Rio Tinto's ASX-listed shares hit their highest point in almost 11 years in morning trade, following a buy call from Goldman Sachs and news Vale's Brucutu iron ore mine is unlikely to return to full capacity "any time soon".

The miner's London-listed shares had peaked in mid-April.

Meanwhile, the Saudi Arabian Mining Company, known as Maaden, closed down 9.5% yesterday amid reports it was considering a raising of up to $5 billion through a rights offering.

The offering would be the largest since Bayer AG raised $7 billion last June, according to Bloomberg.

US and UK market futures are indicating a positive start today after both were closed for holidays yesterday.
