Aowei Holding (HKG:1370) said it expects to post a loss attributable to shareholders of up to 90 million yuan for the six months ended June 30, widening from 50.6 million yuan a year earlier, according to a Thursday Hong Kong bourse filing.

Shares of the iron ore mining firm were down over 1% in late-morning trade on Friday.

The company cited the expected loss to the suspension of mining at a subsidiary's open-pit iron mine and a drop in iron ore concentrate prices.
