Nan Nan Resources Enterprise (HKG:1229) expects a minimum profit of HK$30 million for the six months ended Sept. 30, higher than HK$17.4 million logged for the same period last year, a Monday Hong Kong bourse filing said.

The coal mining, renewable energy, and information technology company attributed the expected increase to a rise in sales of coal and a net exchange gain during the period compared with a net exchange loss last year.

The company's shares closed over 1% higher on Monday.
