Updates from Rio Tinto and Michael Page

Another tumble for the FTSE 100, dipping 40 points to 6,343 yesterday following more pessimistic US and Chinese numbers. Miner Fresnillo sank a significant -15.16% while GlaxoSmithKline was the day's biggest climber, up +3.89%.

Overnight, news of the US bombings worried Asian investors with the Hang Seng dipping -0.44%; the Dow Jones fell-1.79% yesterday.

First off, Rio Tinto. In its quarterly production report Rio Tinto claims operations achieved a solid performance in the first quarter. At Bingham Canyon [open pit mine in Utah], last week's pit wall slide will have a significant impact on our copper production this year, the company warns.

Its two major growth projects in the Pilbara and in Mongolia achieved significant milestones in the first quarter Rio Tinto claims. Both projects remain on track for first production this year and - so the company claims - are poised to deliver "attractive" returns for shareholders in the future.

"My streamlined Executive Committee structure," says boss Sam Walsh, "is now in place and demanding targets for 2013, including for cash cost savings, are locked into our performance measures. We are making good progress in achieving our cost reduction targets and other priorities for 2013."

Next, a Q1 update from international recruiter Michael Page. The Group reported gross profit of £127m, up +0.2% on the fourth quarter, although down -6.7% year-on-year. Conditions across all regions were described as "tough" with "weak" market confidence. The EMEA Region saw the sharpest Q1 tumble, down -15.1%.

"We saw good performances in some of our regions," says chief exec Steve Ingham, "with Asia and North America delivering the strongest gross profit performances up +14% and +16% respectively year-on-year in constant currency. Our offices in Greater China, Japan, Mexico, the Middle East, and the USA performed particularly well."

However businesses in France and Germany, where Page operates predominantly in permanent recruitment, saw numbers slip -17% and -27% respectively. Total headcount for the Group has been cut by 57 to 5,042 from the year end 2012.

Finally, RIT Capital Partners. Shareholders will be told that RIT's net asset value per share on 31 March was 1,344.0p (before the deduction of the interim dividend of 14p per share payable on 26 April 2013). This represents an increase in net asset value of 12.8% in the first quarter of 2013.

This was RIT's second best quarterly performance in the past seven years. It also represents the highest announced net asset value in the Company's history, the company claims.

The 2013 Annual General Meeting of RIT Capital Partners plc will be held at Spencer House, 27 St James's Place, London, SW1A 1NR at 11am today.
