Ulan Bator, Mongolia
Small-scale miners watch as a colleague uses a pan to sift gold on a small hill overlooking grasslands located around 200 km (125 miles) south-west of the Mongolian capital city Ulan Bator in this April 4, 2012 file picture. In the last five years, dwindling legal gold supplies and a spike in black market demand from China have made work much more lucrative for Mongolia's "ninja miners" - so named because of the large green pans carried on their backs that look like turtle shells. For thousands of dirt-poor herders, the soaring prices alone are enough to justify years of harassment, abuse and hard labour.
