Sibanye Gold said on Monday it remained committed to concluding the acquisition of two platinum assets despite lower prices as it awaited the approval of shareholders and South Africa’s anti-trust authorities.

The bullion producer said it expected a decision from the South African Competition Commission in March 2016 while shareholders are set to vote in January on the acquisition of Aquarius Platinum and Anglo American Platinum’s Rustenburg mine.

Platinum prices sank 16% in November to near seven-year lows on prospects of a U.S interest rate hike and ongoing concerns of oversupply. Despite this Sibanye said it would go ahead with the transactions.

“As highlighted when these transactions were announced, whilst near-term economic headwinds and supply side factors have resulted in downward pressure on metal prices, the long-term outlook for PGM demand remains constructive,” Chief Executive Neal Froneman said.
