Koza Altin Isletmeleri AS, a Turkish gold miner, and Goldas Kuyumculuk Sanayi AS, a jewelry producer, climbed after figures showed national exports of precious metals soared last month.
Koza Altin added 7 percent to 33.70 liras at the close in Istanbul, the biggest gain since at least February 2010. Goldas rose 1.9 percent to 54 kurus.
The $1.5 billion increase in gold, jewelry and precious metal exports in April was mostly driven by Iran, which bought $1.2 billion worth of precious metals and jewelry in the month from Turkey, according to figures released yesterday by the state statistics agency.
Turkey exported $282 million worth of gold and precious metals in April last year.
