Mining giant Rio Tinto reported record first half of the year cash flow of $5.641 billion, an 11 percent increase from the first half of 2006. Diamond mining gross sales revenue totaled $445 million, up from $411 million in 2006.

The company’s net earnings were $3.253 billion, down 14 percent from 2006’s $3.796 billion, which was mainly a result of an impairment of Argyle.
