In neighboring Dominican Republic, workers are poised to start mining the other side of this seam later this year in one of the world's largest gold deposits: 23 million ounces worth about $40 billion.
