Queen Elizabeth II studies a piece of rock from the San Jose Mine given to her by the President of Chile, Sebastian Pinera, centre, who was accompanied by his wife Cecilia Morel Montes, left, during a private meeting at Buckingham Palace in central London, Monday Oct. 18, 2010. Thirty three miners were trapped underground for 69 days at the San Jose mine in Chile and have now all been rescued. Pinera is in London as part of a European tour, after the dramatic extraction of the men from the San Jose mine. He's seeking to capitalize on the wave of international admiration for the rescue to burnish Chile's image abroad. (AP Photo/John Stillwell, Pool)
