South African aluminum producer Hulamin Ltd. (HLM.JO) Tuesday said BHP Billiton Ltd. (BHP) has agreed to continue supplying extrusion billet until September and rolling slab until December 2010.

"Hulamin is assessing a number of options to ensure that its future requirements in respect of extrusion billet and rolling slab are satisfied, and that its growth plans are not affected," it said.

The company sources about half of its billet and 30% of its rolling slab from BHP Billiton's Bayside cast house and produces the balance in its own facilities.

Hulamin in April issued a cautionary statement to the Johannesburg bourse saying it was in undisclosed discussions with BHP that could affect its share price.

Bayside, which operates in the South African port city of Richards Bay and has been operating since 1971, produces aluminum billet, slab and rod.

At 0920 GMT, Hulamin's shares were trading 0.1% lower at 11 rand amid a mildly positive broader market. The stock has fallen almost 17% this year.
