LONDON, April 12 (Reuters) - European shares edged up early on Monday after euro zone finance ministers approved an emergency aid mechanism for Greece, and with UBS <UBSN.VX> gaining after it said first-quarter profit surged.
But weaker mining and oil shares capped gains.
At 0839 GMT, the FTSEurofirst 300 <
> index of top European shares was up 0.1 percent at 1,102.63 points, after rising 1.3 percent on Friday to an 18-month closing high, and notching up its sixth straight week of gains.The European benchmark is up more than 70 percent from its lifetime low of March 9, 2009.
"It's still bull market conditions," said Bernard McAlinden, investment strategist at NCB Stockbrokers. "Worries that we might lurch back into a deflationary slump are lessening."
He added that equities "are climbing against the background of low yield on alternative assets".
Swiss banking group UBS <UBSN.VX> rose 3.5 percent after it said, in a surprise update, that first-quarter pre-tax profit would be at least 2.5 billion Swiss francs ($2.33 billion), adding client withdrawals had slowed at all its business divisions. [

Greek banks <.FTATBNK> soared 8.4 percent. National Bank <NBGr.AT>, EFG Eurobank <EFGr.AT>, Piraeus Bank <BOPr.AT> and Alpha Bank <ACBr.AT> rose between 9.1 and 13.8 percent.
Euro zone finance ministers approved a giant 30-billion-euro ($40 billion) emergency aid mechanism for debt-plagued Greece on Sunday, but stressed Athens had not requested the plan be activated yet. [
]"The market seems to be able to compartmentalise the Greek thing and pull it apart from the bigger picture," said McAlinden. "I wouldn't see the Greek thing as being good news. It's just some relief from the embarrassment of default."
Miners were mostly lower, even as copper prices remained near 20-month highs, as the dollar weakened.
Antofagasta <ANTO.L> fell 1.6 percent after Citigroup cut its rating to "hold" from "buy".
