UPDATE 1-Jiangxi Copper second quarter profit rises but inventory, writedowns weigh

* Smelter’s H1 profit down 42.7% y/y; Q2 net up around 5%

* Revenue up 40% y/y as copper, gold rally and production jumps

* Makes provisions for fixed asset, inventory impairment; bad debt (Adds detail on provisions for impairments in paras 9 and 10)

BEIJING, Aug 28 (Reuters) - China’s Jiangxi Copper Co reported a 5% rise in second-quarter profit as higher production and a rally in copper and gold prices cushioned the impact of the coronavirus and writedowns on inventory and assets.

For the first half, net income fell 42.7% to 745.3 million yuan ($108.6 million), a filing to the Shanghai Stock Exchange showed.

That implies a profit of 585 million yuan for the second quarter, up from 558 million yuan a year earlier. In the first quarter of this year, Jiangxi Copper recorded its lowest earnings since 2017.

The Nanchang-based firm is one of the biggest copper smelters in China, the world’s top metals consumer.

London copper prices rose more than 20% in the second quarter, completing a Chinese demand-driven recovery after tanking in the first quarter as the coronavirus shattered consumption.

Jiangxi Copper’s production volumes also climbed, with copper cathode output up 6.9% in January-June at 800,600 tonnes, putting the company more or less on track to hits its annual target of 1.65 million tonnes.

That helped propel a 39.9% jump in first-half revenue to 146.99 billion yuan.

The company also cashed in on a surge in precious metal prices, with gold production almost tripling to 38.5 tonnes in the first half and silver output up 222.4% to 544.85 tonnes following the inclusion of subsidiary Shandong Humon Smelting Co’s output on its books from July 2019.

In a separate filing, Jiangxi Copper said it had made a 221.8 million yuan provision in the first half for an impairment on fixed assets after deciding to close loss-making subsidiary Dongtong Mining Co. It also made a 202.13 million yuan provision for a writedown of inventories.

Total provisions for impairment of assets came to 502.68 million yuan, including 48.72 million yuan for bad debt related to overdue loans to commodities trader Tewoo Group. ($1 = 6.8647 Chinese yuan renminbi) (Reporting by Tom Daly; editing by Jason Neely and Susan Fenton)
