Johannesburg – Sibanye says its bid to but the Stillwater mine in the US has been approved by more than 80 percent of its shareholders.

The listed miner, which has been transforming into a platinum giant, added on Tuesday in a statement to shareholders that its plan to issue shares to partially pay for the American mine was also approved by shareholders holding more than 80 percent of its stock.

However, the deal is still subject to other customary conditions.

In December, the South African gold and platinum miner said the deal presents the opportunity for it to transform into a premier, global precious metals miner, with a balanced portfolio of gold and platinum group metals assets, at a favourable point in the commodity cycle.

Stillwater is the only US miner of PGM and the largest primary producer of PGM outside of South Africa and the Russian Federation. Located in Montana, US, Stillwater’s operations consist of two underground PGM mines (the Stillwater Mine and East Boulder Mine), the Blitz Project and the Columbus metallurgical complex.

The announcement of the deal saw its shares plunge shortly after.

The company has said it plans to raise $1 billion from shareholders and a further $1 billion in debt, most likely bonds, to pay for the acquisition of Colorado-based Stillwater Mining Company.

The remainder of the loan will be repaid through a combination of sources such as commodity-streaming deals, the company said earlier this month.

It initially announced it would raise $750 million to $1 billion from shareholders before saying in February it may increase this amount to $1.3 billion.

CEO Neal Froneman says in the statement that the company thanks shareholders for their support for this transaction which “represents a unique and transformative opportunity to acquire world class, low-cost international PGM assets.

“Stillwater offers near-term organic production growth through the Blitz project, further enhancing Sibanye’s asset portfolio and will create in Sibanye, a globally competitive South African mining champion with a unique commodity mix”.
