Kirkland Lake Gold Inc. (the “Company”) is pleased to announce it will be added to the S&P/TSX Global Gold Index effective Monday, June 18, 2007. The Company will also be a constituent part of the new S&P/TSX Global Mining Index to be created on June 12, 2007.

“We are pleased that Kirkland Lake was added to the prestigious Global Gold Index and included in the new Global Mining Index,” said Brian Hinchcliffe, Company President and CEO. “Given the global strength and positive outlook for the mining sector, we feel the addition to the Gold Index and inclusion in the new Mining Index should benefit our shareholders with increased visibility and liquidity.”

About the Company

The Company purchased the Macassa Mine and the 1,500 ton per day mill along with four former producing gold properties – Kirkland Lake, Teck-Hughes, Lake Shore and Wright Hargreaves – in December 2001. These properties, which have historically produced some 22 million ounces of gold, extend over seven kilometres between the Macassa Mine on the east and Wright Hargreaves on the west and, for the first time, are being developed and explored under one owner. This camp is located in the Abitibi Southern Greenstone Belt of Kirkland Lake, Ontario, Canada.
