SMM9 March 3: it is reported that BHP Billiton plans to buy back up to $1.9 billion of bonds to reduce debt, reduce related interest costs and continue to optimize the group's capital institutions.

The world's largest mining company has made huge profits from iron ore, which soared to more than $100 a tonne and now has large cash reserves.

BHP's underlying profit from continuing operations for the year ended June 30 was $9.06 billion, mainly due to the negative impact of the epidemic offset by higher iron ore prices.
