Whitbread and the miners are lifting the blue chip index higher on Tuesday afternoon, with the FTSE 100 up 51 points at 5,744 as of 13:55.Strong sales growth at Costa coffee shops helped hotel and restaurant group Whitbread to offset subdued activity in its restaurant division to grow total sales by 9.2% in first quarter. Shares have jumped by 7%.Mining stocks are on the rise, as copper, gold and silver futures head higher. Kazakhmys, Antofgasta and Lonmin are among the top ten risers.Sector peer Rio Tinto is also firmer following its notice that it is to raise its stake in Toronto- and New York-listed Ivanhoe Mines after exercising its remaining warrants for the ongoing development of the copper and gold Oyu Tolgoi project in southern Mongolia. Oil giant BP is heading higher after tying up another loose end relating to disputes over who should carry the can for the Deepwater Horizon tragedy in the Gulf of Mexico last year by coming to a settlement with US contractor Weatherford. Rising oil prices are sure to be helping the share price also, with Petrofac making solid gains.Journeying the other way is brewing giant SABMiller after its £7.30bn offer for Australian rival Foster's Group was rejected by the Foster's board, as it "believes that the proposal significantly undervalues the company." ---BCFTSE 100 - RisersWhitbread (WTB) 1,589.00p +7.00%Kazakhmys (KAZ) 1,286.00p +4.39%Antofagasta (ANTO) 1,258.00p +3.97%Fresnillo (FRES) 1,354.00p +3.60%Petrofac Ltd.
