A gold rush is shaping up in Haiti. Billions of dollars of precious metals are thought to be buried in the hills. So far Canadian and American mining companies have invested more than $30m collecting samples, building roads and digging. Nearly 15 percent of Haiti's territory is now under license to North American mining firms. While the gold rush is attracting the interest of international investors, locals in the country where 70 per cent of people are unemployed fear the companies' promises will not be upheld.
