Lonmin, the world’s third largest platinum producer, has shut down a second furnace facility following a technical problem, it said on Wednesday.
The company said it had detected electrode breaks in the furnace, which were creating an unstable and high temperature-operating environment.
The stoppage is expected to only last a maximum of 21 days, the British producer said, and should allow the integrity of furnace conditions to be addressed.
The company was forced to halt its Number One Furnace earlier this month in order to fix a leak, although the three smaller Pyromets continue to operate.
Lonmin says work on the number one furnace is progressing well and on schedule.
“We expect 2015 sales to be back end loaded into the second half of the 2015 financial year and there will be an increased build up of concentrate stocks, which we expect to unwind by year end,” the company added.
“We continue to explore commercial ways of mitigating the stock build up. We expect our net borrowings to further increase at the end of March 2015 as a direct result of the lower sales volumes in the first half, but they are expected to remain within our borrowing facilities. Our sales guidance for 2015 financial year remains unchanged,” it added.
The company added that it will update the market when it releases its first quarter production results on January 29.
Earlier this year, Lonmin noted a decline in both production and profit for the year ended September 30, as strikes in South Africa and reduced platinum prices hit the producer.
In January, South African majority union AMCU downed tools demanding a basic wage of 12,500 rand from the three largest PGM producers in South Africa, including Lonmin. An agreement was reached on June 24.
The company lost 391,000 platinum saleable ounces due to the five-month strike. Underlying profit before tax at $46 million was considerably lower than the $158 million in 2013 and revenue during this period was $965 million against $1,520 million in the corresponding period of 2013.
