S&P/TSX* Global Mining Index Goes Live

TSX Group Inc. announces the launch of the S&P/TSX Global Mining Index on Tuesday June 12, 2007. Created with Standard and Poor’s – the leading global provider of independent research, ratings and indices – the Index will offer investors wide exposure to the world’s mining markets by providing an investable representative index of publicly traded international mining companies.

The S&P/TSX Global Mining Index provides a basis for innovative index-linked investment vehicles; The first such vehicle, Claymore S&P/TSX Global Mining ETF, will begin trading on June 12, 2007.

TSX Group’s equity exchanges are the world’s leading mining markets. More than 80% of the total number of mining equity financing deals in the world were completed by TSX Group issuers in 2006. Almost 60% of global mining companies are currently listed on a TSX Group exchange.

“The launch of the S&P/TSX Global Mining Index is a natural extension of our role as the world’s leading mining exchange group,” said Richard Nadeau, Senior Vice President, Toronto Stock Exchange. “This is a very positive development for our listed issuers and for mining investors.”
