The Nanchang-based company's net income was 1.3 billion yuan ($183.28 million) for January-June, according to a filing to the Shanghai Stock Exchange, while revenues stood at 105 billion yuan, up 0.5% from a year earlier.
Jiangxi Copper had in April reported first-quarter net profit of 742 million yuan, implying a second-quarter profit of 558 million yuan, up 9% from a year earlier, according to Reuters calculations. That marks its best second-quarter result since 2015, Refinitiv Eikon data shows.
Benchmark three-month copper on the London Metal Exchange averaged $6,175.50 a tonne in the first half, 5.6% lower than a year earlier, Jiangxi Copper said.
Prices for copper, considered an economic bellwether, rose in the first quarter on fears of mine supply disruption but dropped over the April-June period as Sino-U.S. trade tensions - and their potential impact on demand for industrial metals - returned to the fore.
Because there is no major difference between supply and demand levels, "it is expected that copper prices will continue to be dominated by the macro situation in the second half of the year," the company said.
Jiangxi Copper's refined copper cathode output came in at 749,300 tonnes in the first half, up 3.5% from a year earlier. It had in March set a 2019 output target of 1.44 million tonnes.
The company, which operates copper mines as well as smelters, also produced 102,000 tonnes of copper concentrate during the six months, up 0.2% year-on-year and 12.88 tonnes of gold, down 0.2% from a year earlier.
